The system includes at least: a liquefaction regeneration unit including a liquefaction space where the vapor of an object to be heated is liquefied and a heating part for maintaining a liquid-like state; a vaporization unit for heating the liquid-like material by means of a heating part so as to generate a vapor; a fluid communication part for establishing fluid communication between the liquefaction regeneration unit and the vaporization unit; a processing unit for processing an object to be processed by using the vapor; a return pipe for returning the vapor used in the processing unit to the liquefaction regeneration unit; a liquefaction regeneration temperature control part for controlling the temperature of the liquefaction regeneration unit; and a vaporization temperature control part for controlling the temperature of the vaporization unit.

Three embodiments of an invention are disclosed in which sea water undergoes a desalination process accompanied by production of salable energy of value greater than the cost of the fossil fuel required, and which discharges brine to the sea at a temperature and salinity harmless to sea life.

Disclosed is a method of regenerating a phosphoric acid solution from a treatment liquid including silicon (Si), hydrogen fluoride (HF), and phosphoric acid, the method including removing the silicon by supplying hydrogen fluoride corresponding to a preset amount or more to the treatment liquid, removing the hydrogen fluoride by heating the treatment liquid to a boiling point of hydrogen fluoride or higher, and adjusting a temperature and a concentration of the phosphoric acid to preset values.

A water purification system with a centrifugal system and a frictional heating system consists of a centrifugal unit, a cavitation unit, a cooling condenser, a vertical shaft, and a pitot tube. The centrifugal unit and the cavitation unit are mounted along the vertical shaft so that the rotational movement of the vertical shaft is transferred onto the centrifugal unit and the cavitation unit. Non-potable water is directed into the centrifugal unit to separate heavy solids. Less populated water from the centrifugal unit is transferred to the cavitation unit via the pitot tube. The cavitation unit uses friction to generate phase change in the volume of less populated water which is then directed to the cooling condenser to produce potable water.

A gravity power and desalination technology system is provided, including a heat storage apparatus, an inner tube portion, a hot-air and vapor generator, and venting holes, a corrugated tube portion, an outer tube portion, an updraft wind power generator, and an artificial hydro power generator. The heat storage apparatus is provided in a lower portion and configured. The inner tube portion has an inner vent portion inside and disposed vertically over the heat storage apparatus. The hot-air and vapor generator is disposed between the heat storage apparatus and the inner tube portion. The venting holes are bored through the inner tube portion obliquely outwards. The corrugated tube portion is provided on a top portion of the outer tube portion. The updraft wind power generator and the artificial hydro power generator are installed in the lower portions of the inner vent portion and the outer vent portion, respectively.

The system includes at least: a liquefaction regeneration unit including a liquefaction space where the vapor of an object to be heated is liquefied and a heating part for maintaining a liquid-like state; a vaporization unit for heating the liquid-like material by means of a heating part so as to generate a vapor; a fluid communication part for establishing fluid communication between the liquefaction regeneration unit and the vaporization unit; a processing unit for processing an object to be processed by using the vapor; a return pipe for returning the vapor used in the processing unit to the liquefaction regeneration unit; a liquefaction regeneration temperature control part for controlling the temperature of the liquefaction regeneration unit; and a vaporization temperature control part for controlling the temperature of the vaporization unit. Then, the object to be heated is present in a solid state at ordinary temperatures, present in a vapor state and the liquid-like state in the liquefaction regeneration unit, present in the liquid-like state in the fluid communication part, present in the liquid-like state and the vapor state in the vaporization unit, and present in the vapor state in the processing unit and the return pipe.

An object is to provide a highly-efficient evaporator capable of effectively avoiding reduction in steam generation efficiency due to the Leidenfrost phenomenon while maintaining a heating surface in a heating chamber for steam generation in a high-temperature region to be subjected to the influence of the Leidenfrost phenomenon by not reducing heating power required for heating the inside of the heating chamber from outside or not heat-insulating the heating chamber. To achieve this object, a sleeve-like sheet made of foamed nickel is disposed as a foamed member 64 containing metal as a principal component near a heating surface 69 and along an entire periphery of the heating surface 69 in a heating chamber 68 formed inside a pipe body 67 to be heated from the outside in such a manner as to contact the heating surface 69. While water supplied to the inside of the sleeve-like sheet passes through this inside, the water is diffused to permeate the surrounding sleeve-like sheet. Evaporation of the water is finished before the water reaches the heating surface 69.
