Efficient energy-saving submerged arc furnace structure with cooling function

Abstract

The invention discloses an efficient energy-saving submerged arc furnace structure with a cooling function, and relates to the technical field of submerged arc furnaces. The structure comprises a submerged arc furnace body, a cooling mechanism, an auxiliary heating mechanism and a flow guide exhaust mechanism, wherein the cooling mechanism is arranged on the outer wall of the submerged arc furnace body, the flow guide exhaust mechanism is arranged on one side of the submerged arc furnace body, the auxiliary heating mechanism is arranged on the back face of the submerged arc furnace body, and the submerged arc furnace body comprises a combustion furnace chamber, a heat energy absorption box and a connector. By arranging a water pump, cooling water in a water tank is effectively pumped out and guided into an annular pipe and a supporting guide pipe which are arranged on a water guide support through the effect of a water guide pipe, and then the cooling water is atomized and sprayed out through the effect of an atomization spray head, so that it is guaranteed that the cooling water is evenly sprayed, and then cooling water flows through the furnace wall, so that corresponding heat can be directly taken away, furnace lining erosion is slowed down, metal fatigue of a furnace shell is reduced, the service life of the submerged arc furnace body is prolonged, and the durability of the submerged arc furnace body is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of submerged arc furnaces, in particular to a high-efficiency and energy-saving submerged arc furnace structure with a cooling function. Background technique [0002] Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing and smelting ore, carbonaceous reducing agent and solvent and other raw materials. For important industrial raw materials and chemical raw materials such as calcium carbide in the industry, the load of submerged arc furnace transformers is continuous and stable, the impedance voltage is low, the number of voltage regulation stages is large, the level difference is small, and the overload capacity is strong. It can be divided into two types: on-load and off-excitation voltage regulation. Generally, the first few stages have constant capacity output, and the latter several stages have constant current output. [0003] At prese...
