Embodiment Construction

[0039] A ring-added cyclone separator, such as figure 1As shown, a ring-added swirl plate separation device includes a swirl plate 5, a separation ring 4 fixed on the swirl plate 5, a constricted wall 2, a separation ring 4 and an annular cover 11 on the constricted wall 2, a flushing nozzle 3 , the lower cone 10, the middle cylinder 9 and the upper cone 8. The swirl plate 5 is composed of a plurality of swirl plate blades, which are welded and fixed between the middle cylinder 9 and the outer wall 6. The inclination angle of the swirl plate blades is designed between 45° and 60°, and the width of the blade overlapping area 12 is the same inside and outside. , the θ angle is about 5°-15°, and its upper boundary 14 can be horizontal or inclined, but all the points of the same radius on the blades are at the same height, which is convenient for welding and fixing the separation ring 4 and the lower boundary of the swirl plate 5 15 is inclined so as to guide the separated drople...

Abstract

The invention discloses a ring whirlwind plate separator. The ring whirlwind plate separator comprises a cylindrical outer wall of which the top end is provided with an outlet, an inner solid body vertically arranged in the outer wall, a whirlwind plate fixedly connected between the outer wall and the inner solid body, and a separation ring. The inner solid body is used for promoting air to flow close to the outer wall surface and accelerating a fluid flowing rate. The whirlwind plate is used for blocking particles and promoting air flow rotation. The separation ring is used for shortening a particle centrifugation motion distance. The separation ring is circularly fixed to the whirlwind plate. The ring whirlwind plate separator reduces critical separation particle sizes and can be designed in a low pressure drop scope.

Description

technical field [0001] The invention relates to a ring-added cyclone separator, which belongs to the technical field of material separation, and is especially suitable for gas-liquid separation in a flue gas wet purification project, in particular to a design principle of a ring-added cyclone separator structure Theoretical calculation process with quantitative design and the characteristics of material separation. Background technique [0002] The swirl plate separator uses swirl blades to make the gas rotate, and under the action of centrifugal force, the purpose of gas-liquid and gas-solid separation is achieved. Due to its simple structure and good separation efficiency, it is widely used in chemical industry, mining and metallurgy, food, medicine, electric power and environmental protection and other industries, such as gas-liquid separation in chemical production processes such as acrylonitrile and melamine, for smoke Demisting during air-wet purification and preheati...
