Definitions

  • the invention relates to a metering device for introducing an additive into a main liquid stream circulating in a pipe, which device comprises a reciprocating differential piston pump for withdrawing the additive from a container and dosing it, this pump having a first inlet for receiving a main liquid flow which drives the pump, a second inlet for withdrawing the additive and an outlet for the admixture of additive and main liquid.
  • EP 0 255 791 relates to a dosing device of the kind defined above wherein an adjustment of the dose drawn and then injected is provided by moving a jacket along a tube to adjust the length of the suction stroke of the piston.
  • FR 740 179 relates to a Venturi ejector according to which is sucked at the neck of the Venturi a fluid which mixes with a fluid fluid relaxing in the convergent.
  • the driving fluid may be a liquid, especially water, while the aspirated fluid may be air in the case of a water jet vacuum ejector.
  • the dosage of the fluid sucked into the mixture of fluid and aspirated fluid is not taken into consideration.
  • the range of dosages is limited especially for obtaining very small dosages, for example of the order of parts per million (ppm).
  • the volumes of additive to be injected at each cycle of the pump then become very small and can not be obtained by a simple mechanical system.
  • WO 02/02938 proposes a device that allows small dosages.
  • this device uses periodic electric control means and solenoid valves, which complicates the installation and increases the cost.
  • the object of the invention is, above all, to provide a dosing device which makes it possible in a simple and economical way to process high flow rates of main liquid with pumps of reduced dimensions and to increase the permitted range of dosages, in particular to small dosages.
  • a metering device for introducing an additive into a main liquid stream flowing in a pipe, this device comprising a reciprocating differential piston pump for withdrawing the additive into a container and dosing it, this pump comprising a first inlet for receiving a main liquid flow which drives the pump, a second inlet for withdrawing the additive and an outlet for the admixture of additive and main liquid, is characterized in that it comprises a venturi arranged in the pipe and in that the pump is connected in parallel with the venturi, the first inlet of the pump being connected to the inlet of the venturi while the outlet of the pump is connected to the neck of the venturi.
  • the geometry of the venturi is adjusted to the pressure drop of the pump between first inlet and outlet, to allow a substantially constant dosage to be obtained despite flow variations, and independent of the inlet pressure.
  • the geometry of the venturi can be adjusted to establish in operation a pressure difference of about 1.5 bar and less than 2 bar between the inlet pressure and the pressure at the neck.
  • the geometry of the venturi can be adjusted so that the pressure drop created by the venturi is less than 0.5 bar.
  • An additional pressure drop can be created in the bypass circuit of the pump, in particular by a nozzle, in particular adjustable, preferably disposed at the outlet of the pump.
  • the venturi can be set so that the ratio R is at least ten, or close to ten. Large flows can therefore be treated by smaller pumps.
  • the ratio R may be greater than one hundred.
  • the pump may be provided to allow a volume ratio between injected additive flow and engine liquid flow through the pump less than or equal to one thousandth (1/1000) while the volume dilution of the mixture exiting the pump in the main flow
  • the venturi crossing is less than one percent (1%) so that the volume dosage in the main flow is less than or equal to 10 -5 or 10 ppm (10 parts per million).
  • venturi and the pump form a together, and connection means are provided at the inlet and the outlet of the venturi for insertion and connection to two sections of the pipe.
  • a dosing device D for introducing a liquid additive A in a main liquid stream L, water in the example in question.
  • the liquid additive A is contained in a container 1.
  • Device D comprises a metering pump 2 arranged with its vertical axis.
  • the pump 2 is of a known type, in particular manufactured and marketed by the applicant company DOSATRON INTERNATIONAL. An example of such pumps is described in EP 1 151 196 or US 6,684,753 .
  • the pump 2 comprises a reciprocating differential piston 3 which drives a piston 4 of smaller diameter, ensuring the pumping and injection of the additive A.
