Description

Air purifier with auxiliary dust collection function for particulate matter treatment before filtration

Technical Field

The utility model relates to an air purifier 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 particulate matter filtering technology of the main air purifier is as follows: physical interception (use HEPA) and high-voltage electrostatic precipitation technique, the particle diameter and the filtration efficiency to the particulate matter are direct ratio in these two kinds of techniques, and the particle diameter is bigger, and the filter effect is better. 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. Therefore, the prior art has problems and disadvantages:

firstly, during air purification, the particle size of particulate pollutants is too small to be easily captured;

second, physical interception (HEPA) technology increases the filtration level of the filter in order to improve the capture efficiency of small-particle-size pollutants, increasing wind resistance and cost;

thirdly, 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 the small-particle-size pollutants.

Therefore, it is necessary to provide an air cleaner capable of condensing and treating particulate matters in air before filtering, increasing the particle size of pollutants, and reducing the number of pollutants.
