Incineration smoke gas ultralow exhaust purification treatment method and treatment system thereof

Abstract

The invention discloses an incineration smoke gas ultralow exhaust purification treatment method, including treatment of sludge incineration, garbage incineration, solid waste incineration, hazardouswaste incineration smoke gas exhaust, and treatment of ceramsite kiln and cement kiln cooperated disposal waste exhaust smoke gas, and is also applicable to the treatment of exhaust smoke gas of otherindustrial kiln systems. The treatment device comprises an activated carbon powder spraying / mixing device, a cloth bag dust removing device, a primary alkali liquor spraying device, an ozone spraying / mixing device, a secondary alkali liquor spraying device, a draft fan, a water spraying device, a defogging device, a cooling tower and a chimney in sequential connection. The incineration exhaust smoke gas is connected with the activated carbon powder spraying / mixing device through a pipeline and enters the treatment device system; finally, the purified gas is exhausted through the chimney. Themethod has the beneficial effects that the operation flexibility is high; by aiming at the condition of different concentrations of contaminants in the incineration exhaust smoke gas, the addition ofreagents such as the activated carbon powder, ozone and alkali liquor and the like is regulated, so that the environment-friendly exhaust requirements can be met.

Description

technical field [0001] The present invention relates to incineration flue gas treatment technology, in particular to a treatment system for sludge incineration, garbage incineration, solid waste incineration, hazardous waste incineration exhaust flue gas, and ceramsite kiln and cement kiln co-processing waste exhaust gas treatment system and its Approach. Background technique [0002] With the development of social economy, the amount of industrial solid waste (including sludge, etc.) generated in the production process of enterprises is increasing day by day. Industrial solid waste is a serious pollution to the ecological environment, if not properly disposed of, it will leave great hidden dangers to people's health, environment and economic development. The incineration flue gas generated during the incineration process, the pollutant emission depends on the composition of the incineration waste and the incineration process conditions. It mainly includes incomplete combus...

AI Technical Summary

Problems solved by technology

[0003] With the increasing emphasis on environmental protection, environmental protection departments in various places have become more stringent in controlling the concentration and total amount of pollutant emissions. Traditional flue gas treatment technologies have been difficult to meet environmental protection needs and need to be improved to achieve standard treatment of flue gas.
