Working condition without fog dispersal
As shown in fig. 1, in this mode of operation, the regulating valve of the middle nozzle is opened, the air adjusting device on the side surface of the cooling tower is closed, the air adjusting device above the middle filler is opened, the cold channel of the defogging module does not work, and the hot channel realizes the function of the filler. The open arrows indicate the ambient air flow, and the arrows with cross-hatching inside the slashes indicate the saturated hot and humid air flow.
Semi-fog dispersal regime
As shown in fig. 2, under this condition, the regulating valve of the middle nozzle is opened, the air adjusting devices on the two side panels of the cooling tower are opened, and the air adjusting device above the middle filler is opened. And ambient dry and cold air enters the cold channel of the fog dissipation module from the side surface of the cooling tower under the action of the fan and performs recuperative heat exchange with saturated wet air and hot water in the hot channel.
