■ Chemical deodorization process works: chemical odor technology, also known as acid purification technology, is the stench of gas through the scrubber deodorizing acid and alkali washing. Typically, water soluble or partially removing only sparingly water-soluble malodorous substances such as ammonia and the like; ammonia, and amines may be removed pickling alkaline malodorous substances; caustic is suitable for removing hydrogen sulfide, lower fatty acids and other acidic malodorous substances. Therefore, in order to completely remove the exhaust gases present in the different types of malodorous substances, usually be a multi-stage chemical pickling and alkaline cleaning Wash in series deodorization. Major components of the chemical composition and the use of odorous liquid is an irreversible chemical reaction to generate a new odorless substance in order to achieve the purpose of deodorization. See the following: H2S + 2NaOH + 4NaCLO Na2SO4 + 4NaCL + 2H2O H2S + NaCLO NaCL + H2O + S 2NH3 + H2SO4 (NH4) 2SO4 NaClO + (CxHyOz) NaCl + CO2 + H2O ■ chemical deodorant process consists of: ◆ deodorization tower bottom for circulating water, above the water tank to the intake port, the overhead for the washing liquid inlet and the nozzle connection, towers enclosing an inert solid bar, called the column packing filler provides a large gas-liquid contact area, malodorous gases by import side filler inward diffusion, reverse flow through the gap filler and liquid mist spray, "fluid", "gas" in close contact with the two-phase gas pollutant molecules contained in the tower circulating washing liquid is absorbed , purified gas is discharged after purification tower defogging defogging layer, into the fan to the chimney emissions. On the other hand, the exhaust gas pollutants with the bottom of the circulating liquid into the circulating water tank, after a certain concentration of pollutants discharged into the circulating water to the wastewater treatment system. Gas component based on factors, concentration, temperature, PH value, etc., the tower may be PP, FRP, PVC, SUS304, SUS316, SUS316L and so on. ◆ external chemical deodorization tower with automatic dosing system, the system consists of drug pumps and the tank components. Drug pump working liquid concentration by circulating fluid at the bottom of the deodorization tower control, liquid concentration is lower than required for the reaction gaseous pollutants, drug pumps work automatically, in accordance with a predetermined dose of a certain amount of liquid. ◆ whole system consists of a deodorant and automatic control system, control the fan start and stop; circulating pump start and stop; PH value of the circulating fluid, drain solenoid valve switches. The system is optional relay control and PLC control, can provide a variety of communication protocols based on customer demand. ■ Chemical deodorization process Scope: Chemicals and contain chemicals or experimental sites; metal plating factory; steel, tubes, plates, industrial products, wire pickling ground or surface treatment generated in the production process, sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, chromic acid, and sulfur oxides, nitrogen oxides, carbon oxides, and other gases cyanide treatment, the printing ink industry VOCS, have better treatment effect. ■ Chemical deodorization process advantages: adaptable to a wide range of concentrations of malodorous gases shock, small investment, small footprint, clean thoroughly, purification rate of stench.
