Embodiment 1

[0033]Take the process of the present invention for treating the bittern water discharged from the saltworks as an example. When the amount of bittern is 50kg / h, the inner diameter of the atomized crystallization chamber 1 is designed to be 1.8m, and the height is 2.5m; the top rectifier 18 of the atomized crystallization chamber 1 has a diameter of 0.9m, and the cross section of the hot air pipe 2 connected with the rectifier 18 The size is 0.8×0.8m. A compensator 13 is set between the hot air pipe 2 and the external pipeline of the equipment to absorb the lateral, longitudinal and axial displacement caused by the high-frequency vibration of the vibration unit 11. The cross-sectional size of the compensator 13 is 1.0× 1.0m; the diameter of the high-speed centrifugal atomizer 14 is 0.225m, the power is 550W, the rotation speed is 2800rpm, the spray volume is adjustable from 0 to 50kg / h, and the diameter of the polytetrafluoroethylene stock solution pipeline 12 connected to the ...

Abstract

The invention discloses a vibration type atomized evaporative crystallization device. The vibration type atomized evaporative crystallization device comprises an atomized crystallization unit and a vibration unit, wherein the vibration unit comprise a rack, a motor and an eccentric gear which are located inside the rack; the motor is connected with the rack through a support; the motor is connected with the eccentric gear below the motor through a transmission shaft; the eccentric gear is arranged on a vibrating plate; the vibrating plate is connected with a torsion bar through a vibration bearing; a retainer of the vibration bearing is fixed on the rack; the other end of the torsion bar is connected with the atomized crystallization unit; an atomized crystallization chamber serves as the main body of the atomized crystallization unit; a hot air pipe and a high-speed centrifugal atomizer which is connected with a stock solution pipeline are respectively arranged at the top end of the atomized crystallization chamber; an air return pipeline is connected to the bottom end of the atomized crystallization chamber; a rectifier is arranged at the upper part of the atomized crystallization chamber. The vibration type atomized evaporative crystallization device, disclosed by the invention, has scale proofing and cleaning double functions, cancels the operation procedure that the conventional atomized evaporative crystallization device is required to be regularly shut down for scale cleaning, realizes continuous operation, and obviously improves the running efficiency of the device and the collecting yield of the crystallized product.

Description

technical field [0001] The invention belongs to the field of chemical crystallization separation, and in particular relates to a chemical industry crystallization separation device. Background technique [0002] The atomization evaporation crystallizer is widely used in the chemical production process to accelerate liquid crystallization and solid-state drying. It is suitable for the production of powdery and granular solid products from high-concentration solutions, emulsions, suspensions and pasty liquids. When the particle shape, size distribution, water content and bulk density have strict standards, atomization evaporation crystallization is a very ideal process. At present, the working form of most atomization evaporation crystallizers is: the air is filtered and heated, enters the air distributor on the top of the equipment, and the hot air enters the crystallization chamber evenly in a spiral shape. The liquid raw material is atomized into extremely fine droplets by...
