На чертеже показано устройство для перемещений жидкости по контуру циркуляции.The drawing shows a device for moving fluid along a circulation circuit.

Устройство содержит емкость .1, частично заполненную жидкостью,подъемный 2 и опускной 3 каналы, общий отводной канал 4, нагреватель 5 и холодильник 6.The device contains a container .1, partially filled with liquid, lifting 2 and lowering 3 channels, a common outlet channel 4, a heater 5 and a refrigerator 6.

Устройство работает следующим образом.The device operates as follows.

Емкость 1, предварительно заполненную жидкостью, нагревают с помощью нагревателя 5 до образования парожидкостной смеси. Под действием давления паров, образовавшихся над поверхностью жидкости, парожидкостная смесь поступает в нижний участок подъемного канала 2 и далее в верхний его участок, где жидкость, частично отделившись от паров, возвращается через опускной канал 3 в емкость 1, способствуя перемещению следующих порций парожйдкостной смеси в подъемный канал 2. Пары жидкости, отделившиеся в верхнем участке подъемного канала 2, поступают в общий отводной. 15 канал 4 и, конденсируясь в холодильнике б, возвращаются в емкость 1 через опускной канал 3. Далее цикл повторяется.The tank 1, pre-filled with liquid, is heated using a heater 5 to form a vapor-liquid mixture. Under the action of vapor pressure formed above the surface of the liquid, the vapor-liquid mixture enters the lower section of the lifting channel 2 and then to its upper section, where the liquid, partially separated from the vapor, returns through the lowering channel 3 to the tank 1, facilitating the movement of the following portions of the vapor-liquid mixture in lifting channel 2. Vapors of liquid, separated in the upper section of the lifting channel 2, enter a common outlet. 15 channel 4 and, condensing in the refrigerator b, return to the tank 1 through the lowering channel 3. Then the cycle repeats.

Упрощение устройства для перемещения жидкости достигается благодаря исключению из устройства контура циркуляции газа, поскольку для перемещения жидкости не требуется .присутствия растворенного в ней газа.The simplification of the device for moving the liquid is achieved by eliminating the gas circulation circuit from the device, since the presence of gas dissolved in it is not required for moving the liquid.

The invention relates to the pump-free movement of fluid in closed circuits and can be used, for example, in heat exchange systems, chemical technology machines, and the like. A device for moving a fluid along a circulation circuit, comprising a container, is known. partially filled with liquid, lifting and descending 1 channels, heater and refrigeration located respectively at the bottom and. the top of the tank. In a device known, a gas soluble in liquid l is used as the transporting agent. The disadvantage of this device is its complexity and the need to use special gas-liquid mixtures. The purpose of the invention is to simplify the device. This goal is achieved by the fact that in a device for moving a fluid along a circulation loop containing a container partially filled with liquid, lifting and lowering channels, a heater and a cooler placed respectively in the lower and upper parts of the tank, the lower sections of the lifting and lowering channels under the liquid level, their upper sections are combined into a common outlet channel equipped with a refrigerator, while the immersion depth of the lower section of the lifting channel is shorter than that of the lowering and lifting channels, and op determined by the ratio of 1.27 V 7 h 7 O, D-2, where h is the depth of immersion in the liquid of the lower portion of the lifting channel; V is the total volume of sections of the lifting and lowering channels located above the liquid level; D is the internal diameter of the tank. The drawing shows a device for moving a fluid around a circuit. The device contains a capacity .1, partially filled with liquid, lifting 2 and lowering 3 channels, a common bypass channel 4, a heater 5 and a refrigerator 6. The device operates as follows. The container 1, which is pre-filled with liquid, is heated with the help of heater 5 to form a vapor-liquid mixture. Under the action of the pressure of the vapors formed above the surface of the liquid, the vapor-liquid mixture enters the lower part of the lifting channel 2 and further to the upper part of it, where the liquid, partially separated from the vapor, returns through the descending channel 3 to the tank 1, facilitating the movement of the following portions of the steam mixture in lifting channel 2, liquid vapors separated in the upper part of lifting channel 2, enter the common discharge channel 4 and, condensing in refrigerator 6f, return to the tank 1 through the lowering channel 3. an op. The simplification of the device for moving a liquid is achieved due to the exclusion of the gas circulation loop from the device, since the presence of gas dissolved in it is not required to move the liquid.
