STPF type waste gas treatment tower
Service target: 1. Purification and treatment of acidic pungent exhaust gas in mechanical processing, electroplating, and surface treatment workshops
Product details
- The exhaust gas purification tower is a product of our company. The company has formed a complete range of exhaust gas purification equipment, including packed scrubbing tower, cyclone tower, power wave scrubbing tower, photo oxidation scrubbing tower, integrated scrubbing tower, etc. It can adapt to various corrosive environments and high-tech products of various exhaust gas types. It is a complete set of equipment designed based on the pollution of acidic and alkaline gases generated by electroplating and machining surface treatment processes. It is also a new generation of exhaust gas treatment equipment improved by our factory based on domestic and foreign exhaust gas treatment equipment and our years of acid mist treatment experience. This equipment can be combined and installed according to the characteristics of exhaust gas. The equipment has low resistance, low energy consumption, low noise, high treatment efficiency, and can treat hydrogen chloride gas（HCL）Hydrogen fluoride gas（HF）Ammonia gas（NH3）Sulfuric acid mist（H2SO4）Chromium acid mist（CrO3）Cyanuric acid gas（HCN）Alkali vapor（NaOH）Hydrogen sulfide gas（H2S）Sulfur dioxide（SO2）Gas and formalin（HCHO）Waiting for gas. At the same time, according to our company's unique process operation, volatile compounds can be processedVOCsTreatment of organic waste gas, malodorous gas and other non water soluble waste gas. The waste gas is forced into the equalizing chamber of the inner cylinder of the purification tower by the fan. After the first stage of spray treatment, the absorption liquid is sprayed on the upper part of the tower body, and the harmful gas entering the tower body at the lower part flows in reverse with the spray liquid, that is, the waste gas flows from bottom to top, and the spray liquid is sprayed from top to bottom, so that the vapor liquid contact is more sufficient. The overlapping double-layer filter material layer spraying and spray cross arrangement are adopted. The waste gas passes through the filler layer composed of flake ball fillers, and then passes through the second spray treatment, so that the gas-liquid two phases are fully contacted to produce absorption neutralization reaction, improving the purification efficiency. The treated waste gas is then subject to dehydration by the dehydrator and then discharged into the atmosphere to achieve the purpose of efficient purification, and the purified waste gas meets the environmental protection emission standards.

- An example of the absorption reaction of acidic waste gas is as follows:
- 1Hydrochloric acid waste gasHCI+NaOH→NaCI+H2O2
- 2Phosphoric acid waste gasH3PO4+2NaOH→Na2HPO4+2H2O
- 3Sulfuric acid waste gasH2SO4+2NaOH→Na2SO4+2H2O SO2+2NaOH→Na2SO4+H2O
- 4Nitric acid waste gas3NO2+H2O=2HNO3+NO+136.2kJ
- 5Chlorine gas exhaust gasCl2+2NaOH→NaCl+NaClO+H2O
