Description

Technical Field

[0001] The utility model belongs to the technical field of nitrogen generators, and in particular relates to a purge device for a nitrogen generator. Background Art

[0002] Nitrogen generator refers to a device that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. Nitrogen generators used in industry can be divided into three types according to different classification methods, namely cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation. Nitrogen generator is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. Nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as adsorbent and uses pressure swing adsorption principle (PSA) at room temperature to separate air to produce high-purity nitrogen. Usually two adsorption towers are used in parallel, and the imported pneumatic valve is controlled by the imported PLC to automatically operate, alternately pressurizing adsorption and decompressing regeneration to complete nitrogen and oxygen separation and obtain the required high-purity nitrogen. After nitrogen production, the inner wall of the nitrogen generator needs to be cleaned, and a purge device is required.

[0003] When the existing purge device is in use, it is a manual handheld cleaning mechanism to clean the inner wall of the nitrogen generator. Because the depths of nitrogen generators are different, when cleaning the deeper inner wall, due to the limited length of the arm, the cleaning mechanism cannot be fully extended into the inner wall of the nitrogen generator, which increases the difficulty of cleaning and reduces the cleaning efficiency. Secondly, during the cleaning process, dust is very easy to escape, reducing the air quality of the surrounding working environment. When the operator inhales the air containing dust, it is very easy to cause inflammation of the respiratory tract. Therefore, we provide a nitrogen generator purge device. Utility Model Content
