Description of drawings
Fig. 1 has disclosed the structure chart according to the enclosed condensed water reclaimer of an embodiment of the present utility model.
The specific embodiment
Enclosed condensed water reclaimer of the present utility model has changed is used to that thinking is arranged, and is not that the low grade heat energy that will be recovered to uses as direct energy source, but as the preheating means than the GOOD TASTE energy.The pre-heat energy of these heats as boiler replenishing water used, make these heats enter smoothly in the energy resource system of enterprise, its energy-saving effect is remarkable.
It is a important step in the steam circulation system that condensed water reclaims, and the quality that reclaims from the viewpoint condensed water of energy saving of system directly influences the steam therrmodynamic system must energy utilization rate, is mainly reflected in the following aspects:
Heating power is worth: condensed water has 20% left and right sides heat energy of steam, is equivalent to a system that does not reclaim condensed water, and the energy-saving potential that condensate system is transformed is greater than other links of therrmodynamic system.
Thermal balance: reclaim the condensed water waste heat and be used for heating soft water, can save boiler oil, in general, every rising 6 degree of feed temperature, but with regard to fuel saving 1%.Condensed water reclaims the minimizing that is conducive to boiler blowdown water, reduces the blowdown heat loss, improves boiler thermal output.
The utility model has adopted recycling mode---the boiler feedwater of condensed water the best.Condensation water recovery system is divided into two kinds of open type and encloseds.Open system is simple, small investment, but because inside is corrosive other and impurity, water temperature declines by a big margin, it is reasonable to can not show a candle to enclosed.
