Abstract

A gas cleaning and heat transfer apparatus has a plurality of gas cleaning units that concurrently operate to separate foreign matter from the gas and reduces the temperature of the gas. Each cleaning unit has a heat conducting wall surrounding a tubular passage for carrying gas and foreign matter. A plurality of helical elements located in the passage are positioned in angular relationship relative to each other so that the gas moving through the passage is divided into separate helical gas streams. Heat from the gas in the passage is transferred through the wall to the fluid. The jacket around the cylindrical wall has a generally spiral rib in one embodiment which directs the flow of liquid in the chamber in a spiral path. The heating liquid is pumped to a location where the heat in the liquid is utilized. In another embodiment a spiral fin surrounds the heat conducting wall and a relatively airtight jacket surrounds the fin. Air cools the heat conducting wall as it circulates in the jacket. The foreign matter is separated from the gas as it moves in the spiral path through the passage by the combined mechanisms of centrifugal force, adhesion, condensation, and impaction. The cool cylindrical wall causes condensation of vapors carried by the gas on the wall to facilitate the collection of foreign matter. The collected foreign matter flowing along the wall is carried by the moving gas to an annular collecting member.
