[0002] The petrochemical industry is an important part of my country's social development process. The petrochemical industry will produce a large amount of waste gas in the production process. The waste gas contains sulfide, particulate dust and other harmful gases, so these waste gases need to be treated in a timely manner.

[0003] A Chinese patent discloses a highly efficient treatment device for petrochemical waste gas (authorization announcement number: CN218392953U), which pressurizes water through a booster pump and transports it to the nozzle through a water pipe for spraying in the first tower body and the second tower body, and then rotates the motor, which drives the threaded rod to rotate. The rotation of the threaded rod drives the internal thread block to move up and down along the guide rod, so that the nozzle can spray evenly in the first tower body and the second tower body. However, it can be clearly seen from the drawings in the specification that there is a certain gap between adjacent nozzles in the above-mentioned treatment device, that is, when the nozzle starts to spray, a small amount of exhaust gas can easily pass through the gap between the adjacent nozzles, and the particles passing through the exhaust gas cannot be treated for dust reduction, and the purification effect is not ideal.

Through the multiple relatively distributed first nozzles 431 and multiple second nozzles 441 of the spraying mechanism 4, the water columns sprayed out from the first nozzles 431 and the second nozzles 441 can continuously expand outward and form a water curtain after contact, so as to effectively block the particles in the waste gas. Compared with the traditional method, this method can form a tight water curtain inside the first tower body 2, improving the purification effect of the particulate matter in the waste gas.

[0022] A filtering mechanism 5 is installed inside the second tower body 3. A water tank 6 is fixedly connected to one side of the base 1. The filtering mechanism 5 includes a support rod 51, a handle 52 and a first filter screen 53.

The center point of the second dredging rod 58 and the center point of the first filter hole 57 are on the same vertical line. The diameter of the second dredging rod 58 is smaller than the diameter of the first filter hole 57. The number of the second dredging rods 58 is equal to that of the first filter holes 57. The filtering mechanism 5 can improve the filtering effect on the waste gas through the double-layer filtering method. And by pulling up the handle 52, not only can the first dredging rod 56 be driven to move into the second filter hole 59, but also the second dredging rod 58 can be driven to move into the first filter hole 57, so as to timely clean the impurities attached in the first filter hole 57 and the second filter hole 59 and prevent blockage. This method can complete the cleaning work without disassembling the first filter screen 53 and the second filter screen 54, which is more convenient and fast.

[0023] Working principle: When using this device, first loosen the bolt 49, then hold the first collar 47 and the second collar 48 and move them relative to or in the opposite direction of each other, so as to change the distance between the first nozzle 431 and the second nozzle 441. By adjusting the distance between the first nozzle 431 and the second nozzle 441, the tightness of the water curtain can be changed. Then tighten the bolt 49. Next, buckle the second annular plate 31 onto the first annular plate 21 and tighten it with screws. At this time, the second tower body 3 can be fixed on the top of the first tower body 2. Then inject the waste gas from the air inlet 32. Since a spring 55 is installed between the first filter screen 53 and the second filter screen 54, there is a certain distance between the two. At this time, the waste gas is filtered when passing through the first filter screen 53 and the second filter screen 54. The filtered waste gas then enters the first tower body 2. When the first filter screen 53 and the second filter screen 54 are blocked, hold the handle 52 and pull it up and down. Under the elastic force of the spring 55, the first filter screen 53 can be driven to move up and down. At this time, the first dredging rod 56 can be inserted into the second filter hole 59, and the second dredging rod 58 can be inserted into the first filter hole 57, so as to timely clean the impurities attached in the first filter hole 57 and the second filter hole 59 and prevent blockage. This method can complete the cleaning work without disassembling the first filter screen 53 and the second filter screen 54, which is more convenient and fast. Then turn on the first water pump 41 and the second water pump 42. After the first water pump 41 works, the water in the water tank 6 can be injected into the first hollow tube 43 and the first nozzle 431 through the first hose 411, and after the second water pump 42 works, the water in the water tank 6 can be injected into the second hollow tube 44 and the second nozzle 441 through the second hose 421. Since the center points of the first nozzle 431 and the second nozzle 441 are on the same vertical line, the water columns sprayed from the first nozzle 431 and the water columns sprayed from the second nozzle 441 collide after contact, and the generated water droplets continuously extend outward to form a water curtain. The waste gas can perform dust reduction treatment on the internal particles when passing through the water curtain. Finally, the waste water is discharged through the sewage outlet on the rear surface of the first tower body 2, and the waste gas is discharged through the air outlet 22.
