1. The principle of forced circulation is to use high speed and large flow to achieve a uniform distribution of liquid concentration in the electrolytic cell; natural circulation is to use a unique internal structure and the bubbles generated by the electrolysis process to achieve a uniform distribution of liquid concentration in the electrolytic cell. 2. The advantage of forced circulation is mainly the uniformity of concentration distribution. The disadvantage is that a large pressure difference is used to control the pressure difference between chlorine and hydrogen, which easily causes vibration of the ion membrane and has a certain impact on the service life of the ion membrane. The main advantages of natural circulation are that it can also meet the needs of uniform liquid distribution; it also saves a lot of equipment and power consumption; it is smaller than forced circulation in controlling the pressure difference between chlorine and hydrogen, further reducing the vibration of the membrane and extending the service life of the ion membrane. 3. Natural circulation is the mainstream direction of the development of ion membrane electrolyzers.
Thank you very much for the answer above, very accurate!
Therefore, the concentration of anolyte in different processes is different, which is to consider the distribution of concentration.: The membrane can accept 170g/l, but every point must be met. To ensure this, the control indicators of different processes are different. If not, please correct me. :handshake This post was last edited by limingshuguang on 2007-12-10 10:28 ]
But there is some natural circulation that seriously corrodes the coating of the tank frame.
