If you are looking for pollution control devices then you should know about wet scrubbers. Wet scrubbers are used to remove the particulates matters from gas and liquid streams. A wet scrubber is that scrubber which gets rid of pollutants from gas streams or from furnace flue gas. The polluted stream of gas comes in contact with that scrubbing liquid to get rid of pollutants. The design of the wet scrubber relies on industrial condition involved, the nature of air pollutants. With the help of scrubbers, it is possible to remove gaseous pollutants and collect particulates. Wet scrubbers are really versatile dust-control systems that may be built in several configurations. The main purpose of using wet scrubber is to establish contact between polluted gas and the liquid.
Wet Scrubbers are really efficient dust control systems that help in the elimination of dust particles from gases and liquid droplets. Wet scrubbers are a great way to control air pollution, plant emissions in most of the situations. The system is meant to remove or scrub off contaminants from a stream of air with the help of a scrubbing solution or a scrubbing fluid. The design of the scrubber is dependent on the nature of pollutants to be removed and the industrial conditions. With the help of scrubbers, it is possible to remove both gaseous pollutants and particulate matter as well. It is such a versatile pollutant remover that it may be built in several configurations depending on the conditions. All the scrubbers serve the purpose of establishing contact between the polluted gas stream and the scrubbing liquid.
How It Removes Pollutants?
Wet scrubbers consist of scrubbing vessels, mist eliminator, exhaust stack, pumping, and ductwork. Wet scrubbers capture the polluted liquid droplets and then eliminate dust particles. After the droplets are collected, the liquid dissolves pollutants or absorb the polluted gases. The ability of the scrubber to collect the droplets or small particles is directly proportional to the output of power in the scrubber. The ones that remove gaseous pollutants are referred to as absorbers. In order to attain high removal efficiency, it is necessary to establish gas to liquid contact. You will mostly find wet scrubbers carrying plate tower and packed tower to remove gaseous pollutants. The solution is good when it comes to removing, cleaning or scrubbing contaminants from the stream of air. Some of the contaminants it might get rid of are dust particles, oils, mist, gas, and fumes. The pollutant-laden gas is mixed to the scrubber liquid to render it pollutant-free. The liquid here may be organic-based or water-based.
The Various Kinds Of Wet Scrubbers
So, you can understand how very valuable a wet scrubber is. As per the nature or property of pollutant, we have different kinds of scrubbers. Impingement plates can absorb gases and vapor to collect the particulates. It is best meant for applications that need the removal of particulate or needs condensing. Venturi is again used to collect liquid mists and very fine particulates. It may be used in highly corrosive situations. Depending on the nature of pollutants to be removed, the scrubber may be designed.
When You Should Use The Wet Scrubber?
You also need to remove pollutants from gases and liquids and for this reason you need a wet scrubber. A wet scrubber is the safest choice for the removal of combustible dust particles. Water is used as the collection medium to get rid of dust cloud by wetting the dust or by saturating an air stream. A wet scrubber is efficient enough to handle high-temperature application. There isn’t any requirement for frequent parts replacement or design consideration.
There are various benefits of using wet scrubbers for the removal of contaminants. The cost of maintenance and the initial capital cost is low. It offers an efficient and much better energy saving. You need not to use a replacement bag. The wet scrubber can easily handle excessive moisture and high temperature.
