Abstract

The invention discloses a waste incineration fume treatment system which comprises a water washing device, a liquefying device and a filtering device, wherein the water washing device is connected with the liquefying device through a pipeline A; the liquefying device is connected with the filtering device through a pipeline B; the water washing device comprises a main air inlet tube, a settling tank, a washing tank and a spraying part; the liquefying device comprises an air pipeline, a driving device, a water turbine and a water storage tank; the filtering device comprises a shell, an activated carbon layer and an air outlet; the main air inlet tube, the pipeline A, the air pipeline and the pipeline B are connected in sequence. Due to the water washing device, the liquefying device and the filtering device, thick fume generated from incineration can be subjected to procedures of water washing purification, high-pressure atomization and filtration discharge in sequence, the structure is simple, the process design is reasonable, and the problem of fume pollution caused by waste incineration can be effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of waste incineration flue gas purification and treatment, and relates to a waste incineration flue gas treatment system. Background technique [0002] With the development of the economy, the amount of domestic waste is also increasing. At present, there are three main methods of domestic waste disposal: sanitary landfill, high-temperature composting and incineration for energy production. Since the two methods of sanitary landfill and high-temperature composting will cause serious environmental pollution problems, incineration to produce energy is the direction of municipal solid waste treatment. However, the flue gas produced by the incineration of domestic waste after high-temperature incineration contains a large amount of harmful components such as dioxins, heavy metals, and HCl, so the flue gas must be treated before being discharged up to the standard. With the vigorous promotion of national energy...
