Description

Photocatalytic oxidation degradation of organic matter belongs to a reaction with a reduced energy barrier. In such reactions, under the action of a photocatalyst, active groups such as , , and are generated.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] As shown in the attached Figure 1 - Figure 8A device for photocatalytic hydrogen production as shown. Through the catalytic component arranged on the base 1, photons are absorbed, water is decomposed into oxygen and hydrogen ions, electrons participate in the reduction reaction of hydrogen ions, and combine with hydrogen ions to generate hydrogen. The hydrogen drifts upward, gathers through the gas gathering hood 3 and the supporting arc bracket 15, and is discharged and stored through the diversion valve 17. Through the electrode plate 8 at the bottom of the water filtering core cloth 5, electricity can be supplied to provide an electric field force, which promotes the directional movement of ions in the solution. The electric field force can help separate hydrogen ions and oxygen ions and prevent them from recombining. Through the electric field effect, the separation and migration of electrons and holes are promoted, and the efficiency of photocatalytic hydrogen production is improved. The water liquid in the liquid storage bucket 2 can boil and generate a certain amount of water vapor. The water vapor is shunted by each shunt plate 6 and drifts to the water filtering core cloth 5 to condense into smaller water droplets, and then can be photocatalyzed and undergo a decomposition reaction under the illumination conditions of the first enhanced illumination catalytic lamp 13 and the second enhanced illumination catalytic lamp 16, improving the catalytic hydrogen production efficiency and effect of the device, and the specific structure of the component is set as follows;

[0028] The catalytic component includes a liquid storage bucket 2 installed on the base 1 by bolts, and a gas gathering hood 3 for gas gathering is threadedly connected to the top of the liquid storage bucket 2;

[0029] A transparent cover 4 for light transmission is arranged in the middle of the liquid storage bucket 2, and a plurality of water filtering core cloths 5 are distributed on the outer side of the transparent cover 4, and shunt plates 6 for shunting are arranged on both sides of each water filtering core cloth 5;

[0030] Supporting bars 7 for lifting the water filtering core cloth 5 are arranged at the bottoms of a plurality of water filtering core cloths 5, electrode plates 8 are arranged at the bottoms of the supporting bars 7, a plurality of through holes 11 are formed through the plurality of electrode plates 8, reinforcing L plates 9 are installed on the outer sides of the plurality of supporting bars 7 and electrode plates 8 by bolts, extension cylinders 12 are installed at one ends of the plurality of electrode plates 8 by bolts, a supporting arc bracket 15 for support is installed on the top of the gas gathering hood 3 by bolts, and a plurality of second enhanced illumination catalytic lamps 16 for illumination are embedded in the supporting arc bracket 15;

[0031] The tops of multiple reinforcing L-shaped plates 9 are all installed with limit rings 10 through bolts. The limit rings 10 are located outside the flow dividing plate 6. A number of first enhanced light catalytic lamps 13 for lighting are embedded in the transparent cover 4. One side of each of the multiple flow dividing plates 6 is installed with a protective abutting plate 14 through bolts. A flow guiding valve 17 for guiding flow is arranged on one side of the surface of the air gathering hood 3. A limit box 18 is arranged on one side of the flow guiding valve 17. The limit box 18 is embedded in the air gathering hood 3 and is snap-connected to the air gathering hood 3. A water inlet pipe 19 for guiding flow is communicated with one end of the limit box 18. A clamping plate 20 is arranged at the other end of the limit box 18. The clamping plate 20 is located outside the air gathering hood 3. A water pump 21 is installed on the clamping plate 20 through bolts. One end of the water pump 21 is provided with a blade 22. The blade 22 is located in the middle of the limit box 18. And one end of the water pump 21 is provided with a first driving motor 23 for driving the blade 22 to rotate. The extension cylinder 12 is located at the bottom of the transparent cover 4 and is detachably connected to the transparent cover 4 through bolts. The flow dividing plate 6 is installed on the outside of the transparent cover 4 through bolts. A sealing strip for sealing is embedded between the liquid storage barrel 2 and the air gathering hood 3. A second driving motor 24 for driving the transparent cover 4 to rotate is embedded in the base 1. One side of the bottom of the reinforcing L-shaped plate 9 is slidably connected with a support ring rail 25. The support ring rail 25 is installed on the inner wall of the liquid storage barrel 2 through bolts. A cover plate 26 is arranged at the top of the transparent cover 4.

