Problems solved by technology

[0002] Industrial materials and industrial wastewater are often treated by evaporative concentration process. When using the existing evaporative crystallization device to evaporatively crystallize the solution, due to the small heating area of ​​the solution, the evaporative crystallization speed is slow, resulting in time-consuming evaporation and crystallization process. longer
In addition, an evaporative crystallization device can usually only process one solution, which wastes resources and fails to improve the utilization rate of the evaporative crystallization device

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0017] like figure 1 and 2 An evaporation and crystallization device shown includes an evaporation chamber 1, a crystallization chamber 4 communicating with the evaporation chamber 1, a second pipe 3 placed in the evaporation chamber 1 and arranged radially outward, an inner cylinder 8 and a first pipe 2. High-temperature steam can be passed into the evaporation chamber 1 for heating, or the temperature inside the evaporation chamber 1 can be raised by other means.

[0018] The diameter of the first pipe 2 is 1.5-2 times, and p...

Abstract

The invention provides an evaporation and crystallization device. The evaporation and crystallization device comprises an evaporation chamber, a crystallization chamber which is communicated with the evaporation chamber, as well as a second pipeline, an inner cylinder and a first pipeline which are arranged in the evaporation chamber and sequentially arranged outwards in the radial direction; the first pipeline and the second pipeline are distributed spirally in the axial direction; the first pipeline and the second pipeline are respectively provided with an inlet branch pipe and an outlet branch pipe extending out of the evaporation chamber; and the crystallization chamber is communicated with the first pipeline and the second pipeline respectively through a pipeline. The first pipeline and the second pipeline which are distributed spirally in the axial direction are arranged in the evaporation chamber, so that the heating area of the solution is enlarged, the rate of evaporation and crystallization of the solution is raised, evaporation and crystallization treatment on two different solutions can be achieved, the versatility of the evaporation and crystallization device is improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of evaporation crystallization, in particular to an evaporation crystallization device. Background technique [0002] Industrial materials and industrial wastewater are often treated by evaporative concentration process. When using the existing evaporative crystallization device to evaporatively crystallize the solution, due to the small heating area of ​​the solution, the evaporative crystallization speed is slow, resulting in time-consuming evaporation and crystallization process. longer. In addition, an evaporative crystallization device can usually only process one kind of solution, which wastes resources and fails to improve the utilization rate of the evaporative crystallization device. [0003] In view of this, it is necessary to improve the evaporative crystallization device in the prior art to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to...
