The working principle and the working process are as follows:

when in operation, the automatic unloading machine 31 and the control valve 71 are closed, then the driving motor 40 and a sewage pump or an induced draft fan arranged outside the machine are started to carry out rough treatment on the original sewage or dust to be treated by a preposed rough filtration or cyclone dust remover, then the original sewage or dust to be treated enters the hollow shaft 3 from the water inlet pipe 41 through the water inlet hole I42 and the water inlet hole II 6 to be conveyed downwards, then the original sewage or dust is input into a space between the bottom circular plate 61 and the diversion circular plate 53 in the bottom-stage rotating drum 59 from the water inlet hole III 58 to flow to the slag blocking pipe 55 from the lower end, then the sewage or dust flows into the inner cavity of the whole bottom-stage rotating drum 59 through the water inlet hole I54 of the diversion circular plate 53, the water inlet hole II 20 of the middle circular plate 49 and the water inlet hole III 18 of the upper circular plate 47, then the sewage or dust in the rotating drum is subjected to solid-liquid or gas-dust centrifugal separation by various circular, the inflow is automatically stopped after the inner cavity of the sedimentation cylinder 25 is filled, because the pressure of the sewage or the dust flowing out of the slag hole 22 at the edge of the rotary drum is higher than the pressure of the sewage or the dust existing in the rotary drum under the action of the centrifugal force generated by the high-speed rotation of the rotary drum, and because the inner cavity of the sedimentation cylinder 25 is closed, after the inner cavity of the sedimentation cylinder 25 is filled with the sewage or the dust, the pressure of the sewage or the dust in the inner cavity is equal to the pressure of the sewage or the dust flowing out of each slag hole 22, when the rotary drum normally operates, the sewage or the dust in the rotary drum cannot flow into the inner cavity of the sedimentation cylinder 25 again after the inner cavity of the sedimentation cylinder 25 is filled with the sewage or the dust, but when the control valve 71 is opened to discharge the purified water or the purified gas which is secondarily separated, the pressure of the inner cavity of the sedimentation cylinder 25 is immediately reduced to be lower than the pressure of the slag hole 22, and then the sediment in the, when the sewage or dust in the inner cavity of the settling cylinder 25 is filled in the whole machine and normally operates, the sewage or dust water entering the inner cavity of the bottom-stage rotating drum 59 flows upwards into the middle-stage rotating drum 19 from the space between the diversion circular plate 53 and the middle circular plate 49, the space between the middle circular plate 49 and the upper circular plate 47 and the space between the upper circular plate 47 and the lower circular plate 57 in the upper-stage rotating drum to the water outlet two 50, the water outlet three 48 and the water outlet one 56 respectively at the upper end under the centrifugal separation action of centrifugal force, and then, further performing centrifugal separation in the original mode, enabling the separated purified water or purified gas to flow upwards into the top-stage rotary drum 17 from respective water outlets again for final centrifugal separation, enabling the separated purified water or purified gas to flow into the inner cavity of the upper bearing seat 5 from a top-layer water outlet 45 of the top-stage rotary drum 17 through the flow guide pipe 16, and then discharging the purified water or purified gas out of the machine through the upper water outlet pipe 8 from the water outlet hole I9.

When the sewage or dust in the inner cavity of the settling cylinder 25 is filled with the sewage or dust in the inner cavity of the settling cylinder 25 and the whole machine normally runs, the rotary drum assembly 24 driven by the hollow shaft 3 to rotate at a high speed simultaneously drives the sewage or dust in the settling cylinder 25 to rotate at a high speed for solid-liquid or gas-dust separation, after the control valve 71 is properly opened, the separated purified water or purified gas flows into the hollow shaft 3 from the water outlet hole two 62 and flows downwards into the inner cavity of the lower bearing seat 34, and then flows into the lower water outlet pipe 72 to be discharged out of the machine from the water outlet hole three 35, if the quality of the secondary separation water does not reach the standard, the separated purified water or purified gas can be sent into a sewage pump or an induced draft fan for secondary treatment, when the purified water or purified gas is discharged out of the machine after the control valve 71 is opened, the pressure in the settling cylinder 25 is correspondingly reduced, then the sediment in each sediment tank 52 in the rotary drum can be discharged into the inner cavity of the settling cylinder 25 from each sediment hole 22 for, therefore, after the multistage disc type sedimentation separator of the invention normally operates, the centrifugal separation effect of sewage or dust can meet the design requirements of continuous slag discharge of the slag basin 52 and continuous water discharge or air discharge of the lower water outlet pipe 72 as long as the flow of water discharge or air discharge of the control valve 71 is well controlled, and after the sediment in the sedimentation cylinder 25 is deposited to the set height, the automatic discharger 31 is opened at regular time to discharge the sediment out of the machine from the sediment discharge pipe 32. The electric appliances of each motor of the machine are controlled by an automatic control system which is additionally arranged.

On the basis of the above description, those skilled in the art can adopt the same structure and the same principle when facing the problem of dust treatment, and only need to adjust the parameters suitable for sewage treatment to the parameters suitable for gas dust treatment according to the conventional technology, and the description is omitted.
