Garbage air drying treatment system and method

Abstract

The invention discloses a garbage air drying treatment system. The garbage air drying treatment system comprises a low-temperature air drying production device and a connected garbage air drying treatment device. The garbage air drying treatment device includes a first garbage air drying cylinder provided with a first spiral turning plate on the inner wall; the first spiral turning plate is overturned under rotation of the first garbage air drying cylinder to push garbage to move; an intake port of the first garbage air drying cylinder is connected with the low-temperature air drying production device; low-temperature dry air is blown out in the axial direction of the first garbage air drying cylinder; and the operation direction of the low-temperature dry air is the same with the pushing direction of the garbage. The garbage air drying treatment device further includes a second garbage air drying cylinder; and the operation direction of the low-temperature dry air in the second garbage air drying cylinder is opposite to the pushing direction of the garbage. The invention further discloses a treatment method of the garbage air drying treatment system. The garbage air drying treatment system uses high-temperature tail gas as a hot air source and natural wind and fed wind to produce the low-temperature dry air; and the low-temperature dry air performs dehydration and air drying for garbage raw materials, so that the storage and the transportation are facilitated, the garbage pyrolysis efficiency is improved, and the effects of environmental protection and feasibility are achieved.

Description

technical field [0001] The invention relates to the technical field of garbage pretreatment, in particular to a garbage air-drying treatment system and method. Background technique [0002] The per capita annual output of municipal solid waste in my country has reached about 500 kilograms, and it is increasing at a rate of 8% to 10% every year. The substantial increase in the total amount of garbage is mainly due to the increase in city size, number of cities and urban population. Municipal solid waste treatment facilities are important municipal infrastructure in cities and an important part of urban public environmental sanitation systems, which are related to the degree of civilization of a city and the vital interests of the broad masses of the people. Although the investment in domestic waste treatment facilities in my country has increased year by year, the efficiency of domestic waste harmless treatment is still very low. The lack of waste harmless treatment technolo...
