Description
Technical Field
The present application relates to the technical field of purification of organic liquids, and in particular, to an apparatus and a method for purifying an organic liquid.
Background
As the power consumption of the server device increases, the heat dissipation requirements are more stringent. Servers are evolving from a traditional air-cooled cooling mode to a liquid-cooled cooling mode. In a liquid-cooled environment, there are cold plate heat dissipation, which is a mode in which a cooling liquid passes through a cold plate/tube, which contacts a heat sink or part, to transfer heat. Compared with cold plate type heat dissipation, immersion type heat dissipation is to directly soak a heat dissipation device in cooling liquid, and transfer heat through the heat capacity or phase change process of the cooling liquid. The occurrence of submerged heat dissipation provides possibility for the design of multiple components, high density and large power consumption of the server, so that the PUE value of the data center is lower and lower.
The cleanliness of the immersed environment is one of the keys for long-term stable operation of the immersed liquid cooling server. In an immersed environment, the source of liquid contamination is diverse, such as residue contamination during the motherboard PCBA production process, debris contamination during cabinet and host installation, contamination during maintenance and repair, and the like. Contaminants in the cooling fluid can directly affect the proper operation of the components immersed therein. Therefore, it is necessary to purify the coolant after a period of use.
Most of the submerged liquid cooling servers in the prior art incorporate a filtering device in the pipeline through which the cooling liquid flows to perform on-line filtering of the cooling liquid, such as CN215121663U, however, this can only filter solid particulate matters, and is difficult to remove for liquid contaminants mixed in the cooling liquid.
Disclosure of Invention
In view of this, it is necessary to provide an apparatus and a method for purifying an organic liquid, which solve the problem that the liquid contaminants mixed in the coolant are difficult to remove, because the on-line filter device in most of the immersion-type liquid cooling servers in the prior art can only filter solid particles.
A purification device for an organic liquid, comprising:
A filtering device for filtering the organic liquid; and, a step of, in the first embodiment,
and the inlet of the distillation device is used for being communicated with the outlet of the filtering device so as to receive the filtered organic liquid, and the distillation device is used for distilling the filtered organic liquid so as to separate organic components to be extracted from the organic liquid.
When the organic liquid purifying device is used, the organic liquid is led into the filtering device, so that solid pollutants in the organic liquid are filtered by the filtering device. Because the inlet of the distillation device is communicated with the outlet of the filtering device, the filtered organic liquid flows into the distillation device from the filtering device. The distillation device is used for distilling the filtered organic liquid, so that liquid pollutants in the organic liquid can be removed, and organic components to be extracted in the organic liquid can be separated. Namely, the organic liquid purifying device can effectively remove solid and liquid pollutants in the organic liquid and purify the organic liquid.
In an embodiment, the organic liquid purifying device further includes a first concentration detecting device, where the first concentration detecting device is configured to detect a concentration of an organic component to be extracted in the organic liquid upstream of the filtering device.
The first concentration detection device in the embodiment of the application can be used for detecting the concentration of the organic components to be extracted of the cooling liquid (namely, the organic liquid upstream of the filtering device) in the server so as to judge whether the cooling liquid is polluted or the pollution degree, so that the coping strategy can be developed in time.
In one embodiment, the organic liquid purifying device comprises a liquid inlet pipe, and an outlet of the liquid inlet pipe is communicated with an inlet of the filtering device; the first concentration detection device is connected with the liquid inlet pipe; the first concentration detection device is configured such that when the detection result indicates that the pollution degree of the organic liquid exceeds the standard, the outlet of the first concentration detection device is opened, so that the organic liquid can flow to the inlet of the filtering device through the outlet of the first concentration detection device.
When the detection result represents that the pollution degree of the organic liquid exceeds the standard, the outlet of the first concentration detection device is opened, so that the organic liquid can flow out from the outlet of the first concentration detection device, and then flows through the liquid inlet pipe to enter the filtering device, and automatic purification is performed.
In an embodiment, the first concentration detection apparatus is any one of a microwave concentration detector, an ultrasonic concentration detector, a refractive concentration detector, and an infrared concentration detector.
In an embodiment, the purifying device of the organic liquid further comprises a second concentration detecting device, and the second concentration detector is used for detecting the concentration of the organic component to be extracted in the organic liquid after filtration and before distillation. Since the concentration of the organic components to be extracted is changed after the organic liquid is filtered out of the solid contaminants, the filtering effect can be judged by detecting the concentration of the organic components to be extracted in the organic liquid after the filtering and before the distillation according to the second concentration detector. If the filtering effect is qualified, the filtered organic liquid can enter a distillation device to be purified continuously. If the filtering effect is not qualified, further filtering is needed.
