A water curtain dust collector is an advanced environmental equipment for cleaning polluted air. It can suck air-containing mist or paint mist and has the air go through the water curtain and boiling mixing channel. The process is followed by separation and precipitation. This advanced equipment eliminates harmful paint mist and dust particles.

This is important to provide the operators with a clean working environment. Besides eliminating dust from the environment, such advanced equipment also plays an important role in the purification of air. Doubtlessly, they can improve the quality of air by using advanced filters to separate matter and release clean and healthy air into the environment.

It works by using a curtain of water to intercept and capture dust particles from the air stream. Interested to know more about its working? Well, read below!

How Does the Water Curtain Dust Collector Work?

A water curtain dust collector works in the following ways:

The entire working process starts with the help of the intake duct. Dusty air is drawn into the dust collector with the help of the intake duct. The method of drawing the air can be done via blowers or fans. They create a negative pressure to pull out the contaminated air into the system. After the dust-laden air intake process is finalized, a water curtain will form. How? Let’s read!

Water is sprayed inside the dust collector or allowed to flow down the surface. Doing this forms a continuous sheet or curtain of water. This sheet or curtain of water acts as a barrier through which the dusty air must pass. The water curtain can be created in the following ways:

1.Waterfall effect: In this effect, water flows over a series or surface of baffles in order to create a falling sheet of water.

2.Spray nozzles: In this process, fine droplets of water are sprayed in the form of a mist or sheet of water.

Once the water curtain is formed, the process of dust-capturing begins. As the dust-filled air passes through the water curtain, the particles collide with the water droplets. The following process occurs during dust capturing:

1.Diffusion: In this process, particles of fine size collide with water molecules due to Brownian motion. And ultimately, dust particles are captured.

2.Impaction: In this process, dust particles of larger size directly impact the water droplets. In this way, the dust particles are trapped.

3.Interception: Lastly, dust can be captured in a water curtain dust collector via interception. In this process, smaller particles are caught by the droplets of water as the air stream changes direction around them.

The combined effect of diffusion, impaction, and interception results in high capture efficiency for a wide range of particle sizes.

Once dust is captured, the process of dust and water separation begins. When the air passes through the curtain of water, the dust particles are suspended in the water. This dust-laden water falls into a collection tank or basin at the bottom of the dust collector. After passing through the dust collector outlet, clean air is achieved. The achieved clean air can also be vented back into the atmosphere or recirculated into the facility.

But what happened to the collected water?

The collected water, now loaded with tons of dust particles, passes through a thorough treatment before it can be used again. The step in water recirculation and filtration involves the following:

1.Sedimentation: In this process, dust particles of heavy size are allowed to settle at the bottom of the basin, and cleaned water is collected.

2.Chemical treatment: If necessary, the water can be filtered via chemical treatment. The user can add specific chemicals to aid in coagulation and remove fine particles. Or chemicals can also be added to neutralize the harmful chemicals.

3.Filtration: As the name suggests, dust containing water is filtered in this process.

The water loaded with dust particles can be cleaned using the above three methods. Once cleaned water is achieved, it is then pumped back into the water curtain dust collector and can be used to form a water curtain. The process is repeated, and the water is recycled in the dust-removing process.

What are the Key Components of a Water Curtain Dust Collector?

A water curtain dust collector is made up of several important parts. Malfunctioning of any part can result in faulty working or complete shutdown of the machine. Some key components of a water curtain dust collector and their function are listed hereunder:

1.Inlet and outlet dust: They are used to enter and exit the air stream.

2.Blowers/ Fans: They are important to create the necessary airflow throughout the work.

3.Waterfall surface of water nozzles: Such nozzles are important to generate the curtain or mist of water.

4.Collecting tank/Basin: It is used for capturing and settling out the water that is loaded with dust.

5.Pumps: It is used for recirculating or pumping the clean water.

6.Filtration system: It is used to clean dirty water and prepare it for reuse.

What are the Advantages of a Water Curtain Dust Collector?

Water curtain dust collectors are advanced equipment that is important for any factory or warehouse where there is air pollution. No doubt, pure and clean air, free from dust particles, is important both for workers and machines. The water curtain dust collector should be highly efficient in order to remove minute quantities of dust particles from the air.

Some advantages of water curtain dust collector are listed hereunder:

1.They are highly effective machines in capturing a variety of dust particles that are present in air. Either the particles  are  larger size, medium or small-size, an efficient water curtain dust collector can eradicate them easily.

2.They are best for reducing the risk of explosion and fire. If you own a combustible industry or if machines in your industry release certain combustible particles that can lead to an explosion, then installing a water curtain dust collector would be a great decision.

3.The water curtain in this  advanced machine is useful in creating a cooling effect. If you own or work in an industry in which there is excessive heat, then you should get a water curtain dust collector as soon as possible. It will bring a cooling sensation in the air.

4.Last but not least, in addition to providing a cooling effect, such machines also play an important role in air humidification. The water curtain can add sufficient humidity to the air. If you want to add humidity to your working environment, then a water curtain dust collector is the best option for you. Besides eliminating dust, it can also provide cooling as well as a humidification effect.

5.Water curtain dust collectors are highly effective and can work non-stop for hours. They can work non-stop and can provide you with clean air and a cool working environment as long as they are well-maintained and proper water supply is provided to them

6.Lastly, they are highly effective for hygroscopic and sticky dust particles. The water can easily clean these types of dust particles.

Where Are the Applications of Water Curtain Dust Collector?

No doubt, a highly efficient water curtain dust collector can be used in many places. They can be installed in any industry where there is air pollution, and the motive is to clean the air from dust particles. Some applications of water curtain dust collectors are listed hereunder:

Metalworking Industry:

It is used in the metalworking industry for capturing dust particles that are produced during polishing and grinding processes. Besides that, they can also be employed in industries where there is excessive cutting and welding work.
