Household garbage comprehensive disposal and multicomponent utilization method

Abstract

The invention discloses a household garbage comprehensive disposal and multicomponent utilization method, which belongs to the technical field of resources and environmental protection. Municipal household garbage is presorted into two parts including organic combustibles and inorganic muck; after presorting, the organic combustibles are conveyed to a garbage power plant so as to be burnt to generate power, generated slag enters a dry cement production line and is used as cement raw materials so as to be mixed, generated fly ash enters the dry cement production line, and the inorganic muck isconveyed to the dry cement production line so as to be burnt in a cement kiln and then is used as cement raw materials so as to be mixed. According to the household garbage comprehensive disposal andmulticomponent utilization method, the problem of small scale of cooperative garbage disposal of an existing cement kiln is solved, and the problem of slag and fly ash disposal in garbage power is solved; a good environmental effect is guaranteed, the high household garbage disposal capability is provided, recycling is realized during household garbage disposal, and a good economic effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of resource and environment protection. Background technique [0002] With the development of society and the continuous enhancement of people's awareness of environmental protection, the disposal of domestic waste has become a hot spot in the field of environmental protection. Waste incineration has become the main development direction of domestic waste disposal in my country in the future. At present, the co-processing of domestic waste and waste-to-energy in cement kilns has become increasingly common. It has matured and become the main way of waste incineration disposal, and has developed rapidly. However, there are still obvious deficiencies in practice. The co-processing of cement kilns has achieved good environmental protection effects, but the disposal scale is relatively low. A 5000t / d new dry-process cement production line generally co-processes domestic waste of about 500t / d. There is a big gap w...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to: propose a comprehensive domestic waste disposal and multi-component utilization method, which not only solves the problem of small scale of waste co-processing in existing cement kilns, but also solves the problem of processing slag and fly ash in waste power generation; It has a good environmental protection effect and has a large domestic waste treatment capacity. It can realize recycling while disposing of domestic waste, and has good economic effects.
