12, filtration system and electric-control system, the filtration system include cloth bag 9 and the bullet with spring cage that is arranged in inside cloth bag
Spring 13；The cloth bag 9 is unevenly spaced；Micro- vibration that the spring 13 is generated in ultrasonic wave air flow blowing is conducive to improve deashing
Efficiency.
The dust collection bucket 10 uses flat-bottom structure, is not easy buildup, efficiently solves dust in bag filter and exist
Immobilising problem is accumulated on the long taper ash bucket conical surface, also reduces device height.
The ultrasound generation device 12 includes supersonic generator and ultrasonic transducer.
It is divided into two-way after the alternating current input of 220 V50Hz, is used to generate high-power ultrasonics all the way, another way is used to examine
It surveys, the power supply function of control and display, specifically as shown in Figure 3.Wherein, inverter module is semi-bridge inversion, DC voltage inversion
For high-frequency ac voltage, then matching is boosted with the transformer of impedance matching module after tuning and inductance matches, can with high efficiency,