[0032] During use according to the above structure, the staff installs the device at a designated position. When performing photocatalytic hydrogen production, it is installed on the water pump 21 through a conduit. The first driving motor 23 drives the blade 22 to rotate, and the water source is transported to the liquid storage barrel 2 through the limit box 18 and the water inlet pipe 19. Then the catalyst is added to the liquid storage barrel 2. The second driving motor 24 drives the transparent cover 4, the flow dividing plate 6, the water filtering core cloth 5, the electrode plate 8 and the support bar 7 to rotate. Then when the electrode plate 8 rotates, it stirs the water and the catalyst in the liquid storage barrel 2, facilitating the full mixing of the water and the catalyst. At the same time, the water liquid of the mixed catalyst can also be heated through the electrode plate 8, improving the efficiency and hydrogen production amount of photocatalytic hydrogen production;

[0033] At the same time during catalysis, the light generated by the first enhanced light catalytic lamp 13 passes through the transparent cover 4 and irradiates on the water liquid.

The electrons participate in the reduction reaction of hydrogen ions and combine with hydrogen ions to generate hydrogen. The hydrogen drifts upward and is gathered by the air gathering hood 3 and the support arc-shaped support cover 15 and then discharged and stored through the flow guiding valve 17;

[0034] And through the electrode plates 8 at the bottoms of the respective water filtering core cloths 5, the generated hydrogen ions and oxygen ions are likely to recombine into water in the solution. Electrifying can provide an electric field force to promote the directional movement of ions in the solution. The electric field force can help separate hydrogen ions and oxygen ions to prevent them from recombining, and promote the separation and migration of electrons and holes through the action of the electric field, thereby improving the efficiency of photocatalytic hydrogen production.

[0035] Meanwhile, due to the resistance of water, the electricity emitted by the electrode plates 8 will generate heat, causing the water liquid in the liquid storage bucket 2 to boil and produce a certain amount of water vapor. The water vapor is shunted by each shunt plate 6 and drifts to the water filtering core cloth 5 to condense into smaller water droplets, and then can be photocatalyzed and undergo a decomposition reaction under the illumination conditions of the first enhanced illumination catalytic lamp 13 and the second enhanced illumination catalytic lamp 16, improving the catalytic hydrogen production efficiency and effect of the device.

[0036] Different from the prior art, the present application discloses a device for photocatalytic hydrogen production. Photons are absorbed to decompose water into oxygen and hydrogen ions. Electrons participate in the reduction reaction of hydrogen ions and combine with hydrogen ions to form hydrogen. The hydrogen drifts upward, gathers through the gas gathering hood 3 and the supporting arc bracket 15, and is discharged and stored through the diversion valve 17. Through the electrode plates 8 at the bottoms of the water filtering core cloths 5, electrifying can provide an electric field force to promote the directional movement of ions in the solution. The electric field force can help separate hydrogen ions and oxygen ions to prevent them from recombining, and promote the separation and migration of electrons and holes through the action of the electric field, improving the efficiency of photocatalytic hydrogen production. The water liquid in the liquid storage bucket 2 can boil and produce a certain amount of water vapor. The water vapor is shunted by each shunt plate 6 and drifts to the water filtering core cloth 5 to condense into smaller water droplets, and then can be photocatalyzed and undergo a decomposition reaction under the illumination conditions of the first enhanced illumination catalytic lamp 13 and the second enhanced illumination catalytic lamp 16, improving the catalytic hydrogen production efficiency and effect of the device.
