The function of the quenching tower is to quickly cool down the flue gas. The temperature of the flue gas coming out of the boiler is around 550°C. In order to avoid the regeneration of dioxin substances in the temperature range of 250°C to 400°C, the system must shorten the short residence time of the flue gas at this temperature as much as possible, so the system is set up with rapid cooling The spray tower is used to quickly cool down the flue gas. During the mixing and falling process of the water mist and flue gas, gasification is completed, and no sewage will be generated at the bottom.
The quench tower adopts the direct cooling method of spraying tap water. The flue gas flowing through the tower directly contacts the atomized liquid. The injected liquid quickly vaporizes and takes away a large amount of heat, and the flue gas temperature can be quickly reduced to 180°C. °C to avoid the regeneration of dioxins. The quenching tower can control the temperature of the flue gas entering the dust collector, and ensure the inlet temperature of the bag dust collector by controlling the amount of liquid spray to prevent the flue gas temperature from being too high and affecting the operation of the bag dust collector.
