Abstract
The invention relates to an integrated treatment device for waste gas during plastic granulation. The integrated treatment device comprises an oxidation tower, an acid fog purification tower and an adsorption tower; a vertical device is formed by integrating the three towers sequentially from bottom to top, and horizontal devices are integrated sequentially from left to right. The waste gas enters the oxidation tower through a waste gas inlet and enters the acid fog purification tower through a central gas guide tube after being degraded through ozone and ultraviolet; afterwards, the waste gas passes through a gas distributor and a spray device, then enters the adsorption tower through the central gas guide tube, the acid fog purification tower and another gas distributor in sequence and is finally discharged from a purified gas outlet. The integrated treatment device is remarkable in treatment effect and has excellent oxygenolysis and absorption capacities on the waste gas during plastic granulation; besides, the occupied space is reduced, energy consumption and the cost are lowered, and therefore the integrated treatment device has a good application effect.
