In addition, the operation of such systems and installations stands out a huge amount of heat that is released into the atmosphere, which is impractical from an economic and environmental point of view.

In this system, it is possible to obtain not only liquid nitrogen, but also liquefied natural gas, and at the same time use the energy of nitrogen gas to perform useful work, using a turbine with an electric generator located on the same shaft as the turbine as a device for converting nitrogen gas energy.
Недостатками известной системы являются:  The disadvantages of the known system are:

- низкая эффективность газификации сжиженного газа, приводящая к невысокой эффективности всей системы;  - low efficiency of gasification of liquefied gas, leading to low efficiency of the entire system;
- высокая энергоемкость системы.  - high energy intensity of the system.
Заявляемое изобретение направлено на решение задачи расширения возможности разделения различных газовых смесей на составляющие, полного использования выделяемого при охлаждении тепла и холода при газификации сжиженных составляющих с получением высокой степени преобразования энергии с разными температурами, что позволит повысить эффективность разделения газовых смесей с минимальными энергетическими затратами. The claimed invention is aimed at solving the problem of expanding the possibility of separation of various gas mixtures into components, the full use of heat and cold released during cooling during gasification of liquefied components with obtaining a high degree of energy conversion with different temperatures, which will improve the efficiency of separation of gas mixtures with minimal energy costs.
Поставленная задача решается тем, что комбинированная система для разделения газовых смесей и энергопреобразования, содержащая криогенную машину Стирлинга, ректификационную колонну, теплообменник для вымораживания влаги и углекислоты, теплоизолированную емкость для жидкого азота, насос высокого давления, трубопроводы жидкого и газообразного азота и устройство преобразования энергии газообразного азота, согласно изобретению, содержит тепловой насос Стирлинга и двигатель Стирлинга, охлаждаемый жидким азотом, установленные с криогенной машиной Стирлинга в одном корпусе и имеющие общий шток с гидроцилиндром и пневмоцилиндром, и дополнительно содержит в качестве устройства преобразования разности энергии тепла и жидкого азота, по крайней мере, один двигатель Стирлинга. При этом криогенная машина и тепловой насос соединены рекуператором, а тепловой насос с двигателем - рекуператором с тепловым аккумулятором.  The problem is solved in that a combined system for separating gas mixtures and energy conversion, containing a cryogenic Stirling machine, a distillation column, a heat exchanger for freezing moisture and carbon dioxide, a heat-insulated container for liquid nitrogen, a high pressure pump, pipelines of liquid and gaseous nitrogen and a device for converting gaseous energy nitrogen, according to the invention, contains a Stirling heat pump and a Stirling engine cooled by liquid nitrogen, installed with a cryogen hydrochloric Stirling machine in a single housing and having a common shaft with a hydraulic cylinder and air cylinder, and further comprises a heat energy converting apparatus and the difference in liquid nitrogen, at least one Stirling engine. In this case, the cryogenic machine and the heat pump are connected by a heat exchanger, and the heat pump with the engine is connected by a heat exchanger with a heat accumulator.
Введение в состав комбинированной системы теплового насоса Стирлинга позволяет собрать всю тепловую энергию, выделяемую при охлаждении газовых смесей, а двигатель Стирлинга, использующий это тепло и охлаждаемый жидким азотом, вырабатывает энергию для работы всей системы совместно с гидроцилиндром и пневмоцилиндром, использующим энергию газообразного азота. The introduction of the Stirling heat pump into the combined system allows you to collect all the thermal energy released during the cooling of gas mixtures, and the Stirling engine, using this heat and cooled by liquid nitrogen, generates energy for the entire system to work together a hydraulic cylinder and a pneumatic cylinder using nitrogen gas energy.
Дополнительный двигатель Стерлинга использует избыток жидкого азота и энергию теплового аккумулятора или дополнительный источник тепловой энергии для совершения полезной механической работы.  The optional Stirling engine uses excess liquid nitrogen and the energy of the heat accumulator or an additional source of thermal energy to perform useful mechanical work.
Сущность заявляемой комбинированной системы для разделения газовых смесей и энергопреобразования поясняется чертежом.  The essence of the inventive combined system for the separation of gas mixtures and energy conversion is illustrated in the drawing.

