Background
The diffusion dialysis membrane device is a device which takes concentration difference as driving force to further realize acid-base separation, and consists of a diffusion dialysis membrane, a liquid distribution plate, a reinforcing plate, a liquid flow plate frame and a fastening device. Because the diffusion dialysis membrane is tightly pressed by the fastening device through the nut or the hydraulic device, the fastening effect is influenced by the running time, the tightness between the membrane and the liquid distribution plate is weakened, and the phenomenon of liquid leakage of the diffusion dialysis membrane stack in the production process is caused. The leakage amount can reach 3-8% of the whole treatment amount. Thus, not only is the waste of the treatment feed liquid caused, but also the cleanliness of the equipment operation environment is reduced, and the production is influenced.
For the case of diffusion dialysis leakage, the methods currently employed are divided into two, one for collecting leakage and one for improving the fastening means. The common practice of collecting leakage liquid is to arrange a liquid receiving tank or a drain ditch at the bottom of the membrane stack, collect the leakage liquid in the tank or the ditch, and then flow into the drain ditch for collection by gravity. The conventional way of improving the fastening device is to improve the combination mode of the diaphragm and the plate, such as disc cylindrical arrangement, or hydraulic fastening, automatically adjusting fastening force according to the set fastening value, and the like.
In the above treatment method for diffusion dialysis leakage liquid, although the leakage liquid can be collected by the method of collecting and directly discharging the leakage liquid by the leakage liquid collecting tank, the raw material leakage liquid is mixed with other treatment waste liquid in the drainage ditch, such as waste acid or waste alkali of diffusion dialysis treatment, the leakage liquid is still acid or alkali, and the mixture with other waste water not only increases the treatment difficulty of the waste water, but also increases the corrosion of drainage, thereby increasing the corrosion risk of the drainage system. However, if the structural form of the compacting device is changed, all production lines need to be replaced synchronously, and flexible adjustment cannot be realized.
