Description
Technical field
The present invention relates to a kind of vapor pressure adapter, relate in particular to adjustable many nozzles vapor pressure adapter in the place that a kind of low pressure steam that is used for steam heating system need boost, it has improved the off design performance of vapor pressure adapter, has improved the heat energy utilization rate of steam heating system.
Background technique
Heat supply steam turbine is industrial a kind of engineering goods commonly used, pressure of steam supply in the use of heat supply steam turbine, often occurs and be lower than working pressure, can not satisfy the heating system needs, Chinese patent, the patent No. of the present patent application people Wang Ruwu is that 96238580.8 utility model patent " steam turbine pressure adapter " is with steam jet ejector and heat supply steam turbine cooperation, draw gas by the part of high speed nozzle injection steam turbine or lower pressure steam such as back pressure vapour with high pressure steam, make it to improve the requirement that pressure can satisfy various different vapor pressure users.But efficient obviously descended when the pressure matcher of this structure changed at steam flow, was lower than 50% o'clock of design discharge at flow, draws low pressure vapour not, and efficient is zero, has reduced the heat energy utilization rate.
Summary of the invention
Technical problem to be solved by this invention provides a kind of adjustable many nozzles vapor pressure adapter, and it has overcome the low shortcoming of above-mentioned steam turbine pressure adapter heat energy utilization rate, has improved the heat energy utilization rate of steam power system.
In order to address the above problem, the present invention is achieved in that its structure comprises the pressure matcher housing, nozzle, vaporium, mixing chamber, drive steam inlet, suck steam inlet, it is characterized in that being provided with in the pressure matcher housing 2 above spargers, each sparger is to be made of a nozzle and a corresponding mixing chamber and diffuser that is provided with thereof, each nozzle correspondence is provided with modulating valve, the length difference of the valve rod of each modulating valve, the valve rod of each modulating valve with carry plate and be slidingly connected, carrying plate is connected with lifting arm, each mixing chamber is provided with suction steam inlet separately, and an end of the nozzle of each sparger is connected with vaporium.
The spread pattern of above-mentioned sparger more than 2 can be rectangular, circle, polygonal or other shape.
The end of above-mentioned valve rod is provided with nut, and nut is used to control the interval of each opening of valves.
The size of above-mentioned each nozzle can be the same or different.
Advantage of the present invention and effect are: the present invention has improved the heat energy utilization rate of steam power system, and is simple in structure, easy to use, has extensive market prospects, is beneficial to enforcement.Vapor pressure adapter with four nozzles is an example, and the adapter of single nozzle relatively draw gas coefficient such as following table:
| Valve opening | Four nozzles | Four nozzle standard-sized sheets | Three nozzle standard-sized sheets (nozzle is closed) | Two nozzle standard-sized sheets (two nozzles are closed) | A nozzle standard-sized sheet (three nozzles are closed) |
| Single nozzle | The nozzle standard- | 3/4 | 1/2 | 1/4 aperture | |
| Coefficient draws gas | Four nozzles | 100％ | 100％ | 100％ | 100％ |
| Single nozzle | 100％ | 50％ | 0 | 0 |
