Example 1
FIG. 1 is a schematic diagram of the overall structure of a sediment separation device according to an embodiment of the present invention; fig. 2 is a cross-sectional view at C-C in fig. 1. Referring to fig. 1 and 2, an embodiment of the present invention provides a sediment separation device 1, wherein the sediment separation device 1 may include a main housing 100, a sediment member 200, and a peeling assembly 300; wherein, the inside of the main casing 100 encloses a reaction chamber, the side wall of the main casing 100 is provided with a plurality of water injection ports 110 for injecting the liquid to be treated, and the bottom of the main casing 100 is provided with a water outlet 120 which can be opened and closed; the deposition piece 200 is movably hung in the reaction chamber to deposit sediment in the liquid to be treated; the stripping assembly 300 includes an impeller 310 rotatably disposed under the deposition member 200, and the impeller 310 is configured to rotate under the impact of the water flow of the water injection port 110 and collide with the deposition member 200 so that the deposits deposited on the deposition member 200 are stripped from the surface of the deposition member 200.
It will be appreciated that the precipitate separating device 1 according to the present invention may be applied to the separation of various types of precipitate in a liquid to be treated. The sediment separation device 1 may for example clean and remove scale from the liquid to be treated, for example clean the liquid to be treated; or collecting the precipitate in the liquid to be treated as a matter to be collected, thereby facilitating the subsequent utilization of the precipitate and the like. Thus, the sediment separation assembly 1 may be used in a variety of different applications, thereby achieving different sediment separation applications. For convenience of explanation, the sediment in the liquid to be treated is taken as scale, and the sediment separation device 1 is mainly used for performing scale removal operation on the liquid to be treated.
Specifically, in the sediment separation device 1 of the present invention, when in implementation, the water injection port 110 may be communicated with the water outlet of the oil-water separation device, the to-be-treated liquid after oil-water separation may flow into the reaction chamber from the water injection port 110, and the to-be-treated liquid flowing into the reaction chamber may be deposited by a period of reaction and may adhere to the surface of the deposition member 200, where the to-be-treated liquid impacts the free end of the deposition member 200 by impacting the impeller 310 of the stripping assembly 300 during the injection into the reaction chamber, so that the sediment such as scale on the deposition member 200 may be removed, and the water after scale removal and the scale after removal may be discharged from the water outlet 120.
Therefore, the sediment separation device 1 provided by the invention can create favorable conditions for the formation of scale, actively consume mineral substances in the liquid to be treated, does not need to use a scale inhibitor, and has low cost.
Second, it should be appreciated that the use of scale inhibitors in the prior art to remove deposits such as scale, in fact, merely inhibit scale formation, does not substantially reduce or eliminate the minerals that result in scale formation, and even the scale inhibitors themselves contain minerals. Thus, when the content of the scale inhibitor injected into the oil layer is insufficient, the inhibiting effect of the scale inhibitor on the formed sediments such as scale and the like is reduced, the oil pipe still faces the scaling problem, and the sediment separating device 1 provided by the embodiment is used for removing the scale or other sediments, so that the mineral content injected into the water layer can be effectively reduced, thereby fundamentally avoiding the formation of the scale sediments and having better cleaning effect on the sediments. In addition, since the process of treating the precipitate using the precipitate separating device 1 provided in the present embodiment may be performed on the ground, it is also convenient to adjust the process of treating the precipitate such as scale by controlling the process conditions to further improve the effect of treating the precipitate.
In practice, the deposition member 200 and the stripping assembly 300 may be installed into the reaction chamber through the drain port 120 at the bottom of the main housing 100, or an installation opening may be formed above the main housing 100, and an installation cover may be disposed at the installation opening, where the deposition member 200 and the stripping assembly 300 may be installed.
In one embodiment, the main housing 100 may be designed as a revolution body, and the plurality of water injection ports 110 are uniformly arranged along the circumferential direction of the main housing 100. Specifically, the main housing 100 may be designed in an inverted kettle shape as shown in fig. 1, i.e., the upper half is cylindrical and the lower half is tapered, so that not only the construction difficulty is reduced, but also the tapered structure of the lower half is convenient for discharging water, scale and other sediments.
