Compared with a film deaerator, by adopting the headless spray deaerating device, deoxidation and water storage are finished in the same shell; an external deaerating head does not need to be combined with a water tank; the headless spray deaerating device is simple and compact in structure, convenient to install and maintain; the water is subjected to two-stage deoxidation and secondary deoxidation; the jet holes are arranged below the water level; the steam jet from the jet holes directly contacts with the water; and the headless spray deaerating device is high in deoxidation efficiency and more thorough to deoxidize.
Description
Technical field
The utility model belongs to feedwater thermal de-aeration technical field, is specifically related to a kind of spraying type de-aerator plant without a head, is used for removing the free oxygen of therrmodynamic system supplementary feed, is applied to fields such as fuel-burning power plant, oil, chemical industry.
Background technology
In the therrmodynamic system of fuel-burning power plant or oil, chemical field, free oxygen causes corrosion to the heat power equipment metal, shortens the work-ing life of equipment greatly, reduces the reliability of equipment, even can cause the generation of security incident.The gas that is dissolved in the boiler feed water system is generally brought into by supplementary feed, and therefore, the dissolved oxygen of removing in the supplementary feed is the important means of guaranteeing the heat power equipment safe operation.
Use at present more widely that de-aerator plant is film deoxidizer, but film deoxidizer is made up of external placed type deoxygenation head and water tank, cisten mechanism is complicated, volume is big, operating performance is poor, needs bigger installing space, make and installation cost higher; Core deoxygenation parts are fixed, non-dismountable in the deoxygenation head, and maintenance is difficult, operation stability is poor.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field de-aerator plant exists, the purpose of this utility model is, a kind of spraying type de-aerator plant without a head is provided, and deaerating effect is good, and is stable, and long service life is easy to dismounting, convenient maintenance.
The spraying type de-aerator plant without a head that the utility model provides, comprise that housing, inlet water mix pipe, mixing water conduit, steam inlet pipe, steam duct and some intumescence pipes, described inlet water mixes pipe and the steam inlet pipe is installed in housing top respectively, described mixing water conduit laterally is connected inlet water and mixes the pipe lower end, and described steam duct laterally is connected steam inlet pipe lower end.Described some intumescence pipes vertically are distributed on horizontal steam duct downside, offer several spray orifices on the intumescence pipe, and spray orifice is positioned at below the water surface of housing bottom water.It also comprises several atomizing nozzles, and several atomizing nozzles are distributed on mixing water conduit downside, steam duct top.It also comprises oxygen discharging tube, and oxygen discharging tube is installed in housing top.It also comprises rising pipe, and rising pipe is installed in the housing downside.
The spraying type de-aerator plant without a head that the utility model provides, its beneficial effect are, have cancelled external deoxygenation head, and deoxygenation head and the water tank of original technology is combined in the same shell of tank, and be simple in structure, compact, is convenient to install, safeguard, stable; Be provided with the two-stage de-aerator plant, oxygen removal efficiency height, effective; Inlet water adopts and mixes form of tubes, and the water of different pressures is after mixing, and the water that forms the pressure unanimity enters the range of atomization through nozzle, has effectively avoided bias current; Offer several spray orifices on the intumescence pipe, steam is mapped to the saturation water from spray orifice, this sprays and is turbulent flow, liquid not only moves along the axially bored line direction, but also violent transverse movement takes place, so the heat transmission has not only been accelerated in constantly blending mutually of fluid, improve oxygen removal efficiency, and reached better deaerating effect.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of an embodiment of the utility model;
Fig. 2 is the part sectioned view of intumescence pipe.
Mark among the figure:
1. spray orifice; 2. housing; 3. steam inlet pipe; 4. oxygen discharging tube; 5. inlet water mixes pipe; 6. atomizing nozzle; 7. rising pipe; 8. steam duct; 9. intumescence pipe; 10. mixing water conduit.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the spraying type de-aerator plant without a head that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the spraying type de-aerator plant without a head of present embodiment, comprise that housing 2, inlet water mix pipe 5, mixing water conduit 10, steam inlet pipe 3, steam duct 8 and some intumescence pipes 9, described inlet water mixes pipe 5 and steam inlet pipe 3 is installed in housing 2 tops respectively, described mixing water conduit 10 laterally is connected inlet water and mixes pipe 5 lower ends, and described steam duct 8 laterally is connected steam inlet pipe 3 lower ends.Described some intumescence pipes 9 vertically are distributed on horizontal steam duct 8 downsides, offer several spray orifices 1 on the intumescence pipe 9, and spray orifice 1 is positioned at below the water surface of housing 2 bottom water.It also comprises several atomizing nozzles 6, and several atomizing nozzles 6 are distributed on mixing water conduit 10 downsides, steam duct 8 tops.It also comprises oxygen discharging tube 4, and oxygen discharging tube 4 is installed in housing 2 tops.It also comprises rising pipe 7, and rising pipe 7 is installed in housing 2 downsides.
The principle of work of spraying type de-aerator plant without a head is as follows: each Lu Shuijing inlet water of various different pressures, differing temps mixes and enters the mixing water conduit after pipe mixes, the many small water droplets that are atomized of atomizing nozzle ejection through mixing water conduit downside, and with housing in steam on the water surface carry out heat exchange, gases such as incoagulable oxygen are discharged from the oxygen outlet on housing top, finish the one-level oxygen removal process.Fall into the water of housing bottom through the water of one-level deoxygenation, because steam enters steam duct by the steam inlet pipe, enters the intumescence pipe then, the spray orifice from the intumescence pipe sprays, spray orifice is positioned at the underwater of housing bottom water, therefore, deoxygenation falls into the water of housing bottom through one-level, directly contacts with steam, carry out heat exchange, incoagulable oxygen is discharged from the oxygen outlet on housing top, finishes the secondary deoxygenation, derives from the rising pipe of housing downside through the water of secondary deoxygenation.
Spraying type de-aerator plant without a head is compared with film deoxidizer, and deoxygenation and water storage are finished in same housing, does not need external placed type deoxygenation head and water tank to be used in combination, and is simple and compact for structure, is convenient to install, safeguard; Water is through the two-stage deoxygenation, and the secondary deoxygenation, and spray orifice is arranged on below the water surface, and the steam that sprays from spray orifice directly contacts with water, the oxygen removal efficiency height, and deoxygenation is more thorough.
Above-mentioned explanation only be for clearly demonstrate that the utility model does for example, be not to be restriction to the utility model embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Everyly belong to the row that apparent variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
