Airline vapor trap

An in-line trap for removing vapor from a compressed airline or the like comprising a manifold including spaced means defining an inlet and an outlet, and means between said spaced means for directing incoming air downwardly from said inlet and receiving air directed upwardly toward said outlet, enclosure means defining an enclosed volume suspended beneath and spaced from said manifold, first means mounted and extending between said inlet and said enclosure means for directing incoming air downwardly into said enclosed volume, said first means including means adapted to promote coalescence of vapor in air passing therethrough into droplets, second means mounted and extending between said enclosure means and said outlet for directing air from said enclosed volume to said outlet, means disposed within said enclosed volume to capture vapor droplets in air entering said enclosed volume, said capture means comprising means disposed in a lower portion of said enclosed volume to define a zone of substantially zero air movement, cross-sectional dimension to air flow in said enclosure means being substantially greater than within said first means, such that air velocity is reduced within said enclosure means and vapor droplets fall by gravity and centrifugal force toward said zone, and a plurality of vanes carried above said zone and angulated in a direction opposed to air flow within said enclosed volume.

An in-line trap for removing vapor from a compressed airline or the like comprising a manifold including spaced means defining an inlet and an outlet, and means between said spaced means for directing incoming air downwardly from said inlet and receiving air directed upwardly toward said outlet, enclosure means defining an enclosed volume suspended beneath and spaced from said manifold, a first cartridge having an outer wall and means disposed within said wall adapted to promote coalescence of vapor in air passing therethrough into droplets, means adapted removably to capture said first cartridge with said cartridge wall being mounted and extending between said manifold inlet and said enclosure means for directing incoming air downwardly into said enclosed volume, a second cartridge for removing vapor captured so as to be mounted and extend between said enclosure means and said manifold outlet for directing air from said enclosed volume to said outlet, and means disposed within said enclosed volume to capture vapor droplets in air entering said enclosed volume, said capture means comprising means disposed in a lower portion of said enclosed volume to define a zone of substantially zero air movement, cross-sectional dimension to air flow in said enclosure means being substantially greater than within said first means, such that air velocity is reduced within said enclosure means and vapor droplets fall by gravity and centrifugal force toward said zone.

A trap for removing oil and water vapor from a compressed airline or the like comprising

• a manifold including spaced inlet and outlet means adapted for coaxial in-line connection to a compressed airline and means adjacent said inlet means for directing incoming air downwardly,
• enclosure means having a bottom wall and a side wall suspended beneath said manifold and defining an enclosed volume,
• first means mounted and extending between said inlet means and said enclosure means for directing incoming air from said inlet means into said enclosed volume,
• said first means including means adapted to promote coalescence of vapors in air passing therethrough into droplets, droplets entrained in air entering said enclosed volume tending to fall by gravity toward a lower portion of said enclosed volume,
• an integral honeycomb structure disposed in said lower portion of said enclosed volume on said bottom wall and within said side wall, passages within said honeycomb structure extending downwardly toward said bottom wall and cooperating with each other and with said side wall to define a zone of substantially zero air movement for capturing falling droplets, and
• second means structurally separate from said first means mounted and extending between said enclosure means and said outlet means for directing air from within said enclosed volume to said outlet means, said second means including supplemental vapor absorption means comprising a mass of absorbent material and means for directing air through said absorbent material between said enclosed volume and said outlet.
