When the temperature in the combustion chamber reaches At 700-850°C, open the valve at the exhaust port 11, turn on the induced draft fan, let the hot air pass through the exhaust pipe 12 to heat the activated carbon adsorption chamber 2, open the valve on the air pipe 14, and let the outside air enter the flue 13, the hot air in the flue 13 is cooled and discharged through the induced draft fan;
(2)当活性炭吸附室2内的温度达到400-500℃时，关闭引风机，关闭排气口11处的阀门，并打开通气孔4处的阀门，使活性炭吸附室2内活性炭吸附床9挥发出的有害气体通过通气孔4进入燃烧室3内，然后在燃烧器10的作用下燃烧；(2) When the temperature in the activated carbon adsorption chamber 2 reaches 400-500°C, close the induced draft fan, close the valve at the exhaust port 11, and open the valve at the air hole 4, so that the activated carbon adsorption bed 9 in the activated carbon adsorption chamber 2 The volatilized harmful gas enters the combustion chamber 3 through the vent hole 4, and then burns under the action of the burner 10;
(3)打开引风机和排气口11处的阀门，使燃烧室3内燃烧后的气体经排气管12进入烟道13，开启空气管道14上的阀门，使外界空气进入烟道13内，使烟道13内的气体冷却后经引风机排出；(3) Open the valve at the induced draft fan and the exhaust port 11, so that the gas after combustion in the combustion chamber 3 enters the flue 13 through the exhaust pipe 12, and open the valve on the air pipe 14, so that the outside air enters the flue 13 , so that the gas in the flue 13 is cooled and discharged through the induced draft fan;
(4)关闭燃烧器10，打开燃烧室3上的空气进口15，使外界空气进入燃烧室，并进入排气管12，对燃烧室和活性炭吸附室2进行冷却，空气通过烟道13最后经引风机排出，当燃烧室和活性炭吸附室2冷却到室温时，即可再次进行废气处理过程。(4) Close the burner 10, open the air inlet 15 on the combustion chamber 3, make the outside air enter the combustion chamber, and enter the exhaust pipe 12, the combustion chamber and the activated carbon adsorption chamber 2 are cooled, and the air passes through the flue 13 and finally passes through the exhaust pipe 12. The induced draft fan discharges, and when the combustion chamber and the activated carbon adsorption chamber 2 cool down to room temperature, the waste gas treatment process can be carried out again.
