Description

j Изобретение относитс  к области криоген|ной техники.j The invention relates to the field of cryogenic technology.

j Известны трубопроводы дл  криогенных (жидкостей, состо щие из коаксиальных труб |с теплоизол цией между ними..j Known pipelines for cryogenic (liquids, consisting of coaxial pipes | with thermal insulation between them ..

I Недостатком известного трубопровода  в .-легс  двухфазность потока, обусловленна  теплопритоком к жидкости, вызывающим ее испарение. Наличие газообразной фазы в потоке приводит к большим потер м напора и к необходимости установки сепараторов дл  сброса паров.I The disadvantage of the known pipeline.-Legss two-phase flow, due to the heat leakage to the liquid, causing its evaporation. The presence of a gaseous phase in the flow leads to large head losses and the need to install separators to discharge the vapor.

Целью ийобр-етени   вл етс  эвакуаци  Iгазообразной фа-зь из потока. I Это .достигаетс  тем, что внутренн   тру|ба вь/.ас кона иа пористого материала с от- iкpыты ;и пор.-, -и, а между ней и наружной |Тру6ой /ста ;овг;е1тп дополнительна  труба. 1 iioo6pei «зние по сн етс  чертежом. Трубопровод включает внутреннюю трубу лш nopncTOixi материала с открытыми пора:м:л , например из спеченного металлического inopi шка металлокерамики), наружную трубу и ;:1,с;пог1к;1тел--аую трубу 3 с вакуумной теп .-оизол цтйй между наружной и дополнитель;ной трубами. На подающем конце внутренней трубы установлен насос 4 дл  подачи жидKocTi; , а приемный конец допопнительной тру|бы присоединен к системе сброса паров 5. Приток тепла к трубе извне вызывает нсiпарение транспортируе ч ой жидкости в ее поipax . При этом весь теплоприток со|общение жидкости теплоты испарени , и, образом, внутрь трубы 1 теплоприток не проникает, что исключает возможность возникновени  двухфазного потока. Кроме тО го, холодные пары, проход щие в пространст ве между трубами 1 и 3,охлаждаюттрубу 3, снижа  таким образом приток тепла и поте|ри криогенной жидкости. Ф о р М у ла изобретени  Трубопровод дл  криогенных жидкостей, I выполненный в виде коаксиально расположенных труб с теплоизол цией между ними, ;отл и чающийс  тем, что, с целью эвакуации газообразной фазы из пото-, ка, внутренн   труба выполнена из пористого материала с открытыми порами, а между ней и наружной трубой установлена дополнительна  труба.The goal of a battery is to evacuate an I-gas phase from a stream. I This is achieved by the fact that the inner pipe of the end of the porous material with openings, and por-, –and, and between it and the outside | Trout / post; ovig; e1tp is an additional pipe. 1 iioo6pei Know the drawing. The pipeline includes the inner tube of the lop nopncTOixi material with open pores: m: l, for example, from sintered metal inopi metal ceramics cabinet), the outer tube and;: 1, s; pogk; 1 body pipe 3 with vacuum heat-insulation between the outer and additional pipes; At the feed end of the inner pipe, a pump 4 is installed to supply liquid KocTi; and the receiving end of the additional pipe is connected to the vapor discharge system 5. Heat inflow to the pipe from the outside causes insufflation of the transported fluid into its port. At the same time, the entire heat influx is the co-flow of heat of evaporation of the liquid, and, thus, the heat influx does not penetrate inside the pipe 1, which excludes the possibility of a two-phase flow. In addition, cold vapors that pass through the space between pipes 1 and 3 cool pipe 3, thereby reducing the influx of heat and loss of cryogenic liquid. FACTORY OF THE INVENTION A pipeline for cryogenic liquids, I made in the form of coaxially arranged pipes with thermal insulation between them, and distinguished by the fact that, in order to evacuate the gaseous phase from the stream, the inner pipe is made of porous material with open pores, and between it and the outer tube is installed an additional tube.
