Abstract
The utility model provides a guide anti-freezing device of a power plant direct air cooling island. The guide anti-freezing device of the power plant direct air cooling island comprises guide plates and an upper baffle, wherein the upper baffle is horizontally arranged, the guide plates can rotate relative to the upper baffle, and an included angle between each guide plate and the upper baffle can be adjusted. Traction motors are fixedly installed on the upper baffle. Support seats are arranged on the guide plates. One end of each transmission chain is connected with each traction motor, and the other end of each transmission chain is connected with each support seat. When the environment temperature falls and the quantity of exhausted steam of a set decreases, the guide plates are enabled to fall, the included angle theta between each guide plate and the horizontal plane is gradually decreased until the guide plates are completely lowered and reach a first position, and an outlet is closed. When the environment temperature rises and the quantity of exhausted steam of a set is increased, the guide plates are enabled to rise, and the included angle theta between each guide plate 3 and the horizontal plane is gradually increased until the largest included angle theta is formed. Hot wind is prevented from returning, and therefore the heat exchange efficiency of an air cooling unit is improved. The operation method is rapid in response and good in heat preservation and sealing performance.
Description
Technical field
The utility model relates to a kind of power plant's Direct Air-Cooled island water conservancy diversion defroster, belongs to Power Plant cooling field.
Background technology
Compare traditional clammy fired power generating unit, adopt the mode of Air-Cooling Island Direct Air-Cooled can save water consumption, and do not exist and decide the problems such as factory site and capacity scale with water, thereby become gradually main flow in the northern China water-deficient area.
The Direct Air-Cooled mode is with the cooling medium of surrounding air as turbine discharge, surrounding air is directly heated after by the condenser of Air-Cooling Island, form negative pressuren zone when working due to blower fan at Air-Cooling Island bottom inlet place, heated component environment air can be sucked up to fans entrance and form the hot air reflux phenomenon, thereby reduce set heat exchange efficient, even cause turbine back pressure to raise fast, threaten the safe operation of unit.Hot air reflux is main relevant with the physical dimension of Air-Cooling Island, and the prophylactico-therapeutic measures of each power plant's employing at present is generally to build windbreak in the surrounding of air cooling platform, has obtained positive effect.In addition, hot air reflux and on every side depth of building and layout also have substantial connection, existing studies show that surrounding air can form the whirlpool district between air cooling platform and factory building, sucked Air-Cooling Island by blower fan behind gap between whirlpool district hot blast process Air-Cooling Island and steam turbine building, the meeting that affects of this hot air reflux phenomenon aggravates along with the increase of ambient wind velocity.
Very cold, the whole year and day and night temperature large area is built in the air cooling power station of China in more.In northern cold winter, low temperature can cause the even bursting by freezing of freezing of condenser large tracts of land accidents caused.At present the heat preserving method that usually adopts of power plant is to cover the cotton blanket insulation at the radiator outer surface, or adds the plug cotton blanket in the air inlet air channel and weaken circulation of air.Because the Air-Cooling Island space is large, there is the problem that labour intensity is large and cotton blanket easily is blown off in said method, and is difficult to play good heat insulation effect.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art and device, and a kind of Air-Cooling Island water conservancy diversion defroster reasonable, reliable, easy to adjust of constructing is provided.
To achieve these goals, the utility model provides a kind of power plant's Direct Air-Cooled island water conservancy diversion defroster, comprises the deflector and the overhead gage that are arranged on safety island top exit place, and overhead gage is horizontally disposed with, deflector can rotate with respect to overhead gage, and the angle between deflector and horizontal plane is adjustable; Deflector is closed described outlet when primary importance, open described outlet when leaving primary importance.
Be installed with traction electric machine on overhead gage, deflector is provided with bearing, and driving chain one end is connected with traction electric machine, and the other end is connected with described bearing.
Be installed with limiting plate between deflector and overhead gage, making variable angle scope between deflector and overhead gage is 0 °≤θ≤80 °.
Also comprise support and pillar, pillar vertically is arranged between the condenser of safety island, and support level is arranged on pillar.
Deflector contacts with support when primary importance.
When deflector leaves primary importance towards steam turbine building one side.
Description of drawings
Fig. 1 is the overall schematic of the described Air-Cooling Island water conservancy diversion of the application defroster.
Fig. 2 is the schematic internal view of the described Air-Cooling Island water conservancy diversion of the application defroster.
Fig. 3 is the side schematic view of the described Air-Cooling Island water conservancy diversion of the application defroster.
The specific embodiment
As Figure 1-3, exhaust steam enters steam distributing pipe 5 after the steam turbine internal insulation expands acting, then is dispensed in heat radiator fin tube bank 6.Cold surrounding air is restrained 6 belows from heat radiator fin and is sucked, and flows through from the gap of tube bank, discharges from the top after the latent heat of exhaust steam in absorption tube.Exhaust steam collects in condensate water header 7 through the condensate water of condensation after heat exchange.
The place is equipped with deflector 3 and overhead gage 4 at the safety island top exit, and overhead gage 4 is horizontally disposed with, and is installed with many group traction electric machines 1 on overhead gage.Deflector 3 is provided with bearing, and driving chain 2 one ends are driven by traction electric machine 1, and the other end is fixed on the bearing of deflector 3.Control traction electric machine 1 drive driving chain 2 deflector 3 is rotated around overhead gage 4, and the angle between deflector 3 and horizontal plane is adjustable, can realize the adjusting of Air-Cooling Island outlet circulation area.Deflector 3 is closed described outlet when primary importance, open described outlet when leaving primary importance.This mode of operation response is fast, and thermal-insulating sealing is good.
Be installed with limiting plate 10 between deflector 3 and overhead gage 4, make 0 °≤θ of 4 angles of deflector 3 and overhead gage≤80 °.Deflector 3 angle of 4 of deflector 3 and overhead gages when primary importance is 0 degree.
Support 8 and pillar 9 are installed between condenser 5, and pillar 9 vertically is arranged between the condenser 5 of safety island, and support 8 is horizontally set on pillar 9,, contacts with support 8 during in primary importance when deflector 3.8 pairs of deflectors 3 of support this moment play a supportive role.
For avoiding condenser to freeze, when environment temperature reduces or unit exhaust steam amount when reducing, start traction electric machine 1 and rotate and unclamp driving chain 2, deflector 3 is fallen, angle theta constantly reduces, and closes outlet when arriving primary importance until deflector 3 puts down fully.
When environment temperature rising or the increase of unit exhaust steam amount, start traction electric machine 1 and rotate driving chain 2, make deflector 3 increase, angle theta constantly increases until maximum angular 80 is spent.The air of the device that is condensed heating will continue to rise along deflector 3 after the Air-Cooling Island outlet is flowed out, and prevent hot air reflux, to improve the Air-cooled Unit heat exchange efficiency.
For ensureing that deflector 3 suppresses the effect of hot air reflux, should be towards steam turbine building one side when leaving primary importance after deflector 3 rises.
