Cyclone plate tower
Thread Content
The swirl plate tower is an efficient and energy-saving device for mass transfer and absorption, suitable for processes such as rapid absorption, washing, demisting, and dust removal. Since its introduction in the 1970s, it has received widespread attention and application in industries such as environmental protection, petroleum, chemicals, light industry, and metallurgy. In recent years, it has been widely used in the field of flue gas dust removal in metal smelting and industrial waste gas treatment, generating significant social, environmental, and economic benefits.◎ Main features of the swirl plate tower:
① Excellent mass transfer and heat transfer performance;
② Good anti-clogging properties and ease of operation;
③ High gas-liquid load with minimal mist entrainment;
④ Low pressure drop across the tower plates and low system resistance;
⑤ Good dust removal and absorption capabilities, exceeding 98%.
◎ Working principle of the swirl plate tower: When in operation, gas enters the tower from the bottom at an angular velocity and rises spirally under the guidance of the blades on the tower plates. Liquid is distributed to each blade via blind plates, forming a thin film layer that is then sprayed by the gas stream into liquid droplets. These droplets move with the gas flow and are forced toward the tower wall by centrifugal force, forming a liquid ring that rotates along the wall. Under the influence of gravity, the liquid flows down along the wall to an annular collection tank, from where it moves to the next blind plate through an overflow mechanism. The liquid that flows down across the plates is sprayed by the gas into droplets, thereby creating a large contact area between the gas and liquid. The droplets rotate due to the gas flow, and the resulting centrifugal force enhances the contact between them. As the liquid is sprayed onto the gas in the swirl plates, dust particles attached to it are also thrown toward the tower wall and carried downstream. Thanks to the favorable gas-liquid contact conditions within the tower, acidic gases in the gas can also be absorbed by the alkaline liquid. The swirl plate tower thus also has demisting capabilities, which helps to extend the service life of fans.
