Description

A kind of energy-saving thermal deaerator
Technical field
The utility model relates generally to oxygen-eliminating device field, particularly thermal deaerator.
Background technology
GB50041-2008 " Code for design of boiler house " advantage to thermal deaerator is summed up, but is not introduced its shortcoming.In fact, thermal deaerator limits due to its operation principle, causes following two defects:
1, Boiler Steam is consumed.
Because thermal deaerator adopts the steam of boiler that feed temperature is brought up to more than 105 degree, thus reach the effect of deoxygenation.Thus it consumes the some vapor of boiler, makes the actual quantity of steam that can use of user be less than the specified evaporation capacity of boiler.
For 10 tons/time, 1.25MPa boiler.The evaporation capacity of design is 10000kg/ hour.But its matching used thermal deaerator consumes quantity of steam at about 1500kg/h.This boiler can be less than the 10000kg/h of design for the quantity of steam of user, most multipotency reaches 85000kg/h.
2, because thermal deaerator supply water temperature is 105 DEG C, cause exhaust gas temperature generally can only be reduced to 150 ~ 160 DEG C, if continue to reduce exhaust gas temperature, because the temperature difference is too little, need to consume a large amount of steel, cost performance can reduce greatly.Therefore compare other low temperature oxygen-eliminating devices, thermal deaerator is unfavorable for that boiler reduces exhaust gas temperature.
Utility model content
The utility model will provide a kind of technical scheme, to solve the technical problem that existing thermal deaerator exists.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of energy-saving thermal deaerator, comprise thermal deaerator and heat exchanger, the deaerated water outlet of thermal deaerator connects the deaerated water import of heat exchanger, the demineralized water outlet of heat exchanger connects the demineralized water import of thermal deaerator, the demineralized water water inlet of heat exchanger connects soft water source, and the deaerated water outlet of heat exchanger is connected with boiler feed water mouth.
Described heat exchanger can adopt various ways, and its feature is that thermal deaerator deaerated water exports to the import of heat exchanger deaerated water and arrives between the outlet of heat exchanger deaerated water and boiler feed water mouth as closed conduit connects again.
Boiler feedwater of the present utility model from oxygen-eliminating device out after, directly enter boiler through pipeline, be in the closed state in pipeline from oxygen-eliminating device to boiler always, except the boiler feedwater (deaerated water) of peroxide can not contact air again, oxygen content also can not increase.That is, the reduction of oxygen-eliminating device leaving water temperature can not affect the deaerating effect of thermal deaerator.
Accompanying drawing explanation
Fig. 1 is existing thermal deaerator schematic diagram.
Fig. 2 is the utility model thermal deaerator schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 ~ 2 and detailed description of the invention, the utility model is described in further detail.
The utility model provides a kind of energy-saving thermal deaerator, comprise thermal deaerator 1 and heat exchanger 2, the deaerated water outlet 11 of thermal deaerator 1 connects the deaerated water import 21 of heat exchanger 2, the demineralized water outlet 24 of heat exchanger 2 connects the demineralized water import 12 of thermal deaerator 1, the demineralized water import 22 of heat exchanger 2 connects softened water tank, and the deaerated water outlet 23 of heat exchanger 2 is connected with boiler feed water mouth.Equally with common thermal deaerator on oxygen-eliminating device 1 be also provided with exhaust outlet 14 and steam inlet 13.
Sleeve structure is adopted: for closed conduit connects between heat exchanger deaerated water import 21 and heat exchanger deaerated water outlet 23 for heat exchanger, a part deaerated water import 21 and heat exchanger deaerated water in heat exchanger of the pipeline between the demineralized water water inlet 22 of heat exchanger 2 and the demineralized water delivery port 24 of heat exchanger 2 export in the closed conduit between 23, form the heat exchange of the large pipe box tubule of a part.Construct according to actual needs, bassoon and the tubule of different size and different length can be selected, be more conducive to heat exchange.
When designing, heat exchanger 2 integral sealing, be tightly connected between the deaerated water outlet 23 of heat exchanger 2 and the deaerated water import 21 of heat exchanger, the deaerated water outlet 11 of thermal deaerator 1 is also tightly connected with the deaerated water import 21 of heat exchanger 2, also be tightly connected between the deaerated water outlet 23 of heat exchanger 2 and boiler feed water mouth, can ensure that the deaerated water during heat exchange can not enter oxygen again, affect boiler quality.
In a word, the utility model does not need external heat energy, directly uses the heat exchange between high temperature deaerated water and outside normal temperature demineralized water to reach reduction deaerated water temperature, improves the object of demineralized water temperature, thus can reach good energy-saving effect.
Such as in use embodiments more of the present utility model, boiler does not use steam condensate (SC), and only use the demineralized water of temperature 20 DEG C as unique water source, oxygen-eliminating device flow of inlet water and water flow are substantially suitable.The deaerator feedwater of 20 DEG C is lowered the temperature to the oxygen-eliminating device water outlet of 105 DEG C, and the oxygen-eliminating device water outlet of 105 DEG C simultaneously is also carrying out heat temperature raising to the deaerator feedwater of 20 DEG C.When middle operating mode, when oxygen-eliminating device leaving water temperature is reduced to 62.5 DEG C, the inflow temperature of oxygen-eliminating device also can be elevated to 62.5 DEG C.In this case, the steam consumption of thermal deaerator can reduce about one times than the consumption of common thermal deaerator.For aforementioned 10 tons/time boiler, the quantity of steam that its thermal deaerator consumes can by 1.5 tons/time be reduced to 0.8 ton/time about, user can the actual quantity of steam used also can by 8.5 tons/time rise to 9.2 tons/time more than.Under extreme case, as long as heat exchanger heat exchange area is enough, just oxygen-eliminating device inflow temperature can be brought up to about 90 DEG C, leaving water temperature is reduced to about 35 DEG C, the steam consumption quantity of oxygen-eliminating device can be reduced to original about 20%.
Embodiment of the present utility model has following beneficial effect: 1, lowers the temperature, just the leaving water temperature of thermal deaerator can be reduced to about 60 DEG C with the deaerator feedwater of temperature 20 DEG C to the oxygen-eliminating device water outlet that temperature is 105 DEG C.The exhaust gas temperature of boiler can be reduced to about 100 ~ 110 DEG C like this, both reach energy-conservation effect, also can avoid the acid dew-point temperature between 95 ~ 100 DEG C, thus avoid the acid corrosion of boiler low-temperature heating surface.2, when the deaerator feedwater of temperature 20 DEG C is lowered the temperature to the oxygen-eliminating device water outlet that temperature is 105 DEG C, temperature is that the oxygen-eliminating device water outlet of 105 DEG C is also heating up to the deaerator feedwater of temperature 20 DEG C, thus the water temperature entering oxygen-eliminating device can be elevated to about 60 DEG C, therefore, after application the utility model carries out reducing energy consumption to thermal deaerator, the steam consumption of thermal deaerator can lower one times than common thermal deaerator.