  • the piston 4 slides in a chamber cylindrical auxiliary pump 5 connected by a sampling tube 6 to the container 1.
  • the tube 6 immersed in the additive to be taken.
  • the pump 2 comprises a first inlet 7 for receiving a flow of main liquid, generally water, which drives the differential piston 3.
  • the pump 2 comprises a second inlet 8 located at the bottom of the auxiliary pump body 5 for the removal of the additive A, and an outlet 9 for the mixture of additive A and main liquid L.
  • Device D comprises a venturi 10 which has an inlet section 11, a neck 12 of reduced section and an outlet section 13.
  • the pump 2 is connected in parallel with the venturi 10, the first inlet 7 of the pump being connected by a pipe 14 to the inlet 11 of the venturi while the outlet 9 of the pump is connected by a pipe 15 to the neck 12 of the venturi .
  • the cross sections of the different parts of the venturi are preferably circular, but could have a different shape, for example rectangular.
  • the pressure difference (Pe -Pc) between the inlet and the neck of the venturi is related to the geometry (section variation) and the flow rate Qe of liquid.
  • a variation of the inlet pressure shifts the operating range of the venturi, the range of which decreases as the inlet pressure increases.
  • the pressure difference between the inlet 11 and the neck 12 of the venturi is adjusted to the pressure drop between the inlet 7 and the outlet 9 specific to the pump in normal operation.
  • this pressure drop can be of the order of 1.5 bar and remains less than 2 bar.
  • venturi The geometry of the venturi is designed to create a reduced pressure drop, less than 0.5 bar, between inlet and outlet of the venturi.
  • the venturi 10 and the pump 2 may form an assembly, and connection means Re and Rs are provided at the inlet and the outlet of the venturi for insertion and connection to two sections of the pipe Te, Ts.
  • the derivative flow which passes through the pipe 14 and into the pump 2 allows the operation of the metering pump between the inlet pressure Pe of the venturi 10 and the pressure Pc at the neck.
  • the venturi 10 is set so that the ratio R of the flow rate Qe passing through the venturi 10 to the flow rate Qd passing through the metering pump 2 is at least equal to 10 (ten).
  • the main flow does not pass into the metering pump 2.
  • This allows the use of a small pump 2 for dosing an additive product A in a large flow of main liquid.
  • a standard pump of maximum flow 2.5 m 3 / h ensuring a dosage of 10%.
  • the invention thus makes it possible to treat large flows of main liquid with relatively small dosing pumps.
  • the ratio R to ensure small dosages can be at least 100 (one hundred).
  • a metering pump 2 allowing a volume ratio between flow rate of additive A injected and flow rate Qd of engine liquid passing through the pump equal to one thousandth (1/1000), combined with a dilution of at least one percent (1%) allows a volume dosage of additive A in the main flow rate Qe less than 10 -5 , ie 10 ppm (10 parts per million).
  • FIG. 3 illustrates an additional possibility of adjusting the flow rate of the pump by creating an additional pressure drop in the circuit derived from the pump.
  • this pressure drop is created by a nozzle 16 installed at the outlet 9 of the pump.
  • the nozzle 16 has a calibrated through hole.
  • the pump 2, in the absence of any nozzle 16 generally allows a flow rate adjustment between a maximum value M and a minimum value M / p, with p close to three, for example.
  • the adjustment range is increased towards the lower values, according to the diameter of the calibrated orifice of the nozzle.
  • the nozzle 16 may be adjustable, in particular by means of a needle, which makes it possible to vary the dosage, in particular particularly in the case of a dosing pump which has no adjustment.
  • At least two different nozzles can be provided, mounted in parallel on one or more by-passes, with one or more selection valves, which makes it possible to obtain at least two dosing ranges.
  • venturi and metering pump allows a pressure independent operating range. This combination also makes it possible to obtain a substantially constant dosage and not simply an injection that would vary as a function of pressure and flow rate variations.
  • the invention makes it possible to overcome the pressure limitation of the venturi.
