<p><P>PROBLEM TO BE SOLVED: To provide a gas purification apparatus which effectively removes harmful substances represented by volatile organic compounds (VOC) contained in a treated gas by being absorbed by a liquid solvent. <P>SOLUTION: The gas purification apparatus is for removing harmful substances represented by VOC from the treated gas 2 containing the substances. The apparatus is equipped with: a plurality of absorption tanks 101-105 serially arranged in the first to the final steps, and stored with absorption liquid 141-145 such as surfactants respectively absorbing the harmful substances; an introduction pipe 111 for introducing the treated gas 2 inside the absorption liquid 141 of the absorption tank 101 in the first step; communication pipes 112-115 for communicating with the outside the absorption liquid of the absorption tank in the pre-step and the inside the absorption liquid of the absorption tank in the following step; a discharge pipe 116 for discharging the treated gas 2 from the outside the absorption liquid 145 of the absorption tank 105 in the final step; a bubbling nozzle provided at the tips of the introduction pipe 111 and the communication pipes 112-115, and for making the treated gas 2 bubbles to discharge it inside the absorption liquid; and a jet water flow type blower 20 for sending the treated gas 2 from the introduction pipe 111 to the discharge pipe 116. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
