Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and specifically relates to a filter that can change the temperature of a gas. Background Technology

[0002] In industrial production, filters are the core equipment for gas purification. They remove impurities such as dust and particulate matter from gases through physical interception and adsorption, ensuring the stable operation of subsequent equipment and production safety. In processes such as chemical synthesis, petroleum cracking, and steel smelting, the temperature of the gas directly affects the reaction efficiency and product quality. For example, in chemical catalytic reactions, the raw material gas needs to be preheated to a specific temperature to enhance the reaction activity, while the protective gas for precision instruments needs to be cooled to room temperature to prevent the equipment from overheating. Therefore, in actual production, precise control of gas temperature is just as important as filtration and purification.

[0003] Existing gas filters generally only have a single filtration function and lack temperature regulation capabilities. When exposed to high-temperature gases, such as high-temperature exhaust gases from chemical reactions or hot gases from metallurgical furnaces, they can easily lead to catalyst deactivation, aging and deformation of precision instrument components, and even equipment failure if they are directly introduced into subsequent equipment without being cooled. When handling low-temperature gases, such as the low-temperature gas flow in natural gas liquefaction processes or the cold source gases in food freezing processes, condensation and ice formation are likely to occur. This can not only block the internal channels of the filter but also freeze and crack pipes, causing equipment damage and seriously affecting production safety and efficiency. Utility Model Content

[0009] In the above technical solution, further, the lower end of the moving block is uniformly connected with cleaning plates, and the number of cleaning plates is six sets, with multiple cleaning plates respectively contacting both sides of multiple inner water pipes.

[0010] In the above technical solution, furthermore, a cleaning brush is connected to one side of each of the multiple cleaning plates corresponding to one side of the inner water pipe, and the cleaning brush is in contact with one side of the inner water pipe.

[0011] In the above technical solution, a ash outlet is further provided at the lower middle part of the second connecting frame, and guide blocks are connected to both sides of the lower end of the inner wall of the second connecting frame corresponding to the upper end of the ash outlet.

[0025] like Figures 1-7 The image shows a filter that can change the temperature of a gas.

[0026] Example 1

[0027] The system includes a first connecting frame 1, with a second connecting frame 3 connected to one side of the first connecting frame 1. A square flange 2 is connected to one end of the first connecting frame 1 and one end of the second connecting frame 3, and the two square flanges 2 are connected by fixing bolts. A filter plate 4 is embedded in the inner wall of the first connecting frame 1. A water conveying assembly is connected to the middle of one side of the second connecting frame 3, and a dust removal mechanism is connected to the middle of the upper end of the second connecting frame 3. The water conveying assembly includes a water tank 5, with water pipes 6 connected to both the upper and lower parts of one side of the water tank 5. The upper water pipe 6 is the inlet pipe, and the lower water pipe 6 is the outlet pipe. Water valves are connected to the outer walls of both water pipes 6. A water pump 7 is connected to the lower end of the inner wall of the water tank 5, and a conveying valve is connected to the output end of the water pump 7. Pipe 8, one end of the conveying pipe 8 passes through the water tank 5 and the second connecting frame 3 and extends into the interior of the second connecting frame 3. One end of the conveying pipe 8 is connected to a fixed pipe 9. One side of the fixed pipe 9 is connected to one side of the inner wall of the second connecting frame 3 through a first mounting block. One end of the fixed pipe 9 is evenly connected to an inner water pipe 10. There are three sets of inner water pipes 10. The inner water pipes 10 are arranged in an S-shaped structure. One end of each inner water pipe 10 is connected to an installation pipe 11. One end of the installation pipe 11 is connected to a drain pipe 12. One end of the drain pipe 12 passes through the second connecting frame 3 and the water tank 5 in sequence and extends into the interior of the water tank 5. One side of the drain pipe 12 is connected to one side of the inner wall of the second connecting frame 3 through a second mounting block.

[0028] A sealing groove is added to the connection surface of the two square flanges 2, with an embedded annular sealing ring to improve the airtightness of the connection. An elastic sealing gasket is added between the filter plate 4 and the inner wall of the first connecting frame 1 to prevent gas bypass leakage. A temperature control device is connected inside the water tank 5. A temperature sensor and a liquid level sensor are added inside the water tank 5 to realize real-time monitoring of water temperature and water level.

[0029] Example 2

[0030] The dust removal mechanism includes a housing 13. A motor 14 is connected to the middle of one side of the housing 13. A lead screw 15 is connected to the output end of the motor 14. One end of the lead screw 15 extends through the housing 13 and is connected to one side of the inner wall of the housing 13. A moving block 16 is slidably connected to the outer wall of the lead screw 15. Stabilizing rods are connected to both sides of the lead screw 15 on one side of the inner wall of the housing 13. The moving block 16 slides on the outer wall of the two stabilizing rods. A through hole is opened on the moving block 16 at the location of the stabilizing rod. The two stabilizing rods are located inside the two through holes respectively. Cleaning plates 17 are evenly connected to the lower end of the moving block 16. There are six sets of cleaning plates 17. Multiple cleaning plates 17 contact both sides of multiple inner water pipes 10 respectively. A cleaning brush is connected to one side of each cleaning plate 17 corresponding to one side of the inner water pipe 10. The cleaning brush contacts one side of the inner water pipe 10.

