| titleOfInvention | Sulfuric acid mist tail gas treatment device in anthraquinone production process |
| abstract | The utility model discloses a sulfuric acid mist tail gas treatment device in the anthraquinone production process, which comprises a first absorption tower; the second absorption tower and the third absorption tower are sequentially communicated with the first absorption tower; a spiral baffle is arranged in the first absorption tower; a packing cylinder is arranged in the second absorption tower, and graphite packing is filled in the packing cylinder; a plurality of downward-inclined baffles are arranged on the inner wall of the third absorption tower; the top ends of the second absorption tower and the third absorption tower are respectively provided with a first spraying device and a second spraying device; the first spraying device is communicated with a spraying liquid outlet arranged at the lower part of the second absorption tower; and the second spraying device is communicated with an alkali liquor outlet arranged at the lower part of the third absorption tower. The device can effectively improve the contact time of waste gas and spray liquid, thereby improving the treatment effect of the waste gas. |
