回答: 日本福岛核污水低成本处理方法 由 丁成玉 于 2021-04-18 15:08

Recently, Japan’s decision to discharge Fukushima nuclear sewage into the ocean has caused controversy among the public. From the perspective of environmental protection, the best policy is to purify the nuclear sewage and discharge it. I have a low-cost purification method, which is to use the principle of "D pump" (see https://club.6parkbbs.com/chan2/index.php?app=forum&act=threadview&tid=13518331) to make a low-cost evaporator. The potential energy of the evaporated clean water is directly converted into vacuum (energy), and the "vacuum evaporation without vacuum pump" is carried out. The laboratory verifies that it can run for a long time, and it is unmanned and maintenance-free. A 10 cm pipe diameter "D pump" 》The evaporation rate is the same as that of a 20-kilowatt jet pump, at the level of "15kg/square meter hour". The 1.0 version of the evaporator (Chinese patent https://www.zhangqiaokeyan.com/patent-detail/06120200395934.html) is shown in Figure 1: 6park.com

The plastic pipe larger than 10 meters in "D Pump" has a diameter of 10 cm. The section connecting the evaporation chamber needs to be lined with spiral steel wire to avoid being crushed. It can be inclined and bent appropriately according to the terrain.
     In order to further reduce costs, solar heating can be used, which is version 1.5 of the evaporator, as shown in Figure 2:

One sewage tank can link multiple evaporators. As long as the evaporator is sufficient, the Fukushima nuclear sewage in Japan can be processed within one year.
      There is also a more energy-saving method and the 2.0 version of the evaporator that recovers the residual liquid from the distillation and enriches the tritium, waiting to be published.
