FIELD: power engineering. SUBSTANCE: device comprises a lower reach 1, an upper reach 2, a water conduit 3, a turbogenerator 4 and surfaces 5. Surfaces 5 are made as capable of receiving atmospheric moisture from the air flow and delivering it to the upper reach. Besides, surfaces 5 are raised to the height above the dew point for these atmospheric conditions. To support the surfaces 5, balloons or airships 6 are used. EFFECT: expansion of functional capabilities and increased specific capacity of HPP by using maximum possible difference of heights between upper and lower reaches from height of actual condensation of atmospheric moisture in a cloud to ground level. 2 dwg
The invention relates to hydropower and can be used for energy, stored in atmospheric moisture anywhere in the world. There are various versions of HPP (see, for example, http://ru.wikipedia.org/wiki/gas), using the energy of the water flow resulting from the height difference of two sides of a dam across a river. This hydroelectric power station has an upper water (the reservoir behind the dam), lower reach (river level downstream of the dam), connecting conduit and the turbine generator, which uses the energy of the water flow in this conduit for electricity generation. Common faults such HPS is that they require significant capital costs for the construction of the dam, occupy a considerable territory under the reservoir, environmental damage and is usually removed from the consumer. In addition, there is always the potential danger of a possible failure of the dam. To a certain extent, all of these deficiencies are the result of a relatively small elevation at the huge volumes of water, characteristic of most lowland rivers. Closest to the proposed solution is patent RU 2407914 C1 (METHOD AND apparatus RENEWABLE production of ELECTRICITY AND CLEAN WATER). In this way serves to provide electricity and distilled water by using naturally in the waters of the clouds. This is achieved by raising the water collection (playing the role of the upstream) to a level just below the clouds using tethered balloons, call of condensation and loss of moisture by spraying fine chemicals balloon above the collection and delivery of the collected water to the ground through the connecting pipe (non-pressure pipeline). This device has a number of serious structural and physical disadvantages associated with the method of condensation of water by creating spontaneous artificial rain and collect the rain in a horizontal header: aerodynamic instability of the sump in case of strong winds, the structural complexity of the dispersion and delivery of the reagent and purification of water from it, the ambiguity of the loss of moisture from the introduction of the reagent (http://en.wikipedia.org/wiki/Cloud_seeding), high probability of ice just under the cloud with the destruction of the structure, significant inconsistencies hydraulic flow, and the related inability to use pressure conduit to reduce energy losses in the pipeline. The present invention describes HPP, containing upper and lower reach, the conduit and the turbine generator, and hydroelectric power plants equipped with surfaces made with the possibility of admission of atmospheric moisture from the air stream and deliver it to the upper downstream, and these is arnosti raised to a height above the dew point data for atmospheric conditions. These surfaces can be maintained at the height of the balloons or airships. They can also be made in the form of a kite or glider. The surface can be provided with a drainage system for collecting atmospheric moisture, in the form of grooves and tube channels, transmitting the collected water in the upstream face. Also, these surfaces may have full or partial metallization. In one of the embodiments of the conduit hydropower plant can be divided into several sections with intermediate turbine generators. The technical result is to enhance the functionality and increase the share of hydroelectric power by using the maximum possible height difference between the upper and lower downstream (from the top of a real condensation of atmospheric moisture in the cloud to ground, while the prototype only from the level of the lower edge of the clouds to ground level), the extension of the territorial applicability HPP (anywhere on the planet, while the prototype either in the ocean or in areas of intense rainfall), the reduction of the dimensions on the earth's surface, mobile (including for use in transport, for example, to supply electricity and water, ocean-going vessels). In addition, it provides anywhere obtaining clean water for drinking and irrigation, without causing environmental damage due CPA is additional small hydro flows compared to conventional hydropower plants. Another advantage is the reduction of capital and material intensity HPP. It is known (http://en.wikipedia.org/wiki/Solar_energy#Energy_from_the_Sun)that the solar energy reaching our planet, about 10,000 times greater than the needs of humanity. It is about a quarter is spent on evaporation of water, which is more or less uniformly