Zhaoqing electronic generator exhaust gas treatment equipment industrial waste gas treatment purification

 (A) process selection Description: generator mainly uses diesel fuel, mainly diesel fuel in the combustion process produces sulfur dioxide, nitrogen oxides and soot, exhaust gas, using water spray up to environmental law this off-gas desulphurization dust control, while According to this exhaust gas dissolved in water to make the water acidic, corrosive characteristics of large, Dongguan City, up to the design of the main environmental protection equipment made of stainless steel production, and dual base (sodium hydroxide + lime) solution spray, acid-base and to reduce the corrosion of the equipment. (B) spray tower packing process principle of the dual-alkali absorption process, the process with sodium hydroxide / lime solution as an absorbent to deal with, to new and efficient dust desulfurization tower packing equipment as the main body, works as follows: diesel combustion smoke generated under the action of the generator exhaust pressure by the lower tangential direction into the flue gas purification from the bottom, after contact with the film formed by the spray nozzle, (carbon black) trapped fluid absorption, and Meanwhile, liquid mist in the cyclone, driven also rotates, dust particles under the influence of fluid mist becomes wet heavier, by the action of centrifugal force and inertia force of thrown to the outer wall, so that dust and gas separation, wet dust discharged from the bottom of the outfall, purified exhaust gas discharge from the desulphurization equipment chimney outlet air. In a chemical reaction to control the PH value is more important direct influence of the absorption of SO2, PH low absorption capacity is too low, the operation should control PH maintained at 10-11. Dust desulfurization equipment through the liquid absorbed, the self-flowing and pool, fully react at the cyclone effect of inertia, and finally sedimentation tanks and sludge sedimentation its impurities, regular cleaning, clear liquid into the lye tank (adjusted PH) again recycling. Fourth, the generator smoke purifier has the following advantages: 1. High dust removal and desulfurization efficiency, water with an alkaline washing, desulfurization efficiency up to 85%; 2. equipment footprint, easy installation; 3. water, electricity lower targets; 4. corrosion, wear, long service life; 5. reliable equipment operation, maintenance is simple and convenient. Fifth, the main equipment selection 1, spray tower (stainless steel scrubber) Material: Stainless Steel for 2, 3 spray pumps, circular tanks (including neutralization tank, lye tank, sedimentation tank) 4, dissolved drug groove 5, packing layer its generator room equipped with two diesel generators. Wherein the two generators are supporting a generator exhaust gas treatment system, which 310KW generator supporting air volume 4000m3 / h of exhaust gas treatment system set, 800KW generator supporting air volume 10000m3 / h of exhaust gas treatment system set. 2, the generator exhaust emission standard processing execution "air pollutant discharge standards" GB16297-1996 second period two standard SO2: ≤550mg / m3 of particulate matter: ≤120mg / m3 Ringelman degree: ≤1 level power machine 0 # diesel fuel, mainly diesel fuel in the combustion process produces sulfur dioxide, nitrogen oxides and soot, exhaust gas, I recommend using a water spray method this off-gas desulphurization dust control, while according to this exhaust dissolved After the water so that the water is acidic, corrosive characteristics of large, I designed the main equipment used stainless steel production, and dual base (sodium hydroxide + lime) solution spray, acid-base and reduce the corrosion of the equipment. Motor exhaust port fitted with silencers and heat exchangers, silencers and exhaust through a heat exchanger into the cyclone spray tower, spray water to enhance the circulation pump into the spray tower through spray nozzle spiral, spiral Cone exhaust water film in full contact with the tower and the plate surface chemical reaction, purified flue gas exhaust pipe emptying directly from the top of the spray tower; wash were settling tank sedimentation tank into the circulation by the circulation pump lifting spray water recycling, settling sewage regularly discharged into the sewage treatment plant emissions purification system. Spray water system installed pH automatic monitoring system, on-line monitoring of the circulating water pH value, the automatic control the amount of alkali, the pH value remains constant, to ensure stability of the system.
