Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogen preparation, in particular to a photocatalytic hydrogen production device. Background Art
[0002] The usual single substance form of hydrogen is hydrogen gas, which is a colorless, tasteless, odorless, highly flammable gas composed of diatomic molecules. Hydrogen gas is the lightest gas. Photocatalytic oxidation degradation of organic matter belongs to the reaction of reducing energy barrier. The △G of this kind of reaction is less than 0, and the reaction process is irreversible. In this kind of reaction, active groups such as O2-, HO2, OH·, and H+ are generated under the action of photocatalyst. The decomposition of water to generate H2 and O2 is a high energy barrier reaction. The △G of this kind of reaction is greater than 0 (△G=237kJ / mo1). This kind of reaction converts light energy into chemical energy.
[0003] In the existing photocatalytic hydrogen production equipment, when preparing hydrogen, as the illumination time increases, the temperature inside the test tube will gradually increase and cause the pure water to completely evaporate, making it difficult to ensure the quality and efficiency of the hydrogen preparation work. The existing technology directly dissipates heat through a fan, which drives the wind to blow towards the reaction tank. The heat dissipation time is long, resulting in low heat dissipation efficiency and slow temperature drop, which in turn affects the efficiency of the hydrogen preparation work and lacks certain practicality.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0028] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0029] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] In the related technology, the existing photocatalytic hydrogen production device does not have a good heat dissipation function and can generally only cool the reaction tank by blowing a fan. During use, the reaction tank cannot be cooled quickly, the cooling efficiency is low, and it has certain limitations.
[0031] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a photocatalytic hydrogen production device. When the reaction tank needs to be cooled, it is only necessary to turn on the water pump 26. By passing water into the interior of the box body 11 through the cooling pipe 23, the heat can be absorbed to complete the cooling, which is more convenient and quick, and improves the cooling efficiency of the device.
[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0033] Combination Figure 1-Figure 4 The embodiment of the present application provides a photocatalytic hydrogen production device, including a main body component 1; the main body component 1 includes: a box body 11 with a sealing cover 12 hinged on the top, and an irradiation lamp is arranged inside the box body 11, a reaction tank 13 is arranged inside the box body 11, and a threaded cover is arranged on the top, and a gas pipe 14 is inserted into the reaction tank 13. A cooling component 2 is arranged on the box body 11, and the cooling component 2 includes: a fan 21 is arranged on the box body 11, a vent 22 is opened on the box body 11, a mounting plate 25 is fixedly connected to the outside of the box body 11, a shell 24 is fixedly connected to the outside of the mounting plate 25, a water pump 26 is fixedly connected to the mounting plate 25, and the input end is inserted into the shell 24, one end of the cooling pipe 23 is flange-connected to the output end of the water pump 26, and the other end passes through the box body 11 and is connected to the shell 24.
[0034] When ready for use, place the box 11 in the designated position, open the sealing cover 12, then open the threaded cover on the top of the reaction tank 13, put the catalyst and pure water into the reaction tank 13, then turn on the irradiation lamp inside the box 11 to simulate the light source to irradiate the reaction tank 13 for catalysis, then the hydrogen is discharged through the gas pipe 14, and the operator collects the hydrogen. When the temperature of the reaction tank 13 rises, the operator connects the power supply of the water pump 26 on the top of the mounting plate 25 and turns on the water pump 26. The water pump 26 draws the water inside the shell 24 into the cooling pipe 23, and the heat inside the box 11 is absorbed and cooled through the cooling pipe 23. One side of the shell 24 is not closed, and it is naturally cooled by heat transfer from the external temperature, and the water inside the shell 24 is cooled to improve the cooling stability of the cooling pipe 23. Then the operator connects the power supply of the fan 21 and turns on the fan 21. The fan 21 blows the cooled air to the reaction tank 13 to further cool it down, and then the air is discharged through the vent 22, thereby improving the cooling efficiency of the device.
[0035] Specifically, the mounting plate 25 and the box body 11 , and the mounting plate 25 and the shell 24 are all fixed by welding.
[0036] In some embodiments, a filter plate 5 is provided inside the shell 24. When the operator adds water to the shell 24, the water is filtered through the filter plate 5 to prevent the water from carrying impurities such as gravel, which may cause the cooling pipe 23 to be blocked during use, thereby causing the device to be unable to be used normally.
[0037] In some embodiments, a slider 6 is fixedly connected to the outer side of the filter plate 5, a slide groove is provided inside the shell 24, and the slider 6 is slidably connected to the slide groove of the shell 24. The operator can pull the filter plate 5 to drive the slider 6 to slide in the slide groove, so that the operator can slide the filter plate 5 out of the shell 24, thereby facilitating the cleaning of the filter plate 5 and impurities filtered out of the filter plate 5, thereby improving the work efficiency of the operator.
[0038] In some embodiments, an auxiliary component 3 is provided in the box body 11, and the auxiliary component 3 includes: a motor 31 fixedly connected to the inside of the box body 11; a threaded rod 32 fixedly connected to the output end of the motor 31; a placement plate 33 threadedly connected to the outside of the threaded rod 32; a telescopic rod 34 is provided in the box body 11, and its two ends are respectively fixedly connected to the inside of the box body 11 and the outside of the placement plate 33.
[0039] The operator connects the power supply of the motor 31 and turns on the motor 31. The output end of the motor 31 drives the threaded rod 32 to rotate. Under the limit of the telescopic rod 34, the rotation of the threaded rod 32 drives the placement plate 33 to move upward at the same time, and drives the telescopic rod 34 to move up and down at the same time, so that the placement plate 33 drives the reaction tank 13 to move upward, which is convenient for the operator to place the catalyst in the reaction tank 13, thereby improving the convenience of the device.
[0040] Specifically, both ends of the telescopic rod 34 are fixed to the box body 11 and the placement plate 33 by welding.
[0041] In some embodiments, the length of the placement plate 33 is smaller than the inner length of the cooling tube 23 to prevent the placement plate 33 from accidentally touching the cooling tube 23 inside the box 11 when moving, thereby causing damage to the device.
[0042] In some embodiments, a protective pad 8 is fixedly connected to the box body 11. When the reaction tank 13 moves, the gas pipe 14 is driven to move at the same time. The protective pad 8 can protect the contact surface between the gas pipe 14 and the box body 11 to prevent the gas pipe 14 from rubbing against the box body 11 when moving and causing wear.
[0043] Specifically, the protective pad 8 is made of silicone and has an arc shape.
[0044] In some embodiments, a dustproof plate 4 is fixedly connected to the inside of the box 11. The dustproof plate 4 can filter the air blown in by the fan 21, and can also filter the air flowing into the vent 22 to prevent a large amount of dust from entering the device due to long-term use. The operator needs to clean it frequently, thereby reducing the operator's workload.
[0045] Specifically, the dustproof plate 4 is provided with a plurality of filter holes.
[0046] In some embodiments, a sealing sleeve 7 is fixedly connected to the outside of the shell 24, and the sealing sleeve 7 can seal the gap between the water pump 26 and the shell 24 to prevent water in the shell 24 from flowing out through the gap, resulting in a waste of water resources.
