Abstract
This utility model provides a kind of steam turbine generator jetting circulation, including jetting case, water-blaster, condenser；The jetting case is connected with water-blaster, is provided with closed circuit and is connected to jetting case on water-blaster, and the condenser is connected to water-blaster, and the condenser two ends are provided with condenser vacuum pipeline, and the jetting case is connected to condenser vacuum pipeline on condenser.The water circulating pump water is connected on condenser cooling water outlet conduit.High-temperature water in jetting case is transported to after circulation water station cools by condenser recirculated cooling water outlet conduit and returns condenser by this utility model, it is ensured that in plant running, water temperature is constant and recycles, and avoids row outside recirculated water, reduces the waste of water.
Description
Technical field
This utility model is related to a kind of steam turbine generator jetting circulation.
Background technology
At present, domestic steam-electric power unit condenser jetting vapor extraction device technological process is：Mended to jetting pond with industry water
Water, makes pool inner water position maintain certain altitude, and pool inner water pressurization is sprayed at a high speed water-jetting steam extractor using water-jet pump.By at a high speed
The ejector principle of current, makes vacuum is formed in water-jetting steam extractor, and water-jetting steam extractor is connected with condenser air pipe.Using jetting
The high-velocity flow of pump extracts the incondensable gas of condenser out, to maintain condenser inner height vacuum.Project from water-jetting steam extractor
Industry water is returned in jetting pond together with the acting exhaust steam (water) in condenser, is drawn gas process so as to complete whole jetting.This
Have the disadvantage in planting process that water system closing cannot be lowered the temperature, water temperature slowly can be raised, when water temperature is more than 50 DEG C, water-jet pump
Work efficiency will substantially reduce, directly affect Steam Turbine Condenser Vacuum degree, and then affect unit generation amount.Work is taken only
The method of industry moisturizing is lowering the temperature.And unnecessary water resource is directly drained from overflow pipe, a large amount of wastes of water resource are caused.
Utility model content
To solve above-mentioned technical problem, this utility model provides a kind of steam turbine generator jetting circulation.
This utility model is achieved by the following technical programs.
A kind of steam turbine generator jetting circulation that this utility model is provided, including jetting case, water-blaster, condensing
Device, water circulating pump；It is characterized in that：The jetting case is connected with water-blaster, is provided with closed circuit and is connected to and penetrate on water-blaster
Water tank, the condenser are connected to water-blaster, and the condenser two ends are provided with condenser vacuum pipeline, the jetting case connection
Condenser vacuum pipeline on condenser.The water circulating pump is connected on condenser cooling water outlet conduit.
Also be disposed with pipeline between the jetting case and condenser recirculated cooling water outlet conduit water circulating pump,
Electric control valve, check-valves.
The beneficial effects of the utility model are：High-temperature water in jetting circulating box is passed through into condenser circulating cooling water pipe
Return in water-blaster water tank and in condenser after the defeated cooling to circulating cooling water station in road, it is ensured that in plant running, circulating water temperature is permanent
It is fixed, and row outside recirculated water is avoided, reduce the waste of water.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- jetting casees, 2- water-blasters, 3- condensers, 4- check-valves, 5- electric control valves, 6- water circulating pumps, 7- coagulate
Vapour device vacuum pipe, 8- condenser cooling water water inlet pipes, 9- condenser cooling water water inlet pipes, 10- jetting case filling pipes.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
Including jetting case 1, water-blaster 2, condenser 3, water circulating pump 6；The jetting case 1 is connected with water-blaster 2, water-blaster
Closed circuit is provided with 2 and is connected to jetting case 1, the condenser 3 is connected to water-blaster 2, and 3 two ends of the condenser are provided with
Condenser vacuum pipeline 7, the jetting case 1 are connected to the condenser vacuum pipeline 7 on condenser 3.The water circulating pump 6 connects
On 3 cooling water outlet pipe road of condenser.
Recirculated water is disposed with also on pipeline between the jetting case 1 and condenser recirculated cooling water outlet conduit 9
Pump 6, electric control valve 5, check-valves 4.
During operation the water of jetting case 1 by increase water circulating pump 6 water in jetting case 1 is drawn into condenser circulate it is cold
But the high-temperature water in jetting case 1 is lowered the temperature in waterpipe 9, check-valves 4 prevent high-temperature water to be back in jetting case, electric adjustable
Section valve can be adjusted to quantity of circulating water according to the temperature in the load of condenser 3 and jetting case 1, it is to avoid 3 load of condenser
Condenser operation is affected again, is made the water temperature in jetting case reduce by 20 degree or so, be increased negative pressure (absolute pressure), prevent recirculated water
Outer row, improve generating efficiency.
