Detailed Description
The following examples are given for the detailed implementation and the specific operation procedures of the present invention, but the scope of the present invention is not limited to the following examples.
In the description of the present invention and embodiments, it is to be understood that the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
In the description of the present invention and the embodiments thereof, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, are only used for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or component parts referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, in a first embodiment of the present invention, a liquid separator is provided, which includes a housing 101, a partition plate 102 and a first porous packing 105, wherein the partition plate 102 is disposed in the housing 101 to divide the housing 101 into a first chamber 103 and a second chamber 104, the bottom of the first chamber 103 is communicated with the bottom of the second chamber 104, and the first porous packing 105 is filled at the communication position of the bottom of the first chamber 103 and the bottom of the second chamber 104.
The first porous filler 105 may be, for example, a stainless steel mesh, an asbestos mesh, or the like.
The partition plate 102 only needs to divide the housing 101 into two chambers, i.e., a left chamber and a right chamber, and the partition plate 102 may be disposed vertically, as shown in fig. 1, or disposed obliquely, which is not limited in this application.
When the liquid separator is used, the liquid to be separated can enter the first chamber 103 from the liquid inlet 130, and part of oil drops and other polluting substances in the liquid to be separated gradually float to the liquid surface of the distilled water layer 140 in the first chamber 103 due to the density of the liquid to be separated being lower than that of the distilled water, so that the suspension layer 150 is formed. Meanwhile, the liquid to be separated enters the first porous packing 105, and the other part of fine oil droplets and other polluting substances are gathered and enlarged in the first porous packing 105, and gradually float to the liquid surface of the distilled water layer 140 in the first chamber 103 to join with the original suspension layer 150. Due to the presence of the baffle 102, oil droplets and other contaminating substances in the liquid to be separated are collected on the surface of the distilled water in the first chamber 103, while the second chamber 104 is almost free of oil droplets and other contaminating substances.
In the liquid separator of the present embodiment, since the partition plate 102 divides the housing 101 into two chambers, the thickness of the suspension layer 150 formed in the first chamber 103 is thicker, and thus separation is more easily achieved, compared to a conventional liquid separator of the same shape and size. Meanwhile, there are almost no oil drops and other polluting substances in the second chamber 104, so the distilled water discharged from the second chamber 104 is cleaner and the separation effect of the liquid separator is better.
Optionally, the water outlet 120 of the liquid separator is disposed on the sidewall of the second chamber 104, and the height of the water outlet 120 is higher than the height of the bottom end of the partition plate 102, so as to ensure that the water flow passes through the whole first porous packing 105 better, and further ensure the cleanliness of the outlet water.
Optionally, referring to fig. 2, a first liquid level sensor 106 is disposed in the first chamber 103, a second liquid level sensor 107 is disposed in the second chamber 104, and a height of the first liquid level sensor 106 is higher than a height of the second liquid level sensor 107; the first chamber 103 is also connected to a first suction line 108 and a second suction line 109, the suction port 1081 of the first suction line is lower than the first level sensor 106 and higher than or equal to the second level sensor 107, and the suction port 1091 of the second suction line is lower than the second level sensor 107.
The first level sensor 106 and the second level sensor 107 described above are triggered when the liquid level reaches the respective set height.
In the embodiment, it is assumed that the height of the first liquid level sensor 106 relative to the bottom of the casing 101 is H1, the height of the second liquid level sensor 107 relative to the bottom of the casing 101 is H2, the height of the suction port 1081 of the first suction line relative to the bottom of the casing 101 is H3, and the height of the suction port 1091 of the second suction line relative to the bottom of the casing 101 is H4, as shown in fig. 3, H1 > H3 ≧ H2 > H4.
The specific height difference between the first liquid level sensor 106, the suction port 1081 of the first pumpback line, the second liquid level sensor 107 and the suction port 1091 of the second pumpback line can be determined according to actual conditions. For example, the heights of the suction ports 1081 and 1091 of the first and second evacuation lines can be adjusted to adjust the specific height difference according to the densities of different types of aerosol layers.
