Safety monitoring system in riser waste heat recovery process and monitoring method of safety monitoring system
2015
The invention discloses a safety monitoring system in a riser waste heat recovery process and a monitoring method of the safety monitoring system. The system comprises a plurality of risers provided with jacket cylinders and a plurality of riser control units correspondingly connected with the risers, wherein heat obtaining pipe groups are arranged in the jacket cylinders, upper and lower parts of the heat obtaining pipe groups are communicated with a water inlet pipe and a water outlet pipe respectively; each riser control unit comprises a signal difference sensor, the signal difference sensors are arranged in the jacket cylinders and detect work parameters in the riser jacket cylinders with the signal difference sensors, when the work parameters change, an upper computer sends cut-off instructions to control valves, the upper computer sends information riser identification codes and work parameters to a service provider server, a service provider changes the risers corresponding to riser information according to the information received by the service provider server, an upper computer actuator sends instructions to the corresponding control valves to enable the control valves to be opened, and the changed risers are used.
