White smoke and power reduction high-efficiency counter flow cooling tower and control method thereof

Abstract

The present invention relates to a high efficiency cooling tower for reducing white lead and power consumption and a control method for the same. The present invention comprises a dry heat exchange part which is partitioned into an upper dry heat exchange part (40a), and a lower dry heat exchange part (40b) stepped down from the upper dry heat exchange part (40a) for a predetermined level; an exhaust bypass flow channel (16); a bypassing exhaust opening and closing part; and a control part (100). Therefore, the present invention improves heat exchange efficiency by enlarging a heat exchange area without an increase in exhaust flow resistance of the dry heat exchange part for reducing white lead by heating saturated humid air exhaust; and effectively controls a wet cooling operation, a white lead reducing operation, a dry cooling operation, and a cooled high temperature fluid bypass flow operation.

Description

technical field [0001] The invention relates to a counter-flow cooling tower for reducing white smoke, in particular, a high-efficiency counter-flow cooling tower for reducing white smoke and power and its control method, which can reduce white smoke by heating the exhaust of saturated humid air without increasing dry heat The exhaust flow resistance of the exchange part expands the heat exchange area, thereby improving the heat exchange capacity; during wet cooling operation, the high-temperature fluid flowing in the dry heat exchange part is detoured and flowed to the sprinkling part, so that the exhaust gas that passes through the dry heat exchange part While the flow resistance of the high-temperature fluid is generated, the power consumption of the high-temperature fluid pump is reduced; during wet cooling operation, a considerable amount of non-resistance exhaust gas passing through the dry heat exchange part is detoured to the exhaust port to reduce exhaust gas At the s...

AI Technical Summary

Problems solved by technology

[0042] Next, the problem of the white smoke reduction cooling tower 2b of the prior art 2 is the same as that of the white smoke reduction cooling tower 2a of the prior art 1, and the high temperature fluid can be used without the atmospheric conditions of the white smoke reduction operation or wet cooling operation or low temperature atmospheric conditions. The dry heat exchange part 40c that normally flows to the heat exchanger for white smoke reduction operation generates unnecessary high-temperature fluid flow resistance, thereby wasting the power consumption of the high-temperature fluid pump, and the power consumption of the high-temperature fluid pump is reduced during wet cooling operation and dry cooling operation. Under any operation, the exhaust gas can normally flow to the dry heat exchange part 40c, resulting in unnecessary flow resistance of the exhaust gas and increasing the power consumption of the blower
