<p>PROBLEM TO BE SOLVED: To provide a cooling method for waste gas in which dioxins can be prevented from being resynthesized and waste water is not produced without increasing the cost of a device and a running cost. SOLUTION: When the flow rate of waste gas from a waste combustion and treatment device is x m3 (normal state)/hr, the length of a waste gas introducing part is x/3 mm or more, the exhaust speed of waste gas in a cooling tower is 0.2 to 2 m/sec, a retention time of waste gas in the cooling tower is 3 to 20 seconds, the diameter of water droplet of water jetted from a water distributing nozzle is 150μm or smaller and the temperature of a gas exhaust part is 120 to 200 deg.C.</p> |
