Movable demister system

Claim 1

A movable demisting system, including cleaning means for the continuous removal of any deposition of solid materials on the individual demisting members following their movement across the gas stream outlet portion of a gas contacting chamber, said system comprising in combination, a. a movable carrier means, a multiplicity of spaced apart and elongated demisting members of chevron type comprising parallely positioned, spaced apart zig-zag-form plate-like members to provide impingement surfaces and tortuous paths for the gas stream passing through said chamber, said demisting members being connected to said movable carrier means to thereby form a movable arrangement of gas contacting demisting members, b. said carrier means being positioned within and across a demisting portion of said chamber in a manner to carry said demisting members transversely across said chamber and across the path of the gas flow therethrough, c. drive means connective to said carrier means, whereby the latter and said connecting demisting members can be caused to be moved across said chamber, and d. a demisting member cleaning section connected to said chamber and pressurized liquid spray means therein positioned to encompass the full lengths of a portion of the demisting members connecting witH said carrier means, said cleaning section including a plurality of nozzle means as said liquid spray means to direct spray streams positioned both above and below said demisting members as said demisting members pass around sprocket wheel means of the drive means effecting a change in direction for said demisting members, said nozzle means being positioned to impinge upon the demister member surfaces as they effect a change in direction to again traverse the gas flow path through said chamber, whereby a cleaning liquid will spray over the surfaces of each member after it has moved across the gas stream flow path in said chamber so as to preclude a solids buildup on said members.
