Description

Catalyst filter module

The present invention is related to filtering equipment, especially a catalytic filter module.

In order to improve the effect of air filtration, many existing commercially available air filtration devices are equipped with a sterilization catalyst in the filter, such as a nanosilver catalyst or a photocatalyst. The catalyst can disinfect and sterilize the air. Purify. However, the most commonly used photocatalyst is to coat the photocatalyst on a carrier, such as a filter or sponge, and then fix the carrier in the flow channel so that air can flow through the carrier when passing through the channel. And the carrier is illuminated so that the photocatalyst coated on the surface can react to achieve the effects of disinfection and sterilization. Although this approach can achieve a certain effect, when the air passes through the flow channel, there will still be a lot of air that does not pass through these photocatalyst carriers, but is surrounded by the carrier and passes through the flow channel. These detour air is not disinfected.

The main purpose of the present invention is to provide a catalyst filter module that can increase the chance of the catalyst carrier contacting air.

In order to achieve the above main objective, the catalyst filter module of the present invention includes a housing with an inlet end and an outlet end, and a flow path is formed between the inlet end and the outlet end. A filter unit is arranged in the flow channel of the casing, and the filter unit includes a plurality of catalyst carriers, and the catalysts are coated on the carriers. The carriers can rotate around a rotating shaft in the flow channel, and the rotating carrier actively increases the chance of contact between the catalyst and the air, and improves the disinfection and sterilization effect of the catalyst.

Preferably, the casing is provided with a fan at the air outlet end for driving the airflow so that air can flow from the inlet end of the casing through the flow channel and flow out to the outlet end

Preferably, a rotating shaft is provided in the housing, and the carriers are plate-shaped, and are arranged on the rotating shaft in a radiating shape with the rotating shaft as the center.

Preferably, the axial direction of the rotating shaft and the flow direction of the air flow in the flow channel are in the same direction.

Preferably, a light-emitting source is provided in the housing to provide light so that the photocatalyst on the carrier can react.
