AIR-CLEANING APPARATUS.-
Application filed April 5, 1923, Serial No. 630,024. Renewed July 29, 1926.
. tures of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from. the following description.
In the accompanying drawings illustrating the preferred form of the invention Fig. 1
7 represents an elevation largely. in section of an apparatus embodying the features of the invention, and Fig. 2 is a detail illustrating a section of the mechanism for spraying a liquid into the air.
According to the present invention the a1r to be cleansedis initially impregnated with a spray of cleansing liquid, such as water, which serves to dissolve or precipitate solids and gases from the air. Thereafter the liquid containing the solids or dissolved'gases is completely separated from the air by a. re-
and a1r without the employment of small volving screen which permits the air to pass freely therethrough while removing the liquid therefrom through contact with the 20 id portions of the traveling screen surace. intermin 1e with the air by a rotary atomizing cup om the peripheral edge of which a spray, of liquid is delivered. This liq uid spray issues from. the atomizing cup in a thin sheet and intimately mingles with the body of air, serving to wash out impurities. After treatment w1th the cleansing liquid, the air passes through a chamber of suflicient length to ermit the atomized liquid to thoroughly mtermingle. therewith and wash out impurities and subsequently encounters the revolving screen separator which removes the liquid from the air in a simple and eflicient manner.
Referring to the-illustrated embodiment of the invention, the air washing chamber indicated at 10 'is provided at one end with an air intake duct 12 of smaller size in which The liquid is conveniently caused to.
is located the liquid spray mechanism 14.
-The opposite) end of the air washing chamber is provided with a revolving separator '16 which may be mounted upon the fan shaft 18. The circulation of air through the chamber may be accomplished by an exhaust blower indicated generally at 20 and mounted upon the shaft 18, this blower being driven by a drive pulley 22 actuated in any suitable manner (not shown).
The liquid for cleansing the air which may be hot or cold water or an alkaline oracid solution is intermixed with the air through a rotary atomizing cup 24 having outwardly flaring funnel shaped walls 26 communicating with a feed pipe 28 passing through the interior of the cup. The cup isprovided with an extended sleeve portion 30 journaled for rotationin an outer bearing 32, which in turn is supported within the casing 10 through a skeleton support 34;. The feed pipe 28 passes through a longitudinal bore formed in the interior of the sleeve 30 and permittingthe latter to revolve freely about the pipe. With this construction, liquid. passing. through the pipe under suitable pressure is delivered to the surface 26 and after passage thereover is discharged centrifugally from the peripheral edge 36 in a conicaLstream, as indicated generally by dot and dash lines. This construction provides for an intimate intermixture of the liquid orifices or similar constructions which are easily clogged and liable to derangement. It will be evident that with this construction a quantity of liquid is sprayed in excess. of the amount which the air can 'absorb or cause to evaporate, the surplus water washing out theimpurlties and being thereafter separated. Theatomizing cup may be conveniently rotated throu h the use of a series, of fan blades 40 extendmg radially from the outer portion of the cup andlocatedin-th path-of the air drawn through the comparatively small intake 12. This incoming draft of air is of'sufficient force to rotate the cup and nozzle at high speed and provide for the necessary atomizing and spraying of the liquid. If the current of air is not suflicient to rotate the cup at the desired speed under certain conditions of operation, external driving connections may be provided for the purpose of positively rotating the cup.
The air mixed with an excess of liquid recess.
separation of the liquid and foreign matter but permitting a relatively free passage of air therethrough. To this end, as indicated,
-a flat screen 16 is mounted at its periphery upon a spider 50 having a hub 52 secured to the fan shaft 18. The spider is provided at its periphery with an annular rim portion 54 to which the edge of the screen is secured. The peripheral portion of the screen travels in an annular recess 56 formed in the casing and serving to collect and. discharge the dirty liquidinto apipe 58 communicating with the bottom portion of the As will be evident to those skilled in the art, the liquid impinges upon the solid portion of the screen and is thrown therefrom by centrifugal force into the recess passing downwardly about the annular recess and outwardly through the pipe 58. Not only is the liquid separated from the air through the use of this screen but in addition solid matter which may not have been washed out by the liquid is also engaged and separated from the air through the rotation of the screen. The mesh of 4 the screen and its speed of rotation are portions of the revolving screen. In addition the screen may be driven independently of the fan and at a different speed.
WVhile it is preferred to employ the'specific construction and arrangement of parts shown and described it will be understood that this construction and arrangement is separator located at the opposite end of the chamber and designed to remove entrained liquid and impurities trom the a1r, and
means beyond the screen separator for causing a movement of air and liquid through the chamber.
2. Air cleaning apparatus comprisingan elongated settling chamber having a reduced intake portion, a rotary atomizing cup journaled for rotation within the intake, means for supplying liquid to the atomizing cup, a rotary screen separator posltioned at the opposite end of the chamber and located and designed to cause substantially all of the air to pass therethrough removing liquid and impurities therefrom, and means located beyond the screen separatort'or causing a flow of air and liquid through the chamber.
