Abstract
The invention discloses an air draft barrel of a cooling tower. The air draft barrel of the cooling tower comprises a plurality of air-draft-barrel middle sections and a plurality of air-draft-barrel corners, wherein the air-draft-barrel middle sections are connected with one another through the air-draft-barrel corners to form an air-draft-barrel body with an inner cavity. The top end of the air-draft-barrel body is an air outlet, the bottom end of the air-draft-barrel body is an air draft port, and the inner diameters of the inner cavity of the air-draft-barrel body are gradually decreased from the top end to the bottom end and then gradually increased. Middle-section air draft areas and barrel corner air draft areas are respectively formed between the top ends and the bottom ends of the air-draft-barrel middle sections and the air-draft-barrel corners, and the middle-section air draft areas are communicated with the barrel corner air draft areas. The air draft barrel of the cooling tower is simple in structure, low in noise, low in maintenance cost, high in air draft efficiency, capable of improving heat exchange performance of the cooling tower, high in safety performance, and good in energy-saving effect.
Description
Technical field
The present invention relates to a kind of cooling device, relate in particular to a kind of cooling tower and pull out air duct.
Background technology
Present both at home and abroad circulating water cooling tower equipment is to drive air motion with blower fan as the air power source of cooling tower always, makes outside air and carries out heat exchange through the recirculated cooling water in the tower, to reach the purpose that reduces cooling water.The air duct of tradition mechanical ventilation type cooling tower is circular; under blower fan rotates from extraneous suction air; the hot water that flows in the inner-tower filling material carries out heat exchange with air from extraneous suction; will have like this that the actuating unit noise is big, the maintenance cost height of actuating unit, defective such as electric power resource consumption is big and security performance is low, do not satisfy people to environmental protection, economize on resources, improve the quality of living and the requirement of security.In order to overcome the defective of traditional mechanical ventilation type cooling tower, use no blower fan not have the motor cooling tower, can produce new problem so again, such as because this kind cooling tower cat head does not have air duct, extraneous air inlet is few, causes heat exchange performance low.
Summary of the invention
The technical problem to be solved in the present invention is, above-mentioned defectives such as the maintenance cost height of, actuating unit big at the actuating unit noise of circulating water cooling tower in the prior art, electric power resource consumption is big, security performance is low and heat exchange performance is low, provide a kind of simple in structure, noise is little, the maintenance cost is low, pull out wind efficient height, the heat exchange performance that can improve cooling tower, security performance is high and energy-conservation cooling tower pulls out air duct.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cooling tower pulls out air duct, comprise a plurality ofly pulling out the air duct stage casing and a plurality ofly pulling out the air duct angle, and pull out between the air duct stage casing by pull out the air duct angle connect and form have a hollow cavity pull out the air duct body; Pulling out air duct body top is air outlet, and its bottom is air-vent, and the internal diameter of hollow cavity that pulls out the air duct body diminishes earlier from the top to the bottom gradually, becomes big more gradually; Pull out the air duct stage casing and pull out the top at air duct angle and the bottom between be respectively equipped with that the wind district is pulled out in the stage casing and the wind district is pulled out at a tube angle, and the stage casing is pulled out the wind district and is pulled out the wind district with an angle and be communicated with.
In technical scheme of the present invention, described cooling tower pull out air duct comprise by a plurality of pull out the air duct stage casing and a plurality of pull out that the air duct angle is spliced to form pull out the air duct body, this pulls out the air duct body and has hollow cavity, and the internal diameter of this hollow cavity diminishes earlier from the top to the bottom gradually, become big more gradually, in addition, the middle part of pulling out the air duct body also is provided with by what the stage casing pulled out that wind district and tube angle pull out that the wind district forms and pulls out the wind district, so it is not only simple in structure that described cooling tower pulls out air duct, and such design improved the heat exchange performance of cooling tower greatly, increased the ability that guarantees the cooling tower safe operation, namely improved security performance, in addition, can also reduce the water pump water supply consumption, save the energy.
In technical scheme of the present invention, the internal diameter that pulls out the hollow cavity of air duct body diminishes earlier from the top to the bottom gradually, become big more gradually, the top of namely pulling out the air duct body is the diffusion type curve shape, its bottom is tapering type curve-like, and the air outlet of diffusion type curve shape has not only reduced the kinetic energy rejection of air outlet, and can also prevent from flowing back in the cooling tower from the damp-heat air that cooling tower is discharged, tapering type curvilinear air-vent can reduce the resistance of air-vent, makes air-vent more smooth and easy without hindrance; In addition, pulling out wind district and tube angle by the stage casing pulls out the wind district and is communicated with the wind district of pulling out constitute and has also increased the ability that sucks extraneous air-flow, also increased the intensity that described cooling tower pulls out air duct, what these had improved greatly all that described cooling tower pulls out air duct pulls out wind efficient, has also reduced the noise when cooling tower pulls out air duct work simultaneously.
In technical scheme of the present invention, the described air duct that pulls out is installed in the cooling tower cat head, need not to suck air by the rotation of blower fan from the external world, and the cooling tower that pulls out air duct with nothing is compared, cooling tower of the present invention relies on the throughput that air duct sucks from the external world of pulling out of its cat head to increase by 30%, so not only avoid producing noise, but also greatly reduce the maintenance cost of cooling tower.
As a kind of improvement to technical scheme of the present invention, pull out the air duct stage casing and be provided with vertical strengthening ribs and horizontal reinforcement.Pull out on the air duct stage casing vertical strengthening ribs and laterally reinforcement help to strengthen pulling out the intensity in air duct stage casing.
As a kind of improvement to technical scheme of the present invention, pull out the air duct angle and be provided with vertical strengthening ribs and horizontal reinforcement.Pull out the vertical strengthening ribs and the horizontal reinforcement that arrange on the air duct angle and improved the intensity of pulling out the air duct angle.
As a kind of improvement to technical scheme of the present invention, pulling out the air duct angle is the arc corner.
As a kind of improvement to technical scheme of the present invention, pull out the air duct stage casing and adopt fiberglass or polyvinyl chloride to make.
As a kind of improvement to technical scheme of the present invention, pull out the air duct angle and adopt fiberglass or polyvinyl chloride to make.
In addition, in the technical scheme of the present invention, all being not specifically noted all can be realized the technical program by adopting the routine techniques in this area.
Therefore, the invention has the beneficial effects as follows provides a kind of cooling tower to pull out air duct, and it is simple in structure that this cooling tower pulls out air duct, and noise is little, and the maintenance cost is low, pulls out wind efficient height, can also improve the heat exchange performance of cooling tower, security performance height, and good energy-conserving effect.
