    Abstract:

    A coking plant extended many times, and its capacity of the cooling water system is not match with it, the consumption of new water is much more than that used by others in the same industry. The water system renovation is addressed for an extended coking plant. The installation of two 600 m3/h cooling towers and restoration the existing two cooling towers are to promote the cooling capacity so that the amount of discharge and feed could be reduced. At the same time, the pipe net for waste water reutilisation is installed, by which part of the waste water is reused as supplement water for quenching hot coke and the other was piped to ironworks for reuse. With the field test, the water consumption per ton of coke production is cut down from 9.03 m3 to 3.21 m3. And the annual water saving is more than 6×106 m3. Furthermore, the electric consumption is reduced by 2×106 kWh and about 3×106 yuan of annual running cost is saved.
