Compressed air drying and purifying system

Abstract

The invention provides a compressed air drying and purifying system that comprises a piston type air compressor, a cooler, an oil-water separator, a screw air compressor, a buffer tank, a U-stage pre-filter, an H-stage activated carbon micro oil mist precision filter, an air dryer and an F-stage precision filter, wherein an inner bin of a cylindrical structure is arranged in the oil-water separator, and the bottom of the inner bin is of a semicircular structure; a filtering piece with a cylindrical structure is mounted in the oil-water separator; the bottom piece is arranged at the bottom of the oil-water separator; liquid in the oil-water separator can be discharged through the bottom piece; a liquid discharging pipeline is arranged on the side edge of the bottom piece. Since the sealingpiece is arranged at the bottom of the bottom piece, when liquid is discharged, residues contained in the liquid can be firstly precipitated, the residues can be precipitated in the sealing piece andcan be conveniently discharged; and if the liquid needs to be independently taken out, the sealing piece can be directly opened, and the liquid can be directly discharged downwards.

Description

technical field [0001] The invention belongs to the technical field of purification systems, and more specifically relates to a compressed air drying and purification system. Background technique [0002] In modern industry, safe and inexhaustible compressed air is the second largest power source next to electricity, and it is also a process gas source with multiple uses. However, the untreated compressed air that contains a lot of dust, condensed water, rust, and oil is the most corrosive, which will deteriorate the rubber, plastic, and sealing materials in the system, block the small holes and filter screens, and cause valve damage. Such action failures or moving parts are stuck and worn, causing pneumatic components to fail and leak, pollute products, and cause metal parts and pipes to rust and corrode. In cold regions, the freezing of water will cause the pipeline to freeze or crack, which will greatly reduce the reliability and service life of the system, and even caus...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a compressed air drying and purification system to solve the problem that when the oil-water separator of the existing compressed air drying and purification system is in use, the residue contained in it cannot be removed when the liquid is discharged. It is impossible to collect the residue for centralized treatment, and when the oil-water separator of the existing compressed air drying and purification system is used, the sealing of the connection end is not good. After long-term use, it is prone to aging phenomenon, thus Problems prone to liquid leakage
