Abstract
A gas-to-liquid heat exchanger is presented, where a gas is introduced directly to liquid. The liquid is exposed to the gas as a liquid film upon a series of rotating heat exchange surfaces partially submerged in a liquid reservoir. The liquid vaporizes and then re-condenses on subsequent heat exchange surfaces, such that heat is exchanged between the gas and the liquid. Particulates within the gas coalesce into the vaporized liquid and collect into the liquid reservoir as the vapor re-condenses.
Claims24
A heat exchanger, comprising;
- a reservoir chamber configured to contain a liquid reservoir and a gas channel in contact with said liquid reservoir, said reservoir chamber further comprising a gas ingress end and a gas egress end, a liquid ingress port and a liquid egress port;
- and
- a rotating shaft comprising a first heat exchange surface in rigid rotational accompaniment with said rotating shaft, said rotating shaft disposed within said reservoir chamber such that said first heat exchange surface is configured to be partially submerged in said liquid reservoir and partially within said gas channel, said rotating shaft oriented to at least partially span said reservoir chamber gas channel.
A device, comprising;
- a housing;
- a reservoir chamber disposed within said housing configured to contain a liquid reservoir and a gas channel in contact with said liquid reservoir, said reservoir chamber further comprising a gas ingress end and a gas egress end;
- a rotating shaft comprising a heat exchange surface disposed to rotate around said rotating shaft in rigid accompaniment with said rotating shaft, said rotating shaft disposed within said reservoir chamber, said rotating shaft oriented to span at least a portion of said reservoir chamber gas channel;
- and
- a driver connected to said rotating shaft, said driver configured to rotate said rotating shaft.
A method for exchanging heat between a gas and a liquid, comprising the steps of:
- providing a reservoir chamber comprising a housing, a liquid reservoir and a gas channel in communication with said liquid reservoir and further in communication with said housing, said gas channel having a ingress end and an egress end;
- providing a rotating shaft at least partially spanning said reservoir chamber;
- providing a first heat exchange surface disposed upon said rotating shaft, said first heat exchange surface configured to rotate in rigid conformity with said rotating shaft;
- partially submerging said first heat exchange surface in said liquid reservoir;
- rotating said rotating shaft, thereby partially coating said first heat exchange surface with a liquid film;
- and
- introducing a gas through said gas channel ingress end to said first heat exchange surface;
- expelling said gas from said gas channel egress end.
A method for removing particulates from a gas, comprising the steps of:
- drawing a gas comprising particulates through a reservoir chamber partially filled with a liquid;
- within said reservoir chamber, rotating a first heat exchange surface partially submerged in said liquid;
- partially coating said first heat exchange surface in said liquid;
- introducing said gas to said first heat exchange surface in said reservoir chamber;
- and
- collecting particulates from said gas in said liquid.
