ParabolicTrough Solar Collector

Our parabolic trough solar collector is mainlyconstituted by the collector module, drive system and tracking system. Whilethe collector module includes the collector tube, reflective mirror and torquebox. With 6 m wide opening, 1.71m focal length, 12m length, 80% to 82%concentration ratio, and over 70% optical efficiency, the collector module canmeet the installation requirements of parabolic trough tube with a standardlength of 4060mm.

In order to meet the requirements of solar power technology and the needs of scientific research and experimental apparatus, we havecurrently developed five categories of solar collector, including the PTC12,PTC24, PTC48, PTC60 and PTC100 types.

1. PTC12 Parabolic Trough SolarCollector
This piece ofequipment is composed of a collector module, hydraulic workstation, trackingsystem, heat exchanger and heat-conducting oil tank for generation of steam. Itutilizes the TB40 torque box and RMAl-20 aluminum honeycomb reflective mirror.It has now been applied in the performance research of collector parts and dataacquisition of power plant systems.

4. Tracking System
Our parabolictrough solar collector adopts the single axis tracking system, which achieves ahigh tracking accuracy of up to ± 0.8 mrad.This hydraulic tracking system is constituted by a hydraulic cylinder, powerstation, and electronic control system. The hydraulic cylinder is able toachieve maximally 220°rotation of the trough collector. In addition, theelectronic control system mainly calculates the angle of the sun based on thesun’s running track, then measures the angle of the collector through thesensor, and further ensures high tracking accuracy by controlling the hydraulicvalve block.
