System and method for air-drying treatment of garbage

Abstract

Disclosed are a garbage air-drying treatment system and a treatment method for the garbage air-drying treatment system, wherein the treatment system comprises a low-temperature dry air preparation device (100) and a garbage air-drying treatment device (200) connected thereto; the garbage air-drying treatment device (200) comprises a first garbage air-drying cylinder (30), with an inner wall thereof being provided with a first spiral upending plate (40), wherein the first spiral upending plate (40) turns over, along with the rotation of the first garbage air-drying cylinder (30), and propels garbage to move, an air inlet (32) of the first garbage air-drying cylinder (30) is connected to the low-temperature dry air preparation device (100), low-temperature dry air is blown off in an axial direction of the first garbage air-drying cylinder (30), and a moving direction of the low-temperature dry air is the same as a propelling direction of the garbage; and the garbage air-drying treatment device (200) further comprises a second garbage air-drying cylinder (31), wherein the moving direction of the low-temperature dry air in the second garbage air-drying cylinder (31) is opposite the propelling direction of the garbage therein. The treatment method uses high-temperature exhaust gas as a hot air source and uses natural air as air supplement to prepare the low-temperature dry air, and the low-temperature dry air dehydrates and dries the garbage, thus not only facilitating storage and transportation but also improving the pyrolysis efficiency of the garbage.

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...
