Low-temperature ozone waste pyrolysis treatment device and method

Abstract

The invention discloses a low-temperature ozone waste pyrolysis treatment device. The low-temperature ozone waste pyrolysis treatment device comprises a low-temperature ozone waste pyrolysis furnace and an ozone generator. Through ozone combustion supporting, the low-temperature ozone waste pyrolysis treatment device can accelerate the ashing process of household waste, greatly improve the waste treatment efficiency, reduce the waste treatment cost, achieve volume and quantity reduction of household waste, avoid secondary pollution to the environment, achieve low investment, zero pollution andzero emission of household waste.

Description

Technical field: [0001] The invention relates to the technical field of domestic waste treatment, in particular to a low-temperature ozone waste pyrolysis treatment device and a method thereof. Background technique: [0002] In recent years, with the development of Chinese society, the pace of urbanization and new rural construction has been accelerating, and the urban and rural population is increasingly living in a densely populated direction. A large amount of domestic waste generated in daily life pollutes the living environment more Serious, and has the characteristics of large amount of garbage, complex types of garbage, and few recyclable resources, resulting in greater difficulty and higher processing costs. [0003] There are four main domestic waste disposal methods at home and abroad: [0004] One is the landfill method, where the garbage is buried below the surface. The technical feature of the landfill method is that it is easy to operate and can handle most ty...

Problems solved by technology

[0004] One is the landfill method, where the garbage is buried below the surface. The technical feature of the landfill method is that it is easy to operate and can handle most types of garbage, but it has the disadvantages of large area occupation and serious secondary pollution.

[0005] The second is the composting method. The garbage is biodegraded by composting. The technical feature of the composting method is low cost, but it can only process domestic waste that can decompose organic biomass, and the application area is narrow and the treatment cycle is long. , the methane gas produced by garbage fermentation is also a fire and explosion hazard, and it will cause a greenhouse effect when discharged into the atmosphere, and will produce unpleasant odors

[0006] The third is the incineration method, which incinerates the garbage to achieve the purpose of volume reduction, volume reduction and harmless treatment. At the same time, the heat generated during the incineration process can be used as a resource, but auxiliary energy such as electricity and fuel oil are required during combustion; If the incineration conditions are not properly controlled, highly carcinogenic substances such as dioxins will be produced, there will be smoke pollution problems, and the investment in equipment will be huge

[0007] The fourth is the high-temperature cracking method, which mainly adopts the "external heating" indirect heating method. The heating process consumes a lot of energy, the cracking product has poor recycling and utilization, the recycling level is low, the recycling benefit is not obvious, and it is easy to cause secondary pollution to the environment.

[0008] The above methods all have limitations and the risk of secondary pollution, and the resource recovery rate is low in the process of processing, the benefits are not obvious, and the process requires more external energy
