Description

Technical Field

[0001] This utility model relates to the field of nitrogen generators, specifically a temperature control device for a mining membrane nitrogen generator. Background Technology

[0002] A nitrogen generator is a device that uses air as raw material and separates oxygen and nitrogen using physical methods to obtain nitrogen gas. Industrially used nitrogen generators can be classified into three types according to different classification methods: cryogenic air separation, power-sensor separation (PSA), and membrane air separation. Ambient temperature has a significant impact on nitrogen generation efficiency.

[0003] For example, patent CN208948854U discloses a polymer membrane separation nitrogen generator, including an air compressor, a delivery pipe, an air tank, a circular pipe, a filter mechanism, a gas supply pipe, an exhaust pipe a, an inlet pipe, an exhaust pipe b, and a mounting frame; the delivery pipe is connected to the air compressor and the air tank, and a solenoid valve is provided on the delivery pipe; the air tank is provided with a bracket a; a water vapor adsorption layer is provided inside the air tank; the circular pipe is connected to the air tank and the filter mechanism, and the filter mechanism is provided with a bracket b; the mounting frame is equipped with a gas supply pipe that connects the filter mechanism and the separation tank, and a heater is provided on the gas supply pipe; the separation tank is provided with a mounting plate, and the mounting plate is provided with a polymer membrane; the exhaust pipe a is connected to the separation tank and the nitrogen tank; the exhaust pipe b is connected to the exhaust port; and a bracket c is provided at the lower end of the nitrogen tank.

[0004] The aforementioned patent describes a filtration mechanism that uses multiple filter layers to filter air multiple times, effectively removing impurities. Multiple separation tanks also work simultaneously to improve separation efficiency. However, the patent has a drawback: it cannot control the temperature, and ambient temperature significantly affects nitrogen production.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
