Problems solved by technology
[0004] At present, for newly renovated houses, users need to regularly ventilate the new house to reduce the formaldehyde content in the air of the new house. In the prior art, photocatalysts have been used to remove formaldehyde indoors, but in the actual use process, the applied photocatalyst layer It is easy to fall off during use, which reduces the service life of the photocatalyst layer

Embodiment 1
[0045] see Figure 1-6 , a formaldehyde removal device based on point-convex flushing photocatalyst, including a glass wall tile 1, and a built-in cavity 2 is excavated inside the glass wall tile 1, and the built-in cavity 2 is filled with a gas-solid mixed medium 3, and the right side of the built-in cavity 2 The inner wall is excavated with a plurality of uniformly distributed photoreaction grooves 4, the inner wall of the photoreaction groove 4 is fixedly connected with an elastic disc film 5, and the right end of the elastic disc film 5 is fixedly connected with a convex residual ball 6 and an outer convex residual ball 6. The photocatalyst layer 7 and the end of the convex residual ball 6 away from the elastic disc film 5 are threadedly connected with a connecting cylinder 8, and the inside of the glass wall tile 1 is excavated with a plurality of evenly distributed annular storage tanks 9 located on the upper side of the photoreaction tank 4, The annular storage tank 9 i...

The invention discloses a formaldehyde removal device based on a point-convex washing type photocatalyst and belongs to the technical field of air purification. In the technical scheme, light irradiates on glass wall bricks, so that nitrogen dioxide in a gas-solid mixed medium can be promoted to be decomposed into nitric oxide and oxygen, and the gas-solid mixed medium is expanded. Therefore, theelastic wafer film is supported to be in a point convex shape, and the purification effect of the elastic wafer film on indoor air is improved; meanwhile, the possibility that the photocatalyst layeris scraped off in the actual use process is reduced, when the elastic wafer film is supported, part of the traction fiber rope can be pulled out of the annular storage groove, and a small amount of ammonium nitrate powder is discharged of the annular storage groove; in addtion, the ammonium nitrate powder has high deliquescence performance, the surface of the traction fiber rope can be forced to be wetted, and the surface of the photocatalyst layer can be cleaned along with accumulation of an aqueous solution on the traction fiber rope and dripping of the aqueous solution to the surface of thephotocatalyst layer, so that the possibility that dust is attached to the surface of the photocatalyst layer to reduce photocatalysis is reduced.
Description
technical field [0001] The invention relates to the technical field of air purification, more specifically, to a dot-convex flushing photocatalyst formaldehyde removal device. Background technique [0002] Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust and haze removal, harmful decoration residues and peculiar smells, so as to improve living and office conditions and improve physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gases, molds, particulate matter, decoration residues, second-hand smoke, etc., electrical devices that have a certain ability to remove solid pollutants and gaseous pollutants in indoor air; can remove two or two An air purifier that removes more than one air pollutant is called a multifunctional room air purifier. Pollutants mainly refer to bacteria, viruses, solid pollutants (such as dust, pollen, ba...
