Abstract
The invention discloses a fin type cooling tower airduct which comprises a cylindrical airduct body, wherein a plurality of heat collecting fins are uniformly arranged on the outer wall of the cylindrical airduct body; the cylindrical airduct body is filled with a heat collecting net. Through the adoption of the fin type cooling tower airduct, in the high-temperature environment, hot and humid air ventilation resistance and back-mixing phenomena can be reduced; in the low-temperature environment, the wet vapor condensation is accelerated, the evaporated water amount is reduced and the water mist at the outlet of the cooling tower is eliminated or reduced.
Description
Technical field
The present invention relates generally to field of heating ventilation air conditioning, relates in particular to a kind of finned cooling tower air duct.
Background technology
Cooling tower is the important component part of heating ventilation air-conditioning system, and its effect is that the recirculated water that carries waste heat is carried out to heat exchange at Ta Nei and air, and the heat of water is transferred to air and spills into atmosphere, and recirculated water is lowered the temperature.The quality of cooling tower runnability directly affects the effect of air-conditioning system cooling and warming.
In cooling tower, recirculated water and air carry out can producing damp-heat air from cooling tower outlet discharge after exchange heat, if the damp-heat air in the exit of cooling tower can not obtain effective lifting, affect the diffusion of damp hot discharge air, cause damp and hot air-flow back mixing, reduce the performance of cooling tower.So be back in cooling tower in order to reduce damp-heat air, common way is that air duct is installed in cooling tower exit, its Main Function is to create good air force condition, reduces flowing resistance, and the damp-heat air of discharging cooling tower is sent to high-altitude and reduces damp-heat air backflow.
Although cooling tower has been installed after air duct, can reduce damp-heat air and reflux, it can not solve two subject matters: 1, cooling tower has been installed after air duct, has increased the mobile resistance of damp-heat air, thereby has increased fan operation cost; 2, cooling tower has been installed after air duct, can not reduce the environment temperature white mist that damp-heat air forms when lower and produce.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide one can in hot environment, reduce damp-heat air flowing resistance and air-teturning mixed phenomenon, can in low temperature environment, accelerate the finned cooling tower air duct that damp steam condenses, reduces evaporated water, also eliminates or reduce cooling tower outlet water smoke.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of finned cooling tower air duct, comprises cylindrical tube, has been evenly arranged multiple thermal-arrest fins on the outer wall of described cylindrical tube, is filled with thermal-arrest net in described cylindrical tube.
Further improvement as technique scheme:
Described thermal-arrest fin is the rectangle plain fin axially arranging along cylindrical tube, and multiple thermal-arrest fins are circumferentially uniformly distributed along cylindrical tube.
Described thermal-arrest fin is the annular flat straight fins circumferentially arranging along cylindrical tube, and multiple thermal-arrest fins are axially uniformly distributed along cylindrical tube.
Described thermal-arrest net arranges along cylindrical tube radial section.
Described thermal-arrest net is provided with multilayer, and multilayer thermal-arrest net is axially uniformly distributed along cylindrical tube.
Described cylindrical tube is metal cylinder, and described thermal-arrest fin is metal fin, and described thermal-arrest net is wire netting.
Compared with prior art, the invention has the advantages that:
Finned cooling tower air duct of the present invention is similar to a heat exchanger, in temperature higher summer, solar irradiation is mapped on the thermal-arrest fin of finned cooling tower air duct, thermal-arrest fin and cylindrical tube temperature are raise, then heat is passed to Hot wet air heating by thermal-arrest net in air duct, Hot wet air heating temperature raise and form larger buoyancy lift, discharging for damp-heat air the good air force condition of creating, having reduced flowing resistance and the air-teturning mixed phenomenon of damp-heat air; In temperature lower winter, damp-heat air in cylindrical tube passes to surrounding environment cold air by cylindrical tube and thermal-arrest fin heat, accelerated damp steam in damp-heat air condenses and comes back to cooling tower in cylindrical tube, reduce evaporated water and economize on water, can eliminate or reduce cooling tower outlet water smoke, be conducive to environmental protection simultaneously.
