Technical field
The utility model proposes the cooling column shutter air intake adjusting device of power-plant cooling water field application.
Background technology
Cooling column is the structures that power plant is used for cold water, and general height is depending on the unit size of power plant, is electricity
Factory's using water wisely, a kind of structures of cycling use of water.The operation principle of cooling column:Using blow into come wind with spilling from above
Water formed convection current, thermal source is drained, a part of water evaporates in convection current, has taken away corresponding evaporation latent heat.So as to reduce water
Temperature.
It is all to use the gravity-flow ventilation type of cooling that wet type cooling unit is most of, improves cooling tower performance, true to improving condenser
The empty and most important data of unit efficiency shows, to 300MW units, outlet water temperature degree is reduced, and unit vacuum can be made to improve 400Pa
~ 500Pa, generating standard coal consumption decline 1.0g/ (kW.h) ~ 1.5 g/ (kW.h).In addition, many research shows:Beam wind
Very big on cooling tower thermal performance influence, appropriate measure can reduce the influence of beam wind.It is cold with certain 300MW unit gravity-flow ventilation
But exemplified by tower, influence of the horizontal wind speed to cooling tower thermal performance is simulated and analyzes, and according to different vesicularity walls to going out tower
The influence of water temperature, propose to install improved cooling column shutter air intake adjusting device additional in rain belt.
The abat-vent now used be mostly fixed plank or iron sheet, it is necessary to all be hung up before the winter is entered, summer is complete again
Remove in portion.The demolition, installation of deep bead are entirely manually to complete, and workload is big, both unsightly or dangerous.One tears a dress process open
In material is lost, and labour cost is high.It is costly that such construction is all carried out every year.
Although fixed plank and iron sheet can play gear wind action, it is unable to the random groups method of operation and is adjusted
Section, when unit load increases, temperature raises after recirculated water heat exchange, it is impossible to adjusts water temperature with load variations.And then influence condenser
Vacuum and unit efficiency.
Utility model content
The problem of existing for prior art, the utility model proposes cooling column shutter air intake adjusting device.The dress
The purpose put is to provide a kind of whatsoever season, no matter night on daytime can realize accurate control in time to deep bead.Solve
The technical problem of cooling column temperature adjustment.
Scheme is used by the utility model solves technical problem：
Vertical blinds is housed in the bottom of cooling column periphery, it is horizontal on the cooling column on the upside of vertical blinds to have horizontal blinds.
Vertical blinds bottom is provided with chassis, and top is provided with annulus；
Vertical blinds side is connected with vertical blinds driver equipped with eccentric rotating shaft in rotating shaft；
U-board is provided between one section of horizontal blinds, U-board is equipped with horizontal blinds by bracing piece；
Pulling rope is connected between horizontal blinds in bracing piece, pulling rope top is connected with drawstring driver.
Horizontal blinds and vertical blinds set by cooling column periphery are driven by vertical blinds driver and drawstring driver respectively, are led to
Cross controller and the regulation that energy carries out angle is provided, realize insulation or radiating.
Horizontal blinds and vertical blinds are referred to as deep bead.
Good effect, the utility model can automatically adjust the angle of vertical blinds and horizontal blinds, therefore can protect in the winter time
Temperature, summer radiating, ensure that cooling column within suitable operating temperature, has the advantages of environmental protection and energy saving, easy to control.It is suitable to make
Used for the device of cooling column temperature adjustment.

Embodiment
According to the figure, vertical blinds 3 is housed in the bottom of the periphery of cooling column 0, it is horizontal on the cooling column on the upside of vertical blinds to have
Horizontal blinds 5.
Vertical blinds bottom is provided with chassis 1, and top is provided with annulus 2；
Vertical blinds side is connected with vertical blinds driver 3.2 equipped with eccentric rotating shaft 3.1 in rotating shaft；
U-board 4 is provided between one section of horizontal blinds, U-board is equipped with horizontal blinds by bracing piece 6；
Pulling rope 8 is connected between horizontal blinds in bracing piece, pulling rope top is connected with drawstring driver 7.
Horizontal blinds and vertical blinds set by cooling column periphery are driven by vertical blinds driver and drawstring driver respectively, are led to
Cross controller and the regulation that energy carries out angle is provided, realize insulation or radiating.
Horizontal blinds and vertical blinds are referred to as deep bead.
Technical principle：
Shutter air intake adjusting device, using rotary shield, gear is automatically adjusted according to the change of wind direction, wind speed and water temperature
Plate angle degree.
Operator scheme is from motion tracking regulation, on the spot distant place motorized adjustment, manual regulative mode.According to weather conditions and machine
Group situation, the structure of cooling tower air intake adjusting device is targetedly designed, be totally divided into 12 directions, each direction is one
Unit, each two groups of unit, every group can individually control.
（1）Horizontal blinds and vertical blinds selection：High-quality sheet iron is selected, centre is provided with reinforcement, and both ends are by aluminum alloy materials
Do end cap, the interspersed steel shaft in centre.In light weight, intensity is high.
（2）The selection of ceiling floor：
1. ceiling floor uses glass steel sheet, thickness is the ㎜ of δ=4, and there is the framework that steel I-beam and channel, angle steel make lower section
Support to strengthen its rigidity, it is ensured that it can bear tower top winter snow cover, hang the weight of ice.
