Abstract

A device for mixing gases with a liquid carried in an elongated vertical vessel for creating a large mass of small bubbles which rise upwardly within the liquid to be absorbed thereby. The device can be readily disassembled for cleaning, and has a filter medium therein which minimizes clogging of the diffusing main body.

Claims

1. In a device for mixing gases with a liquid comprising an elongated vertical vessel having a bottom therein adapted to be filled with said liquid with which said gas is to be mixed, a pressurized source of gas, a first concave disc-shaped member carried adjacent the bottom of said vessel facing upwardly, a second concave disc-shaped member complementary in size and shape with said first concave member carried in overlying relationship and facing said first concave member, a threaded fitting carried by said first concave member extending upwardly, a threaded coupling carried by said second concave disc-shaped member engaging said threaded fitting for drawing said second concave disc-shaped member closely adjacent said first concave discshaped member for defining a cavity therebetween, seal means interposed between the peripheral edges of said first and second concave members, said second concave member having a porous body, tubular means extending between said pressurized source of gas and said threaded coupling for conveying gas from said pressurized source of gas into said cavity formed by said concave members, said gas being forced through said porous body into said liquid carried in said vessel creating a large volume of gas bubbles for being mixed with said liquid and any foreign matter entering said vessel through said tubular means is collected in said cavity, said threaded coupling having a bore extending therethrough, said threaded fitting having a bore therein with one end communicating with said bore extending through said coupling and another end terminating in said cavity for conveying gas to a lower portion of said cavity, a filter medium carried in said cavity between said another end of said bore and said second concave member for preventing foreign matter from reaching said porous body, and said first concave member being capable of being separated from said second concave member by disengaging said threaded coupling from said fitting for allowing access to said cavity for cleaning.

2. The device as set forth in claim 1, wherein said porous body of said second concave member is constructed of sintered stainless steel.

3. The device as set forth in claim 1, wherein said seal means has an enlarged head against which said peripheral edges of said first and second concave members are carried, and a pair of opposed beads carried by said seal means for engaging said first and second concave members for providing a positive seal therebetween.
