GUSTAV AMINOFF, OF BALTIMORE, MARYLAND.

' ABSORPTION APPARATUS.

To all whom it may concern:

Be it known that I, GUSTAV AMINOFF, citizen of the Grand Duchy of Finland, residing at Baltimore. Maryland. have invented certain new and useful Improvements in Absorption 1-\pparatus. of which the following is a specification.

My invention relates to apparatus of that class in which liquids and gases are brought into contact, whereby gas is absorbed by the liquid either to purify the gas, or to impregnate the liquid,

My invention herein explained operates .by simultaneous passage of gas and liquid in opposite directions, as in the well known apparatus in which a series of'bottles is used, the bottles being connected by pipes.

My said invention comprises a chute steeply inclined, and closed at sides and bottom forming a liquid and gas passageway, with a series of boxesformed by partitions set in the upper part, but not extending to the bottom.

It is illustrated in the accompanying drawings, in which- Figure 1 shows a longitudinal vertical section of the apparatus; and Fig. 2 a section on line 2-2 of Fig. 1, seen from be- -n eath. v

The main part ofmy absorber or washer is indicated at B. This consists of a steeply inclined chute or tube having top, bottom and sides forming a channel for the passage of the gas and liquid. The upper partof this chute is subdivided into boxes 5 by partitions 4, extending from side to side and -from the top halfway, more or less, toward the bottom (3 of the chute. This construction, and the inclination, form a series of closely set boxes, in which portions of the liquid are held and exposed to the action of the gas.

At the upper end 01'' the chute is a tank 8, into which water is fed from a supply pipe 7. The bottom of this tank inclined, and the tank is separated from the gas exit pipe by a wall 9, at the bottom of which is an opening through which the liquid may pass underneath the gas exit pipe, over a shoulder 17, and through a passage 10 into the upper end of the chute. just; below its end wall. The passage pipe 10 'is made in two parts held separably together at. the flanges .20. The lower end of the chute is also closed, and an overflow ipe 12 for the liquid is set in this lower end: and provided with a dis- Specification of Letters Patent."

Application filed January 13, 1911. Serial No. 602,487.

charge branch, set at a properpoint in height, in relation to the tank 8,'to maintain the liquid in the boxes of the chute. A drain pipe and faucet are indicated at 21. Above the pipe 12, and below the series of boxes, at gas supply pipe 13 is connected with the chute.

At the ,upper end of the chute is a gas exit pipe 16, the lower end of which opens into.

the liquid passage from the tank to the. chute, so that the gas, rising therein, can

esca e from the liquid and rise in the pipe.

Ba es, as shown in Fig. 1, are set, preferably inclined, in the pipe 16, to throw back the spray.

As it is found desirable to occasionally remove the bottom 6 for cleaning thisbottom is held to the chute removably by suitable clamps 7, using packings between the parts;

It will be observed that there is a clearpassage for the liquid beneath the lower edges of the partition walls which form the boxes, and ,above the bottom of the chute. The heightof the discharge of. the liquid and thereby its surface in the tank 8 is adjusted to secure the amount 'of hydrostatic pressure necessary to force the liquid against the resistance of the reverse gas current and through the overflow pipe. The partition 9, therefore, affords a seal against the escape of the gas into the reservoir 8, and thus the flow of the liquid is automatic while the inflow is sealed from the gas. The apparatus being thus properly adjusted, the gas will occupy the boxes while the liquid rises from the clear passage and presses upon it in the boxes while the outward flowing gas rises, flowing over the lower edgesof the partitions and from ne box into the other. The pipe 12 for the automatic overflow of liquid may be omitted, and the outflow may be 3.1 lowed to take place through the faucet 21, this faucet being regulated to properly check the flow or liquid, and hold back suiticient for the purpose above indicated.

The combined feed box and gas discharge, with the seal, are detachable as a. whole from the chute by means of the flange joint at 20. I am also making the absorption chute wider at the gas inlet end and narrower at the gas outlet, thus providing more absorbing capacity where the volume of gas is largest, and less where the gas has been partly absorbed and reduced in volume. These proportions may be reversed in special uses of the apparatus where the relations of the gas and the liquid require it. This variation in the ca ac1ty at the ends of the chute is illustrated 1n Fig. 2. Also the spaces in the chute between the compartments and the bottom may advantageously be made progressively deeper from the lower to the upper end. The proportions of the construction are varied with the varying pressure of the incoming. and outgoing gas. The lower the pressure of the outgoing gasthe lower will be the liquid in the feed box. If the gas is underpartial vacuum, the construction must be such as to permit theliquid level to sink accordingly in the feed box without breakiugthe hydrostatic seal. If the incoming as is .at or below atmospheric pressure, the

' iquid outflow is accordingly lowered.

This absorber may also be used when it suits the purpose without constant reverse act-ion between the gas and the liquid. The liquid maybe stationary or maybe fed and drawn-to many points by means of'gooseneck pipes, which provide seals of liquid against the escape of gas.

Itiwill be apparent that the apparatus may be used to wash the liquid by the gas or the reverse. It is made of any suitable material, such as soft orhard lead, iron, earthenware, or wo'od,es-the material used 7 may require. 7

I claim as my invention substantially as herein described:

1. An absorption apparatus comprising an inclined closed chute consisting of aseries of contiguous boxes'in its upper part, and a bottom completing the liquid passage under-' neath said passage communicating-with the and means for introducing gas at the lowei and discharging the same-at the upper end 2. In an absorber, an inclined closed chute consisting of a series of upper open boxes, 21 bottom completing the liquid passage, an open feed box or reservoir, :1. liquid supply therefor, seals to prevent the escape of gas a discharge for liquid at the lower end 01 the chute, and means for passing the"gas in a direction opposite to the fiow of tl1( liquid. 3. The described absorber comprising ar inclined closed chute havinga series of boxes means for feeding the liquid and discharging the gas at the upper end of said chute a gas inlet pipe set near the lower end 01 the series of boxes of said absorber, and a liquid overflow pipe set in the lower end 01 said chute and below the gas inlet pipe. whereby a body of liquid is led between the gas inlet and the liquid discharge,'and a gas seal formed.-

4. In the described absorber, the open feed box 8, connected to the chute by a detachable joint 20, said chute having an inclined bottom and a series of-boxes, a gas. discharge pipe 16, set between the chute and the feed box, and a partition 9 extendin near to the said bottom and forming a seaE 5. In the described absorber, an inclined chute having a series of boxes, and means for i'mtrpduc-ing and discharging reverse currentsof liquid and gas, the chute varying in width along the courseaiof the same to accommodate a changing volume of gas.

In testimony whereof, I- atlix my signature in presence of two witnesses.