Since the bottoms of the first chamber 103 and the second chamber 104 are connected, the pressure at the top is the same, and therefore the pressure of the liquid in the first chamber 103 and the pressure of the liquid in the second chamber 104 are equal to each other at the bottoms. By using the U-tube density difference principle, assuming that the density of water is ρ 1, the density of suspended matter is ρ 2, the gravitational acceleration is g, the height of the distilled water layer in the first chamber 103 is Hb, the height of the suspended matter layer is Hc, and the height of the distilled water in the second chamber 104 is Ha, the pressure of the liquid can be obtained by the formula:
ρ1gHa＝ρ1gHb+ρ2gHc，
namely: ρ 1Ha = ρ 1Hb + ρ 2Hc.
Ha < Hb + Hc, since the density of water is greater than the density of the suspension, i.e. p 1 > p 2.
Taking Δ H = Hb + Hc-Ha, it is clear that the value of Δ H is also greater when the thickness Hb of the suspension layer is greater.
Referring to FIG. 4, when the second level sensor 107 is activated and the first level sensor 106 is not activated, it is illustrated that the height of the distilled water layer plus the height of the suspension layer Hb + Hc in the first chamber 103 is less than H1, i.e., H1 > (Hb + Hc); while the height Ha of the distilled water layer in the second chamber 104 is equal to H2, i.e. H2= Ha. Therefore, (H1-H2) > (Hb + Hc-Ha) = Δ H. It can be seen that at this time, the thickness of the suspension layer in the first chamber 103 is relatively thin, the first pumping-back line 108 is activated, and since H1 > H3 ≧ H2, the first pumping-back line 108 can pump back the liquid layer whose height is greater than or equal to H3.
Referring to fig. 5, when the first liquid level sensor 106 and the second liquid level sensor 107 are triggered simultaneously, it is illustrated that the height of the distilled water layer in the first chamber 103 plus the height Hb + Hc of the suspension layer is equal to H1, i.e., (Hb + Hc) = H1; meanwhile, the height Ha of the distilled water layer in the second chamber 104 is equal to H2, that is, ha = H2. Thus, Δ H = (H1-H2). It can be seen that, at this time, the thickness of the suspension layer in the first chamber 103 is relatively thick, the second evacuation line 109 can be activated, and since H1 > H4, the second evacuation line 109 can evacuate liquid layers having a height higher than and equal to H4.
Referring to fig. 6, when the first liquid level sensor 106 is triggered and the second liquid level sensor 107 is not triggered, it is illustrated that the height of the distilled water layer in the first chamber 103 plus the height Hb + Hc of the suspension layer is equal to H1, i.e., (Hb + Hc) = H1; meanwhile, the height Ha of the distilled water layer in the second chamber 104 is less than H2, i.e., ha < H2. Therefore,. DELTA.h > (H1-H2). It can be seen that at this point, the layer of suspension in the first chamber 103 is relatively thick, and the second evacuation line 109 can be activated, so that the liquid layer having a height greater than or equal to H4 can be evacuated back, since H1 > H4. Preferably, the first and second evacuation lines 108 and 109 can be activated at the same time to evacuate the liquid layer with a height higher than or equal to H4 more quickly, further reducing the risk of volatile substances in the suspension layer volatilizing into gas and being discharged into the atmosphere, and further reducing the risk of remixing of the suspension layer with distilled water.
By adopting the liquid separator in this embodiment, the suspended matter in the first chamber 103 can be pumped back, on one hand, volatile substances in the suspended matter layer can be prevented from being emitted into gas, and the exhaust system can cause pollution to the atmosphere; on the other hand, the method avoids the polluting substances in the suspension layer from staying in the liquid separator for a long time and mixing with the distilled water again to form a mixture which is difficult to separate, and the quality of the distilled water discharged from the liquid separator is influenced. Meanwhile, by adopting the liquid separator in this embodiment, distilled water separated from the condensed liquid can be pumped back as little as possible while the suspension layer is pumped back, improving the treatment efficiency of the liquid separator.
