Photocatalytic exhaust gas treatment equipment

1Mechanism of photocatalytic equipment】

The mechanism of action of photocatalytic exhaust gas treatment equipment is to use high-energy high ozone UV ultraviolet beam (hereinafter referred to as UV ultraviolet beam) to crack the molecular structure of exhaust gas, causing the molecular chains of organic polymer compounds to break and transform into low molecular weight inorganic compounds such as CO2 and H2O.

The waste gas molecules that can be cracked by photocatalytic equipment include ammonia, trimethylamine, hydrogen sulfide, methylthiohydride, methyl mercaptan, methyl sulfide, butyl acetate, ethyl acetate, dimethyl disulfide, carbon disulfide, styrene, sulfides, VOCs, benzene, toluene, xylene, etc.

UV beams can break down oxygen molecules in the air to generate free oxygen, also known as reactive oxygen species. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to produce ozone. The reaction equation is as follows:

(Photocatalytic equipment)

UV+O2 → O -+O * (reactive oxygen species) O+O2 → O3 (ozone)

Ozone has an oxidizing effect on organic matter and a cleaning effect on industrial waste gas. After the exhaust gas is introduced into the reaction chamber through the exhaust equipment, the UV ultraviolet beam and ozone decompose and oxidize the exhaust gas, causing it to degrade into low molecular compounds, which are then discharged outside through the exhaust duct.

In addition, UV beams can also damageBacterial DNA sequence to achieveThe purpose of sterilization and disinfection. From the perspective of waste gas treatment, the use of pulse corona adsorption technology combined with C-band ultraviolet radiation corona device can destroy the molecular structure of waste gas molecules such as hydrogen sulfide, ammonia, benzene, toluene, xylene, formaldehyde, ethyl acetate, ethane, acetone, urea, resin, etc., transforming organic substances into inorganic substances.

【3、 Characteristics of photocatalytic treatment technology for photocatalytic oxidation】

(1) No toxic side effects. The photocatalytic equipment surpasses traditional treatment devices and can continuously sterilize and remove dust in a human presence, with no toxic side effects on the human body. It can intercept and kill various types of bacteria in the air with a broad-spectrum effect. Tests have shown that the killing rate of Bacillus subtilis, black mutant spores, and natural bacteria is over 99.9%, effectively removing inhalable particles and achieving a cleanliness level of 10000 to 100000.

(2) Eliminating harmful gas odors, primary electrons are accelerated in an electric field and collide with oxygen molecules in the air. When the energy exceeds the ionization potential of oxygen molecules, they rapidly ionize. The oxygen molecules that lose electrons become positive polarity oxygen ions (O2+), while the released electrons combine with another neutral oxygen molecule to form negative polarity oxygen ions (O2-). The result is the two-stage differentiation of oxygen ions and the adsorption of neutral oxygen molecules to form ion groups such as O2+, O2-, O2, etc., which have oxidizing properties and can quickly oxidize and decompose harmful components in polluted air into harmless products and water; O2+e（3.6eV）→•O+O H2O+e（5.09eV）→•OH+HO+•OH→•OH2

(3) Research has shown that the oxidation potential of reactive free radicals • OH (2.8eV) is 35% higher than that of oxidizing ozone (2.07eV). The reaction rate between OH radicals and organic compounds is several orders of magnitude higher. Moreover, the reaction of • OH radicals to oxidize pollutants is non selective and can trigger a chain reaction, directly oxidizing most harmful substances in polluted air into carbon dioxide, water, or minerals.
