The problem of blocking except efficiency deficiency and filler or filter screen improves the removal effect of harmful exhaust in chemical industry to the utmost
Fruit, test prove that removal rate can achieve 99%.
Compared with prior art, the multistage aerosol wash mill of the application can be effectively removed is produced in the industrial production
Raw Tail Gas, and have that structurally reasonable, removal efficiency is high, filtration pressure is reduced, is not easy to plug and with long service life excellent
Point.
Fig. 2 is the flow chart of the multistage aerosol wash mill washing methods of one embodiment of the application.It is retouched below with reference to Fig. 2
State the process that exhaust gas in one embodiment is cleaned.
Firstly, in step s 11, exhaust gas is introduced in multistage aerosol wash mill by air inlet 1, carry out continuously
Filtration washing purification.
In step s 12, exhaust gas to be washed carries out just first for the first time by the spray system in aerosol washing unit
The filtration, purification of step, the spray system are for example made of two spraying mechanism A and a spraying mechanism B.Then in step S13
In, cleaned gas passes through aerosol processor for the first time and is further filtered.Here spray system and aerosol processor can
To be one or more, spray system includes the spraying mechanism A and spraying mechanism B of different number, and according to be washed
The type of exhaust gas can choose the structure and quantity of the filter screen in aerosol processor.Then, in step s 16, exhaust gas enters
It is settled to plenums, the impurity and particulate matter being further reduced in gas.In step S17, gas is left in clean air
Again by aerosol processor before mist wash mill, guarantee the removal effect for realizing high quality.Finally, in step S18, clearly
Multistage aerosol wash mill is discharged by gas outlet in clean gas.In addition, in preferred embodiments, between step S13 and S16
Inserting step S14, S15.In step S14, the gas for obtaining step S13 is again by spray system；In step S15,
The gas for obtaining step S14 is again by aerosol processor.
In another embodiment, it can be washed and fill directly off multistage aerosol after through plenums by clean air
It sets.
