Description of drawings
Fig. 1 the utility model heat recovery system for air compressor structural principle block diagram.
Embodiment
For technique scheme, now lift a preferred embodiment and also be specifically described in conjunction with diagram.Referring to Fig. 1, heat recovery system for air compressor of the present utility model, it comprises oil circulation system that air compressor, air compressor carry, heat-exchange device 3, bypass circuit oil circuit 4, secondary cycle oil circuit 5, second heat switch 6, calorimeter 7, hot water suitable application region 8, wherein.
The oil circulation system that air compressor comprises compressor 10 and carries.This oil circulation system comprises compressor 10, Oil-gas Separation bucket 21, temperature control valve 22, oil cooler 23, oil strainer 24; Compressed machine 10 pressurized air that is mixed with oil out enters Oil-gas Separation bucket 21 separates oil gas, oil after the separation is through temperature control valve 22, when oil temperature was lower than the temperature value of setting, low temperature oil was back to oil strainer 24 through temperature control valve 22 and is back to after filtering compressor 10 and carries out next step circulation.When oil temperature is higher than the temperature value of setting, high temperature oil then through temperature control valve 22 flow through flow to oil strainer 24 after oil cooler 23 cools off and filter after backflow compressor 10 carry out next step circulation.
A heat-exchange device 3, an end of its hot media channel is communicated with the high temperature oil output terminal of temperature control valve 22, and the other end is communicated with the hot media channel of oil cooler 23; Its cold medium channel is communicated with secondary cycle oil circuit 5.Connecting tube between heat-exchange device 3 and oil cooler 23 is equipped with threeway Proportional valve 31, and bypass circuit oil circuit 4 one ends are communicated with threeway Proportional valve 31, and the other end is communicated with the input end of oil strainer 24.Pipeline between threeway Proportional valve 31 and heat-exchange device 3 is equipped with temperature transducer.When through the high temperature oil of temperature control valve 22 after a heat-exchange device 3 carries out heat exchange, temperature transducer detects the oil temperature after heat exchange, if oil temperature is lower than set temperature value, then the threeway Proportional valve is automatically opened low temperature oil is imported the backflow of bypass circuit oil circuit and be back to compressor 10 after oil strainer 24 filters; If oil temperature is higher than set temperature value, then high temperature oil is guided to oil cooler 23 through the threeway Proportional valve and further cools off, and high temperature oil refluxes to filter through oil strainer after further cooling and is back to compressor 10.
Second heat switch 6, its hot media channel is communicated with secondary cycle oil circuit 5, the cold medium channel of a heat-exchange device, the hot media channel of second heat switch and secondary cycle oil circuit 5 form the secondary cycle oil circuit 5 of a closed loop, be provided with oil circulating pump at this secondary cycle oil circuit 5 circulation power is provided.Cooling medium oil in the secondary cycle oil circuit is identical with the lubricant oil of air compressor self.The cold medium of second heat switch 6 is water, and its cold medium channel one end is communicated with cold water source, and the other end uses zone 8 to be communicated with to it for the hot water after heat exchange with hot water.Cold water feed-water end and hot water effluent's end at second heat switch 6 are separately installed with temperature transducer, at hot water effluent's end flowmeter are installed also.Calorimeter 7 can calculate the heat energy of saving by the flow number of temperature difference and the flowmeter statistics of collection cold water end and hot water end.
