Description

Technical Field

[0001] The invention belongs to the field of natural ventilation indirect air cooling towers in thermal / nuclear power plants, and in particular relates to a cooling triangle unit with a multi-layer laterally adjustable flow balancing device group. Background Art

[0002] The natural ventilation direct air cooling system or the natural ventilation indirect air cooling system cools the circulating water through the ambient wind. The cooling performance of the natural ventilation air cooling system is easily affected by the ambient wind. The stability and uniformity of the internal air volume of the cooling triangle unit as the core component of the air cooling system are important factors that determine the heat exchange performance of the cooling triangle unit. Under normal circumstances, the ambient wind is distributed in a power function. The ambient wind speed on the upper side of the cooling triangle is large, and the wind speed on the lower side is small, which easily leads to uneven distribution of the ambient wind entering the tower. The wind speed on the upper side of the cooling triangle is large. When the ambient wind enters the cooling triangle unit, the ambient wind directly acts on the flow equalizing device, increasing the ventilation resistance inside the cooling triangle.

[0003] China's authorized patent, patent number ZL 2015 1 0055635.6, discloses an air-side flow balancing device for the cooling triangle of an intercooler tower, which is composed of at least one group of flow balancing components arranged along the circumference of the intercooler tower, specifically including a cooling triangle, a first flow balancing plate for changing the flow direction of the cooling triangle inlet air is provided in the cooling triangle cavity, the first flow balancing plate is arranged along the middle symmetry plane of the cooling triangle and extends outward to the outside of the cooling triangle; second and third flow balancing plates for gathering and guiding the incoming air are respectively provided on the outer end faces of the cooling columns on both sides of the cooling triangle, the second and third flow balancing plates are respectively extended outward along the radial line of the intercooler tower, and the first, second and third flow balancing plates are all arranged in the vertical direction. The invention reduces the degree of incoming air deviation at the air inlet of the cooling triangle through the mutual cooperation of the three groups of flow balancing plates, eliminates the low-speed vortex area of ​​the air in the cooling triangle, and maximizes the incoming air balancing effect on the cooling triangle. Patent No. 202111545557.X is a cooling triangle unit equipped with a flow equalizing device with a central jet gap, comprising a cooling triangle unit and a flow equalizing device with a central jet gap. On the basis of evenly dividing the cooling triangle inlet air, the jet formed by the central jet gap eliminates the vortex induced by the incoming tower air on the leeward side of the flow equalizing device, thereby improving the cooling columns on the left and right sides of the cooling triangle unit and its overall cooling performance. Patent No. 202111610358.2 is a cooling triangle unit equipped with a flow equalizing device with alternating jet equalization, comprising a cooling triangle unit and a flow equalizing device with alternating jet equalization. On the basis of balancing the incoming air on the left and right sides of the cooling triangle, the multi-stage jet formed by the multi-stage jet gap eliminates the multi-stage vortex formed by the incoming tower air on the leeward side of the flow equalizing device, thereby improving the cooling performance of the cooling columns on the left and right sides. The flow balancing devices of the above-mentioned patents are all fixed flow balancing devices. When the ambient wind obliquely enters the air inlet louvers of the cooling triangle unit, the air vortex induced by the leeward side of the flow balancing device can be eliminated on the basis of balancing or evenly dividing the air inlet on the left and right sides of the cooling triangle. However, when the ambient wind at high wind speed obliquely enters the cooling triangle unit, the flow balancing device has a large resistance effect, which will reduce the cooling performance of the cooling triangle unit. The present invention provides a cooling triangle unit with a multi-layer laterally adjustable flow balancing device group. The ambient wind speed in the upper part along the height direction is large, and the ambient wind speed in the lower part is small. According to the distribution of the ambient wind speed and the inlet angle along the height direction, the expansion degree of each laterally adjustable flow balancing device module roller shutter in each layer of the laterally adjustable flow balancing device group is coupled and regulated to achieve three-dimensional coupling optimization of the internal space flow field of the cooling triangle unit, thereby avoiding the problem of large resistance of the upper flow balancing device group at large ambient wind speed and large inlet angle.
