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, b

Embodiment 1

[0075] Such as Figure 1-Figure 4 As shown, a three-unit UV ambient air purification device is provided with a cube-shaped body 7, the front panel of the body 7 is provided with a horizontal suction port 32 near the bottom, the front panel is provided with a display panel 2 near the top, and the top cover of the body 7 1 is provided with an air inlet 4, the air inlet 4 is close to the rear panel of the body 7, vertical air suction ports 31 are provided on both sides of the body 7, and the vertical air suction port 31 is located close to the front panel; The device 5 is close to the front panel of the body 7, the humidity adjustment device 5 is provided with a primary filter 15 and an active carbon filter 14 in parallel, the primary filter 15 is close to the front panel of the body 7, and a turbo blower 18 is arranged below the air outlet 4, and a turbo blower 18 Located in the middle of the rear panel of the body 7, between the turbo blower 18 and the activated carbon filter 1...

Embodiment 2

[0077] When the device is started, polluted air passes through the turned-on high-power silent variable-speed turbo fan 18, and is sucked into the metal body 7 by three air suction ports at the same time, first passes through the electrostatic dust removal device installed around the air suction port, and then passes through the primary filter 15 to filter out flocculent particles. After dust, allergens, etc., enter the activated carbon filter 14 to absorb and filter again, enter the UV photocatalytic oxidation system composed of three sets of photocatalytic oxidation unit reactors 11 and two sets of UVA ultraviolet lamp sets 12, polluted air and foam ceramics The titanium dioxide film supported by the solid photocatalyst is contacted, and after the photocatalysis of the UVA ultraviolet lamp group 12, the titanium dioxide film decomposes the harmful substances in the polluted air, and then enters the composite Ag + / TiO 2 Sterilization-disinfection filter screen 13 is steriliz...

Embodiment 3

[0080] Composite Ag + / TiO 2 Catalyst and Composite Ag + / TiO 2 The preparation method of sterilization-disinfection filter screen:

[0081] Using nano-Ag with a content of 1.5wt%-2wt% + Inorganic sol solution and TiO 2 Under the condition of 120℃, the nano-Ag + Inorganic sol solution and TiO 2 The mass ratio is 1-2:1-2:6-8, and the neutral composite Ag is prepared by hydrothermal synthesis + / TiO 2 catalyst, will compound the Ag + / TiO 2 The catalyst is evenly sprayed on the folded sawtooth filter (HEPA filter) by using a high-pressure spray gun to form a composite Ag + / TiO 2 Bacteria-sterilizing filter. Composite Ag + / TiO 2 The catalyst forms a thin film with a film thickness of 200-300nm on the surface of the filter, compounded with Ag + / TiO 2 The amount of catalyst used is between 18-20g, so that it has the effect of adsorption and decomposition of aerosol virus, sterilization and epidemic prevention, safety and long-term effect, and broad-spectrum disin...

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...
