TiO22The photocatalytic oxidation is active hydroxyl (OH) and other active oxidation species (O)2-，·OOH，H2O2) The result of the combined action. In TiO2The OH group generated on the surface has high reactivity and reaction energy higher than that of various chemical bond energies in organic matters, and is added with O2 -，·OOH，H2O2The synergistic effect of the active oxidation substances can quickly and effectively decompose the organic substances.
The rough reaction mechanism is:
H2S+O2、O2-、O2+→SO3+H2O
NH3+O2、O2-、O2+→NOx+H2O
VOCs+O2、O2-、O2+→SO3+CO2+H2O
the ultraviolet wavelength of the high-energy ultraviolet lamp is 182nm, 254nm or 365 nm.
The activated carbon adsorption structure is internally filled with activated carbon, and the activated carbon is fine carbon particles, has a large surface area, and has finer holes, namely capillaries. Such a capillary tube has a strong adsorption ability, and can sufficiently contact a gas (impurity) because the surface area of the carbon particle is large. When the gas (impurities) is adsorbed by the capillary tube, the purification effect is achieved (the main effect is to remove most of benzene series, non-methane total hydrocarbon, organic matters such as VOCs and the like, the odor concentration and the like in the waste gas).
The gas distribution device 30 distributes gas to the odor controller 40, the Vaportek odor controller 40 is a core device, and the Vaportek deodorization membrane is a main deodorization unit. Odor removing particles are uniformly distributed on the surface of the membrane through VP, and the odor is rapidly removed by utilizing the air convection power, and meanwhile, other external substances cannot be sucked, so that the naturalness of the plant extracting solution is kept forever. The deodorizing particles in the waste gas can quickly and actively capture the odor gas molecules in the air and wrap the odor particles. The common odor molecules are mostly small molecular organic matters (esters, alcohols, aromatic hydrocarbons and the like), and also comprise part of inorganic small molecules such as ozone, ammonia, hydrogen sulfide, hydrocarbons and the like, and the odor molecules have high activity on the surface of olfactory cells and strong irritation, and still have strong olfactory pollution capacity even under the premise that the concentration of each odor component reaches the standard and is discharged, namely the odor molecules have the characteristics of low pollution concentration and high odor intensity. Vaportek particles are natural oily deodorized molecules, and the particles are in non-covalent combination with odor molecules through intermolecular nonpolar interaction, so that the molecules are greatly stabilized, and the activity and the irritation of the molecules are reduced. Further, the increase in specific gravity after the binding is solved by the sedimentation effect. The process is different from chemical reaction process to generate a third substance and masking effect, does not cause secondary pollution, and can thoroughly remove odor.
When the rubber shock pad is used for baking the waste gas purifying device of the line, the collected waste gas is sent to the alkali liquor washing device 10 under the action of the suction port, the conveying air pipe and the fan for treatment, sodium hydroxide is selected as circulating liquid in the treatment section and is used for washing odor molecules in spraying solution and gas to generate gas and liquid contact, SO that odor components in the gas phase are transferred to the liquid phase, odor substances are removed by neutralization, oxidation or other chemical reactions of chemical agents and the odor components, and SO in the waste gas is removed2、NOxMethyl mercaptan, methyl sulfideRemoving waste gas components dissolved in the alkali liquor, such as methyl disulfide and the like.
The waste gas washed by the alkali liquor washing device 10 belongs to a gas-liquid mixed state, and most of water vapor in the gas needs to be removed through the treatment of a high-efficiency dehydration and dehumidification layer in order to avoid influencing the next treatment section. Due to the inertia effect of the rising of the waste gas, the water vapor collides with the dehydration layer and is attached to the surface, so that the liquid drops are larger and larger, and the gravity sedimentation is achieved. (the main function is to intercept floccules in the gas and remove most of water vapor in the gas)
The dehydrated waste gas is pumped to the low-temperature plasma structure of the integrated equipment 20, the waste gas firstly passes through the low-temperature plasma excitation area, high-energy electrons are generated under the acceleration action of an electric field, and when the average energy of the electrons exceeds the molecular chemical bond energy of a target treatment object, the molecular bonds are broken, so that the aim of eliminating gaseous pollutants is fulfilled. (mainly used for removing benzene, toluene, xylene, non-methane total hydrocarbons, VOCs and other organic matters in a part of waste gas).
The photocatalytic oxidation of TiO2 formed in the exhaust gas after low-temperature plasma decomposition under the lamp irradiation of high-energy ultraviolet lamp beams is the result of the combined action of active hydroxyl groups (. OH) and other active oxidation substances (. O2-,. OOH, H2O 2). OH groups generated on the surface of TiO2 have high reactivity and higher reaction energy than various chemical bond energies in organic matters, and can quickly and effectively decompose the organic matters by the synergistic effect of O2-,. OOH and H2O2 active oxidation substances. (main function: removal of easily decomposed and oxidized exhaust gas components (benzene, toluene, xylene, non-methane total hydrocarbons, VOCs, etc., and only good disinfection and deodorization effects) from a part of exhaust gas)
The waste gas after the composite photocatalysis is pumped to an activated carbon adsorption structure, the activated carbon has a large surface area, and the carbon granules also have finer holes, namely capillaries. Such a capillary tube has a strong adsorption ability, and can sufficiently contact a gas (impurity) because the surface area of the carbon particle is large. When the gas (impurities) is adsorbed by the capillary, the components which have stable molecular structure and cannot be biodegraded are removed.
The odor gas pretreated by the previous stages still has the biggest odor pollution problem. At this time, the Vaportek odor controller 40 is adopted, and a medium-low pressure centrifugal fan 50 is used for blowing air (realizing variable frequency control), so that the deodorizing particles in the odor controller 40 are taken away, odor gas molecules in the air are rapidly and actively captured, and the odor particles are wrapped. Vaportek particles are natural oily deodorizing molecules, and the particles are in non-covalent combination with odor molecules through intermolecular nonpolar interaction, so that the molecules are greatly stabilized, the activity and the irritation of the molecules are reduced, and the odor is thoroughly removed. (main function: removal of malodors in exhaust gas to the point of emission).
The treated waste gas reaching the standard is discharged by being led to a height of more than 15 meters through a chimney 60.
The invention also relates to a waste gas purification method for the baking line of the rubber shock pad, which comprises the following steps:
