Treatment process of ash generated after environmental waste power generation

Abstract

The invention discloses a treatment process of ash generated after environmental waste power generation. Devices used in the treatment process comprises an ash chamber, a screening machine, a pulverizer, a melting pool, a metal adsorption recovery pool, a filter screen, an evaporation chamber, a calcining chamber, a natural cooling chamber, a grinding machine, a water tank and a mineral powder chamber. According to the treatment process, the ash generated after combustion is prepared into a cement admixture through the reasonable process and equipment according to the characteristics of overwater garbage in a hydropower station, the cement admixture, in which metal ions are removed, is better in workability, the uniformity of a cement product is improved, and the cracks are reduced; the particles filtered by the filter screen are formed into brick mud which can be directly used for producing construction firebricks; besides, after sintering, the brick mud, in which metal ions are removed, is higher in rigidity and strength, and fine cracks are fewer; stove ash is converted into the cement admixture with the relatively high use value and economic value, and a quite high social value is achieved.

Description

technical field [0001] The invention relates to follow-up treatment equipment for garbage incineration, in particular to a process for treating ash after generating electricity from environmental garbage. Background technique [0002] Hydropower stations rely on hydropower to generate electricity. China has many rivers such as the Yangtze River, the Yellow River, and the Lancang River, which are used for relatively abundant hydropower resources in the world. The construction of hydropower stations has always been the main source of energy. With the expansion of human life, modern More and more traces of life are scattered to various places, and more and more domestic garbage, production and natural garbage flow into ditches and rivers with rainwater, and finally accumulate in front of the dams of hydropower stations, forming quite Spectacular garbage dump. Among the garbage, there are leaves, branches, and even whole trees from the mountains, straw, crops, agricultural waste...
