Enter to a upper chamber, taper filter opening 1011 is conducive to being sufficiently mixed for industrial tail gas and absorbing liquid, to be conducive to organic matter
Removal;Open circulating pump 103, under the action of circulating pump 103, absorbing liquid by circulating line 104 reach washing tank 4 in by every
In multiple chambers that absciss layer is partitioned into, absorbing liquid carries out industrial tail gas to be sufficiently mixed absorption, while when industrial tail gas passes through
When taper filter opening 1011, cap-type filter plate 101 can be made to teetertotter, overhanging spring 102 can guarantee cap-type filter plate 101 in certain model
Interior shaking is enclosed, so that 101 transition of cap-type filter plate be avoided to shake the excessive bleed for causing absorbing liquid, the industry after absorbing liquid absorbs
Tail gas forms clean gas and is discharged from the gas vent 44 at 4 top of washing tank.
Clean gas passes through connecting tube 5 from gas outlet discharge, and 51 pairs of drying layer in connecting tube 5 absorb clean after washing
Residual liquid is absorbed in gas, and the clean gas after drying enters back into activated carbon adsorption case 6, activated carbon adsorption
Case 6 absorbs harmful organic substance remaining in clean gas, so by multistage exhaust treatment system, can achieve pair
The multistep treatment of VOCS tail gas guarantees the cleaning of the gas of discharge.
Industrial applicibility
According to the present invention, which can carry out multistep treatment to industrial tail gas, and then realizes the abundant of resource and follow
Ring utilizes, so that this processing system is useful in gas processing device field.
