Production system and production method for producing renewable coal by municipal solid waste and coal slime

Abstract

The invention discloses a production system and a production method for producing renewable coal by municipal solid waste and coal slime. The production system comprises a feeding bin, a magnetic separator, a primary crusher, a primary high-speed rotating machine, a secondary crusher, a secondary high-speed rotating machine, an environment-friendly air heating furnace, a municipal solid waste bin, an additive bin, a coal slime bin and a molding machine. The production method comprises the steps of: roughly sorting by manpower, magnetically separating, primarily crushing, primarily dewatering, secondarily crushing, secondarily dewatering, baking, mixing, extruding and molding to prepare the product finally. According to the invention, the municipal solid waste is subjected to harmless treatment, and comprehensively utilized together with a by-product-coal slime in coalmine production, so as to become a new energy source, so that the pollution on the environment can be reduced, and the waste is changed into wealth. The coal slime in the coalmine production is mixed with the municipal solid waste, so that the product is easy to burn, not easily crushed, and wide in application range. Therefore, the product produced by the invention can be applied to various fields of production and life, and can completely form a large scale and industrialization.

Description

technical field [0001] The invention belongs to the technical field of resource treatment methods of urban domestic garbage, and in particular relates to a production system and production method for producing recycled coal by utilizing urban domestic garbage and coal slime. Background technique [0002] At present, there are several treatment methods for municipal solid waste in China: 1. Incineration power generation: This technology is mainly used for domestic waste treatment in large and medium-sized cities. Because the project has a large demand for waste, it is not suitable for development in small and medium-sized cities, because power plants occupy The land area is large, requiring certain land resources, and because the garbage is easy to pollute the environment during the collection, storage and production, it is easy to cause social conflicts; 2. Landfill treatment: At present, this technology is the main method of garbage treatment in small and medium-sized citie...

Problems solved by technology

Due to these characteristics, it is difficult to stack, store and transport coal slime, especially when it is stacked, its shape is extremely unstable, it will be lost when it meets water, and it will fly when it is air-dried. As a result, it not only wastes valuable resources, but also causes serious damage. Environmental pollution, sometimes even restricting the normal production of coal washing plants, has become a more difficult problem in coal preparation plants. At present, only a small part of them are made into coal bricks for civilian use, while most of them have not been developed and utilized.
