Abstract
The utility model discloses an evaporate cold ware with heater, including the pipeline of seting up the entry that draws gas to and set up the cooler side and heater side device at the pipeline both ends, utility model will evaporate cold ware and the heater unites two into one, reduce area greatly, and be convenient for arrange, the entering cooler that draws gas of steam turbine, the heating part feeds water before this, draw gas simultaneously and is lowered the temperature, after the cooling drawing gas through the orifice plate spread the heater further the firing equipment intake, realize the effect of former heater, the utility model discloses can not only realize steam cooler 's effect, can also replace former heater, have dual function to when using this equipment, need not use the critical hydrophobic pipeline of former heater can for steam cooler arranges critical hydrophobic pipeline alone.
Description
Technical field
This utility model belongs to thermal power generation unit and draws gas and heater system optimization field, is specifically related to a kind of steaming with heater
Cooler.
Background technology
Owing to the degree of superheat of thermal power plant's reheating embrittlement regenerative steam is relatively big, the irreversible loss produced in heat transfer process is the biggest.It is most
May reduce this loss, existing reforming mode is increase externally arranged steam cooler on the corresponding extraction line of unit, and steam cools down
Device is positioned on extraction line, and part feedwater enters boiler after steam condenser is heated, draws gas simultaneously and enters heating after being lowered the temperature
Inside device.On the one hand this mode properly increases the temperature of part feedwater, reduces effective heat transfer temperature difference of boiler, increases boiler efficiency,
Improve the heat-economy of unit；On the other hand reduce the degree of superheat of steam, namely reduce heat transfer temperature difference, improve unit further
Heat-economy.But increase externally arranged steam cooler at extraction line, not only individually to buy steam condenser, and owing to entering
The change of vapour parameter, high-pressure heater originally is the most undesirable, needs to buy new heater and changes.Meanwhile, the cloth of pipeline
Put difficulty to increase, the mainly emergent drain pipeline of steam condenser, cause system complexity to be greatly increased, it is contemplated that cost expenses
Reaching more than 1,000 ten thousand, cost is too high.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of steaming cooler with heater, it is possible to by heater and steaming
Cooler combines, and while realizing former function, the system that simplifies is arranged and greatly reduces cost.
In order to achieve the above object, this utility model includes that cooler side and heater side, cooler side and heater side are by offering
The housing exterior walls facial canal road having extraction entrance connects, and cooler side hydroecium offers feed-water inlet and feedwater outlet, and by the first water
Room dividing plate separates, and is connected by U-tube between feed-water inlet and feedwater outlet, and heater side hydroecium offers heater water inlet
With heater outlet, and separated by the second hydroecium dividing plate, between heater water inlet and heater outlet, pass through U-tube
Connecting, U-tube is placed in lateral steam tube road.
It is provided with the first orifice plate between the hydroecium of described cooler side and lateral steam tube road, is provided with between the hydroecium of heater side and lateral steam tube road
Second orifice plate.
Described extraction entrance is positioned close on the housing exterior walls facial canal road of cooler side.
The U-tube length of described cooler side is less than the U-tube length of heater side.
The U-tube of described cooler side and the U-tube of heater side are many groups.
Compared with prior art, steaming cooler and heater are united two into one by this utility model, substantially reduce floor space, and just
In layout, the entrance cooler that draws gas of steam turbine, heating part feedwater, drew gas simultaneously and was lowered the temperature before this, and drawing gas after cooling is passed through
Orifice plate is diffused into the water inlet of heater further firing equipment, it is achieved the effect of former heater, it is cold that this utility model can not only realize steam
But the effect of device, moreover it is possible to substitute former heater, has dual-use function, and when using this equipment, it is not necessary to for steam condenser
Individually arrange emergent drain pipeline, use the emergent drain pipeline of former heater.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
See Fig. 1, this utility model include cooler side and heater side, cooler side and heater side by offer draw gas into
The housing exterior walls facial canal road of mouth 3 connects, and cooler side hydroecium offers feed-water inlet 1 and feedwater outlet 2, and by the first hydroecium
Dividing plate 6 separates, and is connected by U-tube between feed-water inlet 1 and feedwater outlet 2, and heater side hydroecium offers heater and enters
The mouth of a river 4 and heater outlet 5, and separated by the second hydroecium dividing plate 9, heater water inlet 4 and heater outlet 5
Between connected by U-tube, U-tube is placed in lateral steam tube road, is provided with the first hole between the hydroecium of cooler side and lateral steam tube road
Plate 7, is provided with the second orifice plate 8 between the hydroecium of heater side and lateral steam tube road, extraction entrance 3 is positioned close to the shell of cooler side
On external wall pipeline, the U-tube length of cooler side less than the U-tube length of heater side, the U-tube of cooler side and
The U-tube of heater side is many groups.
Method of work of the present utility model, comprises the following steps:
Step one: draw gas and enter in lateral steam tube road from extraction entrance 3, carry out heat exchange with the feedwater in the U-tube of cooler side,
Drawing gas and lowered the temperature, feedwater enters boiler internal by pipeline after heating up；
Step 2: drawing gas after cooling is freely spread to heater side and heats the water inlet in the U-tube of heater side, adds
Heater water outlet after heat enters low-level device.
This utility model is by steam condenser and heater integration, and an equipment achieves the function of two equipment, need not individually set
Putting the emergent drain pipeline of steam condenser, simplify pipe arrangement, improvement cost is substantially reduced, and can reduce by 10% according to preliminary estimation.
