Abstract
The invention relates to a circulating water cooling tower, in particular to a stepped air-inlet spray high-efficiency cooling tower, which comprises a water distribution plate, an air duct, a spray atomizing device connected with a high-pressure water inlet pipe, a water collector and a fan which are arranged in the body of the tower in sequence from bottom to top, wherein the upper part of the body of the tower is partitioned off into an atomizing chamber and the lower part thereof is partitioned off into an air guide chamber by the water distribution plate; the side wall of the air guide chamber is provided with the air inlet window of the air guide chamber; and the side wall of the lower end of the atomizing chamber is provided with the air inlet window of the atomizing chamber. In the invention, due to the fact that the position of the side wall of the lower end of the atomizing chamber is provided with the air inlet window of the atomizing chamber, the inlet air flow of the atomizing chamber is increased and the air flowing direction in the atomizing chamber is changed, and thereby, the heat exchange between air and water in the atomizing chamber is more sufficient, and finally, the cooling effect is better.
Description
Technical field
The present invention relates to a kind of circulating water cooling tower, relate in particular to a kind of stepped air-inlet spray high-efficiency cooling tower.
Background technology
Airintake direction is single in the Chang Yong spray cooling tower ubiquity spray chamber in the market, charge flow rate is less than normal, thereby has reduced cooling water at the heat of evaporation exchange capacity between aqueous vapor under the vaporific condition, influences the cooling capacity and the cooling-down effect of cooling tower.
Summary of the invention
For overcoming above-mentioned defective, the invention provides a kind of stepped air-inlet spray high-efficiency cooling tower of good cooling results.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of stepped air-inlet spray high-efficiency cooling tower, comprise the water distributing plate, ventilating duct, the spray atomization device of connection high-pressure intake pipe, water collection device, the blower fan that from bottom to top are installed in successively in the tower body, water distributing plate with the top of tower body be divided into spray chamber, the lower part is divided into air guiding chamber, offer air guiding chamber's air-inlet window on the wall side of air guiding chamber, offer the spray chamber air-inlet window on the lower end sidewall of described spray chamber.The present invention is provided with the spray chamber air-inlet window on the sidewall locations of spray chamber lower end, increased the air intake flow of spray chamber, has changed air-flow direction in the spray chamber, thereby makes between air water in the spray chamber heat exchange more abundant, finally makes cooling effect better.
As the further setting of such scheme, the bottom position of described spray chamber air-inlet window is higher than or flushes with the water distributing plate position, and the apical position of air guiding chamber's air-inlet window is lower than or flushes with the water distributing plate position.
Described spray chamber air-inlet window on the spray chamber sidewall locations, can be set to the symmetry a group or more.Described air guiding chamber air-inlet window on air guiding chamber's sidewall locations, can be set to the symmetry a group or more.Structural symmetric design makes the operation of whole tower more steady.
Stepped air-inlet spray high-efficiency cooling tower of the present invention, the negative pressure air that hot water not only sucks with spray chamber air-inlet window suction air and air guiding chamber under the vaporific condition of spray chamber in its tower carries out the exchange of one-level heat of evaporation, simultaneously under air guiding chamber's cloth water condition, suck air and under the negative pressure operating mode, carry out the dual evaporation heat exchange with the air guiding chamber air-inlet window, prolonged heat exchanger time between air water, enlarged heat transfer area between air water, cooling capacity strengthens under the constant prerequisite of energy consumption, cooling-down effect is remarkable.
In a word, the present invention makes its structure compact and reasonable more owing to adopted technique scheme, and profile is more elegant in appearance, and installation and maintenance are convenient; Cooling and energy-saving effect are more remarkable.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, stepped air-inlet spray high-efficiency cooling tower of the present invention, comprise water distributing plate 6, the ventilating duct 5 that from bottom to top is installed in successively in the tower body 12, spray atomization device 4, water collection device 2, the blower fan 1 that connects high-pressure intake pipe 9, water distributing plate 6 with the top of tower body 12 be divided into spray chamber 3, the lower part is divided into air guiding chamber 7, offer air guiding chamber's air-inlet window 10 on the wall side of air guiding chamber 7, offer spray chamber air-inlet window 11 on the lower end sidewall of spray chamber 3.The bottom position of spray chamber air-inlet window 11 is higher than or flushes with water distributing plate 6 positions, and the apical position of air guiding chamber's air-inlet window 10 is lower than or flushes with water distributing plate 6 positions.Spray chamber air-inlet window 11 on spray chamber 3 sidewall locations, can be set to the symmetry a group or more.Air guiding chamber's air-inlet window 10 on air guiding chamber's 7 sidewall locations, can be set to the symmetry a group or more.The below of tower body 12 is equipped with header tank 8.Certainly, water distributing plate 6 also can be provided with more than the one-level in tower body 12, promptly also can set up one or multi-channel water distributing plate 6 in the spray chamber 3.
Operation principle of the present invention is: cooling tower normally moves, the hot water that is cooled enters in the tower body 12 by high-pressure intake pipe 9 under design head more than needed, the hot water that is cooled in the high-pressure intake pipe 9 is given each spray atomization device 4 by the arm uniform distribution again, and the hot water that is cooled that sprays on each spray atomization device 4 shower nozzle forms fog in spray chamber 3; During blower fan 1 work, the negative pressure air in the air guiding chamber 7 that the water distributing pore on outdoor environment wet bulb air that fog that forms in the spray chamber 3 and spray chamber air-inlet window 11 suck and ventilating duct 5, the water distributing plate 6 sucks carries out the heat exchange of abundant fog gas under the negative pressure operating mode in spray chamber 3.The water droplet that forms after this fog gas heat exchange is evenly trickled down on water distributing plate 6, enters air guiding chamber 7 by the water distributing pore on the water distributing plate 6 again; In air guiding chamber 7, the water distribution water droplet under the negative pressure operating mode and the outdoor environment wet bulb air that sucks of air guiding chamber's air-inlet window 10 carry out the heat exchange of secondary aqueous vapor, the water droplet that forms after the heat exchange of secondary aqueous vapor confluxes and enter the cooling unit by gravity or adherence pressure in header tank 8.
The secondary negative pressure air that hot water not only sucks with spray chamber air-inlet window 11 suction air and air guiding chamber 7 under spray chamber 3 fog shape conditions in the cooling tower tower body 12 of the present invention carries out the exchange of one-level heat of evaporation, simultaneously under air guiding chamber's 7 cloth water conditions, suck air and under the negative pressure operating mode, carry out the dual evaporation heat exchange with air guiding chamber air-inlet window 10, prolonged heat exchanger time between air water, enlarge heat transfer area between air water, under the constant prerequisite of energy consumption, strengthened the cooling tower cooling capacity, cooling-down effect is remarkable.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
