Description

Technical Field

[0001] The present invention relates to the technical field of epoxy dust removal equipment, and particularly to a powder dust removal device for epoxy processing. Background Art

[0002] Epoxy powder is a thermosetting and non-toxic coating. After curing, it forms a high-molecular-weight cross-linked structure coating, which has excellent chemical corrosion resistance and relatively high mechanical properties, especially the best wear resistance and adhesion. In the prefabrication operation of oilfield surface pipelines in factories, it is necessary to separate the dust, solid particles and sprayed epoxy powder particles generated by shot blasting rust removal and peening rust removal through a dust removal system.

[0003] In the dust removal device, since the flow rate of the dust-containing gas introduced is inconsistent, the density of the bubbles generated when the gas is introduced into the device is different. When the flow rate of the dust-containing gas introduced increases, the density of the generated bubbles will increase, which may cause the bubbles in the separation liquid to aggregate and increase with each other, resulting in a decrease in the specific surface area of the gas per unit volume of the bubbles, a decrease in the contact area with the separation liquid, a reduction in the mass transfer efficiency between the bubbles and the separation liquid, and a reduction in the adsorption effect and utilization rate of the separation liquid. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a powder dust removal device for epoxy processing, including a separation liquid input pipe. An outer wall of the separation liquid input pipe is fixedly connected with a tank body shell. An outer wall of the tank body shell is fixedly connected with a separation liquid output pipe. The device further includes:

[0005] An input mechanism, which is fixedly connected to an inner wall of the tank body shell and is used to limit the size and input position of the bubbles input into the tank body;

[0006] An isolation mechanism, which is fixedly connected to an outer wall of the tank body shell and is used to reduce the escape of the particulate gas in the cavity;

[0007] A floating mechanism, which is fixedly connected to an inner wall of the isolation mechanism and is used to change the position of the device according to the liquid level position;

[0008] An inner tank body is fixedly connected to an inner wall of the tank body shell. A plurality of limiting holes are formed in a bottom of the inner tank body. A slide rail is fixedly connected to an outer wall of the bottom of the inner tank body.

[0009] When the dust-containing gas increases due to factors such as gas flow rate, the generated bubbles gradually approach the separation liquid input pipe. Since the diameter of the separation liquid input pipe is larger than that of the inner tank body, the flow rate of the separation liquid at the separation liquid input pipe is larger than that of the separation liquid inside the inner tank body. Since the generated bubbles enter the separation liquid from below, when the generated bubbles are closer to the separation liquid input pipe, the bubbles will increase the distance of flow along with the separation liquid, so that the contact time between the bubbles and the separation liquid will increase, thereby improving the mass transfer efficiency between the bubbles and the separation liquid, and improving the utilization rate of the separation liquid and the effect of adsorbing particles.

[0010] Preferably, the input mechanism includes:

[0011] A fixing component, the outer wall of which is fixedly connected to the inner wall of the tank shell;

[0012] A sliding component, the outer wall of which is fixedly connected to the outer wall of the fixing component.

[0013] Preferably, the isolation mechanism includes:

[0014] A driving component, the outer wall of which is fixedly connected to the inner wall of the tank shell;

[0015] A pump body component, the outer wall of which is slidably connected to the inner wall of the driving component.

[0016] Preferably, the floating mechanism includes:

[0017] An isolation component, the outer wall of which is fixedly connected to the inner wall of the driving component;

[0018] A floating component, the outer wall of which is fixedly connected to the outer wall of the isolation component.

[0019] Preferably, the fixing component includes a slider slidably connected to the outer wall of the slide rail. The outer wall of the slider is fixedly connected with a sliding cavity, and a plurality of output holes are provided on the inner wall of the sliding cavity.

[0020] Due to factors such as the different flow rates of the dust-containing gas input, the pressure exerted by the dust-containing gas on the sliding cavity is different. When the flow rate of the dust-containing gas increases, the bubble density passing through the restriction hole increases, which may cause bubble aggregation, reduce the contact area between the bubbles and the separation liquid, and lower the mass transfer efficiency. At this time, since the aperture of the restriction hole gradually decreases and the density gradually increases from the sliding cavity to the separation liquid input pipe, when the flow rate of the dust-containing gas increases, the sliding cavity will gradually move towards the separation liquid input pipe, so that the output hole will communicate with the gradually decreasing restriction hole, and the sliding cavity where the output hole is not opened will block the larger restriction hole far from the separation liquid input pipe, making the dust-containing gas passing through the output hole can only enter the inner tank through the smaller and denser restriction holes, thus reducing the volume of the bubbles generated by the dust-containing gas entering the separation liquid in the inner tank, improving the mass transfer efficiency between the dust-containing gas and the separation liquid and the utilization rate of the separation liquid;

[0021] Preferably, the sliding component includes a partition fixed to the inner wall of the bottom of the tank shell, several reset springs are fixedly connected to the outer wall of the sliding cavity, and two gas input cavities are provided on the inner walls of both sides of the inner tank, and two gas input pipes are fixedly connected to the inner walls of the two gas input cavities.

