Odor waste gas treatment equipment technology in food processing plants


Food factory waste gas treatment equipment can eliminate odors and odors. Using a new waste gas washing technology, combined with UV photolysis equipment, waste gas washing tower and activated carbon adsorption tower. The waste gas treatment equipment of the food factory is pretreated by a front-end biological enzyme spray washing tower, and a nano-photocatalyst oxidation filtration system is installed at the back end.

In this way, photons of different energies can be generated by a special excitation light source, and the molecules of the odorous substances can be dissociated and excited under the bombardment of a large number of energy-carrying photons by the strong absorption of the photons by the odorous substances. The photons are used to decompose oxygen molecules in the air to generate free oxygen, namely active oxygen. Because the positive and negative electrons carried by free oxygen are unbalanced, they need to be combined with oxygen molecules to generate ozone.

exhaust gas cleaning system

The working process of waste gas treatment equipment in food processing plants is as follows:


Under the action of the light quantum, ozone can generate a large number of active groups such as new ecological hydrogen, hydroxyl oxygen, active oxygen, and some odorous substances can also react with the active groups, and finally be converted into harmless substances such as CO2 and H2O, so as to achieve complete The purpose of removing odorous gas. Because the average energy of the photons generated by the excitation light source is 1eV~7eV, proper control of the reaction conditions can realize the chemical reaction that is generally difficult to achieve or make the slow speed very fast, which greatly improves the efficiency of the reactor.


The odorous gas is introduced into the photon purification device by the collection system. After a series of reactions are induced by the photons generated by the special excitation light source, the odorous substances are decomposed and converted into harmless components such as CO2 and H2O. The device is already a powerful device. Green environmental protection air purification device. There is no secondary pollution, and the exhaust gas after the reaction is mainly nitrogen, oxygen, water, carbon dioxide and other harmless gases.


The waste gas is collected by the pipeline and then enters the biological enzyme washing tower. The waste gas is first sprayed and washed by the biological enzyme washing tower. The circulating water in the spray tower communicates with the circulating water pool, which can regularly remove the paint floating to the water surface in the pool. After the waste gas is treated by the spray washing tower, the waste gas enters the Dongsheng light hydrogen ion tower. The internal structure of the light hydrogen ion tower is a light hydrogen ion catalytic oxidation device.


The photohydrogen ion catalytic oxidation device can generate a large number of active groups of high-energy ion agents. Paint, benzene, toluene, xylene, resin, methyl ethyl ketone, aldehyde, additives, etc. chemically react with the active free radical groups, and are decomposed into Harmless gas carbon dioxide and water. This solution not only has high treatment efficiency, but also can effectively remove dust, paint and pollutants such as benzene, toluene, xylene, methyl ethyl ketone, aldehyde, and additives. After each treatment, it can be discharged up to the standard. The exhaust gas treatment equipment has small wind resistance and low operation and maintenance costs. , is a very advanced and superior waste gas treatment solution.
