Pipeline flow limiting method by using etheric entropy water energy of deep sea water

The invention discloses a pipeline flow limiting method by using etheric entropy water energy of deep sea water. As water of seabed of deep sea at 2,000 m or below, particularly water above an oceanic trench, is relatively small in etheric entropy, substantive energy is stored; only if a heat insulation water pipe is inserted into the seabed and a water inlet is formed in the lower end of the heat insulation water pipe, the deep sea water can be pumped through a deep sea water collection device, and high-temperature water is sprayed from a water outlet in the upper end of the heat insulation water pipe; the temperature of the high-temperature water is not less than 40 DEG C. The deep sea water collection device is a controllable deep sea water collection device with the patent number of CN100545622. The high-temperature water prepared by the pipeline flow limiting method can be widely applied; furthermore, the deep sea water is rich in energy storage, so that the energy cannot be completely excavated forever,
