Embodiment 1

[0051] First, the spray flow rate should not be too large to ensure that the catalyst particles are wet. Moreover, there is no water or a small amount of water in the catalyst layer, so that the bottom-up exhaust gas can be absorbed by the spray water containing a certain concentration of oxidizing agents, and the part that cannot be absorbed by the spray water is absorbed by the catalyst particles. The organic matter and oxidizing agent are degraded under the action of the catalyst to achieve the purpose of removing the organic matter in the exhaust gas.

[0052] The exhaust gas is passed into the air inlet 111 of the reaction tower 1 from bottom to top according to the speed V0≤10m / h, and the exhaust gas pressure should not be too high to ensure that the exhaust gas overcomes the resistance to discharge pressure.

[0053] The oxidizing agent is added to the outlet of the circulating pump 143 in a certain proportion through the dosing device 2 . The specific address can be d...

Abstract

The invention provides a VOCs (Volatile Organic Compounds) waste gas treatment device and method, which are used for removing organic matters in waste gas. The VOCs waste gas treatment device comprises a reaction tower, a gas inlet and a gas outlet are formed in the bottom and the top of the reaction tower respectively, a catalyst layer is arranged in the reaction tower, and gas entering the reaction tower from the gas inlet flows through the catalyst layer from bottom to top and is discharged from the gas outlet; a water distributor is further arranged at the top of the reaction tower and used for spraying water into the reaction tower from top to bottom, water mixed with chemicals flows into the reaction area from top to bottom, and waste gas meets the spraying water added with oxidizing chemicals from bottom to top in the reaction tower and is subjected to catalytic oxidation degradation reaction under the action of a catalyst; therefore, the organic matter is decomposed into carbon dioxide and water, and the purpose of removing the organic matter is achieved.

Description

technical field [0001] The present invention relates to the technical field of waste gas treatment, and more particularly, to a VOCs waste gas treatment device and method. Background technique [0002] Volatile organic compounds (VOCs, volatile organic compounds) are various organic compounds with boiling points ranging from 50°C to 260°C at room temperature. In general, VOCs refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10Pa and volatile at 20°C. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, which have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have unpleasant special odor, and have toxic, irritating, teratogenic and carcinogenic effects, especially benzene, toluene and formaldehyde, which can cause g...
