Abstract
The utility model provides an exhausted steam recovery device of a pressure deaerator. The exhausted steam recovery device is characterized in that a deaeration head of an atmospheric deaerator is connected with an exhausted stream recovery pipe externally connected with the pressure deaerator; the joint for the connection of the exhausted stream recovery pipe and the deaeration head is located between a packing layer and a spraying nozzle of the deaeration head; and an adjusting valve is arranged on the exhausted stream recovery pipe. The exhausted stream of the pressure deaerator is fed to the atmospheric deaerator to serve as the heating stream of the atmospheric deaerator. The exhausted steam recovery device not only can recover the exhausted stream of the pressure deaerator completely, but also has the advantages of simple transformation, low transformation cost, good energy-saving and consumption reduction effect, and so on, while not influencing the dissolved oxygen index of boiler feed water.
Description
Technical field
The utility model relates to the exhaust steam of the pressure oxygen-eliminating device of the Industrial Boiler that adopts two-stage thermal de-aeration technology or station boiler feedwater deaeration process and recycles.
Background technology
High pressure Industrial Boiler or station boiler employing two-stage thermal de-aeration technology remove the dissolved oxygen in the boiler feedwater, its first order oxygen-eliminating device is that atmosphere oxygen-eliminating device and second level oxygen-eliminating device are that the pressure oxygen-eliminating device all produces a certain amount of exhaust steam, because of the exhaust steam main component is moist steam and contains the ability that there is stronger oxide etch metal in aerobic, so traditionally exhaust steam is entered atmosphere.The entrained heat content of exhaust steam that bibliographical information thermal de-aeration technical process effluxes account for boiler supply water deaerating technology heating steam input heat content 5～15%, have considerable heat loss.
At present the oxygen-eliminating device exhaust steam is recycled as the existing mature technology of boiler feedwater, promptly uses demineralized water (or demineralized water) that exhaust steam is carried out carrying out carbonated drink separation again after the blended absorbent, water by pump return oxygen-eliminating device again after the deoxygenation as boiler feedwater.Two-stage thermal de-aeration technology is adopted in the feedwater of present domestic most high-pressure boilers, the general emptying of the exhaust steam of its pressure oxygen-eliminating device or adopted one the cover composite set reclaim exhaust steam, at least increase a consumer, not only consumed electric energy but also increased the unstability of system's operation.To adopting the boiler supply water deaerating technology of two-stage thermal de-aeration technology, if the existing oxygen-eliminating device exhaust steam recovery and utilization technology of employing will increase many cover steam exhaust recovering devices, the stability of system's operation more be cannot say for sure to demonstrate,prove.
The utility model content
Be applied to increase power consumption and the instable problem of increase that two-stage thermal de-aeration technology exists in order to solve existing thermal deaerator exhaust steam recovery and utilization technology, the utility model provides a kind of exhaust steam recovery and utilization technology and device at the pressure oxygen-eliminating device, rebuilding construction is simple, also need not consumed power.
Technical solution adopted in the utility model is:
(1) exhaust steam of pressure oxygen-eliminating device enters the heating steam of the deoxygenation head of atmosphere oxygen-eliminating device as the atmosphere oxygen-eliminating device by the exhaust steam recovery tube.
(2) the exhaust steam recovery tube of pressure oxygen-eliminating device enters the access point of atmosphere oxygen-eliminating device deoxygenation head between the packing layer and spray head of deoxygenation head.
Architectural feature is: the external exhaust steam recovery tube 2 of pressure oxygen-eliminating device 1 connects the deoxygenation 4 of atmosphere oxygen-eliminating devices 3, and the access point A that exhaust steam recovery tube 2 connects deoxygenations 4 is between the packing layer 5 and spray head 6 of deoxygenation 4.
Control valve 7 is set on the exhaust steam recovery tube 2.
Good effect of the present utility model: the moisture content of whole pressure recovery oxygen-eliminating device exhaust steam and the heat content of exhaust steam moisture content.The utility model be applicable to boiler feedwater adopt two-stage thermal de-aeration technology the exhaust steam of pressure oxygen-eliminating device recycle.The utility model is compared with existing oxygen-eliminating device exhaust steam recovery and utilization technology, has tangible technical advantage, neither increase power consumption, can all recycle the exhaust steam of pressure oxygen-eliminating device again, the energy conservation and consumption reduction effects benefit is obvious, and enforcement is simple, improvement expenses is low, does not influence the dissolved oxygen index of boiler feedwater simultaneously.So market application foreground of the present utility model is very wide.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Among the figure: 1. pressure oxygen-eliminating device, 2. exhaust steam recovery tube, 3. atmosphere oxygen-eliminating device, 4. deoxygenation head, 5. packing layer, 6. spray head, 7. control valve, 8. exhaust steam exhaust-valve.
The specific embodiment
The external exhaust steam recovery tube 2 of pressure oxygen-eliminating device 1 connects the deoxygenation 4 of atmosphere oxygen-eliminating devices 3, and the access point A that exhaust steam recovery tube 2 connects deoxygenations 4 is between the packing layer 5 and spray head 6 of deoxygenation 4.
Control valve 7 is set on the exhaust steam recovery tube 2, can be electronic or manual control valve 7.
Concrete measure (1): as shown in drawings, the access point A point that the deoxygenation 4 that the exhaust steam of pressure oxygen-eliminating device 1 enters atmosphere oxygen-eliminating device 3 by exhaust steam recovery tube 2, exhaust steam enter deoxygenation 4 is between the packing layer 5 and spray head 6 of deoxygenation 4.For the exhaust steam amount of controlled pressure oxygen-eliminating device, an exhaust steam control valve 7 can be set on the exhaust steam recovery tube 2.
Measure (2): as shown in drawings, pressure oxygen-eliminating device exhaust steam exhaust-valve 8 keeps standby, and the exhaust steam of pressure oxygen-eliminating device picks out between an exhaust-valve 8 and a deoxygenation exhaust steam export, and inserts the deoxygenation 4 of atmosphere oxygen-eliminating device again.
Claims (3)
1. pressure oxygen-eliminating device exhaust steam recycle device, comprise pressure oxygen-eliminating device (1), exhaust steam exhaust-valve (8), it is characterized in that: the external exhaust steam recovery tube (2) of pressure oxygen-eliminating device (1) connects the deoxygenation head (4) of atmosphere oxygen-eliminating device (3), and the access point A that exhaust steam recovery tube (2) connects deoxygenation head (4) is positioned between the packing layer (5) and spray head (6) of deoxygenation head (4).
