Abstract

The invention discloses an electric melting plasma moment composite furnace device and method thereof for treating dangerous waste materials, and relates to the technical field of harmlessness of dangerous materials. The technical problems that the quantity of harmful components in smoke discharged by an existing furnace body for treating the dangerous waste materials is still large, and the working efficiency of the furnace body is low are solved. The device comprises an electrode for heating materials at the bottom of the furnace body, the electrode is vertically and movably arranged on the furnace body, and the electrode is driven up and down through a vertical linear driving mechanism arranged on one side of the furnace body so as to adjust the distance between the bottom end of the electrode and the bottom of the furnace body. The height of the electrode can be adjusted through the vertical linear driving mechanism, an electrode heating area can be located in the center of a melt, the bottom temperature is guaranteed, the height position of the electrode can be adjusted according to the thickness of a metal deposition layer, therefore the frequency of shutdown and metal discharging operation is reduced, and the dangerous waste treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of hazardous materials, and more specifically relates to the technical field of an electric melting plasma moment compound furnace device and a method for treating hazardous waste materials. Background technique [0002] When recycling hazardous waste such as automobile oil filter elements, liquid crystal display glass, paint buckets, waste oil, and waste liquid, they are mainly incinerated in rotary kilns, and the residues after incineration in rotary kilns still belong to the category of hazardous waste. Therefore, Generally, it is further processed by electric furnace melting, plasma gasifier gasification, etc. [0003] Although the existing electric furnace melting can solve the problem of vitrification of the residue, the harmful gas generated during the melting process, and the direct discharge of harmful gas will pollute the atmosphere, so it needs to be further processed to be h...
