A high-efficiency heat-exchanging, water-saving, demisting wet cooling tower

Abstract

The invention discloses an efficient heat-exchanging, water-saving and mist-removing cooling tower, and relates to an automatic high-speed rotating spraying device with a fan blade and a device for restoring water mist of a cooling tower outlet to cooling water for recycling use. The efficient heat-exchanging, water-saving and mist-removing cooling tower comprises four main parts: an automatic high-speed rotating atomizing sprayer with the fan blade, a waterfall type water collector, a hook baffle plate mist remover, a pressurized pump and a related pipeline. The automatic high-speed rotating atomizing sprayer converts kinetic energy of fluid into surface energy to promote water flow atomization, and therefore the atomization performance of water spraying of the sprayer is strengthened, the heat exchanging efficiency between water droplets and air is enhanced, and the fan blade is installed on a center nozzle to makes the efficiency further improved. Water saving and mist removing are divided into two stages: in the first stage, when wet air goes through the waterfall type water collector, a part of water vapor is liquefied and falls with the waterfall, a part of the water vapor gets larger in diameter and goes into the hook baffle plate mist remover with the air, and the water vapor in the wet air is glued to the blade and breaks away from the air, and eventually is collected in a liquid form to a water reservoir at the bottom of the cooling tower. Therefore, the heat-exchanging efficiency of the cooling tower is improved effectively, and the water mist in the air exhausted from the cooling tower outlet is effectively reduced, and the cooling tower is beneficial for water saving and environmental protection.

Description

technical field [0001] The invention relates to a high-efficiency heat-exchange, water-saving, water-saving and demisting wet cooling tower, which is used for reducing the moisture content of outlet air and enhancing the heat and mass exchange efficiency between cooling water and air in the tower, and belongs to the technical field of industrial circulating water cooling. Background technique [0002] The function of the cooling tower is to exchange heat or heat mass between the circulating water carrying waste heat and the air in the tower, transfer the heat of the water to the air and disperse it into the atmosphere, and cool down the circulating water. Cooling towers are divided into wet cooling towers (heat and mass exchange) and dry cooling towers (heat exchange) according to the different contact methods between circulating water and air. [0003] In the wet cooling tower, the circulating water sprayed on the surface of the filler is in direct contact with the air, thr...

Problems solved by technology

However, although the nozzles used in the existing spray devices increase the heat exchange efficiency to a certain extent, in large-scale industrial production, the volume of the cooling tower is usually relatively large. In order to ensure that the water droplets fully contact with the air, it is necessary to increase the number of nozzles to increase The large spray area leads to the complexity of the corresponding water distribution pipelines. When the small droplets encounter the pipelines when they fall, they will condense on the outer surface of the pipelines, forming a small water flow and then falling down. This will reduce the contact area between water and air. Reduced cooling effect
