Small-scale municipal sludge and household waste synergetic incineration treatment method

Abstract

The invention relates to a small-scale municipal sludge and household waste synergetic incineration treatment method. The small-scale municipal sludge and household waste synergetic incineration treatment method comprises a municipal sludge incineration system, a household waste synergetic treatment system, a waste heat recycling device and a smoke purifying system. The municipal sludge incineration system comprises a sludge feeding device, a sludge drying machine and a sludge incineration device which are sequentially connected in series. The household waste synergetic treatment system comprises a waste feeding device and a waste pyrolysis gasification furnace which are connected in series. The gas outlet end of the waste pyrolysis gasification furnace communicates to the sludge incineration device, and generated pyrolysis gasification gas is introduced into an assistant combustion device through a draught fan. The waste heat recycling device is a waste heat boiler, the waste heat boiler is used for generating steam by heating boiler feed water, the steam communicates with a turbine generator set, the turbine generator set utilizes the steam generated by the waste heat boiler through absorbing heat to generate electricity, the electricity is used for auxiliary power supply supplementation of the municipal sludge incineration system and the household waste treatment system. First-grade exhausted steam of the turbine generator set is conveyed into the sludge drying machine to be used as a heat source for drying the sludge. The smoke generated after sludge incineration is processed by the smoke purifying system and is discharged after reaching standards.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment and disposal, in particular to a small-scale municipal sludge and domestic waste co-incineration treatment method. Background technique [0002] With the gradual attention of the relevant national departments to the treatment and disposal of solid waste, the relevant environmental protection standards have been gradually improved. After the large-scale implementation of domestic waste treatment and disposal projects, the treatment of municipal sludge has become a very urgent problem. [0003] Municipal sludge is usually produced from municipal sewage treatment plants. Municipal sludge has high organic content, is unstable, is perishable and contains a large number of germs, parasites and heavy metal pollutants. cause serious pollution. Compared with the rapid improvement of the efficiency of domestic waste treatment and sewage treatment, the situation of municipal sludge treatment a...
