Problems solved by technology

The fog elimination effect of its application is still not complete, the water saving rate is low, and it is only suitable for the construction of new towers. The total height of the tower body is greatly increased, and the energy consumption is greatly increased.

Embodiment 1

[0021] For the entire tower group with multiple towers, when winter comes, the winter operation mode will be gradually turned on. When opening each tower, adjust the water distribution system 4 and the spray system 6, so that the water spraying interval passes through the gap of the packing 7, and the cooling of the spraying water does not directly convect with the dry cold air 10 entering the tower. The water is scattered through the sump pipe 9 and enters the sump 11. The hot water 5 entering the tower is never in contact with the air. The dry cold air 10 entering the tower becomes dry hot air and leaves the outlet 2 of the cooling tower. No production is produced during the cooling process of hot water. Out of Feather Mist1. At the end of winter, the summer mode of some towers in the tower group will be turned on one after another, and as the weather gets warmer and hotter, until all of them return to the summer mode.

Embodiment 2

[0023] For single-room towers, turn on the winter operation mode for some areas inside the tower. In the part of winter mode, adjust the water distribution system 4 and the sprinkler system 6, so that the water spray interval passes through the gap of the packing 7, the cooling of the spray water does not directly convect with the dry cold air 10 entering the tower, and it is at the lower part of the packing 7 or the upper part of the air inlet 8 The water is scattered into the sump 11 through the sump pipe 9, the hot water 5 entering the tower is never in contact with the air, and the dry cold air 10 entering the tower becomes hot and dry air; in the part where the winter mode is not turned on, hot and humid air 3 is still generated. After the air of the two modes is mixed, when leaving the air outlet 2 of the cooling tower, the fog concentration is very low or the plume 1 is not seen. At the end of winter, the summer mode of some parts of the tower will be turned on one afte...

Abstract

The invention discloses a method for completely eliminating cooling tower plume mist, and belongs to the fields of atmospheric environment protection, energy conservation and water conservation. The method comprises: (1) under the conditions that the original structure, the length, the width, the width, the height and the size of a conventional cooling tower are kept, and the original fan configuration is kept, a cooling tower does not generate plume mist in winter through seasonal operation mode conversion; (2) when sprinkling water passes through a filling section, the air and the hot waterpass through own ways, and the rising air does not carry away water; (3) after the sprinkling water passes through the filling section, the sprinkling water continues to transfer heat with the air entering the tower without mass transfer, and water is not evaporated in the heat dissipation process; and (4) the method for eliminating the plume mist is easy to implement and low in investment on a newly-built countercurrent cooling tower and the built conventional cooling tower.

Description

technical field [0001] The invention relates to a method for completely eliminating cooling tower plume and belongs to the fields of atmospheric environment protection and energy and water conservation. Background technique [0002] The design of domestic conventional mechanical ventilation cooling towers follows the GB / T50392 process design specification. The conventional cooling tower process is that the hot water from the heat exchanger of the chemical plant is returned to the water distribution pipeline system on the upper part of the cooling tower with pressure, and then sprayed The splashing system is dispersed into water droplet particles, sprinkled on the top surface of the filler, and forms a water film on the surface of the filler; under the suction of the cooling tower fan, the air enters the tower from the air inlet at the lower part of the cooling tower, and disperses through the gaps on the bottom surface of the filler. Work your way through the filler from the...
