| titleOfInvention | A low-concentration formaldehyde waste gas recycling and disposal device |
| abstract | The utility model discloses a low-concentration formaldehyde waste gas recovery and disposal device, which comprises a concentration tower and a washing tower, the washing tower is connected behind the concentration tower, and the two towers are connected by an intermediate flue. After the high-temperature waste gas containing formaldehyde is dedusted, the formaldehyde aqueous solution produced by the absorption of formaldehyde is concentrated by the two-stage washing method. The concentration tower adopts the dynamic wave washing method to concentrate through appropriate liquid-gas ratio and liquid circulation to produce more than 30% formaldehyde aqueous solution; then The formaldehyde and residual impurities in the exhaust gas are further removed by the scrubber, and finally discharged to the atmosphere after efficient demisting. The equipment is simple, easy to operate, saves investment and land occupation, and can realize the recovery and resource utilization of formaldehyde under normal temperature and pressure conditions. The formaldehyde recovery rate can reach more than 90%, and the application prospect is wide. |
