ONE. Equipment overview

       The photocatalytic purification device (LGO) generates photons of different energies through a special ultraviolet light source, and uses the strong absorption of photons by the odorous waste gas substances to dissociate and excite the odorous waste gas molecules under the bombardment of a large number of energy-carrying electrons, and make them free. The pollutant molecules in the state are combined with ozone oxidation to form small molecules of harmless or low-harm compounds, such as CO2, H2O, etc.

TWO. Scope of application

       Deodorization and purification of odorous gases in refineries, rubber plants, chemical plants, pharmaceutical plants, sewage treatment plants, garbage transfer stations, etc.

THREE. Working principle
       1. This product uses a special high-energy ozone UV ultraviolet beam to irradiate malodorous gases, cracking malodorous gases, such as: ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and benzene Ethylene, sulfide H2S, VOCs, molecular bonds of benzene, toluene, and xylene.
       2. Using high-energy ozone UV ultraviolet beam to decompose oxygen molecules in the air to generate free oxygen, that is, active oxygen. Because the positive and negative electrons carried by free oxygen are unbalanced, they need to be combined with oxygen molecules to generate ozone. Ozone has a strong oxidizing effect on organic matter, and has a strong scavenging effect on malodorous gases and other irritating odors.
UV+O2→O-+O* (active oxygen) O+O2→O3 (ozone)
       3. After the malodorous gas is input into the purification equipment by the exhaust equipment, the purification equipment uses high-energy UV ultraviolet beam and ozone to carry out a synergistic decomposition and oxidation reaction on the malodorous gas, so that the malodorous gas is degraded and converted into low molecular compounds, water and carbon dioxide. The air duct is exhausted to the outside.
       4. Use high-energy UV beam to split the molecular bonds of bacteria in the malodorous gas, destroy the nucleic acid (DNA) of bacteria, and then carry out oxidation reaction through ozone to completely achieve the purpose of deodorization and killing bacteria.

Fou.equipment characteristics
       1. Modular design, flexible and simple: The instability and complexity of various exhaust gas properties are fully considered, providing greater feasibility, reliability and flexibility for engineering design, matching, installation, commissioning, maintenance, etc. . According to the collected exhaust air volume, wind speed and exhaust gas concentration, the number of exhaust gas UV purification modules can be flexibly configured, and the purification treatment efficiency is high. It adopts the form of drawer plug-in installation, and the accessories are unified, and the installation and maintenance are convenient. Spare parts can be maintained or replaced online, which is convenient and flexible, easy to operate, practical and effective.

       2. Safe, reliable and adaptable: Due to the principle of photolysis, the module adopts explosion-proof treatment, which eliminates potential safety hazards, and has good fire-proof, explosion-proof and anti-corrosion performance (all stainless steel 304# structure), and the equipment performance is safe and stable. Through reasonable module configuration, it can be widely used in various types of organic waste gas and malodorous gas purification treatment. This equipment does not have any mechanical device, no movement noise, and can work continuously 24 hours a day. In addition to regular inspection and maintenance, there is no need for special personnel to manage and operate, the maintenance and energy consumption costs are low, and the purification treatment effect has obvious advantages.
