Abstract

The invention discloses a cooling triangular unit of a flow-equalizing shutter with vertically rotatable shutters, which comprises a cooling triangular unit and a flow-equalizing shutter with vertically rotatable shutters, and the cooling triangular unit comprises a left side cooling column, a right side cooling column and an air inlet shutter, the flow-equalizing louver with the vertically-rotatable shutters comprises a louver fixing device, the vertically-rotatable shutters and an executing mechanism, and the flow-equalizing louver with the vertically-rotatable shutters is vertically arranged along the vertical central symmetry plane of the cooling triangular unit. A cooling triangle unit of a flow-equalizing louver with louver blades capable of rotating vertically can regulate and control the louver according to environmental wind speed and wind direction: when the environmental wind speed is small, the louver is set to be in a closed state to play a role in cooling triangle air side flow equalizing; when the environment wind speed is large and certain air inlet deviation exists, the louver is opened by a certain angle, the ventilation resistance in the cooling triangular unit is reduced, environment wind distribution in the cooling triangular unit is optimized, and the heat exchange performance of the cooling triangular unit is improved.

Description

technical field [0001] The invention belongs to the field of indirect air-cooling towers of thermal power plants, and particularly relates to a cooling triangular unit with an equalizing louver with louvers that can be rotated vertically. Background technique [0002] The indirect air cooling tower relies on the ambient air to cool the circulating water, so the cooling performance of the indirect air cooling system is easily affected by the ambient air. The cooling triangle unit is the core component of the indirect air cooling system. The overall ventilation resistance of the cooling triangle determines the overall cooling performance of the cooling columns on both sides of the cooling triangle unit. In the natural environment, the cooling columns on the left and right sides of the cooling triangle unit are prone to the phenomenon of uneven air intake and large deviation of cooling performance. Air intake from side cooling columns optimizes the overall cooling performance ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the internal ventilation resistance of the cooling triangular unit increases due to the large ambient wind speed and a certain air intake deviation angle after the installation of a flow equalizer in the cooling triangular unit. The cooling triangular unit of the vertically rotating flow equalizing louver can be adjusted freely according to the ambient wind speed and the air intake deviation angle of the cooling triangular unit, and the vertically rotating louver type flow equalizing device can be adjusted to the closed state when the ambient wind speed is small , which plays the role of cooling the triangular air side flow; when the wind speed in the environment is large and the air intake deviation angle is small, the louvers can be adjusted to open a certain angle, which can not only reduce the ventilation resistance of the cooling triangular unit, but also cool the triangular air side The function of flow equalization; when the ambient wind speed is large and the air intake deviation angle is large, the louvers can be adjusted to the fully open state to reduce the internal ventilation resistance of the cooling triangular unit, reduce the adverse effects of the flow equalization device, and optimize the internal environment of the cooling triangular unit Wind distribution to improve the heat transfer performance of the cooling delta unit
