Embodiment 1

[0012] Such as figure 1 As shown, the present invention comprises: air purification chamber 1, air inlet 2, heater 3, negative ion generator 4, particle catcher 5, air outlet 6, wherein air inlet 2 is positioned at air purification chamber 1 top, heater 3 is placed in the upper part of the clean room 1, the negative ion generator 4 is placed in the lower part of the air clean room 1, the particle trap 5 is located in the lower part of the negative ion generator 4, and the air outlet 6 is located in the bottom of the air clean room 1. The ratio of the power (W) of the heater to the aspect ratio (cm / cm) of the air cleaning chamber is 8. The present invention utilizes the thermophoretic effect that fine particles in the airflow will move and gather toward the side with lower temperature under the condition of temperature gradient, and make the PM2. The catcher 5 collects, so as to achieve the effect of purifying the air, and the absorption rate of PM2.5 particles can reach 30%. ...

Embodiment 2

[0014] Also used as figure 1 With the shown structure, when the ratio of the heater power (W) to the aspect ratio (cm / cm) of the air purification chamber is 35, the absorption rate of PM2.5 particles can reach 50%.

Embodiment 3

[0016] Also used as figure 1 With the shown structure, when the ratio of the heater power (W) to the aspect ratio (cm / cm) of the air purification chamber is 25, the absorption rate of PM2.5 particles can reach 41%.

Abstract

The invention discloses a novel air purifier based on a thermophoresis effect, which comprises an air purifying chamber, an air inlet, a heater, a negative ion generator, a grain catcher and an air outlet, wherein the air inlet is located on the upper part of the air purifying chamber; the heater is arranged on the upper part in the air purifying chamber; the negative ion generator is arranged on the lower part in the air purifying chamber; the grain catcher is located on the lower part of the negative ion generator; the air outlet is located at the bottom of the air purifying chamber; the grain catcher is a superfine glass fiber; and the aperture is 0.1-0.3 microns. Under the thermophoresis effect, PM2.5 grains are electrified and accelerated to fall under the action of the negative ion generator and are collected by the grain catcher, so that the absorbing rate of the PM2.5 grains reaches 30-50%.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to an air purifier which consumes less electricity and removes dust efficiently. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. There are thousands of types of air purifiers on the market, but none of them can solve the problem of absorbing fine particles, especially PM2.5. Contents of the invention [0003] The purpose of the present invention is to provide an air purifier capable of absorbing PM2.5 fine particles. [0004] In order to achieve the above object, the present ...
