Description

Technical Field

[0001] The invention relates to the field of oxygen-iodine chemical lasers, in particular to a hand-cranked flywheel-driven rotating plate type singlet oxygen generator. Background Art

[0002] Oxygen-iodine chemical lasers play a very important role in high-energy lasers due to their short wavelength, good beam quality, high chemical efficiency, and engineering amplification. Singlet oxygen is the energy storage material in oxygen-iodine chemical lasers, and the singlet oxygen generator is the core component of oxygen-iodine chemical lasers.

[0003] At present, the basic principle of preparing singlet oxygen is generally the gas-liquid reaction of chlorine and BHP solution. The rotating plate generator is a common singlet oxygen generator structure. However, the traditional rotating plate generator has the following disadvantages: 1. The rotating plate speed cannot be too fast, otherwise it will cause the liquid film to rupture; 2. The rotating plate must rotate in the direction of the airflow, and the gas and liquid cannot fully contact, otherwise it will cause the liquid film to rupture; 3. Since the reaction is an exothermic reaction, and the rotating plate can only rotate at a low speed, it is necessary to update the solution in the reactor in real time; 4. The accumulation of heat causes the water vapor concentration in the reactor to increase, and a water removal device must be added at the outlet, but this still cannot prevent the singlet oxygen from being quenched by water vapor in the process of flowing out of the container; 5. It must rely on external power drive. Summary of the invention

[0004] The object of the present invention is to provide a hand-cranked flywheel driven rotating plate type singlet oxygen generator, which can manually control the direction and speed of the multi-layer thin sheet rotating plate and improve the adsorption stability of the liquid film on the multi-layer thin sheet rotating plate.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A hand-cranked flywheel driven rotating plate type singlet oxygen generator comprises a low temperature resistant reaction container, a multi-layer thin sheet rotating plate, a heat exchanger, a gearbox and an energy storage flywheel, wherein the multi-layer thin sheet rotating plate is arranged in the low temperature resistant reaction container, and the multi-layer thin sheet rotating plate rotating shaft, the gearbox and the energy storage flywheel axle are connected in sequence, micrometer-level circular holes are evenly distributed on both sides of each thin sheet of the multi-layer thin sheet rotating plate, a driving rotating plate is coaxially arranged on the energy storage flywheel, and a hand crank handle is arranged on the driving rotating plate, the heat exchanger is arranged in the low temperature resistant reaction container and is located at the lower side of the multi-layer thin sheet rotating plate, an air inlet and a singlet oxygen outlet are arranged at the upper end of the low temperature resistant reaction container, and a BHP solution is filled in the lower half of the low temperature resistant reaction container.

[0007] The multi-layer sheet transfer plate comprises a plurality of sheets uniformly distributed along the circumferential direction, and micrometer-level circular holes are uniformly distributed on both sides of each sheet in a rectangular array.

[0008] The gearbox is a thermostatic gearbox.

[0009] The hand crank handle is arranged in the middle of the driving rotating plate, and a groove for winding a transmission belt is arranged on the outer circumferential surface of the driving rotating plate.

[0010] The heat exchanger is a heat exchange tube that is reciprocatingly bent and arranged on the lower side of the multi-layer thin-sheet rotating plate, and the tube openings at both ends of the heat exchange tube are arranged outside the low-temperature resistant reaction container.

[0011] The lower half of the low-temperature resistant reaction container is square, the upper half is arched, and the inner wall is made of high-strength glass fiber reinforced material.

[0012] The upper surface of the air inlet is horizontal, the lower surface forms an angle with the upper surface, and the inner wall is made of GH600 alloy material.

[0013] The side surface of the singlet oxygen outlet is an isosceles trapezoid, the outermost outlet is a trapezoidal upper base, and the inner wall is made of quartz material.

[0014] The advantages and positive effects of the present invention are:

[0015] 1. The present invention utilizes an energy storage flywheel to be driven by a hand crank, and adjusts the rotation speed of the multi-layer thin-sheet rotating plate through a gearbox, so that the direction and rotation speed of the multi-layer thin-sheet rotating plate can be manually controlled, thereby changing the generation rate of singlet oxygen gas and avoiding situations such as liquid film rupture caused by excessive rotation speed.

[0016] 2. The multi-layer thin sheet rotating plate of the present invention has micron-sized circular holes evenly distributed on both sides of each thin sheet, which can increase the tension of the solution on the rotating plate, so that the liquid film can be stably adsorbed on the rotating plate even at high rotation speeds in different rotation directions. The renewal speed of the liquid film is accelerated at high rotation speeds, which improves the heat dissipation rate of the rotating plate and can greatly reduce the water vapor content in the final gas. Therefore, there is no need for a BHP solution renewal device. In addition, the lower the liquid film temperature, the greater the tension, which can further improve the stability of the liquid film adsorption on the rotating plate at high rotation speeds.

[0017] 3. The present invention provides a driving rotating plate coaxially on the side of the energy storage flywheel away from the low-temperature resistant reaction container. The driving rotating plate can be provided with a transmission belt and connected to a driving device according to actual needs to realize automatic driving rotation, so that both manual driving mode and automatic driving mode can be selected, which is more flexible to use.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the multi-layer thin film rotating plate 2 includes a plurality of thin films evenly distributed along the circumferential direction, wherein a rotating shaft is provided in the middle thereof and is rotatably arranged in the low-temperature resistant reaction container 1, one end of the rotating shaft is connected to the output end of the gearbox 4, and the input end of the gearbox 4 is connected to the axle of the energy storage flywheel 5.

