Add easy flowing, this cambered surface, which is set, causes liquid to be not easy to rest on dispersion plate, reduces the impurity gathered on dispersion plate.
More preferably：The lower section of the dispersion plate of bottom is provided with the hot plate again for keeping apart delivery port and dispersion plate,
Hot plate is located above delivery port again, then hot plate is provided with multiple flow orifices；Current are through flow orifice i.e. through hot plate again.
Using said structure, in the oxygen-eliminating device of part and moisture fall when leaving dispersion plate still have part oxygen not by except
Go, this partial moisture falls on hot plate, further increasing the heat exchange area of current again after leaving the dispersion plate of bottom.Flowing
This of hole is so that the moisture again on hot plate is not easy to gather, and reduces the possibility of overflow phenomena generation.
More preferably：Reheated steam mouth is provided with below reheating plate, reheated steam mouth is communicated with high temperature steam pipeline.
Using said structure, the reheated steam mouth of high temperature steam pipeline is communicated with below reheating plate so that hot plate again
Lower section is also connected with high-temperature steam, improves the temperature of liquid surrounding environment on reheating plate.So that the liquid evaporation on hot plate is fast again
Degree is faster.
More preferably：Two layers adjacent of flow orifice of hot plate is staggered hot plate at least provided with two layers and again again.
Using said structure, then hot plate is staggered provided with two layers and two layers of flow orifice, the first layer liquid on hot plate again
Body, which leaves, can drop to the second layer after first layer again on hot plate, extend current in the residence time on hot plate again so that moisture
Contact with vapours is more comprehensive.Enhance the deaerating effect of oxygen-eliminating device.
In summary, the utility model has the advantages that：Provided with multiple dispersion plates staggeredly in oxygen-eliminating device, disperse
Plate is obliquely installed and dispersion plate is provided with multiple through holes so that the moisture entered from deoxygenation case water inlet can fall in dispersion plate first
Above and along dispersion plate flow, or fallen on through the through hole of dispersion plate on next piece of dispersion plate.Extend the liquid into deoxygenation case
Residence time of the body in deoxygenation case.Current are dropped down onto and can spread out on dispersion plate on dispersion plate, so as to increase on dispersion plate
The heat exchange area of moisture.So that moisture and the heat exchange that surrounding environment occurs are more thorough on dispersion plate, deoxygenation case is enhanced
Deaerating effect.The moisture that the setting of hot plate to fall again has part and fallen again on hot plate, and the high temperature below reheating plate
Jet chimney is connected with high-temperature steam so that the upper liquid of hot plate is heated so that this partially liq by deoxygenation more again again
Add the deaerating effect for thoroughly, further enhancing deoxygenation case.
