Product Description

The parabolic trough solar high temperature collector is a high-efficiency line-focused solar collector, which is mainly composed of a reflector, a high-temperature collector tube, a support system, a tracking system, a transmission system and a control system. It has the advantages of mature technology, stable structure and easy control. The reflector rotates with the sunlight and directly converts solar energy into heat. Widely used in solar thermal power generation, industrial energy saving, heating and cooling, seawater desalination, drying, coal-fired boiler replacement, oil exploration and other energy-saving fields.

Reflector

Excellent substrate: the original film is made of ultra-clear float glass;

High reflectivity: silver plating ≥ 1500mg/㎡, reflectivity ≥ 94%;

High precision: mirror accuracy <2 mrad;

High mechanical strength: full tempering, high mechanical strength;

Five-layer anti-oxidation and anti-corrosion coating: the reflective silver layer is protected by a copper layer (deposition thickness ≥ 500mg/㎡), the copper layer is protected by an anti-oxidation protective layer to improve wear resistance and weather resistance of the equipment, and the green and environmental protection outer layer is Z anti-ultraviolet Protective coating for long life.

System Features:

◆ Heat collector tube: length 2000mm/4060mm, glass metal fusion sealing process, outer tube anti-reflection film

◆ Reflector: The original film is made of imported ultra-clear float glass, silver-plated 1500mg/㎡, reflectivity ≥ 94% ◆ Bracket: twisted tube type

◆ Drive mode: reducer/hydraulic

◆ Tracking method: time control

◆ Service life: ≥20 years

Solar high temperature heat collector tube

The high temperature collector tube is the core component of the trough collector. It mainly consists of a metal inner tube coated with a selective absorption film and a glass outer tube coated with an anti-reflection film. A vacuum is drawn between the glass outer tube and the metal inner tube to reduce heat loss and prevent oxidation of the selective absorber coating.

High temperature collector tube parameters:

◆ Collector length: 2000mm/4060mm

◆ Outer diameter of glass tube: 95mm/125mm

◆ Outer diameter of metal tube: 40mm/70mm

◆ High light transmittance: the outer cover glass tube is coated with AR antireflection film, and the sunlight transmittance is over 96%.

◆ High absorption rate: α≥95.5%

◆ High vacuum degree: ≤10-3mbar, 460℃ high temperature exhaust process

◆ Low heat loss: <117 W/m (350°C), <111 W/m (300°C), <69 W/m (250°C)

◆ Corrosion resistance: The inner pipe is made of DIN1.4541 steel, which has the advantages of corrosion resistance and high pressure resistance.

◆ Service life: ≥20 years

◆ Working temperature: the heat conduction medium can reach 380℃

◆ Working environment temperature: -40℃
