Embodiment 1
[0027] (1) Under the temperature condition of 600°C, mix cyanuric chloride tail gas and methane into the tail gas combustion furnace according to the gas flow ratio of 1:0.05. The cyanuric chloride tail gas and methane come into contact with combustion reaction, and the combustion generates carbon dioxide , nitrogen oxide, water and hydrogen chloride mixed gas, stay in the tail gas combustion furnace for 2 minutes, and enter the next process;
[0028] (2) in Al 2 o 3 loaded TiO 2 -V 2 o 5 -WO 2 Under the action of a catalyst, under the temperature condition of 550°C, the mixed gas obtained in step (1) is passed into the ammonia catalytic furnace, and ammonia gas is passed into the ammonia catalytic reaction at the same time, and the mixed gas and ammonia gas in step (1) are controlled. The flow ratio is 1:0.02; under the action of activated carbon catalyst, the mixed gas reacts with ammonia for 8 minutes, the nitrogen oxide in the mixed gas is transformed into nitrogen, a...
Embodiment 2
[0031] (1) Under the temperature condition of 800°C, the tail gas of cyanuric chloride and methane are passed into the tail gas combustion furnace according to the gas flow ratio of 1:0.2, and the tail gas of cyanuric chloride and methane come into contact with combustion reaction, and the combustion generates carbon dioxide , nitrogen oxide, water and hydrogen chloride mixed gas, stay in the tail gas combustion furnace for 2 minutes, and enter the next process;
[0032] (2) in Al 2 o 3 loaded TiO 2 -V 2 o 5 -WO 2 Under the action of a catalyst, under the temperature condition of 700°C, the mixed gas obtained in step (1) is passed into the ammonia catalytic furnace, and ammonia gas is passed into the ammonia catalytic reaction at the same time, and the mixed gas and ammonia gas in step (1) are controlled. The flow ratio is 1:0.2; under the action of activated carbon catalyst, the mixed gas reacts with ammonia for 8 minutes, the nitrogen oxide in the mixed gas is converted...
Embodiment 3
[0035] (1) Under the temperature condition of 800°C, the tail gas of cyanuric chloride and methane are passed into the tail gas combustion furnace according to the gas flow ratio of 1:0.5, and the tail gas of cyanuric chloride and methane come into contact with combustion reaction, and the combustion generates carbon dioxide , nitrogen oxide, water and hydrogen chloride mixed gas, stay in the tail gas combustion furnace for 2 minutes, and enter the next process;
[0036] (2) in Al 2 o 3 loaded TiO 2 -V 2 o 5 -WO 2 Under the action of a catalyst, under the temperature condition of 700°C, the mixed gas obtained in step (1) is passed into the ammonia catalytic furnace, and ammonia gas is passed into the ammonia catalytic reaction at the same time, and the mixed gas and ammonia gas in step (1) are controlled. The flow ratio is 1:0.5; under the action of activated carbon catalyst, the mixed gas reacts with ammonia for 8 minutes, the nitrogen oxide in the mixed gas is converted...
