Description

Deep purification system for tobacco shred particle-containing waste gas of winding dust removal room Technical Field The utility model relates to an exhaust gas treatment system, in particular to a deep purification system for tobacco shred particle-containing exhaust gas of a winding dust removal room. Background In the wrapping procedure of cigarette production, the main function of the dust removal room is to collect and process dust and tobacco shred fragments generated in the production process, so that the waste gas of the wrapping dust removal room generally contains tobacco shred particles, dust and peculiar smell molecular substances, and the waste gas does not meet relevant regulations if directly discharged and can be discharged after being purified to a certain standard. In the prior art, as disclosed in Chinese patent No. 201310014071.2, the treatment method of the waste gas in tobacco production is characterized in that the waste gas generated in the process of wrapping dust removal production is collected into a waste gas collecting pipeline, so that the waste gas passes through a section of one-stage high-efficiency cross flow washing tank equipment, the effect of the washing tank is mainly to remove particles, dust and ammonia gas which is easy to dissolve in water, organic acids and peculiar smell molecular substances which are easy to dissolve in water in the waste gas, the peculiar smell molecular substances and the particles in the waste gas after the waste gas is treated by the section of one-stage high-efficiency cross flow washing tank are basically removed, in the concrete scheme, the washing tank comprises a cross flow waste gas treatment system, the cross flow waste gas treatment system consists of a polypropylene multi-face hollow ball filler filled in a purification cavity, a front spraying system and an upper spraying system, the front spraying system is arranged on the front side of the polypropylene multi-face hollow ball filler, the upper spraying system is arranged above the polypropylene multi-face hollow ball filler, a water tank is arranged below the front side of the polypropylene multi-face hollow ball filler, a gas-liquid separator is arranged on the rear side of the polypropylene multi-face hollow ball filler, the waste gas also needs to be treated by the gas separator, the air flow from the gas separator is inclined to form a plurality of flow channels which are inclined to form a liquid film along the air flow of the air flow, and the air flow is discharged along the inertia of the multi-face separator. In the above-mentioned publication, the waste gas of the dust-removing room is passed through a "one-stage high-efficiency cross-flow washing pool device", the spraying system directly acts on all the particulate matters, dust and peculiar smell molecular substances in the waste gas, the particulate matters and dust can be preferentially combined with the liquid medium for removing peculiar smell, especially the particulate matters and dust of large particles can seriously affect the combination of the liquid medium for removing peculiar smell to the peculiar smell molecular substances, only the liquid medium for removing peculiar smell can be excessively sprayed to achieve the peculiar smell removing effect, not only the waste of the medium is caused, but also the ideal peculiar smell removing effect is difficult to achieve, and on the other hand, the classified recovery of the separated substances (such as solid particle dust, waste residue and waste liquid) cannot be realized.
