Waste water have certain relative velocity, scale formation greatly reduces, owing to the waste water that need to evaporate is outside heat-transfer surface, thermal source
In heat-transfer surface, the circulation pump power solving existing frequently-used forced-circulation evaporator is big, power consumption is high, blade is easy to wear,
Pipeline length easily blocks, dispel the heat the series of problems such as big.But, in this patent there is seeping phenomenon in Condensed water collection chamber, as
Shown in Fig. 2, Fig. 3, Condensed water collection chamber is provided with water cavity closure plate 23 and is classified as multiple region (in Fig. 2 being 4),
Between water cavity closure plate 23, the water under region tube bank 13 condensation enters hollow axle, due to hollow axle by discharge outlet 24
It is provided with multiple discharge outlet (such as discharge outlet 25 in Fig. 2, Fig. 3) cold to get rid of other the interregional tube bank of Condensed water collection chamber
Water under Ning, the water flowing in hollow axle 17 is back to again in Condensed water collection chamber by discharge outlet 25, the most in time
Discharge outside system by hollow axle 17, only when the water level in Condensed water collection chamber is higher than hollow axle 17, condensed water just meeting
Discharged by hollow axle 17, hence lower than the tube bank of hollow axle 17 is full of water, thus greatly reduce steam condensation
Heat exchange area, unit are evaporated water greatly reduces, investment height, and equipment volume is big, runs power big.Therefore,
Vaporizer key issue with steam as thermal source does not gather control program for condensed water.
Summary of the invention
Technical problem: it is timely that the present invention provides a kind of condensed water that tube bank can flow to Condensed water collection chamber to pass through hollow axle
Outside discharge system, all tube banks are all not filled with condensed water, improve former technical units area water evaporates amount, reduce
Equipment investment, volume and run the drainage arrangement that the rotating tube bank vaporizer of power is new.
Technical scheme: the drainage arrangement that the rotating tube bank vaporizer of the present invention is new, including through rotating tube bank vaporizer
