System of renewable energy accumulation
SUBSTANCE: invention relates to alcohol obtaining. A system of renewable energy accumulation represents a block of renewable energy sources, connected to a technological scheme of obtaining an alcohol. The block of renewable energy sources provides thermal and electric energy for supporting the processes in the scheme of the alcohol obtaining.
EFFECT: invention makes it possible to provide ethanol obtaining from a biomass, with the application of renewable energy sources, which makes it possible to obtain alcohol on remote territories, possessing the required raw material.
The present invention relates to devices and systems for integrated natural accumulation currently available renewable energy sources, as well as excess that is not used at a certain time in electric networks, such as night failed electrical energy by conversion of these types of energy in the energy produced by alcohol.
Known devices for energy storage methods of electrolysis of water to produce hydrogen, for example, [1, 2] according to the invention to the author's certificate of the USSR No. 1084340 (analog) and RF patent No. 2399786 (similar).
The disadvantages of these and other similar hydrogen energy devices is the inability to create large storage tanks, and the impossibility of transporting hydrogen through pipelines because of his extraordinary fluidity through various leaks and welds. Leaks create hydrogen mixed with oxygen in the air an explosive mixture. In addition, current technologies for hydrogen energy-consuming significantly compared to the received energy when it is used as fuel.
The known device the accumulation of heat and electricity from natural renewable energy sources, for example, [3, 4, 5] according to the invention to the author witnesses stwu of the USSR №1064039 (analog), according to the invention to the author's certificate of the USSR No. 969954 (analog) and RF patent No. 2095913 (similar).
The disadvantages of such devices heat accumulation are the need to build costly well-insulated container. Large leaks (up to 30% and more) for the transport of thermal energy through pipelines. Additionally, failure or very low efficiency of the reverse conversion of thermal energy into other forms of energy, for example, in electric.
A disadvantage of the processes of accumulation of electric energy is the lack of currently cheap electrochemical devices with large capacity. The most effective such batteries are lithium-ion and sodium-sulfur, which start to be used for load leveling in electric networks, reducing failures night not used energy. However, conveying electrical energy by moving charged at the destination and returning the discharged batteries, even in the near future will be inefficient.
Known patent PRC No. CN101020888 System that produces ethanol by solar energy . This unit contains four solar collector-heater, consistently included among the processing nodes of a typical circuit training is Cai fermentation of raw materials, his distillation of the secondary distillation and rectification.
The disadvantage of this system is that it cannot long time to work in the absence of insolation, for example at night time. In addition, this unit is complicated in operation, as the series connection of solar heaters necessitates the control and regulation of different temperature regimes node type schemes and selection of thermal energy from the collectors.
Also known installation for the production of ethanol and related products, the fermentation of which is depicted in Fig.2, S. 114-115, and bragadireanu unit and a distillation column in Fig.5, S. 124-125  (see Yarovenko C. L. Handbook on the production of alcohol. Raw materials, technology and technochemical. M., 1981).
Figure 2, S. 114-115 shows detailed hardware and technological scheme of preparation of biomass and fermentation in fermentation vats (POS.46, 47) using steam. Output transmission capacity (POS.50) Mature mash is pumped by the circulation pump on bragadireanu unit and a distillation column, Fig.5, S. 124-125. The last picture is a detailed flow chart of the distilling part of the installation POS.37 indicates the use column, and POS.15 - distillation column.
The disadvantage of this setup in more power consumption is x to produce process steam and the cost of electrical energy.
To ensure technological processes specialized companies that produce large amounts of alcohol-containing materials are, as a rule, their CHP plant for the production of alcohols with superheated steam and electricity.
To bring this installation to the sources of raw materials and to reduce or eliminate the cost of manufacture of the industrial process steam and electricity, it is advisable if you utilize this renewable or unused in any period of time of energy.
Closest to the claimed invention (the prototype) is "the Way of the accumulation of natural energy..."  by heating biomass in mahantango to obtain a combustible synthesis gas by RF patent No. 2177081.
The disadvantage of such devices is low efficiency, is also due to the need for further purification of the synthesis gas to increase its energy potential, compression, etc. To store the synthesis gas in large volumes will require special storage facilities. The production of synthesis gas from biomass even at thermophilic regime in the summer time is a slow time process. To create thermophilic regime in the cold winter time it is necessary to use a large portion of the produced synthesis gas, which makes such bio is inefficient gas.
The technical result is an increase in the number of such installations that do not require permanent centralized power sources that can operate independently from wind, solar, hydraulic energy in the aggregate, or by one or more of their species, as well as from an unused redundant at the moment electric power from standard networks. Ultimately, this will increase the volume of produced products and bring these plants to the availability of raw materials for the production of alcohol.
The technical result is achieved by the accumulation of irregular energy renewable sources of energy in the form of heat in the heat accumulator, which is used later in the installation to obtain alcohol.
The technical challenge lies in the development of integrated energy storage from currently available renewable sources and from other excess unused energy by converting them into the latent energy of the product alcohol.
The problem is solved as follows.
