Description

Technical Field

[0001] The utility model relates to the technical field of a compression device for preparing nitrogen, in particular to a compression device for preparing nitrogen. Background Art

[0002] Nitrogen is a single substance formed by the nitrogen element, with the chemical formula N2. It is a colorless and odorless gas at room temperature and pressure. It can only react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions. It can also combine with oxygen to form nitric oxide under discharge. However, traditional nitrogen preparation and compression devices cannot filter and purify the gas before nitrogen preparation, and cannot compress and store the filtered and purified gas well. It cannot always detect the internal pressure and temperature of the storage tank. When the difference between the external pressure and the internal pressure is large, the gas passage may flow backwards, causing certain damage to the device and causing gas leakage.

[0003] After searching, it was found that a compression device for preparing nitrogen was disclosed in the Chinese patent with authorization announcement 201921980941.0, including: a box body; an air inlet pipe, the air inlet pipe is fixedly installed on one side of the box body; a filter screen, the filter screen is fixedly installed in the box body; an evaporating dish, the evaporating dish is arranged in the box body; an air outlet pipe, the air outlet pipe is fixedly installed on the top of the box body; a mounting pipe, the mounting pipe is fixedly installed on the bottom of the box body; a lifting mechanism, the lifting mechanism is arranged in the mounting pipe, and the lifting mechanism is used to discharge water in the box body.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] The compression device for preparing nitrogen allows gas to enter through an air inlet pipe, and the evaporating dish evaporates and condenses water vapor to fall below, and the water is discharged through the water pressure. During the gas entry process, the air intake and air output may not be able to reach a dynamic balance. When the air intake is large, the internal pressure is large, and the rubber sleeve will be pushed to discharge the water flow, which will also cause a certain amount of gas leakage. The device only has a filtering function and cannot safely compress and collect the gas. Utility Model Content

During the gas entry process, the air intake and air outlet may not be able to reach a dynamic balance. When the air intake is large, the internal pressure is large, the rubber sleeve will be pushed to discharge the water flow, and at the same time a certain amount of gas leakage will be caused. The device only has a filtering function and cannot safely compress and collect the gas.
