Three-unit UV ambient air purification device

Abstract

The invention discloses a three-unit UV high-performance ambient air purification device, and belongs to the technical field of high-performance novel ambient air purification. The device comprises amachine body, a display panel, an exhaust inlet, an exhaust outlet, a humidity adjusting device, a fixed handle, a power supply, a high-power mute variable-speed turbofan, a UVA ultraviolet lamp bank,a photocatalytic oxidation unit reactor, an electrostatic dust collection device, a primary filter screen, an activated carbon filter screen and a composite Ag<+> / TiO2 sterilization-disinfection filter screen. The three-unit UV high-performance ambient air purification device is characterized in that a machine body shell and part of parts are made of metal materials; air is sucked in from three sides and is exhausted from the top; particulate matters in the air can be subjected to dust removal and purification, and indoor dust is reduced; and volatile organic compounds are degraded through photocatalysis, the effects of sterilization, disinfection and epidemic prevention are achieved, planktonic bacteria and viruses in air can be efficiently killed, cross infection of epidemic situationsis controlled, indoor air is purified, and public health and safety are guaranteed.

Description

technical field [0001] The invention relates to a three-unit UV ambient air purification device, which belongs to the technical field of high-performance novel ambient air purification. Background technique [0002] Indoor environmental pollution is the third largest air pollution problem in the world after bituminous coal pollution and photochemical pollution. my country is one of the countries with serious indoor air quality problems. The main reasons for indoor air pollution are as follows: First, the decoration materials used contain a large amount of toxic organic substances such as formaldehyde, benzene, ammonia and polycyclic aromatic hydrocarbons, and these substances volatilize into the air. Excessive inhalation by the human body will endanger human health; the second is the biological pollution caused by microorganisms, including bacteria, fungi and viruses, which can cause various diseases such as respiratory tract and asthma; the third is that the ventilation effe...

Problems solved by technology

[0004] Most of the existing environmental purification devices in the market are activated carbon adsorption and high-efficiency filter (HEPA) adsorption and filtration. Activated carbon can absorb odors in the air in a short time and purify the air, but it cannot effectively decompose harmful pollutants and easily cause secondary pollution. , and need to be replaced regularly; the HEPA filter can reach 99.9% filtration efficiency for particles above 0.3 microns, which is a safe and reliable dust removal technology, but it is easy to damage, cannot be washed with water, must be replaced regularly to continue to use and expensive to maintain; The density of the HEPA filter is high, and a powerful exhaust and suction fan is necessary to drive the air to flow through it, which consumes more power

These existing purification devices can only purify indoor air in a short period of time, and do not have the function of disinfection and sterilization. Regular replacement of components is required, and subsequent maintenance costs are high
