Haze particle eliminating device

Abstract

The invention provides a haze particle eliminating device. The haze particle eliminating device comprises a fan, a first absorption region and a second absorption region, wherein the first absorption region comprises a first substrate impregnated with a first impregnant, the second absorption region comprises a second substrate impregnated with a second impregnant, the first substrate and the second substrate are respectively made from a porous air-permeable material, the first impregnant is Vaseline, or an organic weakly-polar sticky substance or an organic non-polar sticky substance, and the second impregnant comprises an aqueous solution of a sticky alkaline substance; the first absorption region and the second absorption region are mutually overlapped, interchangeable in position and arranged in an air-permeable filter bag, and the fan sucks air into the air-permeable filter bag. The haze particle eliminating device provided by the inveniton has a good haze eliminating effect and is low in cost, adsorbed haze particles are hardly desorbed, and no ozone pollution is generated.

Description

【Technical field】 [0001] The invention relates to a device for eliminating haze particles. 【Background technique】 [0002] Smog has frequently erupted in the air of some industrial cities in my country on a large scale. The aerosols that constitute smog are very complex. There are two main ways to form aerosols (particulate matter): primary emission and secondary generation. Primary emission refers to the emission of particulate matter directly into the atmosphere by pollution sources. Secondary generation refers to the conversion of gaseous compounds emitted by pollution sources into particulate matter through atmospheric chemical reactions in the atmosphere, such as the conversion of sulfur dioxide gas into sulfate particulate matter. Compared with the primary emission, the particle size of the secondary generation is usually smaller and occupies a large proportion. PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, al...

Problems solved by technology

[0006] This method does not require high-power electrodes, and the air handling capacity can be increased correspondingly. However, the side effects of this machine are also obvious:

[0007] (1) Static electricity is easy to generate ozone, which is also a pollutant and a serious carcinogen (copiers, etc. are also machines that generate ozone). Independent ventilation is required to remove ozone pollution (discharged outdoors, and cannot participate in the air circulation of central air conditioning);

[0008] (2) Floating particles with static electricity are easy to adsorb to other places (such as walls and other electrical appliances and other objects with opposite charges), and long-term use will cause problems for cleaning;

However, the volume of the device is quite large, often tens to thousands of cubic meters, and it must be used in a large space, and liquid foam often overflows with the gas during operation.
