Water Curtain Dust Collector
Water-based dust collectors use atomizing nozzles and a collection booth to suppress dust and debris from industrial stoneworking applications. These systems typically incorporate onsite wastewater treatment and recirculation to minimize water consumption and waste disposal.
The swirling curtain dust collector has a deduster box body, distribution of air flow pipe, spoon-shaped curved surface plate and gas, liquid separator arranged on top. It is characterized in that a flue gas flow-guiding channel (7) is formed with its top and the clean room (6).
Dust Suppression
When fine dust particles come into contact with water, they are weighed down and become grounded. This prevents them from becoming airborne and helps to reduce the amount of fugitive dust in the air. However, spraying water isn’t always the best method for controlling dust. It isn’t effective at removing all dust and it can be counterproductive to the dust suppression process by creating an additional energy source, which could make the particles fly up into the air.
Another solution is to use a swirling curtain to contain dust. This system uses a combination of mechanisms, including collision, interception and diffusion to gather fine dust into a mixture of dust and water, which can then be removed by cyclone centrifugal separation. This type of system is ideal for transferring large amounts of material in a closed area and it also offers an attractive price point for mining applications.
In addition, this technology can also be used to clean the surface of a machine or conveyor. This is achieved by injecting water into the system. This water then comes into contact with the dusty surface and scrubbing it away, which can improve the appearance of the equipment and make the entire plant more appealing. This also helps to keep the work environment safer for employees by reducing the amount of dust in the air.
Dust Elimination
Wet dust control systems use water or a specialized liquid solution to trap contaminants and keep them from recirculating in the workplace. They feature spray nozzles or venturi scrubbers that inject water into the airstream, creating a dense curtain of mist that captures dust particles. The moisture increases the cohesive force between dust particles, making them more difficult to move and allowing the finer ones to penetrate the surface of the water droplets and become entrapped. The contaminated water is separated from the clean airstream and collected as wastewater, which is then disposed of in accordance with local environmental regulations.
A swirling curtain dust collector uses ultrasonic atomizer and pressure sprayer to produce water curtain dust collector a water curtain that combines three mechanisms of collision, interception and diffusion. The water and dust mixture gathers into the wall of the cyclone, where it is removed under the action of centrifugal force.
Because they eliminate the need for filter bags and cartridges, wet dust suppression systems reduce maintenance costs over time. They also extend the life of production equipment and help maintain a cleaner work environment. They are available in a variety of sizes and configurations to suit specific facility needs, including airflow capacity, dust loading and space constraints. Additionally, many feature automatic water level controls and overflow protection to minimize wastewater and ensure consistent performance.
Sludge Removal
A water curtain dust collector consists of two parts: the wet scrubbing section and the dry air separation section. The contaminated air enters the wet scrubbing section through fixed baffles. The centrifugal force caused by the rapid changes in the airflow direction forces the dust particles to penetrate the water droplets and become entrapped. The contaminated water is removed from the airstream by special mist filters. The remaining dust is captured as sludge and sinks to the bottom of the basin. The remaining water is reused.
The pulse controller of the prior art is all arranged inside the dust collector, which causes inconvenient maintenance for people when it is overhauled. The present invention provides a water curtain dust collector with a pulse controller that is separate from the main body of the dust collector.
The moisture carried in the clean air is eliminated through a carefully designed wide space “V” shaped demisting baffle or 3 curved baffles. Water in the basin is reused repeatedly after the water curtain generated by the air flow is formed, so that no water pump or nozzle is required. However, a small amount of fresh water is always added to the make-up joint in order to compensate for the water that is taken away during evaporation or sludge discharge. This allows the device to operate continuously 7 * 24 hours without shutdown for sludge discharge and water replenishment.
Energy Saving
A water curtain dust collector uses spray nozzles to saturate a section of the mine gallery with a curtain of water. The dust particles are dispersed or absorbed by the water, and the sludge is removed from the system using manual scraper or mechanical scraper conveyors. This method of dust suppression is ideal for hygroscopic or sticky dusts that would otherwise be difficult to remove with traditional dry scrubbers.
Using a wet dust collection system can also reduce energy consumption, since the dust particles are captured bimetal bandsaw blade manufacturers in the water curtain. This is a more efficient alternative to dry dust suppression, as the particles are not scattered by air movement, and there is no need for a blower.
The swirling curtain dust remover is an advanced atomization device which combines the advantages of swirling atomization and the water-spray curtain technology to improve the dedusting effect of longwall galleries. The device is mainly composed of a dust collector box, a bidirectional swirling-dedusting-dewatering machine and a spray device. The body of the dust collector box is divided into two cabinets: the first cabinet is a cleaning room, while the second cabinet has an air inlet. The dust collector box is supported by four landing legs. The air outlet of the first cabinet is connected to the spray device and the dust collecting chamber.
