Abstract
A mist elimination device in the form of a hood for the removal of moisture from a gas stream treated by a WESP includes a series of gutters on the outer surface of the hood to trap liquid droplets and direct the moisture to channels to drain to the lower region of a housing. Gutters are also provided on the interior surface of the hood to catch liquid droplets carried by the gas stream into the interior of the hood.
Claims5
A method for removal of moisture from a gas stream, which comprises:
- passing said gas stream to a mist eliminator device comprising:
- a chamber having an upper inlet for said gas stream, a lower outlet for collected liquid and a second outlet for product gas stream,
- a hood located generally axially in said chamber having walls sloping downwardly from an upper crown to a lower extremity defining an exterior and a space beneath the hood,
- at least one moisture collection channel provided on the exterior surface of said walls positioned to collect liquid on said walls and guide the collected liquid to at least one flow channel positioned to direct collected liquid to below the hood,
- at least one moisture collection channel provided on an interior surface of the walls positioned to collect liquid entrained in the gas stream and passing from the exterior of the hood into the space beneath the hood, and
- an outlet duct communicating with the space beneath the hood and joined to the second outlet for guiding gas entering the space beneath the hood to the second outlet,
- passing said gas stream downwardly from said inlet into engagement with the exterior surface of the walls,
- collecting moisture from the exterior surface of the walls in said at least one moisture collection channel provided on the exterior surface of the hood and guiding said collected liquid to said at least one flow channel and to below the hood,
- removing collected liquid guided to below the hood from said lower outlet,
- passing said gas stream into the space below the hood and collecting extrained moisture from said gas stream by said at least one moisture collection channel provided on the interior surface of the hood, and
- passing said gas stream to said second outlet through said outlet duct as said product gas stream.
