[0002] Adsorption dryer is the abbreviation of heatless regenerative adsorption dryer, which is a compressed air purification equipment. Adsorption dryer uses the property of adsorbent to selectively adsorb certain components to adsorb moisture in compressed air to achieve the purpose of drying. Since the adsorbent will reach saturation equilibrium after a certain period of adsorption, it is necessary to regenerate with dry gas to restore the adsorption and drying capacity. When the adsorption dryer is in use, air needs to be sucked into the machine to dry it. Therefore, it is necessary to design an air intake guide structure to guide the air intake to facilitate the use of the adsorption dryer.

[0003] China Utility Model Patent Publication No.: CN 209865683 U, discloses: an air intake guide device for an adsorption tower of a dryer, which can be arranged in the air inlet of the adsorption tower of the dryer. When the compressed air enters the adsorption tower, it first acts on the air flow diffusion device, and then the air flow diffusion device makes it evenly distributed in the tower cavity, ensuring that the air flow passes through the adsorbent layer evenly, improving the adsorption effect, extending the service life of the molecular sieve, and saving material costs. However, the air intake guide device for the adsorption tower of the dryer is not designed with a sealing structure, and the air tightness is low.