Optionally, referring to fig. 7 to 9, the liquid separator further includes an expanding pipe 110 communicated with the first chamber 103 and used for introducing the liquid to be separated, a pipe diameter of one end 111 of the expanding pipe is larger than that of the other end 112, and the end 111 with the larger pipe diameter is connected with the first chamber 103.
In use, the liquid to be separated may have already been subjected to separation by other separation means before being passed to the liquid separator. For example, in an MVR evaporation system, referring to fig. 10, the liquid separator 100 may be in communication with the liquid outlet 203 of the MVR evaporator 200. The liquid to be separated is firstly subjected to evaporation separation by the MVR evaporator 200, so that most of the polluting substances such as solvents, oils and the like are separated from the water, and a small amount of the polluting substances such as volatile substances, oil droplets and the like are released heat and condensed in the shell pass 202 of the MVR evaporator 200 and then enter the liquid separator 100 together with distilled water through the liquid outlet 203 of the MVR evaporator. At this moment, adopt divergent pipe 110 to connect MVR evaporimeter liquid outlet 203 and first cavity 103, can let and keep the natural gentle flow under the effect of gravity from waiting to separate and enter into first cavity 103 and separate to avoid the disturbance that rapid flow caused, make distilled water and polluting substances mix, and then be favorable to liquid separator's separation.
Alternatively, the height of the second liquid level sensor 107 may be equal to the lowest point where the divergent pipe 110 and the first chamber 103 communicate with each other, or slightly lower than the height of the divergent pipe 110 at the interface with the first chamber 103. The first level sensor 106 may be positioned at a height slightly greater than the height of the second level sensor 107.
Alternatively, referring to fig. 8, the diverging pipe 110 may be a inclined pipe 118 whose pipe diameter gradually decreases from one end 111 to the other end 112. The inclined pipe in the embodiment of the application refers to a pipeline with the pipe diameter gradually increasing or decreasing.
Referring to fig. 7 and 9, the divergent pipe 110 may further include at least one straight pipe 117 and at least one inclined pipe 118, the straight pipe 117 is connected to the inclined pipe 118 at intervals, and an aperture of one end of the inclined pipe 118 is the same as an aperture of the straight pipe 117 connected to the inclined pipe 118 adjacently. In contrast, the height of the bottom of the straight tube 117 or the inclined tube 118 relatively close to the first chamber 103 is not higher than the height of the bottom of the straight tube 117 or the inclined tube 118 relatively far from the liquid outlet 203, so that the distilled water and the polluting substances can flow under the action of gravity. The divergent tube 110 formed by connecting the straight tube 117 and the inclined tube 118 at intervals can reduce the flow rate of the distilled water and the polluting substances, so that the distilled water and the polluting substances can flow more stably and gently, further, the distilled water and the polluting substances are prevented from being mixed in the continuous acceleration flow process, the separation of a liquid separator is facilitated, and the quality of separated water is further improved.
Optionally, referring to fig. 7 to fig. 9, the first baffle 113 is fixedly connected to the top of the divergent pipe 110, and a gap 116 is formed between the bottom of the first baffle 113 and the bottom of the divergent pipe 110. A second baffle plate 114 is further fixedly connected to the top of the interior of the divergent tube 110, a gap 116 is formed between the bottom end of the second baffle plate 114 and the bottom of the divergent tube 110, and a second porous filler 115 is filled in the divergent tube between the first baffle plate 113 and the second baffle plate 114. The size of the gap 116 between the first baffle 113 and the bottom of the divergent pipe 110, the second baffle 114 and the bottom of the divergent pipe 110 can be adjusted according to practical situations, which is not limited in this application. The second porous filler 115 may be, for example, a wire mesh, organic cotton, or the like.
