Plasma gasification treatment system of solid organic waste

Abstract

The invention discloses a plasma gasification treatment system of solid organic waste, which comprises a feeding part, a drying device, a gasifier and a synthesis gas purification device, wherein the gasifier comprises a gasification plasma gun, and the synthesis gas purification device comprises a reheating plasma gun. With the adoption of the gasification treatment system, solid waste enters the gasification treatment system through the feeding part, and moisture in the solid waste is evaporated after the solid waste passes through the drying device; then the dried solid waste enters the gasifier, and gasification reaction is carried out on organic substances in the solid waste to produce synthesis gas and a polymer hydrocarbon composite under the action of the gasification plasma gun; and the synthesis gas and the polymer hydrocarbon composite produced by the gasifier enter the synthesis gas purification device, cracking is carried out on the polymer hydrocarbon substances to produce the synthesis gas under the action of the reheating plasma gun, fly ashes in the synthesis gas are removed through settlement of the synthesis gas, and then the purified synthesis gas is output. The system has high gasification efficiency, is stable to run and no-pollution.

Description

technical field [0001] The invention relates to a plasma gasification treatment system for solid organic waste, which is mainly used in the treatment of solid organic waste, and can extract synthetic gas rich in calorific value from solid organic waste, especially suitable for domestic garbage, waste tires, rural biological Solid organic waste such as fuel and low-quality coal belongs to the field of solid waste treatment technology. Background technique [0002] With the rapid development of industrialization and urbanization and the rapid rise of material consumption levels, the generation of solid organic waste is increasing, the resulting environmental pressure and how to improve the quality of urban solid organic waste itself as a resource These problems need to be solved urgently. Solid organic waste has become a thorny problem in urban development. Solid organic waste not only causes public nuisance, but also is a huge waste of resources. Among the annual output of h...

Problems solved by technology

[0005] At present, fixed bed gasification technology, fluidized bed gasification technology, entrained bed gasification technology and ebullated bed waste gasification technology are generally used in gasification treatment. Waste and coal are different in moisture, ash, calorific value, volatile matter and ash melting point, which lead to different problems in the use process, so its use is greatly restricted
