Abstract
The invention discloses a volute mixed flow water turbine unit special for a cooling tower. The volute mixed flow water turbine unit special for the cooling tower is composed of a middle volute mixed flow water turbine, an upper fan and a lower water distributor. The volute mixed flow water turbine is composed of a horizontal cavity volute and a turbine vane system mounted inside the central hollow portion of the horizontal cavity volute; the extending portion of the volute is a cavity water inlet pipe; from the tangent intersection of the cavity water inlet pipe and the volute, a horizontal water outlet is formed around the inner wall of a volute housing, and the water inlet pipe is communicated with the draft tube of a circulating water system. The volute mixed flow water turbine unit special for the cooling tower is simple in structure, small in size, free from power consumption, noise and maintenance, low in drifting loss and very applicable to supporting low-cost operation of the cooling tower of a small building.
Description
Technical field
The present invention relates to the special volute mixed-flow type water turbine group of cooling tower and belong to field of central air-conditioning, particularly relate to a kind of cooling tower unit.
Background technique
Traditional air-condition cooling tower is electric fan type, and the motor namely installed by tower top drives tower internal fan to rotate, and realizes the object that air water heat exchange reaches cooling.Its shortcoming is: power consumption is high, noise is large, cannot ensure safe operation under explosion-proof, high-risk environment, and gas-water ratio is difficult to be stabilized in the optimum state, affects cold effect.The water loss that wafts is large, and need frequent amount of makeup water, maintenance work amount is large.The patent No. is 200820228871.9, and denomination of invention is the utility model patent of " exempting from electric-energy cooling tower volute mixed flow turbine ", preferably resolve above-mentioned defect, but it is for building.
Summary of the invention
The object of this invention is to provide a kind of one that proposes without power consumption, abate the noise, reduce drift ice loss, structure is simple, the special volute mixed-flow type water turbine group of reliable small-sized cooling tower.
The object of the invention is to realize as follows: the special volute mixed-flow type water turbine group of a kind of cooling tower, by the volute mixed-flow type water turbine at middle part, the fan on top, the water-dispensing device three part composition of bottom, volute mixed-flow type water turbine is fanned system two-part by horizontal cavity spiral case with the wheel being installed in its cavity place of central authorities and is formed, spiral case extension is cavity intake pipe, begin from this pipe and spiral case tangent line intersection, ring volute body madial wall has horizontal water outlet narrow orifice, intake pipe is communicated with the draft tube of circulation, on spiral case, lower end and be all connected with to connect and say dish, wheel fan system is by fan shaft, wear the axle sleeve that it is outer from top to bottom, on, in, lower flange, the circular wheel flabellum of center drilling, spring, nut forms, axle sleeve and upper, in, lower flange, the solar disk that connects of spiral case upper-end surface is connected in turn, the interface disc of spiral case lower end surface connect in turn be equipped with spiral case above the flange plate of three flange plate positional symmetry, the flange plate of bottom and outlet pipe, water-dispensing device is communicated with in turn.
The special volute mixed-flow type water turbine group of described cooling tower, all have keyway in fan shaft bottom and wheel flabellum center bore inner wall, wheel flabellum is that key is connected with fan shaft.
Advantage implementation structure of the present invention is simple, and compact, zero power consumption, noise free, freedom from repairs, the water loss that wafts is minimum, is very suitable for supporting aedicula cooling tower low cost movement.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention;
Fig. 2 is volute mixed-flow type water turbine decomposition texture schematic diagram.
Embodiment:
See shown in Fig. 1 and Fig. 2, the special volute mixed-flow type water turbine group of cooling tower is made up of the volute mixed-flow type water turbine at middle part, the fan 1 on top, water-dispensing device 8 three part of bottom.The wheel that volute mixed-flow type water turbine is located by horizontal cavity spiral case 6 and its central authorities cavity of installing is fanned system two-part and is formed.Spiral case 6 extension is cavity intake pipe 9, begins from this pipe and spiral case 6 tangent line intersection, and ring snail 6 case inside wall has horizontal water outlet narrow orifice 15.Intake pipe 9 is communicated with the draft tube of center air-condition circle water system.The upper and lower end face of spiral case 6 is all connected with to connect says dish 16.Wheel fan system is by fan shaft 2, and wear the axle sleeve 3 that it is outer from top to bottom, upper, middle and lower flange plate 4,5,11, the circular wheel flabellum 12 of center drilling, spring 13, nut 14 forms.Bearing and water seal is equiped with on the fan shaft 2 of corresponding position, axle sleeve 3 lower end.Axle sleeve 3 lower end is connected with flange plate 4, flange plate 4 with in, connecing of lower flange 5.11 and spiral case 6 upper-end surface say dish 16 and be connected in turn.Fan shaft 2 bottom and wheel flabellum 12 center bore inner wall all have keyway 10, and wheel flabellum 12 is connected with fan shaft 2 by key.Wheel flabellum 12 is said with horizontal water outlet Di on spiral case 6 madial wall and is in same level position ingeniously.The connecing of spiral case 6 lower end surface say dish 16 be connected with in turn with spiral case 6 above the flange plate of three flange plate positional symmetry, the flange plate being positioned at bottom is communicated with outlet pipe 7, water-dispensing device 8, all over boiling water hole on water-dispensing device 8.
High temperature tail water from center air-condition circle water system enters spiral case 6 through draft tube, intake pipe 9, and red switch wheel flabellum 12, interlock fan shaft 2, makes fan 1 rotate.The tail water entering spiral case 6 enters water-dispensing device 8 through outlet pipe 7, and current are disperseed to fall from each water hole, and fan 1 brute force drains the heat distributed when tail water falls, and its water temperature is reduced rapidly, and the low temperature tail water of lower backwardness is pumped into center air-condition circle water system again.
Above-described specific embodiment; object of the present invention, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
