Test example
As depicted in figs. 1 and 2,1 vapor-recovery system of spinning production definition device of the present embodiment includes: sizing pot, fixed
Connect by-passing valve on the gas exhaust piping 5 of type pot, gas exhaust piping 5 connects heat exchanger, the condensed fluid outlet of heat exchanger by pipeline with
Storage device connection.Gas exhaust piping 5 is equipped with the first control valve, and measures the flow of steam.The cooling water inlet of heat exchanger is set
There is the second control valve.The main control unit of vapor-recovery system controls the second control valve, 90 according to the flow of the steam of discharge
The steam of discharge is all recycled into condensation to 90 DEG C in second, and is recycled in storage device.Then fixed by metering water pump system
To adding to spinning recovery pipe 11, desalted water, the reduction recycle-water heating steam that recycling water system is added can be saved, and will
The solvent DMAC that steam is taken away in type-approval process is recycled, and is realized that steam overall process recycles, is improved efficiency of energy utilization.
It is 7.5 tons or so that condensing recovery water maximum, which can be obtained, by condensate recycling device 2 in the exhaust of sizing pot every time, therefore
Storage device can be the storage tank of one 15 cubic metres of volumes, the heat recovery water for collection belt DMAC.It is calculated by steam maximum
Recycle-water can reach 7.5 ton/hours after condensation, therefore one 10 is arranged on the pipeline between storage tank and spinning recovery pipe 11
Cubic meter force (forcing) pump and third control valve will be in storage tanks by the way of liquid level in storage tank and third control valve chain control
After heat recovery water carries out recycling collection, spinning recycle-water pipeline is squeezed into force (forcing) pump.
According to the condition calculating in existing workshop, annual process operation totally 8000 hours, wherein winter condition was about 3000
Hour.In winter, the water in spinning recovery pipe 11 is generally required begins to warm up from mean temperature for 5 DEG C, other seasons are with the summer
Ji Weizhu, 20 DEG C of coolant-temperature gage average out in spinning recovery pipe 11.In the vapor-recovery system of this programme, after steam condensation most
Greatly 5.5-7.5 ton/hours of 90 DEG C of recycle-waters containing DMAC can be provided for 11 process of spinning recovery pipe.By this calculating, under converting into
Come, if needing to consume steam 7.5t/h* (90 using original recycle-water in steam heating spinning recovery pipe 11 in winter
DEG C -5 DEG C) 1000/567Kcal/Kg*3000h=3373 tons of *, winter needs 3373 tons of steam.In summer, heated using steam
Original recycle-water in spinning recovery pipe 11 needs to consume steam 7.5t/h* (90 DEG C -20 DEG C) * 1000/567Kcal/Kg*
5000h=4629 tons, other seasons need 4629 tons of steam.Therefore, using vapor-recovery system of the invention, by shaping equipment
It putting into spinning recovery pipe 11 and reuses after recycling of condensed steam in 1, it is contemplated that whole year can reduce by 8002 tons of steam consumptions,
It is calculated by 140 yuan of steam per ton, whole year can save steam expense: 8002 tons * 140 yuan/ton=1,120,000 yuan.It therefore, can be factory
Area saves production cost, is conducive to improve productivity effect.
