Definitions

  • Another object of the present invention is to provide a wet gas scrubber in which the cross-sectional area of the gas passage can be varied in response to the changes of the gas flow rate and which has excellent characteristics as an actuating part for the controlling device.
  • An example of the rotor 3 to be used in this embodiment as shown in FIG. 2 is a rectangular column which has such a right cross-sectional area as the area enclosed by any closed curves and in which the ratio of the length to the width of the cross section is different. Therefore, by rotating a rotor axis 4 intersecting at right angles with the longitudinal axis of gas flow, the cross-sectional area of the throat pan can be made variable, the fluid resistance can be reduced and further the rela tion between the control variable and the gas flow rate can be made a linear function.
  • a solid having a closed and curved surface can also be used instead of the above mentioned rectangular column.
  • the relation between the control variable and the gas flow rate can be made to be a linear function.
  • the gas velocity gradually decreases and the dynamic pressure of the high velocity gas in the narrowest part is effectively recovered as a static pressure.
  • the clearances in the narrowest parts in the throat pans B and Q of the present gas scrubber are varied so that the gas passing cross-sectional area of the narrowest parts can correspond to the respective gas flow rates. Further, by making the gas velocity in the narrowest part constant, the pressure loss and dust collecting efficiency can be kept constant.
  • a gas scrubber as claimed in claim 1 in which said gas flow guides are wedge-shaped with the broad ends at said movable mechanism.
  • a gas scrubber as claimed in claim 1 in which said movable mechanism comprises a pair of spaced flexible and stretchable plate members extending along the inside portions of the throat parts, and plate moving means between said plate members and coupled to said plate members for bending the plate members outwardly into the throat parts.
