- APPARATUS FOR ENRI CHING AND PUBIIFYING GAS.

Application filed. November 13, 1922. Serial No. 600,777.

In certain districts where gasis used for lighting and cooking purposes, it is found that at certain times there is a very poor pressure in the supply main, and the chief object of our invention is to devise apparatus by means of which an enriching liquid may be mixed with the gas and burned therewith in order that greater heat may be obtained and thus make up to a large extent for the low pressure in the main.

A further object in devising the apparatus is to obtain a very intimate mixture of the gas and enriching liquid in order that a very cheap grade of the latter might be used, and which would therefore render it cheaper to use less gas and inore enriching liquid. A further objectis to arrange the apparatus so that it may be used for the purification of gas and particularly natural gas.

We attainour object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which--- I Fig.1 is a vertical section through our improvedapparatus Fig. 2 a horizontal section on the line 2-2 on Fig. '1; I s b v Fig. 3- a'view similar to Fig. 1. but partly broken away showing a modification, and

Fig. 4 a sectional detail showing'the indicating float and filling inlet.

In the drawings like-numerals of reference indicate corresponding parts in the different figures.

. Our'device comprises mainly a closed casimr'. which is formed in two. sections. the lowersection 1 forming the container for the enriching liquid and the upper section or cover 2 supporting the mixing apparatus. The two parts willbe secured torrether in anv suitable manner andthe'joint made tight. r A

4 In one'si'de of the upper-section 2 is an outlet 4 for the mixture. At the inlet side of the upper section 2 is secured the partition 5 forming a small compartment 6 in f ont of the inlet 3. At the opposite sideof the upper section 2 is secured the partition inlet 3Iandinthe onposite'sid'e thereof igthe' to the screen.

end of a tubular member 10, which member has a float 11 secured to its other end. The hinged end of the member 10 will be'connected with the partition 5 with a. suitable flexible material 12 so that no as can pass into the main compartment without passing through the tubular member 10. This tubular member will be provided with an. opening 13 in its lower side adjacent the float 11, and at the side of this opening remote from the float is hingedly secured, a flap 14 for the purpose which will hereinafter appear; In the partition 7 in front of the outlet 4.is' formed an opening and in this opening is secured a fine gauge or screen 79 The device is used as follows. The main from the meter is connected with the inlet 3 and the service main connected with the outlet 4. The gas enters through the inlet 3 and is directed into the end of the tubular; member 10, down which it passes and out through the opening 13 where it strikes the 1 surface of the enriching liquid in the section 1 and takes up a certain amount of the latter. In order to assist this mixing of the gas and enriching liquid, the interior of the tubular member is preferably restricted in d iameter towards-the outlet in order to increase the speed with which the gas strikes the surface of the enriching liquid. The mixture of gas and enriching liquid then passes up through the screen 15 and into the compartment 8 from whence it passes through the outlet 4. The screen 15 is for the urpose of giving the gas and the enriching liquid which has been picked up thereby the final intimate mixing, and also ensures a more uniform mixture at all times as any excess of enriching liquid is caught by the screen and any gas which has not taken up .a proper quantity of enriching liquid will pick up a further supply asit passes through the enriching liquid clinging As the enriching liquid is used, the member 10 and float 11 move downwardly, and as the flap 14 always tends to hang straight down, the gas emerging from the opening 13 is always directed into the surface of the enriching liquid. 1 w

The lower section 1 of the casing. it ,will be noted, is formed as substantially the seg-} ment of a cylinder. This is particularly advantageous, when the level of the enriching Too ' wardl liquid is low, in directing gas upwardly after it has been in contact with the enriching liquid.

In order that it may be ascertained whether a fresh supply of enriching liquid is required, I provide the float 17, the stem 16 of whichis adapted to slide through an opening 18 formed in the cover 2. In order that no gas may escape through the opening 13, the float 17 will normally be forced down into the enriching liquid and held there by a suitable cap closing the opening. (See Fi .4.

is variation the partition 5 might be omitted as shown in Fig. 3 and the tubular member might be wholly or partially flexible and secured directly to the inlet 3.

As a further variation, the partition 7 might be dispensed withand the screen 15 placed directly in the outlet 4. The con struction shown in Fig. 1 is, however, preferable, as in the compartment 8 is always available a supply of the mixture. The placing of the screen 15 at an angle as shown is also of advantage as any dirt striking it is not so likely to stick and clog the same.

When the apparatus is to be used for gas purifying urposes, the enriching liquid may be draine out and a suitable purifying liquid inserted instead. The apparatus will then operate in the same manner as for enriching the as. A suitabTe inlet 19 will be provided through which a fresh supply of enriching liqlu id maybe inserted.

or enriching purposes, we may, for example, 'use liquid methane, gasoline or any of the gas enriching oils as used at gas lants, while for purifying purposes the 'quid used will depend on the result to be obtained.

From vthe construction described it will be seen that we have devised apparatus which will satisfactorily attain the objects of our invention as set out in the specificatron.

What we claim as our invention 1s 1. An apparatus for enriching or purify-' ing gas, the combination of a liquid containing'casing having a gas inlet and a mixture outlet, said inlet and outlet being positioned above the highest liquid level of said container; a movable tubular member having one end adapted to receive gas entering through the inlet; said member having an opening therein adapted to direct gas downfloat or said member adapted to hold the openmg spaced from the surface of the liquid to permit passage at all times of the gas to the outlet without travel through the on to the surface of thefliquid; a

liquid; and a swinging flap secured to the movable member at the side of said opening nearest the inlet, and adapted to assist in directing the gasas it leaves the opening against the surface of the liquid while still permitting the gas to travel to the mixture outlet without passing through the liquid.

2. In apparatus for enriching or purifying gas, the combination of a liquid containing casing having a gas inlet and a mixture outlet, said inlet and outlet being positioned above the highest liquid level of said container; a partition forming a separate compartment adjacent the inlet opening; a partition forming a separate compartment adjacent the outlet opening, each of said partitions having an opening therein; a tubular member hingedly connected at one end in the openin of the first mentioned partition;

a float on the other end of said tubular mem-' ber, said member having an opening in its under side adjacent the float, adapted to di-- .rect the gas downwardly on to the surface of the liquid, said float being adapted to hold the opening spaced from the surface of the liquid to permit assage at all times of gas to the outlet wit out passage through the liquid; and a screen in the opening of the second mentioned partition.

3. In apparatus for enriching or purifying gas, the combination of a liquid containing casin having a gas inlet and a mixture outlet, said inlet and outlet'being positioned above the highest liquid level of said con? tainer, a tubular member having one end hingedly connected and adapted to receive gas from said inlet opening; a float on the free end of said tubular member, said member having an opening in its under side adj acent the float adapted to direct gas mainly downwardly on to the surface of the liquid and, said float being adapted to hold the opening spaced from the surface of the liquid to permit assage at all times of gas to the outlet wit out passage through the liquid, said tubular member having at all times a downward inclination throughout its length from its hinged end to the float end to prevent trapping of the gas by condensation; and aswinging flap secured to the side of said opening nearest the inlet and adapted to assist in directing the gas as it leaves the o ening against the surface of the liquid, whi e still permitting the 4 gas to travel to the mixture outlet without passin through the liquid.
