Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a system construction drawing of the present invention.
Embodiment
With reference to Fig. 1, a kind of residual heat of air compressor reclaiming system, the oil-way system of this air compressor is provided with the three-temperature sensor TP3 and the second flow control valve PV2, and compressed air line is provided with the 4th temperature transducer PT4.This residual heat of air compressor reclaiming system comprises the first heat exchanger H1, the second heat exchanger H2; The water outlet of the said first heat exchanger H1 is communicated with the water intake of the said second heat exchanger H2; Said pressurized air of discharging from air compressor is accomplished heat exchange with cooling water in the first heat exchanger H1; The oil-way system of said air compressor is accomplished heat exchange with cooling water in the said second heat exchanger H2; Said cooling water gets into from the water intake of the first heat exchanger H1, discharges from the water outlet of the said second heat exchanger H2, and intake pipe and outlet conduit are provided with water pump M1, M2.
The intake pipe upper edge water (flow) direction that connects the said first heat exchanger H1 water intake is disposed with the first temperature transducer PT1, first flow control valve PV1, the first solenoid valve Y1 (normally closed) and the first safety check F1; The outlet conduit upper edge water (flow) direction that connects the said second heat exchanger H2 water outlet is disposed with the second safety check F2 and the second temperature transducer PT2.
Outlet conduit after the intake pipe between said first flow control valve PV1, the first solenoid valve Y1 and the second safety check F2 is communicated with through the bypass water channel; Said bypass water channel is provided with the second solenoid valve Y2 (normally closed); The effect of bypass water channel is to open the back at the second solenoid valve Y2 to form the pipe network path, makes system water supply continuous.
Outlet conduit before the said second safety check F2 is provided with the pressure release branch road, and said pressure release branch road is provided with the 3rd solenoid valve Y3 (often opening), and the 3rd solenoid valve Y3 opens, and can lay down in the heat exchanger and press and water vapor.
Working procedure of the present invention is following:
1, system start-up gets into automatic running state, the second flow control valve PV2 auto-closing; Three-temperature sensor TP3 show value reaches certain value (as 70 degrees centigrade); The 3rd solenoid valve Y3 gets electric opening, and must electricly beat to such an extent that open behind the first solenoid valve Y1, and system goes out water running and shows.
2, in service, water is full, and first flow control valve PV1 breaks off, and water outlet stops, and the second solenoid valve Y2 gets electric back 5-10 second (fixed value), the first solenoid valve Y1, the 3rd solenoid valve Y3 outage, and water is completely shut down demonstration.
3, supply water when water level reduces once more, first flow control valve PV1 auto-closing, the 3rd solenoid valve Y3 get electric earlier, and the first solenoid valve Y1 gets electric 5-10 second (fixed value), second solenoid valve Y2 outage, and system goes out water running and shows.
4, air compressor in service is shut down, and the second flow control valve PV2 breaks off, and system gets into time-delay and shuts down (30-180 is adjustable second), not controlled by three-temperature sensor TP3 show value, but controlled by first flow control valve PV1, and autostop shows.
5, in the time-delay stopping process, air compressor starts once more, and the second flow control valve PV2 is closed, and time-delay stops, and operation shows automatically.
