Description
Technical Field
The utility model relates to a device and method of retrieving especially relate to a device that is used for complicated organic waste gas treatment in tank field and resource recovery.
Background
The incineration method is generally applied to the treatment of high-concentration industrial waste gas and process tail gas, but the secondary pollution problem of gas to clothes and smoke of an incinerator exists in the application process. The condensation method is mainly suitable for recovering high-concentration high-boiling-point organic matters, has no effect on low-concentration and low-boiling-point volatile organic matters, and has higher requirements on equipment. The chemical washing method is to add oxidant such as NaClO, NaOH, etc. to oxidize some organic sulfur and organic amine substances in the waste gas into compounds with lighter taste or higher solubility, and is suitable for treating organic waste gas with large air volume and medium-high concentration. The practical effect shows that the purification efficiency is not high, and secondary pollution is easy to form. The photocatalytic oxidation being TiO2The quasi-catalyst can generate free groups with high chemical activity and sterilization and deodorization under the irradiation of ultraviolet light, has low investment, high efficiency, stability and no secondary pollution, but has higher requirement on waste gas and is influenced by the fixing mode and selectivity of the catalyst. The biological method is to degrade organic components in the waste gas into CO by using microorganisms such as fungi and bacteria2And H2O and the like, but has large occupied area, and has great problems in the treatment of hydrophobic and difficultly biodegradable substances.
The adsorption method has the characteristics of small adsorption heat, large adsorption quantity, no need of activation energy in the adsorption process, fast adsorption and desorption, reversible process and the like, and is widely applied to the fields of petrochemical industry, pharmaceutical industry, environmental protection and the like.
The principle of physical adsorption is caused by the forces acting between the adsorbate and the adsorbent molecules, and is therefore also called van der waals forces, caused by the attractive forces between the molecules. The adsorption effect is closely related to the property and surface size of the adsorbent, the property and concentration of the adsorbate, and the like.
Activated carbon adsorption is a typical physical adsorption process and was first applied in wastewater treatment. However, as technology advances, its range of applications is increasing. The active carbon has developed pore structure, large specific surface area and strong adsorption capacity. The main types of the material are as follows according to the appearance and shape: granular, columnar, powdery, and fibrous.
The organic waste gas is treated by the activated carbon because of the capillaries in the carbon granules, and the capillaries have strong adsorption capacity and can be fully contacted with impurities in the gas. When the impurities meet the capillary tube, the impurities are adsorbed, thereby playing a role in purifying the waste gas.
Activated carbon fibers are an emerging technology in recent years, but due to their own properties and requirements for adsorption equipment, they are not widely used in the treatment of organic waste gases with high concentrations.
So far, most of industrial enterprises still use the methods of active carbon adsorption, increasing air quantity of air outlet to dilute organic matter concentration and then emptying, and the method can be effective in short time. However, once the desorption of the activated carbon is insufficient, the waste gas is only diluted, and the emission requirement cannot be completely met, so that the serious influence on the atmospheric environment is caused, and the great economic loss is caused to enterprises.
In the prior art, after the absorbent absorbs the waste gas, the content of organic matters is increased, the absorption efficiency is reduced, and the waste gas treatment capacity is weakened, so that the absorbent needs to be replaced periodically, the operation cost is increased, and secondary pollution is easily caused.
