System includes blowback solenoid valve 15, gas bag 16 and blowback control cabinet 113, and blowback solenoid valve 15 and gas bag 16 are located at high efficiency filter section
Inside 1, and it is arranged in the side that card 14 is located at return fan section, since solenoid valve 15 and gas bag 16 are close to card setting, because
This does not need setting blowback injection tube, can be by the spray for the blowback solenoid valve 15 being arranged in a one-to-one correspondence with the filter cylinder ventilation hole on card
Filter cylinder ventilation hole on mouth alignment card, the import of blowback solenoid valve 15 are directly connected to gas bag 16
Entered inside whole dust removal unit containing fume gases by air returning valve 21, by filter cylinder group efficient in high efficiency filter section
Part purification, the filter cylinder surface of efficient cartridge assembly are covered with polytetrafluoroethylene film, can filter out 0.1 μm of partial size of flue dust, by filtering
Air a part afterwards, which is sent to after subsequent Air Treatment Technology section carries out heat exchange or dehumidification treatments, to be sent back in plant floor,
Another part is discharged into atmosphere by exhaust duct, meets atmosphere pollutants emission standards.
Soot dust granule is adsorbed on the surface of filter cylinder, and the pressure difference being externally provided with inside and outside pressure difference switch detection filter cylinder in filter cylinder works as filter
Cylinder surface by flue dust block to setting pressure difference when, by blowback solenoid valve 15 control abrupt release gas bag 16 in compressed air,
By blowout reversed on the inside of filter cylinder, the dust such as flue dust that filter cylinder surface is adhered to are blown off, are dropped into ash bucket 17.It is set on the outside of unit
Pulse control instrument is installed in the blowback control cabinet 113 set, controls the switch of blowback solenoid valve 15, is opened in blowback solenoid valve 15
When, the compressed air of the 0.4-0.6MPa stored in gas bag 16 blows to filter cylinder by blowback injection tube.When being filled with ash in ash bucket 17
After dirt, gate valve 19 is pulled open, dust can drop into ash bucket 111, then turn off gate valve 19, and lifting turntable 110 is downward
Ash bucket 111 can be hauled out and pour out dust, again put back to ash bucket 111 above lifting turntable 110 after cleaning out by rotation,
Rotation compresses ash bucket 111 and ash bucket 17 to control lifting turntable 110 upwards.
When the flue dust being blocked is when filter cylinder surface constantly deposits, 15 timing of blowback solenoid valve for controlling compressed air is beaten
(it, which is blown the time and is blown interval, is completed by the micro computer sequential control instrument in blowback control cabinet 113) is opened, at this point,
Oil-free anhydrous compressed air (installing oil water separator in the admission line position of blowback injection tube 114) is clear through pipeline inflow blowback
System is swept, filter cylinder inner surface is sprayed to by 114 moment of blowback injection tube of cleaning agency, the dust particles that will be deposited on filter cylinder
Vibration disengaging filter cylinder surface is generated with the effect of high pressure draught and falls into ash bucket 17, so that entire filter cylinder surface all recycles and obtains
It cleans (purging system can also be by manually controlling).
Deashing mode can choose there are two types of mode: pressure difference blowback mode and timing blowback mode.What is generally defaulted is fixed
When blowback mode.When being in pressure difference blowback mode, after whole dust removal unit operation a period of time, filter cylinder external surface area expires powder
Dirt, suction air volume will reduce, and filter core resistance increases.When filter cylinder inside and outside differential pressure reaches the setting value of pressure difference switch, pressure difference switch
An electric signal will be exported to the impulse generator in blowback control cabinet 113, after micro computer is handled, control blowback solenoid valve 15
Every 15 seconds (the deashing interval time between two filter cylinders, can reset according to the actual situation) each filter cylinder of cycle purge
(blowback solenoid valve 15 purge each filter cylinder time be 0.3 second), until dust on surface of filter cartridge purging is clean, filter cylinder inside and outside differential pressure is low
Stop purging in the setting value post-purge system of pressure difference switch.When being in timing blowback mode, blowback system recycles immediately to be blown
Sweep (its purge interval time be 15 seconds), dust stratification is how many around the control of this cycle purge and filter core and filter core inside and outside drag size without
It closes.
The control mode of blowback system can refer to existing deduster blowback control technology, and the present embodiment is not herein to blowback
The specific control program of control is repeated.
Blowback solenoid valve 15 and gas bag 16 in the blowback system of the present embodiment are set along in high efficiency filter section 1
Portion.
Embodiment two
Industrial premises entirety dust removal unit in the present embodiment is another preferred embodiment of the utility model, with embodiment
One the difference is that: the blowback system of high efficiency filter section 1 includes blowback solenoid valve 15, gas bag 16,113 and of blowback control cabinet
Blowback injection tube 114, blowback solenoid valve 15 and gas bag 16 are located at outside high efficiency filter section 1, and blowback injection tube 114 is arranged in card
14 are located at return fan section side, and are connected to gas bag 16, which is provided with the one-to-one nozzle of filter cylinder ventilation hole on card,
Blowback solenoid valve 15 is arranged between blowback injection tube 114 and gas bag 16.Blowback solenoid valve in the present embodiment in blowback system
15 and gas bag 16 be set along the outside top in high efficiency filter section 1, protruded by blowback injection tube 114 and be installed to high efficiency filter
Inside section 1, this avoid electric components such as solenoid valves because the attachment of soot dust granule causes blowback system to fail.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
