Electrolyzer for chlorine engineering

This post was last edited by Benbenxuan on 2011-6-30 16:15 1# tianleiws This problem is a bit big, I don’t know where to put it. To talk about the similarities and differences, let’s take your Beihua electromechanical tank as a comparison and briefly mention a few major differences. 1. The chlorine project does not have a high-level brine tank, but a super-fine brine storage tank. The brine from the primary brine directly enters the resin tower for secondary refining, and then flows into the super-refined brine storage tank. A pump is used to supply brine from the storage tank to the battery cell. 2. The chlorine project is a three-tower series refining system. After the regeneration tower is regenerated, it is directly connected to the system for inspection. The Beihua Chemical Machinery is a two-tower series system. 3. The secondary refining and regeneration process is quite different. The chlorine project includes air bubbling, forward washing and backwashing, which is relatively complicated, but the resin washing will be more thorough. 4. The battery tank structure is different, the unit tank area is larger and artificially extruded. 5. The tank head piping is extremely simple, there are no independent complex pipelines for pure water, light salt water, etc. and tank head instruments. There will be no independent fresh brine supply system after the tank is shut down. 6. The circulation system is different. The ratio of the fresh salt water returned to the tank and the salt water entering the tank in the chlorine project is 1: 1 is equivalent to two pumps supplying brine to the battery tank at the same time. 7. The acid adding methods are different. The single tank of the chlorine project adds acid independently. 8. The hydrogen venting methods are different. The hydrogen venting in the chlorine project relies on manual operation to empty the tank. When driving, a dedicated person needs to hold a walkie-talkie to adjust on site, which is very inconvenient. 9. The operating pressure is different, but the operating pressure of the 0-pole pitch cell of Beihua Machinery has also dropped. 10. The adjustment methods of hydrogen chlorine are different, which depends on the operating pressure of hydrogen chlorine. Chlorine is not adjusted by Haiyou PCV216 like Beihua machine, but is ensured by the return flow of the booster fan treated with hydrogen chlorine. This kind of adjustment is not sensitive enough. 11. Dechlorination methods are different. Beihua Machinery prefers vacuum pump dechlorination, while chlorine engineering prefers jet vacuum dechlorination. 12. The control systems are quite different, so I won’t list them one by one. Experts and leaders are welcome to add anything else. If there are any incorrect points, please let me know.

Nothing is absolute. If you feel that others are deficient, you can improve, so our company has made a lot of improvements. 1. For safety reasons, we added salt water and alkali high-level tanks ourselves. It is very easy to use and very safe. 2. Our company also uses two towers, secondary brine. You can put forward your own requirements when designing this. 7. Generally, acid is not added directly. It can be added directly to the circulating salt water tank to control the PH of the salt water. 8. For hydrogen venting, it would be convenient if you just add a regulating valve to the circuit. It can also be vented during hydrogen chloride treatment. 11. Vacuum pumps are now also used for dechlorination.

I have a copy of the electrolytic cell maintenance work instructions that I wrote. I wonder if you can use it.··

What the second floor said is not entirely correct.: 1. There is no high-level tank in the initial design, but you can request to add it according to your own needs. This part of the process design can be proposed at the design meeting. High-level tanks can be added for both hydrochloric acid and alkali. 2. Two-tower and three-tower operation of secondary brine can also be designed according to the requirements. Generally, two towers are designed to save money, but you can also ask for it. Looking for three towers, two towers running calcium and magnesium content for each problem 3. The chlorine project is generally a secondary brine regeneration process in cooperation with Japan Niu Shui. PLC controls 20 steps of regeneration, which is very reliable. 5. The tank head piping design is not simple. There are pure water hydrochloric acid and light salt water pipes. There are instructions for the light salt water supply tank in the parking regulations. The instruments are complete. If you have money Most of them can be equipped with remote meters. 7. There are also single tanks for adding acid, but they are generally not used because they are difficult to control. Because there is light salt water circulation, acid can be added to the light salt water. 8. For venting, you can propose adding an automatic valve at the design meeting, which is also very convenient. 9. In terms of operating pressure, there are low and high tanks in chlorine projects now, and every company is different. 10. Chlorine projects There is a similar valve for regulation. 11. Liquid ring vacuum pumps are now used for dechlorination. 12. The control system is not bundled and you can choose it yourself. The above are all based on the actual actual situation of the factories I have worked in. Process problems can be modified. You can compare the process of your Beijing chemical machine and propose process technical modifications if you think it is good. The process indicators all serve the maintenance of electrolytic cells and ion membranes. Of course, each cell has its own maintenance methods. In fact, the real difference lies in the electrolytic cells, such as pole distance, coating, etc. This cannot be changed. Many people say that the cells of Chlorine Engineering are better than those of Beihua Machinery, but of course they are more expensive.
