Description of drawings
The structural principle block diagram of Fig. 1 the utility model air compressor cooling water heat recovery pre-heating system.
Embodiment
For technique scheme, now lift a preferred embodiment and also be specifically described in conjunction with diagram.Referring to Fig. 1, air compressor cooling water heat recovery pre-heating system of the present utility model mainly comprises air compressor 1, cooling water high-temperature conduit, cooling tower 2, cooling water low temperature water pipe, heat-exchange apparatus 3, second heat switching equipment 4, a heat storage tank 5, uses hot water zone 6, calorimeter 7, wherein.
Second heat switching equipment 4 also adopts board-like heat-exchange apparatus, between its and cooling water high-temperature conduit and cooling water low temperature return pipe in parallel with heat-exchange apparatus 3.The input end of the hot media channel of second heat switching equipment 4 is communicated with the cooling water high-temperature conduit by threeway Proportional valve 41, its output terminal and the pipeline communication that is positioned at the thermal medium output terminal of threeway Proportional valve 21 and a heat-exchange apparatus 3.The input end of the hot media channel of second heat switching equipment 4 directly is communicated with by threeway Proportional valve 41 outside second heat switching equipment 4 with output terminal.
