3 Claims. (Cl. 137-132) This invention concerns a device for automatically injecting chemical additives into industrial equipment such as oil wells, gas wells, water wells, pipe lines, gasoline plant flow lines and refinery flow lines. The additives may include corrosion inhibitors, emulsion breakers, defoamers, lubricants, and other industrial chemicals.
The invention, in brief, comprises a cylindrical vessel; an outlet conduit extending through the bottom of the vessel, a syphon having the shorter end positioned within the vessel and the longer end positioned in the outlet conduit, an inlet conduit extending through the sidewall of the vessel arranged at an angle of about 30 to 45 degrees to the radius of the tank at the point of entrance of the inlet conduit, a flushing liquid source connected to the inlet conduit, means arranged on the inlet conduit adapted to intermittently supply flushing liquid to the inlet conduit and means adapted to continuously supply liquid additive to the inlet conduit.
One object of this invention is to provide apparatus for injecting liquid additive automatically in batches into desired equipment.
Another object of this invention is to provide thorough wash action during the additive injection.
These and other objects of this invention will be under stood from the description taken with reference to the drawing wherein:
Fig. 1 is an elevational view of the apparatus of the invention; and
Fig. 2 is a view taken on lines 2-2 of Fig. 1.
Referring to the drawing in greater detail:
In Figs. 1 and 2 is shown a vessel or tank provided with a removable cover 11 screw threadedly connected thereto; the cover 11 being formed to provide a vent or bleed opening 12. An outlet or discharge conduit 13 is positioned in tank 10 and extends through the lower end thereof. As seen clearly in Fig. 2, conduit 13 is preferably positioned in the center of tank 10 and it extends to the upper portion of tank 10. An inverted U-shaped syphon 14 is provided and arranged such that end 15 of the shorter leg is positioned adjacent the bottom of tank 10 and end 16 of the longer leg extends below tank 10 in outlet conduit 13.
An inlet conduit 17 extends through the wall of tank 10 and fluidly communicates with a source of flushing liquid. A solenoid operated valve 18 is arranged in conduit 17. This valve is actuated by a timing arrangement such as a clock, not shown, and is adapted to periodically close off flow of additive through conduit 17. Such valves are known and may be suitably of construction such as shown and described in General Controls Company, Chicago, 111., Catalog 536, p. 67. A chemical additive feeder conduit 20 fluidly communicates with conduit 17 between solenoid valve 18 and the connection of conduit 17 to tank 10. A chemical additive feeder 19, which may be suitably a pump and reservoir is connected to conduit 20 and is adapted to supply a chemical additive to tank 10. The conduit 17, as clearly seen in Fig. 2, connects through the wall of tank 10 at an angle of 2,884,942 Patented May 5, 1959 ICC about 30 to 45 degrees to the radius of the tank 10 at the point of entrance of conduit 17 (indicated by the dashed lines). The lower end of conduit outlet 13 may be connected to any type equipment into which it is desired to inject a chemical additive.
In operation the chemical feeder 19 supplies additive continuously to tank 10 via conduits 20 and 17. The additive collects in tank 10. At selected or predetermined times, solenoid valve 18 opens by means of a time clock or other suitable device, not shown, and flushing liquid flows through conduit 17 into tank 10.
The angular position of inlet conduit 17 causes the flushing liquid to travel generally tangentially thereby effecting a more complete flushing or washing action in tank 10. The flushing liquid causes the additive collected in tank 10 to overflow through the center outlet 13. Thus, the additive is batched into a well or other equipment. In addition, the additive is given a thorough washing into the receptacle equipment by means of a relatively large volume of flushing liquid. At another selected or predetermined time solenoid valve 18 closes by means of the time clock or other timing means and the flow of flushing liquid is terminated. However, the syphon, which is already operating because of the initial overflow of the flushing liquid into outlet conduit 13 continues to operate until the level of the liquid in tank 10 is below end 15 of syphon 14, as shown in Fig. 1. After the syphon is broken, the additive again is collected in the quantity desired and the cycle is repeated.
T o assure satisfactory operation, one only has to supply additive to feeder 19 at proper intervals.
The term liquid or additive as used herein means substantially a liquid phase with or without gaseous or solid phases or both solid and gaseous phases.
Having fully described the nature, objects and operation of the invention, we claim:
1. A device adapted to automatically inject corrosion inhibitor chemical additive intermittently into equipment subject to corrosion comprising a cylindrical tank, a vertically arranged outlet conduit extending through the center of the bottom of said tank to substantially adjacent the top of said tank, an inverted U-shaped syphon conduit having the shorter end positioned adjacent the bottom of said tank and having the longer end positioned in said outlet conduit and extending below the bottom of said tank, the U-shaped portion being arranged adjacent the upper end of said outlet conduit, an inlet conduit extending through the side wall of said tank adjacent the bottom thereof and arranged angularly to the radius of the tank at the point of entrance of the inlet conduit, timed valve means positioned on said inlet conduit adapted to intermittently supply flushing fluid to said tank and a corrosion inhibitor additive feeder connected to said inlet conduit between said tank and said valve means adapted to continuously feed additive to said tank.
2. Apparatus adapted to automatically inject corrosion inhibitor chemical additive intermittently into equipment subject to corrosion utilizing a cylindrical tank, a vertically arranged outlet conduit extending through the center of the bottom of said tank to substantially adjacent the top of said tank, an inverted U-shaped syphon conduit having the shorter end positioned adjacent the bottom of said tank and having the longer end positioned in said outlet conduit and extending below the bottom of said tank, the intermediate portion thereof extending to adjacent the top of said outlet conduit comprising an inlet conduit extending through the side wall of said tank adjacent the bottom thereof and arranged angularly to the radius of the tank at the point of entrance of the inlet conduit, timed valve means positioned on said inlet conduit adapted to inter mittently supply flushing fluid to said tank and a corrosion inhibitor additive feeder connected to said inlet conduit between said tank and said valve means adapted to continuously feed additive to said tank.
