Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a nitrogen generator with a dust interception function. Background Art

[0002] At the beginning of the 20th century, with the development of industry and the increase in demand for nitrogen, people began to develop equipment that could produce nitrogen on a large scale, namely nitrogen generators. The earliest nitrogen generators separated nitrogen by condensing oxygen in the air, such as using low-temperature condensation to condense oxygen into liquid, leaving a residual part that was mainly nitrogen. With the continuous advancement of science and technology and the continuous expansion of industrial applications, nitrogen production technology is also constantly developing and improving. Modern nitrogen generators usually use efficient technologies such as air separation equipment, which can produce high-purity and large-flow nitrogen, and are widely used in various industrial fields, such as chemical, electronics, food processing, and medicine. Publication number: CN220201445U discloses an explosion-proof nitrogen generator, including a nitrogen generator body, the nitrogen generator body including a base, the top of the base is respectively fixed with a separation tank and a gas storage tank, the bottom of the gas storage tank is fixed with a ring seat, the ring seat is fixed on the base, a pipeline is fixed between the separation tank and the gas storage tank, a vacuum pump is fixedly installed on the pipeline, a movable barrel is movably installed on the ring seat and the gas storage tank, a fixed seat is fixed at the bottom of the movable barrel, and a heat dissipation fan is fixedly installed inside the fixed seat. In this explosion-proof nitrogen generator, after the movable barrel is installed on the gas storage tank, the heat dissipation fan on the top is used to perform secondary cooling of the discharged water, thereby facilitating the cooling of the gas storage tank by water. When water cooling is not used, the heat dissipation fan can be used to cool the gas storage tank. However, in the case of the above-mentioned equipment, there is no device to filter dust when air enters the equipment. During the use of the equipment, dust will enter the equipment through the air inlet, which may cause dust accumulation, blockage or wear inside the machine, thereby reducing the efficiency and life of the equipment. At the same time, dust accumulation inside the equipment may cause safety hazards such as equipment overheating and electrical failure, and may even cause serious accidents such as fire or explosion, which needs to be improved.
