Electricity-generating system using solar heat energy

An electricity-generating system using solar heat energy comprises:

• a fixed body (11) in the form of a mesh net having mesh openings, which has a spherically-shaped top portion extending above the ground;
• a condenser lens (12) coupled to each of the mesh openings of the fixed body (11), which focuses sunlight at the bottom portion of the fixed body (11);
• a condenser unit (10) installed at the bottom portion of the fixed body (11), which includes a collector lens (13) that increases the concentration of energy focused through the condenser lens (12) and transfers heat to the bottom of the body thereof;
• a heat storage tank (30) combined with the bottom portion of the fixed body (11), which has a heat storage medium (40) filled inside the body thereof, and which heats and stores the heat storage medium (40) by means of heat energy transferred through the collector lens (13);
• a circulation conduit (50) which has an upper plate-shaped coiled tube (51) and a lower coiled circulation tube (52), which is stacked and contained in the heat storage tank (30), and which selectively moves steam to each component through the operation of a valve of a circulation pump (53);
• a generator (60) for generating electricity when steam in the upper plate-shaped coil tube (51) of the circulation conduit (50) is heated and converted to a sensible heat state in the heat storage tank (30) and the sensible heat steam is discharged in order to drive a steam turbine (61);
• a first heat-sensitizing unit (70a) for further thermally contracting the sensible heat steam that passes through the generator (60);
• and a generating unit (20) having latent heat steam that is thermally contracted by the generator or the first heat sensitizing unit (70a) pass through the lower coil circulation tube (52) of the circulation conduit (50) and through the inside of the heat storage tank (30) to be heated, and including a second heat-sensitizing unit (70b) thermally contracting the heated sensible heat steam, wherein the heat storage medium (40) in the heat storage tank (30) is heated by the condenser unit (10) and performs heat exchange with the upper plate-shaped coil tube (51) and the lower coil circulation tube (52) in the tank, sensible heat steam is fed therein, the sensible heat steam discharged through the upper plate-shaped coil tube (51) drives the steam turbine (61) in order to generate electricity, latent heat steam is further thermally contracted when passing through the first valve (54a) and the first heat-sensitizing unit (70a), the latent heat steam is supplied to the lower coil circulation tube (52) through a second valve (54b) so as to exchange heat with the heat storage medium (40), and the sensible heat steam heated in the lower coil circulation tube (52) is thermally contracted when passing through a third valve (54c) and the second heat-sensitizing unit (70b), and is supplied to the upper plate-shaped coil tube (51) through a fourth valve (54d) in order to be circulated.
