AI Technical Summary
During the steelmaking process, the high-pressure steam generated by the hot-smooth tank needs to be discharged in time, otherwise it will affect the heat-smoothing effect. If air is mixed in, it is easy to generate hydrogen, causing hydrogen explosion and damaging the equipment.
A device for emitting hot steam with a press-heated tank is designed. By setting up a special steam exhaust pipe, the steam does not enter the wet electricity and dust removal to avoid hydrogen explosion. The device includes a steam exhaust pipe, a water collection tank, a drain pipe, a drain main pipe and a hot steam pipe. The steam condensate is discharged into the return well through the drain main pipe.
Through the installation of a special steam exhaust pipeline, steam is prevented from entering the wet electricity and dust removal, and preventing hydrogen explosion; at the same time, steam and condensate are discharged independently, reducing the labor intensity of personnel, saving human resources, and ensuring the smooth progress of the steel slag hot stuffing process.

Abstract
Description
Technical Field

[0002] In the primary treatment workshop of raw material steel slag in a steel plant, there is a pressurized hot stamping tank equipment, which uses waste heat to crush and pulverize the converter bottom slag and then cools it by spraying water. A series of chemical reactions will occur during the hot stamping process, generating a large amount of water vapor and some other gases. The water vapor pressure generated by the pressurized hot stamping tank can reach 0.3 MPa. The water vapor needs to be discharged in time to avoid affecting the hot stamping effect. And once air is mixed in during the hot stamping process, hydrogen is extremely easy to be generated, and hydrogen entering the wet electrostatic precipitator is extremely likely to cause a hydrogen explosion, resulting in equipment damage. After detecting the hot stamping steam, there is no soot in the steam, and the water vapor content reaches 98%. In order to ensure the smooth discharge of the hot stamping steam and avoid hydrogen entering the wet electrostatic precipitator, it is necessary to transform the hot stamping steam discharge system.