Referring to fig. 10, when the liquid separator is applied to an MVR evaporation system and is communicated with the liquid outlet 203 of the MVR evaporator, there may be uncondensed gas in the shell side 202 of the MVR evaporator, and most of the gas is discharged from the gas exhaust pipeline 400, but a small part of the gas enters the divergent pipe 110 through the liquid outlet 203 and then enters the shell 101 of the liquid separator. These gases, on the one hand, agitate the distilled water and the polluting substances which are originally in a natural, gentle flow; on the other hand, since the top of the first chamber 103 and the top of the second chamber 104 are also connected in a normal condition, volatile gas and fine oil droplets in the gas directly enter the first chamber 103 and the second chamber 104 to be condensed, aggregated and re-dissolved, and continuously pollute the distilled water which is originally separated in the second chamber 104.
In the present embodiment, since the bottom end of the first baffle 113 is higher than the bottom of the divergent pipe 110, a gap 116 exists between the bottom end of the first baffle 113 and the bottom of the divergent pipe 110. Distilled water and contaminants continue to flow smoothly through the diverging tube 110 and continue to flow smoothly into the liquid separator through the gap 116. The volatile gas and oil droplets in the gas in the shell side 202 are blocked to some extent by the first baffle 113, and the gas entering the liquid separator through the divergent pipe 110 is reduced, so that the risk of contamination of the distilled water in the second chamber 104 by the volatile gas and oil droplets in the gas is reduced.
Further, by arranging two baffles and filling the second porous filler 115 in the divergent pipe 110 between the baffles, fine liquid droplets in the gas are further captured by the second porous filler 115, so as to better prevent the fine liquid droplets from entering the second chamber 104, and simultaneously, the water flow flowing to the first chamber 103 through the divergent pipe 110 is more uniform and gentle.
Referring to fig. 10, in a second embodiment of the present application, an MVR evaporation system is provided, which includes an MVR evaporator 200, a vapor compressor 500, and any one of the liquid separators 100 described above, wherein a tube side 201 of the MVR evaporator is connected to an air inlet of the vapor compressor 500, a shell side 202 of the MVR evaporator is connected to an air outlet of the vapor compressor 500, and a liquid outlet 203 of the MVR evaporator is connected to the first chamber 103 of the liquid separator 100; the second chamber 104 of the liquid separator 100 is provided with a water intake 160, and the water intake 160 is communicated with an air inlet of the vapor compressor 500. Preferably, the intake port 160 opens at the bottom of the second chamber 104. The distilled water in the second chamber 104 may also exit the liquid separator 100 through a water outlet 120 disposed in a sidewall of the second chamber 104.
When in use, a gas-liquid separator 600 communicated with the tube pass 201 of the MVR evaporator can be arranged above the MVR evaporator 200 to remove most of liquid drops and foams in the vapor generated by evaporation in the tube pass 201. An exhaust pipeline 400 can be further arranged in the MVR evaporation system, and the exhaust pipeline 400 is communicated with the shell side 202 and is used for exhausting gas which is not condensed in the shell side 202. Preferably, the exhaust pipeline 400 and the air inlet pipeline 700 are respectively disposed on two opposite sides of the sidewall of the MVR evaporator 200, so that the high-quality steam entering the shell side 202 from the air inlet pipeline 700 is fully heat-exchanged with the heat exchange pipe, and then is exhausted from the exhaust pipeline 400 to enter the subsequent processing step of the gas.
