Device for treating solid wastes through plasma gasification melting furnace

Abstract

The invention discloses a device for treating solid wastes through a plasma gasification melting furnace. A horizontally extending main spindle is arranged on a furnace body; the furnace body can be rotatably arranged on a base through the main spindle; a holding cavity is arranged in the furnace body; a feed inlet is formed in the top part of the holding cavity; a fluid outlet of the holding cavity is located on one side of a straight line on which the main spindle is located; a plasma torch is arranged on an installation site; and an electrode stretching into a treatment chamber is arrangedon the plasma torch. Through the optimally designed device for treating the solid wastes through the plasma gasification melting furnace, the plasma torch is used for treating the solid wastes in thefurnace body at high temperature; through the tilting of the furnace body, furnace slags in a fluid state after treatment are discharged through a fluid outlet so as to be conveniently dumped, so thatthe equipment operation cost can be effectively reduced; and the plasma torch treatment high temperature is high, so that gas during the treatment process is sufficiently gasified or combusted, the discharged tail gas is larger than or equal to 1200 DEG C, and the residue of harmful macromolecule gas is reduced.

Description

technical field [0001] The invention relates to the field of harmless treatment of solid waste, in particular to a device for treating solid waste in a plasma gasification melting furnace. Background technique [0002] Solid waste treatment, especially the harmless treatment of hazardous solid waste is a worldwide problem. At present, the commonly used treatment technologies in the world mainly include solidification landfill method, incineration method, and high-temperature melting technology. The solidified landfill method is the simplest and most common method, but this method has significant environmental risks and land resource occupation problems, and has been gradually replaced by other methods. The incineration method is a relatively mainstream treatment method among hazardous waste treatment methods. Although this method can reduce the amount to a certain extent, the residues after treatment, such as fly ash, are still hazardous waste, and solidification and filling...