The system of accumulation of renewable energy is a unit of renewable energy sources connected to the technological scheme of obtaining alcohol. Block sources contains heat accumulator with two Heaters, two input and d is uma output heat exchangers, solar collector, wind energy installation, turbine, multi-stage multiplier, an electric generator and a vortex generator, while the solar collector is connected to one input of heat exchangers of the heat accumulator, the outputs of the wind power installation and a turbine connected to the inputs of a multi-stage multiplier, one output of the latter is connected with an electric generator supplying one of the heating Elements of thermal battery and the second output of the multiplier is connected vortex generator, the output of which is connected to the second input heat exchanger of the heat accumulator, the second heating coil through which the switch is connected to the redundant networks at the moment of electric energy. Fermentation vessels technological scheme of obtaining alcohol is connected with one output of the heat exchanger of the heat accumulator, and its bragadireanu apparatus to the second output heat exchanger heat accumulator unit of renewable energy sources.
Technological scheme 1 obtain alcohols containing line 2 preparation of biomass, fermentation vessels 3, pump 4, bragadireanu unit 5 and the rectifying column 6, is connected to the unit 7 sources of renewable energy, providing electricity and heat to sustain the process accounting process flow 1 obtain alcohols.
Depending on the availability and quantity of wind or hydraulic energy is used in the operation of the wind turbine 8 or turbine 9, which through a multistage multiplier 10 (Overdrive gear) rotates the electric generator 11, supplying one of the heating Elements 12 of the storage tank 13.
To increase the heat introduced  vortex generator 14 connected to one of the heat exchangers 15. When there is solar energy used in the operation of the solar collector 16 connected to the other input of the heat exchanger 17.
The required temperature of the heat accumulator can also be supported against excessive in electric networks, for example, night failed energy. Another ten 75 thermal power through the switch 19 is connected to the electric network 20.
Fermentation vessels operating at a lower temperature, is connected with its output heat exchanger 21, and bragadireanu unit to the second output heat exchanger 22. The outputs 23 bragadireanu unit designed to receive Barda, fodder yeast, carbon dioxide, and the output 24 of the distillation column to obtain alcohol.
The proposed System of accumulation of renewable energy by converting it into alcohol works as follows.
In the flowsheet polucheniya alcohol on line 2 is prepared biomass and forwarded to the fermenting Tun 3 (there may be several). Effective thermal regime fermentation tank provides hot water through the heat exchanger 21, and mixed if necessary, cold water. Mature mash pump 4 is pumped into bragadireanu unit 5, which is fed into thermal energy from the heat exchanger 22.
The necessary temperature capacity in the storage tank 13 is provided with sufficient solar insolation from the solar collectors 16 through the heat exchanger 17. In the presence of wind power or hydraulic energy from the stream is used by the turbine 8 or turbine 9, which rotate multistage multiplier 10. The multiplier spins a generator 11, which is loaded on the heating coil 12, or vortex generator that supplies heat to the heat exchanger 15. If there is a possibility to use cheap, for example, night failure of electricity through the switch 19, the heater 18 of the storage tank is connected to centralized power grids 20, currently has excess unused electrical energy.
Depending on the required thermal power accumulated in the storage tank 13, use one of the currently available types of renewable sources or their combination, if the received energy from one source sufficient to engineer the economic process.
In particular, solar energy converted in the reservoir 16 into heat energy supplied to the heat exchanger 17 only in the daytime. In the presence of wind and/or hydraulic energy operating wind turbine 8 and/or the turbine 9, which through the multiplier 10 rotate the electric generator 11 and vortex generator 14. Thermal energy from the vortex heat generator enters the heat exchanger 17, and the electric energy to the heater 12.
Such a scheme allows electrical energy from generator 11 to use automation (not shown in the drawing), as well as for other own needs "System...", ensuring its autonomy from the mains, if the latter is absent.
Irregularly incoming heat energy from the heating Elements 12, 18 and heat exchanger 15, 17 is collected and stored in the heat storage tank 13. From the output of the heat exchanger 21 hot water enters the low-temperature fermentation vessels 3, and its temperature can be adjusted by adding cold water from the highway.
From the output of the heat exchanger 22 hot water is available in bragadireanu unit 5 which is supplied by the pump 4 from the fermentation tank 3 Mature wine. Well-known scheme with output bragadireanu unit raw material is fed to distillation column 6 and at its output 24. Output bragadireanu what about unit 5 receive low-quality fuel and raw alcohol, and output columns 6 - alcohol rectified. Output 23 bragadireanu unit 5 are also associated raw materials: feed the yeast and the bard.
Implementing the required temperature conditions, the proposed system allows to obtain different types of alcohol, the most popular of which is ethanol.
The proposed system of energy storage in the form of fuel alcohol-ethanol has wide applicability for the following reasons:
- Ethanol is a well known substance. The use of ethanol as a fuel for internal combustion engines developed in many countries of the world. Fuel ethanol unlike absolutized alcohol can be obtained by the simplified method, with significantly less energy. Can be transported by rail and pipeline transport.
- Ethanol can be produced from any biomass of plant origin, resources are practically unlimited.
- Ethanol can be stored under any climatic conditions for an unlimited time.
- Ethanol is a promising fuel for electrochemical generators with REM-converters for direct production of energy in electrical form.
- The technology of ethanol production can have a modular structure, low thermal inertia, which allowed the use of the entire produced in irregular mode of the wind, solar, hydraulic energy or unused in the networks of electric power both for individual types of renewable sources or in their entirety.
