Waste (odor) gas treatment technology and equipment
chemical deodorization
Chemical washing and deodorization technology, also known as acid-base purification technology, deodorizes odorous gases by washing them with acid and alkali through a scrubber. Usually, water washing can only remove odorous substances that are soluble or partially soluble in water, such as ammonia; acid washing can remove alkaline odorous substances such as ammonia and amines; alkali washing is suitable for removing acidic odors such as hydrogen sulfide and low-grade fatty acids. substance. Therefore, in order to completely remove various odorous substances present in the exhaust gas, a multi-stage chemical washing method of acid washing and alkali washing in series can usually be used for deodorization.
VOC catalytic combustion
Catalytic combustion treatment technology is a typical gas-solid phase reaction, and its essence is deep-concentration oxidation involving active oxygen. During the catalytic oxidation process, the adsorption on the catalyst surface enriches the reactant molecules on the catalyst surface. The catalyst reduces the activation energy, accelerates the oxidation reaction, and increases the rate of the oxidation reaction. Under the action of a specific catalyst, organic matter undergoes flameless oxidative combustion at a lower ignition temperature (250-300°C), and is oxidized and decomposed into CO2 and water. and releases a lot of heat.
biological deodorization
The core of the biological filtration and purification system is a high-efficiency biological filter tower, composite biological fillers and microbial strains that are conducive to biological attachment and growth, so that microorganisms can form biofilms on the surface of the composite biological fillers under suitable environmental conditions in the biological filter tower. The microorganisms in the membrane use inorganic and organic matter in the waste gas as carbon sources and energy, maintain their life activities by degrading odorous substances, and decompose odorous substances into water and carbon dioxide, water, minerals and other odorless substances to purify odorous gases. Purpose.
