the moisturizing of power plant passes through multichannel moisturizing main pipe 11, sprays the atomization through moisturizing bypass pipeline 12 terminal first nozzle 13, and first nozzle 13 is special deoxidization vacuum heating power and revolves the type nozzle, can make outside moisturizing fully atomized, ensures the mixture and the heat transfer effect of moisturizing and steam extraction. The principle of small flow and large quantity is adopted, and under the fixed pressure, the smaller the single nozzle is, the smaller the fog drop is, and the better the effect is. Mechanical rotary spraying is carried out to form fog drops, surface tension is reduced to create a 'gas-water separation' condition, and exhaust steam is fully utilized to heat the sprayed fog drops so that the sprayed fog drops reach a near saturation temperature as soon as possible. The vacuum negative pressure formed by the condenser and the non-condensed steam gathering channel formed in the condenser are used for gathering the separated oxygen, the condenser is pumped out by a vacuumizing device, and 80% -90% of gas in water can be removed by a vacuum thermal rotary spraying block (an initial deoxygenation block).
Bubbling steam is carried through multichannel steam delivery main pipe 21, carries out the nozzle injection through steam delivery bypass pipeline 22 terminal second nozzle 23, makes the moisturizing of preliminary deoxidization chunk and condenser condensate carry out the bubbling heating effect, because the rotatory type of vacuum heating power sprays the chunk (initial stage deoxidization chunk) in-process, sprays in the condenser, steam heating, and appear oxygen and converge and take out the back, still partial oxygen remains in the moisturizing, and partial oxygen has also been dissolved in the power plant system condensate. The reason is that the water supplement contacts with the water pipe in the cold area in the falling process to form certain supercooling, and further secondary oxygen dissolution is caused. Therefore, it is necessary to add a vacuum thermal rotary bubbling block (deep oxygen removal block) to the condenser hot well to eliminate the supercooling degree of the condensed water of the water replenishing machine and reduce the secondary dissolved oxygen.
