Background
In the hydrometallurgy process, a heat exchanger (heat exchanger) is needed to heat various solutions so as to achieve various technical indexes of improving leaching rate, recovery rate and the like, and the filtering process can normally operate only by increasing the temperature of the solution. In the hydrometallurgy process, two main types of direct heating and indirect heating are adopted. The direct heating can be realized by adding steam into the solution, but a large amount of steam condensate water enters the process, so that the condensate water cannot be recycled, and the process is expanded in volume and cannot run. Many workshop sections can only select to adopt heat exchanger (heat exchanger) to carry out indirect heating, can divide into tubular heat exchanger and plate heat exchanger according to the shape and the structure of heat transfer surface, heats solution as the heat source with steam, indirect heating's biggest drawback: the cleaning is quite difficult when the catalyst is used under the condition of easy crystallization. Meanwhile, as the heat exchanger tube plate is eroded by water, cavitation and trace chemical media, leakage often occurs at the welding seam of the tube plate, so that water and chemical materials are mixed, the temperature of the production process is difficult to control, other products are generated, the quality of the products is seriously influenced, and the grade of the products is reduced.
