Description
Technical Field
The utility model relates to a whirl nozzle for cooling tower.
Background
The spray nozzle is a common splashing device of a cooling tower of a thermal power plant, strands of water can be changed into small water drops through the spray nozzle, the small water drops are uniformly sprayed on a filler at the lower part as much as possible, and the granularity of the sprayed water drops directly influences the efficiency, investment and energy consumption of the cooling tower; the existing cooling tower swirl nozzle comprises a bracket, a conical guide shell and a joint connected to the upper end of the guide shell, wherein the bottom of the bracket is connected with a rotatable water distribution wheel, a fixed check ring is arranged around the water distribution wheel, and the check ring is provided with a plurality of diversion channels; when the circulating water spraying device is used, circulating water falls and flows out of the guide cylinder, the water distributing wheel is pushed to rotate and is collided with water flow to form water drops, and the water drops are further dispersed and sprayed through the water distributing groove of the check ring; but the granularity of the sprayed water drops is difficult to control, the defect of larger granularity of the water drops still exists, the heat dissipation effect is poor, the efficiency of the cooling tower is influenced, and the energy consumption is increased.
Disclosure of Invention
The utility model aims at the aforesaid that prior art exists is not enough, provides a cooling tower whirl nozzle, and its steerable granularity that sprays the water droplet, improves the radiating effect to improve the efficiency of cooling tower and reduce the energy consumption.
In order to achieve the purpose, the swirl nozzle of the cooling tower comprises a bracket, a conical guide cylinder and a joint connected with the upper end of the guide cylinder; the guide flow device is characterized in that a guide flow spiral cone is arranged in the guide flow cylinder, the guide flow spiral cone comprises a central shaft and spiral blades fixedly connected with the central shaft, the outer diameter of the upper end of each spiral blade is larger than that of the lower end of each spiral blade, the outer edges of the spiral blades are in contact with the inner wall of the guide flow cylinder, a plurality of guide flow holes are formed in the side wall of the guide flow cylinder, and the guide flow holes are all positioned in the tangential direction of the guide flow cylinder;
when the circulating water cooling device is used, circulating water flows downwards and starts to rotate under the action of the diversion spiral cone, and the water flow is continuously jetted out of the diversion cylinder through the diversion holes under the action of the rotating centrifugal force to be cooled in air; the particle size of sprayed water drops can be controlled through the inner diameter of the flow guide hole, the heat dissipation effect is improved, the flow guide hole is positioned in the tangential direction, the water flow is conveniently thrown out in the tangential direction, the spraying efficiency is improved, and therefore the efficiency of the cooling tower is improved, and the energy consumption is reduced;
as a further improvement of the utility model, the bottom of the bracket is fixedly connected with a flow guide seat, the lower end of the flow guide cylinder is arranged in an inner hole of the flow guide seat, and the flow guide seat is provided with a plurality of flow guide grooves which are bent in the radial direction around the inner hole; a small part of residual water flow is thrown out through the diversion grooves of the diversion seat and is cooled in the air, so that the efficiency of the cooling tower is further improved;
to sum up, the utility model discloses steerable granularity of spraying the water droplet, improve the radiating effect to improve the efficiency of cooling tower and reduce the energy consumption.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, the cooling tower swirl nozzle of the embodiment includes a bracket 1, a conical guide shell 2, and a joint 3 coupled to an upper end of the guide shell 2; a flow guide spiral cone is arranged in the flow guide cylinder 2, the flow guide spiral cone comprises a central shaft 4 and a spiral blade 5 fixedly connected with the central shaft in a welding mode, the outer diameter of the upper end of the spiral blade 5 is larger than that of the lower end of the spiral blade 5, the outer edge of the spiral blade 5 is in contact with the inner wall of the flow guide cylinder 2, a plurality of flow guide holes 6 are formed in the side wall of the flow guide cylinder 2, and the flow guide holes 6 are all located in the tangential direction of the flow guide cylinder 2; the bottom of the bracket 1 is integrally and fixedly connected with a guide seat 7, the lower end of the guide cylinder 2 is arranged in an inner hole of the guide seat 7, and the guide seat 7 is provided with a plurality of guide grooves 8 which surround the inner hole and are bent in the radial direction;
when the water cooling device is used, circulating water enters the guide shell 2 through the connector 3, and starts to rotate while flowing downwards under the action of the spiral blades 5 of the guide spiral cone, most of the water is continuously sprayed out of the guide shell 2 through the guide holes 6 under the action of the rotating centrifugal force, so that the water is cooled in the air, and a small part of the residual water is thrown out through the guide grooves 8 of the guide seat 7 and is cooled in the air; the granularity of spraying the water droplet can be controlled through the inner diameter of the guide flow hole 6, the heat dissipation effect is improved, the guide flow hole 6 is positioned on the tangent direction of the guide flow cylinder 2, the water flow can be conveniently thrown out tangentially, the spraying efficiency is improved, and therefore the efficiency of the cooling tower is improved, and the energy consumption is reduced.
