blade is turned over, as shown at 12, to form collector, and an outlet 14 for the gas is pro, vided beyondthe last recrement-collector of 1 the series. Between outlet 14 and the last 'firs't recrement-collector, and the recrement in said gas is thereby thoroughly Wetted. .The particles of recrement in the gas after of the path of the stream of gas flowing through the apparatus. The gas will leave 35 mal tothe blades and move. across the wash-v ing-faces 21 0f the members 8, which will be .surfaces 22 of members 8, which extend a a receptacle adapted to collect the recrement An inlet 13 admits the gas in front of the first recrementmember 8 toward the outlet an exhaustin fan 15 is carried by shaft 6. Water s a mitted to the interior of the cas ng by means formed hollow and provided with outlets 17, situated in front of the recrement-collectors, whereby, if desired, water may be admitted to the interior of the housing throu h this The gas'entering inlet 13 comes in contact with the Water-spray formed by deliveringwater from pipe 16 against the blades of the being1 wetted, and thereb increased in wei t, contact With .the aces19 of the bla es, and as the shaft is'rotatedat'a high bent-over portions 12', and these bent-over portions will guide and direct the particles so that they will be thrown by centrifugal force beyond the edge 20 of themembcrs 8 and out the recrement-collectors substantially normaintained. in a wet'condition by the water admitted. Theseradially disposed portions of members 8, besides acting as Washing-surfaces, serve to correct the angularity of the gas leaving the cpllector-blades and direct it in pro 'er'm anne'r t o the next succeeding series o collector-blades. The gas which is thrown off radially by centrifugal force from back toward the center of theapparatus by means of curved short'distance'inwardly for that purpose. In order; to precludethe possibility of any renary typeofproducer, a plurality of series of these collectors and washers are employed, and in order to take away the work of building up w [res'sure from the collectors, if the same isesired, the exhauster 15 is employed.

The member 8, adjacent to the 'exhauster. has its curved portion 22 extended farther in toward the'center of the device-than the preceding merhbers in order to direct the gas to T e recrement which is thrown out -onto the inner surface of the casing by the cen-' trifugal action of the collectors will flow down the casing to the water contained in receptacle 7 and with said water will pass out of the apparatus. It will, be seen that each of the members 8 isprovided with a portion 23,

extending downwardly below the surface of the water in receptacle 7, whereby the water in the receptacle acts as a seal for each of the portions of the apparatus partitioned off by the members 8.

It will be seen thatwith this a paratus in operation the ammonia contained in the gas from the fact that it is brought into intimate relation-with the finely-divided water in the apparatus will be absorbed therebyand pass out with the water through theoutlet to receptacle 7, and, if desired, this ammonia may be utilized as is now common.

It will be understood that the pitch of the collector-blades may be varied, and, if desired, the exhauster may be omitted and the blades utilized to build up the desired pressure, or the pitch may be so changed that the exhauster will do all of the work of propelling the gas through the apparatus.

A pulley 24 for driving the apparatus isillustrated; but it will be understood that the same may be driven from anysu'itable source of ower and by any desired means.
