Abstract

The invention discloses a waste-gas treating device of a waste-plastic recycling system. The waste-gas treating device comprises a gas collecting hood, a purifying box and a treating box, wherein thegas collecting hood is communicated with the bottom side of the purifying box by a gas delivery pipe; the inner wall of the purifying box, corresponding to a part above the gas delivery pipe, is provided with a blocking ring; a flow-limiting pipe is arranged on the upper surface of the blocking ring; through holes are uniformly formed in the surface of the flow-limiting pipe; a baffle plate is arranged at the top part of the flow-limiting pipe in a covering manner, and the flow-limiting pipe is arranged at the inner side of the edge of the baffle plate; a circulating water pump is arranged atthe outer side of the bottom part of the purifying box; one end of the circulating water pump is communicated with the bottom part in the purifying box by a pipeline. The waste-gas treating device disclosed by the invention has the beneficial effects that by arrangement of the baffle plate and a flow-limiting plate, waste gas passes through a flow-limiting drum to reach the bottom part of the baffle plate; convex blocks at the bottom part of the baffle plate can adsorb particles in the waste gas.

Description

Technical field: [0001] The invention relates to a waste gas treatment device, in particular to an environmental protection purification device for waste plastic regenerated waste gas. Background technique: [0002] With the improvement of people's living standards, a large amount of plastic waste is produced every day, and these wastes have high recycling value. 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] During the recycling and granulation of waste plastics, when the temperature exceeds 200°C, the plasticizer and its internal low-boiling impurities will be oxidized and decomposed, and the was...
