Technical field
The utility model is related to a kind of Air-Cooling Island systems, more particularly to a kind of to be used for Turbo-generator Set steam exhaust Direct Air-Cooled
Drag compensation formula Air-Cooling Island system, belong to Turbo-generator Set steam exhaust cooling technology field.
Background technology
The gross energy of fuel because chemically reacting incomplete, waste heat in addition to discharging, dissipating in the reactor in Turbo-generator Set
Heat generates certain energy loss during waiting, in steam turbine because of energy that mechanical friction, heat dissipation, gas leakage can also wait generations certain
Amount loss, and because the certain generator of the generations such as coil heating, rotor mechanical loss is imitated during electrical power generators are driven
Rate is lost, and passes through generator and energy is converted into except electric energy, and the energy for usually also having more than 50% must pass through steam turbine
Exhaust steam end cooling release is carried out in a manner of steam exhaust waste heat, to complete the closed process of Rankine cycle.
Although the heat of turbine discharge is largely waste heat, it is difficult to be utilized, since radix is big, equally with considerable
The energy saving space.Cold end system is commonly divided into clammy and air-cooled two major class, and wherein air cooling unit includes Direct Air-Cooled and indirectly again
Air-cooled two kinds of forms.For Direct Air-cooled Unit, due to designing, manufacturing and factors and the air cooling blower fan method of operation such as installation
And the influence of the reasons such as ambient wind, there are steam flow distribution unevenness, incondensable gas gathers, and air cooling heat radiator winter is caused to be tied
Ice, unit in summer undercapacity run the problems such as back pressure is higher throughout the year.
The related solution taken both at home and abroad at present, generally engineering level comparison fall behind, and there are headache doctor's heads
Foot pain cures the problem of foot, leads to the contradiction as existing for air cooling heat radiator dilatation and preventing freeze in winter.
Utility model content
In order to reduce direct air cooling system different lines because designing, making the drag characteristic difference brought with installation difference, solution
The problems such as certainly Direct Air-cooled Unit winter arranges individually antifreeze outstanding problem, and summer entirety vacuum capability is insufficient, the utility model
It is proposed a kind of drag compensation formula Air-Cooling Island system.
The technical solution of the utility model is as follows：
A kind of drag compensation formula Air-Cooling Island system, including turbine discharge pipeline, steam discharge distribution duct, air cooling heat radiator,
Condensate water collecting pipeline evacuates gas branch pipe road, evacuates feed channel main pipe and vaccum-pumping equipment and vaccum-pumping equipment isolating valve, special
Sign is：The installation and adjustment valve on each evacuation gas branch pipe road.
In the above-mentioned technical solutions, the system is also bypassed containing regulating valve, and the regulating valve bypass takes out air with each
Regulating valve on branch pipe(tube) is set up in parallel, and setting adjusts bypass valve in the bypass of each regulating valve.
The utility model compared with prior art, has the following advantages and the technique effect of high-lighting：1. the utility model
By the regulating valve on vacuum lead, the drag characteristic for each column air cooling heat radiator provides drag compensation means, so as to incite somebody to action
The drag characteristic of each row air cooling heat radiator is compensated to fairly horizontal, and the steam flow for making different lines air cooling heat radiator is evenly distributed,
Air-Cooling Island entirety cooling capacity is improved, and then the average coal consumption of unit can be reduced.2. by the raising of air cooling system cooling capacity,
The maximum output of unit is can further improve, especially improves the on-load ability under unit in summer sweltering heat weather.3. pass through resistance
Force compensating, the on-condensible gas that emphasis reduces indivedual row air cooling heat radiators gather situation, improve the resistance to frost of air cooling heat radiator.

Specific embodiment
The operation principle of the utility model, concrete structure and implementation are described further below：
Conventional air cooling island of air cooling unit system is as shown in Figure 1, it includes turbine discharge pipeline 1, steam discharge distribution duct
2nd, air cooling heat radiator 3, condensate water collecting pipeline 4, evacuation gas branch pipe road 5, evacuation feed channel main pipe 6, vaccum-pumping equipment 7 and pumping are true
Null device isolating valve 8；In the case, the steam exhaust of Steam Turbine initially enters steam discharge point after the discharge of turbine discharge pipeline 1
Distribution pipes 2, then a large amount of steam exhaust are condensed in air cooling heat radiator 3, are become condensed water and are entered through condensate water collecting pipeline 4
Condensate system.The a small amount of steam exhaust of remainder and incondensable gas are taken out very through evacuating gas branch pipe road 5 and evacuating feed channel main pipe 6
Empty set system (pumped vacuum systems includes vaccum-pumping equipment 7 and vaccum-pumping equipment isolating valve 8) extraction.
Fig. 2 is a kind of drag compensation formula Air-Cooling Island system provided by the utility model, it is in conventional Air-Cooling Island system
Increase regulating valve and regulating valve bypass, i.e., the installation and adjustment valve 9 on each evacuation gas branch pipe road 5, the regulating valve bypass with
Each regulating valve 9 evacuated on gas branch pipe road is set up in parallel, and setting adjusts bypass valve 11 in each regulating valve bypass 10.
The course of work of the utility model is as follows：The steam exhaust of Steam Turbine through turbine discharge pipeline 1 discharge after, first into
Enter steam discharge distribution duct 2, then a large amount of steam exhaust are condensed in air cooling heat radiator 3, become condensed water through condensate water collecting
Pipeline 4 enters condensate system.The a small amount of steam exhaust of remainder and incondensable gas are through evacuating gas branch pipe road 5 and evacuating feed channel mother
Pipe 6 is evacuated system (pumped vacuum systems includes vaccum-pumping equipment 7 and vaccum-pumping equipment isolating valve 8) extraction.The utility model
By vacuumizing setting regulating valve 9 on branch pipe(tube) 5 at every, to adjust the drag characteristic of each air cooling heat radiator sector, with to the greatest extent
Amount makes the evacuation tolerance of each sector close.It breaks down in regulating valve or when limited working condition system resistance difference is little,
Original state can be restored the system to by opening bypass valve, to reduce system resistance.
