In this embodiment, the device further includes a PLC controller 23, where the pressure gauge 9, the first thermometer 10, the flow meter 11, the second thermometer 21, the dissolved oxygen meter 22, the first electric control valve 3 and the second electric control valve 6 are all connected to the PLC controller 23, and the PLC controller 23 receives signals of the pressure gauge 9, the first thermometer 10, the flow meter 11, the second thermometer 21, the dissolved oxygen meter 22, the first electric control valve 3 and the second electric control valve 6, and controls the opening degrees of the first electric control valve 3 and the second electric control valve 6 according to the signals of the pressure gauge 9, the first thermometer 10, the flow meter 11, the second thermometer 21 and the dissolved oxygen meter 22.
The reason for the high oxygen solubility of the condensed water is that: 1) The water for power plants is generally stored in a tank or a water tank, and the demineralized water is basically in an oxygen saturation state because the water surface of the tank or the water tank is not tightly sealed. When the unit needs water replenishment in normal operation, desalted water is directly replenished to the hot well through the storage tank or the water tank. The normal condition is that the oxygen dissolving rate of the supplemented desalted water is 6-8 mg/L, the temperature is 15-25 ℃, and the oxygen dissolving rate of the supplemented desalted water is higher when the temperature is lower. 2) The heat supply unit supplies industrial steam to the outside, and a large amount of water is required to be supplemented for the operation of the unit because the heat supply steam is not recovered; when the water supplementing quantity exceeds the atomizing limit of the water supplementing atomizing device of the condenser, the water supplementing is insufficiently atomized, and the condenser cannot remove a large amount of dissolved oxygen for supplementing desalted water through vacuum deoxidization. 3) When the unit is used for heating, condensing, back drawing and cylinder cutting, the steam inlet amount of the low-pressure cylinder is greatly reduced, the steam amount entering the condenser from the low-pressure cylinder is correspondingly reduced, but at the moment, circulating water is far enough to condensate the steam of the low-pressure cylinder when the circulating water is operated in a low-flow mode, the excessive cooling amount of the circulating water can also cause the supercooling degree of the condensed water to be large, and the oxygen dissolving amount of the condensed water is unqualified.
Working principle: heating steam bubbling device is arranged below the liquid level in the condenser hot well, heating steam enters the liquid level of the hot well to be upwards diffused through a steam nozzle of a distribution pipe after being regulated by temperature, pressure and flow, steam moves to the upper part through the nozzle and flows reversely with condensed water moving downwards, the condensed water is uniformly heated to be close to or reach the saturation temperature, dissolved gas in the condensed water of the hot well is separated out at the moment, and then the dissolved oxygen index of the condensed water can be reduced to be in a qualified range through vacuum deoxygenation of the condenser.
The working method comprises the following steps:
step 1: the unit normally operates, and dissolved oxygen at the outlet of the condensing pump 17 is unqualified: the liquid level of the thermal well 13 is normal, the condensing pump 17 is put into operation, the temperature of the second thermometer 21 meets the operation requirement of the fine treatment device 19, the fine treatment device 19 is put into operation, and the value of the dissolved oxygen meter 22 exceeds the standard; the condensed water deoxidizing device is not put into operation, and the valve I2, the electric regulating valve I3, the valve II 5 and the electric regulating valve II 6 are in a closed state.

Checking that the states of the pressure gauge 9, the first thermometer 10 and the flow meter 11 are normal; the valve I2 is opened, the opening degree (about 2 percent of the opening degree) of the electric regulating valve I3 is slightly opened, the time is about 10-20 minutes, and after the temperature of the thermometer I10 reaches the incoming steam temperature (the temperature is about 350 ℃) and the pressure of the pressure gauge 9 (about 0.05 MPa) is stable, the heating pipe is ended.
