Environment-friendly direct incinerating and gasifying energy supply system of municipal solid wastes and working method thereof

Abstract

The invention discloses an environment-friendly direct incinerating and gasifying energy supply system of municipal solid wastes. The system comprises an incinerating and gasifying energy supplying system and a waste gas treating system, wherein the incinerating and gasifying energy supplying system comprises a special transport vehicle, an ozone deodorizing and sterilizing area, a garbage crusher, a cut-off machine, a low-temperature incinerator and a high-temperature oxygen blowing incinerator; an ozone deodorizing and sterilizing device, a conveying belt and the garbage crusher are arranged in the ozone deodorizing and sterilizing area; the ozone deodorizing and sterilizing device is connected with the garbage crusher; the garbage crusher is connected with the cut-off machine; the cut-off machine is connected with the low-temperature incinerator; the low-temperature incinerator is connected with the high-temperature oxygen blowing incinerator; the waste gas treating system comprises a first wind suction hood, a bag dust collector and an induced draft fan; a plurality of waste gas treating towers are arranged between the bag dust collector and the induced draft fan; and an air outlet of the induced draft fan is connected with a venting chimney. The system disclosed by the invention has the advantages that the potential pollution of hazardous substances such as heavy metal and dioxins in incineration ash and slag can be effectively controlled; harmlessness and recycling are realized; and harmful and noxious substances in waste gas can be comprehensively removed.

Description

technical field [0001] The invention relates to waste recycling equipment, in particular to an environment-friendly urban solid waste direct incineration gasification energy supply system and a working method. Background technique [0002] Municipal solid waste mainly comes from the general waste of urban residents' life and consumption, commercial activities, municipal construction and maintenance, urban landscaping, medical entertainment, etc., as well as residues collected from human and animal feces, kitchen waste, and municipal sludge waste treatment. solid matter such as dust. [0003] With the improvement of environmental protection awareness, people strongly demand that the treatment of municipal solid waste achieve the goals of reduction, harmlessness and resource utilization, and truly realize "garbage from waste to resource". [0004] The thermal treatment technology of municipal solid waste, especially the incineration technology, has been widely popularized and...

AI Technical Summary

Problems solved by technology

[0004] The thermal treatment technology of municipal solid waste, especially the incineration technology, has been widely popularized and applied due to its good volume reduction performance and a certain degree of harmlessness; however, the dioxin-like organic pollutants produced during the incineration process The ash and other secondary pollutants will cause harm and damage to the environmental system near the municipal solid waste incineration plant, which makes people have a new understanding of the shortcomings of the existing incineration technology, and requires the development of more thorough incineration that is harmless and resourceful. new equipment and technologies;

[0005] Moreover, municipal solid waste may produce toxic and harmful gases during the processing process. Therefore, a special waste gas treatment system is required to treat the waste before it can be discharged into the atmosphere. However, most of the current common waste gas treatment systems can only remove Dust and some harmful substances in the exhaust gas; the demand for comprehensive removal of harmful substances cannot be met
