Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 is dusty gas pipeline, 2 is the bag house of deashing state, and 3 is filter bag, 4 is back-blowing suction inlet, and 5 is back-blowing pipeline, and 6 is air bleeding valve, 7 is exhaust main, and 8 is blowback control valve, and 9 is the bag house of filtration condition, 10 is air-introduced machine, 11 is ash bucket, and 12 is supersonic generator, and 13 is ultrasonic oscillator, 14 is homogenizing plate, and 15 is ash discarding control valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1, ultrasonic coagulation negative pressure back-blowing bag-type dust collector described in the utility model comprises dusty gas pipeline 1, back-blowing pipeline 5, exhaust main 7, air-introduced machine 10 and two identical dust removing units, described dust removing units comprises bag house, filter bag 3 and ash bucket 11, the lower end of ash bucket 11 arranges ash discarding control valve 15, the upper end of ash bucket 11 is connected with dusty gas pipeline 1, installs homogenizing plate 14 in dust-contained airflow entrance top (ash bucket upper end).Space between homogenizing plate 14 and bag house lower end, surrounded by described deduster outer wall, as the chamber of ultrasonic wave process, supersonic generator 12 is fixed on described deduster outer wall, ultrasonic oscillator 13 probes into chamber interior by opening, supersonic generator 12 launches ultrasonic wave by ultrasonic oscillator 13 to chamber, filter bag 3 (being assembled by several small-sized filter bag unit) is inner at bag house by support installing, chamber is connected with filter bag 3, the upper end of bag house passes through air bleeding valve 6 and blowback control valve 8 is corresponding with exhaust main 7 and back-blowing pipeline 5 connected respectively, air-introduced machine 10 is arranged on exhaust main 7.
It is inner that the dust-contained airflow that dusty gas pipeline 1 will carry out filtering introduces deduster, homogenizing plate 14 enters chamber after making the dust-contained airflow entering deduster from dusty gas pipeline be assigned as uniform and stable air-flow, ensure that the ultrasonic wave that sends of ultrasonic oscillator 13 can abundant exposure cavity indoor air flow, extraneous air is introduced bag house by back-blowing pipeline 5 by back-blowing suction inlet 4, blowback control valve 8 is opened when air bleeding valve 6 is closed, enter deashing operation, air-introduced machine 10 is arranged on exhaust main 7, and air-flow filtration treatment crossed is discharged.Ash bucket 11 is arranged on bottom deduster, collects the dust filtered down, and after deashing terminates 2 minutes, open ash discarding control valve 15, the leaching in ash bucket 11 is poured out.
In Fig. 1, left side bag house is in filtration condition, and when dust-contained airflow is entered after in chamber by homogenizing plate 14, ul-trasonic irradiation is in dust-contained airflow, suspended particulate in air-flow starts to vibrate together with gas medium, have different Relative Vibration speed because suspended particulate varies in size, particle will collide bonding mutually, then can not follow ultrasonic vibration campaign greatly because particle becomes, but random Brownian movement, continue collision, bonding becomes large, reaches the effect of cohesion.Fine particle is after cohesion, and particle diameter obviously increases, and then enters bag house with air-flow, and due to the increase of particle diameter, it is increased greatly by the probability that filter bag 3 traps.In Fig. 1, right side bag house is in deashing state, when dust stratification on filter bag 3 to a certain extent after, open blowback control valve 8, wind outside enters in the bag house bag house 2 of deashing state (in the Fig. 1) by back-blowing pipeline 5, make to be in negative pressure state relative to outside in filter bag 3, there is deformation in filter bag 3, thus makes the dust stratification on filter bag 3 surface fall into ash bucket 11.Ash discarding control valve 15 is set bottom ash bucket 11, after deashing has operated 2 minutes, opens ash discarding control valve 15, the leaching in ash bucket 11 is poured out.Deduster in the course of the work, by the switch of by-pass valve control, can make filter bag in the bag house of both sides carry out deashing operation in turn, not affect the normal use of deduster.
Experimental example
Adopt containing dust air as trier, filter is same sack cleaner, and metrical instrument is dust particle measuring instrument, and humidity is not measured.Metrical instrument, in sack cleaner rear end, is collected filtered air sampled data, is compared with non-sampling by filtration data.Supersonic generator power output is 45W/cm
3, frequency is 24.1KHz.The time of staying of air-flow in chamber is at least 1 second, and (time of staying refers to that pending gas is from entering chamber to the time of flowing out chamber, namely pending gas accepts the time of ultrasonic wave process in chamber, hyperacoustic direction is vertical with pending gas flow, and homogenizing plate can be used as one of means controlling the time of staying).
Result shows, and ultrasonic wave process approximately reduces 20 ~ 30% than not applying the number of particles of ultrasonic wave process by sack cleaner.
Experiment proves, sack cleaner filter effect described in the utility model is more remarkable, is more than 1 μm particle, makes the removal ability of the utility model to microparticle stronger by ultrasonic coagulation by 0.3 μm of-1 μm of particle aggregation.
