Mist eliminator module and a method for self-cleaning of the same

A mist eliminator module for removing the liquid components of a gas stream, comprising:

• a plurality of smooth mist eliminator blades formed from a polymeric material, each blade having a captive edge portion and a free edge portion, and each blade being in substantial alignment with adjacent blades;
• support means for holding said captive edge portions, said support means having a plurality of resilient spacers separating said blades and being secured thereto;
• and
• detachable spacer means for holding said free edge portions in spaced alignment in slots formed in said spacer means for receiving said free edge portions;
• whereby each blade may be readily separated from adjacent blades after detaching said spacer means.

A mist eliminator module for removing liquid components of a gas stream, comprising:

• a plurality of parallel mist eliminator blades formed from a fiber reinforced polyester material, each blade having in one edge thereof at least one aperture aligned with apertures in adjacent blades;
• at least one support rod extending through said aligned apertures, said at least one rod having a plurality of resilient tubular spacers fitted onto said rod between said blades;
• and
• at least one spacer bar having a plurality of slots in one face thereof into which are inserted the edges of said blades opposite the said edges having apertures therein.

A self-cleaning mist eliminator assembly, comprising:

• a plurality of smooth mist eliminator blades formed from a polymeric material, each blade having a captive edge portion and a free edge portion, and having in said captive edge portion a plurality of apertures aligned with apertures in adjacent blades;
• at least one support rod extending through said aligned apertures, each said rod having a plurality of elastomeric spacers fitted onto said rod between said blades;
• at least one rigid spacer bar, each said bar having a plurality of slots formed in one face into which are fitted said free edge portion of said blades, and each said spacer bar being secured to at least one said blade;
• and
• a spray nozzle and water supply providing a spray of water droplets having a diameter of 200 to 300 microns directed to form a water film on said blades.

A method of self-cleaning deposited solids from the blades of a mist eliminator module having a plurality of mist eliminator blades formed from a smooth material, said module having support means for resiliently holding captive edge portions of said blades in spaced alignment, and detachable spacer means for holding free edge portions of said blades in alignment, and a spray nozzle and water supply providing a spray of water, wherein said module and spray nozzle are mounted inside a mist eliminator chamber, comprising the steps of:

• removing said detachable support means from said module;
• directing a spray of water droplets having a diameter of 200 to 300 microns at a pressure of at least 40 psig on said blades;
• and
• flowing air at an effective volume and velocity through said mist eliminator chamber to induce flexing and vibration of said blades sufficient to dislodge said deposited solids.

A method of self-cleaning deposited solids from the blades of a mist eliminator module having a plurality of mist eliminator blades formed from a polymeric material, each blade having a plurality of aligned apertures in one captive edge portion thereof, and at least one support rod extending through said apertures, each said rod having a plurality of resilient tubular spacers fitted onto said rod between said blades, and said module having at least one rigid spacer bar having a plurality of slots in one face into which are fitted the free edge portions of said blades, and a spray nozzle and water supply providing a spray of water, wherein said module and spray nozzle are mounted inside a mist eliminator chamber, comprising the steps of:

• removing said rigid spacer bar from the said free end portions of said blades,
• directing a spray of water droplets having a diameter of 200 to 300 microns at a pressure of at least 40 psig on said blades;
• and
• flowing air at an effective volume and velocity through said mist eliminator chamber to induce flexing and vibration of said blades sufficient to dislodge said deposited solids.