In an embodiment, the second concentration detection apparatus has a liquid inlet and a first liquid outlet, the liquid inlet of the second concentration detection apparatus is communicated with the outlet of the filtering apparatus, and the first liquid outlet is used for being communicated with the inlet of the distillation apparatus; the second concentration detection device is configured to open the first liquid outlet when the detection result represents that the filtering effect is qualified.
When the filtered organic liquid enters the second concentration detection device through the liquid inlet of the second concentration detection device, the concentration of organic components to be extracted in the filtered organic liquid can be detected, so that the filtering effect of the organic liquid can be judged. And when the filtering effect is qualified, the first liquid outlet is opened, so that the filtered organic liquid automatically enters the distillation device from the first liquid outlet to continue purifying. Otherwise, the first liquid outlet is closed, so that the filtered organic liquid cannot enter the distillation device. Thus, the solid pollutants in the organic liquid can be sufficiently filtered, the solid pollutants are prevented from entering the distillation device, and the solid pollutants are further prevented from being distilled or damaging the heater.
In an embodiment, the second concentration detection apparatus has a second liquid outlet, and the second liquid outlet is used for communicating with the filtering apparatus; the organic liquid purifying device further comprises a liquid returning power device, wherein the liquid returning power device is used for providing power for the organic liquid to flow into the filtering device from the second liquid outlet; the second concentration detection device is configured to open the second liquid outlet when the detection result represents that the filtering effect is unqualified, and the liquid returning power device is started.
The second concentration detection device is configured to, when the detection result represents that the filtering effect is unqualified, the second liquid outlet is opened, and the liquid return power device is started, so that the power provided by the liquid return power device can enable the organic liquid to flow into the filtering device from the second liquid outlet, the organic liquid can be filtered again, and the filtering effect is further improved through repeated filtration. If the filtering effect is still not qualified after repeated filtering (for example, three times of filtering), the filtering performance of the filtering piece is insufficient, and a worker can replace the filtering piece in time.
In one embodiment, the organic liquid purifying device further comprises a power device for providing power for the organic liquid flowing into the filtering device and power for the organic liquid flowing from the filtering device into the distillation device. The power provided by the power device can improve the flowing speed of the organic liquid in the organic liquid purifying device so as to match the flow speed of the cooling liquid in the server, thereby enabling the organic liquid purifying device to stably operate.
In an embodiment, the organic liquid purifying device further comprises a flow rate detecting device for detecting a flow rate of the organic liquid flowing into the filtering device and/or a flow rate of the organic liquid flowing from the filtering device into the distilling device.
By detecting the flow rate of the organic liquid flowing in the organic liquid purifying device by the flow rate detecting device, the power device can be adjusted according to the detection of the flow rate detecting device, so that the speed of the organic liquid flowing in the organic liquid purifying device can be matched with the flow rate of the cooling liquid in the server.
In one embodiment, the filter element is a ceramic membrane element. The ceramic membrane is a semi-permeable membrane, which not only can filter out solid pollutants, but also has selective permeability and only allows ions and small molecular substances to pass through. Therefore, the liquid pollutants with larger molecules can be filtered by utilizing the selective permeability of the semipermeable membrane, so that a better filtering effect is achieved.
A method for purifying an organic liquid, which is realized by the organic liquid purifying apparatus according to any one of the above embodiments, comprises the steps of:
introducing an organic liquid into a filtration device to filter the organic liquid with the filtration device;
The filtered organic liquid flows into a distillation device from a filtering device, and the distillation device distills the filtered organic liquid so as to separate organic components to be extracted from the organic liquid.
In the above method for purifying an organic liquid, the organic liquid is introduced into a filter device to filter solid contaminants in the organic liquid by the filter device. Because the inlet of the distillation device is communicated with the outlet of the filtering device, the filtered organic liquid flows into the distillation device from the filtering device. The distillation device is used for distilling the filtered organic liquid, so that liquid pollutants in the organic liquid can be removed, and organic components to be extracted in the organic liquid can be separated. Namely, the organic liquid purifying device can effectively remove solid and liquid pollutants in the organic liquid and purify the organic liquid.
In one embodiment, the method for purifying an organic liquid further comprises, prior to the step of introducing the organic liquid into the filter device to filter the organic liquid with the filter device,
detecting the concentration of organic components to be extracted in the organic liquid upstream of the filtering device by using a first concentration detection device;
and if the detection result indicates that the pollution degree of the organic liquid exceeds the standard, executing the step of guiding the organic liquid into the filtering device so as to filter the organic liquid by using the filtering device.
