Problems solved by technology

[0003] A large amount of water vapor and smoke will be generated during the hot stuffy process of steel slag, which will cause environmental pollution and cause certain corrosion to the roof and steel structure of the factory building. At the same time, there is a danger of steel slag splashing during the tipping of the slag tank / pan, and the working environment is relatively harsh.
In addition, when the steel slag in the hot stuffy pit is cooled with water, a large amount of steam is generated and diffuses in the factory building, which reduces the visibility in the factory building, and there is a great potential safety hazard especially in the hot stuffy treatment in winter

Embodiment 1

[0024] Such as figure 1 As shown, it shows a mobile cover car 100 according to the embodiment of the present invention, including a cover 1 for covering the hot stuffy pool 8 and a moving part 2 located below the cover 1, and the cover 1 is provided with a communicating mobile cover The interface part 11 between the inside and outside of the car 100 and the opening part 12 for pouring steel slag, the moving part 2 cooperates with the track on the edge of the hot stuffy pool 8, and drives the casing 1 to move on the track.

[0025] The mobile cover car 100 of this embodiment is mainly used in the steel slag heat-stuffing process, that is, pour the high-temperature steel slag (about 1600 degrees Celsius) into the hot-stuff pool 8 to spray water, cover the slag cover, The hot slag in the pool 8 meets water to generate a large amount of saturated steam, which breaks and pulverizes itself. When the mobile cover car 100 of this embodiment is in use, the moving part 2 is driven by a...

Embodiment 2

[0038] Such as image 3 Shown is a method 200 for treating water-containing dust in a steel slag heat-stuffing process according to Embodiment 2 of the present invention, comprising the following steps:

[0039] Step S01: Set the mobile cover car 100 above the hot stuffy pool 8, pour steel slag into the hot stuffy pool 8, and the mobile cover car 100 protects the process of pouring steel slag; Step S02: Use 4 pairs of spraying devices Pour the steel slag into the hot stuffy pool 8 to spray and cool down; step S03: perform dedusting treatment on the generated water-containing fugitive dust; step S04: perform dehydration treatment on the water-containing fugitive dust after dust removal treatment; step S05: discharge after dust removal treatment and dehydration treatment gas.

[0040] Because in the hot stuffy treatment process of steel slag, a large amount of steam will be generated after the high-temperature steel slag is sprayed with water, which also includes various dusts....

Embodiment 3

[0043] Such as Figure 4 As shown, according to the method 200 for treating water-containing dust in the steel slag hot stuffy process of this embodiment, in step S01, before pouring steel slag into the hot stuffy pool 8, the hot stuffy pool 8 can be firstly treated with slag pad S011, and then After pouring the steel slag into the hot stuffy pool, the steel slag in the hot stuffy pool 8 can be raked S012 by using external tools. Because the hot stuffy pool 8 is recycled, in a steel slag hot stuffy process, the steel slag in the hot stuffy pool 8 is sprayed with water and covered with a hot stuffy cover to make the steel slag and water fully react, and after the full reaction, the steel slag is removed from the hot stuffy pool If the interval between the two steel slag hot stuffing processes is short, there may still be residual moisture in the hot stuffy pool 8 from the previous steel slag hot stuffing process, making the environment in the hot stuffy pool 8 humid If the hig...

Abstract

The invention belongs to the technical field of metal smelting, and discloses a movable cover vehicle and a treatment method for water-containing flying dust in a steel slag hot disintegration process. The treatment method for the water-containing flying dust in the steel slag hot disintegration process comprises the following steps that 1), the movable cover vehicle is arranged above a hot disintegration pool, steel slag is poured into the hot disintegration pool, and the movable cover vehicle protects the steel slag pouring process; 2), the steel slag poured into the hot disintegration poolis cooled by spraying by using a spraying device; 3), dust removal treatment is carried out on the generated water-containing flying dust; 4), dehydration treatment is carried out on the water-containing flying dust subjected to the dust removal treatment; and 5), gas subjected to the dust removal treatment and the dehydration treatment is exhausted. The treatment method for the water-containing flying dust in the steel slag hot disintegration process can effectively treat the water-containing flying dust in the steel slag hot disintegration process, so that the treated gas can reach emissionstandards.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to a method for treating water-containing dust in a mobile cover car and a steel slag heat-stuffing process. Background technique [0002] In 2018, my country's crude steel output was about 928 million tons, and the amount of steel slag produced was about 120 million tons or more. In order to facilitate the reuse of steel slag, it is first necessary to carry out high-temperature steel slag cooling pretreatment on steel slag with a slag discharge temperature above 1500°C. All of these methods use water as the medium to cool the high-temperature steel slag, among which the hot stuffing method is the most common. [0003] A large amount of water vapor and smoke will be generated during the hot stuffy process of steel slag, which will cause environmental pollution and cause certain corrosion to the roof and steel structure of the factory building. At the same time, t...
