Description

Technical Field

[0001] The invention belongs to the technical field of nitrogen generators, and in particular relates to a carbon molecular sieve nitrogen generator. Background Art

[0002] Carbon molecular sieve nitrogen generator is a device that uses the adsorption and separation functions of carbon molecular sieve to prepare nitrogen. When nitrogen-containing gas passes through the carbon molecular sieve, nitrogen molecules will be adsorbed on the surface of the carbon molecular sieve to form an adsorption layer. As the gas continues to pass through, the adsorption layer will gradually thicken, causing the speed of the gas passing through the carbon molecular sieve to slow down. At this time, the nitrogen molecules adsorbed on the carbon molecular sieve can be desorbed by reducing pressure or increasing temperature, and discharged through the outlet pipe. During the re-adsorption process, new nitrogen molecules will be re-adsorbed on the surface of the carbon molecular sieve to form a new adsorption layer. Through continuous adsorption and desorption processes, pure nitrogen can be prepared.

[0003] A pressure swing adsorption carbon molecular sieve nitrogen generator is disclosed in the patent with application number 202223130938.4. The application filters impurities by setting a filter screen to prevent impurities from entering the nitrogen making box and increase the service life of the adsorption material in the nitrogen making box. In combination with the prior art and targeting the above application, during the use of the nitrogen generator in the above application, when the gas enters the filter box for filtration, the gas is usually not evenly distributed, resulting in certain limitations when the gas passes through. In addition, when the gas passes through the filter screen and the drying box, uneven distribution will occur, which affects the gas filtration quality, reduces the filtration efficiency, and also affects the practicality of the device. For this reason, we propose a carbon molecular sieve nitrogen generator. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) By setting up the structure with the gas distribution plate, when the device is used to prepare nitrogen, when the gas enters the gas distribution plate, the driving rod drives the gas distribution plate to rotate. During the rotation, the gas is evenly distributed. Since a gas distribution opening with a certain angle is opened at the bottom of the gas distribution plate, the gas can collide with each other when it is blown out. The collision changes the movement direction and speed of the gas and forms gas turbulence. This randomness enables the gas molecules to gradually spread throughout the space. The rotating gas distribution plate can make the gas evenly distributed in the space, so that it can be filtered and dried more evenly through the filter screen and the drying box, ensuring the filtering effect while improving the practicality of the device;

[0017] (2) When the gas passes through the drying box, when the driving rod 1 drives the upper drying box and the lower drying box to rotate, the driving rod 2 is installed through the inner side of the driving rod 1, and the driving rod 1 and the driving rod 2 are rotated in the opposite direction through the action of the gear box. The stirring rod arranged on the driving rod 2 rotates in the opposite direction at the same time, so as to stir the desiccant in the drying box. The stirring can make the dried material uniform. At the same time, when the gas passes through, the gas passing time is increased, so that the gas and the desiccant are better in full contact, thereby ensuring the drying effect. In addition, the double-layer drying box can better play a drying role, thereby improving the practicality and functionality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution: a carbon molecular sieve nitrogen generator has an efficient nitrogen preparation capacity and can meet the industrial demand for nitrogen. At the same time, compared with the traditional deep cold and high pressure nitrogen production process, the carbon molecular sieve nitrogen generator has lower energy consumption, and the carbon molecular sieve nitrogen generator does not produce harmful substances during operation, which is environmentally friendly. A carbon molecular sieve nitrogen production equipment includes a nitrogen production box 100, a filter box 102 is installed on one side of the nitrogen production box 100, and a window 105 is installed on the front surface of the filter box 102. The window 105 is used for disassembly, replacement and observation of the filter screen 106, which is convenient for replacement and cleaning. A driving motor 200 is installed on the top of the filter box 102, and the inner surface of the filter box 102 is provided with a filter box 102. A rotatable driving rod 1 201 and a driving rod 2 202 are installed at one end of the driving motor 200, a rotating block 204 is installed on the inner top of the filter box 102, the driving rod 1 201 and the driving rod 202 are controlled to rotate in reverse through a gear box 304, and an air inlet pipe 104 is installed on the other top of the filter box 102, one end of the air inlet pipe 104 is located on the inner side of the filter box 102 and a rotatable gas distribution plate 203 is installed. When the nitrogen generator in the application is used to make nitrogen, the gas is passed into the air inlet pipe 104 for filtration, and the filtered gas is sent into the nitrogen making box 100 through the ventilation pipe 103, and the required gas is made through adsorption and filtration of the nitrogen making box 100.

[0026] Specifically, the top of the gas distribution plate 203 is provided with an air inlet 206, the bottom of the gas distribution plate 203 is provided with a gas distribution opening 207, and the air inlet 206 is connected with the gas distribution opening 207, the air inlet 206 and the gas distribution opening 207 form a gas distribution pipeline, and two gas distribution openings 207 with opposite angles are provided on each gas distribution pipeline, and the opening angle of the gas distribution opening 207 is thirty-five degrees, and a plurality of gas distribution pipelines are provided in an array on the gas distribution plate 203, driving The rod 201 penetrates the gas distribution plate 203, and an air inlet 206 is provided on the driving rod 201, and a rotating slot 205 is provided on the inner side of the gas distribution plate 203. The driving rod 201 and the gas distribution plate 203 are positioned by the rotating slot 205 and the air inlet 206.

The gas is evenly diffused, and the filtering effect can be guaranteed while better filtering, thereby improving the practicality of the device.