The concentration of organic components to be extracted in the organic liquid at the upstream of the filtering device is detected by the first concentration detection device, and if the detection result represents that the pollution degree of the organic liquid exceeds the standard, a worker can timely start the purification device of the organic liquid to purify the organic liquid.
In one embodiment, the method for purifying an organic liquid further comprises, before the step of flowing the filtered organic liquid from the filtering device into the distillation device,
detecting the concentration of the organic components to be extracted in the filtered organic liquid by using a second concentration detection device;
if the detection result indicates that the filtering effect is qualified, executing the step that the filtered organic liquid flows into the distillation device from the filtering device;
and if the detection result indicates that the filtering effect is not qualified, returning the filtered organic liquid to the filtering device for filtering, or replacing a filtering piece of the filtering device.
Since the concentration of the organic components to be extracted is changed after the organic liquid is filtered out of the solid contaminants, the filtering effect can be judged by detecting the concentration of the organic components to be extracted in the organic liquid after the filtering and before the distillation according to the second concentration detector. If the filtering effect is qualified, the filtered organic liquid can enter a distillation device to be purified continuously. If the filtering effect is not qualified, further filtering is needed, so that the organic liquid can be filtered again, and the filtering effect is further improved through repeated filtering. If the filtering effect is still not qualified after repeated filtering (for example, three times of filtering), the filtering performance of the filtering piece is insufficient, and a worker can replace the filtering piece in time.

Referring to fig. 1, an embodiment of the present application provides a purifying apparatus for organic liquid, including a filtering apparatus and a distillation apparatus. The filter device is used for filtering the organic liquid. The inlet of the distillation device is used for communicating with the outlet of the filtering device to receive the filtered organic liquid, and the distillation device is used for distilling the filtered organic liquid to separate the organic components to be extracted from the organic liquid.
The purification device for the organic liquid can be used for removing solid pollutants and liquid pollutants in the organic liquid so as to extract clean organic components in the organic liquid, thereby achieving the purpose of purifying the organic liquid. When the organic liquid purifying device is used, the organic liquid is led into the filtering device, so that solid pollutants in the organic liquid are filtered by the filtering device. Because the inlet of the distillation device is communicated with the outlet of the filtering device, the filtered organic liquid flows into the distillation device from the filtering device. The distillation device is used for distilling the filtered organic liquid, so that liquid pollutants in the organic liquid can be removed, and organic components to be extracted in the organic liquid can be separated. Namely, the organic liquid purifying device can effectively remove solid and liquid pollutants in the organic liquid and purify the organic liquid.
The cooling liquid used in the liquid cooling server is mostly an organic liquid, and therefore, the purification device for the organic liquid can be used for purification. Specifically, the inlet of the filtering device may be in communication with the outlet of the cooling fluid of the server via a conduit (e.g., inlet tube 130), such that the cooling fluid of the server may flow into the filtering device via the conduit to be filtered. The outlet of the filtering device is communicated with the inlet of the distillation device through a pipeline, so that the filtered cooling liquid can flow into the distillation device. The outlet of the distillation apparatus may be in communication with the inlet of the cooling fluid to the server via a conduit (e.g., outlet 250) so that the purified cooling fluid may be returned to the server for use. Therefore, the polluted cooling liquid discharged from the outlet of the cooling liquid of the server flows back to the server after being purified by the organic liquid purifying device, the process can be finished on line in a server room, the cooling liquid is not required to be conveyed to a special place for purification, the transportation cost and the time are saved, the server is not required to be stopped, and the purifying work of the cooling liquid is greatly simplified.
In one embodiment, the filter apparatus includes a filter vessel 110 and a filter member 120 positioned within the filter vessel 110, the filter member 120 for filtering the organic liquid. In use of the organic liquid purifying apparatus, the organic liquid is introduced into the filtering container 110 to filter solid contaminants in the organic liquid by the filtering member 120. The inlet of the filter means is the inlet of the filter vessel 110.
In one embodiment, the distillation apparatus includes a distillation vessel 210, a heater 220, a condenser 230, and a collection vessel 240, with an inlet of the distillation vessel 210 being adapted to communicate with an outlet of the filtration apparatus to receive the filtered organic liquid. The heater 220 is used for heating the filtered organic liquid to vaporize the organic components to be extracted in the organic liquid. The condenser 230 is used for condensing and liquefying the vaporized organic component to be extracted, and the collection vessel 240 is used for receiving the liquefied organic component to be extracted. The inlet of the distillation apparatus is the inlet of distillation vessel 210. The outlet of the distillation apparatus may be the outlet of the collection vessel 240.
