Application of waste gas treatment equipment in environmental protection company and treatment method of organic waste gas
1. Instructions for the use of waste gas treatment equipment
When the environmental equipment operation project is not working normally, the waste smoke and dust pollutants produced in the production process can not be effectively regular treatment and directly discharged into the nature will inevitably form different degrees of damage and influence on the local environment. Therefore, after the waste gas treatment equipment is formally put into operation, the influence on the local environment is mainly manifested in the problem of waste gas treatment equipment, improper operation of workers and power outage. In order to prevent the pollution caused by the cause of operation, the operator has a certain knowledge of environmental protection and the common sense of mechanical operation. The professional skill personnel should have to undergo strict specialized training. Determine the contingency plan for good luck when a project has a temporary failure and minimize the direct impact on the surrounding environment.
The commonly used treatment methods for waste gas treatment equipment are:
The principles of waste gas treatment include activated carbon adsorption, catalytic combustion, catalytic oxidation, acid-base neutralization, plasma and other principles. Dream environmental protection focus on waste gas, dust, sewage and other environmental protection projects, for enterprises to provide a dragon type solution and perfect after-sales service process, got the consistent praise of the enterprise.
1. One of the methods of masking of waste gas treatment
Deodorization principle: strong aroma and odor are combined with odor to achieve the effect of masking the odor and making it acceptable. Scope of application: It is suitable for the occasion where the influence of odor with low concentration needs to be eliminated urgently and temporarily. The odor intensity is about 2.5 and there is no organized emission source. Advantages: it can eliminate odor effects as soon as possible, with great flexibility and low cost. Shortcoming: the odor is not effectively eradicated.
2. The two dilution diffusion method for treatment of waste gas
Deodorization principle: will be odorous gas through the chimney to the atmosphere, or with odorless air dilution, reduce the concentration of odorous substances to reduce odor. Scope of application: it is suitable for treating medium and low concentration of odorous gas with organic emission. Advantages: low cost and simple equipment. Disadvantages: susceptible to meteorological conditions, odorous substances still exist.
3. The three way of waste gas treatment is thermal combustion and catalytic combustion.
The principle of deodorization: the odor material and fuel gas are mixed fully at high temperature to realize the scope of complete combustion: it is suitable for combustible gas to deal with high concentration and small gas. Advantages: high purification efficiency, foul smell substances are thoroughly oxidized and decomposed. Disadvantages: the equipment is easy to corrode, consume fuel, and has high processing cost. It is easy to form two pollution.
4. Four water absorption method for treatment of waste gas
Deodorization principle: the use of odor in some substances easily soluble in water characteristics, so that odor components directly in contact with water, thus dissolving in water to achieve deodorization purposes. Scope of application: odorous gases from water-soluble and organic sources. Advantages: simple process, convenient management, low operation cost and two pollution. Disadvantages: low purification efficiency, should be combined with other technologies, and have poor effect on mercaptan and fatty acids.
5. Five liquid absorption method for treatment of waste gas
Deodorization principle: the use of some substances in the odor and chemical reaction of the liquid to remove some odor components. Scope of application: it is suitable for dealing with odors of high volume and high concentration. Advantages: it can handle some odor components in a targeted way, and its technology is more mature. Disadvantages: purifying efficiency is not high, consumption of absorbent, easy to form and two times pollution.
6. The six adsorption method for the treatment of waste gas
Deodorization principle: the adsorption of odorant is used to transfer odorous substances from gaseous phase to solid phase. Application: it is suitable for treating odor gas with low concentration and high purification requirements. Advantages: high purification efficiency, which can handle multi component odorous gases. Disadvantages: adsorbents are expensive, difficult to regenerate, and require lower temperature and dust content for odorous gases to be treated.
7. The seven biofilter deodorization method for waste gas treatment.
Deodorization principle: after the pretreatment process, such as removing dust, humidifying or cooling, the foul gas passes the filter bed from the bottom to the bottom, and the odor gas is transferred from the gas phase to the water microorganism mixed phase, and is decomposed by the microbial metabolism that is fixed on the filter material. Scope of application: the most commonly used biological deodorization method is the most studied and the most mature technology. It can be subdivided into soil deodorization, composting deodorization, peat deodorization and so on.
Advantages: low cost of treatment. Disadvantages: large area, regular replacement of filler, deodorization process is not easy to control, it is easy to problem after a period of time, and it is difficult to deal with the treatment of hydrophobic and biodegradable materials.
8. Eight biological trickle filter for waste gas treatment
Deodorization principle: the principle is similar to the biofilter, but the filter material used is inert material such as polypropylene pellets, ceramics, charcoal, plastic and so on. Scope of Application: Only microorganisms degraded for certain odorous substances adhere to the packing, and no biofilter mixing will occur.
Advantages: the consumption of filter material and organic matter by microorganisms. Shortcomings: the number of microbes in the pool is large, can withstand the pollution load larger than the biofilter, the inert filter can not be replaced, the pressure loss is small, and the operating conditions are very easy to control the need to continue to add nutrients, and the operation is complex, making its application limited.
9. Nine of washing waste activated sludge deodorization method.
Deodorization principle: full contact between the odorous substances and the mixed liquid containing suspended solids, so that it can be removed from the odor in the absorber.
