Problems solved by technology

[0002] Converter steel slag slag produces a large amount of hot water. Since the slag water has many impurities and is easy to scale, conventional waste heat recovery equipment cannot recover the waste heat of the slag water. Therefore, the heat in the hot water of steelmaking slag has long been It has not been effectively utilized. The current heat treatment method for stuffy slag water is direct discharge, which not only causes a huge waste of heat sources, but also brings huge economic losses to enterprises, and seriously pollutes the environment, aggravates the greenhouse effect, and destroys the earth environment in which human beings live. , causing serious social pollution

Abstract

The invention discloses a disintegrating slag afterheat utilizing system. The disintegrating slag afterheat utilizing system comprises a disintegrating slag tank, wherein a deslagging port at the bottom of the disintegrating slag tank is communicated with a slag sluice, the disintegrating slag tank is communicated with the top of the slag sluice through a steam discharge pipe, the slag sluice is communicated with a sedimentation tank, an overflow baffle plate is arranged in the sedimentation tank, a hot water supplying and feeding pipe is arranged in the sedimentation tank and is connected with a heating water heat exchange device which is communicated with a cold water pond, a cold water supplying and feeding pipe is arranged in the cold water pond and is connected with the disintegrating slag tank, a spraying branch pipe is arranged on the cold water supplying and feeding pipe and is connected with a spraying pipe in the slag sluice, and the heating water heat exchange device is connected with a heating unit. The disintegrating slag afterheat utilizing system has the advantages of being free of influence of impurities in disintegrating slag water, being capable of recycling heat in disintegrating slag water, being contributed to saving of energy sources, reducing the pollution of iron and steel enterprises to environments, and recycling heat for heating so that the heating expenses of enterprises are saved.

Description

technical field [0001] The invention relates to a kind of stuffy slag equipment for steelmaking, in particular to a stuffy slag waste heat utilization system. Background technique [0002] Converter steel slag slag produces a large amount of hot water.
