Description

Energy-saving water turbine

technical field

The utility model relates to a cooling tower system, which is a novel energy-saving water turbine.

Background technique

In the cooling device of the current cooling tower system, hot water is poured down from the height of the tower. During the falling process, the rotating fan on the top exhausts the heat from the water to achieve the purpose of cooling. The rotation of the fan is driven by the rotation of the motor and the reduction box device. The long-term operation of the motor will consume a large amount of electricity. At the same time, the purchase, installation and maintenance of the gearbox also require cost, and part of the energy will be lost during the transmission process of the gearbox. At the same time, when the cooling tower system pours hot water down, it generally adopts a decentralized method, which will generate a large amount of floating water during the working process. First, it causes a waste of water resources, and second, it also affects the cooling effect. The third is the impact on the environment. However, the sprinklers of the existing water outlet systems on the market are separate, which will take up a large space, thereby affecting the flow of hot air.

In addition, the positions of the water inlet and the water outlet also vary with different models of cooling towers. If the change is too large, it will increase the amount of work and prolong the working cycle, and if it is not done well, it will damage the cooling tower and water pipe system. Existing water inlets generally have a fixed diameter and a fixed number, which cannot be adjusted in different situations and cannot fully utilize energy.

Utility model content

In order to solve the above problems, the utility model provides an energy-saving water turbine that utilizes the energy of the hot water to increase the lift, and drives the fan blades to rotate through the water turbine, so as to achieve heat extraction.

The technical scheme adopted in the utility model is as follows:

An energy-saving water turbine, comprising an outer box, a bearing, a main shaft, a main shaft impeller arranged on the main shaft, and a fan arranged on the main shaft. Drive for the main shaft impeller.

The driving device of the main shaft impeller includes an inner box inside the outer box and several water spray ports arranged on the inner box, the blades of the main shaft impeller are located between the outer box and the inner box, and the inner box The bottom or side of the body is connected to the water inlet, and the outer box is provided with a water outlet mechanism, which is in the form of a water outlet connected to the side of the outer box.

The water spray ports are distributed along the outer circumference of the inner box in a 360-degree direction, and the high-pressure water is sprayed from the water spray ports to impact the impeller of the main shaft from the inside to the outside, thereby driving the fan on the main shaft to rotate.

Each of the water spouts is an independent part, which is installed in a plug-in type. When not inserted, a baffle is used to seal the insertion port; the cross-sectional shape of the water spouts is rectangular; the number and cross-sectional size of the water spouts are based on the actual Settings are required.

The included angle between the water spraying direction of the water spray port and the arc tangent of the location is between 0°-60° or 120°-180°.

The water outlet mechanism is in the form of a sprinkler, which adopts an integrated design with the water turbine. This design makes the volume of the whole device smaller and is more conducive to the ventilation of the cooling tower space; the sprinkler includes a sprinkler impeller, and a water sprinkler. The sprinkler water pipe connected to the impeller.

The water inlet is connected vertically from the bottom of the inner box, and the sprinkler impeller is nested outside the main shaft impeller; or the water inlet is connected horizontally from the side of the inner box, and the sprinkler impeller is correspondingly arranged under the main shaft impeller. The above methods need to be selected according to the specific conditions of the inlet and outlet water systems of different cooling towers, and how to modify the original system to a minimum.

A slant guide plate is arranged between the impeller of the sprinkler and the impeller of the main shaft.

The lower end of the sprinkler water pipe is provided with several vertically downward short pipes.

Compared with the prior art, the utility model has the following beneficial effects: (1) the electric motor and the reducer device are canceled, which saves electric power; (2) the residual inertia after the water is sprayed to the impeller is fully utilized to drive the sprinkler to rotate to achieve uniform water sprinkling (3) Due to the integrated design of the sprinkler and the water turbine, the volume of the whole device is smaller, the height of the space is saved, and the stroke of the hot water is increased, thereby improving the cooling efficiency; (4) Since the sprinkler The lower end of the water pipe is provided with a short pipe to avoid the phenomenon of floating water. (5) Due to the way of spraying water from the inside out, the water inlet can be located on the side or the bottom, which is convenient for the transformation and utilization of the existing cooling tower.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the overall structure of the energy-saving water turbine is that two circular boxes are nested together, that is, the outer box 6 and the inner box 2 are nested together. The bottom of the inner box 2 (as shown in FIG. 1 ) or the side (as shown in FIG. 3 ) is connected with the water inlet 1 , and the side of the outer box 6 is connected with the water outlet 11 . The high-pressure water flow enters the inner box body 2 from the water inlet 1, and flows out from the water outlet 11 after hitting the impeller blades.

When the water outlet mechanism adopts the form of a sprinkler integrated with the water turbine, the sprinkler can be divided into two different structures according to the different water inlet positions, as shown in Figure 5 and Figure 6. It is a nested type: water enters from the vertical direction, The sprinkler impeller 8 is nested outside the main shaft impeller 4; as shown in Figs.

The pressure water coming in through the water inlet 1 enters the inner box body 2, and there are no less than four nozzles 3 around the inner box body 2, and the water outlet line of each water nozzle 3 is tangent to the arc of the position form a certain angle, and the value of the angle is 0° to 60° or 120° to 180°. With this water outlet direction close to the tangent of the circumference, the high-speed water flow is ejected outward to impact the main shaft impeller 4 on the main shaft 5, and make the Rotate, the main shaft 5 connected with it also rotates at the same time, and then drive the fan blade connected to the upper end of the main shaft 5 to rotate, and the hot air is discharged.

After the water flow hits the main shaft impeller 4, it still has a certain speed. This part of water moves between the main shaft impeller 4 and the outer box body 6, impacts the sprinkler impeller 8 through the guide slant plate 7, and drives the sprinkler to rotate. The absolute value of the included angle between the inclination of the guide swash plate 7 and the direction of motion is between 5° and 60°. The maximum axial distance between the main shaft impeller 4, the sprinkler impeller 8 and the water spray port 3 is within 40 centimeters. This design makes full use of the kinetic energy of the water after impacting the main shaft impeller 4.

The water after impacting the sprinkler impeller 8 finally flows to the sprinkler water pipe 9, and the sprinkler water pipe 9 has several holes in the vertical downward direction for sprinkling water. The short pipe 10 is used to guide the water to flow vertically downward.
