Reverse air circulation purifier structure

This creation relates to a purifier structure, and more particularly to a reverse flow loop purifier structure.

The activated carbon adsorbent in the air purifier is mainly for adsorbing harmful substances in the air, and impregnating special substances thereon, and purifying the specific harmful substances such as VOCs, SOx, NOx, etc., and can be divided into granular and Honeycomb structure. As for the adsorbent of the honeycomb structure, one of them is a solid cylindrical structure, and a plurality of air flow passages parallel to each other are formed in the longitudinal direction of the cylinder. The air to be purified enters the adsorbent from one end of the cylinder, and the harmful substances are thus adsorbed by the activated carbon during the passage through the gas flow passage, and finally the adsorbent is removed from the other end of the cylinder to become clean air.

The adsorbent of the honeycomb structure has the advantages of low wind resistance coefficient, can greatly reduce the wind pressure demand, and achieve the advantages of low noise and low energy consumption, but it is easy to pass the air flow fast, and the area of contact between the air and the activated carbon is small. And the adsorption effect is greatly reduced.

The conventional improvement method is to reduce the pore size of the gas flow channel or increase the overall length of the adsorbent, and overcome the problem of poor adsorption efficiency by increasing the time and opportunity for the air to contact with the activated carbon. However, narrowing the airflow path aperture results in poor manufacturing yield of the honeycomb structure, and increasing the overall length of the adsorbent has a problem of poor space utilization.

There is another improvement method, which is to seal one end of the half air flow passage, and the other end of the other half air flow passage is also sealed, so that after the air enters the air flow passage, it can only flow out from the adjacent air flow passage. However, such a design method can significantly increase the drag coefficient, so that the air volume is greatly reduced, and there is also a problem that the air at the sealing hole does not flow and the cycle efficiency is deteriorated.

In view of this, there is a need to propose a solution to solve the above problems.

The purpose of this creation is to provide a reverse flow loop purifier structure.

In order to achieve the above object, the reverse flow loop purifier structure of the present invention comprises: a honeycomb adsorbent having a columnar structure, the honeycomb adsorbent having a first end, a second end and a ring side, wherein The first end is opposite to the second end, and the annular side is connected to the first end and the second end.