[0022] During use, first input the separation liquid from the separation liquid input pipe to reach the inside of the tank shell. When there is separation liquid inside the inner tank, input the dust-containing gas into the gas input cavity from the gas input pipe. At this time, as the input dust-containing gas gradually increases, the space between the partition and the sliding cavity will be filled with the dust-containing gas. At this time, the output hole is blocked by the outer wall of the inner tank, making the dust-containing gas unable to escape, so that the dust-containing gas pushes the sliding cavity towards the separation liquid input pipe. As the sliding cavity gradually moves, when the output hole reaches the restriction hole with the movement of the sliding cavity, the dust-containing gas will enter the inside of the inner tank through the restriction hole. Since the inside of the inner tank is full of separation liquid at this time, the dust-containing gas passing through the restriction hole will enter the separation liquid in the form of bubbles;

[0023] Preferably, the driving component includes a gas output pipeline fixed to the inner wall of the tank shell, several connecting rods are fixedly connected to the inner wall of the gas output pipeline, one end of the several connecting rods far from the inner wall of the gas output pipeline is rotatably connected to a rotating shaft, and an impeller is fixedly connected to the outer wall of the rotating shaft.

[0024] After the device has been running for a period of time, due to the gradual increase in the pressure of the dust-containing gas, a cavity will be formed in the upper space inside the inner tank. At this time, the bubbles reaching the liquid surface in the separation liquid will burst, causing the dust particles that have not been mixed with the separation liquid inside the bubbles to enter the cavity. At this time, the gas that has come into contact with the separation liquid will escape from the gas output pipe, and the escape of the gas will drive the impeller to rotate. The rotation of the impeller will drive the connecting plate to rotate together. At this time, several bearings arranged on the outer wall of the connecting plate will rotate around the rotating shaft under the drive of the connecting plate;

[0025] Preferably, the pump body assembly includes two sliding grooves opened on the outer wall of the rotating shaft. The inner walls of the two sliding grooves are slidably connected with a connecting plate, and several bearings are rotatably connected to the outer wall of the connecting plate.

[0026] Preferably, the isolation assembly includes several guide rods fixedly connected to the inner wall of the gas output pipe. The outer walls of the several guide rods are slidably connected with a fixing plate. A corrugated pipe is fixedly connected to the outer wall of the fixing plate, and a flexible pipe is fixedly connected to the inner wall of the fixing plate.

[0027] Preferably, the floating assembly includes a spraying cavity fixedly connected to the inner wall of the corrugated pipe. Several spraying ports are opened on the outer wall of the spraying cavity, and several floating cylinders are fixedly connected to the outer wall of the fixing plate;

[0028] The inner wall of the spraying port is rotatably connected to the outer wall of the rotating shaft.

[0029] The movement of the bearing will squeeze the flexible pipe, causing the separation liquid inside the flexible pipe to flow towards the inside of the spraying cavity. When the spraying cavity is filled with the separation liquid inside, as the bearing continues to move, the separation liquid inside the spraying cavity will be sprayed out of the spraying cavity through the spraying port. Since the aperture of the spraying port is small and dense, the separation liquid sprayed out therefrom will form a mist curtain, mixing the dust that has not been mixed with the separation liquid through the mist curtain. The mixture after mixing has a large mass, so that the gas cannot drive it to escape through the gas output pipe, reducing the amount of dust escaping through the gas output pipe, increasing the mixing amount of dust and separation liquid, and improving the utilization rate of the separation liquid;

[0030] When the separation liquid inside the inner tank changes in the level position due to the increase in gas pressure or other factors, causing the isolation assembly to be unable to contact the separation liquid, at this time, several floating cylinders arranged on the outer wall of the fixing plate will change accordingly with the change of the liquid level, so that the flexible pipe can contact the separation liquid in time, reducing the probability that the separation liquid inside the spraying cavity cannot be replenished due to the change in the position of the separation liquid level, and further reducing the probability of dust escaping from the gas output pipe, improving the utilization rate of the separation liquid and the effect of the separation liquid adsorbing particles.

