Abstract

The invention discloses a steam noise-free diffusion system of an RH refining furnace. The system comprises a steam drum and a booster vacuum device connected to the steam drum; the booster vacuum device comprises a steam booster pump and a condenser for spraying condensed water inside, wherein the steam booster pump is connected with an air outlet of the steam drum, and a steam inlet of the condenser is connected with an air outlet of the steam booster pump; and a diffusion pipe of the steam drum is connected to an inlet of the condenser. According to the application, the diffusion pipe of the steam drum is connected with the inlet of the condenser, thus directly leading the exhaust gas of the steam drum to the condenser which is arranged in a closed way, and the condenser can reduce, isolate and eliminate high decibel noise generated during diffusion, and realize safe and harmless diffusion.

Description

technical field

[0001] The invention relates to the technical field of steelmaking, and more specifically relates to a noiseless release system for RH refining furnace steam. Background technique

[0002] RH system equipment is a secondary refining process equipment for molten steel used to produce high-quality steel. The entire molten steel metallurgical reaction is carried out in a vacuum tank lined with refractory lining. The lower part of the vacuum tank is two dipping pipes with refractory lining, and the upper part is equipped with hot bending pipes. The pumped gas is discharged out of the factory building through the hot elbow through the gas cooler to the vacuum pump system.

[0003] At present, the steam drum steam release method of the RH furnace vacuum pump system generally used at home and abroad directly releases the steam into the atmosphere in the plant through the release pipe attached to the steam drum. During the release, there is a phenomenon of high noi...
