Low energy consumption iron-making equipment free of environmental pollution

Abstract

The invention discloses low energy consumption iron-making equipment free of environmental pollution. The low energy consumption iron-making equipment comprises a furnace body. A dust removing device,a waste heat recycling device and a cooling device are arranged on the furnace body; the dust removing device comprises an air outlet formed in the furnace body; the air outlet is connected with an air outlet pipeline; the air outlet pipeline is connected with a bag-type dust remover, a desulfurization dust remover and a treatment device; the waste heat recycling device comprises a cold water pool, a recycling pool and a hot water pool; a cold water pipeline is connected between the cold water pool and the recycling pool; a hot water pipeline is connected between the recycling pool and the hot water pool; the air outlet pipeline penetrates through the recycling pool; the cooling device comprises a cooling wall; the cooling wall is fixed in the furnace body; a water inlet of the cooling wall is connected with a water suction pump through a pipeline; the water suction pump is fixed in the cold water pool; and a water outlet pipeline is connected between a water outlet of the cooling wall and the hot water pool. Poisonous and harmful gas in waste gas can be filtered out, atmospheric pollution is reduced, heat can be recycled, and energy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a low energy consumption and non-environmental pollution ironmaking equipment. Background technique [0002] important link in steel production. This method was developed and improved by ancient shaft furnace ironmaking. Although many new ironmaking methods have been researched and developed by various countries in the world, the iron produced by this method still accounts for more than 95% of the world's total iron production because of its good technical and economic indicators, simple process, large production volume and high labor productivity. . The exhaust gas discharged from the ironmaking furnace contains carbon dioxide, carbon monoxide, dust, sulfur dioxide (a small amount) (sulphur in coal) and nitrogen oxides (nitrogen in coal). With the increase of exhaust gas emissions, far Exceeding the ability of the atmosphere to clean itself, thereby destroying...

Problems solved by technology

Existing ironmaking equipment generates a lot of heat during the ironmaking process, and a large part of the heat is lost without effective use, which greatly wastes energy. In addition, in the production of blast furnace ironmaking, many equipment need to be water cooling