The combined system comprises a cryogenic Stirling machine 1, a Stirling heat pump 2 and a Stirling engine 3, having a common rod 4 with a hydraulic cylinder 5 and an air cylinder 6, installed in one housing (not shown in Fig.), While the cryogenic machine 1 and heat pump 2 are connected by a heat exchanger 7, and the heat pump 2 is connected to the engine 3 by a recuperator 8 with a heat accumulator 9, a distillation column 10, a gas mixture supply pipe 11, a heat exchanger 12 for freezing moisture, a heat exchanger 13 for freezing carbon dioxide, heat exchange Ennik 14 for liquefying gases with a temperature range of -110 ° C - -170 ° C, a chilled gas mixture pipe 15 with a pump 16, a pipe 17 with a heat-insulated container 18 of a liquefied gas mixture, a pipe 19 for supplying a liquefied gas mixture with a pump 20 to a distillation column 10, a pipe 21 and a thermally insulated container 22 for liquid oxygen, a pipe 23 and a high pressure pump 24 for supplying liquid oxygen to a heat exchanger 14, a supply pipe 25 oxygen gas to the consumer, pipelines 26 with thermally insulated containers 27, 28 for liquid gas components with a temperature of -l iO ° C - -170 ° С, pipeline 29 with thermally insulated containers 30 for liquid gas components with a temperature of -185 ° С - -191 ° С , pipeline 31 with a thermally insulated tank 32 for liquid nitrogen, pipeline 33 with a pump 34 for supplying liquid nitrogen to Stirling engines 3 and 35, pipeline 36 with liquid metal coolant for supplying energy to a heat accumulator 9, a power take-off shaft 37 to an electric generator 38, pipeline 39, the removal of gaseous nitrogen to the device for converting energy of gaseous nitrogen to the pneumatic cylinder 6, the pipeline 40 of the removal of gaseous nitrogen to the consumer, the pipeline 41 of the removal of gaseous components — hydrogen, neon, helium.
Комбинированная система для разделения газовых смесей и энергопреобразования работает следующим образом.  The combined system for the separation of gas mixtures and energy conversion works as follows.
От внешнего источника (на фиг. не показано) энергию подводят к гидроцилиндру 5, приводя в движение шток 4. Криогенная машина 1 откачивает тепловую энергию в рекуператор 6 из газовой смеси, поступающей по трубопроводу 11. Сжиженную газовую смесь по трубопроводу 17 сливают в теплоизолированную ёмкость 18. Тепловой насос 2 перекачивает тепловую энергию с температурой +60°С - +100°С из рекуператора 7 в рекуператор 8 с тепловым аккумулятором 9, повышая температуру до +550°С - +600°С.  From an external source (not shown in Fig.), Energy is supplied to the hydraulic cylinder 5, driving the rod 4. The cryogenic machine 1 pumps heat energy into the recuperator 6 from the gas mixture entering through the pipe 11. The liquefied gas mixture through the pipe 17 is poured into a heat-insulated tank 18. The heat pump 2 transfers heat energy with a temperature of + 60 ° С - + 100 ° С from the recuperator 7 to the recuperator 8 with heat accumulator 9, increasing the temperature to + 550 ° С - + 600 ° С.
Из теплоизолированной ёмкости 18 сжиженную газовую смесь по трубопроводу 19 насосом 20 подают в ректификационную колонну 10. Отделённый жидкий кислород по трубопроводу 21 поступает в теплоизолированную ёмкость 22 и по трубопроводу 23 насосом 24 высокого давления его подают в теплообменник 14, в котором сжижают составляющие газовой смеси с температурой кипения - 110°С - -170°С и их собирают по трубопроводам 26 в теплоизолированные ёмкости 27 и 28. По трубопроводу 25 газообразный кислород с температурой -110°С направляют в теплообменник 13 для вымораживания и сбора углекислого газа из газовой смеси. Нагретый до -70°С кислород направляют в теплообменник 12 для удаления влаги из поступающей в систему газовой смеси. Охлаждённую до -170°С газовую смесь насосом 16 по трубопроводу 15 подают на криогенную машину 1, где остальные составляющие при охлаждении до -200°С сжижаются. Не сжиженные, но охлаждённые до температуры -200°С, водород, гелий и неон по трубопроводу 41 направляют для дальнейшего технологического цикла. По трубопроводу 29 в теплоизолированную ёмкость 30 собирают отделяемые составляющие газовой смеси с температурой кипения -185°С - -191°С и направляют на утилизацию. По трубопроводу 31 в теплоизолирующую ёмкость 32 собирают жидкий азот и по трубопроводу 33 насосом 34 подают в систему охлаждения двигателей Стирлинга 3 и 35. При температуре жидкометаллического теплоносителя теплового аккумулятора 9 +600°С (873°К) и охлаждения жидким азотом -196°С (77°К) термический КПД двигателя 3 с внешним подводом и отводом тепла равен: From the insulated tank 18, the liquefied gas mixture is piped 19 to the distillation column through a pipe 19 10. The separated liquid oxygen through a pipe 21 enters a thermally insulated tank 22 and through a pipe 23 with a high pressure pump 24 it is fed to a heat exchanger 14, in which the components of the gas mixture are liquefied with a boiling point of 110 ° C to -170 ° C and collected through pipelines 26 into thermally insulated containers 27 and 28. Oxygen gas with a temperature of -110 ° C is sent through pipeline 25 to a heat exchanger 13 for freezing and collecting carbon dioxide from the gas mixture. Heated to -70 ° C, oxygen is sent to a heat exchanger 12 to remove moisture from the gas mixture entering the system. Cooled to -170 ° C, the gas mixture is pumped through a pipe 15 to a cryogenic machine 1, where the remaining components are liquefied when cooled to -200 ° C. Not liquefied, but cooled to a temperature of -200 ° C, hydrogen, helium and neon are sent through pipeline 41 for the further technological cycle. By pipeline 29, detachable components of the gas mixture with a boiling point of -185 ° C to -191 ° C are collected in a thermally insulated container 30 and sent for disposal. Liquid nitrogen is collected through pipeline 31 to a heat-insulating tank 32 and pump 33 is fed into a cooling system of Stirling engines 3 and 35 through a pipe 33. At a temperature of the liquid metal coolant of a heat accumulator of 9 + 600 ° C (873 ° K) and cooling with liquid nitrogen -196 ° C (77 ° K) thermal efficiency of the engine 3 with an external supply and removal of heat is equal to:
КПД = (Тна1 - ToM)/T„arp = (873 -77)/873 = 0,91.Efficiency = (T on1 - To M ) / T „arp = (873 -77) / 873 = 0.91.
