Description of drawings
Fig. 1 is the sectional drawing of vapour system according to an embodiment of the invention; And
Fig. 2 is the sectional drawing of traditional vapour system.
Embodiment
Shown in Figure 1 is the sectional drawing of vapour system, and it for example is how to be used for alkene to obtain equipment.At this, identical or corresponding assembly with traditional vapour system of Fig. 2 adopts identical reference character.
To be about 70 ℃ softened water and condensed water (unified be called feedwater) from the temperature of vapour system through quantity delivered for example be to be up to 1000 tons/hour feedwater piping 10 to send into vapour system.After the heating in advance, feedwater continues to be heated to boiling point in low pressure deaerator 16, and is used to carry out stripping from the steam of vapour system in preheater 12 and 14, to carry out degassing processing, in other words, removes and is dissolved in gas wherein, like oxygen and nitrogen.Use softened water and especially do not corroded in particular for protection apparatus assembly and pipeline through the water of degasification.
To send into second preheater 14 and low pressure deaerator 16 as the heat exchange medium that is used for heated feed water from the water vapor of vapour system, wherein working pressure all is in the first stress level P1 that is higher than atmospheric pressure a little at steam side, for example is approximately 1.5 crust.
Utilize pump 18 to send into unshowned steam generator from deaerator 16 through pipeline 20 through the feedwater of degasification.In this steam generator, make softening feedwater change into overheated steam with degasification.
This overheated water vapor gets in the low pressure steam pipeline 22 with working pressure that is in the second stress level P2 that is approximately 6.5 crust and the operating temperature that is approximately 240 ℃.This low pressure steam pipeline 22 distributes at steam side water vapor to be up to the technology load device 24 of working pressure work of about 6.5 crust.This technology load device 24 mainly is a heat exchanger.The water vapor of the second stress level P2 that is approximately 25 tons/hour is provided to technology load device 24 in the embodiment in figure 1.
Will be in technology load device 24/condensed water locating to produce sends into condensate collector 26.The condensed water that will produce at first preheater, 12 places is also sent into this condensate collector 26.Finally utilize pump 28 for example to send condensed water back to this system again from condensate collector 26 through pipeline 30 through feedwater piping 10.
Water vapor from vapour system is also sent into condensate collector 26 as heat exchange medium, and wherein working pressure is in the first stress level P1 that is approximately 1.5 crust at steam side.Water vapor is continued to guide to first preheater 12 from condensate collector 26, thereby the feedwater in the feedwater piping 10 is heated at this.
In addition, overheated water vapor gets in the high pressure steam pipeline 38 with working pressure that is in the 3rd stress level P3 that is approximately 45 crust and the operating temperature that is approximately 400 ℃ in steam generator.This high pressure steam pipeline 38 is to the overheated water vapor of a plurality of steam turbine that is connected in parallel 40 supplies.In these steam turbines 40, water vapor is depressurized to the first stress level P1 that is approximately 1.5 crust from the 3rd stress level P3 that is approximately 45 crust.
Change into kinetic energy corresponding to this steam enthalpy difference that is about the pressure drop of 43.5 crust at this, preferably rotate ability.So can drive one or more units that are connected with steam turbine 40 or machine (not shown), for example pump, compressor, blower etc. through this kinetic energy.The generator of at least a portion electricity needs that can satisfy said equipment can also be driven, thereby the external drive energy requirement amount of said equipment can be obviously reduced.
Also being present in steam side in the equipment to be up to the technology load device 24 of working pressure work of about 1.5 crust if obtain at alkene, can be that this technology load device 24 is supplied water vapors from minimum pressure steam line 42 also then.The water vapor that in the embodiment in figure 1, will be up to first about 25 tons/hour stress level P1 is supplied to technology load device 24 through minimum pressure steam line 42.
Because steam turbine 40 can not satisfy the demand for the water vapor of the first stress level P1 always; So being in the low pressure steam pipeline 22 of the second stress level P2 that is approximately 6.5 crust with its working pressure in addition, minimum pressure steam line 42 is connected, wherein P3＞P2＞P1.At this, preferably come balance steam demand amount through the pressure regulator valve 44 between low pressure steam pipeline 22 and minimum pressure steam line 42.At this, when normal operation, preferably make to minimize from the steam flow that the second stress level P2 is depressurized to the first stress level P1 through pressure regulator valve 44.
In addition, generate the whole vapour system of balance through steam regulation.
Make full use of the bigger pressure drop between the 3rd stress level and first stress level through steam turbine 40, in steam turbine 40, transform more energy thereby steam flow required in the vapour system is reduced perhaps.Can obviously improve in this way vapour system and therefore whole alkene obtain the energy efficiency of equipment.
In the embodiment in figure 1, for example making 86 tons/hour water vapor is not to be depressurized to the second stress level P2 that is approximately 6.5 crust through steam turbine 40 from the 3rd stress level that is approximately 45 crust, but is depressurized to the first stress level P1 that is approximately 1.5 crust.If the equal efficiency of supposition steam turbine 40 for example is about 60%, then it needs about 48 tons/hour water vapor less.
In addition; In the embodiment in figure 1; For example sending into to technology load device 24 and amount to about 50 tons/hour water vapor, is that deaerator 16, second preheater 14 and condensate collector 26 supplies amount to 61 tons/hour water vapor by minimum pressure steam line 42 to other assemblies simultaneously.
In the above embodiments, all supply the water vapor that is in the first stress level P1 that is approximately 1.5 crust to low pressure deaerator 16, second preheater 14 and condensate collector 26.If the increase of tolerance vapour system complexity then is depressurized to lower stress level and will only be used for low pressure deaerator 16 at this required superpressure P1 through the water vapor that is used in the softening feedwater of preheating and can effectively utilize water vapor more.
