Garbage dual-degradation disposal device

Abstract

The invention belongs to the field of combustible solid garbage disposal equipment, and particularly provides a garbage dual-degradation disposal device. The garbage dual-degradation disposal device mainly comprises an outer furnace body, an inner furnace body and an oxygen supply device, wherein the inner furnace body is arranged in the outer furnace body, and the oxygen supply device is used for supplying oxygen to the inner furnace body. The garbage dual-degradation disposal device has the advantages that operation of low-temperature cracking and high-temperature combustion can be accomplished in the same device, and garbage disposal is easier, more convenient and rapider; the reduced weight of garbage disposal is large, and is greatly larger than that of the prior art; combustion energy of garbage is sufficiently utilized in the whole garbage disposal process, and more energy is saved; tail gas treatment is easy, convenient and rapid, and free of pollution; the garbage does not need to be selected, and garbage disposal is high in applicability; the device is stable in operation, and smoke combustion is thorough and sufficient; the structure is simple, and disassembly and assembly are convenient; the emergency treatment capacity is high, and automatic and auxiliary ignition operation can be achieved.

Description

technical field [0001] The invention belongs to the field of combustible solid waste treatment equipment, and in particular relates to a double-solution treatment device for waste. Background technique [0002] The traditional solid waste treatment method is direct incineration through an incinerator. This treatment method has the following disadvantages: one, the weight reduction of solid waste is relatively low, generally only reaching about 60% to 70%, that is, the weight of the waste after incineration is still 60% to 70% of that before treatment, and the weight reduction The subsequent landfill and other treatment still need to occupy a large amount of land resources. Second, the garbage after direct incineration will be difficult to degrade due to incomplete incineration. Third, the direct emission of smoke and dust from incineration will still pollute the environment again, requiring secondary purification. [0003] The Chinese invention patent application with the...

Problems solved by technology

This treatment method has the following disadvantages: one, the weight reduction of solid waste is relatively low, generally only reaching about 60% to 70%, that is, the weight of the waste after incineration is still 60% to 70% of that before treatment, and the weight reduction The landfill and other treatment still need to occupy a lot of land resources

The disadvantage of this technology is that it needs external heat supply during operation, and the combustion energy of garbage cannot be fully utilized.

At the same time, the treatment conditions are relatively strict, and different wastes need to be classified and processed before subsequent operations can be carried out. The waste substrates to be treated have high requirements and low applicability

Third, the problem of flue gas generated during the treatment process has not been fundamentally solved, and other treatment equipment is still needed for auxiliary treatment to complete the complete harmless treatment of garbage

[0004] To sum up, although a lot of in-depth research and exploration have been done on the cracking treatment of garbage in the prior art, the existing garbage cracking treatment devices still have complex structures, high manufacturing and operating costs, low waste reduction, and still smoke and dust in the tail gas. Disadvantages such as reprocessing
