[0001] The utility model relates to the technical field of molecular sieve adsorbers, in particular to a molecular sieve adsorber with a regeneration mechanism. Background Art
[0002] Molecular sieve adsorbers are widely used in air separation and purification industries, and are mainly used to remove impurities such as carbon dioxide, acetylene, and water from the air. The working process of molecular sieve adsorbers in the prior art is divided into two stages: adsorption and regeneration. When the adsorber works normally, the airflow enters from the adsorber inlet and flows out from the adsorber outlet through the adsorbent bed.
[0003] The molecular sieve adsorber itself is of fixed size, but the amount of flue gas produced by different enterprises and factories varies. However, the size of the molecular sieve used for installation is a standard size. During use, it is difficult to replace and adjust the molecular sieve adsorber and the molecular sieve filter element according to the size of the molecular sieve filter element, which increases the difficulty of replacing the filter element. The molecular sieve adsorber cannot regenerate the scrapped granular H-type zeolite molecules that have been deactivated in the catalytic reaction and cannot be regenerated to restore their activity, resulting in the scrapped granular zeolite being discarded as solid waste, which is a waste of resources. Summary of the invention

[0006] Preferably, the heating mechanism includes a heating shell, an electric heating ring, a vertical screw, and a fastening nut. The vertical screw is arranged in a ring shape inside the heating shell. The electric heating ring is connected to the outer side of the vertical screw through the vertical screw.

[0011] Compared with the prior art, the utility model has the following advantages:
[0012] 1.

The vertical screw 15 is arranged in an internal ring shape of the heating shell 4. The outer side of the vertical screw 15 is penetrated and connected with the electric heating ring 14. The outer side of the vertical screw 15 is threadedly connected with the fastening nut 16. The heating shell 4 is penetrated and arranged on the outside of the adsorption shell 2.
[0024] In this embodiment, the vertical screw rod 15 clamps the upper and lower sides of the electric heating ring 14 through the fastening nut 16 arranged on the outside, and the electric heating ring 14 of different widths is positioned and height-adjusted according to heating requirements.
[0025] In this embodiment, the adsorption mechanism 9 includes an adsorption shell 2, an outer sealing cover 5, a material barrel body 10, an inner guide groove 11, a molecular sieve filter element 12, a slider 13 and an air intake pipe fitting 7. The outer sealing cover 5 is arranged directly above the adsorption shell 2. The inner guide groove 11 is annularly distributed inside the adsorption shell 2. The outer side of the inner guide groove 11 is connected to the slider 13. The outer side of the slider 13 is connected to the material barrel body 10. The molecular sieve filter element 12 is arranged inside the material barrel body 10. The air intake pipe fitting 7 is symmetrically penetrated on both sides of the material barrel body 10. The slider 13 is used to position the two sides of the material barrel body 10 to adjust the height of the material barrel body 10.
[0026] In this embodiment, the adsorption shell 2 is connected to the outer side of the slider 13 through the inner guide groove 11 opened on the outer side, and the outer side of the material barrel 10 is positioned by the inner guide groove 11 to improve the disassembly and installation efficiency of material barrels 10 of different specifications.

[0028] The actual application of this molecular sieve adsorber with regeneration mechanism includes the following work contents:
[0029] Step 1: The operator connects the air intake pipes 7 on both sides of the bottom of the adsorption shell 2 to the exhaust part of the corresponding equipment. During use, the material barrel 10 is pulled, and the smoke is inhaled and filtered through the through hole opened at the bottom of the material barrel 10, and the slider 13 arranged on the outside of the material barrel 10 is slid on the outside of the inner guide groove 11, and the position of the material barrel 10 is adjusted, and the slider 13 and the inner guide groove 11 are fastened and positioned with bolts;
[0030] Step 2: The operator usually injects the flue gas directly into the interior of the adsorption shell 2, inhales harmful substances in the flue gas through the molecular sieve filter element 12, and discharges the purified flue gas directly through the exhaust pipe 3 set at the top. When it is necessary to regenerate the molecular sieve filter element 12 inside the equipment, install the electric heating ring 14 inside the vertical screw 15, and position the outer side of the electric heating ring 14 according to the width of the molecular sieve filter element 12;
[0031] Step 3: The operator can rotate the fastening nut 16 so that the fastening nut 16 rotates on the outside of the vertical screw 15, thereby adjusting the height of the fastening nut 16, and lift the bottom end of the molecular sieve filter element 12 by the fastening nut 16, and clamp the top end of the molecular sieve filter element 12 by the fastening nut 16, and close the outer sealing cover 5 set at the top end, and use the outer sealing cover 5 to seal the top end of the heating shell 4;
[0032] Step 4: The operator can turn on the electric heating ring 14. The molecular sieve that has been stored for a long time and has absorbed moisture should be regenerated before use. The interior of the adsorption shell 2 is heated by the electric heating ring 14. During the heating process, the moisture inside the molecular sieve filter element 12 flows directly to the interior of the adsorption shell 2. The electric valve 8 can be opened to discharge the liquid directly out of the interior of the device. Drying in a drying oven at 250-300 degrees for more than 4 hours can remove most of the moisture. The molecular sieve filter element 12 inside the material barrel 10 can also be taken out and the molecular sieve filter element 12 is calcined in a calcining furnace at 500-650°C to completely remove the adsorbed organic matter and moisture therein.
[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
