Abstract
An eddy flow wet type reverse flow cooling tower mainly includes a reinforced concrete casing tower cylinder, wherein a water collector, a water distribution device, a water drenching filler, and a water collecting pond are arranged in the tower cylinder; and an eddy flow facility is arranged on the inner wall and the bottom of the tower cylinder, and includes eddy flow ribs, flow guide plates, flow guide blades and flow guide pillars. The eddy flow wet type reverse flow cooling tower has the advantages that the eddy flow facility generates the upward eddy flow airflow, so as to help to remove the water content in the discharged airflow in the tower, enable water drops in the airflow in the tower to fall into the water collecting pond, and saving the circulating water of the cooling tower; meanwhile, the eddy flow enables the airflow discharged out of the tower top to go higher for diffusion again, thereby reducing the harmful effect on neighboring environment; and the eddy flow ribs can further enhance the strength of the tower cylinder of the cooling tower.
Description
Technical field: the present invention relates to a kind of circulation cooling infrastructure, is a kind ofly used heat to be exchanged the cooling tower that spills into atmosphere to air again, particularly a kind of rotational flow wet-type countercurrent cooling tower.
Background technology: cooling tower is a kind of circulation cooling infrastructure, and its will carry under one's arms cooling water of used heat exchanges at Ta Nei and air; Make used heat be transferred to air and spill into atmosphere again, it is widely used in many departments of national economy, as: electric power, oil, iron and steel, chemical industry and textile industry.Existing wet-type countercurrent cooling tower adopts the gravity-flow ventilation structure more, referring to accompanying drawing 1,2, it consists predominantly of a reinforced concrete shell tower tube 1 that is hyperbolic-type, herringbone column 6 is arranged around at the bottom of the tower tube, tower tube 1 inner wall smooth, no adjunct, tower tube 1 inner bottom part has water collection device 2, water dispensing apparatus 3, packing 4, collecting-tank 5.If adopt the cooling tower of force ventilation, except that the said structure part, also include a mechanical ventilator.In cooling stack, fresh air air inlet at the bottom of the tower enters in the tower, heat absorption back temperature raises, density reduces, form density contrast with tower outer air density, thereby in tower, produce the draft of above the tower tube, moving, mechanical-draft cooling tower then is to extract out outside the tower from bottom to top air in tower by the blower fan at tower tube top, the wet-type countercurrent cooling tower of gravity-flow ventilation or force ventilation no matter, the motion of air in tower is straight-flow air from bottom to top basically, the defective of prior art wet-type countercurrent cooling tower is: the moisture content that contains in the direct current wind ascending air that produces in the tower tube is more relatively, and it is excessive to cause cooling-tower circulating water to consume; In addition, cat head is discharged the exhaust insufficient height height of air-flow, easily the work area surrounding environment is produced harmful effect.
Summary of the invention:
The objective of the invention is to overcome the defective of prior art wet-type countercurrent cooling tower, design a kind of economized cycle water consumption, and reduce dysgenic cooling tower surrounding environment.
Technical scheme of the present invention is a kind of rotational flow wet-type countercurrent cooling tower, two kinds of ventilation patterns of gravity-flow ventilation and mechanical ventilation type are arranged, the natural ventication rotational flow wet-type countercurrent cooling tower mainly comprises hyperbolic-type reinforced concrete shell tower tube, tower tube inner bottom part has water collection device, water dispensing apparatus, packing, collecting-tank, the eddy flow facility is equipped with in tower tube inwall and bottom, and the eddy flow facility includes eddy flow rib, deflector, guide vane, diversion column.Force ventilation type rotational flow wet-type countercurrent cooling tower structure is except that above-mentioned part, and mechanical ventilator also is equipped with at tower tube top.
The eddy flow rib that is the rising of helical type is from bottom to top arranged at tower tube inwall.
Tower tube bottom water collection device top is provided with some deflectors, evenly distributes in the form of a ring around the cooling tower center, is spaced from each other, and every deflector departs from the β angle with this distributed points tangential direction of distribution rings separately, to the centroclinal setting of cooling tower.
Tower tube bottom water collection device top is provided with some guide vanes by radial distribution around the mind-set in the tower tube, and guide vane is paddle-like in the shape of a spiral.
Tower tube center is provided with the diversion column of through top of tower above water collection device, be wound with some spiralling guide vanes on the diversion column from bottom to top.
The advantage of rotational flow wet-type countercurrent cooling tower of the present invention is: because the eddy flow facility is arranged, can in tower, produce spiralling rotational flow air stream, compare with the distinguished and admirable wet-type countercurrent cooling tower of existing direct current, its advantage is that the moisture content that contains in the air-flow of cat head discharge is less, thereby saved the cool cycles water, because the vortex gas-flow of discharging leaves the higher height of cat head rising, just be diffused in the atmosphere simultaneously, thereby less to the harmful effect of surrounding environment, and the eddy flow rib also can be strengthened tower tube intensity.

The specific embodiment:
The present invention further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:
A kind of rotational flow wet-type countercurrent cooling tower, mainly constitute by tower tube, water collection device, water dispensing apparatus, packing, collecting-tank and eddy flow facility, the eddy flow facility comprises eddy flow rib, deflector, guide vane, diversion column, but various parallel works matched combined.Rotational flow wet-type countercurrent cooling tower ventilation pattern has gravity-flow ventilation and force ventilation, and force ventilation type rotational flow wet-type countercurrent cooling tower also comprises mechanical ventilator except that the said structure part.Its specific embodiment division is as follows.
Embodiment 1, a kind of rotational flow wet-type countercurrent cooling tower, it is natural ventication, referring to accompanying drawing 3,4, hyperbolic-type reinforced concrete tower tube 1 bottom is supported with herringbone column 6, there is water collection device 2 tower tube 1 inherent herringbone column 6 tops, water dispensing apparatus 3, packing 4, there is water collector 5 tower tube 1 bottom herringbone column below, the eddy flow facility is housed in the tower tube 1, it is one group of eddy flow rib 7, and eddy flow rib 7 is contained on tower tube 1 inwall, from tower tube 1 bottom herringbone column 6 tops, rise along tower tube 1 spiral inner wall, until tower tube 1 top exit.Shape city guiding gutter between the rib, ascending air flows after causing eddy flow near tower tube 1 wall, drives air formation rising eddy flow wind in the tower tube 1 effectively.
No matter be natural ventication or force ventilation type rotational flow wet-type countercurrent cooling tower, because the effect of eddy flow facility all can produce the tornado flow that rises in the tower tube, cooling tower is in service, hot water evenly sprays on the packing through water dispensing apparatus, behind packing, fall into collecting-tank, air mainly fully contacts heat-shift in the packing district with hot water, the heat of water is passed to air, in the tower tube, upwards move, enter atmosphere from top of tower at last, contain many water droplets in the ascending air stream, the present invention is owing to there is the eddy flow facility to produce the rising eddy flow, eddy flow can utilize on the one hand centrifugal force to get rid of water droplet in the air-flow, and it is recycling again to make it to fall into collecting-tank, thereby saves cycling use of water; The higher height of rising spread again after eddy flow can make air discharge cooling tower again on the other hand, thereby reduced the surrounding enviroment harmful effect; The eddy flow rib also has the effect of strengthening tower tube intensity simultaneously.
