Description

Technical Field

[0001] This invention relates to the field of industrial cooling circulating water utilization, and more particularly to a method for generating electricity using industrial cooling circulating water. Background Technology

[0002] Industrial cooling circulating water uses water as a cooling medium to exchange heat and cool equipment in industrial production. To avoid wasting water resources, the cooling water is cooled and then recycled. The applicant discovered that cooling circulating water generates a large amount of energy during use, and that utilizing it could yield greater benefits. Therefore, the applicant has conducted further research and development on this technology. Summary of the Invention

[0003] In view of the above technical problems, the present invention provides a method for generating electricity using industrial cooling circulating water, characterized in that an eddy current generator is added in the industrial cooling circulating water circulation equipment, and the circulating water is used to flush the eddy current generator, thereby effectively utilizing the flow rate and volume of the circulating water to convert kinetic energy into electrical energy.

[0004] The circulating water power generation equipment comprises a circulating water tank, an eddy current generator, a battery control cabinet, a PLC control cabinet, an inverter control cabinet, a level gauge, electric valves, a flow meter, a heat exchanger, a circulating water pump, a cooling tower, and pipelines. The circulating water tank and the circulating water pump are connected. The circulating water pump is connected to the heat exchanger via pipelines. The heat exchanger is connected to the cooling tower via pipelines. The cooling tower is installed above the circulating water tank. A level gauge is installed inside the circulating water tank. An eddy current generator is installed inside the circulating water tank. The eddy current generator is connected to the battery control cabinet, the PLC control cabinet, and the inverter control cabinet, respectively.

[0005] A water channel is provided in front of the circulating water pump, and an eddy current generator is installed inside the water channel. The water channel is connected to the circulating water pump and has a funnel-shaped structure.

[0006] The circulating water tank consists of a high-level circulating water tank and a low-level circulating water tank, which are connected by a pipeline. Electric valves, flow meters, and multiple eddy current generators are sequentially installed on this pipeline. A high-level level gauge is installed in the high-level circulating water tank, and a low-level level gauge is installed in the low-level circulating water tank. The electric valves, flow meters, high-level level gauges, and low-level level gauges are each connected to a PLC control cabinet. The PLC control cabinet controls the electric valves to adjust the flow rate through the pipeline based on the detected flow rate. N eddy current generators are connected to corresponding batteries in a battery control cabinet, which is then connected to an inverter.

[0007] There are N pipes, and the number of pipes installed is determined by the length and width of the high-level circulating water tank and the low-level circulating water tank, as well as the circulating water volume.

[0008] The eddy current generator is connected to the battery in the battery control cabinet. The battery is connected to the inverter in the inverter control cabinet to convert DC power into AC power. The inverter controller then sends the AC power into the power grid.

[0009] The electric valves, flow meters, and multiple eddy current generators are sequentially installed on the pipeline connecting the high-level circulating water tank to the low-level circulating water tank. The high-level level gauge is installed in the high-level circulating water tank to detect its level, and the low-level level gauge is installed in the low-level circulating water tank to detect its level. The electric valves, flow meters, high-level level gauges, and low-level level gauges are connected to a PLC control cabinet. The PLC control cabinet controls the electric valves based on the detected flow rate to adjust the flow velocity through the pipeline, stabilizing the flow velocity of the eddy current generators to prevent excessively high flow rates from burning out the motors and excessively low flow rates from failing to drive the turbine fans. The N eddy current generators are connected to corresponding batteries in a battery control cabinet, which is then connected to an inverter. The original circulating water tank is designed as a high-level and low-level circulating water tank to create a difference in water level.

[0010] When the liquid level in the high-level circulating water tank reaches the upper limit, the PLC control cabinet adjusts the number of vortex pipes by controlling the electric valve switch installed on the vortex pipe.

[0011] When the liquid level in the low-level circulating water tank reaches the upper limit, the PLC control cabinet controls the electric valve installed on the vortex pipe to adjust the number of vortex pipes.

[0012] The vortex pipe is equipped with an electric valve and a flow meter, which are connected to a PLC control cabinet. The PLC control cabinet controls the opening of the electric valve based on the detected flow rate to adjust the flow velocity through the vortex pipe. This controls the flow velocity of the circulating water through the vortex generator, preventing the motor from burning out due to excessive flow velocity or the generator from failing to generate electricity due to insufficient flow velocity.

[0013] N eddy current generators are installed in series on the eddy current pipe. The number of eddy current generators is determined by the height difference between the high-level and low-level circulating water tanks. This effectively utilizes the flow rate and velocity of the circulating water to convert kinetic energy into more electrical energy.

[0014] The number of vortex pipes installed is determined by the length and width of the high-level circulating water tank and the low-level circulating water tank, as well as the circulating water volume.

[0015] The eddy current generator is connected to the battery in the battery control cabinet. The battery is then connected to the inverter in the inverter control cabinet, converting DC power to AC power. The inverter controller then feeds the AC power into the power grid.