[0024] In this embodiment, the material of the multi-layer thin film rotating plate 2 is titanium alloy, each layer is 0.5 mm thick, and the interval between two adjacent layers is 2 mm. The surfaces of both sides of each layer are evenly distributed with circular holes with a diameter of 0.025 mm and a depth of 0.01 mm in a rectangular array with a spacing of 0.1 mm, which can increase the tension between the liquid film and the surface of the rotating plate. At high rotation speed, the liquid film can be stably adsorbed on both sides of the rotating plate.

[0025] In this embodiment, the gearbox 4 is a thermostatic gearbox, and the temperature inside the gearbox 4 is maintained at 25 degrees Celsius to prevent the lubricating oil from condensing at low temperatures, thereby ensuring normal transmission of the shaft. The thermostatic gearbox is a well-known technology in the art.

[0026] like Figure 1As shown, a driving rotating plate 501 is coaxially arranged on one side of the energy storage flywheel 5 away from the low temperature resistant reaction container 1, and the hand crank handle 9 is arranged in the middle of the driving rotating plate 501. A single person can drive the energy storage flywheel 5 to rotate by rotating the hand crank handle 9, and then drive the multi-layer sheet rotating plate 2 to rotate through the gearbox 4. In this embodiment, the energy storage flywheel 5 is a carbon fiber energy storage flywheel.

[0027] like Figure 1 As shown, the driving rotating plate 501 can also be connected to a driving device through a transmission belt 6, one end of the transmission belt 6 passes around the groove on the outer circumference of the driving rotating plate 501, and the other end passes around the driving pulley provided on the output shaft of the driving device. The driving device can be a diesel engine, a steam turbine, an electric motor, etc.

[0028] like Figure 1 As shown, the heat exchanger 3 is a heat exchange tube, which is reciprocatingly bent and arranged on the lower side of the multi-layer thin sheet rotating plate 2, and one side of the tube mouth extends to the outside of the low-temperature resistant reaction container 1 and is connected to the coolant input pipe, and the other side of the tube mouth extends to the outside of the low-temperature resistant reaction container 1 and is connected to the coolant output pipe. The heat exchanger 3 stabilizes the temperature of the BHP solution in the low-temperature resistant reaction container 1 at -25 degrees Celsius.

[0029] like Figure 1 As shown, in this embodiment, the lower half of the low-temperature resistant reaction vessel 1 is square and the upper half is arched. Its inner wall is made of high-strength glass fiber reinforced material, which can maintain high mechanical strength and good thermal insulation within a temperature difference of 50 degrees Celsius between the inside and outside. The upper surface of the air inlet 7 is horizontal, and the lower surface forms an angle of 30° with the upper surface. Its inner wall is made of GH600 alloy material, which can withstand corrosion from dry chlorine and alkaline solutions at the same time. The side of the singlet oxygen outlet 8 is an isosceles trapezoid, and the outermost outlet is the upper bottom of the trapezoid, and the angle between the two waists and the upper bottom is 100°. Its inner wall is made of quartz material, which can effectively reduce the quenching of singlet oxygen when it contacts the wall.

[0030] The working principle of the present invention is:

[0031] When the present invention is working, the lower half of the low-temperature resistant reaction container 1 is filled with BHP solution, and the coolant circulates inside the heat exchanger 3 at the bottom to stabilize the temperature of the BHP solution at -25 degrees Celsius. The energy storage flywheel 5 is rotated by a single person through a hand crank handle 9. After the single person drives the energy storage flywheel 5 to rotate, the gearbox 4 is used to adjust the multi-layer thin-sheet rotating plate 2 to a suitable speed. At this time, chlorine and helium diluted in a certain proportion are introduced through the air inlet 7, so that singlet oxygen gas can be stably generated at the singlet oxygen outlet 8.

[0032] The energy storage flywheel 5 is manually driven by a hand crank handle 9, and the speed of the multi-layer thin sheet rotating plate 2 is adjusted by the gearbox 4, so that the direction and speed of the multi-layer thin sheet rotating plate 2 can be manually controlled, thereby changing the generation rate of the singlet oxygen gas. In addition, micrometer-level circular holes are evenly distributed on both sides of each thin sheet of the multi-layer thin sheet rotating plate 2, which can increase the tension of the solution on the rotating plate, so that the liquid film can be stably adsorbed on the turntable at high speeds in different rotation directions. The renewal speed of the liquid film is accelerated at high speeds, which improves the heat dissipation rate of the turntable and can greatly reduce the water vapor content in the final gas. Therefore, there is no need for a BHP solution renewal device, and the lower the temperature of the liquid film, the greater the tension, which can further improve the stability of the liquid film adsorption on the turntable at high speeds. The whole device has a simple structure, is easy to operate, and can be driven by manpower.

[0033] In addition, the present invention provides a driving rotating plate 501 coaxially on the side of the energy storage flywheel 5 away from the low-temperature resistant reaction container 1. The driving rotating plate 501 can be sleeved with a transmission belt 6 according to actual needs and connected to the driving device to realize automatic driving rotation, which is more flexible to use.
