Problems solved by technology

However, due to the continuity of production, the gas booster fan must run continuously for 24 hours. The more gas delivered, the more dust will be attached to the impeller. Once the ash is scaled, the pressure will decrease and the flow rate will decrease. , the unit vibrates and needs to be shut down for inspection and cleaning.
Cause great labor intensity and economic loss
The above-mentioned problems exist in the gas booster fan of the iron and steel complex, which has a great impact on the normal and safe production of production. It is hoped that this problem can be solved through auxiliary measures

Abstract

Disclosed is a gaseous phase scale inhibitor for multiple types of gas booster fans. The gaseous phase scale inhibitor comprises the following components of, by mass, 30%-45% of polyaspartic acid, 5%-10% of diethylenetriamine, 5%-10% of ethylene distearamide, 30%-45% of hexamethylenediamine tetramethylene phosphonic acid and 1% -10% of petroleum ether. The scale inhibitor is added into a blast furnace gas pipeline in front of an inlet of a compressing blower through a metering pump and atomized fast by means of residual temperature of blast furnace gas and kinetic energy of the gas. The atomized scale inhibitor enters a fan cavity channel and makes complete contact with the surface of a fan rotor along with the gas, and the purposes of protection and scale inhibition for the fan rotor and blades in the gaseous (atomized) state are achieved. The gaseous phase scale inhibitor for the multiple types of gas booster fans is suitable for scale inhibition for blast furnace gas, coke oven gas, converter gas and other multiple types of gas booster fans.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy and chemical industry, and in particular relates to a gas phase scale inhibitor used for multi-type gas booster fans. Background technique [0002] The gas booster fan is an important tool used by the gas booster station of iron and steel enterprises to increase the gas pressure and flow rate to meet the needs of users. The chemical composition in the gas is relatively complex, and there is a lot of ash. The converter gas is recovered from the hood, and the dust content after passing through the washing tower, electrostatic precipitator treatment, pipeline transportation, and gas cabinet precipitation basically meets the requirements. However, due to the continuity of production, the gas booster fan must run continuously for 24 hours, and the cumulative amount of gas transported is large, and the amount of dust attached to the impeller is also increased. Once the ash is scaled, t...
