GN2 exhaust muffler

Abstract

A GN 2 exhaust muffler. The GN 2 exhaust muffler includes a first pipe and a second pipe. The first pipe has a first end and a second end. The first end of the first pipe is capped. The first pipe also includes a plurality of apertures that are positioned near the capped first end. The second end of the first pipe is adapted to receive a flow of GN 2 exhaust. The second pipe encases a portion of the first pipe such that the capped end and the plurality of apertures are housed in the second pipe. Moreover, the second pipe has an exhaust outlet adapted to output the GN 2 exhaust.

1 . A gas nitrogen (GN 2 ) exhaust muffler comprising: 
 a first pipe having a first end and a second end, the first end of the first pipe being capped, the first pipe also having a plurality of apertures near the capped first end, the second end of the first pipe adapted to receive a flow of GN 2  exhaust; and    a second pipe encasing a portion of the first pipe such that the capped first end and the plurality of apertures are housed in the second pipe, the second pipe having an exhaust outlet adapted to output the GN 2  exhaust flow.    
   
   
       2 . The GN 2  exhaust muffler of  claim 1 , further comprising: 
 the first pipe having a bend.    
   
   
       3 . The GN 2  exhaust muffler of  claim 1 , further comprising: 
 the exhaust output of the second pipe having a diameter that is smaller than the diameter of other portions of the second pipe.    
   
   
       4 . The GN 2  exhaust muffler of  claim 1 , the exhaust output of the second pipe further comprising: 
 a neck having a diameter that is less than the diameter of other portions of the second pipe.    
   
   
       5 . The GN 2  exhaust muffler of  claim 1  wherein the first pipe is made from one of a plastic and rubber.  
   
   
       6 . The GN 2  exhaust muffler of  claim 1 , wherein the second pipe is made from one of a plastic and rubber.  
   
   
       7 . The GN 2  exhaust muffler of  claim 1 , wherein the first and second pipe are made from a soft plastic.  
   
   
       8 . A method of manufacturing a gas nitrogen (GN2) exhaust muffler, the method comprising: 
 capping a first end of a first pipe that is adapted to receive a flow of GN2 exhaust in a second end;    forming a plurality of apertures in the first pipe near the first cap; and    encasing a portion of the first pipe with a second pipe such that the cap and the plurality of apertures are housed in the second pipe.    
   
   
       9 . The method of  claim 8 , further comprising: 
 forming a bend in the first pipe.    
   
   
       10 . The method of  claim 8 , further comprising: 
 forming a reduced diameter neck portion in the second pipe adapted to output the GN2 exhaust.    
   
   
       11 . The method of  claim 8 , wherein the first pipe and the second pipe is made from at least one of a plastic material and rubber material.  
   
   
       12 . A method of operating a gas nitrogen (GN 2 ) exhaust muffler, the method comprising: 
 receiving GN 2  exhaust flow in an inlet of a first pipe;    forcing the GN 2  exhaust flow out of a plurality of relatively small apertures in the first pipe; and    directing the flow of GN 2  exhaust out of an outlet of a second pipe, wherein the second pipe encases a portion of the first pipe having the relatively small apertures.    
   
   
       13 . The method of  claim 12  further comprising: 
 damping the noise created by the exhaust flow by using select materials in forming the first pipe and the second pipe.    
   
   
       14 . The method of  claim 12 , further comprising: 
 controlling condensation formed on the first and second pipe by using select materials in forming the first and second pipes.    
   
   
       15 . The method of  claim 12 , wherein the first and second pipes are made from at least one of a plastic and a rubber material.  
   
   
       16 . A method of processing a flow of gas nitrogen (GN 2 ) exhaust, the method comprising: 
 directing the flow of GN 2  exhaust through a muffler to reduce the noise produced by the flow of GN 2 .    
   
   
       17 . The method of  claim 16 , wherein the directing the flow of GN 2  exhaust through a muffler further comprises: 
 receiving GN 2  exhaust flow in an inlet of a first pipe;    forcing the GN 2  exhaust flow out of a plurality of relatively small apertures in the first pipe; and    directing the flow of GN 2  exhaust out of an outlet of a second pipe, wherein the second pipe encases a portion of the first pipe having the relatively small apertures.
