AI Technical Summary
During the operation of existing steam heat recovery devices, impurities in the steam enter the water storage tank, rendering the liquid unusable and preventing the recovery of steam waste heat, thus increasing the power consumption of the steam equipment.
The system employs a recovery and filtration mechanism within the cylinder. Through the cooperation of a heat-conducting copper tube and a hollow tube, the liquid inside the cylinder is stirred to recover waste heat, and impurities are filtered out through a filter screen, achieving efficient recovery of steam waste heat and reuse of the liquid.
This achieves full recovery of steam waste heat and rapid heating of liquids, reducing turbine power consumption and improving the energy efficiency of steam equipment.
