Abstract
A water wheel type fan for a cooling tower belongs to the technical field of cooling and ventilating equipment. Mainly comprises an impeller 7, a transmission shaft 5, a water turbine 8 with a water inlet pipe 4 and a water outlet pipe 1, and the like, wherein a water wheel 9 is arranged in the water turbine. The high-speed hot water output by the refrigeration equipment can impact the water wheel to rotate the water wheel and drive the impeller to rotate to generate air quantity, so that heat exchange is realized in the cooling tower. The water energy of hot water can be effectively utilized, self-provided power energy consumption is not needed, high-frequency noise generated by motor transmission can be avoided, and the energy-saving and noise-reducing water heater has ideal energy-saving and noise-reducing effects.
Description
The utility model relates to a kind of used for cooling tower water wheel type blower fan, belongs to the cooling channel equipment technical field in the fluid machinery.
Existing used for cooling tower blower fan mainly is made up of impeller and motor, the high-frequency noise that its motor and blower fan produce is outwards propagated far away, be difficult to effectively control noise, and long-term operation easy burn-out motor, for can realize effectively that cooling tower is efficient, energy-conservation, the operational effect of low noise etc., prior art mainly is optimized design by the impeller to blower fan of cooling tower and drive motor is rationally matched, but still can not satisfy usage requirement to being installed in the higher cooling tower of city neighborhood or other environmental requirements, and energy-saving effect is also undesirable.
The purpose of this utility model provides a kind of reasonable in design, has the used for cooling tower blower fan of comparatively ideal energy-saving and noise-reducing effect.
The utility model is a used for cooling tower water wheel type blower fan, comprise impeller and transmission shaft, it is characterized in that also comprising simultaneously that the water turbine of bringing water pipe and outlet pipe into, water turbine place between intake pipe and the outlet pipe, be provided with water wheels in the water turbine, impeller and water wheels place the transmission shaft two ends respectively.The utility model is used the working principle of water turbine, by the water wheels in the high speed flow of hot water impulse water turbine of being exported by chiller plant in the intake pipe, makes the water wheels rotation, by the rotation of transmission shaft drives impeller, produces air quantity, thereby realize heat exchange in cooling tower again.
Also can be provided with retarder on the described transmission shaft, be beneficial to regulate the rotational speed of impeller; Also can be provided with the connecting tube of the band modulating valve in parallel between described intake pipe and the outlet pipe, with the flow of hot water in control and the adjusting water turbine with water turbine.
Designing requirement according to cooling tower, water wheel type blower fan described in the utility model can place the bottom of cooling tower tower body or top, side, as place the bottom of cooling tower tower body, described water wheel type blower fan can be the structural type that impeller places the water turbine bottom, simultaneously can shunt be set, fall to contacting impeller to avoid cooling water at upper impeller; As placing the top of cooling tower tower body, described water wheel type blower fan can be the structural type that impeller places water turbine top; As placing the side of cooling tower tower body, described water wheel type blower fan can be the structural type that is provided with about impeller and water turbine.
The utility model reasonable in design, use the working principle of water turbine, adopt the structural design of water wheels and impeller, no electric machine, fundamentally changed the structural type of existing blower fan, can effectively utilize self water of hot water can save power consumption, can avoid again because the high-frequency noise that electric-motor-driving produces; Simultaneously, place the bottom of cooling tower as the water wheel type blower fan, and dispose shunt, the most of noise in the time of more making cooling tower work is absorbed by air-flow and consumes in tower body.And the setting of retarder and modulating valve makes the utility model can require according to the overall operation of various cooling towers to regulate at any time, with realize that cooling tower is efficient, energy-conservation, the optimum operation effect of low noise etc.The utility model be installed in the cooling tower can with the supporting uses of polytype cooling tower such as reverse-flow circular tower, reverse-flow square tower, the square tower of cross-flow type, reverse-flow assembly unit tower, be used for the recycling of operation of air conditioning systems cooling water.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 places the structural representation of water turbine bottom for the utility model impeller;
Fig. 2 is an A-A face sectional view shown in Figure 1.
Fig. 3 is the structural representation of the utility model in cooling tower;
Fig. 4 places the structural representation on water turbine top for the utility model impeller.
Below in conjunction with embodiment the utility model is further described:
The utility model is mainly by impeller 7, transmission shaft 5, intake pipe 4, outlet pipe 1, and water turbine 8 formations such as grade, water turbine 8 places between intake pipe 4 and the outlet pipe 1, is provided with water wheels 9 in the water turbine 8, and impeller 7 and water wheels 9 place the two ends of transmission shaft 5 respectively; Also can be provided with retarder 6 on the transmission shaft 5, also can be provided with the connecting tube 3 of band modulating valve 2 between intake pipe 4 and the outlet pipe 1, connecting tube 3 is in parallel with water turbine 8, and accompanying drawing 1 is the structural type that impeller 7 places water turbine 8 bottoms, and accompanying drawing 4 places the structural type on water turbine 8 tops for impeller 7.
With accompanying drawing 1 described structural type is example, as shown in Figure 3, the utility model is installed on the lower position in the tower body 10 of cooling tower, intake pipe 4 extends to the outer hot-water line of exporting with chiller plant of tower body and is connected, outlet pipe 1 connects water distributor 11, at upper impeller shunt 13 is set simultaneously.During work, after the hot water of chiller plant output enters cooling tower by intake pipe 4,, make water wheels 9 rotations,, produce air quantity, blow to cooling tower top by 7 rotations of transmission shaft 5 drives impeller by the water wheels 9 in the high speed hot water impulse water turbine in the intake pipe 8; Meanwhile, hot water continues upwards to enter water distributor along outlet pipe 1 after impacting water wheels, spray out in the inflow filler 12 by the aperture on the water distributor, distinguished and admirablely carry out sufficient heat exchange with impeller 7 produces, hot water cools off the whereabouts after heat exchange, fall into by shunt 13 in the water-collecting tray 14 of tower body bottom and and flow to chiller plant, realize the circulating and recovering of cooling water by water-output flange 15 external delivery pipes.The rotating speed of retarder 6 may command and adjusting impeller 7; High speed hot water can make a part of high speed hot water in the intake pipe 4 directly flow to outlet pipe 1 by connecting tube by the flow of water turbine 8 in the modulating valve 2 can regulate intake pipes 4.The utility model need not self-powered's energy consumption through actual motion, and ambient noise can reduce by 10～15 decibels, and the energy-saving and noise-reducing effect is obvious.
