Abstract
The invention discloses a direct air cooling system thermal state washing waste water drain-off system which solves the problem that an existing washing method is tedious in washing and consumes long washing time. The direct air cooling system thermal state washing waste water drain-off system comprises a tee joint (11) arranged on a condensation water pipeline. A first port of the tee joint (11) is communicated with a front section condensation water pipeline (4) communicated with a direct air cooling condenser (3). A sealing blind plate (13) is arranged in a position where a second port of the tee joint (11) is communicated with a back section condensation water pipeline (9). A third port of the tee joint (11) is communicated with the upper end of a temporary drain-off pipe (5). A temporary water tank (6) is arranged right under the temporary drain-off pipe (5). Water with the same height as a water tank partition plate (7) is stored in a storage area (A). The lower end of the temporary drain-off pipe (5) is arranged in water stored in the storage area (A). The direct air cooling system thermal state washing waste water drain-off system is simple in structure. Equipment and discharged wastewater can both be recycled.
