Description

Photo-oxygen catalytic technology for waste gas and odor deodorization equipment

technical field

The utility model relates to the field of waste gas and stench treatment, in particular to a photo-oxygen catalytic technology for treating waste gas and stench deodorization equipment.

Background technique

Stench refers to unpleasant smell. So far, there are more than 4,000 kinds of stench substances that can be felt by human sense of smell, and dozens of them are more harmful to human health. The foul-smelling substance makes people have difficulty breathing, nausea and vomiting, irritability, dizziness, and even fumes people down. When the concentration is high, it can cause people to suffocate to death. Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life, especially chemical plants, paper mills, foundries, waterproof material factories, garbage dumps, sewage treatment plants, tire factories, pharmaceutical factories, as well as coking plants and oil refineries Factories, etc., discharge exhaust gas and stench, which seriously pollutes the environment and affects human health.

In the prior art, technologies such as biological decomposition method, activated carbon adsorption method, plasma method and plant spraying liquid deodorization method are generally used for the treatment of stench and waste gas.

The biodegradation method mainly uses circulating water flow to dissolve the odorous gas pollutants into the water, and then cultivate microorganisms in the water culture bed to degrade the pollutants in the water into low-harm substances. The microbial activity is reduced, but its deodorization efficiency is low, and the deodorization The purification effect is very unstable, and special microorganisms need to be cultivated to treat one or several gases with similar properties. The operation and maintenance costs are relatively high, and the service life is short. Frequent injection of chemicals is required to maintain microbial activity, and the requirements for circulating water are relatively high. Otherwise, if the microorganisms die, it will take a long time to re-cultivate, which will easily cause secondary pollution.

The activated carbon adsorption method mainly uses the characteristics of the developed internal pore structure and large surface area of activated carbon to adsorb the odorous gas molecules passing through the activated carbon pool, but the activated carbon is very easy to be saturated, and generally fails within a few days, and the activated carbon needs to be replaced frequently, and waste activated carbon needs to be found The treatment method, its operation and maintenance costs are very high, and it is easy to cause secondary pollution.

The plasma method mainly uses the principle of high-voltage electrodes to emit ions and electrons to destroy the structure of odorous molecules, and bombards the odorous molecules in the exhaust gas, thereby cracking the odorous molecules and achieving the purpose of deodorization and purification. Explosion, its deodorization and purification efficiency is low, and this method consumes a lot of electricity, and also needs to be cleaned, and the operation and maintenance cost is high.

The deodorization method of plant spraying liquid is mainly to spray plant extracts, namely deodorants, into the space where malodorous gases are generated, to neutralize and absorb the malodorous gases, and achieve the purpose of deodorization. The spraying liquid needs to be added regularly, and equipment maintenance is required. The operation and maintenance costs are high, and the efficiency of deodorization and purification is low.

Therefore, prior art still needs further improvement and development.
