Abstract
The invention is a controllable air cooling system based on natural wind field, used for heat radiation by air cooling in heat power plant, able to prevent the interference of different air speeds and directions on the in-tower flow field, and because the air flow rotates in a worm air passage, which can deposit sand dust in the air, it can prevent the pollution of radiator, and there is a wind power generator set installed at the worm air inlet to adjust air inflow and generate electricity by being driven by air flow. After entering the air passage, the air can also adjust temperature: if temperature is over-low, able to heat to prevent cold injury to the radiator; and if temperature is overhigh, able to spray water in the air flow to reduce temperature, increase density and enhance cooling effect. After adjustment of flow and temperature and purification, the air passes through the radiator and implements cooling function and then enters in an air cooling tower through guide piece. It has an additional function of being able to act as a low-speed air tunnel to make aerodynamic experiment on relative objects.
Description
Technical field:
The present invention relates to a kind of adjustable natural wind field air cooling system,, build up spiral case and form air intake duct, prevent that the different directions air-flow is to the disturbance of air cooling tower flow field with the unified air mass flow that flows in the air cooling tower of controlling of wind energy conversion system.Give air heat with air heating pipe in case of necessity, prevent the too low freezing radiator of temperature,, reduce temperature and guarantee the air cooling effect with heat radiation sparge pipe water spray.Adjustable natural wind field air cooling system belongs to energy field thermal power generation specialty, the aerodynamics subject.
Background technology:
The air cooling technique that current thermal power plant and other steam power plant adopt is: natural air is under air cooling tower convection current suction, and by the shutter regulation and control, air is taken away the waste heat in the water by radiator, forms ascending air and keeps circulation.Owing to be subjected to season, weather conditions, air themperature and natural environment influences such as humidity height, wind-force size and wind direction variation, only adjust air mass flow with shutter, can not solve the problem that high temperature, microthermal climate and unit load size cause the operation difficulty, sometimes also because of shutter is not closed completely, freezing radiator.And, wasted the valuable wind resource that air cooling tower is in operation and forms in this way by air-flow.
Summary of the invention:
The objective of the invention is: solve under the natural environment, air is increased work efficiency to the influence of the normal operation of air cooling tower.
Below air cooling tower, around it, build spiral case, form air intake duct, prevent different wind speed and directions, air flow field disturbance in the tower.Under the guiding of air flue, form swirling eddy, commutate through flow deflector, become ascending air and can increase the air velocity degree like this, improve air cooling tower efficient by radiator.
Simultaneously, it is preceding under centrifugal action that air enters air cooling tower, and the heavy collection of the sand dust that is mingled with in air flue, is reduced the pollution to radiator, and the heavy sand and dust that collect also are convenient to cleaning.
At air inlet wind power generating set is installed, when needing to reduce air mass flow in the tower, the starting wind power generating set, effect is: the first, can reduce the air communication mistake, second, the airflow that can utilize air intake duct to form drives the wind-force unit generation, creates economic benefit.
In air intake duct wind-force unit back air heating pipe is installed, when intake air temperature was lower than zero degree, hot water heated the air that enters air flue through air heating pipe, prevents freezing radiator.
The heat radiation sparge pipe is installed in air intake duct heating tube back, when intake air temperature is too high, can be suitably sprayed water, the gasification of water reduces temperature, increases atmospheric density, strengthens radiating effect.
Structure of the present invention is:
At air inlet 1, wind wheel 12 and generator 8 constitute wind power generating set, are installed on the support 9, and air heating pipe 10 and heat radiation sparge pipe 11 are installed successively in its back.Spiral case 2 forms air intake duct 4 around air cooling tower 3 in the form of a ring, and air cooling tower support 5 is except supporting air cooling tower, or the UNICOM space of air intake duct and the interior ascending air of air cooling tower, at this position radiator 6 and flow deflector 7 is installed.
The advantage of controlled natural wind field air cooling system is:
1, the air intake duct that is formed by spiral case and air cooling tower can prevent that strong wind directly is blown into " draught " in the tower, destroys air flow field in the tower, influences the air cooling tower radiating effect.
2, air carries out temperature modulation before entering air cooling tower, and temperature is low excessively, can lead to hot water in air heating pipe, and air themperature is heated to above zero, reaches the purpose that prevents freezing radiator.When temperature is too high, by the heat radiation sparge pipe, to the air water spray of the air inlet of flowing through, in order to improve radiating effect.
3, can concentrate the air inflow of regulating air cooling tower, available powerful air-flow drives the wind power generating set generating in the levelling process.
4, air inlet can be done the low-speed wind tunnel use, and test Large-scale Wind Turbines performance perhaps to vehicles such as bridge, model of high-rise building and vehicle, boats and ships, is carried out the wind load test.
Description of drawings:
Fig. 1, interchangeable natural wind field air cooling system front view (broken section)
Fig. 2, adjustable natural wind field air cooling system vertical view
Fig. 3, air inlet cross-sectional view
Fig. 4, air inlet skiagraph
By Fig. 1,2,3,4, air inlet 1, spiral case 2, at air cooling tower 3, on every side structure Become volute air intake duct 4. When air passes radiator 6, under the effect of flow deflector 7, Change direction, passing air cooling tower support 5 increases flow velocity, rises at last the air cooling tower outlet Outward.
Form wind power generating set at air inlet 1 interior wind wheel 12 and generator 8, install On support 9. In the wind power generating set back, air heating pipe 10 heat radiation sprays are housed Water pipe 11.
Specific implementation method:
Adjustable natural wind field air cooling system basic function is: prevent the invasion and attack of strong wind to air flow field in the tower, regulate the flow of tower air, the tower air themperature is advanced in control.In this process, utilize powerful air-flow to drive wind turbine power generation.
Build up air cooling tower 3 and spiral case 2 by Fig. 1, constitute air intake duct 4.Air can only flow into from air inlet 1, prevents that strong wind and wind direction from changing the invasion and attack to air flow field in the tower.
The wind power generating set that startup is made up of wind wheel 12 and generator 8 drives the unit running by air-flow and reduces passing through of air-flow, and can generate electricity.
As: after generator 8 energisings, become 12 one-tenth air-introduced machines of motor drives wind wheel, can increase the into air mass flow of tower.
Advance the air cooling tower air themperature and cross when hanging down, air heating pipe 10 logical hot water raise the air themperature of passing through, and prevent freezing radiator.
When advancing the tower too high temperature of air, heat radiation sparge pipe 11 makes its atomizing reduce air themperature to the air-flow water spray, increases atmospheric density, the enhance heat effect.
