Description

Technical Field

[0001] This invention relates to the field of exhaust gas purifier technology, and specifically to an exhaust gas purifier with multi-layer filtration function. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. When these waste gases are emitted during industrial production, they often have harmful effects on the environment and human health. Therefore, purification measures need to be taken before they are released into the atmosphere to ensure that they meet the requirements of waste gas emission standards. Common types of waste gas purification include flue gas purification from thermal power plants, dust gas purification from workshops, organic waste gas purification, odor purification, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] Existing exhaust gas purifiers consist of a body, a liquid pump, spray pipes, an air inlet, an air outlet, and a liquid outlet. During operation, the liquid pump is activated to draw solution from a solution tank. This solution is then sprayed onto the exhaust gas entering through the air inlet via the spray pipes. The exhaust gas settles upon contact with the sprayed liquid, precipitating inside the body along with the waste liquid. The filtered exhaust gas is then discharged through the air outlet. However, because exhaust gas treatment relies on spraying to filter the gas through direct contact, some exhaust gas rises directly to the top of the unit without contacting the spray, resulting in low treatment efficiency. Therefore, we propose an exhaust gas purifier with multi-layer filtration capabilities. Summary of the Invention

[0051] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] This invention provides a waste gas purifier with multi-layer filtration function, comprising: a purifier body 1, an air pump 503, a spray structure, a drying and filtration structure 4, and a sealing structure 901; wherein the interior of the purifier body 1 is adapted to purify waste gas; the purifier body 1 includes a first liquid storage chamber 5 and a second liquid storage chamber 501 arranged from bottom to top; the first liquid storage chamber 5 is connected to an air inlet pipe 101; the air inlet pipe 101 is adapted to deliver waste gas toward the first liquid storage chamber 5; the second liquid storage chamber 501 is connected to an air outlet pipe 102; the air pump 503 is disposed on one side of the purifier body 1; one side of the air pump 503 is connected to the first liquid storage chamber 5, and the other side is connected to the second liquid storage chamber 501; the air pump 503 is adapted to drive the gas in the first liquid storage chamber 5 into the second liquid storage chamber 501; the spray structure is disposed on... On one side of the purifier body 1, a portion of the spray structure is adapted to extend into the second liquid storage chamber 501 and spray liquid into the second liquid storage chamber 501; a drying 4 filter structure is disposed within the second liquid storage chamber 501; the drying 4 filter structure is located above the portion of the spray structure extending into the second liquid storage chamber 501; the drying 4 filter structure is adapted for gas to pass through and for filtering moisture in the gas; a sealing structure 901 is disposed within the second liquid storage chamber 501, the sealing structure 901 having a sealing state and a connected state; when the sealing structure 901 is in the sealing state, the liquid in the second liquid storage chamber 501 cannot enter the first liquid chamber; when the sealing structure 901 is in the connected state, the liquid in the second liquid storage chamber 501 is adapted to enter the first liquid storage chamber 5 through the sealing structure 901.

[0053] In this scheme, the exhaust gas first enters the first liquid storage chamber 5 and is filtered for the first time. Then, through the air pump 503, the exhaust gas enters the second liquid storage chamber 501 for a second filtration. In the second liquid storage chamber 501, under the action of the spray structure, it undergoes a third filtration. Through three filtrations, the exhaust gas is filtered, maximizing the efficiency of exhaust gas treatment. Subsequently, the exhaust gas passes through the drying filter structure 4 to dry it before being discharged. By changing the state of the sealing structure 901, the liquid in the second liquid storage chamber 501 can flow into the first liquid storage chamber 5, realizing the secondary utilization of the liquid in the second liquid storage chamber 501 and reducing costs.

[0054] Furthermore, the spray structure includes: a solution tank 2, a liquid pump 3, and a spray pipe 301; wherein the solution tank 2 is located on one side of the purifier body 1; the liquid pump 3 is located on the top of the solution tank 2, and the liquid pump 3 is adapted to drive the liquid in the solution tank 2 into the second liquid storage chamber 501; one end of the spray pipe 301 is connected to the liquid pump 3, and the other end is adapted to penetrate the purifier body 1 and communicate with the second liquid storage chamber 501.

[0055] Furthermore, the spray structure also includes an atomizing nozzle 302, which is connected to the spray pipe 301; the solution in the spray pipe 301 is atomized and pressurized by the atomizing nozzle 302 and then sprayed out.

[0056] Furthermore, it also includes a stirring structure, which is disposed inside the body 1 of the purifier; the stirring structure is adapted to stir the liquid in the first liquid storage chamber 5 and the second liquid storage chamber 501.