The plurality of water injection ports 110 provided on the main housing 100 may be offset from the central axis of the reaction chamber, so that when the plurality of water injection ports 110 simultaneously inject the liquid to be treated into the reaction chamber, a vortex is formed in the reaction chamber, and the vortex may push the impeller 310 of the stripping assembly 300 to rotate. In order to obtain greater power for the impeller 310, the water filling port 110 and the impeller 310 may be located at the same height as much as possible, so that the liquid to be treated flowing into the reaction chamber from the water filling port 110 may directly act on the blades of the impeller 310. Specifically, the plurality of water injection ports 110 may be oriented tangentially to the inner wall of the reaction chamber, and thus the impact force of water injected into the reaction chamber from the water injection ports 110 on the blades of the impeller 310 may be further increased.
FIG. 3 is an enlarged view of FIG. 1 at A; FIG. 4 is a schematic diagram of the overall structure of a sediment separation device according to an embodiment of the present invention; fig. 5 is an enlarged view at B in fig. 4. Referring to fig. 3 to 5, the deposition member 200 may be a hollow steel pipe suspended in the reaction chamber, the bottom of the deposition member 200 may be suspended, specifically, the hanging ring 210 may be movably inserted into the upper end of the deposition member 200, and then one end of the hanging ring 210 away from the deposition member 200 is fixed to the upper end of the main housing 100. It should be understood that the suspended lower end (suspended end) of the depositing member 200 should be partially located between two adjacent blades of the impeller 310, so that when the impeller 310 rotates, the blades of the impeller 310 may collide with the lower end of the depositing member 200 to shake off the deposits such as scale on the depositing member 200.
As shown in fig. 5, in another arrangement of the deposition member 200, the upper end of the deposition member 200 may be a ball-shaped portion 220 fixedly connected, and a ball-shaped receiving groove 230 matched with the ball-shaped portion 220 may be provided on the top wall of the reaction chamber such that the ball-shaped portion 220 is caught in the ball-shaped receiving groove 230, and when the lower end of the deposition member 200 is collided with the impeller 310, the ball-shaped portion 220 of the upper end of the deposition member 200 may freely rotate in the ball-shaped receiving groove 230. Further, a stopper 240 may be further provided at the junction of the spherical portion 220 and the spherical receiving groove 230, and the stopper 240 may be used to prevent the spherical portion 220 from being separated from the spherical receiving groove 230. The deposition member 200 may be provided in other arrangements, without limitation.
In one embodiment, a plurality of through holes may be further formed on the sidewall of the deposition member 200, so that the surface area of the deposition member 200 may be increased to increase the deposition rate of the deposition of the scale, etc. on the deposition member 200.
In addition, there may be a plurality of deposition members 200, and a plurality of deposition members 200 may be disposed at intervals. By increasing the number of deposition pieces 200, the overall surface area of the deposition pieces 200, i.e., the deposition area, can be increased, and the efficiency of the treatment of the deposits such as scale can be improved.
The stripping assembly 300 may further include a rotation shaft 320, and when the stripping assembly is implemented, one end of the rotation shaft 320 may be vertically disposed and connected to the upper end of the main housing 100, and the impeller 310 may be mounted to the lower end of the rotation shaft 320. Specifically, the impeller 310 may be directly welded to the lower end of the rotation shaft 320, and the upper end of the rotation shaft 320 may be connected to the upper end of the main housing 100 through a bearing 330. In order to improve the stability of rotation of the impeller 310, the length of the connection section of the upper end of the rotation shaft 320 to the upper end of the main casing 100 may be appropriately increased, for example, may be connected to the upper end of the main casing 100 through a plurality of bearings 330 axially provided along the rotation shaft 320.
In one embodiment, the sediment separation assembly 1 may further include a driving motor having an output shaft connected to the rotation shaft 320. Specifically, the driving motor may be disposed on an outer surface of an upper end of the main housing 100, and an upper end of the rotation shaft 320 is penetrated out of the upper end of the main housing 100, so that the rotation shaft 320 penetrated out of the main housing 100 is fixedly connected with an output shaft of the driving motor. In this way, the peeling assembly 300 can be driven to rotate by the driving motor, so that the deposits such as scale on the deposition member 200 can be peeled at any time. And the driving motor drives the stripping assembly 300 to rotate with more sufficient power, so that the stripping effect of the sediment on the deposition member 200 can be improved.
In one embodiment, a heat exchange member may be further provided along the circumference of the outer wall of the main housing 100, wherein the heat exchange member is used to exchange heat with the main housing 100 to increase or decrease the temperature of the main housing 100.

