专利汇可以提供High energy gas filtration method专利检索，专利查询，专利分析的服务。并且A cleanable gas filtration system is described for removal of liquid and solid particulate matter from air or other gas streams. The system operates in the ''''high energy'''' region at gas velocities of 300 to 4,000 feet per minute and pressure drops across the filter medium of 7 to 60 inches of water. The system employs as its filter medium a reticulated elastomeric foam, such as a fully reticulated polyurethane foam, having a void fraction of at least 90%. Submicron and larger size particles can be filtered with high efficiency, and dry solid, liquid and mixed particulate matter can be readily handled.，下面是High energy gas filtration method专利的具体信息内容。
1. IN A PROCESS FOR FILTERING MICRON AND SUBMICRON SIZE LIQUID AND SOLID PARTICULATE MATTER FROM A GAS STREAM BY MEANS OF A FILTER MEDIUM; WHEREIN THE VELOCITY OF SAID GAS STREAM AT THE UPSTREAM FACE OF SAID FILTER MEDIUM IS IN THE RANGE OF FROM 300 TO 4,000 FEET PER MINUTE AND THE PRESSURE DROP ACROSS SAID FILTER MEDIUM IS IN THE RANGE OF FROM 7 TO 60 INCHES OF WATER; AND WHEREIN SAID FILTER MEDIUM IS IN THE FORM OF A MOVABLE, REPLACEABLE, POROUS, GAS-PERVIOUS MAT; A PORTION OF SAID MAT BEING MOVED INTO THE GAS STREAM, LOADED WITH PARTICULATE MATTER,MOVED OUT OF THE GAS STREAM AND A FRESH PORTION OF SAID MAT BEING MOVED INTO SAID GAS STREAM TO REPLACE THE SPENT PORTION, ALL WITHOUT INTERRUPTING THE FILTERING PROCESS; THE IMPROVEMENT WHICH COMPRISES: A. UTILIZING AS SAID FILTER MEDIUM A MAT COMPRISING AT LEAST ONE LAYER OF A FLEXIBLE RETICULATED ELASTOMERIC FOAM HAVING A VOID FRACTION OF AT LEAST 90%; B.PASSING SPENT FILTER MEDIUM INTO CLEANING MEANS AND THEREIN REMOVING TRAPPED PARTICULATE MATTER FROM SAID FILTER MEDIUM;AND C. THEREAFTER RETURNING THE CLEANED FILTER MEDIUM TO A POSITION IN SAID GAS STREAM FOR REUSE THEREIN.
2. The improved process of claim 1 wherein said elastomeric foam is a polychloroprene foam.
3. The improved process of claim 1 wherein said elastomeric foam is a butadiene-acrylonitrile copolymer foam.

11. The improved process of claim 10 wherein said elastomeric foam has a void fraction in the range of 95% to 99%.
12. The improved process of claim 1 wherein said elastomeric foam is a polyurethane foam.
13. The improved process of claim 12 wherein said polyurethane foam has a pore density of 5 to 200 pores per inch.
14. The improved process of claim 13 wherein said polyurethane foam has a pore density of 20 to 125 pores per inch.
15. The improved process of claim 12 wherein said polyurethane foam is fully reticulated.
16. The improved process of claim 15 wherein said polyurethane foam has a void fraction in the range of 90% to 99%.
17. The improved process of claim 16 wherein said polyurethane foam has a void fraction in the range of 95% to 99%.
18. The improved process of claim 1 wherein said cleaning means comprises a chemical cleaning technique.
19. The improved process of claim 18 wherein said cleaning means comprises a solvent wash.
20. The improved process of claim 18 wherein said cleaning means comprises a water wash.
21. The improved process of claim 20 wherein said water wash also contains a soap or detergent.
22. The improved process of claim 1 wherein said cleaning means comprises a physical cleaning technique.
23. The improved process of claim 22 wherein said physical cleaning technique comprises ultrasonic cleaning.
24. The improved process of claim 23 wherein said ultrasonic cleaning means comprises an ultrasonic bath containing detergent.
