Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen production, in particular to a pressure swing adsorption nitrogen production and drying integrated device. Background Art

[0002] The principle of nitrogen production by pressure swing adsorption is to produce nitrogen through the different adsorption amounts of oxygen and nitrogen in the air by the adsorbent (carbon molecular sieve) at different pressures. When the pressure increases, a large amount of oxygen is adsorbed, and the product nitrogen passes through the bed. When the pressure decreases, the adsorption amount of oxygen decreases, and the adsorbed oxygen is desorbed and discharged. The adsorbent is the core part of the nitrogen production equipment. Excessive water and oil in the compressed air will cause the adsorption effect of the adsorbent to decline.

This pressure swing adsorption nitrogen making device, through the filtering mechanism, allows the impurities in the air to be blocked by the filter before the air enters the pressure swing adsorption nitrogen making machine body, thereby improving the quality of the air entering the pressure swing adsorption nitrogen making machine body, and people can control the rotation of the hand wheel to make the two threaded rods rotate simultaneously under the transmission of the two connecting gears and the chain, thereby driving the frame to move, so that the clean filter enters the interior of the filter box, and the dirty filter is separated from the interior of the filter box. The operation is simple and quick, so that people can clean the dirty filter without shutting off the air supply.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0034] Working principle: When in use, the gas in the gas storage tank 2 enters the drying box 3 through the connecting pipe 5, and in this connecting pipe 5, it will exchange heat and cool down with the coolant in the cooling cylinder 6, so that the water vapor contained in it will condense, which is convenient for it to be absorbed and dried by the desiccant 403. At the same time, the circulating water pump 10 can be started, and the circulating water pump 10 absorbs the coolant into the cooling cylinder 6 through the return pipe 11. The coolant enters the serpentine cooling pipe 12 and then flows back to the cooling cylinder 6 through the water pipe 13. At the same time, multiple cooling fans 16 can be started, and the multiple cooling fans 16 blow air to the serpentine cooling pipe 12 to dissipate heat, so that it can quickly cool down and facilitate its cooling. After that, the gas enters the cooling cylinder 6. After being dried, the gas enters the two filter boxes 18 in turn through the first air supply pipe 20.

When it is necessary to clean the filter screen 25, it is only necessary to pull the two synchronous plates 30. The synchronous plate 30 pulls the locking rod 28 to move through the pull rod 29 and squeezes the spring 31 at the same time. When the locking rod 28 is disengaged from the fastening groove 26, the mounting block 24 can be pulled out. At this time, the filter screen 25 can be cleaned. If installation is required, the reverse operation can be performed.
