In Steam Turbine running, constantly to condenser steam discharge, most of units are all its low pressure (LP) cylinder final stage at present
The steam discharge that unit is condensed by surface-type heat exchanger using recirculated cooling water.Arrive when summer, when atmospheric temperature is higher,
In order to make up the deficiency of existing heat exchanger exchange capability of heat, often inside condenser cooling unit, install desalination water spray system additional, make
The unit steam discharge of demineralized water and high temperature realizes mixed heat transfer in condenser throat, under original quantity of circulating water and environment temperature, makes
Demineralized water evaporation endothermic is improving the vacuum of unit.
Existing desalination water spray system is the hole for opening up 3mm～5mm on filling pipe, when condenser needs moisturizing,
Current in filling pipe will be added in condenser with water column form, as water column flowing velocity is fast and heat exchange area is little, be caused
Demineralized water moisturizing condenser throat can not well with steam discharge mixed heat transfer, thus turbine discharge can not be promoted well
Condense.Some scholars fill into condenser after proposing to be atomized moisturizing, and to improve unit heat economy, but its technical scheme is still deposited
In certain deficiency, first, its scheme for being proposed is only when condenser needs moisturizing to be atomized moisturizing, therefore
The heat exchange situation of unit steam discharge can only be improved in certain time period (small range)；Secondly, if condenser is constantly in normally
Water level, condenser do not need moisturizing, then atomising device does not only have the effect for improving vacuum, can also make unit steam discharge on the contrary
Flow field changes, and causes unit vacuum further to deteriorate；3rd, the Steam Turbine in reality is often uninterruptedly run
, its unit steam discharge is also continual, and therefore, it is low that existing technical scheme can not fundamentally solve condenser vacuum
Problem.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided a kind of generating set steam discharge cooling device,
Thoroughly solve the problems, such as that condenser vacuum is low, improve the heat-economy of unit.
Problem described in the utility model is solved with following technical proposals：
A kind of generating set steam discharge cooling device, composition include that sweet-water tank, condenser, water pipeline, condenser are cold
But pipe, cooling water pump and condensate circulating pump, the head end of the water pipeline by cooling water pump absorption sweet-water tank in removing
Salt solution, the throat of tail end insertion condenser are simultaneously provided with atomizer, and the Cooling Tubes of Condenser is under the throat of condenser
Side, the water inlet of the condensate circulating pump connect the drainpipe of condenser, and delivery port is connected with sweet-water tank by pipeline.
Above-mentioned generating set steam discharge cooling device, the condensate circulating pump are provided with heat with the connecting line of sweet-water tank
Pump assembly, the source pump are connected with source pump working medium pipeline by source pump working medium circulating pump.
Above-mentioned generating set steam discharge cooling device, the atomizer setting on the water pipeline are multiple, and they are in condensing
It is uniformly distributed on the horizontal cross-section of device throat.
The utility model is continuously sprayed onto in condenser after desalination is cooled down water atomization, makes demineralized water and generator
Exchanged heat between group steam discharge incessantly, compensate for the deficiency of Cooling Tubes of Condenser exchange capability of heat, the utility model is from basic
On solve the problems, such as that condenser vacuum is low, improve the heat-economy of unit.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, generating set steam discharge cooling device that the utility model is adopted include sweet-water tank 1, condenser 6,
Cooling Tubes of Condenser 5 inside condenser 6, the water pipeline 2 installed in 5 upper area of Cooling Tubes of Condenser, installation
Atomizer 3, condensate circulating pump 7 on water pipeline 2, source pump 8, cooling water pump 4, source pump working medium circulating pump
9th, heat exchanger 10.Wherein, water pipeline 2 by be connected to 6 inwall of condenser bracing frame support, atomizer 3 is at a certain angle
On water pipeline 2.
The quantity of water pipeline 2 and atomizer 3 according to cooling water inflow number be determined, water pipeline 2 and atomization
Installation of the nozzle 3 in 6 throat of condenser and arrangement mode are determined according to the actual optimization result of calculation of different units.
Generating set steam discharge coolant mechanism：
In Steam Turbine running, the demineralized water in sweet-water tank 1 is continuously transported to spray by cooling water pump 4
In waterpipe 2, then the throat of condenser 6 after being atomized through atomizer 3, is sprayed at, is made between demineralized water and generating set steam discharge not
Discontinuously exchanged heat.With the entrance and the condensation of steam discharge of demineralized water, condenser water level will be gradually increasing, when condenser water level
When exceeding setting value, start condensate circulating pump 7, the demineralized water and condensate in condenser 6 passes sequentially through condensate circulating pump 7
Sweet-water tank 1 (and then recycling in water pipeline 2 is transported to by cooling water pump 4 again) is entered with source pump 8, is reducing coagulating
The cooling of condensate is realized while vapour device water level.The low-temperature receiver of wherein source pump 8 comes from source pump working medium circulating pump 9.
After source pump 8 absorbs heat from condensate, absorbed heat is released to heat exchanger 10.
The utility model has advantages below：
(1) desalination cooling water continuously sprays into condenser in condenser throat after atomization, when unit normally runs,
Can be exchanged heat incessantly between cooling water and steam discharge, greatly increase the displacement of condensation, so as to improve main condensation
The thermic load in region, this are highly significant to improving unit vacuum and improving unit heat economy.
(2) condensate circulating pump is extracted out condensate and exchanged heat from outside source pump working medium, reduce solidifying
The temperature for bearing water, it is effectively guaranteed that cooling effect of the demineralized water to unit steam discharge.
(3) absorbed heat is discharged in coal unit heat exchanger, effectively after source pump is absorbed heat from condensate
Reduce the coal consumption of coal unit.
(4) the cooling water and unit steam discharge mixing after being atomized, after steam discharge cooling is condensed, it is easy to by the sky in condenser
Air elutriation goes out, and not only can improve the operating efficiency of air-extractor, and can improve cooling tube and unit steam discharge in condenser
Heat transfer effect,, to improving unit vacuum, it is very effective to improve its heat-economy for this.
Above-described embodiment is only the preferably several embodiments of the utility model, is not intended to protect the utility model
The restriction of scope, on the premise of without departing from the utility model core technology, this area ordinary skill technical staff is to this practicality
Various equivalent variations or improvement that new technique scheme is made, all should fall within protection domain of the present utility model.
