Compressed air purification system and using method thereof

Abstract

The invention discloses a compressed air purification system and a using method thereof. The compressed air purification system comprises a preheating heat exchanger and a reactor. A preheating air inlet, a preheating air outlet, a heat exchange air inlet and a heat exchange air outlet are formed in the preheating heat exchanger. The reactor comprises a cylinder and a barrel cover assembly buckled on the cylinder. The middle section inside the cylinder is a reaction region for filling of a catalyst. A reactor air inlet is formed in the portion, above the reaction region, of the cylinder. A reactor air outlet is formed in the portion, below the reaction region, of the cylinder. A sewage draining exit is arranged at the bottom of the cylinder, and a heating pipe is arranged on the cylinder. The reactor air inlet is connected with the preheating air outlet through a pipeline. The reactor air outlet is connected with the heat exchange air inlet through a pipeline. The purification system is simple and reliable in structure, oil-free compressed air can be rapidly and reliably obtained through purification, the using method is simple, manual operations are greatly reduced, the equipment investment is lowered greatly, and the high practicability and market value are achieved.

Description

technical field [0001] The invention belongs to the technical field of compressed air equipment, and in particular relates to a compressed air purification system and an application method thereof. Background technique [0002] All walks of life have a wide demand for air compressors, especially in the medical and food industries, where the cleanliness of compressed air is extremely high, and the compressed air is required to be oil-free, free of particulate impurities and dry. [0003] However, the content of oil, gas, moisture and particulate impurities in the compressed air provided by the existing oil-lubricated air compressors cannot meet the quality requirements, causing pollution to raw materials, products and production processes, and the oil in the compressed air is gasified at high temperature. The formed organic acid will corrode the air compressor and bring harm to the air source device and pneumatic system. [0004] The manufacturing cost of oil-free air compre...

Problems solved by technology

[0003] However, the content of oil, gas, moisture and particulate impurities in the compressed air provided by the existing oil-lubricated air compressors cannot meet the quality requirements, causing pollution to raw materials, products and production processes, and the oil in the compressed air is gasified at high temperature. The formed organic acid will corrode the air compressor and bring harm to the air source device and pneumatic system

[0004] The manufacturing cost of oil-free air compressors on the market is extremely high, but the service life is only half that of oil-lubricated air compressors, which is extremely uneconomical

Therefore, in recent years, purification systems for purifying the compressed air provided by air compressors have emerged, and these purification systems use mechanical separation and filtration reactors and freeze-drying, followed by activated carbon filtration. This purification method not only Many parts, complex structure, and low purification efficiency

At present, the filter reactor of any compressed air purification system on the market has problems such as low filtration efficiency, short service life, frequent maintenance, etc., and the filtered oil needs to be treated separately, otherwise it will cause environmental pollution

The dryer is affected by the working pressure, ambient temperature and the flow and temperature of compressed air, resulting in unstable drying effect.

Therefore, the compressed air purification system not only has low purification efficiency and high power consumption, but also has insufficient filtering effect and cannot provide oil-free, dry and clean compressed air stably. Solving the above problems has become a top priority
