化工厂大聚丙烯装置生产使用蒸汽由总厂动力厂供给，1.0MPa中压蒸汽经减压至0.4MPa@150℃的低压蒸汽。蒸汽连续加热设备有8台，连续加热夹套有三处，伴热蒸汽管线（含仪表伴热）127条，蒸汽消耗量为2.6～3.5t/h。
Large polypropylene chemical equipment for production use steam by the factory power supply, 1.0 MPa medium-pressure steam by the reduced pressure 0.4 MPa @ 150 ℃ of low pressure steam. Steam for heating equipment 8 units, heating jacket for three, heating steam pipeline (including instrument heating) 127, steam consumption is 2.6 ~ 3.5 t/h.
本装置的蒸汽凝结水采用了开式加压回收方式。蒸汽输送管线和蒸汽加热设备在凝结水出口安装疏水阀排水阻汽，是最简单最有效的节能方式。由于工作原理和各厂家制造工艺的不同，使疏水阀的质量参差不齐，使用寿命长短不一，加上维护检修不及时，疏水阀的排水阻汽功能得不到有效发挥，使蒸汽出现一定的损耗，并伴随一定程度的水击；同时，蒸
汽凝结水没有很好的利用，造成一定程度的浪费。我们结合本装置的实际情况，以及Armstrong公司生产的疏水阀的工作原理及性能的了解，提出大聚蒸汽凝结水的改造建议。
This device of the steam condensate adopted open pressure recovery methods. Steam pipeline and steam heating equipment in the condensate export vapor barrier installed steam trap is the easiest and most effective way of energy saving. Manufacturers due to the working principle and the manufacturing process is different, the trap of variable quality, the service life of the different length, coupled with insufficient maintenance, steam traps can not get effective drainage vapor barrier function, make the steam in a certain loss, and with a certain degree of water hammer; Not good to use at the same time, steam condensate, causing a certain amount of waste. We combined with the actual situation of this device as well as Armstrong steam traps produced by our company's principle of work and performance, large gathering steam condensate modification Suggestions are put forward.
1、装置蒸汽凝结水改造前的状况
象棋入门教程从零开始1, before the plant steam condensate
本装置的蒸汽凝结水采用了开式加压回收方式,实际情况是:P603至PK501、P603至FIC501、FIC502、P603至大环夹套、P603至挤压D806这些由于各种工艺原因没有使用,只有用作给界区蒸汽降温和自身循环。
The devices of the steam condensate adopts the open pressure recovery way, the reality is: P603, PK501 P603 FIC501, FIC502, P603, large ring jacket P603 extrusion D806 these is not used due to various reasons, only used for battery limit cycle steam cooling and itself.
本装置高压丙烯回收塔T301底部再沸器E303所用热能在开工初期是直接用蒸汽加热汽蒸罐D501洗涤塔T501的循环水,然后通过T501循环泵P501输送至E303,这股蒸汽是由控制阀FIC504控制的,流量为200Kg/h,时间为6小时。生产正常后FIC504关闭,由FIC501、FIC502
两股蒸汽冷凝液提供热量，而这两股蒸汽会夹带大量聚丙烯粉末到T501循环水系统,造成E303结垢,从而影响高压丙烯的洗涤效果。
This device of high pressure propylene recovery tower T301 E303 reboiler at the bottom of the heat energy at the beginning of the start is used directly in steam heating steam pot scrubber D501 T501 circulating water, and then through P501 conveying through E303 T501 circulating pump, the steam is controlled by the control valve FIC504, flow rate of 200 kg/h, the time is 6 hours. Production FIC504 after the normal close, is provided by FIC501, FIC502 two steam condensate heat, and these two steam entrainment of polypropylene powder to T501 circulating water system, causing E303 scale, thus affecting high-pressure washing effect of propylene.
CO汽提塔T701塔底再沸器E702直接用蒸汽加热,凝结水出口没有安装蒸汽疏水阀,直接用调节阀FIC711控制。这股蒸汽流量大约为350Kg/h。调节阀都有一定的泄漏量,而且没有汽水分离功能,从而导致蒸汽进入凝结水系统,产生较大水击。水击会严重损坏管道弯头,阀门等管道附件。我装置蒸汽凝结水线多次穿孔,补焊过5次。
T701 CO stripping tower bottom reboiler E702 directly with steam heating, the condensate export is not installed steam trap, with regulator FIC711 control directly. The steam flow rate is about 350 kg/h. Regulating valve have some leakage, and there is no separation of functions, leading to steam into the condensate system, result in the waters. Water hammer can severely damage the pipe elbow, valve and pipe accessories. I plant steam condensation water multiple perforation, repair welding for 5 times.
2、蒸汽凝结水节能创效的改造方案

2.1更换疏水阀
2.1 replace the drain valve

天蝎座性格根据本装置的实际情况和Armstrong公司生产的疏水阀的性能，我们同意对原有疏水阀进行更换，使用Armstrong公司生产的疏水阀。
According to the actual situation of this device and the performance of Armstrong steam traps produced by our company, we agree to replace the original steam trap, using the Armstrong steam traps produced by our company.
2.2改造方案
2.2
经过几年的摸索和实践,我们对蒸汽凝结水的改造形成了以下方案：加压泵P603更换成大流量的水泵,在P603出口新增出口管线两条,一条提供高压丙烯回收塔T301底部再沸器E303所需热能,另一条提供CO汽提塔T701塔底再沸器E702所需热能，这两股流量通过控制阀控制，控制阀可利旧。回流线上通入一股蒸汽,用于开工初期,保证开工时E303的热量需要。这股蒸汽用控制阀控制,控制阀可以利旧,即使用FIC504,正常生产时该阀关闭。
After several years of exploration and practice, we formed the following plan: for the modification of the steam condensate pump P603 change into big flow of the pump, the P
603 two new export pipeline, and a provide high propylene recovery tower T301 E303 reboiler at the bottom of the required heat energy, another offer T701 CO stripping tower bottom reboiler E702 needed to heat energy, which flow through the valve control, control valves can be old. Online access to a steam, for early starts, the guarantee starts when E303 calorie needs. The steam control valve control, control valves can be old, namely using FIC504, normal production when the valve is closed.
