Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone for treating flue gas in a power plant. Background Art

[0002] A cyclone is a separation and classification device that uses the principle of centrifugal sedimentation. Its core function is to separate and classify different substances by generating strong rotating shear turbulent motion in the fluid. When the fluid enters the cyclone tangentially from the periphery at a certain pressure, due to the difference in particle size or density between coarse particles and fine particles, they are subjected to different centrifugal forces, centripetal buoyancy and fluid drag.

[0003] Chinese patent CN205386378U proposes a gas-liquid cyclone capable of separating organic amine salt droplets in flue gas, including a flue gas primary gas distribution acceleration zone, an organic amine separation zone and a flue gas secondary gas distribution zone; the gas-liquid cyclone inlet is located in the flue gas primary gas distribution acceleration zone, and the gas-liquid cyclone outlet is located in the flue gas secondary gas distribution zone; the flue gas primary gas distribution acceleration zone is provided with several guide vanes; the organic amine separation zone is provided with one or more swirl blades; an air guide cap is provided above the gas-liquid cyclone outlet; the air guide cap is a conical structure. The utility model utilizes the cyclone separation principle to force the flue gas entering the gas-liquid cyclone to generate a swirl to form a centrifugal force, so that the organic amine salt droplets in the flue gas are separated from the flue gas under the action of the centrifugal force, thereby reducing the entrainment of the organic amine salt in the flue gas and reducing the loss of the organic amine. However, the above scheme requires bolts for connection, and the bolts are prone to rust after long-term use and are not easy to disassemble, making disassembly very troublesome, reducing the practicality of the cyclone for flue gas treatment in power plants.
