Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
As depicted in figs. 1 and 2：The present invention provides a kind of solar energy heating ventilating power generation system, including solar panel 1, storage
Electric installation 2, lighting device and smog dust collecting box 4, exhaust column 5, the first extractor fan that setting is sequentially connected with along wind direction
6th, smog dust collector 7, solar heat exchanger 8, exhaust duct 9, the second extractor fan 10 and chimney 11, wherein solar cell
Electric storage device 2 in parallel, lighting device, the first exhausting fill 6 and put and the second extractor fan 10 power output end of plate 1 respectively；Smog
Dust collecting box 4 is fixed in tunnel along tunnel trend；Smog dust collecting box 4 is pipeline closed at both ends, pipeline
Air admission hole 41 is provided with side wall, pipeline is arranged on the ground on the left of tunnel wagon flow direction, and such smog dust collecting box 4 can
It is collected with the dust preferably kicked up to hot-short on the left of tunnel, air admission hole 41 is in going out away from smog dust collecting box
Mouthful place, suction can reduce, so air admission hole 41 is using the outlet of smog dust collecting box as starting point, along between pipeline axial direction
Tapered into every the spacing of setting, and aperture becomes larger.The entrance point of exhaust column 5 connects each smog dust by flange respectively
The outlet of collecting box 4, the port of export accumulate main air draft, and the first extractor fan 6 is serially connected on main air draft；Smog dust collects
Case 7 is the cylinder case vertically installed, and its entrance point is tangentially disposed in cylinder upper box part, and lower end is gradually narrowed to axis to be gathered,
Form ash discharging hole, the closing of ash discharging hole normality, the upper end of cylinder case is fixed with blast pipe, and the inlet end of blast pipe straight down and is stretched
Enter in cylinder case；The outlet connection solar heat exchanger 8 of blast pipe, solar heat exchanger 8 is made up of more thermal-collecting tubes, to ensure
The intensity and heat-conducting effect of thermal-collecting tube, alkene pipe or bis-epoxy stainless steel tube, herein selection are bicyclic the optional polytetrafluoro of thermal-collecting tube
Oxygen stainless steel tube, to improve the gas of thermal-collecting tube by efficiency, thermal-collecting tube is by the way of more are arranged in parallel, the table of thermal-collecting tube
Face coats black chromium absorption film；To improve the utilization rate in soil, while using the reflective of thermal-collecting tube, solar panel is arranged on phase
Between adjacent thermal-collecting tube, solar panel 1 and thermal-collecting tube form entirety by support frame, and then solar panel 1 passes through solid
Dingan County is on domatic 13 that tunnel faces south；Simultaneously in order to improve the temperature of thermal-collecting tube, solar panel 1 and thermal-collecting tube it is upper
