Abstract
A multilayer water distribution device of a counter-flow cooling tower comprises a vertically upward water inlet pipe and a water distribution pipeline, wherein the water inlet pipe is arranged in a tower body or outside the tower body, the water distribution pipeline is connected with the water inlet pipe and arranged above filler, the water distribution pipeline comprises at least two branch pipes and water distribution sprayers, the branch pipes are arranged on the water inlet pipe layer by layer at certain height intervals and can achieve uniform water distribution under different flows of the water inlet pipe, additionally pipeline water resistance is not increased, and accordingly the aims of selecting a low-lift water pump and reducing energy consumption of the water pump are achieved. The cooling tower can achieve uniform water distribution when the flow changes, and cooling efficiency of the cooling tower is improved. Meanwhile, due to the principle that towers are U-type pipelines connected with a main pipe, water distribution of a lower layer is made to be achieved first when the flow of each tower is small, and accordingly uniform water distribution between the towers is achieved and uniform water diversion and water distribution of a cooling tower group are achieved when the flow changes. The device is simple to manufacture and convenient to install, and operation cost is effectively reduced.
Description
Technical field
The invention belongs to counterflow cooling tower preparation field, relate in particular to counterflow cooling tower water distribution liquid distribution.
Background technology
The cooling water distribution manner of countercurrent tower on existing market, most design is to adopt inlet channel on average to configure, water-distribution nozzle is installed in pipeline below or square regulates shower nozzle, its drawback is the in the situation that of low discharge, water-distribution nozzle there are flowing out near water distribution pipe water inlet end, and far-end water outlet is seldom or there be not water ejection, cause the part film-cooled heat of cooling tower to utilize, affect cooling effect; And when large flow and oepration at full load, because it is changeless being arranged on the quantity of ducted water-distribution nozzle, for increasing flow, certainly will improve flow velocity, shower nozzle resistance to flow output causes water pump operation power to improve, and because of flow velocity, increase in pipeline, cause water resistance to increase considerably, pump motor, for maintaining flow, just need to keep operation under higher operate power, the energy consumption that has greatly increased whole system, haves much room for improvement.
For addressing the above problem, China Patent Publication No. is CN202255076U, a kind of water distribution uniformity device of realizing under counterflow cooling tower unsteady flow is disclosed, it comprises water inlet pipe (1) and horizontal water-locator, in cooling tower body, on the delivery port of water inlet pipe (1), horizontal water-locator is installed, it is characterized in that described horizontal water-locator comprises a plurality of water distributors (14) and water-distribution nozzle (12), the water inlet of each water distributor (14) is connected with water inlet pipe (1), a plurality of water-distribution nozzles (12) are arranged on respectively on the body of corresponding water distributor (14), a plurality of water-distribution nozzles (12) on each water distributor (14) are communicated with, each water-distribution nozzle (12) is all higher than water distributor (14).This technical scheme is according to communicating pipe equilibrium principle, when the water-distribution nozzle water yield close to main pipeline is many, must overcome terrestrial gravitation, at this moment water-distribution nozzle will produce counter-pressure, this counter-pressure is applied on main pipeline, pass to the water-distribution nozzle that water level is less compared with low wash water, because main pipeline is each water-distribution nozzle of UNICOM, at this moment due to balance pipe principle will each water-distribution nozzle of balance water level, make each water-distribution nozzle at same water level water distribution, thereby reach the object of water distribution uniformity, but due to the water-distribution nozzle of this technical scheme apopore for offering on pipeline straight up, although can reach in actual motion, between adjacent counterflow cooling tower, to reach water distribution even, but its apopore outlet effect is not good, can not effectively spray cooling, cooling effectiveness is lower, have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of water distribution that effectively reaches between counterflow cooling tower evenly and effectively to reduce water consumption and energy consumption, improve the counter-flow cooling tower multilayer water-distributing device of cooling effectiveness.
Key problem in technology of the present invention is the upper and lower multilayer setting of the arm of water distribution pipe, and control water-distribution nozzle quantity on every layer of arm and the height between levels arm, thereby it is even to realize between a plurality of counterflow cooling towers water distribution, and greatly reduce the energy consumption of water pump, make full use of film-cooled heat, improve cooling effectiveness.Its concrete technical scheme is: a kind of counter-flow cooling tower multilayer water-distributing device, comprise the water distribution pipe that is arranged at the inner or outer water inlet pipe straight up of tower body and is connected and is arranged at filler top with water inlet pipe, it is characterized in that described water distribution pipe comprises at least 2 arms and is arranged at the water-distribution nozzle on arm, described branch interval certain altitude is successively arranged on water inlet pipe.
As preferably, on described orlop arm, water-distribution nozzle quantity is pressed 10% ~ 50% flow design of counter-flow cooling tower design maximum flow.By this kind of setting, can in the situation that flow of inlet water is lower, realize lower floor's arm water distribution uniformity.
As preferably, described water-distribution nozzle is rotary nozzle or fixing shower nozzle.
As preferably, the setting of staggering of levels arm.Can be in the situation that flow of inlet water be large by this kind of setting, multilayer arm is unified water distribution, better utilizes film-cooled heat, and reduces the low-priced phenomenon of water, reduces water consumption.
As preferably, the setting of mutually staggering of the water-distribution nozzle on described levels arm.
As preferably, levels arm height is according to the bore of water-distribution nozzle, and pipe flow speed, water level pressure reduction calculate.By this kind of setting, can effectively control water inlet intraductal pressure, reduce pump energy consumption.
Beneficial effect of the present invention: can realize water distribution uniformity under the different flow of water inlet pipe, and additionally not increase pipeline water resistance, reach and select low-lift pump, reduce the object of pump energy consumption; Water distribution uniformity when cooling tower can be realized changes in flow rate, improve cooling tower cooling effectiveness, simultaneously because each tower is the U-shaped pipeline principle that connects house steward, preferential lower floor water distribution while forcing each tower low discharge, so just realize the evenly minute water between each tower, realized evenly minute water and the water distribution of Cooling Towers when changes in flow rate.This device is made simple, easy for installation, effectively reduces operating cost.
