Description
Technical field
This programme is related to a kind of device that power plant voluntarily drives cooling water to recycle using exhaust steam, belongs to steam power plant's circulation
Cooling water field of energy-saving technology.
Background technique
The high steam of steam power plant's production pressure after power generation is lowered, and energy is released in the form of pressure, but
It is the pressure that the later exhaust steam of power generation still has 4-5kg, corresponding thermal energy is still very high at this pressure, but cannot be direct
For generating electricity, in winter, these thermal energy can be used effectively to heat to cities and towns, but can not just utilize to summer and autumn
If emptying will increase the fuel factor of atmosphere, directly sent out although someone has developed using the exhaust steam under the pressure state
The device of electricity, but due to being costly and inefficient, so practical application value is little.The currently used method using exhaust steam
The method of mainly cooling recycling hot water, there are also be exactly the method to be recovered energy using heat pump principle；Cooling absorption method is with cold
But water is cooling these exhaust steam, becomes and is delivered to boiler with high-pressure pump again after condensed water and reheats utilization, not only returns in this way
Distilled water has been received, and a part of heat can also be recycled, has been at present using most common method；But it is led since cooling water is heated
Temperature is caused to increase, so also cooling water is transported to above cooling tower by pump, then spraying cooling is recycled, which can disappear
Consumption largely follows cooling ring water and electric energy, then corresponding heat does not utilize not only under the pressure of 4-5kg and the pressure, and
And these energy are also destroyed with a large amount of recirculated water, but also need the cooling device that exchanges heat.People utilize heat in recent years
Pump principle can be directly used for special steam turbine power generation, energy the energy that can be done work is become after low-pressure steam recompression heating
Amount is destroyed less, however heat pump investment is big complicated for operation, and compressor therein also needs to consume a large amount of electric energy, and people are again thus
It further creates using jet type heat pump and replaces compressor, such as " a kind of 2008101022248 recycling steam power plants are cold for patent
The steam jet heat pump of solidifying waste heat " has certain energy-saving significance, but jet pump equally consumes electric energy, and operation is also cumbersome, because
This for many years people seek always wish to find out power plant directly utilize exhaust steam do work method or apparatus, there is an urgent need to throw
Provide that small, low energy consumption, exhaust steam easy to operate is using device.
Summary of the invention
In order to solve the problems, such as that cooling absorption method and the investment of heat pump method are big, energy consumption is high and complicated for operation, this programme is provided

Enter extension airbag 4, steam condensate (SC) is then the outside that main tank body 1 is expelled to by air bag connecting tube 7.In the top of main tank body 1
There is a solenoid valve shutdown signal generator 12, there is a circulating water inlet 2 and a recirculated water water outlet outside top respectively
Pipe 11 is respectively equipped with exhaust steam pipe 5 and steam condensate (SC) outlet 9 in the bottom outer of main tank body 1；Exhaust steam pipe 5 is connected with useless
Steam electromagnetic valve 6 and check valve 302 are used between exhaust steam solenoid valve 6 and solenoid valve shutdown signal generator 12 and are electrically connected, when
When touched when extension airbag 4 extends to the solenoid valve shutdown signal generator 12 at the top of main tank body 1, solenoid valve shutdown signal occurs
Device 12 can issue cut-off command, and exhaust steam solenoid valve 6 is closed to stop being passed through into main tank body 1 at this time；It is described useless
Steam electromagnetic valve 6 is electrically connected with solenoid valve open signal generator 10, when the top of extension airbag 4 bounces back to a certain extent
When touching solenoid valve open signal generator 10, solenoid valve open signal generator 10 can issue open command signal at this time,
So that steam electromagnetic valve 6 is opened, exhaust steam is passed through to main tank body 1 again.It is unidirectional that the circulating water inlet 2 connects heat recirculated water
Valve 301, effect are only heat recirculated water to be allowed to enter main tank body 1, without allowing to recycle aqueous reflux, are connected on circulating water outlet pipe 11
It is connected to heat recirculated water check valve 303, only allows heat recirculated water that main tank body 1 is discharged, is connected with gas on steam condensate (SC) outlet 8
Liquid/gas separator 10, function are that only discharge condensed water is discharged without permission vapor.Main tank body 1 combines the assembly of extension airbag 4
It should be used in conjunction in combination with frequency variable circulating pump, the purpose in conjunction with frequency variable circulating pump is to adjust main tank body 1 by multiple groups parallel connection
Pressure oscillation.
The utility model has the advantages that main tank body combination extension airbag, conveys recirculated water using the pressure of exhaust steam, eliminates part circulation
Pump, while exhaust steam can be cooled into condensed water again and achieve the purpose that recycling；By the main tank body of multiple parallel connections and flexible
The entirety of air bag opens and closes the device of signal generator in conjunction with check valve, steam electromagnetic valve, solenoid valve, by exhaust steam
Pressure is applied on extension airbag, is played the role of conveying recirculated water, is eliminated part circulating pump, and be cooled to exhaust steam
For condensed water, while exhaust steam can be cooled into condensed water again and achieve the effect that recycling, achieve the purpose that recycling,
The temperature-fall period first exhaust steam with a large amount of cooling water failure energies is eliminated, directly acting economize on electricity is obvious.
