Cooling triangular unit provided with flow equalizing device with middle jet flow gap

Abstract

The invention discloses a cooling triangle unit provided with a flow equalizing device with a middle jet gap, which comprises a cooling triangle unit and a flow equalizing device with a middle jet gap, and the cooling triangle unit comprises a left side cooling column, a right side cooling column and an air inlet shutter, the flow equalizing device with the middle jet flow gap comprises an outer flow equalizing plate, an inner flow equalizing plate and the middle jet flow gap, the outer flow equalizing plate extends inwards by a certain distance Lw from the air inlet louver along the vertical central symmetry face of the cooling triangle, and the inner flow equalizing plate extends inwards by a certain distance Ln from the position with the distance Lj from the inner end of the outer flow equalizing plate along the vertical central symmetry face of the cooling triangle. The inner end of the outer side flow equalizing plate and the outer end of the inner side flow equalizing plate form a jet flow gap. Based on the middle jet flow gap, on the basis of equally dividing the inlet air of the cooling triangle, vortex induced by air entering the tower on the leeward side of the flow equalizing device is eliminated through jet flow formed by the middle jet flow gap, and then the cooling performance of the cooling columns on the left side and the right side of the cooling triangle unit and the overall cooling performance are improved.

Description

Technical field [0001] The present invention belongs to the indirect air-free field of fire / nuclear power plants, and in particular, the present invention relates to a cooling triangulation unit for mounting a current-band jet. Background technique [0002] The air-cooled technology has been widely used in the fire power plant in the north "rich coal shortage" area in the north, indirect air-cooling system adopts natural ventilation, with low operation back pressure, low power supply, and power plant operation. Economic good characteristics, but indirect air-cooling systems, the cooling limit of circulating water is a dry ball temperature of the ambient air, which causes the vectors back pressure to be influenced by the external environment, and the atmospheric pressure and changes in the atmospheric pressure and dry ball temperature in environmental parameters. The selection and operation of the cooling tower is smaller, and the wind speed, and the changes in humidity have a g...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the phenomenon that the air entering the tower easily forms a vortex on the leeward side of the flow equalization device of the cooling triangular unit under the condition of side wind, which further leads to the problem that the cooling capacity of the cooling columns on the left and right sides of the cooling triangular unit decreases. The present invention provides A cooling triangular unit equipped with a flow equalization device with a jet in the middle. Based on the flow equalization device with a jet in the middle, on the basis of the uniform distribution of the air intake of the cooling triangular unit, the jet formed by the jet gap in the middle eliminates the air entering the tower The eddy current induced on the leeward side of the flow equalizer improves the cooling columns on the left and right sides of the cooling triangular unit and its overall cooling performance
