The utility model provides a water seal stabiliser installs on the exhaust steam discharge pipeline of heating power oxygen-eliminating device, and is concrete, installs on deoxidization water tank exhaust steam pipe 4 and deoxidization head exhaust steam pipe 5, and its theory of operation is:
1. when water seal stabiliser initial use, inject cold water into water tank 1 through moisturizing pipeline 3, make the water level height reach 0.8 meters, level mutually with water tank drain pipe 1A's height, promptly: a water tank drain pipe 1A is arranged at the height of 0.8 m of the water level, an overflow pipe 1B is arranged at the position of 1 m of the height, and the overflow port of the overflow pipe is the highest water level of the water seal pressure stabilizer.
2. Under normal working conditions, the second valve F2 and the third valve F3 are opened, the first valve F1, the fourth valve F4 and the fifth valve F5 are closed, at the moment, exhaust steam discharged by a thermal deaerator through a deaerating water tank steam exhaust pipeline 4 enters the water bottom of the water tank 1 through a 1 st steam exhaust pipe G1, meanwhile, exhaust steam discharged by the thermal deaerator through a deaerating head steam exhaust pipeline enters the water bottom of the water tank 1 through a 4 th steam exhaust pipe G4, the exhaust steam and water in the water tank are subjected to sufficient heat exchange to heat the water in the water tank, after the whole water seal voltage stabilizer operates for a period of time, the heated water in the water tank can flow to the original water tank through a water tank drain pipe 1A, so that hot water is conveyed to the original water tank, the heat of the exhaust steam is utilized, or the heated water in the water tank can be conveyed to a drain pump through a drain pipe 1D, and then the drain pump conveys the hot water to other occasions needing the hot water, the utilization of the heat of the dead steam is realized; meanwhile, when the heated water in the water tank is discharged to the outside, the water level in the water tank must be maintained at 0.8 m, and therefore, low-temperature water needs to be supplied to the water tank through the water supply pipe 3. The water level in the water tank is maintained at 0.8 m, and the constancy of the pressure in the thermal deaerator can be maintained, namely: the pressure in the thermal deaerator is maintained by utilizing the hydrostatic head, and the pressure in the thermal deaerator can be maintained at 20Kpa when the water level in the water tank is maintained at 0.8 m.
In addition, after the exhaust steam and the water in the water tank are subjected to sufficient heat exchange, the exhaust steam flows upwards from the water surface in the water tank and flows into the washing and absorbing tower 2, at the moment, the sixth valve F6 is opened, the low-temperature water conveyed by the water replenishing pipe reaches the bottom of the absorbing tower through the water conveying pipe 3B of the absorbing tower, flows downwards in the absorbing tower, is subjected to heat exchange with the rising exhaust steam again, and is finally discharged to the external atmosphere through the 3 rd steam discharging pipe G3.
3. Under an abnormal working condition, when the amount of the exhaust steam generated by the thermal deaerator is large, the amount of the exhaust steam exceeds the heat exchange capacity of water and the exhaust steam in the water tank, at the moment, in order to ensure the constant pressure in the thermal deaerator, a first valve F1, a second valve F2 and a third valve F3 are opened at the same time, a fourth valve F4 and a fifth valve F5 are closed, at the moment, the exhaust steam generated by the thermal deaerator enters the water bottom part in the water tank through a first steam exhaust pipe G1 and a 4 steam exhaust pipe G4 to exchange heat, and meanwhile, the resistance of the water level of 0.8 meter needs to be overcome to continuously rise until the exhaust steam flows out of the surface of water at normal pressure, the conveying resistance of the exhaust steam in the path is large, and the flow rate is slow; on the other hand, the exhaust steam that the thermal power oxygen-eliminating device produced still directly enters into the inside of washing absorption tower 2 through 2 nd exhaust pipe G2, because this way exhaust steam directly enters into the inside of washing absorption tower 2, consequently can not meet the resistance of water, the velocity of flow is very fast, can effectively adjust the pressure in the thermal power oxygen-eliminating device, avoids the condition of the superpressure appearing in the thermal power oxygen-eliminating device. The dead steam directly entering the washing absorption tower 2 contacts with washing liquid sprayed downwards in the washing absorption tower for heat exchange, and is finally discharged to the external environment through a 3 rd steam discharge pipe G3.
4. When the water seal voltage stabilizer breaks down or can not be normally used due to maintenance, in order to ensure the normal use of the thermal deaerator, at the moment, the first valve F1, the fourth valve F4 and the fifth valve F5 are opened, the second valve F2 and the third valve F3 are closed, and at the moment, exhaust steam generated by the thermal deaerator is directly discharged to the external environment without passing through the water seal voltage stabilizer.
Therefore, the utility model provides a water seal stabiliser has following advantage:
(1) under normal operating mode, the liquid level keeps invariable in the water seal stabiliser to the realization does not need to operate the exhaust steam discharge valve to the steady voltage function of heating power oxygen-eliminating device, has reduced personnel intensity of labour, has also effectively guaranteed the normal operating of heating power oxygen-eliminating device, improves the operation security of heating power oxygen-eliminating device.
(2) The waste steam discharged by the thermal deaerator is subjected to heat recovery and reutilization through the water seal voltage stabilizer, so that the energy waste is avoided, and the problem of environment pollution caused by direct exhaust of the waste steam is solved. Therefore, no exhaust steam is directly discharged, and the thermal pollution of the exhaust steam is eliminated.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be viewed as the protection scope of the present invention.
