TECHNICAL FIELD
[0001] The utility model belongs to the device technical field that reduces molecular sieve powder rate, more specifically, it is particularly related to the device that reduces molecular sieve powder rate based on air flow protection. BACKGROUND
[0002] Molecular sieve, as a kind of porous material with unique pore structure and selective adsorption capacity, plays a crucial role in multiple key industries such as chemical industry, petroleum and natural gas. It not only can effectively separate and purify various gas and liquid mixtures, but also can be used as catalyst or catalyst carrier to promote chemical reactions. However, despite the wide application of molecular sieve, its powdering problem has been a technical challenge to be solved. Powdering phenomenon, i.e. the breaking of molecular sieve particles into smaller particles due to friction, collision or mechanical stress during use, not only significantly shortens the service life of molecular sieve, but also seriously damages its original performance.

However, these traditional methods often cannot avoid the problem of high powdering rate. Mechanical vibration may cause severe friction and collision between molecular sieve particles, thus exacerbating the powdering phenomenon. While air flow conveying, although to a certain extent, reduces mechanical contact, improper air flow speed and direction control may also cause unnecessary wear and breakage of molecular sieve.
[0004] Therefore, in view of the above, the existing structure and defects are improved, and the device for reducing molecular sieve powder rate based on air flow protection is provided, so as to achieve the purpose of having more practical value. INVENTION CONTENTS
