When Electroplating factory Waste gas treatment use UV light,which one is better? This is a lot of Electroplating factory boss`s problem.In the production process,it will produce toxic waste gas,such as dust emission,acid gas,alkaline waste gas,chromium waste gas,nitrogen oxide waste gas,cyanide waste gas an so on.

1. Dust emission:Mainly produce by sand blasting,grinding and polishing,have grain of sand,metal oxide as well as fibrous dust,ect.this kind of waste gas not only pollute the air,also can cause harm to the practitioners of the throat and lungs.

2. Acid gas:As a result of hydrocholoric acid.sulfuric acid and other acidic material for pickling,light and chemical polishing process.For example,hydrogen chloride, sulfur dioxide, hydrogen, hydrogen sulfide and phosphoric acid gas and acid fog.It has strong excitant gas which will harm to the operator throat,the trachea and lungs.Also will corrosion factory and equipment,polluted air or form acid rain.

3. Alkaline waste gas:In the process of electroplating,used sodium hydroxide,sodium carbonate and sodium phosphate and other Alkaline materials.Because of mainly by the heating process,Chemical degreasing,like electrochemical oil removal, strong alkali and cyanide electroplating electroplating,etc. Alkali fog stimulate for operater`s throat, trachea and lungs is large.

4. Chromium waste gas:Is produce by chrome plated process.Chrome fog has strong toxic and corrosive, caused great damage and pollution to human body and environment.The chrome fog through the respiratory tract inhalation in to the body, will irritate and corrosion the respiratory.It will cause the nose have a serious disease,such as Acute rhinitis, nasal perforation, pharyngitis, bronchitis, etc.If the skin touch chrome fog for a long time,also will cause dermatitis or eczema, chromium fog teratogenic, carcinogenic and mutagenic.

5. Nitrogen oxide waste gas:In the solution containing nitric acid pickling, the light, and in the polishing process of acid gas,nitric oxide through the respiratory system into the blood, intrude into red blood cells and hemoglobin which cause septicemia.At the same time, also will paralysis effects on central nervous system, inhaling high concentrations of nitric oxide can causes the death of animals. Nitrogen tetroxide and nitrogen tetroxide toxicity is three to four times larger than nitric oxide. Nitrogen tetroxide mainly harm for humen body mucous membrane,irespiratory system and nervous system.when the nitrogen tetroxide concentratios hight, it will made the people caugh,hemoptysis, causing pneumonia, lung water even choked to death.Besides, also can cause damage to the nervous system.

6. Cyanide waste gas: Produced by cyanide electroplating, such as cyanide copper plating, zinc plated and imitation gold, etc. Cyanide in the acid reaction, can produce more toxic hydrogen cyanide gas, although inhaled trace can cause person death.

Waste gas processing method:

XPES electroplating factory Waste gas treatment UV light is use in combina with waste gas processing equipment area.It can using High-energy high ozone UV ultraviolet light ray stench gas, change the fetor,such as Ammonia and trimethylamine, hydrogen sulfide, hydrogen sulfide and methyl mercaptan, sulfide, dimethyl disulfide, styrene, carbon disulfide and sulfur H2S, VOC, molecular chain structure of benzene, toluene, xylene.It is made The organic or inorganic polymer odorous compounds molecular chain,when it Under the high energy beam exposure to the sun's ultraviolet rays, degraded into low molecular compounds, such as CO2, H2O, etc.

Using High-energy high ozone XPES electroplating factory Waste gas treatment UV light beam Free oxygen decomposition oxygen molecules in the air,the reactive oxygen species, by free oxygen carrying electron-positron unbalanced so need to combine with oxygen, which produce ozone. UV+O2→O-+O*(reactive oxygen species)O+O2→O3(oPEzone). As is known to all the ozone oxidation of organic matter with a strong, for odorous gases and other irritating odor have immediate removal effect.
