Plasma melting furnace with continuous overflow slag discharge function and application thereof

Abstract

A plasma melting furnace with a continuous overflow slag discharge function is proposed, the melting furnace comprises a furnace body, a plasma torch heating system and a bath. A material inlet is arranged on the top of the furnace body, a furnace chamber is coaxially produced in the furnace body, the bath includes a bath body, a continuous overflow slag discharge port and an intermittent clean discharge port, the plasma torch heating system comprises a plasma torch generator and a generator protective heat insulating sleeve which tightly sleeves the outside of the plasma torch generator, andthe plasma torch generator is uniformly arranged along the circumferential direction of the furnace body. At least one plasma torch generator is arranged at a place above the continuous overflow slagdischarge port or at the two sides of the continuous overflow slag discharge port. The melting furnace realizes efficient and rapid melting and continuous overflow slag discharge of a low-calorific-value hazardous waste plasma melting furnace, and finally achieves the purposes of high processing capacity, high thermal efficiency, low labor consumption, high automation degree, low operation risk and low equipment investment of the low-calorific-value hazardous waste plasma melting equipment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a continuous overflow slag discharge plasma melting furnace and its application. Background technique [0002] With the increasing depletion of resources and the continuous improvement of environmental protection requirements, traditional waste treatment technology can no longer meet the needs of pollution control. Low calorific value hazardous waste includes surface treatment waste, electroplating sludge, pickling sludge, spent catalyst, metal smelting and leaching slag, incineration disposal residue, etc., which have the characteristics of low calorific value and high leaching toxicity, and are not suitable for traditional incineration treatment processes. In addition, the traditional incineration process produces a large amount of incineration residue, which contains heavy metals and dioxins, which have been clearly included in the scope of hazardous waste con...
