Cooling tower water return power generation device and power generation method by using same

Abstract

The invention discloses a cooling tower water return power generation device. The cooling tower water return power generation device comprises a cooling tower, a water collecting pool and a water return pool, wherein the water collecting pool is communicated with the water return pool through a water return pipe; and hot returned water is conveyed to the cooling tower through a hot water pipe. The cooling tower water return power generation device further comprises a power generation component and a liquid level control device; the liquid level control device comprises a liquid level meter, a water replenishing control switch, an electric valve and a water replenishing pipe; one end of the water replenishing pipe is communicated with the water return pool, and the other end is communicated with an external water source through an electric valve; the liquid level meter is mounted in the water return pool, and is connected with the water replenishing control switch through a cable; and the water replenishing control switch is connected with the electric valve through a cable. A power generation method of the cooling tower water return power generation device comprises the steps of: (A) installation of the power generation component and the liquid level control device; (B) starting of the power generation; (C) water replenishment; and (D) overflowing. The cooling tower water return power generation device is simple in structure, can modify a traditional pipeline without changing traditional technological flows, and can fully use traditionally wasted potential energy to greatly improve the self power generation rate of enterprises so as to achieve the effects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a power generation device and a power generation method, in particular to a cooling tower return water power generation device and a method for using the cooling tower return water potential energy to generate electricity in a circulating water cooling tower cooling system. Background technique [0002] Currently, if figure 1 As shown, in the known industrial circulating water cooling tower heat dissipation system, the return hot water from the process equipment passes through the self-flow or lift pump, hits the cooling tower, and falls to the sump after cooling down through the cooling tower, and then the water from the sump It falls back to the pool through the return pipe for recirculation. [0003] In the above process, the problem is that the cooling tower sump located on the roof of the water pump often has a height difference of 8-12 meters from the pool on the ground, and the flow rate of industrial circulating water ...

Problems solved by technology

[0003] In the above process, the problem is that the cooling tower sump located on the roof of the water pump often has a height difference of 8-12 meters from the pool on the ground, and the flow rate of industrial circulating water is more than a thousand cubic meters per second. The circulating water falls directly from the sump to the pool, and the potential energy of this part of the water is wasted and cannot be used effectively
