Optical-thermal coupling air purifier having honeycomb arrangement

[0015] Example 1:

[0016] Please refer to Figure 1 and Figure 2. The honeycomb carrier material is metal aluminum, and aluminum is made into a honeycomb with hexagonal holes. The surface is treated according to the method indicated in our previous patent application 03102878, and coated with the photocatalyst specified in our previous patent application 98115808. The coating method is in accordance with the method provided in our previous application patent 03102878. One end of the purifier is the front cover (7), the end of the front cover (7) is the air inlet (1), the center of the front cover (7) is installed with a fan (2) and a flow regulating plate (8) , The other end of the front cover is connected to the housing; the housing (3) is equipped with a honeycomb photocatalytic reactor (9), a compact heating device (5) is installed between the honeycomb walls, and the honeycomb center is installed Ultraviolet lamp (4); the other end of the casing (3) is connected with a rear cover (6), and the other end of the rear cover (6) is an air outlet (10). In this embodiment, the electric heating device is made of a flat electric heating tape, and the heating power is 400W. The photo-thermal catalytic air purification experiment of the purifier was completed in a fully sealed 30 cubic meter evaluation room, using benzene pollutants as model gases, and the degradation process is shown in Figure 3.

[0017] Example 2:

[0018] Please refer to Figure 1. The honeycomb-shaped carrier material is stainless steel, and the electric heating device uses thin electric heating wires, and the heating power is 500W. The organic pollutants selected formaldehyde and ethanolamine. The stainless steel sheet is made into a honeycomb with pentagonal holes. One end of the purifier is the front cover (7), the end of the front cover (7) is the air inlet (1), the center of the front cover (7) is installed with a fan (2) and a flow regulating plate (8) , The other end of the front cover is connected to the housing; the housing (3) is equipped with a honeycomb photocatalytic reactor (9), a compact heating device (5) is installed between the honeycomb walls, and the honeycomb center is installed Ultraviolet lamp (4); the other end of the casing (3) is connected with a rear cover (6), and the other end of the rear cover (6) is an air outlet (10). The degradation process is shown in Figure 4.

[0019] Example 3:

[0020] Please refer to Figure 1. The honeycomb-shaped carrier material is a non-woven fabric, and the catalyst is directly heated by an ultraviolet lamp that generates heat during operation. Inorganic pollutants select different initial concentrations of SO 2 gas. A honeycomb purifier with round holes is made of aluminum sheet. One end of the purifier is the front cover (7), the end of the front cover (7) is the air inlet (1), and the center of the front cover (7) A fan (2) and a flow regulating plate (8) are installed, and the other end of the front cover is connected to the casing; a honeycomb photocatalytic reactor (9) is installed in the casing (3), and the honeycomb walls are installed There is a compact heating device (5), an ultraviolet lamp (4) is installed in the center of the honeycomb; the other end of the casing (3) is connected with a rear cover (6), and the other end of the rear cover (6) is an air outlet (10) ). The degradation process is shown in Figure 5.
