Definitions
- This invention relates generally to energy separation devices, and more particularly to a scroll-type hot and cold gas separation device for separating a gas into a hot and cold gas stream using the Ranque-Hilsch effect.
- the temperature of the cold air flowing out of the vortex tube is about -20 ° C - 10 ° C by the vortex temperature separation effect, while the hot air flow
- the temperature can reach about 100 °C.
- George's explanation of temperature separation confused the concept of total temperature (stagnation temperature) and static temperature, he was questioned by the participating scientists.
- the phenomenon of hot and cold gas separation of vortex tubes was generally negated. This, in turn, led to the disruption of the full-rotation temperature separation effect and further investigation of the corresponding full flow tube device.
- the conventional vortex tube 10 is mainly composed of a nozzle 11 and a vortex generating chamber 12,
- the vortex popular inlet pipe (or temperature separation pipe) 13 the hot gas flow outlet 14, the cold air outlet 15 and the eddy current blocking reflow body 16 are formed.
- the vortex tube 10 injects compressed gas into the vortex generating chamber 12 through the nozzle 11 through a peripheral gas compressor (not shown in Fig.
- the vortex is injected
- the gas of the chamber 12 first expands and then enters the vortex inlet tube 13 in a tangential direction at a very high speed, traveling in the form of a spiral vortex; the traveling vortex is blocked by the eddy current blocking reversal body 16 before reaching the hot gas outlet 14 A portion of the gas will recirculate in the opposite direction in the form of a relatively small inner core vortex having a relatively small vortex diameter, and the unreturned gas will be discharged through the hot gas flow outlet 14, and the refluxed gas will be discharged through the cold gas flow outlet 15.
- the temperature of the outer vortex gas discharged through the hot gas flow outlet 14 is higher than the temperature of the inner core vortex gas discharged from the cold air outlet 15. Therefore, the airflow discharged through the hot airflow outlet 14 is referred to as a hot airflow, and the airflow discharged through the cold airflow outlet 15 is referred to as a cold airflow.
- hot gas flow and cold gas flow here should not be limited to be higher or lower than a certain absolute temperature value, but to compare the gases flowing out of the two gas flow outlets with each other. of. That is, the concepts of the terms "hot air flow” and "cold air flow” are clear and defined in the art.
- the airflow in the vortex tube device undergoes complex motion, the outer vortex gas moves toward the hot airflow outlet, and the inner core vortex gas moves toward the cold airflow outlet.
- the two vortices rotate in the same direction, and it is especially important that the two eddy currents Rotating at the same angular velocity, although there is a strong turbulent flow between the two vortex gases from the starting end to the end, the two eddy currents can be regarded as a whole from the viewpoint of rotational motion.
- Inner core eddy current is subject to the outer layer Eddy current, so the inner core eddy current is a passive vortex, and the outer eddy current is a driving vortex.
- the tangential linear velocity of the particles in the water vortex is inversely proportional to the eddy current radius. Therefore, when the particles in the water vortex move toward the outlet core, when the driving vortex radius is reduced to half, the tangential linear velocity of the particles along the vortex doubles, while the particles of the passive vortex that maintain a certain angular velocity of rotation follow the vortex.
- the tangential line speed is reduced by half. The particles that drive the vortex flow into the drain at a line speed four times faster than the particles of the passive vortex.
- the energy of motion is proportional to the square of the line speed.
- the kinetic energy of the particles of the passive vortex at the point where it flows into the drain is only 1/16 of the kinetic energy of the particles that drive the vortex into the drain.
- the popular traditional theory holds that in the vortex tube for hot and cold gas separation, the situation is similar to the above example, and the difference between the kinetic energy of the passive vortex gas and the driving vortex gas (total of 15/16 of the available kinetic energy) Where have you gone?
- This traditional theory holds that this is the key to exploring the principle of cold and hot gas separation in the Rank-Herzen effect, that is, the difference in kinetic energy will be transferred from the passive vortex at the inner core to the outer layer at the outer layer. Drive the vortex. In this way, the passive vortex gas becomes a cold airflow, and the driving vortex gas becomes a hot airflow!
- Their energy relationship is consistent with the law of conservation of heat and the law of conservation of energy.
- the diameter should not be too large, because it is generally accepted by those skilled in the art that in order to obtain the maximum temperature difference of the hot and cold air flow, the ratio of the length of the vortex inlet pipe 13 to the inner diameter (this ratio is usually also referred to simply as the aspect ratio of the vortex tube) should be Large, and it is further believed that the aspect ratio is preferably greater than 10, or even greater than 45. That is, in the state of the art in the art, it is generally recognized by the skilled person that the length of the vortex pop inlet pipe 13 should preferably be longer, and the vortex pop inside the pipe 13 under conditions capable of generating eddy currents and achieving inner core vortex reflow.
- the diameter should preferably be small.

- the compressed gas is injected into the vortex tube at a speed close to the speed of sound (for example, between 1/3 Mach and 7/8).
- the vortex tube is said to be able to separate the ultra-low temperature cold flow as low as -60 °C. .
- such a vortex tube device requires a large amount of compressed gas, so that the operation is harsh and the energy consumption is extremely high.
- the diameter of the vortex tube is too small, the vortex disk is too small, the time of the hot and cold gas separation process is too short, and the hot and cold gas separation function cannot be fully utilized;
- the eddy current blocking reflow pusher will generate a large amount of unhelpful turbulence at the tail of the vortex pop-in tube, reducing the efficiency of the device;
- the existing vortex tube device structure is not suitable for the manufacture of large scroll type hot and cold gas separation devices, such as a large-caliber, low-speed, large-caliber (such as a diameter of several hundred millimeters or more) scroll-type hot and cold gas separation device.
- the inventor of the present application recognizes two problems for a gas disk that is freely rotating in space.
- the centrifugal force or the rotational speed does not need to be large, as long as sufficient time is passed, the gas disk particles are elapsed for a certain period of time.
- the instantaneous velocity which is increased by the centrifugal force can have a sufficient influence on the gas pressure and thus have a sufficient influence on the gas temperature.
- the circumferential tangential linear velocity of the rotation does not need to be large, as long as the vortex disk particles
- the diameter of the rotating orbit is small enough that centrifugal forces can be generated that have sufficient effect on the gas pressure to have a sufficient effect on the gas temperature.
