Definitions

  • This innovation belongs to devices which use solar energy for useful purposes.
  • thermocells and photocells work on principle of an closed circle made of two different metals soldered to each other; electric current flows if there exists different temparature between two contact points.
  • Solar energy utilization in this case is about 2%.
  • Photocells convert solar energy directly into electricity. When exposed to electricity selenium photocells generate ellectric current. Utilization of electric energy in this case is also 2% approximately.
  • Up-to-date silicon cells reach the utilization degree up to 15%.
  • Solar energy is also used for heating water by exposing water to solar radiation in a thermally insulated basin with blackened bottom and a glass plate. Solar rays, when concentrated, can generate temperature between 100° and 500 C 1 even more.
  • Concave mirror is used for production of hot water, steam, and for distillation of seawater.
  • Figure 1 shows side view of the concave mirror made of alluminum coated with thin silver-, nickel- or chromium layer.
  • the Figure shows girder (2) connecting concave mirror to water reservoir (3), reservoir (3) with cover (4), manometer (7), lattice girder of the whole system (8), steel pipe for cold or seawater supply (6), and also steel pipe for hot water or steam outflow (7).
  • Figure 2 gives the mirror front view with the same details as on Figure 1.
  • Figure 3 shows moving joint directing the concave mirror always toward the sun, so that the mirror follows moving of the sun from the morning till the evening. This is achieved by two electric motors (10 and 12) which through gearwheels (14 and 15) bring the joint into the needed position, i.e. move it along horisontal and vertical path where gearwheels turn around axles (16 and 17) supplied " with pins (18 and 19) and fixed with metal disks (22 and 23) palced around grearwheels.
  • FIGS 3,4,5 and 6 show the position of the concave mirror at 9 am, 12 pm, 3 pm and finally at 6 pm.
  • FIG 9 shows the water reservoir in the moment when water level lowers to B line.
  • valve (30) openes to discharge water into concrete basins through the pipe (29).
  • water contains high percentage of salt, water heated in these basins by sun rays evaporates quickly and pure sea salt remains.
  • valve (30) closes and valve (25) openes.
  • pump (26) suplying cold or sea water into the reservoir would start to operate. The pump (26) stops operating when water in the reservoir reaches A line and at the same moment the valve (25) would close.
  • pipe (32) As pipe (32) is connected to the reservoir by pipe (31), like communicating vessel, water level in the reservoir is indicated by a float (35) in each moment, while weight (34) shifts the float (35) downwards by axle (33) and so prevents steam to lift the float, if too light, above the necessary level or even to throw it out of the pipe.
  • the indicator is necessary in case when the pipe which contains the float is made of steel. If the pipe, however, was made of transparent fireproof glass, the indicator should not be necessary.
  • Drawing 10 shows the other version of reservoir functioning with water in it circulating continually.
  • Cold water or seawater would be supplied to the reservoir continually by the pump (26a) and pipe (24a).
  • Valve (30a) would be opened constantly, in fact more or less closed when necessary.
  • valve (30a) closes as much as it is necessary to reduce water outflow.
  • valve (30a) opens more to let larger quantity of water to flow out. Therefore, valve (30a) regulates the constant level of water in the reservoir (3a), i.e. keeps water level always on the D line.
  • the condenser has a star-like shape so that as much of its surface as possible could be in contact with seawater.
  • Condenser (38) is fixed to sea bottom (41) by girders (40).
  • the device would function in the following way: In the period from 11 am. till 3 pm., when the pressure in the reservoir (3) is at its maximum, 7.92 bars, and when temperature in the reservoir is 170° C, approximately 1/3 of the steam under pressure is being delivered through valve (46) to miniturbine (43) which actuates electric generator (44) to store energy. in the accumulator which then actuates concave mirror through the joint both horizontally and vertically, i.e. directs it always toward the sun.
  • Diesel engine (45) serves to actuate electric generator (44) and to load the accumulator (42) in case of any turbine (43) failure or in case of extremely bad weather.
  • Turbocompressor receiving energy also from accumulator (42) serves to shift the steam to the condenser in the afternoon hours when steam pressure in the reservoir (3) is lower than in the condenser.
  • Device for production of hot water, steam, and for seawater desalinization is completely free of costs. If we are aware that 600 calories (2512 kJ) is necessary for evaporation of one Liter of water from 0 degrees till utter evaporation, then we shall see how much it could be saved.
  • the device is at its optimum operation when the reservoir contains saturated steam at 170° C and under pressure of 7.92 bars. Steam under quoted pressure and temperature in the condenser pounded by seawater of temperature from 18° C till 24° C turns very quickly into distilled water. Utter conversion of steam into water would happen during the night, so that in the morning there would be received large quantity of cooled distilled water, suitable for watering vegetables or fruits.
  • the device being utterly free of costs and autochtonous, is extraordinary suitable for warm areas. From the environmental point of view, It should be also noted that its operation is completely pure and without any harmful admixtures.
  • the device can serve for production of hot water (for hotels, etc.) or steam. In that case tap water should be poured into the reservoir and the condenser would be unnecessary.
  • One operator can serve 5 or 6 devices.
  • regulator pipe (32) can . be made of fire-proof glass. It is recommended to dye the float (35) in red colour for easy control of its movement. I consider this option more acceptable than the former one. Valve closing and opening procedure is the same as with the pipe (32) with indicator.
  • Regulator pipe (32) with water in it at the same level as in the reservoir, works on -the principle of connected containers, as the float (35) goes up and down just as water in reservoir (3).
  • Concave mirror is driven by two electric motors (10 and 12). Horisontal movement is achievable in a rather simple way by help of the electric motor (12): the electric motor (12) is moved evenly by electricity. The motor is regulated in such a way that it turns the concave mirror on the horizontal axes always toward the sun. The motor moves within the radius of 360 degrees. In fact, the motor (12) moves the concave mirror toward the sun during at daily light, and it keeps on moving during the night, so that it is turned toward the sun again in the morning.

Abstract

Miroir concave utilisé pour la production d'eau chaude, de vapeur ou pour la distillation d'eau de mer. Le miroir concave (1) est constitué d'aluminium revêtu d'une couche mince d'argent, de nickel ou de chrome et est relié à un réservoir d'eau (3) par une poutre (2). Le miroir (1) suit le mouvement du soleil au moyen de deux moteurs électriques (10 et 12) qui, par l'intermédiaire de roues dentées (14 et 15), amènent le miroir (1) dans la position requise.
