Description
Technical field
The utility model relates to a kind of boiler and heating system equipment, is specifically related to a kind of spray-filling type deaerator.
Background technology
Oxygen-eliminating device is one of boiler and heating system key equipment, as poor in oxygen-eliminating device oxygen scavenging ability, by the heavy losses caused the corrosion of boiler feedwater pipeline, economizer and other auxiliary device.
Spray-filling type deaerator is by heating power method except the dissolved oxygen in anhydrating and other incondensable gas, thus improves quality and the temperature of feedwater, reduces the oxygen corrosion of unit equipment, improves the thermal efficiency of unit.Traditional spray-filling type deaerator very easily causes the de-stabilising effect of the oxygen-eliminating device temperature and pressure effect of deoxygenation when steam load fluctuates, cause waste and the boiler safety hidden danger of the energy simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of spray-filling type deaerator, and the instability of the oxygen-eliminating device temperature and pressure caused when can eliminate steam load fluctuation, deaerating effect is good.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise the upper shell, middle shell and the lower house that connect successively from top to bottom, upper shell upper end is provided with blast pipe, is provided with enterprising tracheae in upper shell, and enterprising tracheae is provided with water fender; Upper shell connects upper pipe, upper pipe connection safety valve; Center pipeline section is provided with in middle shell, center pipeline section connects two annular water distribution pipes, a water inlet pipe and a hydrophobic inlet tube of high-pressure heater, annular water distribution pipe is provided with multiple nozzle, middle shell lower surface is provided with pressure sensor, temperature sensor and multiple water spraying tray, pressure sensor and temperature sensor connection control device, controller connects high-pressure heater, water inlet water pump and steam production part; Be provided with Ω shape filler in lower house, Ω shape filler lower end is provided with filter screen, steam inlet and steam inlet pipe, and steam inlet pipe connects steam inlet.
Preferably, be provided with filler support in lower house, Ω shape filler is placed on filler support.
The beneficial effect that this oxygen-eliminating device produces is: be provided with pressure sensor and temperature sensor in middle shell, connection control device, when pressure sensor and temperature sensor detect abnormal data, controller controls high-pressure heater, water inlet water pump and steam production part coordinate operation, eliminate the steam load fluctuation in oxygen-eliminating device, thus eliminate the instability of oxygen-eliminating device temperature and pressure, deaerating effect is stablized.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of an embodiment of a kind of spray-filling type deaerator of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, Figure 1 shows that the schematic diagram of an embodiment of a kind of spray-filling type deaerator of the present utility model.In the present embodiment, spray-filling type deaerator comprises the upper shell 1, middle shell 2 and the lower house 3 that connect successively from top to bottom, upper shell 1 upper end is provided with blast pipe 21, enterprising tracheae 7 is provided with in upper shell, air inlet pipe 7 is fixed on the inwall of upper shell 1 by ellipsoidal head 4, enterprising tracheae 7 is provided with water fender 17, and water fender 17 is fixed on ellipsoidal head 4; Upper shell 1 connects upper pipe 5, upper pipe 5 connection safety valve; Be provided with center pipeline section 19 in middle shell 2, center pipeline section 19 connects two annular water distribution pipes, 6, water inlet pipe 18 and a hydrophobic inlet tube 9 of high-pressure heater, and annular water distribution pipe is provided with multiple nozzle 10 or nozzle 11, and main condensate enters from water inlet pipe 18; Middle shell 2 lower surface is provided with pressure sensor, temperature sensor and multiple water spraying tray 13, pressure sensor and temperature sensor connection control device, and controller connects high-pressure heater, water inlet water pump and steam production part; Be provided with Ω shape filler 20, Ω shape filler 20 lower end in lower house 3 and be provided with filter screen 16, steam inlet 8 and steam inlet pipe 12, steam inlet pipe 12 connects steam inlet 8, and filter screen 16 is fixed on filter plate 14.
With reference to figure 1, in an embodiment of the present utility model, be provided with filler support 15, Ω shape filler 20 in lower house 1 and be placed on filler support 15.
The heating steam Hybrid Heating that this oxygen-eliminating device is entered by feedwater and the upper gas tube of nozzle atomisation, reaches the heating of water and preliminary deoxygenation object.Through the water of preliminary deoxygenation when flowing downward, be filledly divided into very thin moisture film, moisture film continues to heat with the steam introduced from filler bottom, and completes oxygen removal process again.Owing to be there is larger specific surface by the moisture film cut, be thus conducive to water by heating and the effusion of dissolved gas.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
