Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic dust removal and relates to an air supply unit and an air purification device without a fan. Background Art

[0002] As people's environmental awareness is increasing, the recognition and purification demand for pollutants in the air (including but not limited to oil smoke, dust, VOCs) is also increasing. Therefore, more and better purification technologies are gradually being installed and used in restaurant kitchens, factories, and home environments. Among these purification technologies, electrostatic dust removal and adsorption technology has a very common application. The principle of electrostatic dust removal and adsorption technology is that the gas is ionized when passing through the electrostatic field. After the particles in the gas combine with the charged ions, they tend to move to the electrode with the opposite polarity to the charged ions and deposit. It can be seen that the particle removal rate is related to the charging efficiency of the particles. The core electrostatic field is mostly composed of an adsorption plate and a cathode wire (discharge electrode) arranged in the adsorption plate. Therefore, the technology of the adsorption plate and the discharge electrode has become the key to improving the particle removal rate.

[0003] The existing technology still has the problem that the discharge electrode and the adsorption electrode are made of metal materials, which not only has complex manufacturing process, difficult to control assembly accuracy, and high production cost, but also has technical problems such as poor particle removal rate and purification effect after the discharge electrode and the adsorption electrode are combined.

[0004] In addition, most electrostatic dust removal air purification devices use traditional fans to deliver or extract air to achieve the purpose of air purification. Traditional fans have a single function in electrostatic dust removal air purification devices, which increases energy consumption. At the same time, the noise of traditional fans increases with the increase of wind speed and the wind speed is uneven, which not only affects the user experience but also makes the local working intensity of the electrostatic dust removal air purification device higher.
