Description

Hydropower residual pressure power generation device

This creation belongs to the field of generators, especially a water turbine power generation device with simple structure and easy erection and use. Traditionally, many pipelines use valves to decompress energy and waste energy. This patented device can reuse the residual pressure, which is both economical and environmentally friendly. .

The cooling water tower is a heat removal device that uses water as a coolant to absorb heat when the water circulates through the heat source equipment, and then through the heat sink, the heat absorbed by the water is evaporated and discharged into the atmosphere. During the period, the fan is used to accelerate the cooling effect. Finally, the purpose of heat dissipation is achieved.

In order to achieve the water circulation of the cooling tower, a motor or a reducer must be used to drive the water circulation, which results in a large amount of energy loss. However, only a part of these consumed energy produces useful work during the water circulation process, and the rest of the energy becomes meaningless loss during the water circulation process, resulting in the overall energy waste of the cooling water tower.

In fact, before the water cycle completes each work cycle, there will still be a small amount of residual pressure. The energy of these residual pressures may not be much, but in the process of repeated water cycles, the accumulated energy is also considerable. Calculating the size of the residual pressure and then properly applying it will definitely reduce energy waste and contribute to environmental protection.

Just like some water circulation systems sometimes when the process does not require a large flow, the water pump directly bypasses the output and returns it to the cooling water pool. The flow and pressure of this bypass are also a waste of energy.

In addition, some pipeline systems have natural gravity flow energy, and the traditional use of valves or pressure reducing devices to dissipate energy is also a waste of energy.

For this reason, the author of this case considered reusing the residual pressure of the water cycle. The method was to calculate the residual pressure of the water cycle, and then design suitable hydraulic turbines and generators to allow the water flow with residual pressure to generate electricity through the generator to achieve The effect of environmental protection and energy reduction. However, most of the current common generator equipment cannot effectively utilize the residual pressure of the cooling water tower, and it is difficult to achieve power generation efficiency; or, the existing generator equipment cannot be directly installed near the cooling water tower. Therefore, other design methods must be considered to achieve the patent claims of this creation.

A hydraulic turbine is a device that converts the kinetic energy of water flow into mechanical energy. It is mainly used in hydroelectric power generation facilities. It concentrates the water flow through natural water flow concentration locations or artificial dams, and uses water pipes to introduce water flow into the turbine to impact The water turbine rotates, so that the water turbine is connected to drive a generator to generate electricity.

Common water turbines generally have the following types: (1) Tubular turbine, which belongs to a kind of horizontal shaft turbine, that is, the water flow moves along the horizontal axis in the flow channel. It is mainly used in hydropower stations with low water head and large flow. Although it does not need to be driven by a motor, it still needs to retain the original The output shaft and reducer make it inefficient, require greater return water pressure, and have severe vibration, and more maintenance work must be carried out; (2) The working principle of the double-click water turbine is to let the circulating water enter the water inlet of the water turbine, and flow out from the side to complete the work after two impacts on the internal runner. Bearing wear and huge vibration and noise, and the water flow is easy to form eddy current in the turbine shell, causing resistance and affecting the overall efficiency; (3) High speed ratio water turbine, which mainly installs a gearbox on the structure of the water turbine to reduce the speed. The overall height of this structure is too high. It is necessary to reduce the base height of the original reducer to greatly reduce the efficiency, and there are more gearboxes. It will cause large vibration value, large water pressure demand, reduce transmission efficiency and increase failure rate.

Considering the advantages and disadvantages of the above-mentioned various designs, this creation is mainly based on the low speed ratio water turbine, and according to the data analysis of the system parameters, residual pressure, flow and other data of different cooling water towers, and then obtains the relevant technical parameters of the various structural components of the water turbine for shell Different requirements such as the flow area of each node of the body, the angle of the guide vane, the diameter of the runner, and the shape of the blade, so as to meet the user's process and use requirements realistically.
