Device and method for carrying out adsorption purification treatment on sticky or moisture-containing dust smoke

Abstract

The invention relates to a device and a method for carrying out adsorption purification treatment on sticky or moisture-containing dust smoke. The device comprises an adsorbent storage unit, a smoke purification unit, a pipeline unit, an adsorbent conveying unit, an air pressure balance unit, a fan unit, a chimney and a control unit, wherein the bottom of the adsorbent storage unit is connected with the adsorbent conveying unit, a feeding hole of the adsorbent conveying unit is connected with the pipeline unit at an entrance of the smoke purification unit, and an exit of the smoke purificationunit, the fan unit and the chimney are connected by virtue of the pipeline unit; the air pressure balance unit is arranged at the top of the adsorbent storage unit, and the other end of the air pressure balance unit is connected with the pipeline unit at the entrance of the smoke purification unit; and the control unit controls the whole adsorption purification technological process. Compared with the prior art, the invention has the beneficial effects that the device and the method have good purification effect on sticky or moisture-containing dust smoke and have the characteristics of low investment cost, simple structure, high purification efficiency and long service life.

Description

Technical field [0001] The invention relates to the field of flue gas dust removal, in particular to a device and method for adsorbing and purifying flue gas with viscous or wet dust. Background technique [0002] The flue gas discharged from the coke oven production process contains tar and other viscous substances. If the tar substance in this kind of flue gas enters the bag filter without treatment, it will inevitably cause a paste bag, which will damage the filter bag and affect the normal operation of the dust collector. . In the previous technology, the combustion + water washing method is mostly used for treatment, but this treatment method has disadvantages such as high energy consumption, large water consumption, and secondary pollution, especially for the implementation of the existing coke oven flue gas purification. Difficult; in addition, the flue gas during the commissioning stage of the equipment in the waste incineration industry tends to have relatively high moi...

AI Technical Summary

Problems solved by technology

[0002] The flue gas discharged from the coke oven production process contains tar and other viscous substances. If the tar substances in the flue gas are not treated and directly enter the bag filter, it will inevitably cause sticky bags, which will damage the filter bag and affect the normal operation of the dust collector.

In the previous technology, the combustion + water washing method was often used for treatment, but this treatment method has disadvantages such as high energy consumption, large water consumption, and secondary pollution, especially for the implementation of the existing coke oven coal charging flue gas purification. Difficult; in addition, the flue gas during the commissioning stage of equipment in the waste incineration industry often has relatively high moisture content and low flue temperature. If the wet flue gas is not treated and directly enters the bag filter, it will also cause sticky bags and bag damage. Thus affecting the normal operation of the equipment

In the previous technology, debugging cloth bags were often used to replace them, and the working filter bags were replaced after the equipment was put into production. However, this method has the disadvantages of waste of resources, high cost, and increased workload of replacing filter bags.