[0031] The present invention has the following beneficial effects:

[0032] (1) To solve the problem that when the flow rate of the dust-containing gas introduced increases, the generated bubbles are too dense, resulting in a decrease in mass transfer efficiency, the present invention is provided with an input mechanism. Since the aperture of the restricted hole gradually decreases and the density gradually increases from the sliding cavity to the separation liquid input pipe, when the flow rate of the dust-containing gas increases, the sliding cavity will gradually move towards the separation liquid input pipe, so that the output hole will communicate with the gradually decreasing restricted hole, and the sliding cavity without the output hole will block the larger restricted hole away from the separation liquid input pipe, so that the dust-containing gas passing through the output hole can only enter the inner tank through the smaller and denser restricted holes, thus reducing the volume of the bubbles generated by the dust-containing gas entering the separation liquid in the inner tank, increasing the specific surface area of the gas per unit volume of the bubbles, increasing the contact area with the separation liquid, and improving the mass transfer efficiency between the dust-containing gas and the separation liquid and the utilization rate of the separation liquid;

[0033] (2) To solve the problem that the low contact time between the bubbles and the separation liquid results in a decrease in the mass transfer efficiency between the bubbles and the separation liquid, the present invention is provided with a sliding component. When the dust-containing gas increases due to factors such as gas flow rate, the generated bubbles gradually approach the separation liquid input pipe. Since the diameter of the separation liquid input pipe is larger than the diameter of the inner tank, the flow rate of the separation liquid at the separation liquid input pipe is larger than the flow rate of the separation liquid inside the inner tank. Since the generated bubbles enter the separation liquid from below, when the generated bubbles are closer to the separation liquid input pipe, the bubbles will flow a longer distance along with the separation liquid, so that the contact time between the bubbles and the separation liquid will increase, thereby improving the mass transfer efficiency between the bubbles and the separation liquid, and improving the utilization rate of the separation liquid and the effect of adsorbing particles;

[0034] (3) To solve the problem that when there is a cavity in the tank, the dust will escape from the device along with the gas, reducing the utilization rate of the separation liquid and the effect of adsorbing particles, the present invention is provided with a pump body component. The rotation of the impeller will drive the connecting plate and several bearings to rotate together. The movement of the bearings will squeeze the hose, so that the separation liquid inside the hose will flow towards the inside of the injection cavity. When the injection cavity is filled with the separation liquid, as the bearings continue to move, the separation liquid inside the injection cavity will be sprayed out of the injection cavity through the injection port. Since the aperture of the injection port is small and dense, the separation liquid sprayed out therefrom will form a mist curtain, so that the dust not mixed with the separation liquid will be mixed through the mist curtain. The mixture after mixing has a larger mass, so that the gas cannot drive it to escape through the gas output pipeline, thereby reducing the amount of dust escaping through the gas output pipeline, increasing the amount of dust mixed with the separation liquid, and improving the utilization rate of the separation liquid;

[0035] (4) In order to solve the problem that the separation liquid inside the inner tank changes in the height of the liquid level due to the increase in gas pressure or other factors, resulting in the isolation component being unable to contact the separation liquid. At this time, several floating cylinders arranged on the outer wall of the fixed plate will change accordingly with the change of the liquid level, so that the hose can contact the separation liquid in time, reducing the probability that the separation liquid inside the injection cavity cannot be replenished due to the change in the position of the separation liquid level, thereby reducing the probability of dust escaping from the gas output pipeline and improving the utilization rate of the separation liquid and the effect of the separation liquid adsorbing particles.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0051] Embodiment 1. Please refer to Figures 1-7 , the present invention is a powder dust removal device for epoxy processing, including a separation liquid input pipe 13. The outer wall of the separation liquid input pipe 13 is fixedly connected with a tank body shell 14, and the outer wall of the tank body shell 14 is fixedly connected with a separation liquid output pipe 15. It further includes:

[0052] An input mechanism 1, which is fixedly connected to the inner wall of the tank body shell 14 and is used to limit the size and input position of the bubbles input into the tank body;

[0053] An isolation mechanism 2, which is fixedly connected to the outer wall of the tank body shell 14 and is used to reduce the escape of particulate gas in the cavity;

[0054] A floating mechanism 3, which is fixedly connected to the inner wall of the isolation mechanism 2 and is used to change the position of the device according to the liquid level position;

[0055] The inner wall of the tank body shell 14 is fixedly connected with an inner tank body 111. A plurality of restriction holes 112 are opened at the bottom of the inner tank body 111, and a slide rail 113 is fixedly connected to the outer wall of the bottom of the inner tank body 111.