[0031] The upper end of the second connecting frame 3 has an opening corresponding to the lower part of the housing 13, which facilitates the insertion of the cleaning plate 17 into the second connecting frame 3. The cleaning brush adopts a detachable design, and the bristles are made of high temperature resistant and wear-resistant synthetic fibers to improve its service life and extend its life. The housing 13 and the second connecting frame 3 are connected by mounting bolts. The dust removal mechanism is detachable, which facilitates the maintenance and replacement of the cleaning plate 17.

[0032] Example 3

[0033] The lower middle part of the second connecting frame 3 has a ash outlet. The lower end of the inner wall of the second connecting frame 3 is connected to both sides of the upper end of the ash outlet, and the upper end of the guide block 18 is inclined. The lower end of the second connecting frame 3 is connected to a collection box 19. The lower middle part of the inner wall of the collection box 19 is slidably connected to a cleaning box 20. One end of the cleaning box 20 extends through to one side of the collection box 19. A pull plate is connected to one side of the cleaning box 20. Electric telescopic rods 21 are rotatably connected to the lower part of both sides of the inner wall of the collection box 19. Baffles 22 are evenly rotatably connected to both sides of the inner wall of the collection box 19. The upper ends of two electric telescopic rods 21 are rotatably connected to one side of the lower end of one baffle 22, and the upper ends of the other two electric telescopic rods 21 are rotatably connected to one side of the lower end of the other baffle 22.

[0034] Dust can be discharged downwards through the dust inlet. Two guide blocks 18 prevent the dust from drifting out or entering the first connecting frame 1. The dust can be easily collected through the cleaning box 20. When the electric telescopic rod 21 retracts, it pulls the two baffles 22. The two baffles 22 are set in a V-shape to guide the dust into the cleaning box 20. The cleaning box 20 can be pulled out by pulling the pull plate for easy processing of the dust.

[0035] Working principle: When using the device, the gas to be treated enters from one side of the first connecting frame 1, passes through the filter plate 4 embedded in the inner wall, filters out impurities such as dust and particulate matter, and the filtered clean gas enters the second connecting frame 3 for temperature adjustment.

[0036] In heating mode, open the water supply valve of the water supply pipe 6 above the water tank 5 to inject hot water, and at the same time close the water supply valve of the water supply pipe 6 below. Start the water pump 7, and the hot water enters the water pump 7 and is pumped into the fixed pipe 9 through the delivery pipe 8. It is then distributed to three sets of S-shaped inner water pipes 10. When the hot water flows in the inner water pipes 10, it exchanges heat with the external gas through the pipe wall, releasing heat to heat the gas. The cold water after heat exchange flows back to the water tank 5 through the installation pipe 11 and the drain pipe 12. After being heated by the internal heating equipment, it re-enters the circulation.

[0037] In cooling mode, open the water supply valve of the water supply pipe 6 above the water tank 5 to inject cold water, and at the same time close the water supply valve of the water supply pipe 6 below. The cold water is transported to the inside of the water tank 5 through the water supply pipe 6. The water pump 7 works and pumps the water into the fixed pipe 9 through the delivery pipe 8, and then distributes it to the three sets of S-shaped inner water pipes 10. When the hot water flows in the inner water pipes 10, the inner water pipes 10 absorb the heat of the gas and become warm water. The warm water flows back to the water tank 5 through the drain pipe 12. After being cooled by the internal cooling device, it re-enters the circulation, realizing continuous cooling of the gas.

[0038] Normally, the electric telescopic rod 21 is in the extended state, pushing the baffle plate 22 to flip upwards and tightly fit against both sides of the ash outlet, forming a seal to prevent gas leakage into the collection box 19. When the ash cleaning mechanism is working, the motor 14 drives the lead screw 15 to rotate, causing the moving block 16 sleeved on the lead screw 15 to reciprocate linearly along the stabilizer rod. The six sets of cleaning plates 17 at the lower end of the moving block 16 move synchronously with it. The cleaning brushes on the cleaning plates 17 are in close contact with the outer wall of the S-shaped inner water pipe 10, scraping the pipe through back-and-forth friction. During the cleaning process, dust and ash on the wall detach and slide down the outer wall of the inner water pipe 10 to the bottom of the second connecting frame 3. After the cleaning plate 17 completes the cleaning of the inner water pipe 10, the electric telescopic rod 21 retracts, causing the baffle plate 22 to flip downwards and open the ash outlet. The guide block 18 at the bottom of the second connecting frame 3 guides the dust to slide down the slope and fall into the cleaning box 20 inside the collection box 19 through the ash outlet. After cleaning is completed, the electric telescopic rod 21 extends again, and the baffle plate 22 resets to close the ash outlet, preventing gas from escaping. The user can pull out the cleaning box 20 through the pull plate to empty the dust.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
