Abstract
A natural-ventilation indirect air cooling tower bypass ventilating device is characterized in that a plurality of bypass ventilating openings are formed between the bottom of an air cooling tower air duct and the top of a heat sink, and an electric air door or an electric blind window with the opening degree adjustable is adopted for the bypass ventilating openings; when the environment temperature is very low in winter, and the outlet water temperature of the heat sink can not be maintained to be higher than the safety water temperature, the bypass ventilating openings are opened, cold air in the environment enters a tower, the air temperature in the tower is lowered, the draft force in the tower is reduced, the blind window pressure difference of an inlet of the heat sink is reduced, the ventilating amount of the heat sink is reduced, and the anti-freezing effect of the heat sink and the effect of reducing the temperature stress of the tower are achieved.
Description
Technical field
The utility model is mainly used in cold district gravity-flow ventilation indirect air cooling Tower System.
Background technology
That gravity-flow ventilation indirect dry cooling tower has is energy-conservation, noise reduction, be subject to the plurality of advantages such as large wind effect is little, stable, has the gesture of application in the rich coal of northern China water-deficient area.Its basic principle is the recirculated water utilizing in ambient, cool air cooling radiator, after cold air is heated to be hot-air, density reduces, and entering cooling tower inside, cooling tower inner air and outer air density contrast produces draft, forms gravity-flow ventilation indirect dry cooling tower and continues the power ventilating.Gravity-flow ventilation indirect dry cooling tower mainly faces two problems when northern China is applied: 1, the antifreeze problem of radiator tube bank.Because severe cold area winter environment temperature is low, need regulate and significantly reduce ventilation to control cold water temperature by radiator inlet louver, after air quantity reduces, air temperature rise significantly improves, cooling tower draft significantly improves thereupon, because shutter closed condition also can not seal completely, still have certain inleakage, thereby the draft meeting significantly increasing has weakened shutter regulating power.When ambient, cool air temperature is extremely low, radiator freeze injury risk will obviously improve.2, tower cylinder temperature stress problem.The inside and outside limit temperature difference of gravity-flow ventilation indirect dry cooling tower air duct appears at winter, and severe cold area indirect dry cooling tower in winter internal-external temperature difference is larger, has improved the limiting temperature stress of tower cylinder, has worsened tower cylinder stress condition, and then increases the quantities of air cooling tower air duct.
Utility model content
The purpose of this utility model is substantially not change under the prerequisite of original technology arrangement, by setting up by-pass ventilation mouth, while realizing winter operation to cooling tower supplements cold, reduce temperature and draft in tower, reduce radiator inlet louver external and internal pressure poor, and then realize and reducing by radiator ventilation, reduction freeze injury risk, reduction tower cylinder temperature stress object, realize the operation of gravity-flow ventilation indirect dry cooling tower Winter safety and reduce the targets such as cooling tower air duct initial cost.
For achieving the above object, the utility model provides a kind of gravity-flow ventilation indirect dry cooling tower by-pass ventilation device,
It is characterized in that: between air cooling tower air duct bottom and radiator top, establish some by-pass ventilation mouths, by-pass ventilation mouth adopts MOD or the electric-powered shutter of adjustable aperture, when winter environment temperature very low, radiator leaving water temperature cannot maintain safe water temperature when above, open by-pass ventilation mouth, ambient, cool air is entered in tower, reduce temperature in tower, reduce draft in tower, reduce radiator inlet louver pressure reduction, reduce the ventilation of radiator, reach the double effects of heat radiator anti-freezing and reduction tower cylinder temperature stress.
Relative conventional design scheme, good effect of the present utility model is:
1, winter can be by regulating by-pass ventilation mouth and radiator inlet louver aperture to jointly control the air quantity through radiator, make radiator ventilation obtain more effectively controlling, improve heat radiator anti-freezing level of control, reduce freeze injury risk, realize the operation of gravity-flow ventilation indirect dry cooling tower Winter safety and reduce the targets such as cooling tower air duct initial cost;
2, during winter operation, can reduce tower internal-external temperature difference, reduce tower cylinder limiting temperature stress.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
In figure: 1, radiator; 2, radiator inlet louver; 3, by-pass ventilation mouth; 4, air cooling tower air duct; 5, air cooling tower air duct pillar.
The specific embodiment
With reference to accompanying drawing 1, radiator 1 is arranged vertically in cooling tower air duct pillar 5 peripheries, between cooling tower air duct 4 bottoms and radiator 1 top, some by-pass ventilation mouths 3 is set.When indirect dry cooling tower moves the season beyond in the winter time, by-pass ventilation mouth 3 is in closed condition, and cold air all enters cooling tower inside through radiator.During winter operation, first by radiator inlet louver 2, regulate by the air quantity of radiator, controlled circulation water temperature is higher than safety value, when cold air temperature is extremely low, open by-pass ventilation mouth 3, cold air is directly entered in cooling tower by by-pass ventilation mouth 3, mix with the hot-air entering in tower by radiator 1, reduce the temperature of mixing air in tower, reduce draft in tower, and then realize and reduce cooling tower air duct 4 limiting temperature stress and the object that reduces radiator 1 ventilation, improve heat radiator anti-freezing level of control, improve gravity-flow ventilation indirect dry cooling tower in the adaptive capacity of severe cold area.
