Пред; ожеина  установка дл  втОршшбго сжижени  газа мо жт быть использована в транспортных средствах, например в судах дл  транспортировани  сжиженных газов при низкой температуре и нормальном давлении, содержащих изотермические контейнеры (на чертеже не показаны), покрытью слоем теплоизол ции, причем часть испар ющегос  в процессе транспортировки сжиженного газа направл етс  после соответствующей обработки в камеру сгорани  силовой установки транспортного средства (на чертеже не показана) дл  привода последнего. Газообразное топшгоо в соответствии с существующими требовани ми к силовым установкам может составл ть только часть топлива, поэтому возникает необходимость вторичного сжижени  оставшейс  неиспользованной части испар ющегос  сжижеш{ого газа и возврата его в изотермические контейнеры. Prev; The unit for the liquefaction of gas can be used in vehicles, such as vessels for transporting liquefied gases at low temperature and normal pressure, containing isothermal containers (not shown), covered with a layer of thermal insulation, and some of it evaporating during transport liquefied gas is directed, after appropriate treatment, to the combustion chamber of the vehicle's propulsion system (not shown) to drive the latter. In accordance with the existing requirements for power plants, the gaseous top gas may comprise only a part of the fuel; therefore, it becomes necessary to liquefy the remaining unused part of the evaporating liquefied gas and return it to the isothermal containers.

Сущность изобретени  заключаетс  в том, что нагреваема  часть испарившегос  газа, направл е ш  дл  привода транспортного средства, предварительно , с неболыпими затраталтк энергии используетс  дл  охлаждени  и последующего вторичного сжижени  другой части испар1шщегос  газа, возвра щаемойв изотермические контейнеры.The essence of the invention is that the heated part of the vaporized gas, which is sent to drive the vehicle, is used for cooling and subsequent secondary liquefaction of another part of the evaporated gas returned in the isothermal containers.

Испар ющийс  в изотермических контейнерах газ собираетс  трубопроводом 1 отвода испар ющегос  газа и подаетс  к управл емому трехходовому клапану 2, где раздел етс  на два частичных потока, и один из них поступает по трубопроводу 3 к компрессору 4 и далее к теллообменш ку 5, вьшолненному по схеме противотоком и включающему в себ  предварительный охладитель 6, конденсатор 7 и вторичный охладитель 8. Далее этот поток через расширительный орган 9 и трубопровод 10 возвращаетс  в изотермические контейнеры или в один из них.The gas evaporating in isothermal containers is collected by pipeline 1 to evacuate the evaporating gas and is supplied to a three-way controlled valve 2, where it is divided into two partial streams, and one of them enters through pipeline 3 to compressor 4 and further to the countercurrent flow circuit comprising the pre-cooler 6, the condenser 7 and the secondary cooler 8. Then this flow through the expansion unit 9 and the pipeline 10 is returned to the isothermal containers or to one of them.

Второй поток испарившегос  газа по ответвл ющемус  трубопроводу 11 поступает во вторичный охладитель 8, далее в конденсатор 1, предварительный охладитель 6, к дополнительному компрессору 12 и затем по трубопроводу 13 в камеру сгорани  силовой установки транспортного средства . Количество протекающего через вторичный охладитель 8 газа второго потока регулируетс  трубопроводом 14 с перепускным клапаном. Компрессоры 4, 12 осзоцествл юг отсос испарившегос  газа из изотермических кошейперов.The second stream of vaporized gas through the branch pipe 11 enters the secondary cooler 8, then to the condenser 1, pre-cooler 6, to the auxiliary compressor 12 and then through the pipeline 13 to the combustion chamber of the vehicle power plant. The amount of the second stream gas flowing through the secondary cooler 8 is regulated by a pipe 14 with a bypass valve. Compressors 4, 12 oszotsestl South suction of evaporated gas from isothermal Kosheyperov.

Управление и регулирование установки осуществл етс  при помощи регул тора 15 скорости с датчиком давлени  газа на входе в компрессор 4, регул тора 16 давлеш1  с давлени  газа в изотермических контейнерах, управл ющего устройства 17 с датчиком давлени  газа после компрессора 4 и регул тора 18 уровн  сжиженного газаThe installation is controlled and regulated by means of a speed controller 15 with a gas pressure sensor at the compressor inlet 4, a pressure pressure controller 16 for the gas pressure in isothermal containers, a control device 17 for a gas pressure sensor downstream of compressor 4, and a liquefied gas level controller 18 gas

Трубопроводы 1 и 3 соединены пусковым трубопроводом 19 с теплообменником 20 обогреваемым посторо1шим истошиком тепла, например морской водой.The pipelines 1 and 3 are connected by the starting pipe 19 to the heat exchanger 20, which is heated by an exhausted heat source, for example, sea water.

Кроме Tofo, установка Снабжена регул тором 21с датчиком количества газа, поступающего от изотермических контейнеров, и регул тором 22 давлени  на выходе компрессора 4, работающим в зависимости от соотношеьш  количества газа в потоках, раздел емых клапаном 2.In addition to Tofo, the installation is equipped with a regulator 21c with a sensor for the amount of gas coming from insulated containers, and a regulator 22 for pressure at the outlet of compressor 4, which operates depending on the ratio of the amount of gas in the streams separated by valve 2.

Установка работает следующим образом.The installation works as follows.

Испарившийс  в изотермических контейнерах транспортного средства газ в количестве 0,2-0,35% от общего количества сжиженного газа в сутки раздел етс  трехходовым клапаном 2 на два потока в соотношении, управл емом вторичным сжижением , в часшости,, давлением конденсации вторично . сжижаемого газа, что peaJП зyeтc  управл ющим устройством 17.

The regulator 21 establishes a relationship between the total amount of gas evaporating in the isothermal collectors and the amount of gas sent for combustion as fuel.

Subsequently, after the heat exchanger 5 comes into operation, the flow of gas through the heat exchanger 20 is stopped.
