Description

A high negative pressure dust and odor removal filter that is easy to clean

Technical Field

The invention belongs to the technical field of air filters, and in particular relates to a high negative pressure dust and odor removal filter that is easy to clean.

Background Art

The filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filtering materials. It purifies the air with low dust content and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room. It is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. There are primary filters, medium efficiency filters, high efficiency filters and sub-high efficiency filters. Various models have different standards and usage efficiency.

Chinese patent CN101332393B discloses an air filter, in particular, a high-voltage electrostatic air filter for efficient sterilization, dust removal and odor removal, which mainly includes a high-frequency transformer and a frame with inherent protective nets on both sides, the air filter is provided with positive and negative electrodes connected to the output end of the high-frequency transformer, the frame is the negative electrode, the positive electrode is placed in the frame, the positive and negative electrodes are filled with insulating material glass fiber, the material used for the positive electrode is a conductive granular activated carbon filter element composed of an aluminum honeycomb panel and granular activated carbon placed in the honeycomb; when used, the high-voltage electrostatic field generated by the filter is a plane, so that the sterilization and dust removal efficiency of the filter is higher; at the same time, the adsorption capacity of the granular activated carbon filter element enables the filter to remove odors and will not fail due to dust clogging.

Existing high-negative-pressure dust and odor removal filters that are easy to clean may become clogged with dust after long periods of use, especially household models, resulting in poor air intake and exhaust effects. However, cleaning is limited by the fact that the filter components are located inside the device, making disassembly, replacement and cleaning more troublesome, and normal filtering cannot be performed before replacement is completed, making it inconvenient to use.

Based on the above-mentioned situation, we found that it is difficult for the high negative pressure dust removal and odor removal filters in the prior art to avoid the above problems at the same time. Therefore, we proposed a high negative pressure dust removal and odor removal filter that is easy to clean and can improve the speed of disassembly and replacement of the filter structure and can also work normally during replacement and cleaning.
