Abstract

The invention discloses a double-layer wet-cooling tower with partitioning walls. The double-layer wet-cooling tower comprises an inner-layer tower drum and an outer-layer tower drum, wherein the inner-layer tower drum and the outer-layer tower drum are coaxial, the inner parts and the outer parts of the inner-layer tower drum and the outer-layer tower drum are embedded and the bottoms of the inner-layer tower drum and the outer-layer tower drum are level; the bottoms of the inner-layer tower drum and the outer-layer tower drum are respectively fixed on a same mechanical frame; the outer-layer tower drum is a double-curve type cooling tower; the inner-layer tower drum is a cylindrical cooling tower and is higher than the outer-layer tower drum; the lower side of the area between the outer-layer tower drum and the inner-layer tower drum is provided with a filler area and a rain area which are ring-shaped; and the rain area is arranged under the filler area; the partitioning walls are distributed between the inner-layer tower drum and the outer-layer tower drum. The double-layer wet-cooling tower disclosed by the invention has the beneficial effects that since part of fresh air is directly introduced to the central area of the ring-shaped cooling tower, so that the cooling efficiency can be greatly improved; the influence of side wind on the working performance of the wet-cooling tower can be effectively prevented; under the condition of extremely-cold weather, heat load of the filler area in each sector-shaped ring can be maintained to be above critical icing heat load, so that fillers are prevented from being frozen, and the replacement and the maintenance of the fillers of the cooling tower without stoppage can be realized.

Description

technical field [0001] The invention relates to the field of energy and power engineering, in particular to a double-layer wet-cooling tower with a partition wall used in a large-scale thermal power plant. Background technique [0002] On September 12, 2014, the National Development and Reform Commission issued a notice on the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)", which clearly stipulates the power supply that must be achieved by various coal power units in 2020. Coal consumption indicators, coal power units are under great pressure to save energy. [0003] At present, the natural circulation wet cooling towers used in thermal power plants and nuclear power plants are used, and the bottom is naturally ventilated. Circulating water enters the filling layer of the cooling tower and flows downward, and air flows upward from the air inlet at the bottom to absorb the heat of circulating water, complete the p...
