Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flue gas treatment, specifically to an environmental protection type zinc calcine flue gas treatment device. BACKGROUND

[0002] Zinc calcine is the product obtained after roasting of zinc concentrate, mainly containing zinc oxide, zinc sulfate and zinc sulfide, etc., and is mainly used for zinc smelting. It is the main raw material for zinc smelting, and the market demand is mainly for zinc smelting plants as raw materials for smelting zinc. Gas is generated during the production of zinc calcine, and there are many harmful substances in the gas, so the flue gas generated during the production of zinc calcine often needs to be treated.

[0003] After searching, it is found that in the prior art, the authorized patent with publication number CN212855040U discloses a flue gas treatment equipment for producing zinc calcine, which comprises a smoke hood, an air inlet pipe, an air extractor and a filtering device. The filtering device is composed of a filter screen, an activated carbon screen and a box body. A cleaning mechanism that can rotate and stretch for cleaning is arranged between the filter screen and the activated carbon screen. The flue gas treatment equipment for producing zinc calcine realizes twice evolution of the flue gas. The first evolution removes the particulate impurities in the flue gas, and the second evolution extracts harmful substances from the flue gas. Three groups of spiral vanes rotate to drive the rotating brushes at both ends to rotate and clean the wall surface of the filter screen and the activated carbon screen. By arranging springs, the rotating rod swings back and forth on the fixed rod under the elastic force of the two springs, thereby achieving the impact effect on the filter screen and the activated carbon screen, and the cleaned particles and dirt on the filter screen and the activated carbon screen are impacted into the integrated box for collection.

[0004] However, the above technical solution still has the following disadvantages when in use: in the above device, after the flue gas passes through the filter screen, the filtered impurities will gather on the side of the filter screen away from the rotating brush, so that the rotating brush cannot clean the dust-filtered side of the filter screen, and the rotating brush can only clean the fixed area of the filter screen, so the cleaning effect is very limited. To solve the above problems, we propose an environmental protection type zinc calcine flue gas treatment device. UTILITY MODEL CONTENTS
