Hansen, Muskegon, Michf Application JuneV `11, 1 954, seal No. 436,050 4 claims.V (ci. 10s-11a) Y 'his invention relates to rav water and oil degasifying we 1 The main objects of the invention are:

First, to provide a' well structure which while simple is very eicient in removing gas from ground liquid, commonly water or'oil, as itis pumped from the well.

Second, to provide a Well structure having this advantage which is not likely to become inoperative from use over a long period oftime or require replacement ofpa'rts.y Y l Objects'relating to details and economies of the invention will appearfrom the description to follow. The invention` is defined and pointed out inthe claims.

Preferred embodiments of the invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a view in vertical section of a well embodying my invention, certain parts being shown `in full lines and mainlyconventionally.

Fig. 2 is an enlarged fragmentary View in vertical section on a line corresponding to the section of Fig. 1, falll ing water being conventionally illustrated as drops.

Fig. 3 is an enlarged fragmentary view partially in sectionon a line corresponding to line3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary view partially in vertical section illustrating the relation `of the motor to other parts.

Fig. 5 is an enlarged fragmentary view mainly in vertical section of a second form of my invention in which an air lift is used to increase the liquid level in the casing above that of the normal ground level.

Fig. 6 is an enlarged fragmentary view partially in vertical section of the lower end of the embodiment shown in Fig. 5.

It will be understood that no attempt has been made to show the parts in their relative proportions and that these are or may be considerable varied `in practice. Various parts are shown conventionally as the structure thereof will b e readily understood.

In the accompanying drawing, 1 represents the ground and 2 a tubular well casing sunk therein. This well casing is sunk below water level so that a substantial depth of ground water stands within the casing as is indicated at 3, in Figs. 2 and 3. lt will be understood that that water level illustrated relative to the surface of the ground is merely for the purpose of illustration.

In this embodiment the pump discharge column or water delivery pipe 5 is provided with a series of impeller housings 6. The motor is conventionally shown at 7. The water discharge is indicated at 8. The impeller shaft is shown at 18 but the impellers are not illustrated.

In spaced concentric relation within the casing I mount a gas separator tube or sleeve 9. A substantial length of this sleeve should be surrounded by the ground water or oil as is indicated in Fig. 2. The sleeve 9 is closed at its lower end 10 and the discharge column or water discharge pipe 5 is concentrically located with the extension 19 opening to the lower end of the sleeve.

2,833,222 Patented May 6, 1958 The casingr 2 is providedI with a screen conventionally indicated at 11. `The sleeve has a gas exhaust or outlet'A 12 provided with'a suction pump 13 which producesa partial vacuum within the sleeve and exhaustsv or draws the gas therefrom. To facilitate the separation of the vgas from the water or oil the sleeve is provided with ver# tically spaced annular groups of nozzles 14, the nozzles opening to the casing and discharging radially inward.

The nozzles of thegroups are angularly spaced, as 'is sprayed and broken up, asindicated by the drops 17,y conventionally shown in Fig.`2, so that any remaining' gas escapes therefrom. The gas is drawn off or escapes from the top of the degasifying sleeve. The partial vacuum resulting from the gas suction pump 13 renders the well somewhat more elicient than when gas is allowedto escape through a' vent opening. The partial vacuum in the casing increases the flow of liquid through the nozzles and the force with which it impinges the impingement member 15.

The embodiment of my invention shown in Figs. 5 and 6 is wellV adapted for use in conditions where the ground level depth of water or oil is not suicient to ll the casing to the desired or vefficient working level. In mostpsoil yconditions if the level of the .liquid to be pumped falls the well can be sunk to the desired depth; however, certain conditions render that impractical and in such conditionsl provide a so-called air lift 20 which is disposed atthe' lower end ofthe sleeve 9 and is in the form of a perforated cylinder or head` connectedby` charged through the nozzles 14 as the result of gravity and also as the result of the partial vacuum in the sleeve 9, forceably against the impingement or splash members 15 which breaks the liquid up into a spray. The liquid falls in the form of drops indicated at 17 upon the impact plate below, the liquid from the upper impact plates successively falling upon the lower which keeps the liquid in broken up or drop condition and greatly facilitates the escape of gas therefrom which is drawn off by the suction pump 13.

l have illustrated and described my invention in a commercial embodiment, the parts, however, being shown without regard to exact proportions in view of the fact that a portion may be varied and the parts are shown in susbtantially reduced size. However, it is believed that the disclosure made will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention, what is claimed as new and is desired'to be secured by Letters Patent is:
