Embodiment
High low pressure shaft seal vapour after back pressure turbine can do work by the utility model is extracted out, then the industry water in being restrained by cooling water cools steam, makes steam-reforming be liquid hydrophobic, and is unified to recycle by condensed hydrophobic carrying out.
The utility model selection thickness is that the A3 steel plate of 8 mm makes seal container 1; Seal container 1 inside goes out water chamber 11, water-inlet cavity 12 and adapter cavity 13 by baffle for separating.The brass tube that cooling water tube bank 10 is ф 16 mm by the many internal diameters be parallel to each other is formed, these brass tubes are divided into two groups, one group is connected between water chamber 11 and adapter cavity 13, another group is connected between water-inlet cavity 12 and adapter cavity 13, and water chamber 11 is connected with external refrigeration water lines with cooling water intake 5 respectively by the cooling water outlet 4 on seal container 1 sidewall with water-inlet cavity 12.The bottom of seal container 1 is provided with hydrophobic waste pipe 6, top is provided with shaft seal vapour entrance 2, sidewall is provided with air aspiration cavity 8, air aspiration cavity 8 to be fixed on seal container 1 by flange and to communicate with seal container 1, be fixed with diffuser pipe 7 and nozzle 9 respectively in the both sides of air aspiration cavity 8, the fumarole of nozzle 9 is relative with the suction port of diffuser pipe 7.
The effect of all parts is:
Seal container 1: be welded by cold rolled sheet is the place that hot and cold working medium carries out heat exchange.
Shaft seal vapour entrance 2: seamless steel pipe is welded, effect is delivered in seal container 1 by shaft seal vapour, to carry out cooling condensation to it.
Nozzle 9: punched pipefitting makes, and effect is that the high pressure steam stream making to pass through obtains comparatively kinetic energy.
Diffuser pipe 7: seamless steel pipe is welded.Effect is that air-flow is reduced by rear pressure, and the steam do not condensed is entered air.
Cooling water tube bank 10: brass tube embeds the steel plate after punching.Steam is in the flowing of copper pipe outer wall, and industry water is in the flowing of copper pipe inwall, and hot and cold working medium is completed can be exchanged.
