Description
Technical field
The invention belongs to cooling device technical field, is related to one kind and is applied to thermal power plant, nuclear power plant and large-size chemical
The controllable air inlet system of large-scale wet-type cooling tower, in particular to one kind that enterprise uses are used for large-scale wet-type centre of cooling column region
Artificially or intake is automatically controlled, the system equipment of efficiency of cooling tower can be effectively improved.
Background technology
Large-scale wet-type cooling tower is mainly used in the enterprises such as thermal power plant, nuclear power plant and large-size chemical, is therrmodynamic system cold end
Important equipment, economy that its operating efficiency produces to enterprise, security play the role of and its important.It is limited to cooling tower in itself
The reason for structure, wherein the heart have an efficiency bad or failure region, reduce or eliminate this region can be obviously improved it is cold
But tower cooler efficiency.Technology used by for this problem, such as wind-guiding Manifold technology, layering air intake technology etc. can be solved partly
Above mentioned problem, but still have weak point：Such as passive air intake, it can not regulate and control on request；Take cooling surface of the rain belt to water
Product, reduce the cooling effect of cooling tower；Stratified charge technology requires higher in terms of mounting technique and cost.
From the point of view of the development of large-scale wet-type cooling tower, its diameter is increasing, the increase of bad or failure region；For hair
For power plant, load variations amplitude and frequency ratio are obvious in the past much bigger, and the change of such cooling tower operating mode is increasingly complex,
Monitoring and evaluation in actual motion to cooling tower cooling effectiveness lack method；Except controlling quantity of circulating water, without other effective
Method regulates and controls efficiency of cooling tower.The present invention can will accurately control the cold blast rate into centre of cooling column region, eliminate cooling
The cooling failure at tower center, inactive area, increase regulation and control, the effective means of monitoring efficiency of cooling tower.
The operating condition of large-scale wet-type cooling tower is sufficiently complex, is influenceed by factors, such as atmospheric pressure, temperature
Degree, humidity, wind direction, wind speed, quantity of circulating water, water quality in cooling tower, unit load and cooling tower inwardly projecting orifice, filler etc.；It is
The mass-and heat-transfer process of one Three-Dimensional Dynamic.
The content of the invention
To solve the deficiencies in the prior art, the present invention provides one kind and accurately controls cold air by cooling tower operating efficiency
Into its central area, its center cooling failure, decreasing effect region are eliminated, it is accurate to control cooling tower leaving water temperature, improve cooling tower
The controllable air inlet system of cooling tower of efficiency.
Technical method is used by the present invention solves its technical problem：In the bottom of cold tower, including rain belt, pond, water
More than one guide duct is installed to central area under pond, when guide duct is under pond and pond the outlet emersion of guide duct arrive
On the water surface of pond, and there is baffle plate to prevent rainwater from entering guide duct, the other end of guide duct is outside cooling tower rain belt, usually in water
The outside in pond.
More than one blower fan is connected with guide duct outer end, blower fan can be that blade is adjustable or rotating speed is adjustable.
The control of blower fan can be artificial or frequency converter or PLC, and it is all negative according to environmental factor or heat to control anyway
Operating mode in lotus working conditions change or cooling tower：Such as temperature, humidity measuring point, the temperature of extraneous air, humidity, wind speed in cooling tower
Deng by the data transfer that measuring cell measures to frequency converter or PLC, computer by way of data wire or wireless connection
Blower fan is controlled Deng controller, the purpose is to change the cold blast rate entered inside cooling tower, eliminates the cooling of centre of cooling column region
Failure, dead space.
Angle of fan leaves increase or rotating speed increase when dead space increases, until disappearing；At a temperature of central area
Angle of fan leaves changes when dropping to cooling tower outlet temperature or cooling tower temperature field mean temperature or rotating speed reduces, until blower fan
It is out of service.
The connection of blower fan and guide duct can be fixed or movable, to avoid blower fan from influenceing cooling tower
Air intake, it can be placed on below pool edge height when not running.
The size of guide duct, length, material, structure, shape etc. are not limited.
The beneficial effects of the invention are as follows：Solve the existing cooling decreasing effect in centre of cooling column region or inactive area cooling effect
Fruit is undesirable, and its air intake is passive, and change of temperature field loses monitoring；, can be in monitoring centre of cooling column region after the present invention is implemented
In the case of change of temperature field, it is accurately controlled into air quantity, eliminates the harmful effect in the region, efficiency of cooling tower is controlled always
System is in optimum level.Efficiency of cooling tower improves to be obviously improved to the economy and security of power plant and chemical enterprise.
