Continuous blowdown expansion vessel
Product overview
Continuous blowdown continuous drainage expansion device, and is connected to the boiler continuous blowdown, is used for continuous blowdown decompression and expansion of the boiler sewage in the continuous expansion of the sewage is separated into two adiabatic expansion of steam and the waste water, and in the expander is through expansion, pressure, heat exchange, and then discharge two, led by a special steam pipeline, the waste water discharged by the automatic float valve and relief valve, the heat energy can be recycled.
Two, working principle
Boiler sewage continuously and uniformly into the blowdown tank, tangential movement of cylinder separator sewage in the shell in the middle of the two, and immediately vaporized into steam, it passes through the upper separator louver type of separator, the row at the top of the export import except for oxygen, water and sewage left through the water level regulating valve discharge.
Three, product features
The continuous discharge quantity can be adjusted automatically with the change of the boiler water supply load, and the relatively stable discharge rate can be maintained. Therefore, the use of two steam and waste hot water as heat source, can recover part of the boiler continuous blowdown loss of heat, improve boiler efficiency
