Fixed bed ion exchange equipment

A typical fixed bed ion exchange equipment and process is shown in Figure 1. The figure shows the two-column adsorption and one-column rinsing process. That is, the I and II towers are adsorbed in series, and the III tower is rinsed. Of course, more towers can be adsorbed in series. Fixed bed ion exchange systems for the recovery of uranium began in the early 1950s. The first is success in South Africa. It was subsequently applied in countries such as Australia and Canada. By the end of the 1950s, there were more than 50 fixed bed ion exchange equipment in Canada alone for the treatment of clarified acid uranium leachate. Leachate uranium concentrations ranged from 0.6g to 1.0g U 3 O 8 ∕L, and some fixed bed ion exchange equipment were still in operation since the 1980s.

The disadvantages of the fixed bed ion exchange equipment are: due to the cyclic operation, the resin utilization rate is low; the flow rate is limited, the output is low; the resin bed remains stationary, so the bed resistance is large and the power consumption is large; usually, the multi-tower series operation, In some large uranium plants in South Africa, dozens of towers can be operated in series. Therefore, there are many valves, complicated pipelines, complicated control systems, many auxiliary facilities, large floor space, and inconvenient maintenance. If resin poisoning occurs, resin replacement is required. huge.

The advantage of the fixed bed ion exchange equipment is that the resin is in a static state during operation, the solution flows, and the service life of the resin can reach about 20 years.
