초록 ▼

An impingement distributor for a shell and tube heat exchanger and a method of recovering waste heat from a hot gas which minimizes adverse heat flux at the outermost banks of tubes for enhanced operational reliability. The impingement distributor has a cylindrical distribution plate having evenly arranged rows of longitudinal perforations and a plurality of impact bars longitudinally aligned with the perforations. The hot fluid impinges on the impact bars, and direct impingement on the tubes is avoided.

A shell and tube heat exchanger, comprising: a tube bundle generally longitudinally disposed in the shell for passing a tube-side fluid through the exchanger; a shell-side inlet in fluid communication with an annular distribution channel defined by a cylindrical distributor plate disposed around the tube bundle and spaced from an inside surface of the shell; a plurality of perforations formed in the distributor plate to distribute fluid from the annular channel to flow through the tube bundle across outer surfaces of the tubes to a shell-side fluid outlet; a plurality of impact bars disposed between a bank of outer tubes of the bundle and an inner surface of the distributor plate wherein the bars oppose each of the perforations for fluid passing through the perforations to impinge on the bars and avoid direct impingement of the hot gas on the tubes. A method for recovering waste heat from a hot gas in a shell and tube heat exchanger having a tube bundle generally longitudinally disposed in the shell for passing a tube-side fluid through the exchanger, comprising the steps of: (a) directing the hot gas to an annular distribution channel of the shell and tube heat exchanger, the annular distribution channel in fluid communication with a shell-side inlet and defined by a cylindrical distributor plate disposed around the tube bundle and spaced from an inside surface of the shell; (b) distributing the hot gas from the annular channel to flow through a plurality of perforations formed in the distributor plate, through the tube bundle across outer surfaces of the tubes, and to a shell-side gas outlet; (c) impinging the fluid passing through the perforations against a plurality of impact bars disposed between a bank of outer tubes of the bundle and an inner surface of the distributor plate wherein the bars face the perforations; (d) transferring heat from the gas distributed by the distributor plate to the fluid flowing through the tube bundle; (e) withdrawing a cooled gas from the shell-side outlet and a heated fluid from a tube-side outlet.
