2. A centrifugal smoke purifier according to claim 1, wherein: the lower part of the absorption barrel (1) is provided with a manhole (1.3) which is communicated with the lower absorption part and provided with a detachable cover body.
3. A centrifugal smoke purifier according to claim 1, wherein: the power source is a motor with a speed reducer, and the end part of the rotating shaft (3) is connected with the motor through the speed reducer.
4. A smoke cleaning method using the centrifugal smoke cleaner of claim 1, wherein:
step one: introducing smoke and smoke-cleaning liquid to be purified into a lower absorption part at the lower part of a bottom plate (6) through an inlet (1.1);
Step two: the first step is carried out, meanwhile, the rotating shaft is driven to rotate by an external power source, the rotating shaft drives the impeller to rotate, air and liquid in the upper absorption part and the lower absorption part are driven to do centrifugal motion by the rotation of the impeller, and smoke cleaning liquid and smoke to be cleaned in the lower absorption part do centrifugal motion in the process and gradually move upwards, so that the smoke cleaning liquid enters the upper absorption part through the bottom plate through hole (6.1);
When the smoke cleaning liquid and the smoke to be cleaned do centrifugal motion, the smoke cleaning liquid is uniformly stirred and mixed, and harmful substances in the smoke can be cleaned by the smoke cleaning liquid in the process, so that the cleaned smoke can be safely and reliably discharged;
step three: when the smoke-purifying liquid and smoke mixture enter the upper absorption part due to the action of centrifugal force, the liquid is thrown out from the water outlet (1.2) and enters the external water circulation equipment connected with the water outlet;
step four: when the second step and the third step are carried out, the purified smoke can rise upwards through the through holes (4.1) of the flange plate and is safely discharged through the smoke outlet;
In the second step, when the smoke cleaning liquid and the smoke are mixed for centrifugal movement, the mixture of the smoke cleaning liquid and the smoke cannot exceed the flange due to the effect of the flange, and the flange plays a role in blocking, so that the smoke cleaning liquid and the smoke are fully absorbed and purified; and the purified smoke can rise through the through holes in the rotating process of the impeller.
