Industrial sewage cooling recrystallization recycling device

Abstract

The invention discloses an industrial sewage cooling recrystallization recovery device, which comprises a support installation module, a spiral cooling crystallization module and a crystallization filter unloading module. The support installation module includes a support installation plate, and the left and right ends of the support installation plate are symmetrically arranged with The support column, the top of the support mounting plate is vertically provided with a crystallization installation cylinder, the spiral cooling crystallization module is installed in the crystallization installation cylinder, the spiral cooling crystallization module includes spiral cooling pipes in the crystallization installation cylinder, and the crystallization filter unloading module It is embedded in the support installation plate, and the crystallization filter unloading module includes a variable-diameter collection tank installed on the lower end of the crystal installation cylinder and inlaid on the upper end of the support installation plate. The present invention has novel and compact structure, high cooling and crystallization efficiency, and a coherent crystallization process. , It has the advantages of fast and convenient crystallization.

Description

technical field [0001] The invention relates to an industrial sewage treatment device, in particular to an industrial sewage cooling recrystallization recovery device. Background technique [0002] There are many reusable inorganic salts in industrial sewage, which contain many precious elements, but the traditional industrial sewage recrystallization device is not perfect in design, resulting in less crystallization and slow crystallization speed. The serious aging of components and the difficulty of crystallization seriously restrict its development and utilization. [0003] In order to solve the above problems, the present invention is proposed, which avoids the direct injection of cold water for cooling and crystallization, resulting in a decrease in the concentration of industrial sewage and a decrease in crystallization efficiency, and avoids the traditional cooling pipe directly contacting industrial sewage, resulting in crystallization on the surface of the pipe, res...

Problems solved by technology

[0002] There are many reusable inorganic salts in industrial sewage, which contain many precious elements, but the traditional industrial sewage recrystallization device is not perfect in design, resulting in less crystallization and slow crystallization speed

The aging of the components is serious, and it is difficult to obtain crystallization, which seriously restricts its development and utilization

[0003] In order to solve the above problems, the present invention is proposed, which avoids the direct injection of cold water for cooling and crystallization, resulting in a decrease in the concentration of industrial sewage and a decrease in crystallization efficiency, and avoids the traditional cooling pipe directly contacting industrial sewage, resulting in crystallization on the surface of the pipe, resulting in a decline in cooling effect It solves the problem of the traditional industrial sewage treatment device. Because the collection of crystals needs to be dumped and filtered, or the crystals are fished, the crystallization process is broken, the program is disordered, and the crystallization operation with less overflowing liquid is carried out, so that the present invention has a novel and compact structure, cooling and crystallization High efficiency, coherent crystallization process, fast and convenient crystallization, etc.
