Dangerous waste heat treatment tank type testing furnace device

Abstract

The invention discloses an experimental electric furnace device for a heat treatment of hazardous wastes, which comprises a sealing heating system, an air course system and a temperature controlling system. The sealing heating system comprises a seal casing of a furnace body, a furnace, a si-mo rod heating system, a high temperature-resistant furnace lining and a furnace door. The air course system comprises an air discharge valve, an air admission valve, a flow counter and a rubber hose. The air admission valve is connected with the flow counter which is connected on the furnace door of the furnace through the rubber hose, and the air discharge valve is connected on the opposite end of the furnace door of the furnace through a pipe. The temperature controlling system comprises a technicalgrade single-chip microprocessor, a voltage transformer and a thermocouple, wherein the thermocouple which is arranged on the rear end of the furnace is connected with the microprocessor, and furtherthe microprocessor is connected with the voltage transformer. The invention adopts a time-temperature feedback system, which realizes that the technical grade single-chip microprocessor can automatically control a heating system, the heating system is kept in an optimum testing state, the temperature in a heat-insulating system of the furnace is rapidly raised to a setting temperature, and seal heating treatment of the hazardous waste can be achieved.

Description

technical field [0001] The invention relates to an electric furnace device for a laboratory, in particular to a box-type experimental electric furnace device for heat treatment of hazardous waste. Background technique [0002] The thermochemical treatment of solid waste, such as incineration, pyrolysis, melting and microwave, is to decompose the waste under high temperature conditions, so that the toxicity of some highly toxic components in it can be reduced, and the volume of the waste can be reduced rapidly and significantly. Useful ingredients are used. Because this method has many advantages mentioned above, at present, the use of thermochemical treatment to realize the treatment or safe disposal of solid waste, especially hazardous waste, is gradually attracting people's attention in China. [0003] During the thermochemical treatment of solid waste, the end products may include acid gases (such as CO 2 , HCL and SO 2 etc.), soot, CO, incompletely burned organic comp...

AI Technical Summary

Problems solved by technology

[0005] (1) Openness: Ordinary test electric furnaces are generally open systems. During the heat treatment process of solid waste, especially hazardous waste, the harmful waste gas generated during the process cannot be collected and treated.

[0006] (2) Low temperature: The rated temperature of ordinary test electric furnaces is generally lower than or equal to 1200°C, which cannot meet the requirements for high-temperature treatment of solid waste

Therefore, ordinary test electric furnaces are not suitable for treating solid waste under complex conditions
