Technical Field
[0001] This utility model belongs to the technical field of nitrogen generation equipment, and in particular relates to a high-efficiency and energy-saving 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. Depending on the classification method—cryogenic air separation, molecular sieve air separation, and membrane air separation—industrial nitrogen generators can be divided into three types. These generators use high-quality imported carbon molecular sieves as adsorbents and employ the pressure swing adsorption principle at room temperature to separate air and produce high-purity nitrogen. Typically, two adsorption towers are connected in parallel, with an imported PLC controlling the automatic operation of imported pneumatic valves. They alternately perform pressure adsorption and depressurization regeneration to complete nitrogen-oxygen separation and obtain the required high-purity nitrogen gas. Therefore, they play an important role in modern industry.
[0003] However, existing nitrogen generators have many problems. First, they are single-function and cannot be connected to other equipment such as refrigeration equipment or vacuum equipment for auxiliary gas treatment during nitrogen generation. As a result, the entire equipment needs to be moved to the location of the above-mentioned equipment for use, which is time-consuming and labor-intensive. At the same time, the entire equipment needs to be moved and transferred manually, which increases the labor intensity and brings many inconveniences.
