Description
Technical field
The invention belongs to technical field of air conditioner refrigeration, and in particular to a kind of cooling tower water-distributing device and cooling tower.
Background technology
Cooling tower is the key equipment of technical field of air conditioner refrigeration, is mainly used in distributing the condensation of water cooled refrigeration unit
Heat, to ensure the normal operation of refrigeration unit.Due to the fluctuation of the change in season, and cooling load, cause refrigeration unit
It is the rated cooling capacity for deviateing equipment to contribute under the most of the time.To adapt to the change of unit semen donors, to save operation
Energy consumption, current refrigeration system takes water pump unit number control or the method for pump variable frequency control adjusts cooling current
Amount, so as to which the metered flow of cooling water flow and cooling tower can be caused inconsistent and be less than the metered flow of cooling tower.In addition,
During actual engineering practice, also usually there is cooling water flow because of the reason such as design or device configuration and be more than cooling tower
The situation of metered flow.The water-distributing device of traditional cooling tower is using simply open rectangle basin, and in the perforate of basin bottom
Mode, while injected current among basin using the form of water filling in single point set.When water shortage, it will occur liquid level without
Method is covered with whole basin, part water distributing pore it is anhydrous can cloth, cause partial filler region is anhydrous to flow through, void space gas flows through packing area
The serious conditions in domain.Therefore for traditional cooling tower, when flow is less than metered flow, it will cause cooling tower water distribution
Uniformity is deteriorated, and the efficiency of cooling tower is relevant with uniformity of water distribution, and water distribution is more uniform, and efficiency is higher, and vice versa.And when stream
When amount is more than metered flow, traditional cooling tower can then make water distribution membranization degree be deteriorated, and filler passage narrows, and circulation windage increases,
Air quantity diminishes, and this can similarly reduce the cooling effectiveness of cooling tower.In addition, traditional cooling tower water-distributing device there is also the change of basin bottom
Shape causes the water level of each water distributing pore deep mixed, and current are uneven, causes plus the current intense impact caused by water filling is concentrated
Liquid level crosses great fluctuation process, and this can also increase the unevenness of water distribution.
Because cooling tower is open equipment, its current directly contacts with air, will have in the process of running substantial amounts of
Dust is fallen among basin, and grows substantial amounts of microorganism mud, and using traditional water-distributing device, these impurity and mud all will
Packing area is all flowed into by the water distributing pore at basin bottom, and accumulated in because of packing area sluggish flow on filler, makes the flowing of filler
Resistance becomes big, and distribution performance deteriorates, and finally influences the overall cooling effectiveness of cooling tower.
The content of the invention
In order to eliminate traditional cooling tower in terms of distribution performance the defects of, the present invention propose a kind of cooling tower water-distributing device and
Cooling tower, improving the distribution performance of cooling tower, it is ensured that cooling tower can reach preferable cooling effectiveness in the case where becoming cooling water flow, and
Eliminate mud inside cooling water and flow through packing area, be attached on filler, the problem of influenceing hot and humid area and stream condition.
The technical proposal of the invention is realized in this way：A kind of cooling tower water-distributing device, including water distributing tray, the water distributing tray
Bottom is provided with some apopores, and some identical water distributors, the lower end of the water distributor and the water outlet are provided with the water distributing tray
Hole is connected, and the upper side of the water distributor is provided with inlet opening.The use of water distributor so that the water outlet of each apopore is uniform, from
And realize the uniformity of water distribution.And current are changed to the hole water outlet of water distributor lateral inflow by traditional bottom water outlet so that phase
The contamination precipitation of pass avoids the problem of mud impurity flows into packing area in water distribution tray bottom.
Further, in addition to cloth tank, the side of the cloth tank are provided with tapping hole, and the cloth tank passes through the tapping hole
Connected with the water distributing tray, the cloth tank is connected with water inlet pipe.The setting of cloth tank causes water inlet to first flow into cloth tank, then
The tapping hole through cloth tank flows into water distributing tray again, and such set causes waterflow stabilization to uniformly flow into water distributing tray.
Further, the water inlet pipe is connected with distributive pipe, and the distributive pipe includes closed interior distributive pipe and Wai Fenshui
Pipe, the interior distributive pipe connect with the water inlet pipe, and the upper wall of the interior distributive pipe is logical provided with what is connected with the outer distributive pipe
Hole, the lower wall of the outer distributive pipe are provided with the cloth tank inlet opening connected with the cloth tank.The setting of distributive pipe to intake
The cooling water of pipe is assigned in cloth tank uniformly and gentle, will not both cause longitudinal flow of the current in cloth tank, also not
The big ups and downs in cloth tank internal water face can be caused, so as to flow into the current of water distributing tray more stable and uniform.
Further, it is provided with overflow pipe in the cloth tank.When water is more than metered flow, unnecessary water is from overflow pipe
Overflow, be directly entered the drip tray of cooling tower, can so avoid excessive water from flowing into packing area, destroy filler current
Membranization characteristic, and increase the flowing resistance of packing area, cause air quantity to diminish, influence the cooling performance of cooling tower.
More preferably, the inlet opening is that ellipse is either vertical porous or is bar slit.
More preferably, the tapping hole is bar slit.
The cooling tower of the present invention includes two above-mentioned cooling tower water-distributing devices.
More preferably, it is communicated with pipe between the cloth tank of two cooling tower water-distributing devices.The cloth of the left and right sides can be ensured
The water of water installations evenly distributes.
Clever structure of the present invention, efficiently solve the uneven problem of traditional cooling tower water distribution.
