A compound electric furnace

Abstract

The invention provides a composite electric furnace. The composite electric furniture is characterized by comprising a furnace body, an injection and material collecting device, and temperature lowering and dedusting equipment, wherein the injection and material collecting device is used for cooling high-temperature liquid refractory material and conveying and collecting the refractory material along the same direction, the temperature lowering and dedusting equipment is used for lowering the temperature of dust wastes produced in the furnace body and classifying and recovering the wastes, the injection and material collecting device is connected with a refractory material guiding-out pipe which is arranged on the furnace body, and the temperature lowering and dedusting equipment is connected with a guiding-in pipe at the top part of the furnace body. The composite electric furnace has the advantages that by arranging the injection and material collecting device and the temperature lowering and dedusting equipment, the high-temperature liquid refractory material is recovered in an environment-friendly, energy-saving and high-efficiency way, and dust waste slag is recovered in the environment-friendly, energy-saving and high-efficiency way; by improving the side wall structure of the furnace body, the thickness of the side wall is reduced, and the safety in use is improved.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a composite electric furnace. Background technique [0002] Boilers are usually used when firing heat-resistant materials, and a large amount of dust and waste residues will be generated in the process of firing refractory materials with boilers. If these dust and waste residues are not properly treated, they will pollute the environment and reduce product quality. , if you want to recycle these dust wastes, you need to cool down these dust wastes first, and then recycle them in layers according to the mass proportion to ensure the recovery efficiency. At the same time, you can also recycle the recovered dust. At the same time, heat-resistant materials need to Cooling collection, the traditional way is to set the blowing port in front of the outlet pipe, and then let the outflowing high-temperature liquid refractory material be blown out by the sprayed airflow, cool and condense n...