2) And the steam temperature, pressure and flow parameters of the steam outlet pipe 8 are regulated. Opening the second valve 5, and increasing the opening degree (about 50 percent) of the first electric regulating valve 3, and observing the pressure gauge 9, the first thermometer 10 and the flow meter 11 for a period of time, wherein the pressure gauge 9 is 1.25MPa, the first thermometer 10 is 350 ℃, and the flow meter 11 is 50t/h; if the pressure gauge 9 to 1.0MPa is required to be regulated, the temperature gauge I is 10 to 250 ℃, the flow meter 11 is 40t/h, the pressure of the pressure gauge 9 and the flow of the flow meter 11 are controlled by the opening degree of the electric regulating valve I3, and the temperature gauge I10 can be controlled by the opening degree of the electric regulating valve II 6. By slowly adjusting the first electric regulating valve 3 and the second electric regulating valve 6, the opening degree of the first electric regulating valve 3 is controlled to be 40%, the opening degree of the second electric regulating valve 6 is controlled to be 15%, at the moment, the pressure gauge 9 is 1.0MPa, the temperature gauge 10 is 250 ℃, and the flow gauge 11 is 40t/h.
3) The temperature and dissolved oxygen of the outlet tube 18 of the coagulation pump are regulated. The temperature control on the water outlet pipe 16 is regulated by controlling the first thermometer 10 and the flow meter 11 on the steam outlet pipe 8. Generally, the values of the second thermometer 21 are low under the condition that the values of the dissolved oxygen meter 22 are not qualified due to the high supercooling degree of the condensed water; generally, when the dissolved oxygen meter 22 is qualified, the value of the second thermometer 21 can meet the operation temperature requirement of the finishing device 19. When the second thermometer 21 on the water outlet pipe 16 is lower and the dissolved oxygen meter 22 on the condensate pump outlet pipe 18 exceeds the standard, the pressure of the pressure meter 9 and the flow of the flow meter 11 are required to be increased at the moment, and 2) the pressure of the pressure meter 9 and the flow of the flow meter 11 are repeatedly operated and increased; when the pressure of the pressure gauge 9 and the flow of the flow meter 11 reach new values after the pressure gauge is stabilized for a period of time, the value of the dissolved oxygen meter 22 is just the index qualified critical value, and the temperature value of the second temperature meter 21 at the moment is recorded, wherein the temperature is the lowest temperature value of the water outlet of the thermal well 13 for regulating the qualification of the dissolved oxygen meter 22.
Step 3: automatic operation deoxidizing device:

(2) The highest value of the dissolved oxygen meter 22 is the maximum critical value of qualified dissolved oxygen index at the outlet of the coagulation pump 17. (3) The pressure of the pressure gauge 9 and the flow of the flow meter 11 are controlled by the opening degree of the electric regulating valve I3, and the temperature of the temperature gauge I10 is controlled by the opening degree of the electric regulating valve II 6. (4) The control of the second thermometer 21 and the dissolved oxygen meter 22 is regulated by regulating the temperature of the first thermometer 10 and the flow of the flow meter 11 on the steam outlet pipe 8.
2) The PLC 23 receives signals of the pressure gauge 9, the first thermometer 10, the flow meter 11, the second thermometer 21, the dissolved oxygen meter 22, the electric regulating valve I3 and the electric regulating valve II 6, and controls the opening degrees of the electric regulating valve I3 and the electric regulating valve II 6 according to the signals of the pressure gauge 9, the first thermometer 10, the flow meter 11, the second thermometer 21 and the dissolved oxygen meter 22.
3) After the manual operation deoxidizing device is stable, the deoxidizing device is put into an automatic control mode.
Step 4: shutdown deoxidizing device:
1) The deoxygenation device is switched from an automatic control mode to a manual mode.
2) Slowly closing the opening of the first electric regulating valve 3 to 0%, and then sequentially closing the first valve 2, the second electric regulating valve 6 and the second valve 5, wherein the inspection deoxidizing device is free from abnormality, and the shutdown of the deoxidizing device is completed.
