Description

Technical Field

[0001] The utility model relates to the field of purification structures for treating dusty waste gas, and more specifically, to a purification structure for treating dusty waste gas. Background Art

[0002] In the environmental protection industry, a bag filter is the main equipment for treating waste gas generated during the incineration of various boilers and incinerators. The main body structure of the dust collector is roughly divided into a hopper, an air inlet pipe, a middle box, an upper box, an air outlet pipe, a bypass air pipe, a blowpipe, a filtering device, etc. The specific principle is described as follows: Under the negative pressure of the fan, the flue gas enters the dust collector housing through the main air inlet pipe and the short air inlet pipe. The coarse dust falls into the hopper, and the fine dust rises with the air flow into the middle box. The middle box is filled with filter cloth. The air flow passes through the filter cloth and retains the fine dust in the flue gas on the outer surface of the filter cloth. The filtered clean air enters the upper box and then reaches the air outlet pipe, and the dust removal process ends. When a certain amount of fine dust adheres to the outer surface of the filter cloth, the blowpipe blows the filter cloth by releasing high-pressure air flow, and blows the fine dust on the outer surface of the filter cloth into the hopper.

[0003] However, the conventional bag dust removal is to directly blow the filter cloth by releasing high-pressure air flow. This method has insufficient dust removal strength and poor dust removal effect, and cannot completely remove the dust on the filter cloth. In the long run, it may block the filter cloth and reduce the service life of the machine.

[0004] In the prior art, the authorized announcement number CN212383354 of the utility model discloses a device for treating purified dusty waste gas, which relates to the technical field of waste gas treatment. The utility model includes a housing, and a wind guide cover is fixedly communicated with the top surface of the housing; a dust discharge hopper is fixedly communicated with the bottom surface of the housing; a blowpipe is fixedly communicated with the top surface of the wind guide cover; a dust discharge pipe is fixedly communicated with the top end of the dust discharge hopper; a clean air discharge pipe is fixedly communicated with one side surface of the wind guide cover; a miscellaneous air inlet pipe is fixedly communicated with one side surface of the housing; and a dust purification mechanism is fixedly installed inside the housing at a position corresponding to the space between the wind guide cover and the dust discharge hopper. The dust purification mechanism includes an upper cover plate and a lower bottom plate.

[0005] In the above patent, through the design of the first dust cleaning component, the second dust cleaning component and the third dust cleaning component, during the self-cleaning process of the dust removal bag, the surface of the dust removal bag can be reciprocally patted by swinging left and right, and through the auxiliary patting, the self-cleaning rate and self-cleaning effect of the dust removal bag can be enhanced. In the above patent, a patting mechanism is adopted, and when patting, the dust raising property is large, and the patting range is limited, and its outer surface cannot be comprehensive. In the actual equipment, a cage mechanism needs to be arranged outside the dust removal bag, and the patting range is smaller and the cleaning efficiency is low. Summary of the Utility Model
