A kind of operation principle of deduster of the storage ash bucket in the application with fluidizer is described in detail below.
In intermetallic composite coating, as cut, in polishing and bruting process, will produce containing inflammable and explosive equal hazardous metals dust
Dusty gas；There may be the dusty gases containing oil smoke etc. with larger sticky dust in spray painting or other processing.It uses
When deduster provided by the present application purifies above-mentioned dust and gas, charging valve 6 is first turned on, by the way that charge door 5 is arranged on ash bucket 4, is pressed
Pre- coating and/or inerting agent 20 is added according to certain ratio, before dust-contained airflow is entered by dust and gas entrance 18 in dust and gas room 7,
Start the air-introduced machine 15 being arranged in air box 16, and opens the fluidizing gas control valve 23 being arranged on fluidizing chamber 102, warp
Fluidizing gas air inlet 22 is crossed, fluidizing gas is blasted into fluidizing chamber 102, fluidizing gas is by carrying mushy fluidized plate 2
Fluidization is generated to the pre- coating and/or inerting agent 20 that are placed on fluidized plate 2, and under the suction function of air-introduced machine 15,
Pre- coating and/or inerting agent are equably adsorbed on to the surface of sintered plate filter core 8, after reaching setting time, close fluidized gas
Body control valve 23 closes unloading valve 3, and opens dust and gas inlet valve 25 so that dust-contained airflow enters in dust and gas room 7, and straight
Connect and contacted with the pre- coating and/or inerting agent 20 for being adsorbed in 8 surface of sintered plate filter core, without with sintered plate filter core 8
Surface is in direct contact.After deduster runs a period of time, the control signal that can be sent out according to control cabinet 17 starts and is arranged net
Pulse-control system 10 in gas chamber 9, i.e. unbalanced pulse valve 12 one by one, pass through injection tube using the compressed air in gas bag 11 is divided
13 pairs of sintered plate filter cores 8 carry out blowbacks, can control the deashing of sintered plate filter core by differential pressure or timing mode, needed for pulse backblowing
Compressed air can be provided by external compressed air source by being filtered under diminished pressure valve 14.It is adsorbed in 8 surface of sintered plate filter core
Dust can again be fallen into storage ash bucket 1 through ash bucket 4 and unloading valve 3 by dust and gas room 7 under the active force of gravity and blowback air
Fluidized plate 2 on, unloading valve 3 can be closed according to actual needs, open the fluidizing gas control valve that is arranged on fluidizing chamber 102
23, by fluidizing gas air inlet 22, fluidizing gas is blasted into fluidizing chamber 102, Secondary Flow is carried out to the dust on fluidized plate 2
Change, repeat above procedure, until the pre- coating and/or the failure of inerting agent 20, clears up dust in the dust-collecting cavity 101, replace
Pre- coating and/or inerting agent 20, repeat the above process.
Using deduster provided by the present application in dust removal process, sticky dust is sufficiently mixed with pre- coating first, significantly
It reduces by the viscosity of dust in dust and gas, then is in direct contact with sintered plate filter core 8, so as to avoid the blocking of sintered plate filter core 8,
Or inflammable and explosive dust is sufficiently mixed with inerting agent first in dust and gas, the chemism of inflammable and explosive dust is passivated, significantly
