Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as Figure 1-3 As shown, the air enters from the gas inlet 1, passes through the inlet area and then enters the adsorption device area. The air in the area of ​​the adsorption device must first be purified and filtered by the small conical sawtooth 2. The tooth height of this sawtooth structure is small and the tooth spacing is relatively close. The purpose is to reduce the impact of this structure on the incoming flow. After the first purification, the gas enters the purification of the large conical sawtooth 3. It is worth noting that the sawtooth structure design is connected to the heating device 4 on the upper wall, and the activated carbon 9 is placed on the lower wall 5. The thermophoretic effect and the chemical properties of the activated carbon will produce a better filtering effect for small particles. Finally, the air enters the fan area. There is ...

Abstract

The invention discloses an air small particle adsorption device based on thermophoretic effect. The present invention is composed of three parts: the air inlet area, the adsorption device area and the fan area. Design, the upper wall of the adsorption device is connected to the heating device, and the lower wall is placed with an activated carbon device. There is a stable air flow area in the last fan area, and then there is a full-section filter partition in the middle, and the exhaust fan adopts a low-power fan to ensure the slow passage of the particle air flow. The invention makes the purification process simpler, more efficient and produces no new by-products harmful to human health.

Description

technical field [0001] The invention relates to an adsorption device for small particles in the air, which belongs to the field of air purification. Background technique [0002] In recent years, particulate pollutants in the air have increased day by day. Particles such as PM2.5 and PM10 in the air seriously endanger people's health. Traditional air purifiers are no longer able to isolate small particle pollutants in the air. Therefore, electrostatic (ionization) purification technology came into being. However, the disadvantages of electrostatic (ionization) purification technology are also obvious. For example, 1. It releases high-voltage electricity to the air to produce ozone that is irritating to the lungs. 2. The particles that are not captured will become charged particles that are more harmful to the human body and will be released into the room. 3. The captured particles will return to the air. 4. With use, the purification efficiency decreases. 5. Frequent ...
