Acetic acid production device based on oil-free screw air compressor

An acetic acid production device based on an oil-free screw air compressor relates to the technical field of chemical safety production equipment and comprises the oil-free screw air compressor, an air heat exchanger, an air buffer tank, an acetaldehyde oxidation tower, a crude acetic acid storage tank, a high-boiling evaporation boiler, a crude acetic acid concentration tower, a diluted acid metering tank and a large diluted acid tank. The oil-free screw air compressor, the air heat exchanger, the air buffer tank, the acetaldehyde oxidation tower, the crude acetic acid storage tank, the high-boiling evaporation pan, the crude acetic acid concentration tower, the diluted acid metering tank and the large diluted acid tank are sequentially connected, the catalytic effect of a catalyst is improved and the service life of the catalyst is prolonged by optimizing the quality of air, the reaction rate is increased, the consumption is reduced, and the production cost is reduced. The acid production rate is improved,
