Hollow cylindrical garbage microwave pyrolysis furnace

Abstract

The invention belongs to the field of garbage microwave pyrolysis, and relates to a hollow cylindrical garbage microwave pyrolysis furnace used for pyrolyzing household garbage, plant straw, sludge, sewage and the like and recycling lysate. The hollow cylindrical garbage microwave pyrolysis furnace is composed of bin covers, bin bodies, discharging ports, feeders, dischargers, a pyrolysis gas outlet pipe and a safety valve. The hollow cylindrical garbage microwave pyrolysis furnace is a closed running system, garbage is heated through microwaves and pyrolyzed into combustible gas and solid residues in a high-temperature and high-pressure environment, the combustible gas and the solid residues are recycled separately, and then recycling and harmlessness of garbage treatment are achieved. According to the hollow cylindrical garbage microwave pyrolysis furnace, the problem of contradiction between the microwave penetration distance and large-volume pyrolysis bins is solved by adopting thehollow cylindrical structure according to the microwave characteristics, therefore, the volume of the pyrolysis bins is increased, the garbage pyrolysis amount is increased, and large scale of garbage pyrolysis is achieved.

Description

technical field [0001] The invention belongs to the field of microwave cracking of garbage, and relates to a hollow cylinder microwave cracking furnace for garbage, plant stalks, sludge, sewage, etc., and recovering cracked products. Background technique [0002] Garbage disposal is a worldwide problem. The existing garbage disposal methods mainly include landfill, composting, incineration and microwave cracking of garbage. Although these methods have their own advantages, they also have obvious defects and deficiencies. [0003] 1. Landfill method: The landfill method has defects such as occupying a large amount of land resources, polluting the environment, and gradually reducing its applicable value. [0004] 2. Garbage composting method: Garbage composting method is difficult to control the secondary pollution caused to the environment during the composting process, and there are problems such as insufficient utilization of organic matter, complex fertilizer components, a...

AI Technical Summary

Problems solved by technology

[0003] 1. Landfill method: The landfill method has defects such as occupying a large amount of land resources, polluting the environment, and gradually reducing its applicable value.

[0004] 2. Garbage composting method: Garbage composting method is difficult to control the secondary pollution caused to the environment during the composting process, and there are problems such as insufficient utilization of organic matter, complex fertilizer components, and small reduction

[0005] 3. Garbage incineration method: the cost of using incineration to treat garbage is high, and the exhaust gas cannot be discharged up to the standard

However, due to the constraints of microwave characteristics and technical factors, the existing microwave cracking equipment has shortcomings such as small scale, low output, and complicated cracking devices, and it is impossible to realize the large-scale microwave cracking of garbage.
