Description
Technical field
The utility model is related to thermoelectricity field of energy-saving technology, more particularly to a kind of utilization air cooling unit exhaust steam cogeneration
Device.
Background technology
Energy loss in coal fired power plant includes that boiler exhaust gas radiating, condenser cooling water radiating, boiler blow-off, pipeline dissipate
Heat loss etc..In these thermal loss, having 50% or so is taken away by the cooling water in condenser, and ring is discharged into by cooling tower
In border, so as to cause energy largely to waste.For Air-cooled Unit, because exhaust steam pressure is high, exhaust steam temperature is high, make steam turbine steam discharge heat
Loss is higher.If the steam turbine exhaust steam residual heat of Air-cooled Unit is reclaimed being generated electricity, even if heat turns effect rate and there was only 2%, unit is whole
Body heat efficiency can also improve 1%.Therefore research and utilization steam turbine exhausted spare heat generates electricity very huge economic implications.
The content of the invention
For the problem for overcoming above-mentioned prior art to exist, main purpose of the present utility model is to provide a kind of using empty
The device that cold group exhaust steam residual heat generates electricity, to reduce the radiation loss in Air-cooled Unit air cooling tower, increases steam turbine and goes out work(, improves
Unit whole efficiency.
In order to achieve the above object, the utility model is adopted the following technical scheme that：
A kind of device of utilization air cooling unit exhaust steam cogeneration, including steam turbine 1, the exhaust steam with steam turbine 1 export phase
The condensation water out of the first air cooler 2 and evaporator 4 even, the first air cooler 2 and evaporator 4 is all connected with the condensation of circulating pump 3
Water inlet, the organic working medium entrance of the organic working medium outlet connection expanding machine 5 of evaporator 4, the organic working medium outlet of expanding machine 5 connects
The organic working medium entrance of the second air cooler 6 is connect, the organic working medium outlet of the second air cooler 6 connects the entrance of storage tank 7, storage tank 7
The entrance of the organic working medium pump 8 of outlet connection, the entrance of the outlet connection evaporator 4 of organic working medium pump 8.
The method that the above-mentioned device using air cooling unit exhaust steam cogeneration carries out cogeneration, the exhaust steam of steam turbine 1 is made
For organic working medium is heated to be superheated steam state by thermal source in evaporator 4 from liquid, the organic working medium of superheated steam state exists
Expansion work in expanding machine 5, by air-cooled condensation is liquid subsequently into the second air cooler 6, and condensed organic working medium is by having
After machine working medium pump 8 boosts, heated by steam turbine exhaust steam into evaporator 4, complete an organic working medium circulation；Organic working medium cyclic system
System is in parallel with coal unit original air cooling system, and when environment temperature is too high, the organic working medium circulatory system cannot be run, or organic work
When the matter circulatory system breaks down, first air cooler 2 of the steam turbine exhaust steam still into former air cooling system is condensed.
Due to taking system above allocation plan, it has advantages below to the utility model：
1st, the device and method of the utilization air cooling unit exhaust steam cogeneration that the utility model is provided, is followed by organic working medium
Loopback receives the exhaust steam residual heat of coal unit, and the effect of coal unit exhaust steam residual heat loss is reduced so as to reach.
2nd, the device and method of the utilization air cooling unit exhaust steam cogeneration that the utility model is provided, recyclable steam turbine is weary
Vapour waste heat is generated electricity, and coal unit generating efficiency is improved so as to reach, and reduces the effect of unit coal consumption.
3rd, the device and method of the utilization air cooling unit exhaust steam cogeneration that the utility model is provided, organic working medium cyclic system
System is in parallel with coal unit original air cooling system, and when environment temperature is too high, the organic working medium circulatory system cannot be run, or organic work
When the matter circulatory system breaks down, steam turbine exhaust steam still enters former air cooling system condensation, it is ensured that the stability of system.
Brief description of the drawings
Fig. 1 is schematic diagram of the utility model using air cooling unit exhaust steam device for generating power by waste heat.
Specific embodiment
Embodiment：
To make the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with specific embodiment, and
Referring to the drawings, the utility model is further described.
Illustrated by taking organic working medium R134a as an example.As shown in figure 1, the utility model one kind utilizes air cooling unit exhaust steam
The device of cogeneration, including steam turbine 1, the first air cooler 2 and evaporator 4 that the exhaust steam outlet with steam turbine 1 is connected, first
The condensation water out of air cooler 2 and evaporator 4 is all connected with the condensation water inlet of circulating pump 3, the organic working medium R134a of evaporator 4
The organic working medium R134a entrances of outlet connection expanding machine 5, organic working medium R134a outlet second air coolers 6 of connection of expanding machine 5
Organic working medium R134a entrances, the second air cooler 6 organic working medium R134a outlet connection storage tank 7 organic working medium R134a enter
Mouthful, the entrance of the organic working medium R134a outlet organic working medium pumps 8 of connection of storage tank 7, the outlet connection evaporator 4 of organic working medium pump 8
Entrance.
As shown in figure 1, the method that the utility model device carries out cogeneration, the exhaust steam of steam turbine 1 is being steamed as thermal source
Organic working medium R134a is heated to be superheated steam state from liquid in hair device 4, the organic working medium R134a of superheated steam state exists
Expansion work in expanding machine 5, by air-cooled condensation is liquid, condensed organic working medium R134a warp subsequently into the second air cooler 6
After crossing the boosting of organic working medium pump 8, heated by steam turbine exhaust steam into evaporator 4, complete an organic working medium R134a circulation；It is organic
