1. Absorption equipment The absorption method uses low volatile or non-volatile solvents to absorb VOCs, and then uses the difference in physical properties of VOCs and absorbents to separate.

2. Adsorption equipment When treating fluid mixtures with porous solid substances, a certain component or some components in the fluid can be sucked on the surface and concentrated on it, which is called adsorption.

3. RTO RCO is very effective in dealing with high concentration of VOC and odorous compounds, and its principle is to use excess air to burn these impurities, most of which generate carbon dioxide and water vapor, which can be discharged into the atmosphere.

4. Low-temperature plasma treatment equipment for industrial organic waste gas Plasma is a gas in an ionized state, commonly used such as: organic waste gas adsorption-desorption-condensation technology, adsorption concentration + catalytic oxidation technology and so on.

Combustion, adsorption, absorption, biological, low-temperature plasma, UV photocatalytic oxidation, **,

According to the difference in the working principle, the exhaust gas equipment can be classified into four types:

The first is exhaust gas treatment and absorption equipment. It is mainly the use of some solutions that are not easy to volatilize the exhaust gas to absorb and separate the working method, for this equipment can be reused, so it has the function of environmental protection.

The second is waste gas treatment adsorption equipment. It is mainly the process of using porous substances to adsorb the exhaust gas and make it fall off, and its operation process can be operated repeatedly, so its effect of purifying the exhaust gas is more obvious.

The third is the oxidation catalytic equipment for waste gas treatment. This method mainly uses the redox reaction of these waste gases, and finally generates water and carbon dioxide, ozone oxidation treatment process belongs to this category, its principle is to use the ozone generator to produce a sufficient amount of ozone (extremely oxidizing) injected into the reaction chamber to react with the waste gas molecules, and finally produce harmless and odorless substances discharged.

The fourth is the low-temperature plasma equipment for waste gas treatment. It is mainly used in the process of separating exhaust gases in a low-temperature environment.

Waste gas treatment equipment is divided into:

Filtration equipment: such as: bag filter, filter cartridge dust collector, plastic sintered plate dust collector.

Adsorption equipment: activated carbon adsorption, catalytic combustion.

Pyrolysis: UV photo-oxygen, plasma, catalytic combustion equipment.

Wet type: spray tower, deacidification tower. Whirlpool Tower.

Centrifugal force: cyclone dust collector.

There are 5 categories of waste gas treatment equipment, please add if they are incomplete.

If you are looking for waste gas treatment, I recommend finding a manufacturer with rich professional experience, because this can reduce your time and cost, and can give you a lot of suggestions on how to solve the waste gas and meet the emission standards.

At present, the state control environment is quite strict, and fines of hundreds of thousands or millions are imposed at every turn, so environmental issues are extremely important.

Personal suggestion: In this regard, I suggest you look for manufacturers in the Kunshan area, Aunason Environmental Protection Company focuses on waste gas treatment and provides one-stop solutions, you can consider it.

At present, the more advanced waste gas treatment equipment personally recommends the treatment method of nano micro bubbles, the treatment effect is good, the safety factor is high, there is no need for daily maintenance, and it is very energy-saving, after all, I am using it now, so the effect is very good, and some other methods are as follows.

Adsorption and catalytic combustion method: this method uses honeycomb activated carbon adsorption, and introduces hot air for desorption and analysis after the activated carbon is close to drinking, and the exhaust gas is introduced into the catalytic combustion bed after desorption to be burned without flame to purify it, but the disadvantage of this is that the equipment and pipeline are easy to be destroyed by high temperature, the service life is short, the energy consumption is large and the energy is not energy-saving, the pressure changes greatly, and the maintenance cost is high.

Direct combustion method: using oil or natural gas as auxiliary fuel combustion heating mixture heated to a certain temperature (700 -800), time to stop some, harmful gases produced by fuel combustion. The process of this method is simple, the equipment investment is low, but the energy consumption is high, the operating cost is high, the maintenance is difficult, and there are potential safety hazards.

Activated carbon adsorption method: direct adsorption of organic gases through activated carbon, simple equipment, small investment, easy operation, but need to replace activated carbon frequently. The wind resistance of the equipment is large, the wind pressure of the fan is high, and the power consumption is large.

Spray tower, activated carbon adsorption tower, catalytic combustion equipment, this is a common Wanchuan environmental protection waste gas treatment equipment, corresponding to different waste gas needs to use a variety of processes for treatment.

This year and 2020, the commonly used waste gas treatment equipment includes Wanchuan environmental protection CO catalytic combustion equipment, activated carbon adsorption tower, spray tower and so on. Why not use UV photolysis purifiers in 2020? Because the UV photolysis purifier will produce ozone, although the exhaust gas is treated, ozone is generated, and UV photolysis has been eliminated in Guangdong, and now CO catalytic combustion equipment is used.

Manufacturing: such as furniture factories, pharmaceutical factories, shoe factories.

Oil refineries, chemical plants, steel plants, automobile plants.

No, now it is a general trend of global environmental protection, and now extreme weather around the world is related to pollution, and the greenhouse effect is related to the emission of organic waste gases, which will destroy the ozone layer, so that we will receive more ultraviolet rays, so the greenhouse effect is formed. How is organic waste gas produced? What are the hazards of organic waste gas?

So how to deal with organic waste gas? The vast majority of organic waste gas is generated by some paint factories, paint factories and chemical plants, mainly alkanes, alcohols and ketones. How to deal with organic waste gas?

About 85% of enterprises across the country do not have waste gas treatment equipment, and organic waste gas is directly emitted. 10% of the enterprises have thermal incinerators, and the rest have other organic waste gas treatment equipment. More than half of the companies that own equipment do not use it frequently because of the high cost of equipment maintenance.

When the concentration of organic waste gas is too high, it is easy to poison people, such as headache, dizziness, cough, nausea, etc. In severe cases, poisoning of various organs of the body, organ failure, and may be life-threatening. Today, Wanchuan Environmental Protection recommends UV photolysis waste gas treatment equipment for everyone, which has stable performance, high efficiency, light weight, small footprint, and is a necessary equipment for all enterprises.

Plasma waste gas treatment equipment

The main principle is to release ozone by generating a strong electromagnetic field, so as to decompose odorous gases and achieve good effects of deodorization and oil smoke.

Biological deodorization towers

Also known as biological trickling filter tower, it is a process of absorbing odorous gases, such as sulfide gas, ammonia and other waste gases, and releasing carbon dioxide and water through the cultivation of biological bacteria.

Pulse dust removal equipment

It is divided into dry dust removal and wet dust removal, the dry dust collector is mainly for dry dust, using the principle of electromagnetic field, so that the dust is rotated and thrown out under the action of gravity, and then formed into ash at the bottom of the equipment tower, and then cleaned by mechanical vibration. Wet dust removal equipment, also known as wet electric dust removal, is mainly aimed at wet dust, fine particles, and some odorous bubble dust to clean, and uses spray cleaning to make the dust treatment cleaner and no secondary pollution.

Catalytic combustion equipment

Also known as RCO, the equipment has adsorption and desorption, heat storage, purging, release of heat energy, repeated operation, through the role of catalyst, the general temperature is between 300 -500, so that the exhaust gas is flameless combustion at low temperature, so that the exhaust gas treatment is more complete.
