Definitions

  • the box For the purpose of rendering the rates of flow of the liquid streams uniform, the box comprises a mass of synthetic foam or like material having open cells whereby it is possible to achieve an excellent separation of the gas or steam bubbles from the liquid notwithstanding the particularly low price of the box.
  • the present invention relates to devices for removing gas from a liquid flowing in a conduit or pipe, this conduit being for example a part of the cooling circuit of an internal combustion engine.
  • An object of the present invention is to provide a gas removing box which is particularly efficient and yet simple in construction and cheap.
  • the invention provides a box comprising an inlet conduit for the liquid containing the gas and an outlet conduit for the liquid from which gas has been removed, and baffle means interposed between the conduits, wherein said baffle means comprise a mass of a material which has a tridimensional reticulated structure, two free opposed faces and affords throughout its mass a network of intercommunicating cavities which form between the free faces sinuous passages none of which constitutes a preferential passage.
  • This material may be for example a synthetic foam known per se similar to the foam employed in particular in fuel tanks toreduce explosion hazards; a wad of knitted synthetic filament similar to scouring wads employed by housewives or a block constituted by evenly-distributed synthetic fibres without preferential orientation and interconnected by a binder such as a thermosetting resin which coats each of the fibres and connects them at their'points of contact.
  • a synthetic foam known per se similar to the foam employed in particular in fuel tanks toreduce explosion hazards
  • a wad of knitted synthetic filament similar to scouring wads employed by housewives or a block constituted by evenly-distributed synthetic fibres without preferential orientation and interconnected by a binder such as a thermosetting resin which coats each of the fibres and connects them at their'points of contact.
  • the percentage of cavities must exceed 90 percent and be preferably between 95 and 98 percent and the average dimension of the cavities must be of the order of 2-5 mm.
  • FIGURE showing a sectional view of a gas-removing box according to the invention.
  • a gas-removing box can be placed of course in any liquid circuit from which it is desired to remove gas in an efficient manner, for example in the cooling circuit of an internal combustion engine.
  • the body of the box comprises two portions 1 and 2 which are interconnected in a fluidtight manner by screws 3.
  • a sealing element or gasket 4 is preferably interposed between these two portions.
  • An inlet conduit 5 and an outlet conduit 6 communicate with the interior of the box.
  • the latter is provided in its upper part with a plug 7 having a calibrated valve of known type which maintains the internal pressure between two predetermined limits.
  • the centre part of the inside of the box is filled with a block or mass 8 of a material having a tridimensional reticulated structure which defines in the box two chambers 9 and 10 with which communicate respectively the conduit .5 supplying the liquid emulsion and the conduit 6 discharging the gas-free liquid.
  • mass 8 There may be employed for constructing the mass 8 for example:
  • Fknitted synthetic filament constituting a wad similar to the wads employed by housewives for scouring plates and saucepans;
  • a binder such as a thermosetting resimwhich interconnects them in the region of their points of contact and produces a coherent assembly.
  • This device operates in a very simple manner
  • the liquid containing bubbles of gas which arrives by way of the conduit 5 must pass right through the mass 8 before escaping by way of the conduit 6. Owing to the very highnumber of intercommunicating cavities that this liquid must pass through, the liquid flows in a very sinuous path andany rapidmovement is calmed or braked so that the gas or steam bubbles have time to rise to the surface, with theresult that the stream of liquid which reaches the outlet conduit 6 is free of gas.
  • the mass of foam or other material disposed in the gas-removing box constitutes a filter capable of arresting solid. bodies in suspension in the liquid, which constitutes a further advantage.
  • the block can moreover be replaced periodically very cheaply owing to the cheapness of the material and the simplicity of the operation.
  • the shape of the box is not critical, the essential feature being that the chambers 9 and 10 be completely separated by the mass of foam or other material with no preferential passage through which a part of the liquid might flow at higher speed and draw along the gas bubbles to the outlet conduit.
  • the nature of the material employed in the construction of the mass depends on the characteristics of the liquid to be treated, it being understood that this material must be perfectly inert with respect to the liquid with which it is constantly in contact.
  • a device combined with a liquid circuit for removing gas from the liquid flowing in the circuit, said device comprising means defining a box, an inlet conduit connected to an upstream part of said circuit and an outlet conduit connected to a downstream part of said circuit, which conduits communicate with the interior of the box and are disposed adjacent opposite ends of said box, the box being arranged to conduct liquid therethrough in a substantially horizontal direction,
  • the baffle means comprising a mass of a material which extends fully across the box in a generally vertical plane so as to engage the top bottom and side inner walls of the box transversely of the horizontal direction of flow of said liquid and has a tridimensional reticulated structure which defines throughout the mass of the material interconnecting macroscopic cavities which form sinuous throughway passages in said mass, which passages extend in substantially all directions in said mass, none of which passages constitute a preferential passage, the percentage of said cavities in said mass being more than 90 percent, the mass being arranged to allow passage of liquid substantially horizontally from said inlet conduit to said outlet conduit while causing gas bubbles to rise vertically therewithin and transversely from said liquid, and gas outlet means positioned at an upper portion of said box for discharging such risen gas from the box.
  • a device as claimed in claim 1, wherein said box comprises two portions and means detachably interconnecting said portions so as to allow access to and replacement of said mass of material.
  • a device as claimed in claim 1, wherein the average size of the cavities is substantially 25 mm.
  • a device as claimed in claim 1, wherein said mass is constituted by substantially uniformly distributed synthetic fibres having no preferential orientation and a binder which coats each one of said fibres and interconnects said fibres at points of contact therebetween.
