定期/連續(xù)排污擴(kuò)容器是與鍋爐的定期/連續(xù)排污口連接的，是用來對(duì)鍋爐的定期/連續(xù)排污進(jìn)行減壓擴(kuò)容，使排污水在定期/連續(xù)排污膨脹器內(nèi)絕熱膨脹分離為二次蒸汽和廢熱水。排污水在擴(kuò)容器內(nèi)經(jīng)擴(kuò)容、降壓、熱量交換，產(chǎn)生的廢熱水被排放，產(chǎn)生的二次蒸汽由專門的管道引出。定期/連續(xù)排污量隨鍋爐給水負(fù)荷變化自動(dòng)調(diào)節(jié)，保持相對(duì)穩(wěn)定的排污率。

The periodic/continuous blowdown expansion container is connected with the periodic/continuous blowdown outlet of the boiler. It is used to decompress and expand the periodic/continuous blowdown of the boiler, so that the the blowdown water in the periodic/continuous blowdown expander can be separated into secondary steam and waste hot water. The waste hot water is discharged after expansion, pressure reduction and heat exchange in the expanded container, and the secondary steam is drawn out by a special pipe. Continuous sewage discharge can be adjusted automatically with the change of boiler feed water load to maintain a relatively stable sewage discharge rate.
