Municipal garbage automatic processing system

Abstract

The invention relates to a municipal refuse automatic treatment system which is characterized in that: the hand-sorting garbage is transported to a magnetic separator by a belt conveyor for the magnetic separation; after the iron-containing material is separated, the garbage is sent into a marsh gas generating pool for fermentation. The generated marsh gas is pressured to become liquid and supplied to users for use; the dry matter of a marsh gas tank is discharged from a sewage draining exit and enters into a centrifuge to be removed a majority of moisture content, and is sent into a kiln for dry; after being dried, the dry matter contains 5-10% of moisture content; after the dry matter is crashed by a muller, the dry matte enters into a brick press to be manufactured into bricks. The system has the advantages of little investment; the generated marsh gas is used by users, the iron content matter, aluminum matter and glass vessels which are sorted out are reused. The refuse is manufactured into bricks for building; therefore, the system is beneficial to the municipal environment comprehensive treatment, and can reduce secondary pollution and changes waste into valuable.

Description

technical field [0001] The invention belongs to an urban garbage treatment device, in particular to a garbage treatment system capable of producing biogas. Background technique [0002] Urban waste disposal has become one of the problems to be solved to solve urban environmental pollution and create a green city. At present, there are two main types of urban waste disposal, one is deep burial, the problem of this method is land occupation, and it is easy to pollute groundwater. Another way is the combustion method, which requires a large investment and low waste utilization rate, which will cause a lot of secondary pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide an automatic treatment system for urban garbage. The system has the advantages of less investment, less environmental pollution, large amount of urban garbage treatment, and can generate biogas to provide to users. [0004] The technical solution...
