[Background technique]

At present, the existing air compressor is to install an air filter device with a filtration accuracy of 3 μm at the air inlet end of the compressor. As shown in Figure 1, when the air passes through the filter device, it flows into the intake valve through the intake duct Enter the compressor body for compression, and then discharge the compressed gas to the oil and gas barrel for preliminary separation of oil and gas. After the separation, the gas is separated from oil and gas again through the oil and fine separator. The compressed gas after oil and fine separation flows into the gas cooler for cooling and then output compression Air; while the cooling lubricating oil separated from the oil and gas barrel passes through the oil cooler, is filtered through the oil filter, and then enters the compressor body for circulating cooling and lubrication.

Due to the use of a 3μm primary air filter device, the filter device has defects such as short air filter life, low filtration accuracy, inconvenient cleaning and replacement of the air filter element, and high maintenance costs, which are mainly reflected in the following two aspects:
