Waste heat power generation system matched with submerged arc furnace

Abstract

The invention relates to the technical field of submerged arc furnace matched waste heat power generation, and discloses a submerged arc furnace matched waste heat power generation system. The waste heat power generation system matched based on the submerged arc furnace comprises a submerged arc furnace combustion system and a steam turbine power generation system, the submerged arc furnace combustion system is used for providing heat for the whole system, the provided heat pushes the steam turbine power generation system to work, and the steam turbine power generation system is used for recycling heat of the whole equipment for power generation. The flue gas treatment system is connected with the submerged arc furnace, so that waste gas and waste materials generated when the submerged arc furnace works are treated, it is guaranteed that the submerged arc furnace does not pollute the environment when working, and the problems that in the working process, a waste heat power generation system matched with the submerged arc furnace is large in power consumption and serious in pollution are mainly solved; the waste heat power generation system matched with the submerged arc furnace can be ensured to recycle water resources in the using process through the sewage treatment system.

Description

technical field [0001] The invention belongs to the technical field of waste heat power generation for submerged arc furnaces, in particular to a waste heat power generation system for submerged arc furnaces. Background technique [0002] Submerged arc furnace, also known as electric arc furnace or electric resistance furnace, is mainly used for reducing and smelting ore, carbonaceous reducing agent and solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. [0003] The submerged arc furnace consumes a lot of electricity when reducing and smelting ore, and the economic cost is high. Moreover, the submerged arc furnace will emit a large amount of heat energy when it is working. The traditional submerged arc furnace cannot recover the emitted heat, w...

AI Technical Summary

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a submerged arc furnace supporting waste heat power generation system, which effectively solves the problem that the submerged arc furnace needs to consume a large amount of electricity when reducing and smelting ore, the economic cost is high, and The submerged arc furnace will emit a large amount of heat energy when it is working. The traditional submerged arc furnace cannot recover the emitted heat, which will waste a lot of recyclable energy and cause economic losses.
