Description

Technical Field

[0001] The utility model relates to the technical field of pre-filtration, in particular to a pre-filtration device for aerosol particles. Background Art

[0002] Aerosol particles refer to tiny solid or liquid particles suspended in the air. Their size is usually between 0.1 microns and 10 microns. They can come from natural sources (such as dust, pollen and volcanic ash) or human activities (such as industrial emissions, vehicle exhaust and coal burning). Aerosol particles have an important impact on air quality and human health. Some fine particles can be inhaled into the lungs, causing respiratory problems and even adverse effects on the cardiovascular system. In order to prevent aerosol particles from being inhaled into the lungs and other parts of the body, a pre-filter device is needed to reduce the particle load entering the subsequent processing equipment. It is usually located at the front end of the gas treatment system and can effectively remove larger particles to prevent them from damaging or clogging subsequent equipment.

[0003] During the use of traditional aerosol particle pre-filter devices, the filter can only be disassembled and cleaned or replaced individually and cannot be cleaned directly. As a result, when the filter is clogged with impurities, the filtration efficiency is affected, the load on the fan is increased, and even damage is caused, which affects the service life of the aerosol particle pre-filter device.
