The side of flushing pipe 8 is connected with blow-off line 13.
11 external gas source of gas pipeline.
The utility model is further described below in conjunction with attached drawing：
When in heat transfer effect difference or periodically carrying out online backwashing to plate heat exchanger, outlet valve 7 is closed, opens water inlet
Control valve 9 and outlet water control valve 10, water is back to cooling water inlet from cooling water outlet, to the internal pipeline of plate heat exchanger 1
It is rinsed, after the completion of flushing, closes water inlet control valve 9 and outlet water control valve 10, open outlet valve 7, then turn off water outlet
Valve 7 is opened water inlet control valve 9 and outlet water control valve 10, is rinsed repeatedly several times, when necessary, opens air valve 12, properly increases flushing
Pressure in Shi Guandao, effect are more preferable.