accumulated in the atmosphere. Standard hydropower are able to use only a small part of this energy, as all precipitation lose most of their potential energy on the way to the ground to overcome the resistance of the air and hitting the ground, and in addition the majority of precipitation falls in the ocean or on the plain, which makes it impossible or unprofitable for them. In order to use this potential energy more effectively, it is necessary to collect water at the height where it condenses, and to operate in a hydroelectric power station the entire elevation and in any place of the planet. This is the essence of this invention. The device of this HPP is shown in figure 1 and includes the lower reach 1, the upstream face 2, a conduit 3, a turbine 4, a mesh, a woven or film surface 5, a balloon or airship 6 and fastening cables 7. The balloon or airship 6 raises the surface 5 to a height above the dew point data for atmospheric conditions (also known in meteorology line to which densely or cloud base). There supercooled atmospheric moisture from the incoming air stream begins to condense (to gather) on the mesh surfaces 5 (for example, of polypropylene mesh used in gathering systems fog). The drainage system on the surfaces 5 removes the water in the reservoir (upstream water 2)where water under pressure the entire elevation (2-3 km) flows through the conduit 3 into the lower reach 1 on earth, producing electricity in the turbine 4. The mechanism of condensation on surfaces 5 consists in the creation of centers of condensation or crystallization of atmospheric moisture, which is similar to the effect of the reagent in the installation of the prototype, and in a purely mechanical Assembly, moisture, already condensed in the cloud, which is similar to the operation of the gathering mist (http://en.wikipedia.org/wiki/Fog_collection). When this moisture condensation occurs uniformly, but not spontaneously, as in the installation of the prototype. The optimal height of the surfaces 5 depends on the type of clouds and corresponds to a maximum water content in the cloud (typically about 1 km above the base of the clouds). The whole setup can be collected on any industrial site, and then to mount permanently in place, necessary for consumers of electricity and water, lifting and moving it entirely by balloon or airship 6. If this is the place blow the pic is aannie steady winds, or is it a portable installation (for example, for tourists, military or rescue MES), it is possible to perform the surface 5 in the form of a kite or glider for self-retention of the entire installation in the air. The device of this HPP is shown in figure 2 and contains the lower reach 1 (receiver of drinking water), drainage system and sump 2 (top water), gravity-flow conduit 3 (aka hollow rope or cable 7), the turbo-generator 4 (which may be a portable or rescue facilities intended only for drinking water), tissue (e.g., from Aero or parachute fabric) or film (such as polypropylene or high-strength polyethylene) surface 5, which is part of a kite 6 (for example, type Flowform)held by the cable 7 (he is also the conduit 3). Such installation can be very light and compact collapsed. So it can, for example, be delivered to the venue and rescue operations, and to run there to get drinking water. In the General case, the conduit 3 may be performed either gravity (as in the prototype), or pressure (as in traditional HPS), which may increase the efficiency of such a setup. Modern structural materials allow the use of flexible pressure conduit 3 with a maximum water pressure of up to 200-300 atmospheres. Also the design can be re lisovana by dismemberment of the conduit 3 into several sections with intermediate turbine generators, fired the head of his section and transmitting electricity down the wire. Also the surface 5 can be performed with full or partial metallization (for example, woven metal conductors). This will increase the strength of the structure, to reduce solar heating, to enhance the condensation of water vapor by supplying electric field (for example, there are experiments to use for this corona discharge), and if necessary, to reduce icing due to the supply current. Icing can be used as a standard mode, since the system has automatic stability - the accumulation of ice the whole structure will fall in the higher temperatures of the atmosphere, and after the melting of the ice itself will be raised to the required height. So, this HPP can be applied almost anywhere in the world, without harming the environment. Calculations show that such a HPS can provide a small town, believing that ~100 m2surfaces 5 on each resident provides his needs in water (~1000 l/day) and household electricity (~150-200 kWh/month). 1. HPP, containing upper and lower reach, the conduit and the turbine, characterized in that it is provided with surfaces made with the possibility of admission of atmospheric moisture from the air is about flow and deliver it to the upper tail, moreover, these surfaces are raised to a height above the dew point data for atmospheric conditions. 2.
