Description
Technical field
The present invention relates to the workshop dust pelletizing system of cigarette manufacturing enterprise, particularly AF2/KDF2 filter stick formation unit dedusting structure.
Background technology
By diacetate fiber Shu Zucheng, and fibre bundle is by very long very thin can be separated from each other fibrous with filter tip for the cigarette that AF2/KDF2 filter stick formation unit is produced.Referring to Fig. 1, AF2 shredding gluing machine to the fibre bundle manufacturing procedure is: the curling waveform of tow 3 is from top to bottom transversely arranged along tow bag 1, and it is to utilize low-pressure air current (pressure 4 * 10 that tow 3 is introduced the first air-flow spreader 5, the first air-flow spreaders 5 through guide ring 4
550 cubes m/hs of flows), tow 1 is spread into needed width equably, apply constant tension force, before the second air-flow spreader 2 is installed in pre-withdrawing roll 6, after the first air-flow spreader 9 is installed in plucker roller group 9, the narrow slot length of " people " font of first, second and third grade spreader broadens step by step, the unpowered drivings of 6 pairs of pre-withdrawing rolls itself, clamp column is launched the tow of arc through first and second grade, enter plucker roller group 8 after making tow stable operation.
Plucker roller group 8 is comprised of preceding thread roller and rear thread roller, effect is that roller is to clamping the filament stretching and sending forward, adjacent monofilament is through plucker roller group 8 and pre-withdrawing roll 6, alternating tensile and loosen after, produce vertical misalignment and change curling position, then be sent to the 3rd air-flow spreader 9, to 10 tow inputted next procedure by outlet roller at last.Plucker roller group 8 and pre-6 pairs of tow alternating tensiles of withdrawing roll, roll the broken silk (being commonly called as " willow catkins flying in the air ") that prolongs generation, can collect by dust cover 7, the broken silk that moves in that is then blowed in the air by the 3rd air-flow spreader 9, causes air pollution.First, second and third air-flow spreader in the AF2/KDF2 filter stick formation unit is to pollute main emission source, and it pollutes the form that exists is stationary source, and the time of discharging is continuous source.
Broken silk belongs to the aerosol state pollutant, is suspended in the gas medium, and sedimentation can occur gravitate, but also can keep suspended state a certain period, enters airborne broken silk, as " willow catkins flying in the air ", can dilute diffusion.Wind is larger, and the dilution diffusion of pollutant is just faster; On the contrary, the dilution of pollutant diffusion is just slow, AF2/KDF2 filter stick formation unit, and the air pollution that it causes in process of production, alternately diffusion presents certain concentration and certain space.For above-mentioned situation, choose an AF2/KDF2 filter stick formation unit, the air quality situation of five points repeatedly adopts in the half meter scope of AF2/KDF2 filter stick formation unit of adjusting the distance, and the sampling number range of five points is added up: the particulate matter content of sampled point 1 is 45～51ug/m
3, the particulate matter content of sampled point 2 is 47～50ug/m
3, sampled point, 3 particulate matter content is 42～47ug/m
3, the particulate matter content of sampled point 4 is 51～55ug/m
3, the particulate matter content of sampled point 5 is 52～58ug/m
3, whole clean air particulate matter content is 10～20ug/m
3Hence one can see that, and sampled point 4,5 pollution condition are the most serious, and it is positive and parallel that these two points are positioned at AF2/KDF2 filter stick formation unit, and second and third air-flow spreader is the main emission source that pollutes.Next is sampled point 1,2, these two 2 are positioned at AF2/KDF2 filter stick formation unit behind, the dilution that is subject to pollutant extends influence, and sampled point 3 is positioned at silk bag the right, and broken silk pollutes when first, second air-flow spreader of its pollutant main source and tow fast lifting, teeter.
Cellulose acetate tow is as primary raw material, by artificial acetic acid synthesized cellulose, through curling the forming of weaving take natural fiber (wood-fibred or cotton fiber) and acetic anhydride, and meet the food hygiene requirement, but the air by broken silk pollutes can make the human body parts organ uncomfortable, such as eyes, nose and mouth.For causing respiratory disease, this pollutant of Long Term Contact can cause bronchitis, bronchial astehma, PUD D, comprises the impact on the human normal physiological function to the harm main manifestations of health.
