Embodiment
Referring to Fig. 1, this device comprises:
Ion-exchanger 8, is equipped with ion exchange resin, for the harmful ion except anhydrating, makes and purifies waste water.
Hydrogenation unit 1, for adding hydrogen to purifying waste water, comprise the ball valve 110, magnetic valve 120, reducing valve 130, gas meter 140, the vacuum breaker 150 that are linked in sequence.
Gas liquid mixer 2, purifies waste water and hydrogen for mixing, and hydrogen is dissolved in and purify waste water, and makes hydrogeneous purifying waste water.
Palladium resin catalysis deoxygenator 4, is equipped with the ion exchange resin of the palladium doping of styrene-based-divinylbenzene co-polymer, for removing the hydrogeneous residual dissolved oxygen of purifying waste water, makes and is applicable to the water coolant that generator unit stator winding uses; Its top is furnished with vent valve 3, hydrogen, the oxygen of overflowing for discharging water.
Water tank 6, for storing water coolant, and supplies water to generator unit stator winding.
Dissolved oxygen controller 7, for detection of the oxygen level in water coolant, opens or cuts out according to Control for Oxygen Content hydrogenation unit 1.
The hydrogen outlet of described hydrogenation unit 1 connects the inlet mouth of gas liquid mixer 2, and the water outlet of described ion-exchanger 8 connects the water-in of gas liquid mixer 2, and the import of described palladium resin catalysis deoxygenator 4 connects the water outlet of gas liquid mixer 2.
This device is also provided with resin catcher 5, is arranged between catalytic deoxidation device 4, water tank 6, for catching the exchange resin molecule that is free on water.
The working process of this device:
In the time that dissolved oxygen controller 7 detects circulating cooling oxygen content in water higher than 20PPb, send control signal, open the magnetic valve 120 of hydrogenation unit 1, add hydrogen.Oxygen level is during lower than 10PPb, and shut electromagnetic valve 120, stops hydrogenation.
The deoxygenation principle of this device:
Hydrogen is added to the water, makes it occur to react as follows with the dissolved oxygen in water, reach the object of deoxygenation.
This principle is common practise, is that people easily expect, problem is, make above reaction occur, and hydrogen must be soluble in water, is ionic state, could react with dissolved oxygen ion, and hydrogen is a kind of light element, and its chemical bond is stronger, is difficult to soluble in water.
This device adopts the ion exchange resin of the palladium doping of styrene-based-divinylbenzene co-polymer, reaction occurs on the surface of metallic palladium bunch, hydrogen is attracted to metallic surface, H-H key is weakened, thus form can with the hydroperoxyl radical [H] with triplet state diradical oxygen [O-O] reaction that dissolves in water
By the catalysis of palladium resin, make the combination reaction of hydrogen and oxygen become easy.Can be by the Control for Oxygen Content of electric generator inner cooling water below 20PPb, the requirement conforming to current standards.