[0056] When the dust-containing gas increases due to factors such as gas flow rate, the generated bubbles will gradually approach the separation liquid input pipe 13. Since the diameter of the separation liquid input pipe 13 is larger than the diameter of the inner tank body 111, the flow rate of the separation liquid at the separation liquid input pipe 13 is larger than the flow rate of the separation liquid inside the inner tank body 111. Since the generated bubbles enter the separation liquid from below, when the generated bubbles are closer to the separation liquid input pipe 13, the bubbles will increase with the distance of the separation liquid flow, so that the contact time between the bubbles and the separation liquid will increase, thereby improving the mass transfer efficiency between the bubbles and the separation liquid, and improving the utilization rate of the separation liquid and the effect of adsorbing particles;

[0057] The input mechanism 1 includes:

[0058] The fixing component 11, the outer wall of the fixing component 11 is fixedly connected to the inner wall of the tank body shell 14;

[0059] The sliding component 12, the outer wall of the sliding component 12 is fixedly connected to the outer wall of the fixing component 11.

[0060] The isolation mechanism 2 includes:

[0061] The driving component 21, the outer wall of the driving component 21 is fixedly connected to the inner wall of the tank body shell 14;

[0062] The pump body component 22, the outer wall of the pump body component 22 is slidably connected to the inner wall of the driving component 21.

[0063] The floating mechanism 3 includes:

[0064] The isolation component 31, the outer wall of the isolation component 31 is fixedly connected to the inner wall of the driving component 21;

[0065] The floating component 32, the outer wall of the floating component 32 is fixedly connected to the outer wall of the isolation component 31.

[0066] The fixing component 11 includes a slider 114 slidably connected to the outer wall of the slide rail 113. The outer wall of the slider 114 is fixedly connected with a sliding cavity 115, and a plurality of output holes 116 are opened on the inner wall of the sliding cavity 115.

[0067] The sliding component 12 includes a partition 121 fixedly connected to the inner wall of the bottom of the tank body shell 14. A plurality of reset springs 122 are fixedly connected to the outer wall of the sliding cavity 115. Two gas input cavities 123 are opened on the inner walls of both sides of the inner tank body 111, and two gas input pipes 124 are fixedly connected to the inner walls of the two gas input cavities 123.

[0068] During use, first input the separation liquid from the separation liquid input pipe 13 and let it reach the inside of the tank body shell 14. When there is separation liquid inside the inner tank body 111, introduce the dusty gas into the gas input cavity 123 from the gas input pipe 124. At this time, as the introduced dusty gas gradually increases, the space between the partition plate 121 and the sliding cavity 115 will be filled with the dusty gas. At this time, the output hole 116 is blocked by the outer wall of the inner tank body 111, so that the dusty gas cannot escape. As a result, the dusty gas pushes the sliding cavity 115 to move towards the separation liquid input pipe 13. As the sliding cavity 115 gradually moves, when the output hole 116 reaches the limiting hole 112 along with the movement of the sliding cavity 115, the dusty gas will enter the inside of the inner tank body 111 through the limiting hole 112. Since the inside of the inner tank body 111 is filled with separation liquid at this time, the dusty gas passing through the limiting hole 112 will enter the separation liquid in the form of bubbles;

[0069] Due to factors such as different flow rates of the input dusty gas, the pressure exerted by the dusty gas on the sliding cavity 115 is different. When the flow rate of the dusty gas increases, the bubble density passing through the limiting hole 112 will increase, which may cause bubble aggregation, reduce the contact area between the bubbles and the separation liquid, and lower the mass transfer efficiency. At this time, since the aperture of the limiting hole 112 gradually decreases and the density gradually increases from the sliding cavity 115 to the separation liquid input pipe 13, when the flow rate of the dusty gas increases, the sliding cavity 115 will gradually move towards the separation liquid input pipe 13, so that the output hole 116 will communicate with the gradually decreasing limiting hole 112. The sliding cavity 115 without the output hole 116 will block the larger limiting hole 112 far from the separation liquid input pipe 13, so that the dusty gas passing through the output hole 116 can only enter the inside of the inner tank body 111 through the smaller and denser limiting hole 112, thereby reducing the volume of the bubbles generated by the dusty gas entering the separation liquid inside the inner tank body 111, improving the mass transfer efficiency between the dusty gas and the separation liquid, and the utilization rate of the separation liquid;

