Description

Technical Field

[0001] The utility model belongs to the field of dust purification treatment, and specifically relates to a wet and efficient dust purification treatment device. Background Technique

[0002] The common equipment for coke oven flue gas dust removal is a pulse bag filter. The bag filter uses cloth bags to filter the dust-containing gas. The dust is adsorbed on the outer side of the cloth bags, and the dust is removed by back blowing through the back blowing dust cleaning system, and the dust falls into the ash hopper.

[0003] The patent application with the publication number of CN211987817U discloses a purification treatment device for coke oven flue gas dust and tar, including: a polymer powder adding mechanism, a dust removal mechanism, a dust cleaning mechanism and a draft fan. The flue gas inlet of the dust removal mechanism is connected with a flue gas inlet pipe, the flue gas outlet of the dust removal mechanism is connected with the air inlet pipe of the draft fan, and the draft fan is used to extract the coke oven flue gas entering the dust removal mechanism. The air outlet of the dust cleaning mechanism is arranged on the inner wall of the top of the dust removal mechanism, and the conveying pipeline of the polymer powder adding mechanism is communicated with the flue gas inlet pipe before the flue gas inlet of the dust removal mechanism. The utility model separates and purifies the coke oven flue gas by adopting a PTFE film bag filter and combining the polymer powder coating process. The addition amount of the polymer powder can be adjusted according to the content ratio of tar, moisture and other contents in the coke oven flue gas, so as to achieve the purpose of efficient filtration and purification of the coke oven flue gas, effectively protect the dust collector and improve the work.

[0004] However, the above technology has the following disadvantages when used:

[0005] As described in paragraph 0029 of the above document, "By blowing a certain amount of polymer powder into the flue gas inlet pipe as a filtration auxiliary medium, the extremely fine dust and tar in the coke oven flue gas in the flue gas inlet pipe are captured and coated by the polymer powder to form powder balls. The heavy powder balls fall into the ash hopper of the dust removal mechanism by their own weight and the action of the settling air flow. After the limestone powder coats the fine dust and tar, it falls into the ash hopper. The coke oven flue gas treated by the polymer powder reduces the moisture content and hydrophilicity, making the coke oven flue gas entering the dust removal mechanism dry and not humid, avoiding the phenomenon of filter material caking in the dust removal mechanism and improving the service life of the filter material." And from the attached Figure 1 It can be seen that the inner side wall of the ash hopper 2 is inclined, and the fine dust and tar generated by the dust removal mechanism 1 will fall into the interior of the ash hopper 2 for collection. Because the tar contains moisture inside, it will cause the tar to accumulate on the inner side wall of the ash hopper 2. As the tar accumulates on the inner side wall of the ash hopper 2, more and more fine dust will accumulate on the inner side wall of the ash hopper 2, and it is very easy to cause the problem of fine dust clogging on the inner side wall of the ash hopper 2.

[0006] Therefore, a wet and efficient dust purification treatment device is proposed to solve the above disadvantages. Content of the Utility Model
