Problems solved by technology
[0004] During the recycling and granulation of waste plastics, when the temperature exceeds 200°C, the plasticizer and its internal low-boiling impurities will undergo oxidative decomposition, and the waste gas produced is mainly Including dust, aromatics, amines, hydrogen sulfide, phenols, aldehydes, acids, alkalis, unsaturated hydrocarbons and other odorous compounds, resulting in a foul smell in plastic waste gas, which seriously pollutes the local ecological environment , bringing hazards to surrounding residents and health and safety

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.
Description
technical field [0001] The invention belongs to the technical field of waste plastic utilization, and in particular relates to a waste gas treatment device for plastic granulation and plastic granulation. Background technique [0002] With the continuous increase in the demand for plastics, waste plastics are also gradually increasing, and the disposal of plastic waste is a major difficulty in the current environmental treatment. Recycling waste plastics is an environmentally friendly and economical approach. At this stage, my country's waste plastic recycling technology is still dominated by physical recycling. The recycling process mainly includes collection, classification and separation, cleaning, drying, crushing and granulation, and is modified and reprocessed to make products suitable for market demand or mixed with new materials. use. [0003] Recycling waste plastics is an environmentally friendly and economical approach, which includes physical and chemical method...
