Description

Turbine of cooling tower

This creation belongs to the water turbine, and particularly relates to a water turbine structure used to replace the traditional motor and reducer to cool the water tower.

The cooling structure of the conventional water tower is a technology that uses a motor and a reducer to drive the fan for heat dissipation. Since the drive motor needs to consume power, it will inevitably cause energy loss. Moreover, the motor, reducer and its transmission shaft, etc., not only have a complicated structure, but also require Frequent maintenance, greatly increasing the cost of installation and maintenance, coupled with the vibration of the motor and reducer during operation, will also affect the life of the entire cooling structure, and produce serious noise and damage the community peace.

To this end, there have been improved designs for the aforementioned deficiencies. The way is to use hydraulic turbines to replace traditional motors and reducers to improve the design of cooling towers. Turbine is a device that converts water pressure into rotating mechanical power. Its principle is widely used in hydroelectric power generation facilities. The special turbine for cooling water tower is to use the excess pressure in the water tower system to drive the turbine to rotate, and to replace the traditional motor to drive the fan. structure. Limited by the scale of the water flow of the water tower, it is necessary to develop a low-flow, low-head special turbine suitable for the circulating water system to achieve cost and energy saving requirements.

The common hydraulic turbines are roughly the following:

(1) Tubular turbine, which is installed outside the cooling water tower, although it is not driven by a motor, it still needs to retain the original transmission shaft and reducer, making it inefficient, requiring greater return water pressure, and severe vibration , Must also carry out more maintenance work;

(2) The double-click turbine, whose working principle is to let the circulating water enter the inlet of the turbine and flow out from the side after two impacts on the internal runner to complete the work. The radial force of the runner spindle in this method is easily uneven, resulting in Bearing wear and huge vibration and noise, and the water flow easily forms vortex in the turbine casing, causing resistance and affecting the overall efficiency;

(3) High speed ratio turbine, which is mainly equipped with a gear box on the structure of the turbine to reduce the speed. The overall height of this structure is too high. It is necessary to reduce the base position height of the original reducer or increase the positioning height of the original fan. The effect of air extraction will be greatly reduced, and the addition of a reduction box will cause a large vibration value, a large water pressure demand, a reduction in transmission efficiency and an increase in failure rate.

Therefore, to summarize the advantages and disadvantages of the aforementioned various designs, this creation mainly uses low speed ratio turbines as the basis, based on different user cooling system parameter requirements, excess pressure, flow and other data analysis, and then obtains the relevant technical parameters of each structural component of the turbine, According to these data in the design and production link, the targeted circulation area, guide vane angle, runner diameter and blade shape of each node of the shell are targeted to meet the user's process and use requirements.

According to the aforementioned problems and improvement measures, after long-term R&D and implementation, the creator can finally complete the turbine of this cooling tower.

The main purpose of this creation is to provide a cooling water tower turbine, which does not require The use of motors and speed reducers reduces power consumption, which is both environmentally friendly and cost-saving.

Another purpose of this creation is to provide a cooling tower water turbine, which simplifies the overall structure of the turbine, not only runs more smoothly, but also reduces maintenance time and costs.

Another purpose of this creation is to provide a water tower cooling turbine, which greatly reduces the vibration of the water tower body, improves the service life, and obtains a quieter use space due to the reduction of vibration.

The turbine of the cooling water tower, which can achieve the foregoing purpose, includes a casing and a turbine.

The casing has a movable space inside, and the casing has an annular pipe surrounding the movable space. The annular pipe is connected to a water inlet pipe to introduce water flow to bypass the annular pipe and evenly flow into the movable space from the surroundings; In the movable space, the turbine has a guide space penetrating from the periphery to the middle, and a transmission shaft is provided in the middle of the turbine. A turbine blade is provided around the transmission shaft, and the turbine blade is inserted into the guide space to make the The inlet of the deflector space around the turbine is connected to the annular duct to guide the water flow into the deflector space. After pushing the turbine blade to drive the transmission shaft to rotate, it is discharged from the outlet of the deflector space in the middle of the turbine.

The hydraulic turbine structure completed by the foregoing is installed on a water tower. When in use, it will first be led into the water flow by the water inlet pipeline, and then push the turbine blade to drive the transmission shaft to rotate. The transmission shaft is extendedly connected to a cooling fan. The water flow drives the turbine to drive the cooling fan to rotate via the transmission shaft to cool the water flow.

After the work, the water flow will be concentrated to the outlet with a water collecting tank, and a plurality of water distribution pipes are arranged around the water collecting tank, so that the water flow is evenly distributed from the middle to the outside to improve the distribution of water on one side of the traditional cooling water tower The problem of uneven pressure.

Through the foregoing description, the advantages of this creation over conventional technology are:

1. This creation is more power-saving, it can work all year round and work by the turbine, no motor is needed to drive the fan

2. The service life of this creation is longer, because there is no motor, reducer and transmission shaft and other machinery, so the maintenance cost of the equipment is reduced, and the product life is also increased;

3. This creation is more water-saving, which can be adjusted by temperature control to adjust the fan speed, so that the speed of the turbine can be adjusted according to the season (ambient temperature), which can reduce the evaporation of water and reduce the rate of floating water;

4. This creation has low vibration and low noise. It does not require a motor to run, naturally reducing vibration and reducing noise life:

5. This creative wisdom controls and improves the efficiency. It can combine the temperature sensor with the control system, so that the administrator only needs to set the required water temperature to adjust.

6. This creation is more environmentally friendly, it reduces the time for maintenance and maintenance, also reduces the leakage of oil products and pollutes the quality of circulating water, and can further avoid the failure rate and heat exchange efficiency of related equipment.

7. This creation is safer. Since the hydraulic turbine has been used for many years, the use of hydraulic residual pressure to drive without electricity fundamentally eliminates the risk of equipment leakage or ignition of combustibles.
