| titleOfInvention | Nitro-chlorobenzene factory nitrification and acid fume absorb waste water extraction processing system |
| abstract | A kind of nitro-chlorobenzene factory nitrification and acid fume absorb waste water extraction processing system, including nitric acid storage tank, nitration mixture storage tank, concentrated sulfuric acid storage tank, sulfuric acid storage tank, tail gas storage tank is concentrated, tail gas absorption water tank, first alkali cleaning water storage tank, second alkali cleaning water storage tank, first jet pump, knockout drum, second jet pump, Benzene Chloride storage tank, knockout tower, third jet pump, in tail gas absorption tank top, four absorption plants are set, with by nitric acid storage tank, nitration mixture storage tank, concentrated sulfuric acid storage tank, sulfuric acid storage tank, concentration tail gas storage tank is connect with tail gas absorption water tank respectively, second jet pump, which mixes the waste water in the second alkali cleaning water pot with Benzene Chloride, to be sent into knockout drum, carry out first separation, knockout tower carries out secondary separation, the principle that the utility model utilizes acid-base neutralization to absorb, acid gas extra in storage tank is handled by soda-wash water absorption, it also proposed and utilize chlorine The scheme for changing the nitro compounds in benzene extraction soda-wash water, not only extracts nitro compounds, but also saved a large amount of steam. |
