Description of the drawing
The invention is illustrated with the help of the Figures.
The general view of the suggested plant is given in Fig. 1. The working heat supply to the engine plant is shown in Fig. 2. Detailed Description of the Invention
The energy system designed to generate electrical power, cold and fresh water from environment activates three heat insulating containers 1 (A, B, C) of high pressure (200 atm), each is equipped with two input (A2, A4), (B2, B4), (C2, C4) and output (Al , A3), (B l , B3), (CI , C3) vents. At this, one input and one output vent of the above containers (Al , A4), (Bl, B4), (CI, C4) is unified into a closed line comprising the heater 2 and the pump 14. The other input vents (A2, B2, C2) are connected with the reserve and supply tank 5 designed for working heat through the pipelines and one common vent 3 and the pump 4. The other output vents (A3, B3, C3) are connected with the engine plant 6 through the pipelines. The output shaft of the engine plant 6 is connected with the electrical power generator 7. To achieve continuous and steady operation the system might be equipped with the additional reserve combined sources of the electrical energy 15 such as gas turbine, hydraulic turbine or wind-turbine plants, the gas engines, the solar batteries, the storage batteries, etc. Selection depends on task, location, and climate conditions. The paralleled systems' use might allow compensating electrical energy consumption at the peak moments of its consumption by the compressor, the pumps and other energy consuming system units.
The engine plant 6 is designed to discharge working medium into the cold recovery system, which activates the container 8 to accept the waste working medium supplied from the engine plant connected with the plant proving for additional cooling and condensing of working medium. In its turn, the last one might comprise the compressor 9, the heat exchanger-regenerator 10 for the heating system and the condenser 1 1, which are interconnected through the pipes. The condenser 1 1 is connected to the heat exchangers-condensers 12 with the help of a joining pipe. The last ones are installed to interact with the ambient air and to condense fresh water, which is supplied in to the water chamber 13. The heat exchangers-condensers 12 are connected with the above reserve and supply tank 5 to supply the working medium inside.
The operation of the suggested invention is explained with the help of the implementation example given below.
The heat insulating containers A and B are filled with liquid C02 at the temperature - 56 C having opened the common vent 3 and A2, B2 and having activated the pump 4 of the reserve and supply tank 5. Then the given vents are to be closed. The container C is now empty to be filled in with the waste C02. Next, open the vents Al and A4 in the container A. Heat the working medium up to the temperature of - 18 ... +20 C into the closed line through the pump 14 and the heater 2. Then close the vents Al and A4. Simultaneously, open the vents B l and B4 and heat the working medium up to the temperature of -18 ... + 20 C through the pump 14 and the heater 2. After this, open the vent A3. The medium is supplied into the engine plant 6 under the pressure of 50 to 70 atmospheres. The output shaft of the last one is connected to the electrical power generator 7. Thus, the electrical energy is generated.
The waste C02 is supplied into the container 8 from the engine where it is cooled up to -79 C (50% as dry ice and 50% as gas). Then it is transformed as liquid of the temperature -56C through the compressor 9 whose shaft might be connected with the output shaft of the engine plant 6, through the heat exchanger-regenerator 10 designed for the heating system (where the gas is compressed and heated up to 85 to 1 IOC) and through the condenser 1 1. Thus, the cold is generated. The liquid C02 is supplied from the condenser 11 into the heat exchangers-condensers 12 where the water vapors are condensed and fed into the water chamber 13. Thus, the fresh water is generated.
Collection of the hazardous waste C02 as well as its use as working heat improves the ecological compatibility of the suggested system.
Hereby, the suggested system allows simultaneous generation of electrical energy, cold and fresh water from environment when compressed gas or liquid under high pressure is used as the working medium.
Industrial Applications
The present invention is implemented using the universal modern equipment available in the industry.