Since the inlet of the distillation vessel 210 communicates with the outlet of the filtering device, the filtered organic liquid flows from the filtering device into the distillation vessel 210. The heating device heats the organic liquid in the distillation vessel 210 to vaporize the organic components to be extracted in the organic liquid while the liquid contaminants remain at the bottom of the distillation vessel 210. The condenser 230 condenses and liquefies the vaporized organic components to be extracted, so that the organic components to be extracted enter the collection container 240 in a liquid form, and clean organic components in the organic liquid can be separated and extracted, i.e. solid and liquid pollutants in the organic liquid can be effectively removed, and the organic liquid is purified.
It should be noted that, the boiling point of the liquid contaminant mixed in the cooling liquid of the server is generally higher than the boiling point of the organic component to be extracted in the cooling liquid, so that the heating temperature of the heater 220 is only required to reach a temperature above or near the boiling point of the organic component to be extracted, so that the organic component to be extracted is vaporized, and other liquid contaminants remain at the bottom of the distillation container 210. A drain 211 may be provided at the bottom of the distillation vessel 210 to drain the liquid contaminants from the drain 211 at the bottom of the distillation vessel 210. The organic components to be extracted are liquefied and collected in the collection container 240.
In the purification of the liquid contaminants having a boiling point lower than the organic components to be extracted, which may exist in the cooling liquid of the server, the heating temperature of the heater 130 is still higher than the boiling point of the organic components to be extracted, so that the organic components to be extracted and the liquid contaminants having a boiling point lower than the organic components to be extracted are vaporized and raised, and enter the collecting container 240 under the condensation action, so that the organic components to be extracted and the liquid contaminants having a boiling point lower than the organic components to be extracted are collected together in the collecting container 240, i.e. the liquid contaminants having a boiling point higher than the organic components to be extracted are removed. The collection vessel 240 may then be left to stand for a period of time, whereby the organic components to be extracted and the liquid contaminants below the boiling point of the organic components to be extracted may be layered within the collection vessel 240, as the organic components to be extracted and the liquid contaminants below the boiling point of the organic components to be extracted are generally immiscible and of different densities.
When the density of the liquid pollutant lower than the boiling point of the organic component to be extracted is higher than that of the organic component to be extracted, the liquid pollutant lower than the boiling point of the organic component to be extracted is positioned at the lower layer, and the organic component to be extracted is positioned at the upper layer. In some embodiments, a drain 241 may be provided at the bottom of the collection vessel 240. Liquid contaminants below the boiling point of the organic components to be extracted in the lower layer of the collection container 240 can be discharged through the liquid discharge port 241 at the bottom of the collection container 240, so that only the organic components to be extracted remain in the collection container 240. Further, a separate liquid return port (not shown) may be formed in the collection container 240 and connected to the inlet of the cooling liquid of the server, so that the organic components to be extracted may be returned to the server.
On the contrary, when the density of the liquid contaminant below the boiling point of the organic component to be extracted is lower than the density of the organic component to be extracted, the liquid contaminant below the boiling point of the organic component to be extracted is located at the upper layer, and the organic component to be extracted is located at the lower layer, the organic component to be extracted can be discharged through the liquid discharge port 241, thereby obtaining separation and extraction. Or a three-way valve is arranged, and the three-way valve is provided with a first valve port, a second valve port and a third valve port. The first valve port is communicated with the liquid discharge port 241, the second valve port is used for discharging organic components to be extracted, and the third valve port is used for discharging liquid pollutants. After the organic components to be extracted are layered with the liquid pollutants, the third valve port is closed, and the second valve port is opened, so that the organic components to be extracted flow out from the first valve port to the second valve port to be separated and extracted, and the second valve port can be communicated with the inlet of the cooling liquid of the server to enable the separated and extracted organic components to directly flow back into the server; and then the second valve port is closed, the third valve port is opened, liquid pollutants with the boiling point lower than that of organic components to be extracted are discharged, and the third valve port can be connected to the waste liquid container, so that the liquid pollutants are directly discharged to the waste liquid container.
The above-mentioned purification device for organic liquid is not limited to purifying the cooling liquid of the liquid cooling server, and in other embodiments, the purification device can be used for purifying other types of organic liquid.
Specifically, the heater 220 may be disposed inside the distillation container 210, or may be disposed below the outside of the distillation container 210.
