Description

Technical Field

[0001] This application belongs to the field of coal gas treatment technology, specifically a treatment device for waste gas from coal-fired power generation. Background Technology

[0002] When coal gas is used for power generation or processing, it produces a large amount of waste gas containing a large amount of dust and harmful substances, so it needs to be treated.

[0003] For example, CN219002573U discloses a treatment device for waste gas from coal-fired power generation, including a waste gas treatment box. An inlet pipe is fixedly installed on the front side wall of the waste gas treatment box, and an auxiliary pipe is provided on the inlet pipe. A drain pipe is fixedly installed at the bottom of the left side wall of the waste gas treatment box, and an injection pipe is fixedly installed at the top of the left side wall of the waste gas treatment box. A spray device is provided at the top of the inner side of the waste gas treatment box. The injection pipe passes through the corresponding wall surface of the waste gas treatment box and is connected to the input end of the spray device inside the waste gas treatment box. A drain pump is provided at the bottom of the inner side of the waste gas treatment box. In this utility model, the waste gas treatment device for coal-fired power generation can effectively replace the activated carbon filter plate through a detachable mounting plate, which greatly improves the filtration effect of the device on impurities in the waste gas.

[0004] However, in this application, the mounting plate and the exhaust pipe are connected by a mounting groove, which makes the sealing effect of the structure poor and inconvenient to replace, resulting in some gas being incompletely filtered and emitted into the air. Utility Model Content

[0011] By adopting the above technical solution, the water injection pipe allows external water to be transported into the interior of the exhaust gas treatment box for spraying, which filters and reduces dust in the exhaust gas. At the same time, the water outlet pipe facilitates the discharge of used water from the interior of the exhaust gas treatment box.

[0012] In a preferred embodiment, an inlet pipe is provided on one side surface of the exhaust gas treatment box, and an auxiliary pipe is provided on the surface of the inlet pipe.

[0013] By adopting the above technical solution, the inlet pipe and auxiliary pipe are designed to facilitate the entry of exhaust gas into the interior of the exhaust gas treatment box.

[0014] In a preferred embodiment, the mounting plate has an upper filter plate and a lower filter plate inside it, which are fixed by a bracket.

[0015] By adopting the above technical solution, the fixed frame facilitates the installation of the upper and lower filter plates inside the mounting plate, and the structure can also filter the emitted gas.

[0016] In a preferred embodiment, a movable sleeve is provided between the upper filter plate and the lower filter plate, and a plurality of activated carbons are provided on the surface of the movable sleeve by means of a limiting plate.

[0017] By adopting the above technical solution, the setting of the limiting plate facilitates the placement of activated carbon, and in conjunction with other structures such as the movable sleeve, further filtration can be performed.

[0018] In a preferred embodiment, the inside of the inlet pipe and the auxiliary pipe is provided with a barrier filter plate and an inner plate, and a guide block and an air guide groove are provided between the barrier filter plate and the inner plate.

[0019] By adopting the above technical solution, through the guide block, air guide groove and barrier filter plate set inside the inlet pipe, the waste gas injected into the waste gas treatment box can be effectively blocked, and the waste gas purification effect inside the waste gas treatment box can be effectively improved.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, by setting the threaded structure and the sealing ring structure, the exhaust pipe and the mounting plate can be sealed and installed, effectively preventing the internal exhaust gas from overflowing. At the same time, the threaded connection of stud one, stud two and internal thread can facilitate the installation and replacement of this structure, while the setting of sealing ring one and sealing ring two can play a sealing role.
