Problems solved by technology

With the help of secondary photocatalyst products compounded on the carrier, the following defects still exist in the catalytic degradation: ①Binder coating, fine dust particles in polluted gas, bacteria, viruses, or degraded molecular groups intercept and produce surface electron hole poisoning failure ;②In the normal use state, the cavity needs to be in close contact with the bacteria and viruses that are sterilized and degraded, The catalytic activity and effect of photocatalysts are relatively weak compared with chemical catalysts, and the efficiency needs to be considered

Embodiment 1

[0039] Embodiment 1, a processing method of a custom-made antibacterial and antiviral photocatalyst filter element, based on the composite manufacturing process of glass long fiber mat and photocatalyst, including the preparation of photocatalyst suspension and the composite positioning of nano-scale crystal grains on the glass long fiber, Specifically include the following process steps:

[0040] . Material preparation: select the glass fiber mat made of continuous raw silk, wash and dry it for later use; prepare supporting photocatalyst dispersion mother liquor: mix 1000g of titanium oxysulfate with an average particle size of 25nm in 50000ml of water, add 11000ml of 2.5% Ammonia water, settling for 30min, remove the supernatant, centrifuge at 8000r / min, mix the centrifuged solid matter with 9000ml of water, ultrasonic, and stir evenly; then add 1000ml of acrylate, ultrasonically disperse for 30min.

[0041] . Forming and support of the basic filter unit: process and p...

Embodiment 2

[0046] Embodiment 2, the processing method of the photocatalyst filter element is basically the same as Embodiment 1, the difference is that the cylindrical frame 2 in the communication positioning mechanism is thinner and longer than Embodiment 1, and the upper and lower cover structures are changed to form parallel filtering channels. In this embodiment, the upper cover 6 includes an air outlet 6-1 arranged in the center and an upper sealing pressure plate 6-2 and an upper sealing pressure plate 6-2 which are arranged in the lower part and match the air outlet ports of the filter unit housing 1. Attach the elastic gasket. The lower cover 7 includes an air inlet 7-1 with a ring-shaped cross-section arranged in the center and a lower sealing plate that is arranged on the upper part of the lower cover 7 and matches each air intake port of the filter unit housing 1. The lower sealing plate is attached The lower elastic gasket is evenly distributed between the air inlet 7-1 and t...

Embodiment 3

[0047] Embodiment 3, an antibacterial and anti-virus filter device, the filter element of which is manufactured by the process of Embodiment 1. Blower 12 is installed in the bottom of lower cover 7 ', and base 8 and loam cake 9 with ventilation structure are installed at both ends again, and gac coarse filter screen 10 and HEPA filter screen 11 are installed in base 8. Loam cake 9 and loam cake 6 ' integral installation. The filter device has a good effect of killing and degrading bacteria and viruses, and the sterilization rate of one pass can reach more than 95%.

Abstract

The invention relates to a processing method and a product of a customized antibacterial and antiviral photocatalyst filter core, and belongs to the application field of a photocatalysis technology. The method is characterized in that photocatalyst dispersion liquid is uniformly loaded on inorganic fiber felt manufactured by continuous protofilaments; then, glass fiber felt is cut into a shape matched with a steel mesh model sleeve and is loaded in the steel mesh model sleeve to be roasted at 450 to 650 DEG C; organic matters are decomposed; photocatalysts are sintered on the inorganic fiber to form an inorganic fiber based compound filter material; then, the compound filter material is transferred into a non-light tight filtering unit casing and is assembled into a customized filter coreof a filter together with a communicated positioning mechanism. The manufacturing method is suitable for industrial production, can be used in various kinds of filtering and purification equipment oroccasions.

Description

technical field [0001] The invention belongs to the application field of photocatalysis technology, and relates to a photocatalyst antibacterial purification device using glass fiber as a carrier, in particular to a custom-made photocatalyst air ultra-purification unit and a processing method thereof. Background technique [0002] The mechanism of action of the photocatalyst is to excite the nano-scale titanium dioxide material with light, and generate photogenerated holes and transition electron clouds on its surface. The hydroxyl radicals generated on the surface layer of the nano-scale structure mold supported by the photoelectric effect have a strong oxidation ability, which can effectively Degrades organic pollutants or kills bacteria or viruses. Therefore, since the characteristics of photocatalyst materials were discovered and deeply understood, they have been sought after and researched by people. In particular, this functional material with environmental protection...
