Bending compensation of the rotary motion by one section of U-shaped reserved air hose is faced upward, another section of reserved air hose compensates equipment by being bent and reversing
Horizontal rotation movement, both ends are non-interference.The system and traditional being a difference in that use air as heat carrier, air with
Place can obtain, and do not have to concern about disclosure and lose.
Air is compared as heat carrier and is not needed dehydration, system run all right for thermally conductive oil medium.It is led with existing
Hot oil medium groove type solar collecting system compares, each cycle heat exchange of this air heat-exchange system, and water temperature is made to improve 5 DEG C,
Although high-efficient not as good as conduction oil medium system in thermal-arrest heat transfer efficiency, on system operation energy consumption, the oil of heat-conducting oil system
Pump motor power is about as many as 5 times of air system centrifugal blower power, therefore, comprehensively considers medium heat-transfer efficiency and system certainly
After body consumption, it is known that heat-conducting oil system remains basically stable in final effect with air heat transfer system.And in the early stage cost, in
The COMPREHENSIVE CALCULATINGs such as phase maintenance cost, later period member replacing cost, air dielectric opto-thermal system cost are all far below thermally conductive oil medium,
More importantly realizing can source green and environment-friendly utilization.

System cost compares explanation.Evacuated collector tube employed in heat-conducting oil system, (separate unit needs two to about 5000 yuan of single cost
Root).Heat-conductive-oil high-temperature rotary joint needs four, about 700 yuan of each cost.Separate unit photo-thermal apparatus conduction oil used in amounts is paid about
3000 yuan.In addition, further including mid-term maintenance cost, i.e., a reduction treatment, fillingization need to be carried out to conduction oil within every 3 to five years
Additive is learned, to make up the conduction oil performance degradation as caused by longtime running.It is different according to actual items, at each conduction oil
Reason expense is differed at 10,000 to 50,000 yuan.Later period member replacing cost include replacement after rotary joint to service life, conduction oil it is whole
Body replacement cost etc., since the design service life of equipment is 25 years, the service life of rotary joint and conduction oil is below 20
Year, it at least needs to renew primary.Therefore, in fairly large project, this expense also should not be underestimated.The above expense is only
Object cost does not also include resulting human cost.
Air after air collector tube can also being heated is transferred to direct use occasion by vent hose, such as dry,
It takes dim.Review air dielectric collecting system, the cost of air collector tube is about 600 yuan single (separate unit needs two), whole system without
Conduction oil and rotary joint are needed, replaces conduction oil with air, medium sheet is as zero cost.Air draught hose can by itself
Retractility, can starting point rotary joint effect, and a part of vent hose as pipe-line system, one-time investment with it is thermally conductive
It is equally matched for the metallic conduit of oil system.In addition, air system can also evade the oil leak risk of heat-conducting oil system, Bu Huizao
At environmental pollution and economic loss.
Therefore, air dielectric groove type solar opto-thermal system according to the present invention, manufacturing process is simple, cheap,
It is not required to safeguard.It is mounted on solar thermal utilization place, the manpower and financial resources cost of plant maintenance can be effectively reduced.It can be in industrial or agricultural
It is promoted the use of in production, there is high cost performance.