[0070] Example two, please refer to Figures 3-11 , the present invention is a powder dust removal device for epoxy processing. On the basis of Example one, the driving component 21 includes a gas output pipeline 211 fixedly connected to the inner wall of the tank body shell 14. A plurality of connecting rods 212 are fixedly connected to the inner wall of the gas output pipeline 211. One end of the plurality of connecting rods 212 far from the inner wall of the gas output pipeline 211 is rotatably connected to a rotating shaft 213. An impeller 214 is fixedly connected to the outer wall of the rotating shaft 213.

[0071] After the device has been running for some time, due to the gradual increase in the pressure of the dust-containing gas, a cavity will be formed in the upper space inside the inner tank body 111. At this time, the bubbles reaching the liquid surface in the separation liquid will burst, causing the dust particles that have not been mixed with the separation liquid inside the bubbles to enter the cavity. At this time, the gas that has come into contact with the separation liquid will escape from the gas output pipe 211, and the escape of the gas will drive the impeller 214 to rotate. The rotation of the impeller 214 will drive the connecting plate 222 to rotate together. At this time, several bearings 223 provided on the outer wall of the connecting plate 222 will rotate around the rotating shaft 213 under the drive of the connecting plate 222;

[0072] The pump body assembly 22 includes two sliding grooves 221 opened on the outer wall of the rotating shaft 213. A connecting plate 222 is slidably connected to the inner walls of the two sliding grooves 221, and several bearings 223 are rotatably connected to the outer wall of the connecting plate 222.

[0073] The isolation assembly 31 includes several guide rods 311 fixedly connected to the inner wall of the gas output pipe 211. A fixing plate 312 is slidably connected to the outer walls of the several guide rods 311. A corrugated pipe 313 is fixedly connected to the outer wall of the fixing plate 312, and a flexible pipe 314 is fixedly connected to the inner wall of the fixing plate 312.

[0074] The floating assembly 32 includes a spraying cavity 321 fixedly connected to the inner wall of the corrugated pipe 313. Several spraying ports 322 are opened on the outer wall of the spraying cavity 321, and several floating cylinders 323 are fixedly connected to the outer wall of the fixing plate 312;

[0075] The inner wall of the spraying port 322 is rotatably connected to the outer wall of the rotating shaft 213.

[0076] The movement of the bearing 223 will squeeze the flexible pipe 314, causing the separation liquid inside the flexible pipe 314 to flow towards the inside of the spraying cavity 321. When the separation liquid fills the inside of the spraying cavity 321, as the bearing 223 continues to move, the separation liquid inside the spraying cavity 321 will be sprayed out of the spraying cavity 321 through the spraying ports 322. Since the apertures of the spraying ports 322 are small and dense, the separation liquid sprayed out therefrom will form a mist curtain, mixing the dust that has not been mixed with the separation liquid through the mist curtain. The mixture after mixing has a large mass, so that the gas cannot drive it to escape through the gas output pipe 211, reducing the amount of dust escaping through the gas output pipe 211, increasing the amount of dust mixed with the separation liquid, and improving the utilization rate of the separation liquid;

[0077] When the separation liquid inside the inner tank body 111 changes in the height of the liquid level due to the increase in gas pressure or other factors, resulting in the isolation component 31 being unable to contact the separation liquid. At this time, several floating cylinders 323 arranged on the outer wall of the fixing plate 312 will change accordingly with the change of the liquid level, so that the hose 314 can contact the separation liquid in time, reducing the probability that the separation liquid inside the injection cavity 321 cannot be replenished due to the change in the position of the separation liquid level, thereby reducing the probability of dust escaping from the gas output pipe 211 and improving the utilization rate of the separation liquid and the effect of the separation liquid adsorbing particles.

[0078] A specific application of this embodiment is as follows: During use, first input the separation liquid from the separation liquid input pipe 13 and reach the inside of the tank body shell 14. When there is separation liquid inside the inner tank body 111, introduce the dust-containing gas into the gas input cavity 123 from the gas input pipe 124. At this time, as the introduced dust-containing gas gradually increases, the space between the partition plate 121 and the sliding cavity 115 will be filled with the dust-containing gas. At this time, the output hole 116 is blocked by the outer wall of the inner tank body 111, so that the dust-containing gas cannot escape, and thus the dust-containing gas pushes the sliding cavity 115 to move towards the separation liquid input pipe 13. As the sliding cavity 115 gradually moves, when the output hole 116 reaches the limiting hole 112 as the sliding cavity 115 moves, the dust-containing gas will enter the inside of the inner tank body 111 through the limiting hole 112. Since the inside of the inner tank body 111 is filled with separation liquid at this time, the dust-containing gas passing through the limiting hole 112 will enter the separation liquid in the form of bubbles.

