The solution focuses on constructing a photocatalytic hydrogen production reaction driven by solar concentration as the light source. It includes a trough-type parabolic concentrator system, a solar tracking system, a control system, and an overall structural support frame. A trough concentrator with single-axis tracking functionality is used to achieve photocatalytic hydrogen production under specific concentration conditions. The photochemical reaction process is evaluated through product monitoring, measurement, and analysis.
Utilizes the concentrating characteristics of the parabolic surface to focus a large area of solar energy into a specific range, generating stronger light or converting it into heat, thereby improving solar energy utilization efficiency;
The tracking system can achieve automatic azimuth tracking, ensuring the system operates at maximum efficiency regardless of weak or strong light conditions;
The detection and control system employs a touchscreen and computer for human-machine interaction, providing real-time monitoring and management to ensure reliable and safe system operation;
Components such as the storage tank, circulation pump, and flow trough are carefully designed to meet the requirements for long-term outdoor use, ensuring stable product generation and collection;
The main frame is made of aluminum profiles, which are both aesthetically pleasing and reliable. It also features adjustment functions for altitude and azimuth angle tuning.
