Description
Technical Field
The utility model belongs to the technical field of steel slag treatment, and relates to a dust and steam collecting device for a steel slag hot-disintegrating process.
Background
A large amount of steel slag can be generated in the steel smelting production process, and the treatment of the steel slag becomes the main work of resource reuse and environmental protection of metallurgical enterprises. At present, the treatment process of the converter steel slag mainly comprises a hot splashing method, a roller method, a hot stuffy method and a hot stuffy pouring treatment method, wherein the hot stuffy method can meet the requirements of stability and environmental protection of the steel slag performance, and is a main stream method of a metallurgical enterprise at present.
The hot disintegrating process utilizes the waste heat of the steel slag to lead the steel slag to be self-disintegrated and pulverized, and is convenient for the separation of iron and slag, thereby realizing the recovery of iron in the steel slag and the reutilization of slag powder, and the main principle is that the high-temperature steel slag is subjected to water beating and hot disintegrating in a closed hot disintegrating pool, so that the steel slag reacts with water: f-CaO+H2O→Ca (OH) 2; f-MgO+H2O→Mg (OH) 2. In the hot disintegrating process, water generates water vapor when meeting high temperature hot slag, and under the action of high temperature hot pressure, alkaline vapor is mixed with part of dust existing in the slag to diffuse outwards. In the diffusion process, part of the water vapor is condensed into water or falls back into a hot-closed pool along with the condensation of dust particles, part of the dust vapor continuously rises under the action of high-temperature hot pressure and is discharged from the top of the plant, but under the condition that the temperature is lower in winter in the north, part of the water vapor is condensed into small water drops before reaching the top of the plant, stays at a place 1-2 m away from the top of the plant, cannot be discharged from a skylight through hot pressing, wind pressure and the like, and the water vapor is continuously accumulated in the plant, so that smoke in the plant is diffused, and the visibility is very low. This is very dangerous for the crane operator to handle the crane to empty the slag pot. Meanwhile, the water vapor can cause the conditions of stripping between the waterproof layer and the base layer, bulging of the waterproof layer, cracking of the lap joint and the like to occur to the building, and can cause corrosion of columns and roof trusses of the steel structure factory building. Therefore, such dust and steam must be collected and treated.
At present, dust and steam generated by hot sealing are mainly collected by reforming a hot sealing pool cover into a tipping type sealing cover and then connecting an air extractor. The slag disintegrating pool smoke trapping device comprises a first spiral welded pipe and a slag disintegrating pool cover plate, wherein an electric ventilating butterfly valve is fixedly arranged above one end of the first spiral welded pipe, a first dome is arranged above the slag disintegrating pool cover plate, the dome is a smoke trapping cover, and a pipeline bearing is arranged on the first spiral welded pipe, so that a gas collecting cover can swing along with the slag disintegrating pool cover plate to open or close a hot disintegrating pool. Although the structure can collect dust and gas in the slag disintegrating pool after the slag disintegrating pool cover plate is covered, when the slag disintegrating pool cover plate is opened, the slag disintegrating pool cover plate is positioned on one side of the slag disintegrating pool, and cannot effectively collect the dust and gas in the slag disintegrating pool at the moment, so that a large amount of dust and gas can escape into a workshop, and the slag disintegrating pool can work normally and has certain potential safety hazards.
