serial no. 540,578.

To all whom 'it may concern:

Be it known that l, CARL llTnonsoi-rnmr,

engineer, a citizen of the German Empire,

purifier and some of which are used for introducing the gas to and the others for dis-v charging it from the purifier,

wing to this arrangement, the thickness of the layers of purifying material through which the gas to be purified has to pass, can be varied. Alt the same time it. 1s possible to make puriiiers of any desired output, as the gasto be purified has merely to travel fromits supplyy pipe to the discharge pipes which are adjoining it, so that apparatus of any desired height may he built.

A simple construction easy to attend, is obtained by. branching ofi" the different gas supply conduits from a single chamber and also making the mouth pieces of the outlet conduits to open into a single collecting chamber.

Y In order to insure uniformity of action in the various portions of the apparatus with such an arrangement of a number of gas conduits, the cooperation of which in one 'and the same-apparatus corresponds to a number of purifiers arranged side-by side, it is advisable to provide the different gas supply conduits with indicator devices which indicate the gas liow in thel conduits.

This can effected in a simple manner byl arranging m the conduits, ad3ustable throttle valves and connecting them to indicating devices operated by the pressure in front of, and behind, the throttle valves. As the quantity of gas passing through the conduit for a given size of cross-section passage arca left free by the throttle valve, depends on the diiference in the pressures in front of, and behind, the throttle valves, it is in that way possible to control accurately the working of the apparatus in all its parts.

Ait is advisable to maire the gas pipes in the apparatus of louver-like members arranged in a roof-like formation, tho roof surfaces-of which are perforated in such manner that on the one hand they are used as supports for the purifying mass, while on the other hand they allow the gas to pass. The louvers can be arranged in an adjustable manner so that, by a suitable movement of the same, support can be withdrawn from i the purifying mass when it is desired to discharge it from the apparatus.

A purifying apparatus constructed in accordance with the above principles, isA illustrated by way of example in the accompanying drawing. f f.

Figure l is la vertical section through the purifier, i11"'the;-directiQn transversely of the gas conduits. Fig. 2 is a portion of the purifier, partly in section and partly in side elevation, in the direction parallel to the gas conduits, and Fig. 3 is a diagrammatic view of the regulating' and indicator" device for different pipes, branching off from a single supply.

The purifier chamber is surrounded on all sides with Walls. The two front walls which are at a right angle to the gas conduits arranged in the purifier, are formed into double Walls. The purilier walls at the gas inlet side, are marked l, 2, While the walls at the outlet side, are marked 3, 4. The walls 2, 4, form supports for a number of girders 5 which, in their turn, support the louvers. The louvers pass through the purifier chamber from one Wall to the other and are distributed as uinformly as possible in the said space. The louvers which afford support to the purifying mass, form canallike hollow spaces in the interior of the purification mass, which hollow spaces form iues for the gas. vThe louvers are divided into two groups, one group 6 forming with the supporting plates 7 the supply conduit for the gas, and the other group 8 forming with the Support plates 9 outlet conduits for the gas. The louvers are pivoted at their upper ends to projections of the girders 5,

`while the bottom ends are pivoted by links the rods 12 on the drawing at 14. The vii-ders 14 as well as the girders corresponding to the rods 13, are held in the raised position by a supporting device consisting of cams 15 rotatably mounted ou the girders 14, in connection with the abutlnents 16 secured to the apparatus. The rotatable cams 15 are provided with

eyes

17, 18 in order to release at will the rods 12 or 13 in their raised position, so as to enable them to fall down into the lower position, or so as to secure them in their raisedposition.

The lower end oit' the apparatus is provided with corneal outlet branches 19 for the purifying mass, which are held closed by means of lids 2() with closing brackets 2l.

in the construction of the purifier illustrated in the drawing, it has been assumed thatthere is a cellar or pit under the chamber of the purifier, so that transport trucks can be brought in the cellar or pit under the openings ot the outlet hoppers 19, for the purpose of receiving the pnried mass. For filling thc trucks traveling hoppers could be :ulvantageously used, with an oscillating bottom closing device, suoli as indicated in liig. 1 ot the drawing at 22. (iras is admitted into the intermediate space between the wa'lls l and 2. From thesaid space. openings 23 lead to thc hollow spaces under the louvers t3. 'lhrottle valves 2t are 'used for closing the openings 2li to a greater or smaller extent. 'lhe gas outlets leading 'from the hollow spaces under the louvers 8, to the intermediate space between the walls Si, i, arel marked Q5. v The working of the purifying device is as followst-Before the purifier is started, it is filled with the purifying mass. which can be effected from a floor situated above the purifier. rihe purifier is filled with the mass in such manner that under each of the louvers t3, 7 is left a. conduit-shaped hollow space, the shape of which on the lower surface is determined by the angle of slope of thc material. After the apparatus has been filled. gas is admitted into the space between the walls l, Q. l'he gas passing through the openings 23 in the wall 2, spreads among the various conduits closed bythe louve-rs (i. iy suitably adjusting or setting the slide valves J-l, the admission of gas to the conduits corresponding to the louvers (i, can be regulated. ll`rom the inlet conduits arranged under the louvers t, the gas passes through the intermediate spaces between the.

su i )ortjine surfaces 7. into the )uritfinfY t* n l mass, and vpenetrates through the layer of' the mass situated between the supply conduit, and the outlet' conduits arrangedV all around and closed by the.'louversv The arrows in Fig. l of the drawing indicate the path ot' the gas. From the outlet eonduits situated under the louvers 8. the purified gas passes through the openings 25 in the wall 4, into the space between the walls `l .and 3, and is carried away from that, point. The layer of the purifying mass, through which the gas is to pass, can be made any desired thickness. A thickness of layer ot about t300 nini. has been found by the applicant to be very suitable.

When it is desired to empty the purifier, the rods 1Q, 13 are moved from their raised position into the lower position, which, as regards the vrods 12, is effected, according to the drawing, by raising the eyes 17 and subsequent lowering of the rods. The rotatable supporting plates 15 then slide away from the abutnients 16, so that the system of rods 12 can sink. the louvers assuming a position such as that 'shown in the drawing t'or a group of louvers t. Owing to such a rotation or turning of the lonvers, all support is withdrawn from the purifying inass, so that when the closing devices 21 are, opened, the purifying mass is freely discharged through the outlet cones 15).

Fig. 3 shows a device for a more accurate control ofi' the flow in the Various gas supply conduits. It will be seen here, as in Fig. 2, that there are provided adjustable throttling valves QG, 16h. 2G mounted in the supply conduits 2T, 2T", 2T arranged side` by side. Branch conduits 2811, Q9 lead from the pipes 2T in trout ot'. and behind` the throttling valvesgti, to a ditterentiatpressure gage devic'e 3U". indicates in a well known manner, the currents in the pipe. sections 27u. lalculation shows that if the cross-sectional area of passage left tree by the throttle valve, be indicated by F. the quantity of gas passing through the pipe by V, the difference of pressures in front of. and behind, the throttle valve by It and a constant by C, then 2C G I1.` lf F is fixed as a function of /l in a table for a given V, it is possible, without difiieulty and special trainino', t0 adjust the passage ot' gas, in accor(` ance with the indications of the pressure measuring devices` to the desired extent.
