Embodiment Construction

[0017] Such as figure 1 The shown industrial waste cracking and incineration tail gas treatment system includes tail gas cooling tower 1, multi-layer filter tower 2, multi-layer bag filter 3, bio-affinity dust removal tower 4, tail gas recirculation system 5, induced draft fan 6, air Compressor 7, dust collection tower 8, blower 9. The tail gas produced in the cracking waste incinerator is connected to the gas inlet of the tail gas cooling tower 1 through the pipeline, and the tail gas from the incinerator first enters the tail gas cooling tower 1, and the temperature of the tail gas is reduced to 50°C-80°C to meet the requirements of the subsequent bag dust removal . The cooling water in the tail gas cooling tower 1 is atomized by compressed air and then sprayed into the tail gas cooling tower 1 to directly contact the tail gas. The height of the tail gas cooling tower is set high enough to ensure that the sprayed atomized water can evaporate completely. While cooling down,...

Abstract

The invention discloses an industrial garbage cracking and incineration tail gas dust removal treatment system, which comprises a tail gas cooling tower, a multi-layer filter tower, a multi-layer bag filter, a bio-affinity dust removal tower, a tail gas recirculation system, an induced draft fan, and an air compressor , dust collection tower, blower, etc. In the multi-layer filter tower, grapefruit peel packing is used as square block packing, and the packing volumes in each packing box from bottom to top are 8cm3, 3.375cm3, and 1cm3 respectively. This treatment system is particularly effective for the removal of micro-sized particles. After the treatment system, the removal rate of particles with a particle size of less than 2.5 μm in the exhaust gas reaches more than 99.5%, and the removal rate of particles with a particle size of less than 0.5 μm reaches 99.0%. above.

Description

technical field [0001] The invention relates to an industrial waste cracking and incineration tail gas dedusting treatment system, which belongs to the waste gas treatment field in the field of environmental protection. Background technique [0002] Industrial waste incineration technology has attracted attention for its ability to reduce, recycle, and harmlessly treat waste, and can greatly reduce the landfill area of ​​waste. At present, 68 waste incineration plants have been built nationwide (except Hong Kong, Macao, and Taiwan), with a processing capacity of 33,000 tons per day. The incineration rate has increased from 2.9% in 2013 to the current 12.9%. Due to the particularity of industrial waste, a large amount of gaseous pollutants will inevitably be produced during the incineration process, among which dust is a major air pollutant. If it is not effectively treated, it will cause serious pollution to the environment and endanger human health. In particular, inhalabl...
