Description

Technical Field

[0001] The present application relates to the technical field of dust removal devices, and more specifically, to a boiler flue gas dust removal device. Background Art

[0002] When the boiler treats industrial waste gas by combustion, a large amount of dust particles will be accompanied by the flue gas generated, and the temperature of the waste gas generated by the combustion is relatively high. If it is directly discharged without dust removal and cooling treatment, it will cause air pollution and greenhouse effect, seriously affecting the surrounding living environment. The existing boiler flue gas dust removal device with the public technology number CN214552207U proposes a screen to block the smoke that may exist in the floating gas, and at the same time, the flushing pipe can flush the screen. The water flow flushed by the flushing pipe and the secondary spray pipe is accumulated in the mud trough II, and is drained from the mud outlet pipe II to the sedimentation tank to realize the dust removal treatment of the boiler flue gas. However, when used, the dust removal device in the reference is installed horizontally when treating the boiler flue gas, and it is difficult to clean the dust of the screen with the cleaning pipe. It is easy to accumulate on the upper surface of the screen, and the dust will be discharged together with the cleaning liquid, which increases the sewage purification equipment and difficulty, and the high-temperature flue gas cannot realize waste heat recovery, resulting in energy waste. In view of this, we propose a boiler flue gas dust removal device. Utility Model Content
