Photocatalytic hydrogen production device

Abstract

The invention relates to the technical field of photocatalytic hydrogen production equipment, and concretely relates to a photocatalytic hydrogen production device. The device comprises a reaction cylinder, a vacuum pump and a raw material detection mechanism, and the raw material detection mechanism is used for detecting the amount of raw materials in the reaction cylinder; and the raw material detection mechanism comprises a fixing box, a supporting plate, a supporting disc, a fixing plate, a guide rod, a compression spring, an inclined block, a baffle, an image sensor, an L-shaped supporting plate, a guide column, a check ring, a top spring, a first induction block and a telescopic rod, the bottom of the reaction cylinder is fixedly connected with the fixing box, and the supporting plate is fixedly connected with the outer surface of the fixing box. By arranging the raw material detection mechanism and the catalyst detection mechanism, the ratio of the raw materials to the catalyst in the reaction cylinder can be monitored in real time, so that the raw materials or the catalyst can be added in time, and normal reaction is ensured.

Description

technical field [0001] The invention relates to the technical field of photocatalytic hydrogen production equipment, in particular to a photocatalytic hydrogen production device. Background technique [0002] At present, 80% of the world's energy comes from fossil fuels, but due to their non-renewability and the CO 2 Greenhouse gases, such as greenhouse gases, have become the main factors affecting the human living environment. Therefore, it is necessary to develop clean, massive and sustainable new energy sources. Hydrogen energy is favored because of its high calorific value products and no pollution! The traditional way to obtain hydrogen is through electrolysis of water or a by-product of chemical production. However, its disadvantage is that these technologies themselves have huge energy consumption, the gains outweigh the losses, and the cost performance is not high; in the traditional hydrogen production system, photocatalysts, water and sacrificial agents are all ...

Problems solved by technology

However, its disadvantage is that these technologies themselves have huge energy consumption, the gains outweigh the losses, and the cost performance is not high; in the traditional hydrogen production system, photocatalysts, water and sacrificial agents are all essential raw materials, and when the reaction is carried out for a period of time After a period of time, the photocatalyst loses its activity with the continuous occurrence of side reactions, thereby interrupting the reaction. At this time, people need to add appropriate reagents by observing various indicators of the instrument; There are low problems, resulting in photocatalytic hydrogen production is still in the experimental stage and cannot be industrialized
