Currently, many companies use activated carbon adsorption, biodegradation, or plant-derived deodorizing liquids to remove odor pollution from industrial waste gas. However, all of these methods have drawbacks such as high cost, low purification rate, and the tendency to cause secondary environmental pollution. As people’s awareness of environmental protection increases, their requirements for environmental quality are also getting higher and higher. Focusing only on the prevention and control of atmospheric pollution from dust, SO2, and NOx can no longer meet people’s requirements for the atmosphere, and people are more sensitive to the pollution caused by odor. In order to extend the service life of the fan, the fan is installed after the scrubber. There is no need to worry about gas pollution. The exhaust gas purification tower has adsorption purification, good temperature adaptability, low operating cost, and one-time addition of fillers, which can meet the requirements of long-term operation. It is easy to operate, manage, and maintain, and no secondary pollution is generated during operation.
Functional features of photocatalytic purifier:
It has a high one-time purification rate and can purify multiple pollutants at the same time.
The performance adopts triple automatic protection of switch, power supply and circuit.
The equipment is small in size, compact in structure and has mature technology.
Small equipment investment and low operating costs.
Stable, easy to maintain and long service life.
Purification, no secondary pollution.
Working principle of photocatalytic purifier:
Use UV light beams to crack the molecular bonds in the malodorous gas, destroy the nucleic acid (DNA), and then use ozone to carry out oxidation reaction to achieve the purpose of deodorization and killing. Our company’s photocatalytic purifier products use high ozone UV ultraviolet light beams to irradiate the malodorous gas.
Photocatalytic purifiers use high-ozone UV light to decompose oxygen and water molecules in the air, producing free oxygen (active oxygen species) and OH radicals. Due to the imbalance between the free oxygen and the positive and negative electrons it carries, it combines with oxygen molecules to produce ozone. UV + O2 — O_ + O* (active oxygen species) + O2 — O3 (ozone). Ozone is known to have a strong oxidizing effect on substances and is effective against industrial waste gases and other irritating odors.
Although the internal structure of the photocatalytic purifier is not particularly complicated, it still requires personnel maintenance. First, the pipes must be cut and a rope must be fixed on the cut surface to clean the photocatalytic purifier equipment from top to bottom. This method seems simple, but the cost and risk are relatively high. Cleaning is also good. Since the purification cycle of the photocatalytic purifier equipment is relatively long, as long as it does not exceed one year, it is still relatively reliable.
