Composite air sterilization purifying installation using ozone and optical catalytic decomposition device

Abstract

A composite air sterilization and purification device that uses ozone and a photocatalytic decomposer, the composite air sterilization and purification device of the present invention is an air sterilization and purification device that combines ozone and photocatalysts, that is, the pollutant sensing sensor that is located at the inlet or outlet The received electrical signal is sent to the variable output stabilizer (Dimming Balast) system to make the output intensity of the ozone generating lamp vary within the range of 100-5%, thereby adjusting the amount of ozone generated. When the amount of pollutants is large, increase the amount of ozone generation, and reduce the amount of ozone generation when the amount is small. When the amount of pollutants exceeds the decomposition capacity of the photocatalytic decomposer, ozone is used to remove pollutants. According to the present invention, by using the carrier in the form of a spring in the photocatalytic decomposer, while reducing the pressure loss of the device, it can also provide sufficient contact area for ozone and ultraviolet rays, and easily fill the carrier.

Description

technical field [0001] The invention relates to a composite air sterilization and purification device which can sterilize and decompose suspended bacteria and pollutants (VOC, Volatile Organic Compound) in the air by using the oxidation reaction of ozone and photocatalyst. Specifically, it involves the use of combining a photocatalyst decomposer and an ozone generator according to the amount of pollutants, and adjusting the amount of ozone generated by a dimming stabilizer system that adjusts the output intensity of an ozone lamp. A composite air sterilization and purification device of ozone and photocatalytic decomposer. Background technique [0002] The recent energy saving policy is developed along the direction of separating the indoor air from the outside. The pollutants discharged from various interior decorations further deteriorate the quality of the indoor air, which will cause serious harm to the human body such as respiratory diseases. influences.

Problems solved by technology

In bead form, the pressure loss is very large because the air has to pass only in the gap between the beads, and a blower with high static pressure is required, so the power consumption and noise are increased

In addition, since the beads themselves block ultraviolet rays from reaching the carrier behind, the ultraviolet rays cannot be irradiated smoothly to places far away from the lamp, so the reactivity is reduced instead.

[0018] Considering the pressure loss, the device designed so that the air can flow parallel to the lamp by arranging tubes or plates, although the pressure loss is small, but the decomposition reaction activity is low due to the small reaction surface area

When filling the carrier, the smaller the gap, the greater the pressure loss of the air passing through, and the ultraviolet rays cannot irradiate the inside of the carrier, so the efficiency of the decomposition reaction will be reduced instead.
