Cooling water waste heat power generation device

Abstract

The invention discloses a cooling water waste heat power generation device, has an obvious water-saving effect and high thermal energy conversion efficiency, has no secondary energy consumption, has no noise pollution in operation, has a long service life and few maintenance components, and has a simple structure, mainly consisting of radiating water pipes (1), power generation modules (2), radiating fins (3), a radiating air duct (5) and a mounting bracket (6). The mounting bracket (6) is installed on the floor, a middle part and an upper part are equipped with the radiating water pipes (1), the top is connected with the radiating air duct, outer surfaces of the radiating water pipes (1) are equipped with the power generation modules (2), and the radiating fins (3) are vertically mounted outside the power generation modules (2); and the cooling water waste heat power generation device can be widely applied to waste heat utilization of process cooling water of enterprises of iron and steel, the chemical industry, papermaking, power plants and the like, and is used in place of an existing cooling tower.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of residual energy and water saving, and relates to a waste heat power generation device, in particular to a cooling water waste heat power generation device. Background technique [0002] In the production of industrial enterprises, especially in the production of steel and chemical enterprises, circulating water is required for cooling in the production equipment and product process. The residual heat in the circulating cooling water is very huge, but because the grade of this part of the heat source is relatively low, except A very small part is used as heating in winter in the northern region, and the rest are cooled by cooling towers. However, for cooling towers, the heat flow out of the tower carries a large amount of heat and tiny water droplets into the atmosphere, and the heat emission is likely to cause thermal pollution in the surrounding area. About 1%, after evaporative cooli...

Problems solved by technology

However, for cooling towers, the heat flow out of the tower carries a large amount of heat and tiny water droplets into the atmosphere, and the heat emission is likely to cause thermal pollution in the surrounding area. About 1%, after evaporative cooling, it will also lead to a decline in water quality

Although the heat pump technology is relatively mature at present, because the compressor of the heat pump is mostly driven by electric energy or fuel combustion, electric energy and fuel are high-grade energy, and high-grade energy is consumed to obtain the utilization of waste heat energy, which is directly restricted by uneconomical operating costs. to promote
