| titleOfInvention | Gas-phase formaldehyde extraction system |
| abstract | The application discloses a gas-phase formaldehyde extraction system, which comprises a condensation system, a primary concentration system, a secondary concentration system, a pyrolysis separation system, a vacuum pumping system and a control system, wherein the condensation system is respectively connected with a first feeding pipeline for feeding formaldehyde aqueous solution and a second feeding pipeline for feeding alcohol; the first-stage concentration system is connected with the condensation system; the second-stage concentration system is connected with the first-stage concentration system; the pyrolysis separation system is connected with the secondary concentration system; the vacuumizing system is respectively connected with the primary concentration system and the secondary concentration system; the control system is respectively connected with the condensation system, the primary concentration system, the secondary concentration system, the pyrolysis separation system and the vacuum pumping system and is used for controlling the condensation system, the primary concentration system, the secondary concentration system, the pyrolysis separation system and the vacuum pumping system to operate. The system has the advantages of high purity of the gas-phase formaldehyde extracted by the system, stable operation of the system, high production efficiency and low production cost. |
