Fig. 1 is systematic schematic diagram of the present invention.
Detailed description of the invention
First inlet channel 24, second reflux line 23 in Fig. 1, the 3rd drainage pipe 25, the 5th upward arrow direction, hot-water outlet pipe road 27 represent the water (flow) direction in the present invention; In Fig. 1, the 4th direction of arrow entered on steam pipeline 26 represents and enters steam direction in the present invention.
As shown in Figure 1, the deoxygenation water tank that prevents of the present invention overflows the device of water, comprise softening water tank 1 and deoxygenation water tank 13, softening water tank 1 is communicated with by the first inlet channel 24 with deoxygenation water tank 13, on described first inlet channel 24, the first ball valve 2 is set gradually by water (flow) direction, first water pump 3, first flap valve 4, second ball valve 5, pressure sensor 6, 3rd ball valve 8 and the first motor operated valve 9, described pressure sensor 6 and the first water pump 3 control connection, described deoxygenation water tank 13 being provided with liquid level sensor 10(liquid level sensor 10 can adopt the content gauge of band liquid level sensor to substitute), described liquid level sensor 10 and the first water pump 3 and the first motor operated valve 9 control connection respectively, described deoxygenation water tank 13 is also provided with band water seal bleed off pipe 7, described band water seal bleed off pipe 7 is communicated with described softening water tank 1 by the second reflux line 23, on described second reflux line 23, the 4th ball valve 21 and the second flap valve 22 is disposed with by water (flow) direction, the end of described band water seal bleed off pipe 7 is provided with the 5th ball valve 21.
The bottom connection of described deoxygenation water tank is provided with the 3rd drainage pipe 25, is disposed with the 6th ball valve 18 and the second motor operated valve 19 by water (flow) direction on described 3rd drainage pipe 25.Described deoxygenation water tank 13 is communicated with and is provided with the 4th and enters steam pipeline 26, press in steam direction and enter on steam pipeline 16 to be disposed with the 3rd motor operated valve 11 and the 3rd flap valve 12 the described 4th.Described deoxygenation water tank 13 is communicated with and is provided with the 5th hot-water outlet pipe road 27, on described 5th hot-water outlet pipe road 27, be disposed with the 7th ball valve 14, second water pump 15, the 4th flap valve 16, the 8th ball valve 17 by water (flow) direction.
When the present invention works, the demineralized water of softening water tank 1 enters deoxygenation water tank 13 through the first ball valve 2, first water pump 3, first flap valve 4, second ball valve 5, pressure sensor 6, the 3rd ball valve 8 and the first motor operated valve 9 successively along the first inlet channel 24.First water pump 3 is constant pressure water supply, when liquid level sensor 10 detects that the water level of deoxygenation water tank 13 is in low water stage, first motor operated valve 9 is opened, demineralized water enters deoxygenation water tank 13, first inlet channel 24 pressure starts to decline, when pressure sensor 6 detects the first inlet channel 24 pressure lower than 0.25MPa, and the first water pump 3 startup optimization, constantly the demineralized water of softening water tank 1 is supplied to deoxygenation water tank 13, the liquid level of deoxygenation water tank 13 starts to rise; When the water level of deoxygenation water tank 13 reaches high water level, when liquid level sensor 10 detects that the water level of deoxygenation water tank 13 reaches high water level, first motor operated valve 9 cuts out, first inlet channel 24 pressure increase, when pressure sensor 6 detects that the first inlet channel 24 pressure reaches 0.3MPa simultaneously, first water pump 3 is out of service, stops to deoxygenation water tank 13 for demineralized water, and the water level of deoxygenation water tank 13 stops rising.
Because motor operated valve often occurs stuck phenomenon, be stuck in spool place when the impurity particularly in ducted welding slag or water flows to electronic spool with water, be not closed completely when motor operated valve cuts out close, in motor operated valve occurs, leak phenomenon.When the first motor operated valve 9 closes not tight or interior leakage, the first inlet channel 24 pressure supplying demineralized water to deoxygenation water tank 13 can not rise, pressure sensor 6 can't detect the signal that namely high-voltage signal can't detect 0.3MPa all the time, even if when the first water pump 3 constantly can run the water level arrival high water level of the deoxygenation water tank 13 that goes down.At this moment because the first motor operated valve 9 is not closed completely or interior leakage, first water pump 3 is not out of service, the water level of deoxygenation water tank 13 can continue to rise, when the water level of deoxygenation water tank 13 reaches surcharge water level, and water level also do not reach the water inlet of band water seal bleed off pipe 7 and deoxygenation water tank 13 also unrestrained water time, the liquid level sensor 10 of deoxygenation water tank 13 detects that surcharge water level Signal transmissions is to the first water pump 3, first water pump 3 is out of service, even if at this moment pressure sensor 6 detects that the first inlet channel 24 pressure is lower than 0.25MPa, first water pump 3 is still out of service, deoxygenation water tank 13 is avoided to overflow water.
Usual ball valve 20 is closed; ball valve 21 is often opened; even if the first motor operated valve 9 or liquid level sensor 10 fault; or the fault such as pressure sensor 6 causes protection system malfunctioning; deoxygenation water tank 13 water level reaches deoxygenation water tank 13 and overflows water water level, and after the water band water seal bleed off pipe 7 diffused out diffuses out, the water diffused out refluxes into softening water tank 1 through the 4th ball valve 21, second flap valve 22 along the second reflux line 23 successively; the water diffused out directly is not drained, saving water resource.Only under special circumstances, just the 5th ball valve 20 is opened, the 4th ball valve 21 is closed, unrestrained water is discharged directly into trench.
The blowdown of deoxygenation water tank 13 is drained through the 6th ball valve 18, second motor operated valve 19 successively along the 3rd drainage pipe 25 of water tank bottom, and the second motor operated valve 19 can setting-up time, regularly opens the impurity of discharge deoxygenation water tank 13 bottom precipitation.
Steam enters steam pipeline 26 along the 4th and enters deoxygenation water tank 13 through the 3rd motor operated valve 11, the 3rd flap valve 12 successively and heat demineralized water in deoxygenation water tank 13, is delivered to boiler and utilizes successively after the demineralized water in deoxygenation water tank 13 is heated by steam deoxygenation along the 5th hot-water outlet pipe road 27 through the 7th ball valve 14, second water pump 15, the 4th flap valve 17, the 8th ball valve 16.
The present invention is by the control mode of change first water pump 3; the first water pump 3 is made not only to want constant pressure water supply; the control of liquid level sensor 10 on deoxygenation water tank 13 is subject to again especially when deoxygenation water tank 13 surcharge water level; the first motor operated valve 9 two ore control protection of being intake by the first water pump 3 and deoxygenation water tank 13 prevents deoxygenation water tank 13 from overflowing water; even if the deoxygenation water tank 13 that the simultaneous faultss such as liquid level sensor 10, first motor operated valve 9 cause overflows water; also the Water Sproading diffused out can be entered softening water tank 1, avoid the in line ditch of demineralized water diffused out to form waste.
Above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: still can modify to the present invention or equivalent replacement, and not departing from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of right of the present invention.
