When the gas volume in the air pipe 15 reaches a certain range, the pressure will increase, and the gas will impact the hollow ball 2 so that the hollow ball 2 will break away from the first circular hole 16. When After the gas pressure in the air pipe 15 is reduced, the hollow ball 2 will be reset under the tension of the elastic rope 22; the bubbles will reach the bottom of the horizontal plate 32 after flowing out from the first circular hole 16, and then some bubbles will flow out from the edge of the horizontal plate 32, and some bubbles will pass through the second circular hole 33 and be divided into several small bubbles by the second circular hole 33; when the stirring rod 19 rotates, it will drive the guide plate 4 to rotate together, and when the guide plate 4 rotates, it will drive the bubbles in the device to flow together and guide the flow trajectory of the bubbles, so that the bubbles on the edge of the inner wall of the device can move toward the center of the device, increasing the contact area between the bubbles and pentamethyl ethanol; when the pentamethyl ethanol vapor enters the exhaust port 13 After that, it will come into contact with the baffle 5, and then the pentamethylethanol vapor with a lower temperature will condense on the surface of the baffle 5 and flow along the surface of the baffle 5, and the pentamethylethanol liquid will return to the interior of the shell 1 and be reheated by the equipment; the pentamethylethanol vapor in the exhaust port 13 will be liquefied and will flow along the surface of the baffle 5 and reach the vertical rod 6, and then the pentamethylethanol liquid will drip back into the shell 1 along the vertical rod 6; when the pentamethylethanol is heated inside the shell 1, heat will be dissipated to the outside through the shell 1.
