Abstract
The utility model discloses a water complementing system of a deaerator. The water complementing system of the deaerator comprises a water drainage box, a water drainage pipe, a condenser, a condensat pump, a low-pressure heater, and a deaerator. The water drainage box, the water drainage pipe, the condenser, the condensat pump, the low-pressure heater, and the deaerator are connected in sequence through a pipeline. The water drainage box is communicated with a recycle-water pipeline. A demineralized water pipeline II is communicated with the water drainage box and a demineralized water pipeline I is communicated with the deaerator. A valve is arranged on the demineralized water pipeline I. Due to the fact that the demineralized water pipeline II is communicated with the water drainage box, the demineralized water pipeline I is provided with a valve and is in a closed state when the system operates normally, and condensed water and demineralized water are poured into the deaerator to be heated in a low pressure heater together, the temperature difference of complementing water in the deaerator is decreased, vibration of the deaerator and great water spray of the oxygen outlet gate are effectively avoided, stability of the deaerator is improved, service life of the equipment is prolonged, and the operation cost is reduced.
Description
Technical field
The utility model belongs to a kind of boiler plant technical field, is specifically related to a kind of oxygen-eliminating device water charging system.
Background technology
Existing water charging system, as shown in Figure 1, comprise that the drain tank 1 that reclaims condensate water, drainage pump 2, condenser 3, the pump 4 that condenses, low-pressure heater 5 and oxygen-eliminating device 6 are communicated with successively by pipeline, described drain tank 1 is communicated with recycle-water pipeline 8, and described oxygen-eliminating device 6 is communicated with demineralized water pipeline I 7.From the condensate water of low-pressure heater after inlet regulating valve is regulated, enter oxygen-eliminating device, with mix in oxygen-eliminating device from the demineralized water between water treatment vehicle, through revolving the ejection of film antipriming pipe, form skirt shape moisture film, carry out hybrid heat transfer and mass transfer with heating steam from bottom to top, feedwater reaches rapidly the saturation temperature under the operating pressure.The Main Function of oxygen-eliminating device is to remove the noncondensable gas such as oxygen in the boiler feedwater and carbon dioxide, to guarantee the quality of feedwater.
During normal operation, condensate water is recycled to drain tank by the recycle-water pipeline, cover condenser by drainage pump, boost through the pump that condenses and to be heated to uniform temperature through low-pressure heater, cover oxygen-eliminating device, and directly enter oxygen-eliminating device from the demineralized water between water treatment vehicle by the demineralized water pipeline, when moisturizing and adjusting range are larger, because the excessive temperature differentials of condensate water and demineralized water, cause oxygen-eliminating device high vibration and oxygen discharging door to be sprayed water in a large number, affect the stability of oxygen-eliminating device operation, improved equipment operating cost.
Summary of the invention
The purpose of this utility model provides a kind of oxygen-eliminating device water charging system, causes the problem of oxygen-eliminating device high vibration and a large amount of water sprays of oxygen discharging door owing to condensate water and demineralized water excessive temperature differentials to solve prior art.
The technical scheme that the utility model adopts is: a kind of oxygen-eliminating device water charging system, comprise recycle-water pipeline, drain tank, oxygen-eliminating device and demineralized water pipeline, described recycle-water pipeline is communicated with described drain tank, described demineralized water pipeline comprises demineralized water pipeline I and demineralized water pipeline II, described demineralized water pipeline II is communicated with described drain tank, and described demineralized water pipeline I is communicated with described oxygen-eliminating device; Described demineralized water pipeline I is provided with valve.
The beneficial effects of the utility model are: the utility model is by being communicated with demineralized water pipeline II with drain tank, when being provided with valve and normally moving in system, demineralized water pipeline I is in closed condition, heating covers oxygen-eliminating device through low-pressure heater jointly to make condensate water and demineralized water, so that the oxygen-eliminating device moisturizing temperature difference reduces, the vibration of oxygen-eliminating device and a large amount of water sprays of oxygen discharging door have effectively been prevented, improve the stability of oxygen-eliminating device, extension device service life, reduced operating cost.

As shown in Figure 2, a kind of oxygen-eliminating device water charging system comprises drain tank 1, drainage pump 2, condenser 3, the pump 4 that condenses, low-pressure heater 5 and oxygen-eliminating device 6 and is communicated with successively by pipeline; Also comprise recycle-water pipeline 8 and demineralized water pipeline, recycle-water pipeline 8 is communicated with drain tank 1, the demineralized water pipeline comprises demineralized water pipeline I 7 and demineralized water pipeline II 10, demineralized water pipeline II 10 is communicated with drain tank 1, demineralized water pipeline I 7 is communicated with oxygen-eliminating device 6, demineralized water pipeline I 7 is provided with valve 9, and valve 9 is in closed condition when normally moving in system; Low-pressure heater 5 is comprised of the low-pressure heater of three same model.
Demineralized water pipeline I is in stand-by state, in order in case of emergency open valve 9 demineralized water is directly covered oxygen-eliminating device 6.
When system normally moves, valve-off 9, demineralized water covers drain tank 1 through demineralized water pipeline II 10 to be mixed with the condensate water that covers drain tank 1 through recycle-water pipeline 8, cover condenser 3 through drainage pump 2, boosting through the pump 4 that condenses is heated to about 125 ℃ through low-pressure heater 5 again, covers oxygen-eliminating device 6.
The utility model is communicated with demineralized water pipeline II 10 with drain tank 1, when being provided with valve 9 and normally moving in system, demineralized water pipeline I 7 is in closed condition, condensate water is mixed at drain tank 1 with demineralized water, cover condenser 3 through drainage pump 2, boosting through the pump 4 that condenses, 5 heating cover oxygen-eliminating device 6 through low-pressure heater again, so that the oxygen-eliminating device 6 moisturizing temperature difference reduce, the vibration of oxygen-eliminating device and a large amount of water sprays of oxygen discharging door have effectively been prevented, improved the stability of oxygen-eliminating device, extension device service life, reduce operating cost.
