Technical Field

[0001] This utility model relates to the field of gas separation and compression technology, specifically to an integrated oil-free compressor nitrogen generator. Background Technology

[0002] The integrated oil-free compressor nitrogen generator is a gas separation and compression system that utilizes oil-free compression technology to avoid oil contamination of the gas, as is common in traditional compressors, ensuring high purity output nitrogen. This equipment efficiently separates nitrogen from the air using technologies such as pressure swing adsorption (PSA) or membrane separation, while also incorporating gas purification and drying functions to further improve nitrogen quality. The intelligent control system enables the equipment to automatically adjust operating parameters, ensuring stable and efficient production. It is widely used in laboratories, electronics manufacturing, chemical industries, and other industries with high nitrogen requirements.

[0003] Existing integrated oil-free compressor nitrogen production equipment generates waste gas after nitrogen production. This waste gas contains oxygen, carbon dioxide, etc. Usually, this type of waste gas is directly discharged through pipelines, especially carbon dioxide. However, repeated direct discharge of carbon dioxide can easily cause certain pollution to the environment and affect human production and life.

[0004] In view of this, we propose an integrated oil-free compressor nitrogen generator. Utility Model Content

[0010] As a further improvement to this technical solution, the connecting rod passes through the top of the separation box and extends to the outside of the separation box, and a sealing ring adapted to the diameter of the connecting rod is provided at the contact position between the connecting rod and the top surface of the separation box.

[0011] As a further improvement to this technical solution, the amine solution recovery assembly includes a water outlet pipe that is inserted through one side of the separation tank. A water pump is installed at the bottom of the water outlet pipe, and the water outlet pipe is installed at the output end of the water pump. A water delivery pipe is installed at the input end of the water pump, and the water delivery pipe extends into the inside of the conversion tank. Support columns are fixedly connected to the bottom of the water pumps on both sides of the water delivery pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this integrated oil-free compressor nitrogen generator, the oxygen and carbon dioxide in the exhaust gas are separated by the exhaust gas separation component and the amine solution injected into the separation box.
