Specific embodiment
A kind of plate heat exchanger extraction pipeline hot washing device, scraper plate 1 pass through transfer line and connect liquid seal trough 2, the fluid-tight
2 liquid outlet of slot connects glycol circulation by transfer line and pumps 3 inlets, between the liquid seal trough 2 and glycol circulation pump 3
Ball valve 1 is arranged in export pipeline.The glycol circulation pumps 3 liquid outlets and passes through transfer line connecting plate type heat exchanger 6, described
Glycol circulation pumps the transfer line between 3 liquid outlets and plate heat exchanger 6 and ball valve 2 301 is arranged.The plate heat exchanger 6 goes out
It includes access one, access two that liquid mouth, which connects two route profilings,.The access one is that 6 liquid outlet of plate heat exchanger passes through perfusion tube
Line connects heating agent jacketed pipe 8, and ball valve three is arranged in the export pipeline between 6 liquid outlet of plate heat exchanger and heating agent jacketed pipe 8
601,8 other end of heating agent jacketed pipe connects glycol circulation pump 3, the heating agent jacketed pipe 8 and second two by transfer line
Ball valve 4 801 is arranged in transfer line between alcohol circulating pump 3.The access two is that plate heat exchanger 6 is connected by extraction pipeline 603
