The invention provides a filter element for filtering gas, a filter element skeleton, the outer wall of the filter element skeleton is provided with a chemical fiber filter layer, a glass fiber filter layer and a polyester fiber filter layer sequentially along the radial direction, the chemical fiber filter layer, A layer of titanium dioxide particles and photosensitizer particles are attached to the outer surfaces of the glass fiber filter layer and the polyester fiber filter layer. The chemical fiber filter layer and the polyester fiber filter layer are both wavy. Rare earth fluorescent powder, the inner and outer circumferences of the glass fiber filter layer are partially embedded with convex parts formed by transparent capsules, and the inside of the transparent capsule is filled with rare earth fluorescent powder. The present invention discloses a filter element for filtering gas. By implanting a light source body inside the filter element, it is equipped with photocatalytic decomposition reaction from the inside, and achieves the effect of self-purification under external reaction conditions, thereby improving the efficiency of the filter element. efficiency and service life.
Description
technical field [0001] The invention relates to the field of environmental protection and purification and the field of filter materials, and more specifically relates to a filter element for filtering gas and a purification method. Background technique [0002] During the filtering process, the surface of the gas filter element will absorb a large amount of particulate impurities. As the impurities continue to increase, the filter pores on the surface of the gas filter element will be blocked, and filter cakes, dust bridging, etc. will be formed on the surface of the gas filter element. Therefore, it is necessary to The impurities accumulated on the surface of the gas filter element are removed to realize the regeneration of the filtration function of the gas filter element. There are generally mechanical methods to remove impurities on the surface of the gas filter element, such as brushes or mechanical oscillation methods, but the equipment structure of this mechanical me...
