[0002] The nitrogen compressor has a working pressure range of 300 Mpa for liquids and 90 Mpa for gases. It is divided into single-shaft multi-stage type and double-shaft four-stage type according to the type of shaft. Due to its many characteristics such as a large working pressure range, a wide flow range, easy control, automatic restart, safe operation, and energy saving, it has been widely used.

[0003] The existing Chinese utility model patent with the reference publication number of CN213598137U discloses an improved low-pressure nitrogen compressor, including a housing. One side of the outside of the housing is connected with a clamping block. One side above the clamping block is fixedly connected with a pressing plate. A sponge pad is arranged around the housing below the clamping block. A telescopic joint is arranged below the sponge pad. An air inlet is arranged above the housing. The lower part of the air inlet is communicated with an air inlet cavity. One side inside the air inlet cavity is fixedly connected with a clamping ring. One end inside the clamping ring is fixedly connected with a bag-type dust collector. One side above the air inlet cavity is provided with a ventilation port. A first filter screen is fixedly connected inside the ventilation port. One end of the ventilation port extends into the filter chamber. A plurality of filter plates are fixedly connected inside the filter chamber. A plurality of filter cotton is arranged on the surface of the filter plates. By setting the bag-type dust collector and multiple filtering structures, during use and replacement, only the bag-type dust collector needs to be replaced regularly, which is convenient for maintenance and saves production costs.

[0004] During long-term use, the temperature of the existing low-pressure nitrogen compressor will rise, and the heat dissipation effect of the existing low-pressure nitrogen compressor is not good. When the equipment operates at a high temperature, it will cause an increase in equipment power consumption. Moreover, the existing low-pressure nitrogen compressor is not convenient for dehumidifying the fed nitrogen, thus increasing the load of the nitrogen compressor. Content of the Utility Model
