Definitions

  • the invention relates to a device for separating gases from water-bearing systems, in particular heating systems.
  • the formation of gas cushions is often observed after some time, which can impair and even interrupt the water circuit, especially in higher radiators, as well as in places with slower flow.
  • the gas cushion formation reduces the circulation in the higher floors compared to the lower ones, which in many cases leads to higher flow temperatures being set in ignorance of the relationships in order to provide sufficient heating output in the higher floors make sure. This further promotes the formation of gas cushions.
  • the thermal efficiency of the entire system continues to decrease.
  • a known device of this type consists of a float housing with a ventilation opening in the housing cover which can be closed by a sealing member controlled by a float and a bottom opening which is delimited by an outwardly projecting cylindrical housing collar. It contains the actual valve with float, sealing element, actuator and two concentric channel systems, which have the task of continuously venting the associated water circuit automatically and without delay and without delay according to the amount of air generated during operation. (DE-PS 22 35 161).
  • the object of the invention is to provide an uncomplicated and high-efficiency device for separating gases from water-carrying systems, in particular heating systems. Movable parts are to be avoided.
  • the new device is also said to be largely insensitive to contamination from dirt particles, such as rust particles etc., which are inevitably carried in a heating water circuit.
  • the device is designed as a chamber having a vertical spatial axis and provided with vertical inlet and outlet connections and flowing through from bottom to top, in the interior of which an axially incident gas separation body is arranged.
  • a separator is advantageously obtained which has no moving parts, can be installed in risers and advantageously takes advantage of the inertia of the air bubbles and dirt particles to improve the separation efficiency.
  • the walls of the chamber form different flow cross-sections, which are initially expanded starting from the inlet nozzle and, preferably after a relatively short transition, in the area of the largest cross-section towards the outlet nozzle, again flow into a preferably funnel-shaped taper and that a catch bell is arranged in the area of the chamber which is expanded in this way and has an opening which is directed against the flow and which opens at its upper end into a venting duct leading to the outside, which has a gas outlet valve outside the chamber.
  • the flow cross section for the liquid in the lower region of the chamber is at least partially smaller than the cross section of the inlet connection. This advantageously results in the formation of expansion air bubbles. The deposition efficiency can be further improved in this way.
  • the chamber is a body formed by at least partially rotationally symmetrical walls with inlet and outlet connections arranged approximately in the axis of symmetry.
  • the advantage of this configuration is that a low-resistance flow system is created in this way, which does not significantly impede or adversely affect the circulation of the water. It is also advantageous that an inexpensive manufacture of the chamber is possible.
  • the ventilation channel is led out obliquely upwards out of the chamber and carries the catch bell at its lower end. In this way, a very uncomplicated configuration is achieved, which facilitates the manufacture of the device and thus influences the manufacturing costs very favorably.
  • the catch bell has a plate designed as a gas separation body, which is preferably flat and horizontal is trained.
  • the plate is a porous metal part, such as a fine-mesh screen fabric, metal cloth, sintered metal, metal wool or the like. is.
  • Such metal parts and materials, including brass, are commercially available and can be processed without difficulty.
  • the plate can also be a porous plastic part, which has the advantage that such material is completely immune to corrosion.
  • the catch bell is at least partially filled with gas-permeable material such as glass wool, glass wool, rock wool, stainless steel wool, granular free-flowing ceramic bodies, coarsely classified sand etc. and with a sieve cloth or the like. is closed.
  • gas-permeable material such as glass wool, glass wool, rock wool, stainless steel wool, granular free-flowing ceramic bodies, coarsely classified sand etc. and with a sieve cloth or the like. is closed.
  • gas-permeable material such as glass wool, glass wool, rock wool, stainless steel wool, granular free-flowing ceramic bodies, coarsely classified sand etc. and with a sieve cloth or the like.
  • the vertically flowed through chamber is at least partially cylindrical and forms a one-piece casting with the collecting bell and the ventilation duct.
  • the opening diameter of the collecting bell corresponds approximately to the inner thread diameter of the inlet connection. This results in an optimum between the size of the collecting bell and the possibility of manufacture.
  • annular space with parallel walls is formed between the wall of the vertically flowed through chamber and the collecting bell on the side opposite the ventilation duct. This results in a particularly favorable routing of the heating water flow with the smallest chamber dimensions.
  • the device according to the invention consists of the vertically arranged chamber 1, which in its lower area 4 has an inlet connection 2 for connection to the pipeline of the heating circuit, as well as an outlet connection 3 for further piping of the heating circuit in its upper area .
  • the chamber 1 has in its lower part 4 a funnel-shaped extension, which is followed by a transition 5 with an almost unchanged cross-sectional area, which merges in the flow direction into a funnel-shaped, conical taper 6, at the end of which the outlet connection 3 is attached.
  • the catch bell 7, which here has the shape of a funnel 8, which preferably projects into the region of the transition 5 of the chamber 1 with its downwardly open end 9.
  • the outlet channel 11 which has a ventilation line 12 which is led out of the chamber 1 at an angle and close to the side of the outlet connection 3.
  • the line 12 ends in a vertical end piece 13 with a connecting sleeve with an internal thread 14, into which a gas outlet 15, for example a vent valve of any type, is screwed in a gas-tight manner.
  • the outlet channel 11 advantageously simply carries the collecting bell 7. This is optionally closed in the region of its opening 9 with a membrane-like, gas-permeable gas collecting plate 16 which is made of a porous material for the passage of gas bubbles.
  • the gas trap plate 16 can also be made concave, as is shown by the lines 16 'indicated by dashed lines.
  • the concave design of the plate 16 advantageously favors the capture and collection of the gas bubbles 19.
  • FIG. 2 shows a further advantageous embodiment of the device.
  • the liquid has to pass through zones of different pressures and speeds in succession between the concentric gas collecting rings 16 "', 16" “, 16” “' on the underside of the actual gas collecting device 16". This also advantageously results in considerable relaxation of air bubbles. The newly formed bubbles are then separated in the subsequent calmed zones.
