What Is an Air Scrubber?

Gas scrubber, referred to as Scrubber, also known as wet dust collector Lu is a device that uses a liquid to capture dust particles or gaseous pollutants in a gas stream to purify the gas. It can be used to remove both particulate pollutants and certain airborne pollutants. ^[1]

Gas scrubber blast furnace uses gas scrubber to purify gas

The output of a blast furnace in a West German plant is 5000-5500t / day, and the furnace diameter is 11m. The exhaust air temperature is 200-500 degrees Celsius, the gas flow is 370, ooo-450, ooom / h, and the dust content is 15-3og / mn. The first section of the dust removal system is a dry settling chamber, which separates coarse dust particles first. The air stream then passes through two wet dust collectors, where fine particles are removed. After purification, the temperature of the gas is 60 degrees, and the dust content is below 5mg / mn. Dust-containing water is recycled after solid-liquid separation. ^[1]

Gas scrubber oxygen blowing converter uses Venturi scrubber purifier

A plant has two oxygen-blown converters, each with a production capacity of 180t. The dust load of the airflow is several tens of degrees. The dust-containing exhaust gas discharged from the converter first passed through the waste heat boiler, and the gas temperature dropped to about 1000-C, and then passed through the first Venturi scrubber, and the temperature dropped to 70-80%. The gas was saturated with water vapor and about 90% of the dust Was removed. ^[1]

Gas scrubber alloy smelting electric arc furnace uses gas scrubber to purify exhaust gas

The smoke and dust discharged from a sealed 24MW electric arc furnace passes through the safe passage and device, and then enters the tower scrubber, where it cools down, saturates the water vapor and removes coarse dust particles c, and then enters the Venturi scrubber to remove fine dust. 9 Gas passes The water mist collector removes the fine mist and is drawn by the fan to another workshop for reuse. ^{[2] [2] [1]}
