Medical waste gas in the composition of complex, containing benzene, toluene, ethanol, ethyl acetate, hydrogen chloride and so on. Among them, benzene ring and halogen, in the premise of 400C or so, easy to produce dioxin, dioxin this kind of material is very chaotic, high melting point, extremely difficult to dissolve in water, is colourless and tasteless fat-soluble substances, so it is very easy to accumulate in organisms, medical waste gas treatment programme should be how to determine it? The following with the Everest blue editor to understand.
Medical waste gas treatment methods
According to the composition and characteristics of medical waste gas, the commonly used waste gas treatment solutions are absorption method, adsorption method, condensation method, biological method, photocatalytic degradation, combustion method and so on.
1. Absorption method is to choose the appropriate liquid absorber to remove gas pollutants, such as water to add acid and alkali liquids, surfactants, etc. made of absorbent, and pollutants will be absorbed and thus be purified. Usually used equipment for packing tower or spray tower. 2.
2. Adsorption method mainly uses porous adsorbent material to adsorb the pollutants in the waste gas, and there are many kinds of adsorbents. The most commonly used adsorbent in the furniture industry is activated carbon, which has the advantages of non-restrictive function and erosion resistance, and can be used to absorb large air volume and low concentration of organic waste gas, the disadvantage of which is that the adsorbent needs to be replaced on a regular basis.
3. condensation method is the exhaust gas condensation or adsorption concentration condensation, separation and recovery of valuable organic matter, mostly used for high concentration of organic waste gas treatment with recovery value. 4. biological method is the exhaust gas condensation or adsorption concentration, separation and recovery of valuable organic matter, mostly used for high concentration of organic waste gas treatment with recovery value.
4. biological method is the waste gas and microbial contact, by microbial capture degradation, oxidation, so that the pollutants decomposed into harmless inorganic substances. Because the organic waste gas components in the water solubility is low, the gas-liquid phase transfer there is a greater resistance, microbial treatment efficiency is low.
5. Photo-oxidation catalytic degradation technology is the use of catalyst photocatalytic activity, oxidation of target pollutants adsorbed on the surface of the catalyst, suitable for dealing with low concentration, large air volume gas. However, the photo-oxidation degradation product should be hydrophilic vocs, forming secondary pollution, treatment efficiency needs to be improved. 6.
6. Combustion method is the combustion and oxidation of organic matter in the exhaust gas, completely converted into carbon dioxide and water. Combustion method initial investment and operating costs are higher, less applied in the furniture industry.
Medical waste gas treatment programme
Generally, the combustion method is adopted for treatment, specifically the treatment process of activated carbon adsorption and desorption + co catalytic combustion.
Medical waste gas treatment process
Jet tower-->Dry filter-->Activated carbon adsorption and desorption-->CO catalytic combustion-->Chimney discharge
The above is the relevant introduction of medical waste gas treatment programme, the specific situation needs to be treated specifically, may not be applicable to all the requirements of the working conditions, mainly based on the air volume and concentration to determine, if you have the relevant needs, you can consult us through the right side of the contact information.
