Embodiment 1

[0024] Such as figure 1 The thermodynamic cooling power generation tower shown has a thermodynamic fan and a vertical fan blade power generation system; the thermodynamic fan consists of an air duct, and a heat medium collection system and a heat medium distribution system arranged in sequence according to the flow direction of the heat medium inside the duct. Tubes and heat exchange core tubes.

[0025] The thermal fan self-suctions a huge amount of air to cool the heat medium in the heat exchange core tube. The heat medium is a high-temperature liquid at the bottom of the distillation tower; the airflow sucked by the thermal fan performs heat exchange with the heat medium in the heat exchange core tube After being heated, it becomes low-density hot air. Under the action of the "chimney effect" of the air duct, a rising hot air flow with a basically constant speed is formed and blown out from the top of the air duct.

[0026] In actual application, the circulating cooling wa...

Embodiment 2

[0028] The return water (heat medium) flow rate of the circulating cooling water in Example 1 is 116m3 / h, the return water pressure is 0.22MPa, and the temperature is 44°C. MPa. The exhaust air velocity at the top of the air duct is 2.2m / s, the exhaust air temperature is 40°C, the rotation speed of the vertical power generation fan blade is 72rpm, and the total power generation is 65kw.

Abstract

The invention provides a thermodynamic cooling power tower. The thermodynamic cooling power tower is provided with a thermodynamic draught fan and a vertical fan blade power generation system, whereinthe thermodynamic draught fan is composed of a wind cylinder, and a return water inlet, a heating medium distribution tube, a heat exchange core tube, a heating medium collection system and a water outlet, which are sequentially arranged in the wind cylinder along the flowing direction of a heating medium, the heating medium collection system is composed of a liquid collection tube, a collectionpump, a pump outlet pipeline and the like, and a heat compensation system can possibly be arranged between the liquid collection tube and the collection pump. Closed circulation of the thermodynamic cooling power tower can reduce power consumption of a circulating cooling water conveying device, converts potential waste heat into electric energy, and applies the electric energy in a production line of an enterprise of the applicant, and simultaneously water vapor is prevented from excessively evaporating, and after popularization and application, the thermodynamic cooling power tower is expected to save a large amount of water source every year, and greatly reduces power consumption.

Description

technical field [0001] The invention relates to a waste heat power generation device. Background technique [0002] The temperature of the return water formed by cooling the superheated medium in industry is relatively high, and the latent heat contained in it needs to be fully utilized to achieve the effect of saving energy and reducing consumption. [0003] The patent application number is 2015101122227, a power generation device for cooling towers and its control method, belonging to the mechanical field. In order to solve the two problems in the prior art that the kinetic energy of the gas discharged from the gas outlet cannot be fully utilized and the voltage and current of the electric energy generated by the generator are stable and unstable, the present invention provides a power generation system that utilizes the rising hot air flow in the cooling tower to generate electricity. Device and control method thereof. It consists of a cooling tower, a guide rod fixed o...
