Description

Composite structure air cleaner

This work belongs to the field of air cleaning equipment, especially about an air cleaning machine with a composite structure, so as to use the hydrogen and oxygen free radicals produced by the photocatalyst, high-concentration ozone and negative ions to achieve the functions of air purification, disinfection and sterilization, and a part of it The high-concentration ozone will be re-inhaled into the air inlet to increase the hydrogen and oxygen free radical generation rate of the photocatalyst generating device, and the negative ions can combine with suspended particles (PM2.5) in the air to achieve the effect of air purification by settling and dusting By.

According to, with the vigorous development of industry, commerce and transportation, a large number of suspended particles exist in the environment when the exhaust gas is discharged, which is one of the main indicators of air pollution. Due to the small size and light weight of the suspended particles, they can stay in the atmosphere for a long time. And as people breathe into the body, accumulating in the trachea or lungs will affect health.

At present, in order to remove suspended particles in the indoor air, air cleaners are often used. The purification process is to use the air cleaner to drive the circulation of indoor air to achieve the purification effect. Inhale for preliminary filtration, and then use the internal photocatalyst generating device and ultraviolet light to improve the disinfection and sterilization steps. However, in order to improve the effect of filtering suspended particles, these filters are designed with very small pore diameters, so the suction must be increased The suction power of the fan can effectively inhale and filter the air, and then carry out further disinfection and sterilization. As the suction power increases, the flow rate of the air entering the air purifier will also increase, reducing the time it stays inside and leading to disinfection The sterilization time is shortened and the effect is not obvious. However, with the type of resistant strains Children or the elderly with low immunity often suffer from invisible and latent infection threats when they are active in public places. These drug-resistant strains are not suitable for physical damage (for example: physical disinfection methods such as ultraviolet rays, high pressure, and high temperature) The tolerance of the drug-resistant bacteria is still low, so in many public places, ultraviolet sterilizing devices will be used to suppress the infection of these drug-resistant strains. Certain damage, so the time for each ultraviolet sterilization ranges from tens of seconds to several minutes, and the effect of disinfection and sterilization cannot be effectively improved in places that have not been irradiated, which is what the author of this case and related manufacturers engaged in this industry Those who are eager to study the direction of improvement.
