Embodiment
Below in conjunction with instantiation and accompanying drawing, the present invention will be further described.
The invention provides a kind of bus tail gas heat quantity utilized device, comprise electricity generating device and armrest heater, wherein electricity generating device comprises and produces equipment 16 with tail gas and be connected, for deriving the metal tube 13 of tail gas, metal tube 13 outer wall posts temperature difference electricity generation device, and temperature difference electricity generation device and storage battery 18 and diode 17 connect and compose charge circuit; Armrest heater comprises the offgas duct 1, tail gas containing box 9 and the handrail 10 that connect successively; Described offgas duct 1 is communicated with the metal tube 13 of electricity generating device, and described handrail 10 mutually hollow connects.
In the present embodiment, described temperature difference electricity generation device is semiconductor refrigerating sheet 15, and semiconductor refrigerating sheet 15 side and described metal tube 13 outer wall are close to, and opposite side is glued with metal water tank 14.Further preferred, in order to improve generating efficiency, can in the following ways: the copper material that metal tube 13 selects thermal conductivity good; Cross section is selected to be square metal tube 13; Metal tube 13 inwall is provided with projection.
Preferably, silencing apparatus 12 is provided with between described metal tube 13 and offgas duct 1.
Preferably, described tail gas containing box 9 is provided with 4 mouths, is connected respectively with offgas duct 1, downtake pipe 2, second exhaust pipe 3 and the 3rd outlet pipe 4; Wherein downtake pipe 2 is provided with solenoid valve 5, and is connected with handrail 10; Second exhaust pipe 3 is provided with manually operated valve 8; 3rd outlet pipe 4 is provided with safety valve 7.Described handrail 10 outer wall is provided with temperature transducer 6, and the switch of solenoid valve 5 is by the SC sigmal control of temperature transducer 6.
Preferred further, described handrail 10 is connected with public transport vehicle chassis 11, and the through hole of handrail 10 leads to ground.
Manually operated valve 8 can the exhaust flow of control flow check in handrail 10 indirectly, tail gas all can be discharged thus in summer simultaneously; When safety valve 7 can prevent in the winter time manually operated valve 8 be in closed condition and solenoid valve 5 due to handrail 10 temperature too high and automatically close time cause main exhaust to be obstructed and stop working; Temperature transducer 6 is used to the temperature experiencing handrail 10, when temperature is too high, feeds back to solenoid valve 5, and solenoid valve 5 cuts out automatically, prevents handrail 10 temperature too high and the situation of generation scald passenger; Described handrail 10 is all through hole with joint, chassis 11, and other position gases can not spill, and tail gas directly discharges over the ground, can make the fast drying of sleety weather road surface to a certain extent like this.