Specifically, the heat exchange member may be an electric heating wire wound on the outer wall of the main housing 100, and heating is convenient and efficient by the electric heating wire. The electrothermal exchange element may also be a heat exchanger, such as a water heating pipe, a gas heating pipe, a water cooling pipe or a gas cooling pipe, disposed along the outer wall of the main casing 100, and the heat exchanger is used to change the temperature of the main casing 100, so that the electrothermal exchange element is safe and reliable.
It should be noted that, in the embodiment of the present application, a plurality of precipitate separation devices 1 may be provided, and the plurality of precipitate separation devices 1 may be communicated with the outlet of the oil and water homogenizing separation device through a multi-directional valve, so that when the liquid to be treated in one of the precipitate separation devices 1 is fully loaded, the multi-directional valve may be controlled to inject water into the other precipitate separation device 1, thereby further improving the efficiency of treating the precipitate such as scale.
In one embodiment, the precipitate separation device 1 is further provided with a feeding port, specifically, the feeding port may be disposed at the top of the main casing 100, and the feeding port may be conveniently used to add substances capable of accelerating the scaling process into the reaction chamber.

As shown in fig. 6, the present invention also provides a sediment separation method which can be applied to the sediment separation device of any one of the first embodiments, thereby removing sediment such as scale in the liquid to be treated. The precipitate separation method may include:
s100, enabling a water outlet of the sediment separation device to be kept in a closed state, and injecting liquid to be treated into a reaction chamber of the sediment separation device through a water injection port of the sediment separation device.
And S200, continuously reacting for a preset time to enable sediment to be deposited on a deposition piece in the sediment separation device.
The formation of the precipitate can be accelerated by adding the scaling agent into the liquid to be treated in the reaction chamber, the precipitate can be gradually deposited on the surface of the deposition piece, and the preset time can be controlled to be 1-5 h, so that the reaction is not thorough enough due to the too short reaction time, the efficiency is not reduced due to the too long reaction time, and the preset time can be 3h.
S300, opening the water outlet, and injecting water without sediment into the reaction chamber again, so that the impeller of the stripping assembly collides with the sediment piece under the action of water flow, and the sediment is stripped from the sediment piece and discharged from the water outlet.
The water without sediment can be clean water which does not flow into the stratum or water treated by the sediment separation device. Fig. 7 is a schematic diagram of a sediment treatment method according to an embodiment of the present invention, as shown in fig. 7, specifically, water and sediment discharged from a water outlet may be collected in a water tank for solid-liquid separation (for example, the sediment may be settled at the bottom of the water tank to separate the water and the sediment), the separated water in the water tank may be pumped out by a water pump and injected into a water storage device, the water entering the water storage device may be reused and injected into a reaction chamber through a water filling port, or the water in the water storage device storing clean water may be directly injected into the reaction chamber to drive an impeller to rotate.
It should be understood that when the water outlet is opened and water without sediment is injected into the reaction chamber, the water without sediment entering the reaction chamber from the water injection port forms vortex to drive the stripping assembly to rotate, the impeller of the stripping assembly collides with the lower end of the deposition member, so that the sediment is separated from the surface of the deposition member, and when the sediment is separated from the deposition member, water injection into the reaction chamber can be stopped.
In addition, because the reaction chamber is already stored with the liquid to be treated, when the reaction chamber is filled with water again, the water inlet can face a certain water pressure, at this time, the pressure during water injection can be properly increased to overcome the water pressure at the water inlet in the reaction chamber, and meanwhile, the force of the impeller when the impeller collides with the deposition piece can be increased, the time for stripping the sediment on the deposition piece is shortened, and the sediment treatment efficiency is improved.
It should be understood that in this step, even if the precipitate on the deposition member is not completely peeled off, the precipitate remaining on the deposition member can be peeled off by continuing the method of colliding with the deposition member when the liquid to be treated is injected into the reaction chamber next time.
In addition, after the water and the sediment in the reaction chamber are discharged from the water outlet, the reaction chamber can be optionally washed by using the water without the sediment, or the water can directly enter the next round of sediment treatment, the treatment method can be consistent with the sediment treatment method in the embodiment, and the sediment treatment method in the embodiment is repeated until all the water containing the sediment is treated at least once by the sediment separation device.
In this embodiment, the fouling process can also be accelerated by adjusting the reaction chamber temperature through heat exchange elements or by adding substances to the reaction chamber that assist in the fouling process, as desired.
The sediment treatment method provided by the embodiment has the advantages that the sediment separation device provided by the embodiment I is used, the cost is lower, and the sediment removal effect is better.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
