[0002] In the photocatalysis equipment, voltage stability is very important for photocatalysis efficiency, and stable voltage helps to improve the separation efficiency of electron-hole pairs and reduce their recombination rate, thereby improving the photocatalysis efficiency. Moreover, unstable voltage may cause overvoltage, which may damage electrode materials or catalysts, and even cause safety accidents.

Since the catalyst prepared by this method has larger specific surface area, stronger visible light absorption capacity and higher electron-hole separation efficiency, the catalyst has strong catalytic degradation capacity for organic pollutants and strong photocatalytic decomposition water to produce hydrogen capacity under visible light irradiation. The catalyst is used for the photocatalytic degradation process of TCP and the photocatalytic decomposition water to produce hydrogen process.

The purple light lamp irradiates the photoanode, the photoanode is electrically connected with the cathode, and the photoanode and the cathode are located in the reactor.

[0005] However, there is a problem: if the voltage stabilizer of the scheme encounters too small voltage, the circuit will be disconnected. Utility model content

[0006] The utility model provides a voltage stabilizing device applied to photocatalysis equipment to solve the problem that the voltage stabilizer will cause the circuit to be disconnected if too small voltage is encountered.

[0007] The utility model provides a voltage stabilizing device for photocatalysis equipment, comprising:

[0008] A voltage stabilizer is used to stabilize the voltage of the photocatalytic device, the first end of the voltage stabilizer is electrically connected with the photoanode of the photocatalytic device, and the second end of the voltage stabilizer is electrically connected with the cathode of the photocatalytic device.

[0009] A supplementary power supply, a first end of the supplementary power supply is electrically connected with the photoanode of the photocatalyst, and a second end of the supplementary power supply is electrically connected with the second end of the photocatalyst through a change-over switch;

[0010] A voltage detection device is used to detect the voltage of the photocatalyst, and output a signal to the change-over switch when the voltage of the photocatalyst is detected to be lower than a set value, and the change-over switch switches the state to turn on the circuit between the supplementary power supply and the voltage stabilizer to provide a backup voltage.

[0011] The principle of the scheme is that when the operator operates the photocatalyst, the photoelectrode will produce electron transition, at this time, unstable current will be generated, and then the unstable current is stabilized after passing through the voltage stabilizer, so that the photocatalyst can stably carry out the reduction reaction. When the photoelectrode is blocked by impurities or the light is insufficient, the unstable voltage will be reduced until it is lower than the minimum value of the voltage stabilizer, which will make the voltage stabilizer unable to operate, so that the circuit is not connected. At this time, the operator needs to rotate the change-over switch to make the supplementary power supply access to the circuit, and the supplementary power supply provides a higher voltage, so that the input voltage can also be used for photocatalysis even if it is very low.

[0012] The beneficial effects of the scheme are that when the input voltage is too low, a new supplementary power supply is connected through the change-over switch to provide voltage, preventing the photocatalytic reaction from being interrupted and improving the reaction efficiency.

The voltage in the photocatalytic circuit becomes smaller, which is likely to be caused by the adhesion of impurities to the photoanode, resulting in incomplete photocatalytic reaction. When the photoanode occurs photocatalytic reaction due to the violet light, electron transition will occur at the photoanode, at this time, unstable current will be generated in the entire circuit. When the voltage in the circuit becomes smaller, the operator controls the rotation of the change-over switch at this time, so that the change-over switch connects the supplementary power supply, and at the same time, the reciprocating motor is powered on. The power-on of the reciprocating motor makes the circular scraper move reciprocally on the guide rail. The circular scraper and the photoanode are coaxially arranged, and the circular scraper can scrape off the impurities on the photoanode when moving, so as to ensure the photocatalytic efficiency of the photoanode. When the voltage exceeds the bearing range of the voltage stabilizer, the operator controls the rotation of the change-over switch, so that the supplementary power supply and the motor are disconnected, and the circular scraper also stops moving. The circular scraper is prevented from being scratched on the photoanode for a long time, so as to prevent the photoanode from being damaged.

[0014] Further, the voltage detection device comprises a voltmeter and a controller, the voltmeter is arranged near the photo-anode, and the voltmeter is electrically connected with the controller, and the controller is electrically connected with the change-over switch.

[0015] Further, the voltage detection device comprises a voltmeter and a controller, the voltmeter is arranged near the photo-anode, and the voltmeter is electrically connected with the controller, and the controller is electrically connected with the change-over switch.
