Description

Technical Field

[0001] The utility model relates to the technical field of bipolar membrane electrodialysis experiments, in particular to an integrated bipolar membrane electrodialyzer for experiments. Background Art

[0002] The bipolar membrane electrodialyzer utilizes the unique properties of the bipolar membrane to decompose water into hydrogen ions and hydroxide ions under the action of an electric field. The separation and migration of different ions are achieved through the selective permeation of the ion exchange membrane. The bipolar membrane electrodialysis pilot test device is a small experimental device used to study and test bipolar membrane electrodialysis technology.

[0003] With the rapid development of my country's economy, all walks of life have been rapidly developed, and biology is no exception. More and more biological equipment is being used by us, especially electrodialysis equipment. Electrodialysis is widely used in chemical industry, light industry, metallurgy, papermaking, seawater desalination and environmental protection. In recent years, it has been promoted and applied to the purification and research of biological products such as amino acids, proteins, and serum. General electrodialysis equipment is mainly composed of membrane stacks and water pipes. The water in the water tank enters the membrane stack through the water pipes. However, when the aqueous solution enters the water pipes, it often vibrates violently due to pressure, causing the interfaces between the water pipes to loosen and affect the quality of the solution. The entire production process makes the production dangerous and inefficient. Traditional electrodialysis devices are all rectangular, and the electrode plates are also rectangular. The placement method is single, which easily leads to uneven distribution of working current and uneven distribution of liquid on the membrane surface, resulting in low membrane efficiency and membrane burning and other technical problems. In addition, traditional electrodialysis devices are not easy to disassemble and assemble, and have too many parts, which makes it difficult to assemble and operate. Therefore, an electrodialysis device with a simple structure, easy assembly and disassembly, and uniform working current distribution is needed. Therefore, in order to overcome the shortcomings of traditional electrodialysis devices, an electrodialysis experimental device that is easy to install and operate is proposed.

[0004] An existing patent (publication number: CN207478337U) discloses an electrodialysis experimental device that is easy to install and operate, comprising a liquid storage tank, a delivery pump is provided at the bottom of the liquid storage tank, a liquid inlet is provided at the top of the liquid storage tank, a liquid delivery pipe is connected to the top of the delivery pump, one side of the liquid delivery pipe is connected to a filter device, one side of the filter device is provided with a filter screen, one side of the filter screen is connected to a liquid inlet pipe, one side of the liquid inlet pipe is connected to an electrodialysis device, an upper electrode plate is provided at the top of the electrodialysis device, a membrane stack is provided below the upper electrode plate, a lower electrode plate is provided at the bottom of the electrodialysis device, one side of the electrodialysis device is connected to a sewage pipe, one side of the sewage pipe is provided with a sewage trough, the other side of the electrodialysis device is connected to a water outlet pipe, and one side of the water outlet pipe is provided with a water storage tank. The electrodialysis device has a simple structure, few parts, and is easy to install and operate. Filtration is performed before electrodialysis to prevent impurities from clogging the device. The circular electrode plates can make the current distribution uniform and improve work efficiency.

[0005] In response to the above problems, existing patents have provided solutions. However, the existing bipolar membrane electrodialysis small-scale experimental device does not have a reinforcement structure when in use, resulting in it being placed movably on the top of the operating table during use, making it unable to resist the impact force caused by accidents, making it easily affected by the outside world during the experiment. At the same time, the storage tank arranged inside it does not have a protective structure on the top during use, resulting in the experimental liquid stored in the storage tank being easily affected by the outside world, which is not conducive to user use.

[0006] Therefore, an experimental integrated bipolar membrane electrodialyzer is proposed. Utility Model Content
