AI Technical Summary

Technical Problem

Existing heat pumps, when recovering waste heat from blast furnace slag flushing water, have difficulty effectively filtering suspended solids in the slag water, leading to equipment blockage, affecting normal operation, and preventing continuous and efficient heat recovery.

Method used

Large suspended solids are initially intercepted by the interception grid inside the interception box. Combined with a quartz sand filter and a precision filter, triple filtration is performed to intercept impurities such as slag and rust, ensuring the stable operation of the heat pump unit.

Benefits of technology

It achieves efficient interception of suspended solids in slag water, prevents equipment blockage, ensures stable operation of heat pumps, improves waste heat recovery efficiency, and meets heat utilization needs.
