Abstract
The utility model relates to a cooling tower, comprising a tower body and an air inlet device, wherein the bottom center of the tower body is provided with an air inlet, the air inlet device is arranged on the air inlet, the two sides of the air inlet device are provided with air outlet passages, and a baffle is arranged above the air outlet passages. The cooling tower has the beneficial effects that by adopting a bottom air inlet structure, the cooling tower overcomes the defects caused by the fact that the existing cooling tower adopts a side air inlet structure; the stability of air flows entering the tower is good, so that the influence of the wind force in the outside atmosphere on the cooling tower is avoided; air can enter the towerfrom the air inlet directly, so that the air inlet resistance is reduced, the air flowing is smooth, and the cooling efficiency is improved; and the distribution of the air flows in the tower tends to be uniform due to the design of the stepped air inlet device, so that the cooling efficiency is improved.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of cooling tower.
Background technology
At present, square counterflow cooling tower tower body commonly used is built on stilts to be installed on the ground strut, be provided with water-collecting tray in the tower body from lower to upper successively, packing layer, spray system and blower fan, air inlet is arranged on the bottom of tower body two sides, namely have the strip air inlet in the bottom of tower body two sides, it is excessive to prevent inner rainwater that each air inlet is equipped with the used in blinds that keeps off the rain, and air outlet is arranged on the top, use blower fan air inducing, upwards exhaust, the below of blower fan is provided with spray system, formed by inlet channel and spraying device, so that medium hot water to be cooled is equably to the packing area sprinkle, hot water flows downward in the packing area and fully contacts with flow air upwards and carries out the obversion heat exchange, contains hot water vapor and is taken away by air, hot water is cooled off, flow into the district of drenching with rain then, WATER AS FLOW MEDIUM is further cooled off, last WATER AS FLOW MEDIUM flows into water-collecting tray and discharges from outlet pipe.Airflow direction in the cooling tower is for flowing from the bottom up, be negative pressuren zone in the tower, air enters tower body from two side air inlet mouths through shutter, the uniformity of the big or small gentle distributions of air mass flow is the important indicator that is related to cooling effectiveness in the cooling tower, but there are following several problems in the structure of this side air inlet:
The one, air-flow skewness in the tower has reduced cooling effectiveness.Because be air intake from the side, air-flow mainly concentrates on the inlet side, namely near the tower body outer wall, is difficult for entering the middle part, the strongest near the air-flow of outer wall, more past central gas stream is more weak; On the other hand, above the blast (negative pressure) that produces of air-introduced machine also be strong outside and weak inside, the outer ring is the strongest, more past central pressure is more weak; Because of the restriction of blower fan structure, the tower center has a circle district to be calm nip again.Owing to exist above-mentioned several reasons to cause the interior air-flow skewness of tower body, consequently can not give full play to the cooling effectiveness of cooling tower.
The 2nd, the air intake resistance is big.Extraneous air must change two around shutter and enter in the tower with bending, get on, get off, and the air intake resistance increases, and air quantity is reduced, and this also directly influences cooling effectiveness.
The 3rd, be subjected to the interference of atmospheric environment easily, job insecurity.Tower body pressure at both sides imbalance under the effect of atmosphere wind-force, it is low that air pressure has height to have, and makes air quantity, the air-flow skewness of both sides in the tower body, and when wind-force is serious on one side even can come out from the another side of entering, the reduction cooling effectiveness also influences the stability of cooling tower work.
The 4th, area occupied is bigger.For keeping the unobstructed air inlet of air intake outside to need to leave certain space, in the certain distance scope, can not there be obstacle, this is with regard to more ground area occupied and space.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned employing side air inlet structure is brought, and a kind of cooling tower that adopts novel air inlet structure is provided.
The technical solution of the utility model is: a kind of cooling tower, comprise tower body and air-intake device, and tower body bottom centre is provided with air inlet, and air-intake device is installed on the air inlet, and described air-intake device both sides are provided with the exhaust passage, and the top, exhaust passage is provided with weather shield.
As preferably, described air inlet is rectangle, square, circle or cross.For jumbo cooling tower, can adopt the cross air-intake device, intake is increased, air-flow distributes and also more becomes evenly, and the bottom water-collecting tray of cross air-intake device will be divided into four parts and make air intake passage to reserve the cross space.
As preferably, the weather shield on the exhaust passage is downward-sloping, is convenient to rainwater and enters water-collecting tray.
As preferably, described air-intake device is step structure, and each ladder both sides is equipped with the exhaust passage, and weather shield is all established in each top, exhaust passage, and this structure can make air-flow be more evenly distributed in tower body.
As preferably, the material of described weather shield is fiberglass.
The beneficial effects of the utility model: adopt the cooling tower of middle part air intake structure can not suffer the intrusion of atmosphere wind-force and rainwater, advance the good stability of tower air-flow, can avoid outside atmosphere wind-force to the influence of cooling tower, improve its job stability; Air inlet directly air intake does not have shutter, and the air intake resistance reduces, and makes air-flow unobstructed, improves cooling effectiveness; The design of staged air-intake device will make that air-flow distributes trend evenly in the tower, can improve cooling effectiveness, enter because air-flow is stepped ventilation road segmentation from the centre, can evenly distribute from the near to the remote; Air inlet is arranged on the tower body bottom, reduce the hold facility area, air-flow enters from the cooling tower bottom, only otherwise the overhead space between the tower body bottom shore is stopped, the tower peripheral space is not strict with, reduced area occupied and space, if many cooling towers are arranged together, then can any combination discharging.
