Definitions

  • This invention relates to apparatus forcontrolling the rate of flow of gases and particularly to apparatus for 'ensuu.'.'u .a slow but regular rate of flow of a such as chlorine employed for the purification of water.
  • the object of my invention is to produce a simple and reliable apparatus which shall give results with a suflicient degree of accuracy tor the saidpurpose, which shall have parts and in which adjustment of the rate of flow can be readily efiecte'd.
  • the invention comprises the combination,
  • the invention further comprises the arrangement of the siphon with a divergent delivery portion having an air or gas vent hole therein adjacent to or at the entrance to the divergent pa
  • the invention further comprises the ar. rangement of a spreading. device for liquid which the gas from the said vessel travels for the purposeof dissolving or absorbing the gas.
  • Figure 1 is an elevation partlyin section of an apparatus constructed in one convenmy invention.
  • Figure 2 is a detail view 0 right angles tothe Figure 1 position.
  • Figure 3 is an elevation partly in section showing a modified form of apparatus.
  • Figure 4 is a sectional view (in-the line .4- -4 of Figure 3.-
  • the liquid is adapted lift system-"for raising- 1929, Serial No. 382,823, and in Great Britain September 1a, 1928.
  • the tube terminating in a diverging portion f and having a small aperture g therethrough adjacent to or at the entrance of the divergent part.
  • the cup, or vessel d has apertures h therein at its upper end for the delivery of the gas.
  • the lower end of the tube 6 up which the gas and liquid risein alternate plugs has a bell 2' thereon at the. lower end immersed in the liquid.
  • the vessel 0 contains a'liquid which in the case of the proportioning of chlorine gas may be concentrated sulphuric acid.
  • the gas under a slight head or pressure is delivered into the liquid column in Y the tube 1).
  • the liquid is raised in b by the gas in the known manner and overflows into the cup d, and after a predetermined level has been reached in the latter, it siphons back to the main body of liquid by way of the siphon tube 6.
  • the small hole 9 which is open to air or gas. ensures the complete clearanceof liquid from the tube when the siphoning is completed.
  • the gas flows out of the vessel (1 into the vessel 0 and through to where it is required.
  • the rate of delivery of gas can be 7 controlling the liquid cycles regulated by in the cup or vessel d by varying the inlet gas pressure.
  • the gas enters. y the tube a and acts to lift liquid up the tube b to the vessel (1 with the siphon tube e thereon.
  • the gas leaving the vessel d ⁇ by the pipe is enters a vessel m into which liquid to dissolve the gas is sprayed'through a nozzle 11. on to a disc 0 whereby it is spread in a thin. film to fill the vessel m.
  • the liquid leaves m b the pipe pand passes through the vessel 0 w ich receives the delivery from the siphon e, to the outlet branch g.
  • the tube 1- on the vessel cacts to prevent the formation of a vacuous condition in such vessel 4 by admitting air thereto.
  • a method of ascertaining and re lating the rate of delivery of a gas consisting in utilizing said the manner of an air lift pump measuring the number of times a predetermined quantity of the liquid is raised by the gas in any predeterminated interval of time and collecting the gas used in raising the liquid and which separates from the latter.
  • An apparatus for measured rate with a tube up delivering a gas at a comprising the combination which liquid is raised by the gas for raising a liquid in comprising, in combination,a liquid and gas receiving vessel, a siphon upon said vessel for emptym the said vessel intermittently, a
  • second vesse receiving. the liquid from the siphon a tube connecting the second vessel to the first mentioned vessel, means injecting the gas into the liquid in said tubewhereby gas which separates from the elevated liquid, means injecting liquid into said gas to absorb the same, and an air venting and a liquid overflow connection to said. second vessel.
  • a tube having an enlarged part and leading from the to of the vessel with the siphon thereon to said means into which the liquid siphons, and a liquid inlet nozzle and liquid spreader the enlarged part of the said tube to effect the absorption by the spread liquid of the gas delivered into said tube.
  • An apparatus for use in ascertaimng and regulating the rate of delivery of a gas comprising, in combination, an outer vessel having a gas outlet, an inner vessel having a gas outlet in the top thereof, a tube extending up into said innervessel from the lower part of said outer vessel, a gas inlet gh said outer vessel into the said tube leading up into the inner vessel, and a siphon upon said inner vessel emptying the contents thereof when they reach a predetermined height into the outer vessel.
