Embodiment Construction

[0030] Such as figure 1 As shown, the present invention uses the cobalt chloride solution to prepare the process method of steam utilization in the crystalline cobalt chloride process, at first the cobalt chloride solution is pumped into the liquid head tank before evaporation from the pre-evaporation liquid storage tank, and uses the first heat exchange The steam in the device preheats the cobalt chloride solution in the liquid head tank before evaporation to 60°C, then puts the preheated cobalt chloride solution into the evaporation kettle, and feeds steam to cool the cobalt chloride solution in the evaporation kettle. The solution is heated, the vacuum degree of the evaporator is -0.07MPa, and the temperature is 85°C. After the evaporation is completed, the remaining cobalt chloride solution is put into the crystallization kettle to carry out the crystallization process; the steam condensate used for heating the cobalt chloride solution is then Enter the second heat exchang...

Abstract

The invention relates to a steam application technological process in the process for preparing the crystal cobalt chloride by cobalt chloride solution. A first heat exchanger, a second heat exchanger, a set of triple heat exchanger composed of three heat exchangers and a vacuum cooling system are added in the prior process. The steam is utilized at maximum extent, the enterprise production cost is saved and the outfall steam pollution is decreased.

Description

technical field [0001] The invention relates to a process method for utilizing steam in the process of preparing crystalline cobalt chloride from a cobalt chloride solution. Background technique [0002] Evaporation is a commonly used method in the production of nickel-cobalt hydrometallurgy cobalt chloride, but the high-purity water produced in the process is not used and is directly discharged, resulting in waste of energy and environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a process for utilizing steam in the process of preparing crystalline cobalt chloride with cobalt chloride solution, which can save energy and reduce environmental pollution. [0004] The technical scheme adopted in the present invention is: [0005] The process method of steam utilization in the process of preparing crystalline cobalt chloride with cobalt chloride solution is characterized in that firstly, the cobalt chloride solution is ...
