Receiver-separator unit for liquid injected gas compressor

Claim 2

A RECEIVER-SEPARATOR TANK FOR A LIQUID INJECTED GAS COMPRESSOR SYSTEM COMPRISING: AN ELONGATED TANK PORTION FORMING A FIRST COMPARTMENT AND COMPRISING A LIQUID RESERVOIR, A CONDUIT EXTENDING INTO SAID PORTION FOR CONDUCTING A GASLIQUID MIXTURE INTO SAID FIRST COMPARTMENT, A SECTION OF SAID TANK FORMING A SECOND COMPARTMENT AND COMPRISING A VERTICALLY DISPOSED CYLINDRICAL SECTION FORMED INTEGRAL WITH SAID ELONGATED TANK PORTION AND INCLUDING A SIDE WALL PORTION EXTENDING INTO SAID ELONGATED TANK PORTION, A PORTION BETWEEN SAID FIRST AND SECOND COMPARTMENTS FORMED BY A TRANSVERSE PLATE DISPOSED ACROSS THE LOWER END OF SAID TOWER SECTION WHICH IS DISPOSED IN SAID ELONGATED TANK PORTION, AN OPENING IN SAID PLATE ADMITTING A GAS-LIQUID MIXTURE TO SAID SECOND COMPARTMENT, AN OUTLET CONDUIT DISPOSED ON THE SIDE WALL OF SAID TOWER SECTION ABOVE SAID ELONGATED TANK PORTION AND CONNECTED TO SAID SECOND COMPARTMENT, LIQUID SEPARATOR MEANS COMPRISING A HOLLOW CYLINDRICAL ELEMENT HAVING A POROUS WALL STRUCTURE AND DISPOSED IN SAID SECOND COMPARTMENT TO HAVE ONE END IN SEALING ENGAGEMENT WITH SAID PLATTE AND SURROUNDING SAID OPENING, MEANS FORMING A CLOSER FOR THE END OF SAID ELEMENT OPPOSITE SAID ONE END, SAID ELEMENT DEFINING AN INTERIOR SPACE FOR RECEIVING A GASLIQUID MIXTURE THROUGH SAID OPENING WHEREBY SAID MIXTURE

Claim 3

The invention set forth in claim 1 together with: conduit means extending through said bottom part to the interior of said baffle formed by said bottom part and said side wall of said baffle, said conduit means extending downwardly from said bottom part for draining liquid from the interior of said baffle.

Claim 4

A receiver-separator tank for a liquid injected gas compressor system comprising: an elongated tank portion forming a first compartment and comprising a liquid reservoir; a conduit extending into said tank portion for conducting a gas-liquid mixture into said first compartment; a section of said tank comprising a vertically disposed cylindrical tower the interior of which forms a second compartment, said tower including a side wall extending into said elongated tank portion; a partition between said first and second compartments formed by a transverse plate formed across the lower end of said tower and in said elongated tank portion; an opening in said plate for admitting a gas-liquid mixture to said second compartment; an outlet conduit disposed on the side wall of said tower section above said elongated tank portion and connected to said second compartment. liquid separator means comprising an element having a porous wall structure and disposed in said second compartment in such a way that said mixture flows through said opening and then through said element for separation of liquid from said mixture whereby substantially liquid free gas then exits said second compartment through said outlet conduit; a head closing the end of said tower opposite said lower end, said head being removably attached to said tower for providing access to said element for removal of said element from said tower; and a baffle including a bottom part disposed in spaced apart relationship with respect to said plate and below said plate, said baffle including a side wall extending around said bottom part and upwardly from said bottom part, said baffle being positioned with respect to said opening in said plate so as to require substantially a reversal in flow direction of the gas-liquid mixture passing from said first compartment to said second compartment.

Claim 5

A receiver-separator tank for a liquid injected gas compressor system comprising: an elongated tank portion forming a first compartment and comprising a liquid reservoir; a conduit extending into said tank portion for conducting a gas-liquid mixture into said first compartment; a section of said tank comprising a vertically disposed cylindrical tower the interior of which forms a second compartment, said tower including a side wall extending into said elongated tank portion; a partition between said first and second compartments formed by a transverse plate formed across the lower end of said tower and in said elongated tank portion; an opening in said plate for admitting a gas-liquid mixture to said second compartment; an outlet conduit disposed on the side wall of said tower section above said elongated tank portion and connected to said second compartment. liquid separator means comprising an element having a porous wall structure and disposed in said second compartment in such a way that said mixture flows through said opening and then through said element for separation of liquid from said mixture whereby substantially liquid free gas then exits said second compartment through said outlet conduit; a head closing the end of said tower opposite said lower end, said head being removably attached to said tower for providing access to said element for removal of said element from said tower; and a baffle including a bottom part disposed in spaced apart relationship with respect to said plate and below said plate, said baffle including a side wall extending around said bottom part and upwardly from said bottom part, said baffle being positioned with respect to said opening in said plate so as to require substantially a reversal in flow direction of the gas-liquid mixture passing from said first compartment to said second compartment.
