Abstract
In a thermal regeneration anti-pollution system in which there are a plurality of heat-exchange beds communicating with a high temperature incineration zone, excessive temperatures in the zone and danger to equipment in the installation are prevented by drawing off at least part of the hot gases therein. The gases are by-passed around the heat-exchange bed through which they would normally flow and then mixed in the exhaust with those incinerated gases which have been cooled through their normal passage through a heat-exchange bed.
Claims14
In a thermal regeneration system for processing an industrial exhaust gas flow or the like, the combination comprising:
- (a) a combustion chamber in which a high temperature range is maintained,
- (b) at least three separate stationary heat-exchange sections contiguous with and in communication with said chamber, each bed containing randomly disposed packing comprised of a plurality of solid heat exchange elements, said beds being bounded by vertical non-parallel walls,
- (c) a plurality of stationary inlet means, each being coupled to one of said beds, for conducting said gas flow to said bed for passage through it into said chamber,
- (d) a plurality of stationary outlet means, each coupled to one of said beds, for conducting said gas flow away from said bed after the gas flow has passed outwardly through said bed from said chamber,
- (e) fueled heating means within said chamber for continuously producing or maintaining said high temperature range, said temperature range being considerably higher than the temperature range of the gas flow as it first is applied to the apparatus and sufficiently high to cause continuous thermal oxidation of said gas flow,
- (f) means for sensing a predetermined temperature within said combustion chamber, and
- (g) means coupled to said chamber and to said sensing means for extracting a predetermined portion of the gases direct from said chamber when said sensing means detects said predetermined temperature, and
- (h) means coupled to said extracting means for mixing said extracted portion of gases with other gases from said exhaust which have been cooled by contact with at least one of said heat-exchange sections.
In thermal regeneration apparatus for processing an industrial exhaust gas flow or the like having three heat-exchange sections communicating with a high temperature combustion chamber and exhaust means, the heat controlling apparatus comprising:
- (a) a combustion chamber in which a high temperature range is maintained,
- (b) at least three separate stationary heat-exchange sections contiguous with and in communication with said chamber, each bed containing randomly disposed packing comprised of a plurality of solid heat exchange elements, said beds being bounded by vertical non-parallel walls,
- (c) a plurality of stationary inlet means, each being coupled to one of said beds, for conducting said gas flow to said bed for passage through it into said chamber,
- (d) a plurality of stationary outlet means, each coupled to one of said beds, for conducting said gas flow away from said bed after the gas flow has passed outwardly through said bed from said chamber,
- (e) fueled heating means within said chamber for continuously producing or maintaining said high temperature range, said temperature range being considerably higher than the temperature range of the gas flow as it first is applied to the apparatus and sufficiently high to cause continuous thermal oxidation of said gas flow,
- (f) an aperture formed in said combustion chamber,
- (g) conduit means coupled to said aperture for communicating with the interior of said chamber,
- (h) means for sensing a predetermined temperature within said chamber,
- (i) means coupled to said sensing means, to said conduit means and to said exhaust means for mixing a predetermined portion of said products of combustion drawn from said conduit with products of combustion appearing in said exhaust means, and
- (j) means for disposing of said mixed combustion products.
