Abstract

The invention discloses a resistance-type cyclic heating natural gas iron smelting furnace, comprising a waste gas collection and treatment box, an iron smelting furnace heat insulation layer, a burning chamber and a crucible. A fireproof layer is arranged on one side of the crucible and the burning chamber is arranged on one side of the fireproof layer. A waste gas channel is arranged on the topof the burning chamber, an iron smelting furnace is arranged on one side of the chamber, an iron smelting furnace cover is arranged on the top of the iron smelting furnace; an exhaust pipe is arrangedon the top of the iron smelting furnace cover and an exhaust pipe valve is arranged on one side of the exhaust pipe. According to the resistance-type cyclic heating natural gas iron smelting furnace,waste gas can be prevented from being emitted to the atmosphere, influences on the health of workers can be avoided, environment cannot be polluted, andexhaust emission is reduced; natural gas is used to heat iron raw materials, and heating efficiency is high; a heating resistance wire is used to heat the raw materials uniformly and fully, and arrangement of the iron melting furnace thermal insulation layer enables the thermal insulation effect to be the best with little heat loss.

Description

technical field [0001] The invention relates to the field of iron melting, in particular to a resistance circulation heating natural gas iron melting furnace. Background technique [0002] Compared with the Chinese patent application number 201420554394.0, a melting iron furnace includes a furnace body, a waste gas treatment device and a concrete foundation. The concrete foundation is provided with a furnace body groove for accommodating the furnace body. The top and one side are open, and a baffle is arranged on the opening surface. The baffle is hinged on the concrete foundation. The upper part of the concrete foundation is provided with a hollow body and a vent hole. The vent hole connects the furnace body groove with the hollow body. The exhaust gas treatment The device includes a waste gas recovery pipe, a condenser and a suction pump. The air intake end of the suction pump is connected with the hollow body through the waste gas recovery pipe, and the gas discharge end ...
