High-temperature plasma waste gasification and cracking furnace

Abstract

The invention discloses a high-temperature plasma waste gasification and cracking furnace, which comprises a furnace body, a feeding system arranged on one side of the furnace body, a discharge system arranged at the bottom end of the furnace body and a gas outlet formed in one side of the furnace body, wherein a group of plasma generators is arranged at the lower end of the furnace body; a group of rotating nozzles forming certain included angles with the central perpendicular line of the furnace body is arranged at the upper ends of the plasma generators; a group of temperature thermocouples is arranged on the outer side of the furnace body respectively. According to the high-temperature plasma waste gasification and cracking furnace, arc temperature higher than 5,500 DEG C can be achieved by high-temperature plasmas, the gasification and cracking furnace is heated to more than 1,500 DEG C and even higher temperature to gasify and crack waste to generate synthetic gas to provide heat energy, generate steam, generate power and refine multiple fuels and combustible gas by utilizing the high heat density and high-temperature arcs of the plasma generators, and is applied to any solid waste, secondary pollution is avoided, and discharged glass ash residues are free of toxic substances such as dioxin and heavy metal.

Description

technical field [0001] The invention belongs to garbage treatment equipment, in particular to a high-temperature plasma garbage gasification and cracking furnace. Background technique [0002] my country has a population of more than 1.3 billion, a garbage output of 520,000 tons per day, and a per capita output of 1.02 kilograms per day. All major, medium and small cities are besieged by garbage to varying degrees. At present, sanitary landfill is still the main way to deal with urban waste, supplemented by composting and incineration. Landfill and composting need to occupy a lot of land and space, and pollute the local environment and groundwater at the same time. It is recognized as the last choice for waste disposal. However, waste incineration can achieve reduction and harmless treatment to a certain extent, but it has been questioned by the public due to its potential secondary pollution (such as the production of dioxins and heavy metals). [0003] As early as th...
