Ash releasing tube 7 is discharged, and gas is entered in rotating-spray pipe 15 after buffering in buffer area 3 by gas port, and gas passes through rotation
Gas-guide tube on injection pipe 15 enters in separator tube 25, after the gas in separator tube 15 enters in curved pipe 26, due to
The internal diameter of curved pipe 26 be much smaller than separator tube 25 internal diameter, gas accelerates in curved pipe 26 ejection, due to curved pipe 26 by
The impact force of gas, rotating-spray pipe 15 are not stopped by the effect rotation of bearing 23 by gas injection to 14 surface of dust-catching board, dust suction
Since electrostatic adsorption is by the minute dusts absorption in gas, purified gas is discharged plate 14 by the exhaust pipe 6 at top,
When the dust of 14 adsorption of dust-catching board is more, shower water is added in water butt 19 by water inlet pipe 22, in water butt 19
Shower water is sprayed shower water from spray head 21 by rotary joint 20, the dust on 14 surface of dust-catching board is washed out, dust follows spray
Water drenching enters 1 bottom of device noumenon and is discharged by ash releasing tube 7, and variable-frequency motor 17 rotates, and water butt 19 is due to fixed block internal screw thread
It is used cooperatively with the external screw thread in rotary shaft 18 and horizontally slips in fixed link 16, it can be by all dust suctions in device noumenon 1
The dust on 14 surface of plate is rinsed well, so that dust-catching board 14 keeps efficient dust collection efficiency for a long time.
