Description

Technical Field

[0001] The present invention relates to the technical field of reaction devices, and in particular to a reaction device used for electro-optical conversion research. Background Art

[0002] Electro-optical conversion refers to the phenomenon of excitation and luminescence of ionized gas under the action of an electric field. When rare gases (such as neon, argon, xenon) or mixed gases (such as mercury vapor) are placed in a high-voltage electric field, the gas molecules are ionized by the impact of electrons accelerated by the electric field, generating free electrons and positive ions. After the high-energy electrons transition to the excited state, they release energy in the form of photons when returning to the ground state. The wavelength of the photons is determined by the type of gas and the energy level difference. Electro-optical conversion has particularly stringent requirements on the purity of the gas. The vacuum degree in the reaction vessel before filling with the reaction gas needs to be better than 5*10 -3 Pa, so the reaction device used for electro-optical conversion research needs to have excellent gas sealing.

[0003] Most traditional electro-optical conversion devices use a combined sealing method of flanges and sealing gaskets, with the air inlet and outlet pipes connected to the flanges. Because the reaction device is molded from quartz, once the pressure between the flange and the sealing gasket exceeds the upper limit of the strength that the quartz itself can withstand, it will cause the quartz container to break. If the pressure between the flange and the sealing gasket is too low, the gas sealing performance will be poor and it will not be able to withstand high air pressure. At the same time, the combined sealing structure itself is not very reliable in terms of gas sealing performance, and the cost of achieving a high level of sealing performance is high. The air inlet and outlet are distributed at both ends of the reaction device, which may also cause uneven distribution of gas pressure in the container. These problems not only seriously affect the efficiency of electro-optical conversion research, but also increase the maintenance cost and operational complexity of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a reaction device for electro-optical conversion research to solve the following technical problems:

[0015] In a further embodiment of the present invention, an adjustable bracket is provided at the bottom of the reaction vessel for fixing and supporting the reaction vessel, which can be fixed on different experimental platforms and the height of the reaction device can be adjusted through the adjustable structure to enable experiments to be conducted on different experimental platforms.

[0016] In a further embodiment of the present invention, the adjustable bracket includes a base and several groups of height-adjustable support mechanisms arranged on the base.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] This embodiment discloses a reaction device for electro-optical conversion research, and its overall composition diagram is shown in FIG. Figure 1 As shown, its main structure includes a reaction container 100 and an adjustable bracket 200.

[0029] The reaction container 100 is used to seal the experimental gas and conduct the electro-optical conversion experiment, and a water-cooling liquid can be introduced to control the heat of the reaction container 100 to prevent the temperature from being too high and causing the container to rupture.

[0030] The adjustable bracket 200 is used to fix and support the reaction container 100 and can be fixed on different experimental platforms. The height of the reaction device can be adjusted through the adjustable structure to enable experiments to be performed on different experimental platforms.

[0031] The structural diagram of the reaction vessel 100 is as follows: Figure 2 As shown, the reaction vessel 100 is mainly composed of an outer quartz tube 110, an inner quartz tube 120, a sealed quartz tube 130, an electrode anode and wire 141, an electrode cathode and wire 142, a water-cooling liquid inlet pipe 151, a water-cooling liquid outflow pipe 152, and a gas inlet and outlet pipe 160.

[0032] The outermost layer of the reaction container 100 is an outer quartz tube 110 , which mainly provides a circulation space for a water-cooling liquid to achieve the operation of dissipating heat and cooling the reaction container 100 by using the water-cooling liquid.

[0033] The inner quartz tube 120 formed inside the outer quartz tube 110 is used to provide an experimental space for the experimental gas.

[0034] The sealed quartz tubes 130 located at both ends of the outer quartz tube 110 can realize an integrated sealing operation of the electrode anode and wire 141 and the electrode cathode and wire 142 through the sealed quartz tubes 130, thereby effectively improving the overall airtightness of the device.

[0035] Both ends of the inner quartz tube 120 are directly connected to the sealed quartz tube 130 to ensure that the electrode anode and wire 141 and the electrode cathode and wire 142 can ionize the gas in the inner quartz tube 120 .

