Description
Technical Field
The utility model relates to a device of supplementary collection dirt of particulate matter processing before straining.
Background
The air purifier is used as a device capable of improving air cleanliness, and the purpose of purifying air is achieved by absorbing, decomposing or converting various air pollutants through an internal filtering unit.
The mainstream particulate matter filtering technology of the air purifier is as follows: physical interception (using HEPA) and high-voltage electrostatic dust collection technology, wherein the particle size of the particles and the filtering efficiency are in direct proportion in the two technologies, namely the larger the particle size of the particles is, the better the filtering effect is. In order to improve the capture efficiency of the filter unit for the fine particle pollutants, a coalescing module is usually disposed on the air inlet surface of the dust filter to ensure that the fine particle pollutants in the air entering the dust filter can be coalesced into large particles and thus can be easily captured by the dust filter. However, since the inner space of the air cleaner is limited, the time for the dust-containing air to flow from the coalescing module to the dust filter is very short, and although the fine dust particles are processed by the coalescing module, a certain time is required for the coalescing process of the fine dust particles, so that most of the fine particle pollutants are not completely coalesced into large particles when entering the dust filter and then penetrate through the dust filter, thereby seriously affecting the filtering efficiency of the dust filter and failing to further improve the cleaning effect of the air cleaner.
Problems and disadvantages of the prior art:
1. when air is purified, the particle size of particulate pollutants is too small to be easily captured;
2. physical interception (HEPA) technology increases the filtration level of the filter, increasing wind resistance and cost in order to improve the capture efficiency of small particle size contaminants.
3. The high-voltage electrostatic dust collection technology increases the charging time and the capturing time, reduces the wind speed and increases the volume of the air purifier in order to improve the capturing efficiency of small-particle-size pollutants.
