Swirl flow type pre-mixed low-pollution combustion apparatus

Abstract

The disclosure relates to a waste gas purification apparatus, and more particularly, to a waste gas combustion apparatus to burn and process waste gases. The disclosure provides the waste gas combustion apparatus to process the waste gases generated in an industrial process, such as a chemical process, a semiconductor manufacturing process, or an LCD manufacturing process. The waste gas combustion apparatus includes a combustion gas supply unit provided with a first combustion region in which the waste gases are primarily burned by supply of fuel gases which are pre-mixed with diluted fuel gases, and a second combustion region which is supplied with support gases so as to completely burn fuel gases which are not reacted in the first combustion region.

What is claimed is: 
     
         1 . A swirl flow type pre-mixed low-pollution combustion apparatus to process waste gases generated in an industrial process, such as a chemical process, a semiconductor manufacturing process, or an LCD manufacturing process, the combustion apparatus comprising:
 a combustion gas supply unit provided with a first combustion region, the first combustion region being a space where a flame is formed by supply of pre-mixed fuel gases, which are pre-mixed with diluted fuel gases, and support gases; and   an ignition unit which includes an ignition device and is provided with a second combustion region, the second combustion region being a space where the flame formed in the first combustion region is diffused.   
     
     
         2 . The combustion apparatus according to  claim 1 , wherein the combustion gas supply unit is formed therein with the first combustion region, and further includes a gas nozzle member, which is provided with a pre-mixed fuel gas nozzle to inject the pre-mixed fuel gases and a support gas nozzle to inject the support gases. 
     
     
         3 . The combustion apparatus according to  claim 2 ,
 wherein the pre-mixed fuel gas nozzle is comprised of a plurality of pre-mixed fuel gas nozzles which are disposed to be inclined toward one side with respect to a radial direction so that the pre-mixed fuel gases are rotated in the first combustion region, and   wherein the support gas nozzle is comprised of a plurality of support gas nozzles which are disposed to be inclined toward one side with respect to a radial direction so that the support gases are rotated in the first combustion region.   
     
     
         4 . The combustion apparatus according to  claim 2 , further comprising:
 a waste gas supply unit provided with a guide pipe of which at least a portion is inserted into the first combustion region so as to supply the waste gases,   wherein the guide pipe is formed with a plurality of waste gas guide passages which are separated from one another.   
     
     
         5 . The combustion apparatus according to  claim 4 , further comprising a by-product processing unit to remove powders which are fixed on the waste gas guide passages. 
     
     
         6 . The combustion apparatus according to  claim 1 , further comprising:
 a third combustion region adjacent to the second combustion region,   wherein air is introduced into the third combustion region from the outside.
