A regenerative cooling tower and its operation control method

Abstract

The invention relates to a heat accumulating type cooling tower and an operational control method thereof. Heat accumulating type direct-heat-transfer type heat exchanging is adopted, water gasification does not exist, water evaporation loss is reduced, a circulating water system can be closed, a cooling air inlet can be used for filtering, intrusion of fine dust in the air is reduced, the cooling efficiency of circulating water can be effectively improved, equipment abrasion can be reduced, and the blowdown capacity can be decreased; breeding of bacteria and alga in the circulating water can be effectively reduced, chemical reagents for treating the bacteria and the alga can be saved, consumption is reduced, and pollution is removed; and the water surface evaporative water consumption of a circulating water pool (tank) can be effectively reduced, and the transverse evaporative water consumption, caused by atmospheric motion, of an air duct of the cooling tower can be effectively eliminated.

Description

technical field [0001] The invention relates to a regenerative cooling tower, especially a single-tower multi-group regenerative cycle switching operation and direct heat exchange cooling tower, which is widely used in various industries such as electric power, petroleum, chemical industry, steel, and civil use, and belongs to Water saving technology field. Background technique [0002] The cooling water tower is basically an open type. The cooling water tower is also called a cooling water tower. The principle of the cooling water tower is to atomize the water into tiny water droplets and contact the air. The waste heat in the circulating water is dissipated, and the dry and low-enthalpy air can also be used in the form of a high tower after being pumped by the fan. Using the chimney effect, it enters the cooling tower from the air inlet, and the humid and high-enthalpy water self-spreads the water system Sprinkled into the tower, when the water droplets are in contact wit...

AI Technical Summary

Problems solved by technology

[0005] With the seriousness of air pollution, the acidic and harmful substances in the atmosphere also undergo mass transfer during the atomization heat transfer process of water, so that the acidic gases in the atmosphere dissolve into the water, which increases the corrosiveness of the circulating water and causes pipe failure. Corrosion of road systems and cooling equipment

[0006] In short, the current method of evaporative cooling of circulating water with latent heat of vaporization and cooling towers not only cause waste of water resources, but also cause many problems in the structure of circulating water, corrosion, and the growth of bacteria and algae
