A power generation device for a cooling tower and its control method

Abstract

The invention discloses a power generating device for a cooling tower and a control method thereof and belongs to the field of machinery. The power generating device for generating power through rising hot air in the cooling tower and the control method thereof are used for solving the two problems that in the prior art, the kinetic energy of gas exhausted out of a gas outlet cannot be fully used for generating power and the voltage and current of the electric energy generated by a generator are unstable. The power generating device is composed of the cooling tower, a guide rod fixed to the top of the cooling tower, a sliding block arranged on the cooling tower through a hydraulic cylinder, a sleeve arranged on the sliding block and a wind driven generator arranged at an outlet in one end of the sleeve. According to the power generating device for the cooling tower and the control method thereof, energy-saving improvement can be conducted on an old tower, and the power generating device can be used in cooperation with a newly-built tower; the larger the tower is, the more obvious the energy saving effect is; the voltage and the current of the electric energy generated by the generator are stable, and the trouble caused by follow-up utilization of the electric energy is greatly reduced.

Description

[0001] Field [0002] The invention belongs to the field of machinery, and in particular relates to a power generation device for a cooling tower and a control method thereof. Background technique [0003] At present, a large number of cooling towers are used in industries such as metallurgy, chemical industry, pharmacy and building materials. Cooling towers have strong hot air discharge during work, resulting in waste of energy. In order to reduce waste, a power generation device is added on the cooling tower. For example, the existing transformation method is simply to add a fan-driven generator above the air outlet of the cooling tower, which has a certain effect on solving the problem of energy waste. The gas has strong fluidity and will bypass obstacles when encountering obstacles. When the gas discharged from the gas outlet encounters the fan, some of the gas will escape around the fan, and the generator cannot fully utilize the kinetic energy of the gas discharged from ...
