Safety electric furnace utilizing waste heat

Abstract

The invention discloses a safety electric furnace utilizing waste heat, and relates to the technical field of waste heat utilization equipment. The safety electric furnace structurally comprises a tank body, wherein an energy-saving mechanism is fixedly connected to the bottom of the inner side face of the tank body, the energy-saving mechanism comprises a motor, the surface of the motor is fixedly connected with the bottom of the tank body, an air control mechanism is fixedly connected to the top of the motor, a water inlet pipe and a water outlet pipe are fixedly connected to the surface of the air control mechanism, and activated carbon is fixedly connected to the bottom of the inner side face of the tank body. According to the safety electric furnace utilizing the waste heat, the problem of how to effectively utilize the waste heat generated by the electric furnace is solved by designing the energy-saving mechanism, when residual gas reaches the connecting wall after passing through the air outlet, water flow is introduced into the connecting wall, and the speed direction of the water flow is perpendicular to that of air flow, so that the heat transfer efficiency is improved more efficiently, in the process, toxic gas generated by smelting is effectively adsorbed by the activated carbon.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization equipment, in particular to a safe electric furnace for waste heat utilization. Background technique [0002] Waste heat is the energy that has not been used in energy utilization equipment under certain economic and technical conditions, that is, excess energy. Waste heat recycling is an important way to improve economy and save fuel. The direct use of waste heat has the following ways: 1 , Preheat air or feed water, use high-temperature flue exhaust, and heat the air entering the boiler and industrial kiln through a high-temperature heat exchanger, which can improve combustion efficiency and save fuel; 2. Dry materials, use various production processes. Exhaust to dry materials and components, such as mud embryos in ceramic plants, mineral materials in smelters, etc.; 3. Production of hot water and steam, using medium and low temperature waste heat to produce hot water and low-pre...
