Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of the present invention.
Detailed description of the invention
In Fig. 1, first inlet channel the 24, second reflux line the 23, the 3rd drainage pipeline the 25, the 5th upward arrow direction, hot-water outlet pipe road 27 represents the water (flow) direction in the present invention；In Fig. 1, the 4th enters the direction of arrow on jet chimney 26 and represents and enter steam direction in the present invention.
nullAs shown in Figure 1，The deoxygenation water tank that prevents of the present invention overflows the device of water，Including softening water tank 1 and deoxygenation water tank 13，Softening water tank 1 is connected 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 check-valves 4、Second ball valve 5、Pressure transducer 6、3rd ball valve 8 and the first electrodynamic valve 9，Described pressure transducer 6 controls to be connected with the first water pump 3，Being provided with liquid level sensor 10(liquid level sensor 10 on described deoxygenation water tank 13 can use the liquidometer of band liquid level sensor to substitute)，Described liquid level sensor 10 controls to be connected with the first water pump 3 and the first electrodynamic valve 9 respectively，Band water seal overflow pipe 7 it is additionally provided with on described deoxygenation water tank 13，Described band water seal overflow pipe 7 is connected 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 check-valves 22 it is disposed with by water (flow) direction，The end of described band water seal overflow pipe 7 is provided with the 5th ball valve 21.
The bottom of described deoxygenation water tank is provided with and communicated with the 3rd drainage pipeline 25, is disposed with the 6th ball valve 18 and the second electrodynamic valve 19 by water (flow) direction on described 3rd drainage pipeline 25.It is provided with and communicated with the 4th on described deoxygenation water tank 13 and enters jet chimney 26, press in steam direction and enter on jet chimney 16, to be disposed with the 3rd electrodynamic valve 11 and the 3rd check-valves 12 the described 4th.It is provided with and communicated with the 5th hot-water outlet pipe road 27 on described deoxygenation water tank 13, on described 5th hot-water outlet pipe road 27, is disposed with the 7th ball valve the 14, second water pump the 15, the 4th check-valves the 16, the 8th ball valve 17 by water (flow) direction.
When the present invention works, the softening water of softening water tank 1 enters deoxygenation water tank 13 through first ball valve the 2, first water pump the 3, first check-valves the 4, second ball valve 5, pressure transducer the 6, the 3rd ball valve 8 and the first electrodynamic valve 9 successively along the first inlet channel 24.First water pump 3 is constant pressure water supply, when the water level that liquid level sensor 10 detects deoxygenation water tank 13 is in low water level, first electrodynamic valve 9 is opened, soften water and enter deoxygenation water tank 13, first inlet channel 24 pressure begins to decline, when pressure transducer 6 detects the first inlet channel 24 pressure less than 0.25MPa, and the first water pump 3 startup optimization, constantly it is supplied to deoxygenation water tank 13, the liquid level of deoxygenation water tank 13 to begin to ramp up in the softening water of softening water tank 1；When the water level of deoxygenation water tank 13 reaches high water level, liquid level sensor 10 detects when the water level of deoxygenation water tank 13 reaches high water level, first electrodynamic valve 9 cuts out, first inlet channel 24 pressure rises, pressure transducer 6 detects when 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 softening water, and the water level of deoxygenation water tank 13 stops rising.
Often occurring that due to electrodynamic valve the welding slag in stuck phenomenon, particularly pipeline or the impurity in water are stuck at spool when flowing to electronic spool with water, be not closed completely when electrodynamic valve cuts out close, there is internal hemorrhage due to trauma phenomenon in electrodynamic valve.When the first electrodynamic valve 9 closes not tight or internal hemorrhage due to trauma, the first inlet channel 24 pressure softening water to deoxygenation water tank 13 supply will not rise, pressure transducer 6 can't detect high-voltage signal all the time and i.e. can't detect the signal of 0.3MPa, even if the first water pump 3 can constantly run the water level arrival high water level of the deoxygenation water tank 13 that goes down.At this moment it is not closed completely or internal hemorrhage due to trauma due to the first electrodynamic valve 9, first water pump 3 is the most out of service, the water level of deoxygenation water tank 13 may proceed to rise, when the water level of deoxygenation water tank 13 reaches surcharge water level, and water level be also not reaching to the water inlet i.e. deoxygenation water tank 13 of band water seal overflow pipe 7 the most do not overflow water time, the liquid level sensor 10 of deoxygenation water tank 13 detects that surcharge water level signal is transferred to the first water pump 3, first water pump 3 is out of service, even if at this moment pressure transducer 6 detects that the first inlet channel 24 pressure is less than 0.25MPa, first water pump 3 is the most out of service, deoxygenation water tank 13 is avoided to overflow water.
Generally ball valve 20 is closed; ball valve 21 is normally opened; even if the first electrodynamic valve 9 or liquid level sensor 10 fault; or the fault such as pressure transducer 6 causes protecting system down; deoxygenation water tank 13 water level reaches deoxygenation water tank 13 and overflows water water level, and after the water band water seal overflow pipe 7 diffused out diffuses out, the water diffused out flows back into softening water tank 1 through the 4th ball valve the 21, second check-valves 22 successively along the second reflux line 23; the water diffused out the most directly is drained, saving water resource.The most 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 the 18, second electrodynamic valve 19 successively along the 3rd drainage pipeline 25 of water tank bottom, and the second electrodynamic valve 19 can set the time, periodically opens the impurity of discharge deoxygenation water tank 13 bottom precipitation.
Steam enters jet chimney 26 along the 4th and enters, through the 3rd electrodynamic valve the 11, the 3rd check-valves 12, the softening water that deoxygenation water tank 13 heats in deoxygenation water tank 13 successively, and the softening water in deoxygenation water tank 13 is heated by steam deoxygenation tailing edge the 5th hot-water outlet pipe road 27 and is delivered to boiler utilization through the 7th ball valve the 14, second water pump the 15, the 4th check-valves the 17, the 8th ball valve 16 successively.
The present invention is by changing the control mode of the first water pump 3; the first water pump 3 is made not only to want constant pressure water supply; especially when deoxygenation water tank 13 surcharge water level again by the control of liquid level sensor 10 on deoxygenation water tank 13; the first electrodynamic valve 9 two ore control intake by the first water pump 3 and deoxygenation water tank 13 is protected from deoxygenation water tank 13 and overflows water; even if the deoxygenation water tank 13 that the simultaneous faults such as liquid level sensor the 10, first electrodynamic valve 9 cause overflows water; also the Water Sproading diffused out can be entered softening water tank 1, it is to avoid the in line ditch of softening water diffused out forms waste.
Above example is only in order to illustrative not limiting technical scheme, although the present invention being described in detail with reference to above-described embodiment, it will be understood by those within the art that: still the present invention can be modified or equivalent, any modification or partial replacement without departing from the spirit and scope of the present invention, it all should be contained in the middle of scope of the presently claimed invention.
