Slot collects condensed water to the collecting pipe of cooling tower side, can return the 20%-30% waters of cooling tower evaporation capacity in this way.Cold coagulation liquid
Temperature gap between the temperature of plate 7 and cooling tower soaking filler top saturation Hot wet air heating is bigger, and the cold condensation of coagulation liquid plate 7 is full
It is stronger with the ability of Hot wet air heating, can return that cooling tower evaporation capacity is bigger, by increase cold wind take out for device 9 air demand or
Person reduces cold wind and takes out the recycling ratio for supplying the feed air temperature of device 9 that can improve cooling tower evaporation vapour quantity.
For a cooling water inflow 5000m3The induced cooling tower of/h is calculated, evaporation loss by 1.5% evaporation capacity
75m3/ h, using the recyclable condensed water 25%~50% of the water-saving recovery scheme of the utility model, recyclable condensed water 18.75m3/
H~37.5m3/h；It is calculated as run 5500 hours per year, then 1 year recyclable pure water is up to 10.3125 ten thousand m3~20.625 ten thousand
m3。
Cold wind is taken out makes cold coagulation liquid plate 7 satisfy with cooling tower soaking filler top by inhaling for device 9 for extraneous normal air
Kept for 8.5 ° -11 ° with the temperature gap of Hot wet air heating, with regard to condensed water 23%~25% can be recycled.If increase cold wind to take out for device 9
Air demand, and the cold air to being inputted carries out cooling processing, makes cold coagulation liquid plate 7 and cooling tower soaking filler top saturation
The temperature difference of Hot wet air heating is kept for 20 ° -32 °, then recycles the ratio of condensed water with regard to that can reach 46%~50%.This scheme is special
Not Shi Yongyu seawater cooling, the discharge of cigarette vapour and the pure fresh water of acquisition can be reduced, good life can be provided for power plant
Use water.In the above-mentioned technical solutions, it is crucial that cold coagulation liquid plate 7 and cold wind, which are taken out for device 9,.In order to more effectively this item be protected to create
New results, applicant supply the cooling tower condensation fog-dissipation collecting system of device and its composition by being taken out respectively to cold coagulation liquid plate 7, cold wind
Independent patent protection.
