Abstract

The invention discloses a municipal sludge drying and incineration system. The system comprises an incinerator, wherein a smoke outlet of the incinerator is communicated with a sludge dryer; a tail gas outlet of the sludge dryer is connected with a heat exchanger and the incinerator respectively; the heat exchanger is communicated with a tail gas treatment system; one path of a discharge port of the sludge dryer is communicated with the incinerator, while the other path is communicated with a pyrolyzing furnace; and a discharge port of the pyrolyzing furnace is respectively communicated with an activated carbon tail gas treatment system and the incinerator. The invention also discloses a process for treating the municipal sludge drying and incineration system. The system has the advantages of simple system formation, small energy consumption in sludge treatment process, no secondary pollution, concise whole processing procedure, low failure rate and the like.

Description

[0001] technical field [0002] The invention relates to an environmental protection process, in particular to a municipal sludge drying and incineration system and a treatment process thereof. Background technique [0003] At present, domestic and foreign sludge treatment and disposal methods mainly include landfill, incineration, and land utilization. Sludge landfills occupy a large amount of land, and the leachate and gas produced will seriously pollute groundwater and the atmosphere. When land is used, because the sludge contains pathogenic bacteria, parasite eggs, heavy metals and various refractory organic compounds, it will endanger human health and the growth of animals and plants. Incineration is the most thorough means to realize the harmlessness, reduction and stabilization of sludge, and its proportion in sludge treatment and disposal is increasing year by year. It has become the main technology adopted by developed countries, but its technology and equipment in...