In the embodiment shown in fig. 1, condenser 230 is located inside distillation vessel 210 and above heater 220. A collection vessel 240 is located within distillation vessel 210 and below condenser 230, with the opening of collection vessel 240 facing condenser 230. The organic component to be extracted is vaporized and rises to meet the condenser 230 and then is liquefied and falls into the collection container 240.
In other embodiments, the condenser and collection vessel may also be located outside the distillation vessel. The distillation container, the condenser and the collecting container are connected in sequence through a pipeline, so that the organic components to be extracted flow out of the distillation container after being vaporized, are liquefied by the condenser and then flow into the collecting container.
In the embodiment shown in fig. 1, the lower end of the filter member 120 protrudes from the bottom of the filter container 110, and the lower end of the filter member 120 is provided with an outlet 121, and the filtered organic liquid is discharged from the filter device through the outlet 121. The outlet 121 of the lower end of the filter 120 is the outlet of the filter device.
In other embodiments, the outlet of the filter device may also be provided in the filter vessel.
Referring to fig. 1, in an embodiment, the purifying apparatus for organic liquid further includes a first concentration detecting apparatus 300, and the first concentration detecting apparatus 300 is used for detecting a concentration of organic components to be extracted in the organic liquid upstream of the filtering apparatus.
The concentration of the organic component to be extracted in the organic liquid upstream of the filtering device is detected by the first concentration detecting device 300, and whether the organic liquid is contaminated or the degree of contamination can be determined according to the concentration of the organic component to be extracted. If the concentration of the organic components to be extracted is insufficient, the condition that more pollutants are mixed, namely the pollution degree of the organic liquid exceeds the standard is indicated, and a worker can timely start the organic liquid purifying device to purify the organic liquid. If the concentration of the organic components to be extracted is sufficient, it means that the organic liquid is not contaminated temporarily or the contamination level is low, and the above-mentioned purification device for the organic liquid may be started temporarily.
In the prior art, the state of each substance in the cooling liquid of the server is unclear and unclear, so that the problem of cooling liquid pollution cannot be dealt with in time. In this regard, the first concentration detection apparatus 300 in the embodiment of the present application may detect the concentration of the organic component to be extracted of the cooling liquid (i.e. the organic liquid upstream of the filtering apparatus) in the server, so as to determine whether the cooling liquid is contaminated or the contamination level, so as to develop the coping strategy in time.
Referring to fig. 1, in one embodiment, the purifying apparatus of the organic liquid includes a liquid inlet pipe 130, and an outlet of the liquid inlet pipe 130 communicates with an inlet of the filtering apparatus. The first concentration detection apparatus 300 is connected to the liquid inlet pipe 130. The first concentration detection apparatus 300 is configured such that when the detection result indicates that the organic liquid pollution level exceeds the standard, the outlet of the first concentration detection apparatus 300 is opened so that the organic liquid can flow to the inlet of the filtering apparatus through the outlet of the first concentration detection apparatus 300.
Specifically, the first concentration detection apparatus 300 has an inlet and an outlet, and when the organic liquid enters the first concentration detection apparatus 300 through the inlet of the first concentration detection apparatus 300, the concentration of the organic component to be extracted in the organic liquid can be detected, so that whether the organic liquid is polluted or not and the pollution degree can be obtained according to the detected concentration value. When the detection result indicates that the pollution degree of the organic liquid exceeds the standard, the outlet of the first concentration detection device 300 is opened, so that the organic liquid can flow out from the outlet of the first concentration detection device 300, and then flows through the liquid inlet pipe 130 to enter the filtering device, and automatic purification is performed.
On the contrary, when the detection result indicates that the organic liquid is not polluted or the pollution degree is light, the outlet of the first concentration detection device 300 is kept in a closed state, and the organic liquid cannot pass through the first concentration detection device 300, so that the organic liquid cannot enter the filtering device, and the organic liquid does not need to be purified.
In the embodiment shown in fig. 1, the first concentration detection means 300 is provided at the inlet end of the inlet pipe 130. The inlet of the first concentration detection apparatus 300 may be communicated with the outlet of the cooling liquid of the server, so that the cooling liquid of the server may enter the first concentration detection apparatus 300 to perform real-time detection, and further may perform real-time monitoring, detection and purification on the cooling liquid.
In other embodiments, the first concentration detection apparatus may also be disposed in a middle section of the liquid inlet pipe.
Specifically, the first concentration detection apparatus 300 is any one of a microwave concentration detector, an ultrasonic concentration detector, a refractive concentration detector, and an infrared concentration detector.