[0057] Specifically, the stirring structure also includes a stirring rod 6, a connecting rod 603, and a scraper 604, wherein the connecting rod 603 is disposed inside the purifier body 1; the stirring rod 6 is rotatably connected to the purifier body 1 via a bearing seat; one end of the connecting rod 603 is connected to the stirring rod 6; the scraper 604 is connected to the other end of the connecting rod 603; the scraper 604 is adapted to scrape and clean the inner walls of the first liquid storage chamber 5 and the second liquid storage chamber 501.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The purifier body 1 is connected to a solution tank 2 and a control box 104 on one side. The purifier body 1 is provided with a first liquid storage chamber 5 and a second liquid storage chamber 501. A drying filter structure 4 is installed on the upper side of the second liquid storage chamber 501. An air inlet pipe 101 and a drain pipe 103 are connected to the bottom of the purifier body 1. An air outlet pipe 102 is connected to the upper side of the purifier body 1. A replenishment pipe 201 is installed on one side of the solution tank 2. A liquid pump 3 is installed on the top of the solution tank 2. One side of the liquid pump 3 is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to the solution tank 2. A spray pipe 301 is connected to the top of the liquid pump 3. One end of the spray pipe 301 passes through the purifier body 1 and is inserted into the second liquid storage chamber 501. An air pump 503 is installed on one side of the purifier body 1.

[0059] Furthermore, the stirring structure also includes a hydraulic cylinder 702, which is adapted to be connected to the stirring rod 6; the hydraulic cylinder 702 is adapted to drive the stirring rod 6 to rotate.

[0060] In specific implementation, in order to prevent some unfiltered exhaust gas from directly escaping to the top of the purifier body 1, when purifying exhaust gas, the exhaust gas is first introduced into the first liquid storage chamber 5 inside the purifier body 1 through the air inlet pipe 101, so that the exhaust gas is mixed with the solution inside the first liquid storage chamber 5 for preliminary filtration. Then, the air pump 503 and the liquid pump 3 are started to introduce the gas that has been preliminarily filtered in the first liquid storage chamber 5 into the second liquid storage chamber 501 through the air extraction pipe 503a and the air delivery pipe 503b, where it is mixed with the solution in the second liquid storage chamber 501 for secondary filtration.

[0061] Furthermore, a threaded connection layer 902 is provided on the outer surface of the stirring rod 6; the stirring rod 6 is threadedly connected to the sealing structure 901 through the threaded connection layer 902.

[0062] Furthermore, a drain pipe 103 is provided, which is connected to the bottom of the first liquid storage chamber 5; the drain pipe 103 is adapted to drain the liquid in the first liquid storage chamber 5.

[0063] Furthermore, a control box 104 is also provided, which is located on one side of the purifier body 1.

[0064] Furthermore, a filter screen 504 is also provided, which is disposed inside the air intake pipe 101; the filter screen 504 prevents sediment from entering the pipe body.

[0065] The outer side of the air pump 503 is connected to the body 1 of the purifier through the air extraction pipe 503a and the air delivery pipe 503b respectively. The ends of the air extraction pipe 503a and the air delivery pipe 503b away from the air pump 503 are respectively inserted into the first liquid storage chamber 5 and the second liquid storage chamber 501. A filter screen 504 is installed at one end of the air inlet pipe 101, the air extraction pipe 503a and the air delivery pipe 503b. One end of the air inlet pipe 101 is connected to the bottom of the first liquid storage chamber 5.

[0066] After secondary filtration, the gas continues to dissipate upwards towards the upper part of the purifier body 1. At this time, the liquid pump 3 pumps the solution in the solution tank 2 to the spray pipe 301 through the connecting pipe. The solution in the spray pipe 301 is atomized and pressurized by the atomizing nozzle 302 and sprayed out to perform a third filtration on the upward dissipating gas. After the gas has completed three filtrations, it comes into contact with the drying filter structure 4 to remove the water vapor carried in the gas and then is discharged from the outlet pipe 102. This exhaust gas purifier with multi-layer filtration function can effectively improve the purification efficiency of exhaust gas by having the exhaust gas undergo two soaking and mixing filtrations and one spray filtration, and then being discharged after drying.

[0067] See Figure 1 , Figure 2 , Figure 5 and Figure 6It is known that a stirring rod 6 is rotatably mounted inside the purifier body 1 via a bearing seat. A first mounting block 601 and a second mounting block 602 are respectively mounted on the outside of the stirring rod 6. The outside of the first mounting block 601 and the second mounting block 602 are both connected to one end of a connecting rod 603. The other end of the connecting rod 603 is connected to a scraper 604 on the adjacent side. A drive gear 7 is inserted through the top of the purifier body 1 on the upper side of the stirring rod 6. The outside of the drive gear 7 meshes with a drive rack 701. One side of the drive rack 701 is connected to one end of an extension rack 903. The other end of the extension rack 903 is connected to one end of a hydraulic cylinder 702. The outside of the hydraulic cylinder 702 is inserted into a sliding sleeve 703, and the bottom of the sliding sleeve 703 is welded to the purifier body 1.

