Description
Предложен способ дл обезвоживани растворов сульфата цинка.A method for dewatering zinc sulphate solutions has been proposed.
Известны способы обезвоживани растворов различных солей путем подачи их в нагретый псевдоожиженный (кип щий) слой, состо щий из твердых частиц, сквозь которые продувают гор чий газ.Methods are known for dehydrating solutions of various salts by feeding them into a heated fluidized bed (boiling bed) consisting of solid particles through which hot gas is blown.
Известные способы обезвоживани растворов сульфата цинка имеют р д недостатков.Known methods for dewatering zinc sulphate solutions have a number of disadvantages.
Предлагаемый способ обезвоживани растворов сульфата цинка состоит в том, что раствор при помощи форсунки распыл етс и подаетс на слой обезвоженного сульфата цинка, приведенного в псевдоожиженное состо ние, достигаемое продувкой сквозь этот слой с надлежащей скоростью топочных (гор чих) газов. Распыленный раствор, попада в слой, быстро обезвоживаетс благодар интенсивному процессу теплопередачи и испарению с образованием гранул сульфата цинка, размер которых регулируетс скоростью газов в слое.The proposed method of dehydrating zinc sulphate solutions is that the solution is sprayed using a nozzle and is applied to a layer of dehydrated zinc sulphate brought to a fluidized state, achieved by blowing through this layer at a proper rate of flue gases. The sprayed solution, falling into the layer, is quickly dehydrated due to the intensive process of heat transfer and evaporation with the formation of zinc sulphate granules, the size of which is regulated by the velocity of the gases in the layer.
Отличие предложенного способа от известного заключаетс в том, что кип щий слой состоит не из инертного материала, а из частиц сульфата цинка, раствор которого подлежит обезвоживанию. Кроме того, способ подачи раствора через форсунку, расположенную сверху над «кип щим слоем, и проведение процесса обезвоживани раствора осуществл ютс в одну стадию без возврата в слой вынесенного газами продукта. При этом достигаетс значительна интенсификаци процесса и высокий термический к. п. д. (80%) за счет снижени энергетических затрат, продукт получаетс в гранулированном виде повыщенного качества за счет меньщего содержани кристаллизационной воды.The difference between the proposed method and the known one is that the fluidized bed consists not of an inert material, but of particles of zinc sulfate, the solution of which is to be dewatered. In addition, the method of feeding the solution through a nozzle located above the "fluidized bed" and carrying out the process of dewatering the solution is carried out in one stage without returning the product carried by the gases to the layer. In this case, a significant intensification of the process and a high thermal efficiency (80%) due to a decrease in energy costs are achieved, the product is obtained in a granular form of enhanced quality due to a lower content of water of crystallization.
