2These gases are spread in space harm workman and human beings'health.People often use the big sack cleaner dedusting of atmosphere blowback, and being in operation exists following subject matter: 1. the cloth bag ash-removal effect is bad, and filter bag appearance divinatory symbol dirt is too thick, and SR increases.Current domestic sack cleaner difficult point technically is exactly a filter-bag blowing deashing hard nut to crack, and the terminal deashing of most its cloth bags of filter bag of dust collector deashing is unclean, and resistance of the filter bag is increased, and impels full dust pelletizing system effect to reduce.2. the cloth bag resistance increases, and SR strengthens, and range hood mouth effect is bad.3. cover mouthful negative pressure is little, particularly oxygen blast, and a large amount of flue dust fills the air in the workshop contaminated environment during tapping, the harm workers ' health.4. SR increases the running current increase.5. can only improve the blowback air quantity because bag appearance divinatory symbol dirt is too thick, limited can't the reaching but equipment is exerted oneself makes the equipment operation abnormal.6. the device systems resistance increases has increased power consumption, has strengthened the part of appliance wearing and tearing, reduces the life-span, has increased dimension inspection expense.7. pick-up performance is bad, and useful Dust Capacity reclaims and reduces, and benefit reduces.8. the dust removal installation effect is bad, and dust flies upward infringement workman health sometimes, and the workman suffers from anthraco-silicosis, and the political fallout that causes and the social benefit of generation can't be calculated with money.
The utility model content:
The utility model purpose provides a kind of jetting deashing device of pulse bag type dust collector, improves efficiency of dust collection and ash-removal effect, increases the service life, and the protection environment solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the jetting deashing device of pulse bag type dust collector is formed and is comprised winding-up airduct, jet pipe, induces induction tunnel and filter bag, jet pipe is arranged on the winding-up airduct, be positioned at the top of filter bag, on jet pipe, arrange some induction tunnels of inducing.
Jet pipe and to induce the quantity of induction tunnel all be arbitrarily preferably is provided with two on jet pipe and induces induction tunnel.Jet pipe is arranged vertically on the winding-up airduct, induces that induction tunnel is oblique to be arranged on the jet pipe, induces the airflow direction of induction tunnel to point to filter bag.
Adopt the utility model, induce induction tunnel, improved efficiency of dust collection and ash-removal effect owing on jet pipe, set up, have the following advantages: 1. converter air-suction cover mouth negative pressure increases, dust arrestment rate reaches more than 90%, purifies surrounding environment, reduces the operator is endangered.2. the filter-bag blowing effect obviously improves, and filter bag does not have the too thick phenomenon of divinatory symbol ash, and SR is at 1000-1200Pa, stable operation under the nominal situation.3. the total system purification efficiency improves by original 89% and brings up to 96%.4. good seal performance reduces the loss of leaking out, and former leaking out at 10-18% now is controlled at below 10%.5. useful dust yield obviously increases, and per hour reclaims former every day about 4t, now per hour reclaims 5.5-7t, has increased recovery value.6. prevent that the operator from suffering from professional anthraco-silicosis, the benefit that environment purification brings can't accurately be calculated with amount of money.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram.
Among the figure: electromagnetic impulse valve 1, winding-up bellows chamber 2, winding-up airduct 3, jet pipe 4 is induced induction tunnel 5, filter bag 6.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the jetting deashing device of pulse bag type dust collector is formed and is comprised winding-up airduct 3, jet pipe 4, induces induction tunnel 5 and filter bag 6, jet pipe is arranged on the winding-up airduct, be positioned at the top of filter bag, on jet pipe, arrange some induction tunnels of inducing, be provided with two on the jet pipe and induce induction tunnel, jet pipe to be arranged vertically on the winding-up airduct, induce that induction tunnel is oblique to be arranged on the jet pipe, induce the injection direction of induction tunnel to point to the top of filter bag.Winding-up airduct 3 is connected with winding-up bellows chamber 2, on the winding-up bellows chamber electromagnetic impulse valve 1 is set and controls.The utility model embodiment is also supporting following improvement: 1. quote the advanced low voltage electromagnetic pulse valve of DSF-100 (G4 " 1); jetting pressure guarantees that under the operating mode of 0.3-0.5MPa filter bag ash removal is thorough; it is unclean to have removed the terminal winding-up of filter bag in the past, the defect that the grey thick resistance of divinatory symbol increases.2. the original filter bag diameter of the improvement of filter bag specification is that Φ 300 * 10000 is improved to diameter of phi 160 * 9600 specifically, and diameter reduces to improve the winding-up effect, and filter area is by original 22000m
