Press filtration type diffusion dialysis apparatus

Abstract

The present invention provides a press filtration type diffusion dialysis apparatus which increases the number of recovery chambers and discharge chambers in a tank to increase the acid and alkali recovery capacity of each tank and prevent damage of the ion exchange membrane caused by the dilution heat. The filter filtration diffusion dialysis apparatus (100) has a configuration in which fastening frames are arranged at both ends of a fastener (20) in which two to ten stacks (5) are usually assembled. In each of the stacks (5), a film of 20 to 200 pairs and a frame of a frame are used, preferably 40 to 120 pairs of film and frame. By stacking a plurality of pairs of cells in the tank by stacking (5), it is possible to arrange a large number of film groups between the buffer frame (1) and the buffer frame (3), and the film area of each groove can be significantly increased. By constructing the stack in this manner, the maintenance performance is improved.

Description

technical field [0001] The present invention relates to a filter press type diffusion dialysis device, in particular to a method for increasing the number of recovery chambers and drainage chambers in a tank, so as to improve the recovery capacity of acid and alkali in each tank, and prevent the ionization caused by dilution heat. A press-type diffusion dialysis device with damage to the exchange membrane. Background technique [0002] At present, the diffusion dialysis device using the ion exchange membrane is constituted as follows: the ion exchange membrane and the chamber frame are sandwiched between the liquid introduction frames, and the ion exchange membranes and the chamber frames are alternately stacked between the liquid introduction frames, and the two ends are connected with each other. The fastening frame is fastened so as to alternately form recovery chambers and drainage chambers inside. [0003] As one application of the dialysis device, acid recovery or alk...

AI Technical Summary

Problems solved by technology

Since the bolt fastening type battery tank is fastened by arranging fastening bolts on the outside of the real part of the chamber frame, the fastening force of the bolts is not directly transmitted to the real part of the chamber frame, but is transmitted through the fastening frame. while transmitting force, which will cause the fastening frame to produce deflection deformation

If the deflection deformation of the fastening frame becomes large, the substantial part of the chamber frame to be fastened will be deflected and deformed, causing problems such as external leakage and internal leakage.