[0068] In practice, to accelerate the mixing rate of gas and solution, hydraulic cylinder 702 is activated. Hydraulic cylinder 702 drives drive rack 701 to move back and forth repeatedly. During this repetitive motion, drive rack 701 meshes with drive gear 7 mounted on top of stirring rod 6, causing drive gear 7 and stirring rod 6 to rotate. This, in turn, causes the first mounting block 601 and second mounting block 602, along with their outer connecting rod 603 and scraper 604, to rotate, driving the solution to flow and ensuring sufficient contact with the gas while facilitating the discharge of gas from within the solution. During rotation, scraper 604... During the process, the inner walls of the first liquid storage chamber 5 and the second liquid storage chamber 501 are scraped and cleaned to prevent the sediment of waste gas and solution from adhering to the inner walls, which facilitates the subsequent cleaning of the purifier body 1. The ends of the air inlet pipe 101, the air extraction pipe 503a, and the air delivery pipe 503b are all equipped with filter screens 504 to effectively prevent sediment from entering the pipe body and to filter the gas passing through the pipe body to prevent the pipe body from clogging. This waste gas purifier with multi-layer filtration function is equipped with a stirring rod 6, a connecting rod 603, and a scraper 604 to ensure that the gas and solution are fully mixed.

[0069] See Figure 1 , Figure 2 and Figure 7 It is known that the outer side of the hydraulic cylinder 702 is connected to one end of the electric push rod 704, the outer side of the electric push rod 704 is connected to the sliding sleeve 703, the drive rack 701 and the extension rack 903 are both provided with guide grooves 8, and guide rods 801 are inserted through the guide grooves 8. The two ends of the guide rods 801 are respectively connected to the purifier body 1 and the sliding sleeve 703. The purifier body 1 is equipped with a threaded connecting pipe 9, which is threadedly connected to the sealing structure 901. The outer side of the stirring rod 6 is provided with a threaded connecting layer 902, and the stirring rod 6 is threadedly connected to the sealing structure 901 through the threaded connecting layer 902.

[0070] In specific implementation, in order to improve the utilization rate of the solution and make full use of the effective substances inside the solution, after the solution in the second storage chamber 501 has been used for a period of time, the electric push rod 704 is activated to retract. When the electric push rod 704 retracts, it will drive the hydraulic cylinder 702 to move along the sliding sleeve 703, which will drive the extended rack 903 connected to the hydraulic cylinder 702 to mesh with the drive gear 7. At this time, the drive gear 7 drives the stirring rod 6 to rotate. The stirring rod 6 drives the sealing structure 901 to move upward along the threaded connecting pipe 9 through the threaded connection layer 902 until the channel inside the sealing structure 901 moves into the second storage chamber 501.

[0071] At this time, the solution inside the second liquid storage chamber 501 will flow into the first liquid storage chamber 5 through the channel inside the sealing structure 901 for storage and to complete the first filtration of the exhaust gas. After the second liquid storage chamber 501 releases part of the solution, the electric push rod 704 extends again to drive the sealing structure 901 to reset and stop the flow of solution. At this time, the solution in the second liquid storage chamber 501 is the solution that has been drawn from the solution tank 2 by the liquid pump 3 and sprayed through the spray pipe 301 and the atomizing nozzle 302 to undergo the third filtration with the gas. The solution in the first liquid storage chamber 5 is the solution after the second filtration is completed in the second liquid storage chamber 501. The guide groove 8 and the guide rod 801 are set to facilitate the stable movement of the drive rack 701 and the extension rack 903. This exhaust gas purifier with multi-layer filtration function can realize multi-stage utilization of solution, so that the effective substances in the solution can be fully utilized and the solution utilization rate can be improved.

[0072] In summary, when using this exhaust gas purifier with multi-layer filtration function, exhaust gas is introduced into the first liquid storage chamber 5 through the air inlet pipe 101. The air pump 503 and the liquid pump 3 are started through the control box 104 to introduce the gas that has been preliminarily filtered in the first liquid storage chamber 5 into the second liquid storage chamber 501 for secondary filtration. The liquid pump 3 pumps the solution in the solution tank 2 into the spray pipe 301 through the connecting pipe. The solution in the spray pipe 301 is atomized and pressurized by the atomizing nozzle 302 and sprayed out to perform a third filtration on the upward-dispersing gas. The gas after three filtrations comes into contact with the drying filter structure 4 and is dried by the drying filter structure 4 before being discharged from the exhaust pipe 102. The replenishment pipe 201 is used to replenish the solution in the solution tank 2, and the drain pipe 103 is used to discharge the solution inside the purifier body 1.

[0073] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
