Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:
[0020] like figure 1 A new type of pulse photocatalysis-post-metal oxide catalytic plasma reactor shown includes a cylinder 4, a head 1, an air inlet 9 and an air outlet 2, and a cylinder 4 is closely attached to the inner wall of the cylinder 4. A layer of metal mesh 5, the metal mesh 5 is a stainless steel metal mesh. On the central axis of the cylinder body 4, a metal tube 10, preferably a stainless steel tube, is installed on the central axis, and one end is grounded; a corundum tube 8 is tightly sleeved outside the middle section of the metal tube 10. 8 is loaded with a photocatalyst layer 7, and the photocatalyst is loaded TiO2. Photocatalyst TiO 2 It has the advantages of anti-oxidation and light corrosion, stable and non-toxic, high catalytic activity, and low price. In order to increase the specific surface area and ...

The invention relates to a novel pulse photocatalysis-post metallic oxide catalysis plasma reactor, comprising a bowl (4), an end socket (1), an air inlet (9) and an air outlet (2); a metal tube (10) penetrates the bowl (4); an alundum tube (8), a photocatalyzer layer (7) and a tungsten filament (6) are arranged orderly outside the metal tube (10); a metal net (5) is arranged on the inwall of the bowl (4); a post-loaded metallic oxide ball-type catalyzator (3) is arranged on an end closed to the air outlet (2) inside the bowl (4). The novel pulse photocatalysis-post metallic oxide catalysis plasma reactor is capable of effectively removing an indoor volatile organic chemical substance VOCs or an order component of over 90 percent in a sewage plant, thereby having the advantages of good purification effect and high energy utilization ratio.
Description
technical field [0001] The invention relates to an ion plasma reactor, in particular to a novel pulse photocatalysis-post-metal oxide catalytic plasma reactor. Background technique [0002] Indoor air pollutants have the characteristics of low concentration and great harm. While causing widespread concern, it also promotes the process of indoor air purification technology. At present, the purification methods that are still widely used mainly include ventilation, filtration and adsorption. However, in terms of the size of pollutant particles, treatment efficiency, treatment of toxic and harmful gases, such as NOx, SOx, VOCs, etc., and the killing of bacteria, traditional methods have been unable to meet the needs of modern indoor air pollution control, especially for When treating low-concentration air pollutants, the cost is high and the energy consumption is high. [0003] In recent years, new methods such as electrostatic collection, ozone oxidation and gas-phase filtra...