[0079] Due to factors such as the different flow rates of the input dust-containing gas, the pressure exerted on the sliding cavity 115 by the dust-containing gas is different. When the flow rate of the dust-containing gas increases, the bubble density passing through the limiting hole 112 will increase, which may cause bubble aggregation, reducing the contact area between the bubbles and the separation liquid and lowering the mass transfer efficiency. At this time, since the aperture of the limiting hole 112 gradually decreases and the density gradually increases from the sliding cavity 115 to the separation liquid input pipe 13, when the flow rate of the dust-containing gas increases, the sliding cavity 115 will gradually move towards the separation liquid input pipe 13, so that the output hole 116 will communicate with the gradually decreasing limiting hole 112, and the sliding cavity 115 without the output hole 116 will block the larger limiting hole 112 far from the separation liquid input pipe 13, so that the dust-containing gas passing through the output hole 116 can only enter the inside of the inner tank body 111 through the smaller and denser limiting hole 112, thereby reducing the volume of the bubbles generated by the dust-containing gas entering the separation liquid inside the inner tank body 111 and improving the mass transfer efficiency between the dust-containing gas and the separation liquid and the utilization rate of the separation liquid.

[0080] When the dust-containing gas increases due to factors such as gas flow rate, the generated bubbles gradually approach the separation liquid input pipe 13. Since the diameter of the separation liquid input pipe 13 is larger than the diameter of the inner tank body 111, the flow rate of the separation liquid at the separation liquid input pipe 13 is larger than the flow rate of the separation liquid inside the inner tank body 111. Since the generated bubbles enter the separation liquid from below, when the generated bubbles are closer to the separation liquid input pipe 13, the bubbles will increase with the distance of the separation liquid flow, so that the contact time between the bubbles and the separation liquid will increase, thereby improving the mass transfer efficiency between the bubbles and the separation liquid, and improving the utilization rate of the separation liquid and the effect of adsorbing particles;

[0081] After the device operates for a period of time, due to the gradual increase in the pressure of the dust-containing gas, a cavity will be generated in the upper space inside the inner tank body 111. At this time, the bubbles reaching the liquid surface in the separation liquid will burst, so that the dust particles not mixed with the separation liquid in the bubbles will enter the cavity. At this time, the gas that has contacted the separation liquid will escape from the gas output pipe 211. The escape of the gas will drive the impeller 214 to rotate. The rotation of the impeller 214 will drive the connecting plate 222 to rotate together. At this time, several bearings 223 arranged on the outer wall of the connecting plate 222 will rotate around the rotating shaft 213 driven by the connecting plate 222. The movement of the bearing 223 will squeeze the hose 314, so that the separation liquid inside the hose 314 will flow into the inside of the injection cavity 321. When the injection cavity 321 is filled with the separation liquid, as the bearing 223 continues to move, the separation liquid inside the injection cavity 321 will be sprayed out of the injection cavity 321 through the injection port 322. Since the aperture of the injection port 322 is small and dense, the separation liquid sprayed out therefrom will form a mist curtain, so that the dust not mixed with the separation liquid will be mixed through the mist curtain. The mixture after mixing has a large mass, so that the gas cannot drive it to escape through the gas output pipe 211, thereby reducing the escape amount of dust through the gas output pipe 211, increasing the mixing amount of dust and separation liquid, and improving the utilization rate of the separation liquid;

[0082] When the separation liquid inside the inner tank body 111 changes in the height position of the liquid level due to the increase in gas pressure or other factors, resulting in the isolation component 31 being unable to contact the separation liquid. At this time, several floating cylinders 323 arranged on the outer wall of the fixing plate 312 will change accordingly with the change of the liquid level, so that the hose 314 can contact the separation liquid in time, reducing the probability that the separation liquid inside the injection cavity 321 cannot be replenished due to the change in the position of the separation liquid level, and further reducing the probability of dust escaping from the gas output pipe 211, and improving the utilization rate of the separation liquid and the effect of the separation liquid adsorbing particles.
