Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically to a petrochemical gas filtration and emission device. Background Technology

[0002] With the rapid development of the petrochemical industry, the requirements for petrochemical gas filtration have also increased. For example, Chinese patent CN217473064U discloses a petrochemical gas filtration and emission device, but there are still some problems. For example, when petrochemical gas is washed by the washing liquid, the washing process is completed by simply injecting it into the washing liquid and then discharged. This results in incomplete contact between the petrochemical gas and the washing liquid, and the washing quality required for normal operation cannot be fully achieved. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a petrochemical gas filtration and emission device that enables petrochemical gas to fully contact with the washing liquid, thereby improving the washing quality of petrochemical gas.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A petrochemical gas filtration and emission device includes a base plate, on which the following are disposed:

[0006] The first processing box has an air inlet pipe on one side and a conveying pipe on the other side. An acceleration mechanism and a filtration mechanism are fixedly connected to the inner wall of the first processing box.

[0007] The second processing tank is located on one side of the first processing tank and is connected to the first processing tank through the conveying pipe.

The bottom end of the inlet pipe extends to the bottom of the second processing tank. A spray pipe is fixedly connected to the water outlet end of the water pump. An atomizing spray head is fixedly connected to the spray pipe.

[0008] The condensate exhaust tower is located on one side of the second processing tank and is connected to the second processing tank via an exhaust pipe.

[0009] Furthermore, the acceleration mechanism includes a mounting ring fixedly connected to the inner wall of the first processing tank. A drive motor is fixedly connected to the inner wall of the first processing tank via a support rod. The drive motor is located on one side of the mounting ring, and a rotating rod is fixedly connected to the output end of the drive motor. One end of the rotating rod extends to the inner side of the mounting ring and is fixedly connected to an acceleration fan blade. By setting up the drive motor and the acceleration fan blade, the transmission speed of petrochemical gas is effectively increased.

[0010] Furthermore, the number of accelerating fan blades is no less than five and they are arranged in a ring array.

[0011] Furthermore, the number of stirring plates is no less than five and they are arranged in a circular array.

[0012] Furthermore, the number of atomizing spray heads is no less than nine and they are arranged in a rectangular array.

[0013] Furthermore, the conveying pipe, the drain pipe, and the exhaust pipe are all equipped with pipe valves.

[0014] Furthermore, the filtration mechanism is located on one side of the acceleration mechanism and includes a first filtration structure and a second filtration structure. The filtration mechanism effectively adsorbs and filters petrochemical gases.

[0016] Furthermore, the second filter structure includes a second connecting ring, which is fixedly connected to the inner wall of the first processing box, and a silicone filter screen is fixedly connected to the inner wall of the second connecting ring.

[0017] Technical effects of this utility model:

[0018] Compared with existing technologies, the petrochemical gas filtration and emission device of this utility model, by installing a waterproof motor and a stirring plate in the second treatment tank, can effectively stir the washing liquid in the second treatment tank, so that the petrochemical gas and the washing liquid can be in more complete contact, thereby improving the washing quality and efficiency; by setting a water pump and atomizing spray head, the washing liquid can be effectively sprayed above the washing liquid, thereby performing secondary washing of the petrochemical gas through the atomized washing liquid, making the washing more complete, and achieving the effect of improving the filtration quality of petrochemical gas.