The inventor finds that the infrared concentration detector has better detection precision through experimental research aiming at the cooling liquid of the server.
In an embodiment, the purifying device for the organic liquid includes an alarm module and a control module, the alarm module and the first concentration detecting device 300 are respectively electrically connected with the control module, and the control module controls the alarm module to send an alarm signal according to the concentration value detected by the first concentration detecting device 300. The alarm device is for example an acoustic/optical alarm device.
The control module is, for example, a single-chip microcomputer, a microprocessor, a controller, etc. The control module stores a set value of the concentration of the organic component to be extracted. The concentration value of the organic component to be extracted detected by the first concentration detection means 300 is transmitted to the control module. The control module controls the alarm module to send out an alarm signal according to the concentration value detected by the first concentration detection apparatus 300. In this way, the concentration of the organic component to be extracted can be monitored and managed in real time by the first concentration detection apparatus 300, and the coping strategy can be developed in time.
For example, when the concentration value and the set value are both represented by positive numbers, when the detected concentration value of the organic component to be extracted is lower than the set value, the control module can judge that the pollutant mixed in the organic component to be extracted is out of standard and needs to be purified, so that the control module can control the alarm device to send an alarm signal according to the judging result so as to prompt a worker to timely purify the organic liquid.
In practical use, the concentration value and the set value may be both represented as negative numbers, and when the concentration of the organic component to be extracted is insufficient, the concentration value is higher than the set value. In this case, when the detected concentration value of the organic component to be extracted is higher than the set value, the control module may determine that the pollutant mixed in the organic component to be extracted has exceeded the standard, and the organic liquid needs to be purified, so that the control module may control the alarm device to send an alarm signal according to the determination result.
Referring to fig. 1, in an embodiment, the apparatus for purifying an organic liquid further includes a second concentration detection apparatus 400, where the second concentration detector is used to detect the concentration of the organic component to be extracted in the organic liquid after filtration and before distillation.
Since the concentration of the organic components to be extracted is changed after the organic liquid is filtered out of the solid contaminants, the filtering effect can be judged by detecting the concentration of the organic components to be extracted in the organic liquid after the filtering and before the distillation according to the second concentration detector. If the filtering effect is acceptable, the filtered organic liquid can enter the distillation container 210 to be purified continuously. If the filtering effect is not qualified, further filtering is needed.
Specifically, the second concentration detection apparatus 400 is any one of a microwave concentration detector, an ultrasonic concentration detector, a refractive concentration detector, and an infrared concentration detector.
In an embodiment, the second concentration detection apparatus 400 has a liquid inlet and a first liquid outlet, the liquid inlet of the second concentration detection apparatus 400 is communicated with the outlet of the filtering apparatus, and the first liquid outlet is used for being communicated with the inlet of the distillation apparatus. The second concentration detection apparatus 400 is configured such that the first liquid outlet is opened when the detection result indicates that the filtering effect is acceptable.
When the filtered organic liquid enters the second concentration detection device 400 through the liquid inlet of the second concentration detection device 400, the concentration of the organic component to be extracted in the filtered organic liquid can be detected, so that the filtering effect of the organic liquid can be judged. And when the filtering effect is qualified, the first liquid outlet is opened, so that the filtered organic liquid automatically enters the distillation device from the first liquid outlet to continue purifying. Otherwise, the first liquid outlet is closed, so that the filtered organic liquid cannot enter the distillation device. This ensures that the solid contaminants in the organic liquid are sufficiently filtered out, preventing the solid contaminants from entering the distillation apparatus, and thus avoiding the solid contaminants from being distilled or damaging the heater 220.
As shown in fig. 1, the liquid inlet of the second concentration detection apparatus 400 may be communicated with the outlet of the filtration apparatus through a first communication pipe 410, and the first liquid outlet may be communicated with the inlet of the distillation apparatus through a second communication pipe 420.
In one embodiment, the second concentration detection apparatus 400 has a second liquid outlet for communicating with the filtering apparatus. The organic liquid purifying device further comprises a liquid back-flowing power device 440, wherein the liquid back-flowing power device 440 is used for providing power for the organic liquid flowing into the filtering device from the second liquid outlet. The second concentration detection apparatus 400 is configured such that when the detection result indicates that the filtering effect is not acceptable, the second liquid outlet is opened, and the liquid feedback power apparatus 440 is started. The hydraulic return device 440 is, for example, a hydraulic return pump.
