Embodiment Construction
[0024] Hereinafter, the present invention will be described in detail with reference to the drawings.
[0025] figure 1 It is a representative figure which shows the whole structural element of this invention. The main components of the present invention include an evaporating device made of a solar heat collector, a heat exchanger, and a hand pump for water supply, wherein the solar heat collector evaporating device is composed of a left and right rotating solar concentrating reflective surface with a sun tracking structure and a heat exchanger. The central axis of the focal point of the reflective surface is provided with a tube or cylinder with the functions of expanding, condensing, evaporating and reheating water vapor through solar energy. The heat exchanger converts the water flowing into the evaporation device from the The distilled water discharged from the evaporator is used for heat exchange, and the manual pump for water supply is used at the initial start-up.

The object of the present invention is to provide a water distillation device using solar heat and a distillation method. More specifically, the water distillation device comprises: a solar collector type solar evaporator; a heat exchanger for preheating water to be evaporated together with the solar evaporator and for cooling distilled water; and a hand pump for water supply, allowing the solar evaporator to be filled with water at the initial state of operation. The solar evaporator comprises: a sun tracking cylindrical parabolic mirror solar collector having a reflective surface capable of reflecting sunlight to collect the sunlight wherein the focal axis of the sunlight reflecting surface is fixed and the sunlight reflecting surface rotates back and forth around the focal axis; an expanding water pipe for heating water with solar heat to expand the same, on the focal axis of the solar collector; a condensation water bath for cooling the expanded water to condense the same; an evaporation water bath for heating water simultaneously with solar heat and high temperature vapor to evaporate the same, on the same focal axis of the solar collector; and a vapor re-heating vapor pipe for heating vapor generated at the evaporation water bath with solar heat. Therefore, the present invention can distill sea water or various kinds of water at a high efficiency through the complex process of pumping water, heat exchange, vapor reheating and evaporation by using only solar energy without energy such as an oil or electricity.
Description
technical field [0001] The present invention relates to a distillation device and distillation method for various waters utilizing solar energy (in the present invention, "various waters" refer to "seawater" or "various waters such as waste water", hereinafter referred to as "water"), More specifically, it relates to a method for distilling various waters including seawater and an apparatus thereof, which is constituted as follows: in a solar collector having a high-performance solar heat collection function such as a cylindrical parabolic mirror solar collector, a fixed The focal axis of the reflective surface of the collector, and the cylindrical parabolic mirror rotates left and right with the focal axis of the reflective surface as the center to form a cylindrical parabolic mirror solar collector that tracks the sun. The support rods of the focal axis of the surface are respectively provided with expansion water pipes and condensation water tanks, and the water is heated b...
