Dedusting, purifying and filtering process for waste incineration flue gas

Abstract

The invention relates to a dedusting, purifying and filtering process for waste incineration flue gas, which is mainly completed by matching a dedusting, purifying and filtering device for waste incineration flue gas, and specifically comprises the following steps: S1, mounting the device, S2, filtering flue gas, S3, washing the device, and S4, carrying out recycling. The device can solve the problems that when existing equipment is used for purifying flue gas, the filtering equipment cannot be cleaned and replaced in time, after being used for a long time, smoke dust impurities easily block the filtering equipment and affect the filtering effect of smoke, and when the existing equipment is used for cleaning the filtering equipment, the cleaning effect is poor, cleaning is inconvenient, dust adhering to the outer side of a filtering net is easily extruded into the filtering net, and the service life of the filtering net is affected are solved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal and purification, in particular to a dust removal, purification and filtration process for waste incineration flue gas. Background technique [0002] Garbage incineration is an older and traditional method of garbage disposal. After the garbage is treated by incineration, the reduction effect is remarkable, the land is saved, and various pathogens can be eliminated, and toxic and harmful substances can be converted into harmless substances. The waste incineration method has become one of the main methods of urban waste disposal. However, waste incineration will produce a large amount of harmful gases and impurities, so it is necessary to further purify the incineration flue gas. [0003] At present, the existing garbage incineration flue gas usually has the following defects when it enters and exits the purification and filtration treatment: 1. When the existing equipment purifies th...

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot clean and replace the filtering equipment in time when the flue gas is purified. After a long time of use, the dust and impurities are easy to block the filtering equipment and affect the filtering effect of the flue gas. Moreover, When the existing equipment cleans the filter equipment, the cleaning effect is poor, it is inconvenient to clean, and it is easy to squeeze the dust adhering to the outside of the filter to the inside of the filter, which affects the service life of the filter and other problems
