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
The invention belongs to the slag process field, specifically is a kind of stainless steel slag method that process of cooling sprays grey airborne dust of fetching water of collecting.
Background technology
To supervene big steel slag in iron and steel enterprise's production process; along with the continuous enhancing of country to Environment Protection Policy; slag is treated as the major issue of an outbalance of iron and steel enterprise, and especially the stainless steel slag intractability of stainless steel production smelting process generation is bigger.In the stainless steel slag treating processes, cool off and the slag ladle turnaround speed in order to accelerate, the general method that adopts the cooling of fetching water of iron and steel enterprise, because water can penetrate into slag inside along with top of the slag crack in the process of fetching water, under action of high temperature, water is converted into the water vapour volumetric expansion, will spray along the slag crack, meeting efflorescence in the stainless steel slag process of cooling, along with water vapour ejection air-flow flies away in the air, environmental pollution phenomenon is very serious, has a strong impact on the environment of operation field.The slag of the general Steel Plant cooling workshop condition of fetching water is all comparatively abominable, and is bigger to the healthy influence of workman.
Summary of the invention
The present invention aims to provide the fetch water method of the grey airborne dust of spray of a kind of effective collection stainless steel slag, utilize fetch water, dust collection cover collects the dust that sprays in the stainless steel slag process of cooling, reduces environmental pollution, improves workman's operating environment.
Technical scheme used in the present invention is a kind of stainless steel slag method that process of cooling sprays grey airborne dust of fetching water of collecting, at first the slag slag ladle of packing into is carried out air cooling in the open, be positioned over the cooling of fetching water under the dust collection cover then, water coolant need be vaporific sprinkling, avoids the slag surface area water, opens dust collecting fan simultaneously, allow dust collect in the fly-ash separator with cleaning shaft, treat that slag is cooled to 70-80 ℃, slag ladle is sent into the workshop processing of tumbling, cool off new slag ladle more again.
The invention has the beneficial effects as follows: can effectively absorb the dust that slag is fetched water and sprayed in the process of cooling, can obviously improve workman's execute-in-place environment.
Description of drawings
Fig. 1 of the present inventionly sprays the device synoptic diagram of grey airborne dust for collecting the stainless steel slag process of cooling of fetching water.
Embodiment
At first the slag slag ladle of packing into is carried out air cooling in the open, then as shown in Figure 1, be positioned over the cooling of fetching water under the dust collection cover, water coolant need be vaporific sprinkling, avoids the slag surface area water, opens dust collecting fan simultaneously, allow dust collect in the fly-ash separator with cleaning shaft, treat that slag is cooled to 70-80 ℃, slag ladle is sent into the workshop processing of tumbling, cool off new slag ladle more again.
Claims (1)
1. collect the stainless steel slag method that process of cooling sprays grey airborne dust of fetching water for one kind, it is characterized in that: at first the slag slag ladle of packing into is carried out air cooling in the open, be positioned over the cooling of fetching water under the dust collection cover then, water coolant need be vaporific sprinkling, avoids the slag surface area water, opens dust collecting fan simultaneously, allow dust collect in the fly-ash separator with cleaning shaft, treat that slag is cooled to 70-80 ℃, slag ladle is sent into the workshop processing of tumbling, cool off new slag ladle more again.