[0016] The eddy current generator is equipped with encoders, which are connected to the PLC control cabinet to detect the rotational speed of the eddy current generator. When the rotational speed of the eddy current generator is too high or too low, the electric valve installed on the pipeline can be adjusted by the PLC to control the flow rate through the eddy current generator and prevent damage to the eddy current generator.

[0017] The beneficial effects of this invention are as follows: This invention utilizes a series of structural designs and a cooling water circulation process to generate electricity from industrial cooling circulating water, thus saving resources. This invention utilizes the height difference between the high-level circulating water pool and the low-level circulating water pool, thereby generating eddies as the circulating water passes through electric valves, flow meters, eddy current generators, etc. installed on the pipeline, thereby driving the eddy current generator to generate electricity.

[0018] This invention has two applications. One is to place the eddy current generator in the water channel in front of the pump in the circulating water tank, and then use the suction action of the circulating pump to drive the eddy current generator to generate electricity. The other is to design the circulating water tank as a high-level water tank and a low-level water tank to create a height difference, and the circulating water flow drives the eddy current generator to generate electricity.

The circulating water tank and the circulating water pump are connected. The circulating water pump is connected to the heat exchanger via pipelines. The heat exchanger is connected to the cooling tower via pipelines. The cooling tower is installed above the circulating water tank. A level gauge is installed inside the circulating water tank. The eddy current generator is installed inside the circulating water tank and is connected to the battery control cabinet, the PLC control cabinet, and the inverter control cabinet. A water channel is provided in front of the circulating water pump, and the eddy current generator is installed inside the water channel. The water channel is connected to the circulating water pump.

[0026] The circulating water tank consists of a high-level circulating water tank and a low-level circulating water tank, which are connected by pipes. Electric valves, flow meters, and N eddy current generators are sequentially installed on these pipes. A high-level level gauge is installed in the high-level circulating water tank, and a low-level level gauge is installed in the low-level circulating water tank. The electric valves, flow meters, high-level level gauges, and low-level level gauges are all connected to a PLC control cabinet. The PLC control cabinet controls the electric valves to regulate the flow rate through the pipes based on the detected flow rate. The N eddy current generators are connected to corresponding batteries in a battery control cabinet, which is connected to an inverter. The number of pipes (N) is determined by the length and width of the high-level and low-level circulating water tanks, as well as the circulating water volume.

[0027] The eddy current generator is connected to the battery in the battery control cabinet. The battery is connected to the inverter in the inverter control cabinet to convert DC power into AC power. The inverter controller then sends the AC power into the power grid.

[0028] Example 2

[0029] The circulating water system is designed with a high-level circulating water tank and a low-level circulating water tank, with circulating water flowing from the high-level tank to the low-level tank. During operation, the circulating water is pumped into a cooling tower, cooled, and then returns to the high-level circulating water tank. The high-level and low-level circulating water tanks are connected by a pipeline with a height difference. Eddy current generators are installed on the pipeline. The vertical number of eddy current generators is determined by the height difference between the high and low-level circulating water tanks. The horizontal number of eddy current generators is determined by the length and width of the high and low-level circulating water tanks. Flow meters and electric valves are also installed on the pipeline. The flow rate detected by the flow meters is fed back to the PLC control cabinet, which controls the opening of the electric valves to regulate the flow rate through the eddy current pipeline, protecting the eddy current generators from damage due to excessive flow velocity. A level gauge is installed in the high-level circulating water tank and is connected to the PLC control cabinet. When the liquid level is too high or too low, the PLC control cabinet can adjust the liquid level in the high-level circulating water tank by controlling the number of eddy current generators horizontally. The low-level circulating water tank is equipped with a level gauge; when the liquid level in the low-level circulating water tank is too high or too low, the PLC control cabinet can also adjust the liquid level in the low-level circulating water tank by controlling the number of eddy current generators horizontally. Each eddy current generator is equipped with an encoder, which is connected to the PLC control cabinet to detect the rotational speed of the eddy current generator. When the rotational speed of the eddy current generator is too high or too low, the electric valve installed on the pipeline can be adjusted through the PLC control cabinet to control the flow rate through the eddy current generator and prevent damage to the generator. The eddy current generator is connected to a battery via wires to store electricity, which is then inverted into AC power by an inverter and fed into the power grid.

[0030] Example 3

[0031] The industrial cooling circulating water system of this invention features a pre-pump water channel. During use, the eddy current generator is immersed in the channel, and the number of eddy current generators is determined by the size of the pre-pump water channel. The inlet of the eddy current generator is designed as a funnel to increase the flow velocity. The size of the funnel determines the rotational speed generated when the flow passes through the eddy current generator. An encoder on the eddy current generator is connected to a PLC to measure the actual rotational speed of the eddy current generator. The eddy current generator is connected to a battery via wires for energy storage, and the battery is then connected to an inverter to convert the energy into alternating current for power grid connection.
