Protecting the environment starts with details.
With the increasingly vigorous development of modern industry, a large amount of polluting waste gas will be produced during diversified industrial manufacturing and combustion processes. These waste gases will have a great harmful impact on the environment and human health. Therefore, these air pollutants must be controlled Under the control of environmental protection laws, these exhaust gases must be cleaned and neutralized pollutants before the gases can be discharged into the environment. For this purpose, we use acid-base fluids to neutralize the chemical components in the exhaust gas or remove particulate impurities. This process is called exhaust gas treatment or exhaust gas purification.
Exhaust Gas Treatment Equipment
Waste gas treatment equipment is a treatment equipment that can detoxify various harmful gases used in manufacturing projects and then discharge them safely. Depending on the type or amount of discharged gas, treatment methods include combustion, wet, dry, catalytic, etc. Most of the common waste gas treatment equipment today are waste gas scrubbing towers and activated carbon adsorption towers, which are widely used in industrial waste gas purification, dust removal, etc. to achieve the purpose of air purification.
Exhaust Gas Scrubber
The exhaust gas is processed in the scrubber to neutralize the acidity and alkalinity of the gas and remove particulate pollutants in the exhaust gas.
Activated Carbon Adsorption Tower
The pores of activated carbon materials are used to absorb gases containing odor components to achieve the purpose of eliminating odors.
Since the exhaust gas scrubber is currently the most widely used, its operating principle is introduced below.
Application Principle of Exhaust Gas Scrubber
A scrubber is a gas purification treatment equipment.
Common exhaust gas scrubber styles are: filled type, spray type, plate absorption type, and the most widely used of the above scrubber styles is the packed scrubber, which is suitable for high-efficiency operating environments, such as semiconductor and optoelectronic manufacturing plants, etc.
The bottom of the packed washing tower is a circulating water tank. There is an air inlet above the water tank. There is a washing liquid inlet connected to the nozzle at the top of the tower. There is a section of inert solid filling in the tower. The filling has a large area for liquid Contact with gas. The exhaust gas is transported from the inlet at the bottom of the scrubber tower to the tower body by a fan, and the scrubbing liquid with added chemicals is sprayed down from the top of the tower in the form of mist or droplets. It flows in the opposite direction through the gaps in the filler and the sprayed liquid, causing the gas to flow in the opposite direction. It fully contacts with the liquid and carries out chemical reactions, adsorbing the acidic or alkaline pollutants contained in the gas to the washing liquid, allowing the acid and alkali of the gas to neutralize and the pollutant compounds to precipitate in the circulating water, and then the purified gas is It is separated from the contaminated liquid and leaves the scrubber after being treated by the demister layer. It enters the fan and is discharged upward from the chimney into the atmosphere to produce a scrubbing effect. After washing, the waste liquid is collected in the circulation tank at the bottom of the tower and then discharged to the wastewater system for treatment.
Application of Sealless Magnetic Pump in Scrubber
In the scrubber equipment system, the pump is also an indispensable member. The washing liquid mentioned in the above application principle must be transported to the top of the tower through a pump, and through the nozzle, the washing liquid containing chemical substances is sprayed down from the top of the tower in a mist form. After the exhaust gas is purified, the final liquid flows to the circulation tank at the bottom of the tower. Part of the liquid needs to be pumped into the scrubber again to continue the process of circulation and neutralization; the other part is to discharge the contaminated liquid to the sewage treatment plant.
Among them, since the washing liquid contains acidic and alkaline chemicals, "corrosion resistance" has naturally become one of the essential elements of the circulation pump. This part is quite suitable for the use of sealless magnetic pumps, which can effectively prevent the danger caused by chemical liquid leakage.
