Anti-scaling sufficient mixing reaction kettle capable of continuously reacting

Abstract

The invention discloses an anti-scaling sufficient mixing reaction kettle capable of continuously reacting. The feed method of the material is changed, the tangential feeding is adopted, feeding components are distributed in the two directions of a reactor, the wall of the reaction kettle and a heating tube are continuously flushed, the feeding temperature is the lowest, the feeding components arebe in direct contact with the heating surface, the heating effect is improved, the temperature of the material in the reaction kettle is much closer to the reaction temperature, the reaction efficiency is improved, various kinds of mixing blades are combined, so that the material does not move in a certain way in the reaction kettle and forms disordered motion, the centrifugal effect is reduced,the particle material or large-gravity material is prevented from being in contact with the heating surface for a long period of time, the scaling of the material is avoided; meanwhile, the mixing ismore sufficient, the reaction efficiency is improved, the scaling is reduced by more than 90% by using the equipment provided by the invention, the temperature is accurately controlled, the material is mixed evenly, and the reaction rate is increased by 5%.

Description

technical field [0001] The invention relates to an anti-scaling and fully mixed continuous reaction reactor, which belongs to the technical field of reactor equipment. Background technique [0002] At present, the commonly used reactor stirring methods are blade type and paddle blade type; in the case of rotating stirring, the material will be turned up and down and under the action of centrifugal force, the material will be centrifugally separated, so that the centrifugation of the heavy gravity will be closer to the wall of the reactor; and The reactor is heated through the inner coil of the reactor wall or the abdominal wall, so that the material with high gravity is easy to contact the high-temperature heating surface for a long time. Especially when the liquid reacts with the powdery material and the material with high gravity is easy to scale, the reaction kettle is more likely to scale. Due to uneven mixing, the reaction effect is poor and the yield is low. [0003] ...

[0002] At present, the commonly used reactor stirring methods are blade type and paddle blade type; in the case of rotating stirring, the material will be turned up and down and under the action of centrifugal force, the material will be centrifugally separated, so that the centrifugation of the heavy gravity will be closer to the wall of the reactor; and The reaction kettle is heated through the inner coil of the reaction kettle wall or the abdominal wall, so that the material with high gravity is easy to contact the high-temperature heating surface for a long time

Especially when the liquid reacts with the powdery material and the material with high gravity is easy to scale, the reaction kettle is more likely to scale. Due to uneven mixing, the reaction effect is poor and the yield is low.
