Until the floral disc for not crossing fixed filter core, while in filter bottom leading leaching connection low-pressure steam pipeline (Steam pressure control exists
Between 0.4-0.8MPa), low-pressure steam is passed through into filter, until desalination boiling water in filter, and continue 24 hours, so
After will remove steam, solution in filter is released and collects fixed placement.
Step 3：The NaOH weak solutions about 4m of 5%-10% is configured in water tank3(configuring solution using desalted water), then
NaOH weak solutions are transported in exhaust gas filter using centrifugal pump, until the floral disc of the excessively unfixed filter core of solution,
Filter bottom leads leaching connection low-pressure steam pipeline (Steam pressure control is between 0.4-0.8MPa), is passed through into filter low
Steam is pressed, until desalination boiling water in filter, and continue 24 hours, steam then will be removed, solution in filter will be released
And it collects fixed point and places.
Step 4：The alkali cleaning operation being repeated two more times in step 3.
Step 5：Desalted water is added again into filter and does not have filtration core, and (Steam pressure control exists using low-pressure steam
Between 0.4-0.8MPa) it boils 24 hours, liquid is released.
Step 6：Top blow valve 5 is dismantled into connection instrument supply gas, while leaching 4 is led into bottom and is dismantled, is passed through into filter
Instrument air takes the moisture content of internal residual out of.
Step 7：Blow valve and bottom showering guilding valve are closed, exhaust gas filter reaches stand-by state.
Preferably, the filter top is provided with offgas outlet, and side is provided with inlet exhaust gas.
Preferably, the filter interior is provided with filter core and fixes floral disc and filter core.
Preferably, the fixed floral disc is located at the top of filter core.
Preferably, the blow valve of the filter is also connected with instrument air feed system.During specifically used, it can lead to
Cross triple valve realization.
The beneficial effects of the utility model
(1) cleaning way of filter element is transformed in the utility model, and personnel is avoided to enter filter interior
It is again introduced into the operation sequence that filter is installed after carrying out dismounting filter core, washes clean, operating risk is not only reduced, reduces and make
Industry personnel labor intensity.
