Domestic garbage and shale cracking furnace

Abstract

The invention discloses a domestic garbage and shale cracking furnace which comprises a furnace body. The furnace body is sequentially provided with a gas reservoir, a cracking layer, a drying layer and a high temperature layer from top to bottom; a gas outlet and a safety valve are arranged on the top part of the furnace body; a feed inlet is formed at a position, located on the gas reservoir, onthe side of the furnace body; a spiral slag hole is formed in the bottom part of the furnace body; a plurality of rotary shafts are arranged on the gas reservoir, the cracking layer and the drying layer, and are driven through a gearbox; a plurality of stirrer are arranged on the bottom part of the high temperature layer and are connected with an external motor; the motor is used for providing power for the stirrer; and an air inlet is further formed in the side of the high temperature layer. According to the domestic garbage and shale cracking furnace provided by the invention, no any auxiliary fuel needs to be added during cracking; during a mixed garbage cracking process, the volume reduction rate reaches to more than 90 percent, and odor and noise cannot cause adverse effects on the environment; and a mixed garbage cracking burning mixture is applied to turbine generation, power transmission and grid-connection.

Description

technical field [0001] The invention relates to a cracking furnace, in particular to a domestic garbage and shale cracking furnace. Background technique [0002] With the development of the national economy, the acceleration of urban construction, the growth of population and the improvement of people's living standards, the output of municipal solid waste has shown a trend of rapid growth. At present, the basic methods of municipal solid waste treatment in various countries in the world mainly include: landfill method, incineration method and composting method. Among them, the composting method has poor waste volume reduction effect, and the process of composting technology is relatively simple, but the investment in foreign technology is huge. Not suitable for our national conditions. The landfill method needs to occupy a large amount of land resources, and it is easy to cause secondary pollution to water and soil. The most important thing is that after the service period...

At present, the basic methods of municipal solid waste treatment in various countries in the world mainly include: landfill method, incineration method and composting method. Among them, the composting method has poor waste volume reduction effect, and the process of composting technology is relatively simple, but the investment in foreign technology is huge. Not suitable for our national conditions

The landfill method needs to occupy a large amount of land resources, and it is easy to cause secondary pollution to water and soil. The most important thing is that after the service period expires, it still needs to invest in the construction of a new landfill, further occupying land resources

Although the incineration method can realize the harmless, reduction, and resourceful treatment of garbage at the fastest speed, and has the advantage of occupying less land resources, but after it is widely adopted in industrialized countries, it appears that the garbage is discharged after incineration. Dioxin has caused serious secondary pollution to the environment, and the United States and Japan have made corresponding control lines for this

At the same time, the investment in incineration equipment is large, and some residues that cannot be completely discarded and overcome by waste incineration still need a second landfill technology
