In order to make the gravity be convenient to use, the boundary layer baffle 61 is arranged on the lower shell wall 111 of the volute 10, and the wet air channel 60 is arranged up and down.
In order to realize automatic cleaning, a cleaning layer 102 is arranged on the inner side of a cylindrical surface of the volute 10 which is different from the boundary layer, a vibration cavity 103 is arranged between the cylindrical surface of the volute 10 and the cleaning layer 102, two elastic strips 101 are arranged in the vibration cavity 103, the two elastic strips 101 are distributed on the edge part of the cleaning layer 102, the volute 10 and the cleaning layer 102 are fixed together through the elastic strips 101, the outer wall of the cleaning layer 102 is fixedly connected with a vibration contact of a vibration motor 17, and the cleaning layer 102 can vibrate under the driving of the vibration motor 17. By the vibration, the floating ash on the inner side of the cleaning layer 102 can be vibrated down.
In order to cooperate with the cleaning layer, referring to fig. 5-6, the inner surface of the cleaning layer 102 is fixed with a plurality of rows of cleaning block arrays, each row of cleaning block arrays comprises a plurality of cleaning blocks 30 which are arranged at equal intervals, the arrangement direction of each row of cleaning block arrays is perpendicular to the axial direction of the cleaning layer 102, and the cleaning block arrays are staggered (the staggered arrangement means that the cleaning blocks 30 of one cleaning block array are aligned with the middle position of the cleaning block gap of the other cleaning block array in two adjacent cleaning block arrays).
Referring to fig. 7, the cleaning block 30 is overall high in the middle and low in the front and rear sides, wherein the rear side is a windward side 31, the rear side is a leeward side 32, the boundary line between the windward side 31 and the leeward side 32 is a curve 33, the middle part of the curve 33 is located at the rear, the left and right sides are located at the rear, and the height of the curve 33 (i.e., the projection distance of the curve 33 to the cleaning layer 102) is gradually reduced from the middle to the left and right sides;

Referring to fig. 6, after entering the cleaning block alignment area, the annular wind 71 is generally divided into three directions: two bypass the left and right sides of the block 30, see reference numeral 72, and one passes over the windward face 31 of the block 30.
When the annular wind 71 passes by the left and right sides of the cleaning blocks 30, the wind speed of the area (see the reference numeral 80) between the two cleaning blocks 30 is increased, and dust or mud drops in the area are easily brought out; when the annular wind 71 passes over the windward surface 31 of the cleaning block 30, the wind is in a climbing state, the wind direction of the annular wind 71 is obliquely crossed with the windward surface 31, the dust or mud drops in the area are also promoted to be taken away by the annular wind at a large probability, and the wind speed and the vibration of the cleaning layer 102 are influenced with each other by matching with the vibration motor 17, so that the peak value of the instantaneous wind speed is larger, and the dust or mud drops can be taken away at a large probability.
In particular, after the cleaning block 30 is added, the peak value of the instantaneous wind speed becomes large, and in the case that the cleaning can be completed, the annular wind 71 can be caused to take away more liquid droplets, providing the dehumidification efficiency. When the annular wind flows across the windward side of the cleaning block 30, a low-speed stable vortex is formed at the leeward side, the air velocity of the boundary layer is reduced, small droplets are gathered, and the dehumidification efficiency is improved. Meanwhile, the cleaning block 30 is a smooth plane, so that the attachment of pollutants is not facilitated, and conditions are created for self-cleaning.

b = (0.8 — 1.5) × H, that is, B equals 0.8 to 1.5 times H, the same applies below;
L0=（0.3--0.8）*H；
L=（0.9--1.7）*H。
tests show that a cleaning block 30 of this size has a good cleaning effect.
The working principle is as follows:
through the effect of centrifugal fan organism 20 and blade 21, can form annular wind in the spiral case 10, from the air intake 16 air inlet, from the air-out of air outlet 11, this is prior art, and no longer repeated.
After the annular wind moves, under the influence of centrifugal force, small droplets in the volute 10 gradually deviate towards one side of the friction wall and enter the boundary layer, and the wind speed of the boundary layer is lowest in all the annular wind in the volute 10, so that the boundary layer has several characteristics: s1, the number of small drops is increased due to the fact that more small drops enter the area, the probability that the small drops are gathered into large drops is increased, and the large drops are less affected by wind and can be captured by the cleaning layer 102 more easily; s2, the risk of large droplets escaping past the boundary layer baffle 61 or the deflector 62 due to their weight is reduced.
Thus, after the liquid drops on the outer surface and inside of the boundary layer move to the boundary layer baffle 61, the liquid drops are blocked and guided by the boundary layer baffle 61 and the guide plate 62 and are forced to enter the wet air channel 60, and the mixture of the liquid drops and the air in the wet air channel 60 comes to the outside to perform dehumidification.
Thus, for dehumidifying all the annular wind, although the total water content in the wet wind channel 60 is small, the total water content in the unit volume in the wet wind channel 60 is large, the water removal amount corresponding to unit energy consumption is high, the performance price is good, and the method is suitable for popularization.
This patent is clean has two kinds of modes:
s1, cleaning in a dry state
In this case, there is substantially no liquid drop in the annular wind, and after the centrifugal fan is driven, the dust adhered to the inner surface of the cleaning layer 102 is separated from the cleaning layer 102 in cooperation with the vibration of the vibration motor 17, and then the dust is sent into the wet wind channel 60 by the annular wind to be treated outside.
In this case, the dust is a floating ash (or dry ash) substantially free of moisture, which is used for machine maintenance.
S2, cleaning in dehumidification state
In this case, dehumidification and cleaning are performed simultaneously, and at the same time of dehumidification, the probability of combination of liquid drops and floating ash (or dry ash) particles is increased, so that the liquid drops and the floating ash can be mud drops (mixture of water and floating ash), and similar to the liquid drops, the mud drops can also be conveyed to the outside for treatment.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