[0036] The water-cooling liquid inlet pipe 151 and the water-cooling liquid outlet pipe 152 connected to the outer quartz tube 110 provide a circulation path for using the water-cooling liquid for heat dissipation. After the water-cooling liquid inlet pipe 151 and the water-cooling liquid outlet pipe 152 are connected to the water cooling equipment, a water cooling cycle can be formed in the reaction vessel 100 to achieve heat dissipation for the inner quartz tube 120, thereby preventing the inner quartz tube 120 from being thermally cracked due to excessive temperature during the experiment.

[0037] The gas inlet and outlet pipe 160 passes through the outer quartz tube 110 and is connected to the inner quartz tube 120, thereby realizing the operations of vacuuming and filling the inner quartz tube 120. The gas inlet and outlet pipe 160 is set in the middle of the inner quartz tube 120, which also solves the problem of uneven gas pressure distribution in the tube.

[0038] During the experiment, first connect the water-cooling liquid inlet pipe 151 and the water-cooling liquid outlet pipe 152 to the water cooling equipment, connect the gas inlet and outlet pipe 160 to the gas pumping and distribution equipment, and connect the electrode anode and wire 141 and the electrode cathode and wire 142 to the power supply; then turn on the water cooling equipment to pre-cool the inner quartz tube 120; after that, use the gas pumping and distribution equipment to evacuate the inner quartz tube 120; when the vacuum degree reaches the experimental requirements, use the gas pumping and distribution equipment to fill the inner quartz tube 120 with experimental gas; when the air pressure in the inner quartz tube 120 reaches the experimental requirements, stop the gas pumping and distribution equipment, and turn on the power to carry out the electro-optical conversion experiment.

[0039] The structural diagram of the adjustable bracket 200 is shown in FIG. Figure 3 As shown, it mainly consists of a fastening ring 210, a fastening bolt and nut 220, an inner column 231, an outer column 232, a height-fixing bolt and nut 240, a base 250, and a base positioning hole 251.

[0040] The fastening clamp 210 is used to fix the reaction container 100 on the base 250 . It is in direct contact with the outer quartz tube 110 , has a certain elasticity, and can fit the cylindrical tube shape of the reaction container 100 well.

[0041] The inner column 231 is used to fix the reaction container 100 together with the fastening clamp 210, and the inner column 231 also plays a part in achieving height adjustment.

[0042] The fastening bolts and nuts 220 are used to connect and fix the fastening ring 210 and the inner column 231 to fix the reaction container 100; by adjusting the number of screws on the fastening bolts and nuts 220, the clamping strength of the reaction container 100 can be adjusted to prevent the outer quartz tube 110 from being crushed due to excessive strength.

[0043] The outer column 232 is located on the outer layer of the inner column 231 and is used to achieve height adjustment together with the inner column 231; the inner column 231 can slide up and down in the outer column 232, and there is a certain gap between the two.

[0044] The height-fixing bolt and nut 240 pass through the inner column 231 and the outer column 232 to fix the height; after adjusting the inner column 231 to the required height, the height-fixing bolt and nut 240 can be inserted into the hole on the inner column 231 and the nut can be tightened to achieve height fixing.

[0045] A base 250 is fixed below the outer column 232, and base positioning holes 251 are evenly distributed on the base 250. The base 250 can be fixed on the experimental platform through bolts and the base positioning holes 251. The evenly distributed base positioning holes 251 can also fix the adjustable bracket 200 on experimental platforms with different hole spacings to achieve application in different experimental platforms.

[0046] When adjusting the height, first remove the height-fixing bolt and nut 240 , adjust the inner column 231 to the required height, and then pass the height-fixing bolt and nut 240 through the inner column 231 and the outer column 232 and tighten them.

[0047] When fixing the base 250 , the base 250 and the entire reaction device are fixed by passing the bolts through the base positioning holes 251 and fixing them at the desired hole positions, thereby achieving a fixing operation of the base 250 and the entire reaction device.

[0048] The working principle of the present invention is:

[0049] The above-mentioned reaction device for electro-optical conversion research adopts an integrated sealing structure, which directly seals the electrode anode and the electrode cathode in the sealed quartz tube 130, solving the problems of unreliable sealing, high sealing cost and difficult operation of the traditional combined sealing structure; at the same time, the series ventilation method is changed to a parallel method of single-tube vacuuming and inflation through the gas inlet and outlet pipe 160 that passes through the outer quartz tube 110 and connects to the inner quartz tube 120. On the one hand, it solves the problem of the inevitable use of a combined sealing structure for series ventilation, and on the other hand, it also solves the problem of uneven gas pressure distribution in the series ventilation method.