In operation, the liquid to be treated enters the tube pass 201 from the liquid inlet cavity 204 at the bottom of the MVR evaporator 200, and is heated and evaporated in the tube pass 201. During the evaporation process, volatile solvent gas, pollutant gas and other pollutant gases, and oil droplets, pollutant droplets and other pollutant droplets are mixed in the water vapor, and most of the droplets and bubbles in the steam generated by evaporation in the tube pass 201 are removed through the gas-liquid separator 600. And then compressed by a vapor compressor 500 to become high quality vapor, which enters the shell side 202. The high-quality steam in the shell pass 202 exchanges heat with the liquid in the tube pass 201 to maintain the heat required by the evaporation of the liquid in the tube pass 201; meanwhile, the steam in the shell side 202 is condensed into condensate after heat exchange. The condensate enters the first chamber 103 of the liquid separator 100 through the liquid outlet 203 of the MVR evaporator and is separated into layers to remove distilled water from the second chamber 104. The water intake 160 of the liquid separator 100 is communicated with the air inlet of the vapor compressor 500 through the cooling water pipeline 300, and clean distilled water is used as cooling water to control the temperature of the vapor compressor 500, so that the condition that the vapor compressor 500 is unstable to cause the change of the working condition of the whole MVR evaporation system is prevented, and the cyclic utilization of the distilled water is realized. The water intake 160 is disposed at the bottom of the second chamber 104, so that clean distilled water can be taken out, and the cooling water can be prevented from being deficient to the greatest extent.
In addition, the MVR evaporation system has better effluent quality and higher cleaning degree, and the MVR evaporation system includes any one of the liquid separators, so the MVR evaporation system also has the beneficial effects of the liquid separator in the embodiments, and the description is omitted here.
Still referring to fig. 10, in a third embodiment of the present application, an MVR evaporation system is provided, which includes an MVR evaporator 200, a vapor compressor 500 and any of the liquid separators 100 described above, wherein a tube side 201 of the MVR evaporator is communicated with an air inlet of the vapor compressor 500, a shell side 202 of the MVR evaporator is communicated with an air outlet of the vapor compressor 500, and a liquid outlet 203 of the MVR evaporator is communicated with the first chamber 103 of the liquid separator 100; both the first withdrawal line 108 and the second withdrawal line 109 of the liquid separator 100 are in communication with the tube side 201 of the MVR evaporator.
When in use, a gas-liquid separator 600 communicated with the tube pass 201 of the MVR evaporator can be arranged above the MVR evaporator 200 to remove most of liquid drops and foams in the steam generated by evaporation in the tube pass 201. The first and second withdrawal lines 108 and 109 are both in communication with the tube side 201 of the MVR evaporator via a gas-liquid separator 600. The gas inlet of the vapor compressor 500 is also in communication with the tube side 201 of the MVR evaporator via a vapor-liquid separator 600.

And then compressed by a vapor compressor 500 to become high quality vapor entering the shell side 202. The high-quality steam in the shell pass 202 exchanges heat with the liquid in the tube pass 201 to maintain the heat required by the evaporation of the liquid in the tube pass 201; meanwhile, the steam in the shell side 202 is condensed into condensate after heat exchange. The condensate enters the first chamber 103 of the liquid separator 100 through the liquid outlet 203 of the MVR evaporator, and is separated by layers to remove clean distilled water from the second chamber 104. The layer of suspension suspended on the surface of the liquid in the first chamber 103 is re-sucked into the tube side 201 of the MVR evaporator via the first and second evacuation lines 108, 109.
Because the tube pass 201 of the MVR evaporator is under negative pressure when the MVR evaporation system works, as long as the valves on the first and second pumping back pipelines 108 and 109 are opened, the suspension layer higher than the respective suction ports of the two pumping back pipelines will be sucked into the tube pass 201 of the MVR evaporator again, and no other power is needed to start the pumping back pipeline. Through with the suspension layer back suction tube side 201, can also prevent that the volatile substance in the suspension layer from volatilizing, prevent that the volatile gas in the liquid separator 100 from discharging MVR evaporation system, cause the pollution to the atmosphere.
In addition, the MVR evaporation system has better effluent quality and higher cleaning degree, and the MVR evaporation system includes any one of the liquid separators, so the MVR evaporation system also has the beneficial effects of the liquid separator in the embodiments, and the description is omitted here.

if the second level sensor 107 is triggered and the first level sensor 106 is not triggered, the first pumpback line 108 is activated;
if the first liquid level sensor 106 and the second liquid level sensor 107 are both triggered, the second pumping-back pipeline 109 is started;
