Embodiment 1
[0029] A treatment method for waste gas in the viscose fiber production process, comprising the following method steps:
[0030] A. Primary alkali spray pretreatment
[0031] Alkali spray towers are connected in series to form a first-stage alkali spray tower. Carbon disulfide and hydrogen sulfide waste gas pass through the first-stage alkali spray tower, and after alkali spray and filler interception, collision and absorption, hydrogen sulfide, a small amount of carbon disulfide and dissolved Volatile organic compounds;
[0032] B. Reaction decomposition
[0033] The exhaust gas pretreated by the first-level spray tower in step A is first dewatered through the buffer tank, and then transported to the low-temperature plasma device through the pipeline to decompose the pollutants in the exhaust gas into small molecular fragments;
[0034] C. Catalytic oxidation
[0035] Transport the waste gas from step B through the low-temperature plasma device to the catalytic oxidation t...
Embodiment 2
[0044] On the basis of embodiment 1:
[0045] Preferably, the wind volume of the exhaust gas is 50,000 m 3 / h, the first-stage alkali spray tower is two alkali spray towers connected in series, and the second-stage alkali spray tower is two alkali spray towers connected in series.
[0046] Preferably, the rated gas volume of the low temperature plasma device is 50,000 m 3 / h, maximum power 50Kw, input voltage 380v.
Embodiment 3
[0048] On the basis of embodiment 1:
[0049]Preferably, the wind volume of the exhaust gas is 100,000 m 3 / h, the first-stage alkali spray tower is 6 alkali spray towers connected in series, and the second-stage alkali spray tower is 6 alkali spray towers connected in series.
[0050] Preferably, the rated gas volume of the low temperature plasma device is 100,000 m 3 / h, maximum power 80Kw, input voltage 380v.