The second concentration detection apparatus 400 is configured such that when the detection result indicates that the filtering effect is not qualified, the second liquid outlet is opened, the liquid return power apparatus 440 is started, so that the power provided by the liquid return power apparatus 440 can enable the organic liquid to flow into the filtering apparatus from the second liquid outlet, and thus the organic liquid can be filtered again, and the filtering effect is further improved by repeated filtration. If the filtering effect is not acceptable after the repeated filtering (for example, three times of filtering), the filtering performance of the filtering piece 120 is insufficient, and the staff can replace the filtering piece in time.
As shown in fig. 1, the second liquid outlet may be communicated with the filtering device through the third communication pipe 430, and the liquid returning device 440 is provided on the third communication pipe 430.
In an embodiment, the organic liquid purifying device further comprises a power device for providing power for the organic liquid flowing into the filtering device and power for the organic liquid flowing from the filtering device into the distillation device, so that the organic liquid can circulate in the organic liquid purifying device.
When the organic liquid purifying device is used for purifying the cooling liquid used in the liquid cooling server, the inlet of the filtering device is communicated with the outlet of the cooling liquid of the server through a pipeline (such as the liquid inlet pipe 130), the outlet of the filtering device is communicated with the inlet of the distilling device through a pipeline, and the outlet of the distilling device is communicated with the inlet of the cooling liquid of the server through a pipeline (such as the liquid outlet pipe 250). In this way, the cooling liquid runs in the server and the purification device of the organic liquid. The cooling fluid is in a flowing state in the server during operation of the server. The power provided by the power device can improve the flowing speed of the organic liquid in the organic liquid purifying device so as to match the flow speed of the cooling liquid in the server, thereby enabling the organic liquid purifying device to stably operate.
Specifically, the first power device 510 may be disposed on the liquid inlet pipe 130 connected to the inlet of the filtering device, and the power provided by the first power device 250 can increase the flow rate of the organic liquid, thereby increasing the flow rate of the organic liquid flowing into the filtering device, and further increasing the overall flow rate of the organic liquid circulating in the organic liquid purifying device. The second power device 520 may also be disposed on a pipe (e.g., the second communication pipe 420) between the outlet of the filtering device and the inlet of the distillation device, so that the power provided by the second power device 520 can increase the flow rate of the organic liquid, thereby increasing the flow rate of the organic liquid flowing into the distillation device, and further increasing the overall flow rate of the organic liquid circulating in the organic liquid purifying device. The power means is for example a pump. The power plant may include a first power plant 510 and/or a second power plant 520.
In an embodiment, the purifying device for organic liquid further comprises a flow detection device for detecting the flow of the organic liquid into the filtering device and/or the flow from the filtering device into the distillation device.
By detecting the flow rate of the organic liquid flowing in the organic liquid purifying device by the flow rate detecting device, the power device can be adjusted according to the detection of the flow rate detecting device, so that the speed of the organic liquid flowing in the organic liquid purifying device can be matched with the flow rate of the cooling liquid in the server.
Specifically, a first flow rate detecting device 610 may be disposed on the liquid inlet pipe 130 connected to the inlet of the filtering device to detect the flow rate of the organic liquid flowing into the filtering device, so that the first power device 510 may be adjusted according to the detection of the first flow rate detecting device 610, so that the flow rate of the organic liquid flowing into the filtering device matches the flow rate of the cooling liquid in the server. A second flow rate detecting means 620 may be provided on a pipe between the outlet of the filtering means and the inlet of the distillation apparatus to detect the flow rate of the organic liquid flowing into the distillation apparatus, so that the second power means 520 may be adjusted according to the detection of the second flow rate detecting means 620 so that the flow rate of the organic liquid flowing into the distillation vessel 210 matches the flow rate of the cooling liquid in the server. The flow rate detection device is, for example, a flow meter.
The filtering piece in the traditional technology is usually made of PP cotton, is easily extracted by liquid pollutants, causes the breakage of the filtering piece, and also causes additional pollution to cooling liquid.
In one embodiment of the present application, the filter 120 is a ceramic membrane element. The ceramic membrane is a semi-permeable membrane, which not only can filter out solid pollutants, but also has selective permeability and only allows ions and small molecular substances to pass through. Therefore, the liquid pollutants with larger molecules can be filtered by utilizing the selective permeability of the semipermeable membrane, so that a better filtering effect is achieved.
