Animal slaughterhouses will produce a lot of foul odors when slaughtering and processing animal viscera and fur. The stench is unbearable and will harm the factory environment and the health of workers. For animal slaughterhouses, are generally large and scattered. If the control is not good, the whole slaughter and processing area will be filled with this unpleasant stench. For the stench gas, step d is to collect the waste gas, the purpose is to make all the sources of the stench gas that can emit the stench gas. Closed and negative pressure odor collection, the second step d is to deal with the collected odor. The following is a detailed plan for the treatment of slaughterhouse waste gas:
Through the collecting tuyere, conveying duct and fan, the malodorous gas is collected. Send each processing unit separately to purify in order to achieve the goal of environmentally friendly emissions.
Step 1: The gas enters the composite photocatalytic oxidation equipment, and the front end of the photocatalytic equipment is equipped with a primary filter to remove grease and large particles in the exhaust gas. Most of the odorous hydrocarbons are oxidized and decomposed by oxygen free radicals and hydroxyl free radicals. ；
Step 2: The malodorous gas generated in each treatment structure is sent to the chemical scrubber under the action of the suction port, the conveying duct and the fan. (Add dilute sulfuric acid to remove ammonia and other reducing substances that are easily soluble in water)
Step 3: The waste gas treated by the pickling equipment is sent to the pickling equipment. (Add sodium hydroxide to remove hydrogen sulfide, acids and alcohols);
Step 4: The peculiar smell of gas that has been treated before still leaves a big odor pollution problem. At this time, the plant deodorizing liquid can be used, and the plant deodorizing liquid can be added to the two previous washing towers. Under the action of negative pressure, the deodorizing particles in the plant deodorizing liquid will quickly and actively capture the smelly gas molecules in the air and wrap the smelly particles. The particle is a natural oily deodorizing molecule, and the particle non-covalently combines with the odor molecule through intermolecular non-polar interaction, thereby greatly stabilizing the molecule, reducing its activity and irritation, and achieving complete removal of the odor.
Step 5: The treated exhaust gas is discharged at an altitude of 20 meters through the chimney.
Acid and alkaline exhaust gas is treated with chemical scrubber equipment based on the principle of acid-base neutralization, with a treatment efficiency of over 98%.
The material of the scrubber is corrosion-resistant PP, which is designed as a vertical tower to treat acid and alkali waste gas.
