Description
[ field of technology ]
The utility model relates to the technical field of wet type washing towers, in particular to the technical field of a trough type liquid distributor.
[ background Art ]
Wet scrubbers are a mechanical system that can remove contaminants from a gas stream by contacting them with a scrubbing liquid (most commonly water). Wet scrubbers are typically the only air pollution control devices that can remove particulates and gases/vapors simultaneously. They are very efficient at capturing the smallest dust particles and they can be captured in droplets, eliminating more than 99% of the airborne particulates. Wet scrubber towers, also known as absorbers, for removal of gaseous contaminants are widely used in industries ranging from acid, fertilizer and bitumen plants to steel plants and power plants. They provide alternatives to dust chambers and other dry dust collection methods. They are commonly used to control process plant off-gas and may also be located downstream of bag house/cartridge filter systems, furnaces, dryers, mixers, bucket lifts, bagging stations and other discharge points.
Wet scrubbers collect particulates and clean, cool, and absorb vapors and gases. They have a very high collection efficiency (99% for particles 5 microns or larger), low water consumption and minimal pressure drop. The scrubber has very strong anti-fouling capacity, with available capacities up to 200,000+cfm. Impingement plate (or tray) scrubbers use water flowing across porous surfaces. The gas stream is drawn into the scrubber and through the plate water. The water captures contaminants and removes them from the gas stream. Impingement plate systems typically use lower energy/lower pressure drop to scrub the gas. The impingement wash column is suitable for use in particle washing and applications where both particles and gaseous contaminants must be collected.
In a conventional wet scrubber system for flue gas purification, a wet scrubber is designed with a spray layer and a dehumidifying layer, the spray of the dehumidifying layer is conventionally designed by a spray pipe, the spray pipe is generally designed with 12-18 nozzles, the pressure behind the nozzles is 0.7bar, atomized liquid drops are 80um, and the following problems exist: 1. the spray pipe adopts a conical nozzle design, and has a large number of overlapped areas, so that excessive design of water quantity is caused; 2. the pressure of the spray nozzle of the spray pipe reaches 0.7bar, so that strong scouring is carried out on the wall and the support of the washing tower, the washing tower and the support adopt carbon steel and glass lining scales for corrosion prevention, scale falling is easy to cause, and corrosion phenomena are easy to occur on the washing tower and the support; 3. the atomized liquid drops 80um have larger pressure on the demister of the outlet section, which easily causes the increase of the moisture content in the flue gas.

Compared with the prior art, the water quantity overdose and the moisture content increase in the flue gas can be avoided, the scouring of the shell and the support of the washing tower is reduced, and the service life of the washing tower is prolonged.
