Problems solved by technology
[0002] In the past hot and stuffy production process of converter steel slag, a large amount of steam and dust will be generated. If these steam and dust cannot be removed in time, they will accumulate on the top of the workshop building, which will not only affect the sight line of the crane operation, but also bring safety hazards. It will increase the corrosion of the steel structure of the plant itself and the equipment in the plant
The previous air extraction and dust removal equipment cannot solve these problems well, and cannot meet the requirements of modern production for environmental protection

Embodiment
[0029] Embodiment: The present invention well solves the discharge problem of a large amount of steam and dust generated in the hot sweltering process of converter slag. It is an effective method for converter slag hot stuffing process. In the previous process, when the cooling water is sprayed on the surface of the molten converter slag, a large amount of water vapor and dust will be generated; moreover, these water vapor and dust are often suspended in the air. The employees in the workshop are often working in such a harsh environment, causing great hidden dangers to their health problems; at the same time, a large amount of water vapor will erode the steel structure workshop, and dust will accumulate on the roof of the workshop, which will cause the danger of collapsing the workshop; the present invention The problem of safe discharge of steam and dust in this process is well solved.

The invention discloses a rotary steam exhaust and dust removal device for a hot closed delve device, which comprises a rotary device (1), a flue gas collection device (2), a spraying device (3) and an exhaust pipeline (4). The rotary device (1) comprises a driving device (1-1), a turnabout pulley device (1-2) and a supporting device (1-3); the flue gas collection device (2) comprise a gas collection hood (2-1) and a delivery pipeline (2-2); the spraying device (3) comprises a water pipe (3-1) and an atomizing nozzle (3-2); and the exhaust pipeline (4) comprises a metal hose (4-1) and a main exhaust pipeline (4-2). Through the rotary steam exhaust and dust removal device, steam dust at the earlier stage of converter steel slag can be controlled by feeding water and a large amount of steamin the hot closed delve process can be effectively discharged; meanwhile, the device has an integrally upward streamline exhaust structure, so a large amount of high-temperature steam generated in the hot closed delve process can be effectively discharged; in addition, the device has a compact structure, is easy to operate and meets the requirement of hot closed delve production.
Description
technical field [0001] The invention relates to a rotary steam exhausting and dedusting method and device for hot stuffy devices, belonging to the field of environmental protection dedusting equipment. Background technique [0002] In the past hot and stuffy production process of converter steel slag, a large amount of steam and dust will be generated. If these steam and dust cannot be removed in time, they will accumulate on the top of the workshop building, which will not only affect the sight line of the crane operation, but also bring safety hazards. It will increase the corrosion of the steel structure of the plant itself and the equipment in the plant. The previous air extraction and dust removal equipment cannot solve these problems well, and cannot meet the requirements of modern production for environmental protection. Contents of the invention [0003] The object of the present invention is to provide a rotary steam exhaust and dust removal device for a heat stu...
