Problems solved by technology

Although waste incineration and power plants have been established in some cities, due to the small amount of treatment, the treatment process is accompanied by harmful gas (dioxin), sewage (garbage leachate), waste residue (high content of heavy metals) and other discharge problems. The incineration method is still controversial

Abstract

The invention discloses a dry-process cement preheating decomposition system. The dry-process cement preheating decomposition system comprises a decomposition furnace, wherein a decomposition assisting mechanism is arranged on one side of the decomposition furnace; a pulverized coal burner is arranged at the lower end of the decomposition furnace; a dilution cooler is arranged on one side of the pulverized coal burner; a dilution air blower is connected to one side of the dilution cooler; the upper end of the dilution cooler is connected with a cyclone separator; the upper end of the cyclone separator is connected with dechlorination equipment, one side of the dechlorination equipment is connected with a dust collector; one side of the dust collector is connected with an induced draft fan; and a rotary kiln is further arranged on one side of the pulverized coal burner. The system can be used for treating harmful gas (dioxin) in the household garbage incineration process in a dry-process cement preheating decomposition system.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a dry-process cement preheating decomposition system. Background technique [0002] With the improvement of people's living standards, the discharge of domestic waste is also increasing. At present, my country's municipal solid waste stockpile has reached 6 billion tons, occupying 500 million square meters of arable land, producing 200 million tons of municipal solid waste every year, and will grow rapidly at a rate of 9%. These large quantities of domestic waste have constituted an increasingly serious threat to the ecological environment in and around the city. [0003] Traditional garbage disposal methods include landfill, composting, and incineration. Urban garbage disposal in my country started relatively late, and at present it is mainly sanitary landfill. Although waste incineration and power plants have been established in some cities, due to the small amount ...
