Design requirement, low-temp recovery liquid reduces regeneration effect, causes water production in periodic mode to reduce, and low-temp recovery liquid also can increase simultaneously
The consumption of regeneration alkali liquor；The former water of low temperature can slow down the warm-up movement of ion, contacted with ions resin particle surfaces in the unit interval
Number of times reduces, and ion exchange probability reduces accordingly, is unfavorable for producing of chemical feed water.Improve former coolant-temperature gage, can accelerate
The motion of ion, the thickness of the outer moisture film of minimizing resin, beneficially the carrying out of exchange reaction, but, water temperature raises, resin pair
The adsorption strength of ion can reduce, and also can affect the life-span of resin, need to control former coolant-temperature gage at 20-40 DEG C.
Additionally, only 35% left/right rotation becomes electric energy in the gross calorific power of thermal power plant, and the energy of more than 60% is discharged into four
In the middle of all environment, wherein, the heat that recirculated water is taken away accounts for the overwhelming majority.The thermal efficiency of cycle in thermal power plant to be improved,
Should start with from UTILIZATION OF VESIDUAL HEAT IN, from root, reduce cold end loss.
In sum, there is presently no a kind of reasonable in design, utilize recirculated water backwater to promote former coolant-temperature gage, improve chemistry
Water controlling the water circulation efficiency and chemical water moisturizing temperature, chemical water moisturizing temperature improves the degree of supercooling that can reduce condenser, improves power plant
The open circulating water thermal power plant former water water source device of performance driving economy.
Utility model content
