Description

Technical Field

[0002] Petrochemical gas refers to the gas produced in the petrochemical production process. Petrochemical gas can include a variety of gases, such as ethylene, propylene, hydrogen, methane, carbon monoxide, carbon dioxide, nitrogen, etc. These gases are usually used as energy, raw materials or intermediates in the petrochemical production process.

[0003] In the petrochemical production process, solid particles such as dust, impurities, and sediments are often present in the fuel gas. The particles will rub against the inner wall of the equipment in the high-speed airflow, resulting in increased wear of the equipment and shortening the service life of the equipment. The particles will accumulate and clog in narrow parts such as pipes, valves, and nozzles, affecting the flow and transmission of the fuel gas. In order to protect the normal operation of petrochemical equipment and systems, extend the life of the equipment, and improve production efficiency and safety, it is necessary to filter the petrochemical fuel gas for particles to remove the solid particles therein and ensure the purity and quality of the fuel gas. During use, the existing fuel gas particle purifier filters the particles by fixing the particle filter inside the shell. Although it can play a filtering role, the method of replacing the particle filter is relatively cumbersome. The cover plate and the shell of the fuel gas particle purifier are often fixed with multiple bolts. The disassembly and assembly process is relatively cumbersome and not fast enough.

[0026] The working principle of this utility model:

[0027] When it is necessary to purify the gas, the gas pipeline is connected through the shell 101, and the gas will pass through the particle filter 201 and the filter element 204, so that the particle filter 201 and the filter element 204 filter the particle impurities in the gas. When it is necessary to replace the particle filter 201, the disassembly rod 601 is pulled to the left by manpower and the moving block 602 is moved to the left. The moving block 602 will drive the two movable blocks 604 and the two cylinders 605 to move to the left. During the movement of the two cylinders 605, the two inclined blocks 503 will move toward the opposite ends by squeezing. The two inclined blocks 503 will drive the two sliders 502 and the two locking blocks 501 to move out from the inside of the two plug-in blocks 3. At this time, the cover plate 103 can be moved upward and disengaged from the shell 101, and the four control blocks 9 will be disengaged from the four control columns 10, so that the particles can pass through. The filter screen 201 moves upward, and the bolts fixing the connecting block 202 and the filter element 204 are removed, so that the connecting block 202 is separated from the particle filter screen 201, so that the filter element 204 can be replaced. When it is necessary to fix the cover plate 103 to the shell 101, the movement of the moving block 602 will cause the two return springs 603 to deform. After the disassembly rod 601 is loosened, the elastic action of the two return springs 603 causes the moving block 602 to drive the disassembly rod 601, the two movable blocks 604 and the two cylinders 605 to rebound to their original positions. The movement of the two sliders 502 will cause the two tension springs 504 to deform. When the disassembly rod 601 is loosened, the elastic action of the two tension springs 504 causes the two sliders 502 to drive the two locking blocks 501 to rebound to the inside of the two plug-in blocks 3, and the two inclined blocks 503 rebound to their original positions, so that the cover plate 103 and the shell 101 are fixed.
