Description
Technical field
The utility model belongs to a kind of water tower device that can reduce circulating water temperature in service, particularly a kind of spiral case rotation composite type spray equipment.
Background technology
At present; The gravity-flow ventilation cooling tower generally adopts vertical shaft that hot water is delivered to the water distribution elevation; Lean on slot type or tubular type water distribution system with water distribution to the section of whole tower; With spray equipment water is become little water droplet again, be spread across equably on the filler then as far as possible, the uniformity of trickle is very big to the cooling effect influence of cooling tower.
Chinese patent CN201297866Y discloses a kind of " energy-conservation rotary heat-exchanger rig "; It mainly is made up of support, water guide cone, water spreading disc etc.; A water supply connector is arranged at the top of support, and the water guide cone is fixed on the bottom of support through minor axis, and is positioned at the below of water supply connector; The blade that has several and its center line to have angle on the water spreading disc, and be installed on the minor axis through upper and lower bearing.This patent vertically is ejected into water on the water guide cone through water supply connector, utilize the water guide cone with water divide uniformly to around, utilize the angle between current and the blade to promote the water spreading disc rotation, and with blade collision back refinement, be the misty rain shape to around sprinkle.Though the uniformity of this patent trickle is better, and improved the heat exchange effect of water and air, water droplet is still thin inadequately, and the heat exchange effect is desirable not enough.
Summary of the invention
The technical problem that the utility model will solve is, overcomes poor, the unfavorable problem of heat exchange effect of water droplet refinement that existing spray heat-exchanger rig exists, and the spiral case rotation composite type spray equipment of a kind of atomizing, good effect of heat exchange is provided.
The utility model has a support, in the bottom of support the water guide cone is housed, and the water guide cone is fixed on the support through minor axis; The water spreading disc that has several blades is housed on minor axis; Water spreading disc is installed on the minor axis through upper bearing (metal) and lower bearing, and its special character is on the top of support spiral case to be installed; A water inlet is arranged in the side of spiral case; In the bottom of spiral case one and the corresponding delivery port of water guide cone are arranged, utilize spiral case to produce and the perpendicular rotary water current of water spreading disc blade, promote the water spreading disc rotation.
Described spiral case is made up of upper volute body and following volute body, bonds together between upper volute body and the following volute body.
Also has a tapered protrusion on the top of upper volute body, with the rotation of further reinforcement current in spiral case.
Several corresponding each other locating pieces are arranged respectively on upper volute body and following volute body; On the locating piece of following volute body, a securing dowel is arranged; A pin-and-hole that matches with securing dowel is arranged on the locating piece of upper volute body, accurately locate to guarantee upper volute body and following volute body.
The utility model is installed spiral case above support, and in the lateral inflow of spiral case, bottom water outlet; Water is rotated in spiral case, produce rotary water current, the flow direction and the blade on the water spreading disc of rotary water current are perpendicular; Thereby the impact of current and blade is bigger, and the speed of water spreading disc rotation is also faster, and the water droplet that produces after the current impact blades is littler; Atomizing, heat exchange better effects if; The splash scope is big, the trickle characteristic is good, reached the water distribution uniformity purpose, has further improved the cooling effectiveness of water tower, and water tower can be saved fire coal more than 0.35% after using the utility model.

Fig. 2 is A-A cutaway view of Fig. 1;
Fig. 3 is B-B cutaway view of Fig. 2.
The specific embodiment
Shown in accompanying drawing, the utility model has a support 8, and support 8 is made up of three muscle shape bale handles, in the bottom of support 8 water guide cone 5 is housed, and water guide cone 5 is the arc tapered roller of band point in the middle of the top, and the bottom is the cambered surface that the edge upwarps, thereby with around the current deflecting; Described water guide cone 5 is fixed on the support 8 through minor axis 9, is interference fit between water guide cone 5, minor axis 9 and the support 8, perhaps sticks with glue to be connected together; A water spreading disc 7 is housed on minor axis 9, and water spreading disc 7 is made up of inner ring, outer ring, brace rod and several blades 6, and described blade 6 is arranged on the outer ring of water spreading disc 7; And an angle is arranged between the center line of blade 6 and water spreading disc 7; Promptly all blades 6 all are obliquely installed, and when current and blade 6 collisions, promote water spreading disc 7 rotations; And make the current refinement, be the misty rain shape to around sprinkle; Described water spreading disc 7 is installed on the minor axis 9 through upper bearing (metal) 12 and lower bearing 11, and is reliable to guarantee it; A plane bearing 10 also is installed on minor axis 9, and plane bearing 10 is between lower bearing 11 and support 8, to eliminate the friction between lower bearing 11 and the support 8; Top at support 8 is equipped with spiral case, and described spiral case is made up of upper volute body 1 and following volute body 2, bonds together between upper volute body 1 and the following volute body 2; In the side of spiral case a water inlet 3 is arranged, in the bottom of spiral case---promptly descend the bottom of volute body 2 that one and water guide cone 5 corresponding delivery ports 13 are arranged, utilize spiral case to produce rotary water current, promote the water spreading disc rotation; Described volute body down 2 adopts and is threaded onto on the support 8, below the delivery port 13 of following volute body 2, a taper 4 is installed also, with further raising discharge pressure; Also has a tapered protrusion 1a on the top of upper volute body 1, with the rotation of further reinforcement current in spiral case; Several corresponding each other locating piece 1b, 2b are arranged respectively on upper volute body 1 and following volute body 2; The quantity of locating piece 1b, 2b is not limit; Locating piece 1b, 2b are respectively three in the present embodiment; In actual use, locating piece 1b, 2b also can be two, four or more a plurality of, confirm according to actual needs; On the locating piece 2b of following volute body 2, a securing dowel 2a is arranged, a pin-and-hole that matches with securing dowel 2a is arranged on the locating piece 1b of upper volute body 1, accurately locate between upper volute body 1 and the following volute body 2 guaranteeing.
Operation principle: after the water tower vertical shaft is set up hydraulic pressure; The pressure that leans on water reduces resistance simultaneously at first through producing rotary water current in the spiral case, and this rotary water current ejects water on the water guide cone 5 through taper 4; Utilize water guide cone 5 with rotary water current divide uniformly to around; And vertically impinge upon on the blade 6 of water spreading disc 7, produce revolving force, promote water spreading disc 7 rotations; When flowing on water guide cone 5 surfaces, the water of fraction flows down from slit between water spreading disc 7 and the water guide cone 5; Clash into the water droplet of fixed-direction not unrestrained downwards in water through the rotation of water spreading disc 7 brace rods; Adjustment slit size; Can adjust the water yield of whereabouts, in the middle of the bottom of water spreading disc 7, produce the trickle district; A large amount of water is the blade 6 of vertical bump water spreading disc 7 under the effect of water guide cone 5 then, in the process of impact blades 6, produces tiny water droplet, equably to around sprinkle.Test shows that the utility model trickle is even, and does not have the trickle dead angle, thereby realizes the temperature-fall period of water distribution uniformity.
