Description
technical field:
the utility model relates to a kind of waterworks of oxygen-eliminating device.
background technology:
one of necessary equipment of oxygen-eliminating device Shi Shi power plant, it can remove oxygen unnecessary in boiler feedwater, and ensure system high efficiency even running, its security seems particularly important.Along with the proposition of high-efficiency environment friendly energy-conservation target, nuclear power market expanding day, the structure of the deaerator feedwater device in the past in thermoelectricity, can not meet the harsher condition of work of nuclear power and strict safety requirements completely, wherein most distinct issues are exactly, nuclear power deaerator is larger than the temperature difference of thermoelectricity oxygen-eliminating device in running, this just makes nuclear power deaerator need to bear larger thermal (temperature difference) stress, if and the form of thermoelectricity deaerator feedwater device still continued to use by nuclear power deaerator waterworks, will occur because waterworks rigidity is large, compatibility of deformation ability is weak, supporting construction is caused to be pulled off or the failure modes such as crackle appear in feed main.
summary of the invention:
the purpose of this utility model is to provide a kind of waterworks of oxygen-eliminating device, effectively can alleviate thermal (temperature difference) stress, makes oxygen-eliminating device trouble free service.
above-mentioned object is realized by following technical scheme:
a kind of waterworks of oxygen-eliminating device, its composition comprises: stay pipe, described stay pipe is welded on feed main, described feed main is welded on distributing pipe, described distributing pipe is welded on except in oxygen jet adapter, described deaerator nozzle adapter is welded on cylindrical shell, and described cylindrical shell is connected with support.
the waterworks of described oxygen-eliminating device, described stay pipe end has groove.
the waterworks of described oxygen-eliminating device, described distributing pipe is formed by steel pipe and elbow welding, and described steel tube end part has groove.
beneficial effect:
1. first the utility model cooling water enters in feed main by the adapter on feed main, then by feed main, cooling water is distributed to each distributing pipe, water in distributing pipe flow into nozzle adapter again, finally spray in cylindrical shell, mix with the high-temperature steam in cylindrical shell, reach the object of deoxygenation.
cooling water in the utility model waterworks and the high-temperature steam in cylindrical shell can produce larger thermal (temperature difference) stress, and the utility model can effectively alleviate this thermal (temperature difference) stress, makes oxygen-eliminating device trouble free service.
the utility model can meet the special circumstances that there is the larger temperature difference between nuclear power deaerator cylindrical shell and feed main, by the flexibility of gaining water-supplying device, makes the stress distribution of structure more reasonable, thus has ensured the security of deaerator feedwater device.
it is large that the utility model efficiently solves waterworks rigidity, and compatibility of deformation ability is weak, and supporting construction is pulled off or the failure modes such as crackle appear in feed main.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model;
accompanying drawing 2 is top views of accompanying drawing 1;
accompanying drawing 3 is left views of accompanying drawing 1.
