Abstract
The utility model provides a reverse -flow mechanical draft cooling tower, belongs to heat exchange technical field for solve the easy problem that runs off of traditional cooling tower when operation medium cooling water, its technical scheme is, it includes tower body, cooling blower, spray set and pond, tower body side wall's middle part is equipped with the air intake, and the top is equipped with the air outlet, cooling blower installs on the air outlet of tower body, spray set installs in the inside top of tower body, the pond sets up in the lower part of tower body, improves the back, along being equipped with the water guiding board to tower body inside below slope on the tower body air intake. The utility model discloses utilization setting water guiding board on edge on the tower body air intake prevents that the medium cooling water from urine appearing at the whereabouts in -process and following and suave phenomenon, has effectively reduced the loss of medium cooling water, has avoided the waste of water resource. This cooling tower is energy -conserving, environmental protection effect is showing, has reduced the moisturizing cost of enterprise.
Description
Technical field
The utility model relates to a kind of mechanical-draft cooling tower that prevents medium cooling water outflow, belongs to technical field of heat exchange.
Background technology
Cooling tower is using water as circulating coolant, absorbs heat and heat is disposed to the equipment in atmosphere from a system. Conventional reverse-flow mechanical-draft cooling tower is generally made up of tower body, the cooling blower that is arranged on tower body top and spray equipment, the pond etc. that is arranged on the wind deflector on tower body intaking air at middle part mouth and is arranged on tower body bottom. In cooling tower running, the medium cooling water that has absorbed heat from spray equipment ejection from top to bottom freely falling body to pond, tower outer air is up in air inlet enters tower, and discharge from tower top under the promotion of cooling blower, medium cooling water in tower also fully contacts with air reverse flow, the medium cooling water falling also dispels the heat by the evaporation of self in carrying out heat exchange with air, finally reaches the object of cooling. In actual use procedure, finding, there is following shortcoming in this traditional cooling tower:
1, the outside that medium cooling water can be along the planar flow at air inlet top to cooling tower in the time that Ta Bi flows down to air inlet, this phenomenon is commonly called as urine edge. Form urine after phenomenon, part medium cooling water cannot flow to pond, causes the loss of cooling water;
2, approach the vertical drop inside tower wall of vaporific medium cooling water and when the air inlet place, easily under the effect of extraneous ambient wind, waft in atmosphere, form the phenomenon of floating in the air, cause the loss of part cooling water;
3, four layers of wind deflector of the general layout of cooling tower intaking air at middle part mouth, the spacing between adjacent wind deflector is little, affects the ventilation cooling effect of medium cooling water.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of reverse-flow mechanical-draft cooling tower is provided, and to reduce the loss of medium cooling water, avoids the waste of water resource.
Problem described in the utility model realizes with following technical proposals:
A kind of reverse-flow mechanical-draft cooling tower, formation comprises tower body, cooling blower, spray equipment and pond, the middle part of described tower body sidewall is provided with air inlet, top is provided with air outlet, described cooling blower is arranged on the air outlet of tower body, and described spray equipment is arranged on tower body inner and upper, and described pond is arranged on the bottom of tower body, after improvement, be provided with to the weather board tilting below tower body inside on the upper edge of tower body air inlet.
Above-mentioned reverse-flow mechanical-draft cooling tower, is provided with packing layer in described tower body, and described packing layer is between spray equipment and the air inlet of tower body.
Above-mentioned reverse-flow mechanical-draft cooling tower, the width of described weather board is 0.1-1 meter, the angle of weather board and horizontal plane is 45 °-85 °.
Above-mentioned reverse-flow mechanical-draft cooling tower, the air inlet of described tower body is provided with wind deflector, and described wind deflector arranges two-layer, and every layer of wind deflector all becomes 30-60 ° of angle with horizontal plane.
The weather board that the utility model utilization is arranged on edge on tower body air inlet prevents that urine edge and free-and-easy phenomenon from appearring in medium cooling water in dropping process, has effectively reduced the loss of medium cooling water, has avoided the waste of water resource. In process of production, medium cooling water needs dosing processing, in stopping urine edge, the mistake of free-and-easy phenomenon minimizing current, has reduced the reagent consumption of cooling water, has stopped because of environment and atmosphere pollution around the free-and-easy cooling tower bringing simultaneously. This cooling tower energy-saving and environmental protection effect is remarkable, has reduced the moisturizing cost of enterprise.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is cutaway view of the present utility model (arrow in figure represents airflow direction).
In figure, mark is as follows: 1, cooling blower, 2, spray equipment, 3, packing layer, 4, tower body, 5, weather board, 6, wind deflector, 7, pond.
Detailed description of the invention
Referring to Fig. 1, the utility model mainly comprises cooling blower 1, spray equipment 2, packing layer 3, tower body 4, weather board 5, wind deflector 6 and pond 7.
Weather board 5 both can play guide functions to the medium cooling water flowing down along tower body inwall, prevented urine along phenomenon, and the cooling water that can cause to fall and break again, away from air inlet, avoids occurring free-and-easy phenomenon. The width of weather board 5 is 0.1-1 meter, becomes 5-45 ° (and angle 45-85 °) between horizontal plane with vertical tower wall. For circular cooling tower, multiple weather boards 5 connect into an annular entirety, and for the cooling tower of rectangle, weather board 5, along the elongated layout of length direction of cooling tower, makes cooling tower both sides form elongated weather board.
Wind deflector 6 is arranged on the concrete post of weather board 5 belows, 7 tops, pond, is evenly arranged. The utility model changes the wind deflector at traditional cooling tower middle part into 2 layers by 4 layers, strengthens cross-ventilation, has improved ventilation cooling effect.
Operation principle of the present utility model: air enters in tower from the air inlet of tower body bottom under the driving of cooling blower, then through packing layer, discharges from the air outlet of tower body through cooling blower. After being sprayed by spray equipment, drops on packing layer the medium cooling water that has absorbed heat, packing layer is porous material, for increasing the heat exchange area of cooling water, cooling water fully contacts with the air-flow rising in packing layer, carry out heat exchange, then fall into pond, in dropping process, further carry out heat exchange with the air-flow rising. When the cooling water of the cooling water flowing down along tower body inwall and close tower body inwall drops to air inlet, can under the guiding of weather board, flow to tower body middle part, prevent urine edge and free-and-easy phenomenon. Wind deflector both can make airflow smooth and enter tower body inside, can make again to float in the air to flow into pond to its surperficial cooling water, avoided the loss of cooling water.
