Water Spray Dust Removal_Other Equipment_Products

TONY Water Spray Dust Removal is a kind of water film caused by a certain method on the inner wall of the dust collector or other special components, so that the dust is captured by the water film and the gas is purified, which belongs to a kind of wet dust collector.

Spray Dust Removal equipment: A purification device that uses dust-containing gas to impact the inner wall of the dust collector or other special components to form a water film in a certain way, so that the dust is captured by the water film and the gas is purified. It includes impact water film, inert (shutter) water film and centrifugalwater spray dust removals.

In the treatment of industrial waste gas, the spray tower sucks the collected waste gas into the washing tower through a fan unit, flows through the filling layer section (the medium for gas/liquid contact reaction), and allows the waste gas to fully contact the liquid (washing solution) flowing on the surface of the filling material to adsorb acidic or alkaline pollutants contained in the waste gas. Then, the clean gas is separated from the contaminated liquid to achieve the purpose of purifying the air.

The working principle of the Water Spray Dust Removal is to separate fly ash by using the centrifugal separation principle and the flushing, wetting and adsorption of water. ‌

The dust-laden gas is introduced tangentially from the lower part of the cylinder, and rotates upward. The dust particles are separated by the centrifugal force and thrown to the inner wall of the cylinder. They are adsorbed by the water film layer flowing on the inner wall of the cylinder, flow to the bottom cone with the water, and are discharged through the dust discharge port. The water film layer is formed by several nozzles arranged on the upper part of the cylinder, spraying water tangentially to the wall of the device, so that the inner wall of the cylinder is always covered with a thin water film that rotates downward, so as to improve the dust removal effect.

In summary,Water Spray Dust Removal has excellent performance in industrial applications due to its advantages of high efficiency dust removal, simple structure, low price, high temperature resistance and reduced dust pollution.

1. Air Intake And Preliminary Separation

The dust-containing gas enters the water film dust collector through the intake pipe. At the initial stage of air intake, due to the change in the direction of gas flow and the decrease in speed, some of the larger dust particles are preliminarily separated from the gas under the action of inertial force and gravity, and then settle to the bottom of the dust collector. This stage is similar to simple gravitational settling dust removal, which only preliminarily removes the larger dust particles that are easier to separate, preparing for the subsequent fine dust removal.

2. Formation Of Water Film And Dust Capture

Inside the dust collector, one or more nozzles spray water onto the inner wall of the collector, and the water flows down along the wall, forming a continuous water film. When the dust-containing gas passes through, the dust particles in the gas come into contact with the water film.

For small dust particles, due to the surface tension and viscosity of water, the dust particles will be adsorbed by the water film. This process is like the dust being "stuck" by the water, and the water film acts like a sticky filter screen, preventing the dust from continuing to flow with the gas.

Meanwhile, when the dust-containing gas passes through the water film, collisions, diffusions and other effects will also occur. Some dust particles will lose their kinetic energy due to collisions with water molecules in the water film and then be captured by the water film; some other dust particles will have more opportunities to come into contact with the water film due to the turbulent diffusion of the gas, thus increasing the probability of being captured.

3. Dust Settling And Drainage

The dust captured by the water film flows downwards along with the water flow and finally converges into the water collection tank at the bottom of the dust collector. In the water collection tank, the dust is separated from the water, with the dust settling at the bottom and the water being able to be reused after being processed by the circulating water system. The circulating water system will perform operations such as filtering and purifying the water to ensure the quality of the water film and the dust removal effect.

During the drainage process, in order to prevent the dust from being raised again, the drainage outlet is usually set at a lower position, and the water flow speed is moderate to ensure that the dust can stably settle at the bottom.

4. Discharge Of Purified Gas

The purified gas after water film dust removal continues to flow upwards and is discharged from the dust collector through the exhaust pipe. At this time, the dust content in the discharged gas is greatly reduced, achieving the purpose of purification. During the whole process, the direction of gas flow and the direction of water film flow cooperate with each other to ensure that the dust can be captured by the water film to the greatest extent, thus realizing efficient dust removal.

Water Spray Dust Removal is suitable for working conditions with a large number of particles such as smoke and dust, such as sintering machines, boilers, electric furnaces, metallurgy, chemical industry, cement and other industries. In addition, Water Spray Dust Removal is also widely used in commercial buildings, urban gas purification and other fields.

Water Spray Dust Removal is suitable for capturing fine, dry, non-fibrous dust, especially for treating high temperature, high humidity and high viscosity dust. During the treatment process, water spray dust removal sends the exhaust gas into the water film through the spray system, so that the gas contacts the water film, and uses the blocking and inertia of the liquid film to intercept the particles on the surface of the water film, which are then washed away. The cleaned water is recycled and reused to achieve green environmental protection.

It should be noted that when using Water Spray Dust Removal, the thickness and flow rate of the water film need to be controlled to avoid blockage. At the same time, the Water Spray Dust Removal equipment needs to be cleaned and inspected regularly to maintain its normal operation. The water used by the Water Spray Dust Removal needs to be treated and recycled to prevent waste and pollution.

In general, Water Spray Dust Removal is an environmentally friendly and efficient dust removal process with a wide range of applications.
