Description
Technical Field
The utility model belongs to the technical field of hazardous waste gas treatment, and particularly relates to a hazardous waste gas treatment device containing VOCs.
Background
The VOCs gas and malodorous gas treatment technology of the existing organized emission mainly comprises the following steps:
the physical method comprises the following steps: adsorption methods such as zeolite, activated carbon, microlite, silica gel, and molecular sieve.
Chemical method: the chemical spraying and washing are adopted, and two reactions of oxidation and reduction are involved. The gas/liquid phase gas reversely contacts and reacts to transfer to the liquid phase, and the chemical agent is used for neutralization and oxidation reaction with acid-base substances and malodorous components in the gas. The waste liquid can cause secondary pollution and is required to be treated by water quality to reach the discharge standard.
The method for extracting plant liquid comprises the following steps: essential oil extracted from natural plants for inhibiting malodorous gas. The plant liquid waste gas treatment and deodorization technology is applicable to various open spaces; the disadvantage is that the operation cost is too high, and the treatment is not thorough.
Biological method: biological washing, drip filtration and filter bed. The special microbial flora screened manually is fixed on biological carrier, and organic matter in gas phase is transferred to liquid phase or solid phase biomembrane for absorption by microbe and oxidative decomposition into final product of carbon dioxide, water, etc. The three modes of biological washing, drip filtration and filter bed method mainly differ from the state of microorganism and the state of liquid. Biological methods are economical only when dealing with low concentration, readily biodegradable organic gas phase contaminants, and have poor versatility. The biological method has low operation cost and does not produce secondary pollution. However, the disposable investment cost is high, the occupied area is large, and the disposable investment cost is easily influenced by climate conditions.
Low temperature plasma process (chemical process): the low-temperature plasma formed by high-energy ion beams and electron beams generated by using a spiral microwave low-temperature cold light technology enters the interior of molecules, opens molecular chains and damages the principle of molecular structure, and the molecules in waste gas are bombarded by the principle of equivalent emission and recovery at the speed of 300-3000 ten thousand per second, so that a series of complex chemical reactions such as oxidation and the like occur, and the malodorous gas with low concentration is purified. The occupied area of the equipment is large, and the electricity consumption is large; the application has a great potential safety hazard when being applied to flammable and explosive gases.
Combustion (oxidation) (chemical process): direct, catalytic, regenerative combustion; the combustion method can thoroughly purify pollutants at high temperature (more than or equal to 850 ℃), recovers heat, has high investment and operation cost, is suitable for occasions with small air quantity (the waste gas quantity is reduced by adopting a pre-concentration process generally) and higher concentration, and has incomplete deodorization effect if the structure of the reaction chamber is slightly poor. The catalytic combustion process decomposes the exhaust gas at 300-500 deg.c in a catalyst bed. There are restrictive demands on the composition of the exhaust gas because catalyst poisoning easily occurs.
Adsorption method (physical method): the adsorbent is zeolite molecular sieve, activated carbon, microlite, silica gel, other molecular sieves, etc. The adsorption capacity in the adsorption method is usually small and can be regenerated and reused. Activated carbon is the most common adsorbent, is commonly used for low-concentration waste gas treatment, and can effectively remove organic volatile matters, hydrocarbon substances, chlorocarbon, oxygenated hydrocarbon (except formaldehyde) and other odor. The organic matters are adsorbed on the surface of the porous solid to remove odor, the operation temperature is preferably kept below 40 ℃, and impurities such as water vapor, dust and the like can influence the adsorption effect.
UV photocatalytic purification (chemical process): the UV photolysis oxidation method is to utilize ozone UV light beam to irradiate waste gas, under the irradiation of high-energy ultraviolet light beam, crack ammonia, trimethylamine, hydrogen sulfide, methylthio, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, aldehyde, ketone, phenol and the like in the malignant gas, sulfide H2S, VOC is a molecular bond of benzene, toluene and xylene, so that pollutant molecules in a free state are oxidized with ozone to be combined into small-molecular harmless or low-harmful compounds such as CO 2、H2 O and the like. Thereby achieving a reduction of the malodor concentration in the exhaust gas. Has good deodorizing effect and high-efficiency disinfection and sterilization effect.
To sum up, in order to solve the above problems, we propose a hazardous waste gas treatment device containing VOCs.
