Method for spraying ash and blowing dust in water cooling process of collected stainless steel slag

Abstract

The invention belongs to the field of steel slag treatment, and in particular relates to a method for spraying ash and blowing dust in water cooling process of collected stainless steel slag. The technical scheme used in the invention relates to a method for spraying ash and blowing dust in water cooling process of collected stainless steel slag. The method comprises the following steps: first, loading steel slag into a slag pot for air cooling in the open air, then putting the slag pot below a dust collection hood for cooling, wherein the cooling water needs to be sprayed in a misty manner to avoid water accumulation on the surface of the steel slag, at the same time a dust collection fan is turned on, so that dust is collected to a deduster along with a dedusting pipe, and when the steel slag is cooled to 70-80 DEG C, the slag pot is sent to a workshop for tipping treatment, and a new slag pot is cooled again. The method has the beneficial effects that dust sprayed in the steel slag water cooling process can be effectively absorbed, and on-site worker operation environment can be obviously improved.

Description

technical field [0001] The invention belongs to the field of steel slag treatment, in particular to a method for collecting stainless steel slag and spraying ash and dust during the water cooling process. Background technique [0002] A large amount of steel slag will be produced during the production process of iron and steel enterprises. With the continuous strengthening of the national environmental protection policy, the treatment of steel slag has become a relatively important event for iron and steel enterprises, especially the treatment of stainless steel slag produced in the process of stainless steel production and smelting is more difficult. In the process of stainless steel slag treatment, in order to speed up the cooling and the turnover of the slag tank, iron and steel enterprises generally adopt the method of pumping water for cooling. Since the water will penetrate into the steel slag along with the cracks on the slag surface during the process of pumping water...

AI Technical Summary

Problems solved by technology

In the process of stainless steel slag treatment, in order to speed up the cooling and the turnover of the slag tank, iron and steel enterprises generally adopt the method of pumping water for cooling. Since the water will penetrate into the steel slag along with the cracks on the slag surface during the process of pumping water, under the action of high temperature, the water will Converted into water vapor volume expansion, it will be sprayed out along the cracks of the steel slag, and the stainless steel slag will be powdered during the cooling process, and will float into the air with the water vapor sprayed out, causing serious environmental pollution and seriously affecting the environment of the work site

Generally, the environment of steel slag pumping and cooling workshops in iron and steel plants is relatively harsh, which has a great impact on the health of workers.
