Description

Technical Field

[0001] This invention relates to the field of molecular sieve technology, specifically to a molecular sieve adsorber with filtration function and easy-to-replace filter screen. Background Technology

[0002] Molecular sieves are materials containing precise and singly arranged micropores that can be used to adsorb gases or liquids. Sufficiently small molecules can pass through the pores and be adsorbed, while larger molecules cannot. Unlike a regular sieve, it operates at the molecular level. For example, a water molecule is small enough to pass through, but molecules slightly larger than it cannot. Therefore, molecular sieves are commonly used as desiccants. A molecular sieve can adsorb up to 22% of its own weight in water. Molecular sieves are frequently used in the petroleum industry, particularly for purifying gases. For example, silica gel can be used to adsorb mercury from natural gas to prevent corrosion of aluminum pipes and other liquefaction equipment. However, existing molecular sieve adsorbers for gas purification often encounter problems when the gas contains a large amount of impurities and dust. These impurities and dust easily clog the micropores of the molecular sieve, reducing its adsorption capacity and thus decreasing the purification effect.

The telescopic block 12 has the ability to extend and retract through the telescopic spring 13.

[0032] A push rod 14 is installed on the telescopic block 12. The push rod 14 is connected to the center rod 15. A sealing plate 16 is installed at the bottom of the center rod 15. The outer diameter of the sealing plate 16 is equal to the inner diameter of the sealing hole 17.

[0036] The working principle of this embodiment is as follows: When using this molecular sieve adsorber with filtration function and easy filter replacement, first move the device to the place where it is needed. It can be connected to the gas supply pipeline through the feed pipe 18, so that the high-pressure gas to be separated can enter into the feed pipe 18, enter the connecting hole 19 through the bottom of the feed pipe 18, enter the sealing hole 17 through the connecting hole 19, and enter the filter screen 4 through the sealing hole 17. The filter screen 4 filters the impurities and dust in the gas, so that the filtered gas enters the filter chamber 2, and then enters the adsorption chamber 25 through the first guide pipe 24. The molecular sieve 27 in the adsorption chamber 25 selectively adsorbs the gas, so that the adsorbed gas enters the storage chamber 31 through the second guide pipe 29 for storage. After the adsorption is completed, the second guide pipe 29 is closed by the one-way solenoid valve 30, the gas in the storage chamber 31 is discharged through the second discharge pipe 32, and the gas adsorbed in the molecular sieve 27 is discharged through the first discharge pipe 28.

[0037] When it is necessary to disassemble the filter screen 4, the first sealing block 8 can be rotated, causing the threaded block 7 to rotate, which in turn causes the connecting rod 6 to rotate on the push plate 5. This causes the connecting rod 6 to rotate the rotating block 21 within the limiting groove 23. Then, the first sealing block 8 is pulled downwards, causing it to lower the connecting rod 6, which in turn lowers the push plate 5. This causes the push plate 5 to gradually move out of the filter chamber 2, pulling the filter screen 4 downwards. The filter screen 4 then causes the sealing head 3 to gradually move out of the filter chamber 2, disconnecting the sealing head 3 from the feed pipe 18. Open the connection so that the top rod 20 no longer presses against the center rod 15, causing the telescopic spring 13 to push the telescopic block 12 upward, so that the telescopic block 12 moves upward on the support rod 11, and the telescopic block 12 drives the center rod 15 upward through the push rod 14, so that the center rod 15 drives the sealing plate 16 to move into the sealing hole 17, sealing the sealing hole 17. Move the filter screen 4 to a suitable position, and remove the sealing head 3 to clean the impurities inside the filter screen 4. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
