Multi-stage cyclone dehydration device

Abstract

The invention relates to a multi-stage cyclone dehydration device which comprises a barrel, an air inlet formed in the side wall of the barrel, an air outlet formed in the top of the barrel, a water outlet formed in the bottom of the barrel, a core tube arranged in the barrel and a curved baffle plate surrounding the periphery of the core tube, wherein the curved baffle plate limits a spiral flow channel surrounding the outside of the core tube in an upper area in the barrel, and limits a liquid collecting cavity in a lower area in the barrel; the spiral flow channel is connected with the air inlet; the core tube is connected with the air outlet; the liquid collecting cavity is connected with the water outlet; and when a gas carrying a liquid enters the inside of the spiral flow channel from the air inlet, the gas rotates and enters the liquid collecting cavity under the action of the spiral flow channel, the liquid is separated from the gas under the action of centrifugal force and flows outside through the water outlet, and the gas enters the core tube and flows outside from the air outlet. The multi-stage cyclone dehydration device is capable of carrying out efficient dehydration on the gas carrying the liquid in a wet dust removal system, and is low in resistance and high in dust removal efficiency.

Description

technical field [0001] The invention relates to a dehydration device, in particular to a multistage cyclone dehydration device capable of separating water and air in a wet dust removal system. Background technique [0002] Wet purification systems such as converter primary flue gas wet purification system and wet desulfurization system must undergo dehydration treatment before the tail gas is discharged. The main function is to separate the water vapor attached to the dust from the flue gas for effective dehydration, thereby To improve purification efficiency, the second is to reduce water vapor emissions and waste of water resources. At present, dehydration mainly adopts the method of damping dehydration by using fillers or large-space settlement dehydration. Among them, the first method has relatively large resistance, and the maintenance workload and cost are large. The second method has huge equipment, occupies a large area, and requires a large investment. The dehydrat...