The pore diameter of the ceramic membrane element is generally in the micron order or below, and the ceramic membrane element can be divided into a micro-filtration membrane, an ultra-filtration membrane and a nano-filtration membrane according to the difference of the filtration pore diameters (or the size of the molecular weight cut-off). At present, ceramic membrane elements which are formed for industrial scale application mainly comprise ceramic microfiltration membranes and ceramic ultrafiltration membranes, and ceramic nanofiltration membranes with smaller filtration pore size range and higher separation precision are still in the research stage of large-scale preparation technology in China. The material quality of the ceramic membrane determines the physical and chemical properties of the membrane element, and further determines the main performance indexes of hydrophilicity, pollution resistance, high temperature resistance, acid and alkali resistance, thermal stability and the like of the ceramic membrane, so that the ceramic membrane element has better compatibility with cooling liquid (compared with PP cotton). Depending on the material from which the inorganic ceramic film is made, it can be largely classified into alumina (Al 2 O 3 ) Zirconium oxide (ZrO) 2 ) Titanium oxide (TiO) 2 ) Silicon oxide (SiO) 2 ) And ceramic membranes.
Referring to fig. 1, in one embodiment, a first pressure gauge 710 and a first relief vent valve 810 are provided on the filter vessel 110. The first pressure gauge 710 is used for detecting the gas pressure in the filter container 110, the first safety vent 810 is used for preventing the gas pressure in the filter container 110 from being overloaded, and the first safety vent 810 can automatically vent when the set gas pressure is reached in the filter container 110.
Referring to fig. 1, in one embodiment, a second pressure gauge 720 and a second safety vent 820 are provided on the distillation vessel 210. The second pressure gauge 720 is used for detecting the gas pressure in the distillation container 210, the second safety vent 820 is used for preventing the gas pressure in the distillation container 210 from being overloaded, and the second safety vent 820 can automatically vent when the set gas pressure in the distillation container 210 is reached.
An embodiment of the present application further provides a method for purifying an organic liquid, implemented by using the apparatus for purifying an organic liquid according to any one of the embodiments, the method for purifying an organic liquid including the steps of:
s100: the organic liquid is introduced into the filtering device to filter the organic liquid by the filtering device.
S200: the filtered organic liquid flows into a distillation device from a filtering device, and the distillation device distills the filtered organic liquid to separate organic components to be extracted from the organic liquid.
Specifically, the organic liquid in the distillation vessel 210 may be heated by a heating device to vaporize the organic components to be extracted in the organic liquid. The condenser 230 condenses and liquefies the vaporized organic component to be extracted so that the organic component to be extracted enters the collection vessel 240 in liquid form.
In the above method for purifying an organic liquid, the organic liquid is introduced into a filter device to filter solid contaminants in the organic liquid by the filter device. Because the inlet of the distillation device is communicated with the outlet of the filtering device, the filtered organic liquid flows into the distillation device from the filtering device. The distillation device is used for distilling the filtered organic liquid, so that liquid pollutants in the organic liquid can be removed, and organic components to be extracted in the organic liquid can be separated. Namely, the organic liquid purifying device can effectively remove solid and liquid pollutants in the organic liquid and purify the organic liquid.
In an embodiment, the method for purifying an organic liquid further includes, before step S100, detecting a concentration of an organic component to be extracted in the organic liquid upstream of the filtering device using the first concentration detecting device 300. If the detection result indicates that the pollution degree of the organic liquid exceeds the standard, step S100 is executed.
The concentration of the organic components to be extracted in the organic liquid upstream of the filtering device is detected by the first concentration detection device 300, and if the detection result indicates that the pollution degree of the organic liquid exceeds the standard, a worker can start the purification device of the organic liquid in time to purify the organic liquid.
In one embodiment, the method for purifying an organic liquid further includes, before the step of flowing the filtered organic liquid from the filtering device into the distillation device, detecting the concentration of the organic component to be extracted in the filtered organic liquid by using the second concentration detecting device 400.
And if the detection result indicates that the filtering effect is qualified, executing the step of flowing the filtered organic liquid from the filtering device into the distillation device. If the detection result indicates that the filtering effect is not qualified, returning the filtered organic liquid to the filtering device for filtering; alternatively, the filter 120 is replaced.
Since the concentration of the organic components to be extracted is changed after the organic liquid is filtered out of the solid contaminants, the filtering effect can be judged by detecting the concentration of the organic components to be extracted in the organic liquid after the filtering and before the distillation according to the second concentration detector. If the filtering effect is qualified, the filtered organic liquid can enter a distillation device to be purified continuously. If the filtering effect is not qualified, further filtering is needed, so that the organic liquid can be filtered again, and the filtering effect is further improved through repeated filtering. If the filtering effect is not acceptable after the repeated filtering (for example, three times of filtering), the filtering performance of the filtering piece 120 is insufficient, and the staff can replace the filtering piece in time.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
