A trapezoidal high-temperature oxidation chamber for plasma solid waste treatment process

Abstract

The invention discloses a trapezoidal high-temperature oxidation chamber for plasma solid waste treatment process, which comprises a high-temperature oxidation furnace, a pressure control system, an oxygen content control system and a water spray cooling system; A conical structure and a second conical structure at the bottom, and the longitudinal section of the first conical structure is a trapezoidal structure with a narrow top and a wide bottom, and the longitudinal section of the second conical structure is a trapezoidal structure with a wide top and a narrow bottom; the pressure control system The pressure of the high temperature oxidation furnace is controlled to be ‑20~‑30Pa; the oxygen content control system maintains the normal oxygen content of the flue gas outlet; the water spray cooling system controls the normal incineration temperature of the high temperature oxidation furnace. The flow field and heat field in the high temperature oxidation chamber of the present invention are more uniform, the incineration is more stable, the effect is better, and the NO can be significantly reduced. X emission; the setting of double blowers reduces the possibility of interlock shutdown; in terms of structure, the trapezoidal design is also more stable.

Description

technical field [0001] The invention relates to the field of energy-saving and environment-friendly equipment, in particular to a trapezoidal high-temperature oxidation chamber for a plasma solid waste treatment process. Background technique [0002] Hazardous waste refers to waste that is included in the national list of hazardous waste, or identified according to the national hazardous waste identification standards and identification methods, and has hazardous characteristics. With the development of the economy and the improvement of technology, the industrial scale is also expanding, and the hazardous waste discharged from industrial production is also increasing. Hazardous waste is toxic, explosive, flammable, corrosive, chemically reactive, infectious, radioactive and other hazardous characteristics. In view of its environmental risks and threats to human health, hazardous waste has become one of the major environmental problems that our country is facing. At presen...

Problems solved by technology

If the cylindrical design is still adopted, the smoke flow rate will be faster in the lower part and slower in the upper part.

Such turbulence increases the uneven flow rate, which will easily lead to uneven distribution of thermal field in the high-temperature oxidation chamber, local ultra-high temperature, and aggravate the formation of NO X; it is also easy to produce dead-end areas, incomplete combustion of combustible gas, and emissions are not up to standard