Это значит, что 91% тепловой энергии переходит в механическую, а отводить необходимо только 9% подведённого тепла и оставшийся жидкий азот можно использовать в одном или нескольких дополнительных двигателях 35, а тепло для нагрева жидкометаллическим теплоносителем подводить по трубопроводам 36. Если его не будет хватать в тепловом аккумуляторе 9, то подводить от любого другого источника, например, воздуха в жарких регионах. При этом получаемая мощность и КПД будут ниже, но на воздушных теплообменниках сконденсируется большое количество находящейся в атмосфере воды. При использовании солнечного и геотермального тепла двигатели 35 комбинированной системы работают без вредных выбросов в атмосферу и не изменяют тепловой баланс Земли. This means that 91% of the thermal energy goes into mechanical energy, and it is necessary to remove only 9% of the supplied heat and the remaining liquid nitrogen can be used in one or several additional engines 35, and heat for heating with liquid metal coolant should be supplied through pipelines 36. If it is not enough in the heat accumulator 9, then it must be supplied from any other source, for example air in hot regions. At the same time, the resulting power and efficiency will be lower, but a large amount of water in the atmosphere is condensed on air heat exchangers. When using solar and geothermal heat, engines 35 of the combined system operate without harmful emissions into the atmosphere and do not alter the thermal balance of the Earth.
Нагретый в двигателях 3 и 35 газообразный азот по трубопроводу 39 направляют в пневмоцилиндр 6 двухступенчатого расширения азота для использования его энергии вместе с энергией двигателя 3, обеспечивая для работы комбинированной системы уменьшение её потребления извне. По трубопроводу 40 для утилизации остаточной энергии газообразный азот направляют через вал отвода мощности 37 на турбину (на схеме не показано) с электрогенератором 38. Газообразные кислород и азот, нагретые до требуемой температуры и смешанные в необходимой для дыхания пропорции, направляют в помещения больниц, предприятий и жилья.  Gaseous nitrogen heated in engines 3 and 35 is sent via line 39 to the pneumatic cylinder 6 of two-stage expansion of nitrogen to use its energy together with the energy of engine 3, providing for the operation of the combined system to reduce its external consumption. Through the pipeline 40 for utilization of residual energy, gaseous nitrogen is sent through a power removal shaft 37 to a turbine (not shown in the diagram) with an electric generator 38. Gaseous oxygen and nitrogen, heated to the required temperature and mixed in the proportion necessary for breathing, are sent to the premises of hospitals and enterprises and housing.
Представленная схема показывает общие принципы работы узлов заявляемой комбинированной системы и может быть перенаправлена и дополнена для выполнения специальных задач.  The presented scheme shows the general principles of operation of the nodes of the inventive combined system and can be redirected and supplemented to perform special tasks.
Таким образом, заявляемая комбинированная система для разделения газовых смесей и энергопреобразования позволила расширить диапазон разделения различных газовых смесей на составляющие и предоставила возможность утилизировать вредные составляющие, полностью использовать выделяемое при охлаждении тепло и холод при газификации сжиженных составляющих с получением КПД 91% преобразования энергии с разными температурами в механическую, открывая новые перспективы двигателям внешнего сгорания, и значительно повысить эффективность разделения газовых смесей, например, удаляя углекислый, угарньш газ и метан в угольных шахтах с минимальными энергетическими затратами. Thus, the inventive combined system for separation of gas mixtures and energy conversion allowed expanding the range of separation of various gas mixtures into components and made it possible to utilize harmful components, fully use the heat and cold released during cooling during gasification of liquefied components with an efficiency of 91% conversion of energy with different temperatures to mechanical, opening up new prospects for engines external combustion, and significantly increase the efficiency of separation of gas mixtures, for example, removing carbon dioxide, carbon monoxide There is gas and methane in coal mines with minimal energy costs.
