Description
Technical field
The utility model belongs to thermal power generating technology field, relates to a kind of Steam Turbine in Fire Power Plant exhaust steam heat recovering device.
Background technique
Thermal power plant is after merit finished by steam turbine, steam discharge (exhaust steam) heat is all discharged to air cooling (or clammy) vapour condenser condensation cooling, cause amount of heat waste, but also great impact is caused on environment, destroy the environment that the mankind depend on for existence, the theory of this and low-carbon environment-friendly, energy-saving and emission-reduction runs in the opposite direction.
On the other hand, in order to heating, need to extract out from steam turbine to also have the steam of acting ability, heating water is used for heat supply, and energy does not make full use of, and causes energy dissipation serious.
Model utility content
The utility model object is to overcome the deficiencies in the prior art, provides a kind of Steam Turbine in Fire Power Plant exhaust steam heat recovering device, is used for outward supplying heat by stream-jet ejector pumping unit turbine discharge, improves the energy, avoids energy dissipation.
For achieving the above object, the utility model by the following technical solutions:
A kind of Steam Turbine in Fire Power Plant exhaust steam heat recovering device, comprise steam turbine, stream-jet ejector and heating heat exchanger, the outlet of described exhaust steam in steam turbine is communicated with heating heat exchanger steam inlet by the stream-jet ejector for extracting exhaust steam in steam turbine, by stream-jet ejector pumping unit exhaust steam in steam turbine, with vapor mixing for heating heat exchanger provides heat.
Further, vacuum quick closing valve valve is installed between described heating heat exchanger and stream-jet ejector.
Further, between described stream-jet ejector and heating heat exchanger, pressure transmission device is installed.
Further, described heating heat exchanger water intake and water outlet are separately installed with the second valve.
Further, described heating heat exchanger is made up of lontitudinal series, multiple heat exchanger tube sheets laterally in parallel.
The utility model is for the present situation of current Steam Turbine in Fire Power Plant steam discharge (exhaust steam) heat loss, by penetrating vapour air extractor, with the steam that a part of parameter is higher, and mixed by stream-jet ejector pumping unit turbine discharge (exhaust steam), carry out heating water with mixed steam, be used for outward supplying heat; Namely make use of exhaust steam in steam turbine heat fully, and decrease the energy consumption of heating, improve capacity usage ratio, meet energy-saving and emission-reduction, the requirement of low-carbon (LC) life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-steam turbine; 2-stream-jet ejector; 3-heating heat exchanger; 4-vacuum quick closing valve valve; 5-pressure transmission device; 6-second valve.
