Accompanying drawing explanation
Fig. 1 is the profile of the vapour system according to one embodiment of the present of invention；And
Fig. 2 is the profile of conventional vapor system.
Detailed description of the invention
Fig. 1 show the profile of vapour system, and it is the most how in alkene acquisition equipment.Here, the assembly identical or corresponding with the conventional vapor system of Fig. 2 uses identical reference.
Softening water and condensed water (collectively referred to as feedwater) that temperature from vapour system is of about 70 DEG C send into vapour system through the feedwater piping 10 of conveying capacity for example, up to 1000 ton hour.In preheater 12 and 14 after heating in advance, feedwater continues to be heated to boiling point in low pressure deaerator 16, and utilizes the steam from vapour system to strip, and to carry out degassing processing, in other words, removes and is dissolved in gas therein, such as oxygen and nitrogen.Use and soften water and deaerated water in particular for protecting apparatus assembly and pipeline not to be corroded.
To send into the second preheater 14 and low pressure deaerator 16 from the water vapour of vapour system as the heat exchange medium being used for heating feedwater, wherein operating pressure is in the first stress level P1 of slightly higher than atmospheric pressure, the most about 1.5 bars at steam side.
Utilize pump 18 that through pipeline 20, deaerated feedwater is sent into unshowned steam generator from deaerator 16.In this steam generator, the feedwater of softening and degasification is made to change into overheated steam.
The operating temperature of this overheated water vapour operating pressure and about 240 DEG C to be in the second stress level P2 of about 6.5 bars enters in low-pressure steam pipeline 22.Water vapour is distributed to the technique load device 24 worked at steam side with the operating pressure being up to about 6.5 bars by this low-pressure steam pipeline 22.This technique load device 24 mainly heat exchanger.In the embodiment in figure 1, the water vapour of the second stress level P2 being about 25 ton hour is provided to technique load device 24.
By in technique load device 24/place produce condensed water send into condensate collector 26.The condensed water produced at the first preheater 12 is also fed into this condensate collector 26.Pump 28 is finally utilized such as to send again condensed water back to this system through feedwater piping 10 from condensate collector 26 through pipeline 30.
Water vapour from vapour system also serves as heat exchange medium and sends into condensate collector 26, and wherein operating pressure is in the first stress level P1 of about 1.5 bars at steam side.Continue to guide to the first preheater 12 from condensate collector 26 by water vapour, thus at this, feedwater in feedwater piping 10 is heated.
Additionally, the operating temperature of the operating pressure and about 400 DEG C that the most overheated water vapour is to be in the 3rd stress level P3 of about 45 bars enters in high steam pipeline 38.This high steam pipeline 38 supplies overheated water vapour to multiple steam turbines 40 being connected in parallel.In these steam turbines 40, water vapour is depressurized to the first stress level P1 of about 1.5 bars from the 3rd stress level P3 of about 45 bars.
It is about the steam enthalpy difference of pressure drop of 43.5 bars corresponding to this and changes into kinetic energy, preferably rotational at this.Then pass through this kinetic energy and can drive one or more unit being connected with steam turbine 40 or machine (not shown), such as pump, compressor, aerator etc..The electromotor of at least some of electricity needs that disclosure satisfy that described equipment can also be driven, such that it is able to significantly reduce the external drive energy requirement amount of described equipment.
The minimum pressure jet chimney 42 of the first stress level that steam turbine 40 is in about 1.5 bars in downstream with its operating pressure is connected.Water vapour is distributed to its operating pressure and is in the said modules of the first stress level at steam side by this minimum pressure jet chimney 42.Its especially low pressure deaerator 16 but it also may be the second preheater 14 and condensate collector 26.
If being also present in the technique load device 24 that steam side works with the operating pressure being up to about 1.5 bars in alkene acquisition equipment, then can also supply water vapour from minimum pressure jet chimney 42 for this technique load device 24.In the embodiment in figure 1, the water vapour of the first stress level P1 that will be up to about 25 ton hour is supplied to technique load device 24 through minimum pressure jet chimney 42.
Because steam turbine 40 can not meet the demand of the water vapour for the first stress level P1 always, so the low-pressure steam pipeline 22 of minimum pressure jet chimney 42 the second stress level P2 of being additionally in about 6.5 bars with its operating pressure is connected, wherein P3 ＞ P2 ＞ P1.Here, preferably carry out equilibrium vapor demand by the pressure-regulating valve 44 between low-pressure steam pipeline 22 and minimum pressure jet chimney 42.Here, preferably make the quantity of steam being depressurized to the first stress level P1 from the second stress level P2 by pressure-regulating valve 44 minimize when properly functioning.
Whole vapour system is balanced additionally, generated by regulation steam.
The bigger pressure drop between the 3rd stress level and the first stress level is made full use of, such that it is able to make quantity of steam required in vapour system reduce or convert more energy in steam turbine 40 by steam turbine 40.Vapour system and the energy efficiency of the most whole alkene acquisition equipment can be significantly improved in this way.
In the embodiment in figure 1, the water vapour such as making 86 ton hour is not the second stress level P2 being depressurized to about 6.5 bars by steam turbine 40 from the 3rd stress level of about 45 bars, but is depressurized to the first stress level P1 of about 1.5 bars.If assuming that the equal efficiency of steam turbine 40 e.g., about 60%, then its few water vapour needing about 48 ton hour.
In addition, in the embodiment in figure 1, such as send into the water vapour amounting to about 50 ton hour to technique load device 24, supplied the water vapour of 61 ton hour altogether simultaneously by minimum pressure jet chimney 42 to other assemblies i.e. deaerator the 16, second preheater 14 and condensate collector 26.
In the above-described embodiment, the water vapour of the first stress level P1 being in about 1.5 bars is all supplied to low pressure deaerator the 16, second preheater 14 and condensate collector 26.If the increase of tolerance vapour system complexity, then it is depressurized to lower stress level and superpressure P1 required at this is only used for low pressure deaerator 16 can more efficiently utilize water vapour by being used in the water vapour of the feedwater of pre-thermal softening.
