Definitions
- the invention relates to a degassing device, in particular a ventilation device for a central heating system.
- a ventilation device is known from NL-A-8603021, in which a Device is shown, comprising a housing in which a prechamber is arranged, which has a tangential aligned inlet connection to an upper part of a upright cylindrical chamber connects.
- the Antechamber is connected to a line system of a CV connectable, with the cylindrical chamber below with a drain is provided, which also to the Line system is connectable.
- To vent get Water over the pre-chamber in the venting device into it, flows up in it, then becomes directed horizontally and tangentially into the over the inlet guided cylindrical chamber.
- the water flows in this Chamber down helically along the wall and leaves the chamber over the drain. At the rotation the water creates a so-called cyclone effect, wherein Air bubbles in the water towards the center of the chamber shift and then move upwards out of the chamber a vent float provided in the top of the chamber to escape.
- a disadvantage of this known device is that the Ventilation is still in need of improvement and that the Pressure drop over it is relatively high.
- the construction with the antechamber has bends, in which flow losses arise.
- the device is for simultaneous connection to multiple channels unsuitable, it also comes to flow losses, if several channels merged into a channel.
- a lot of pressure drop means that a strong pump is needed or more Pumping capacity is necessary to achieve the desired To achieve water throughput.
- the device not or poorly able to stand still Water flow the air bubbles over the vent float dissipate to the environment.
- the present invention aims to be the above to at least partially eliminate these disadvantages and to provide a viable alternative.
- Especially the object of the invention is a degassing device to provide that in small dimensions and Low pressure drop bring about a good degassing can.
- the device comprises here a housing with a substantially vertical aligned, cylindrical chamber with at least two essentially tangentially oriented inlets and a sequence for connection to a line system, as well a bleed valve to remove gases from the housing dissipate.
- the feeds are destined to be one Flow channel of the conduit system in fluid communication with stand or be brought.
- the feeds provide during operation for an eccentric inflow of Liquid. This creates a cyclone, where Gases from the liquid in the center of the chamber relocate.
- the gases can then over the Degassing shut-off valve from the fluid circuit be dissipated. This is therefore with the advantage connected, that at least two substantially tangential in a degassing chamber oriented incoming Liquid flows at a low pressure drop and a very good degassing to a drainage channel can be merged.
- the feeds open in essentially the same height in the chamber.
- the one is in an angle of substantially 90 degrees twisted along the wall circumference of the chamber with respect to the other inlet intended. This also creates the effect of several incoming liquids that are fine mix together and a common cyclone form. At the same time this structure makes the arrangement of Degassing device in a construction with two under a substantially vertical angle with respect each other standing inlet channels possible without while unnecessary pressure losses occur.
- the object according to the invention can at the same time by a Degassing device according to claim 4 achieved become.
- the device comprises a housing with a substantially vertically oriented, cylindrical chamber with at least one substantially tangentially oriented inlet and a drain for Connection to a pipe system and a Degassing valve to remove gases from the housing dissipate.
- the inflows and outflows are determined, with and drains of the conduit system in fluid communication to stand or to be brought.
- the process is in essentially aligned axially and closes on the lower end of the chamber. This will be advantageous a low pressure drop in the degassing device achieved, in particular by the lower end of the Chamber gradually tapered in diameter, which in the process goes over.
- substantially axial aligned process can be at a standstill or slow liquid flow gas bubbles undisturbed ascend through the chamber and over the degassing valve escape.
- the degassing device can thereby both during the transport of the liquid through as well as at temporary standstill of Degas the liquid well and efficiently, which is one more thing better degassing effect causes.
- the process can also be essentially be aligned tangentially and to the peripheral wall of the Connect the chamber.
- Advantage of the eccentric process is this is a slight pressure drop.
- the invention also relates to a complex of a Degassing device with a heat exchanger after a of claims 10-12 and a heating system according to claim 13th
- the device in its entirety with the reference numeral 1 indicated.
- the device comprises a Housing 2, in which an upright, cylindrical Chamber 3 is arranged.
- At the chamber 3 are two horizontal feeds 4, 5 connected, each one Inlet flows into an inflow, which tangentially (eccentric with respect to the central central axis) in the chamber 3 is aligned.
- the feeds 4, 5 are at an angle of 90 degrees with respect to each other, extend along the same side of the Center axis of the chamber and are located on the same Height.
- the feeds 4, 5 are intended to a Line system to be connected through which during operation, water or another fluid Heating medium with a different temperature is transported.
- the lower end of the chamber 3 is flattened cone-shaped executed, the cone in a vertical sequence 6 passes.
- the process 6 begins with an outflow part, which is substantially axial is aligned and essentially in the extension the central center axis of the cylindrical chamber 3 lies.
- an automatic working degassing 8 is provided at the top of the chamber 3 .
- a hand degasifier be provided at the top of the chamber 3 .
- the degasser 8 is located substantially upright above the drain 6.
- a Flow partition wall 9 At the top of the chamber 3 below the degasser 8 is a Flow partition wall 9.
- the transported in circulation flows Heating medium over the two inlets with a specified Speed eccentric into the chamber 3 inside.
- the both liquid streams are directed around the left and reinforce each other.
- the gases that are in the liquid in particular air, are hereby in the middle of the Driven by three-turns.
- the gases can escape from the Center of the chamber 3 to the top of the chamber. 3 shift to then automatically or manually to be discharged via the degasser 8 to the environment.
- the thus freed of gases liquid leaves the Chamber 3 at the bottom over the drain 6.
- the cone ensures a gradual termination of the Liquid flow to the pressure drop there too minimize.
- the flow dividing wall 9 ensures that the Gases separated from the liquid in the Chamber 3 can come to rest, the deposition of liquid and gas remains.
- FIGs 2-5 show a complex of one Heat exchanger 10 a central heating system with a Variant of the degassing apparatus 1 described above.
- the heat exchanger 10 comprises a housing 11 in which a Part of a conduit system 12 (see Figure 3) arranged is that can be heated with the help of flue gases, when burning a gas in a burner, which may be provided in the housing 11, be released.
- the conduit system 12 is here partially installed in the walls of the housing 11.
- the Walls of the housing 11 may be made of aluminum, for example be made.
- the piping system includes a Inlet mouthpiece 13, which in a meandering channel 14th merges with curved pieces and straight pipe parts.
- the channel 14 shares at the top of the Heat exchanger in two, after which the liquid in Parallel flow through channels 18, 19 flows in a Front and rear wall of the housing 11 are installed. These channels 18, 19 form cooling channels around the uppermost To cool wall parts of the housing 11 of the heat exchanger.
- the cooling channels 18, 19 open into the respective inlets 4, 5 of the degassing device 1.
- the process 6 of Degassing device 1 connects to a connection mouthpiece 21 of the conduit system 12 at.
- the housing 2 of the degassing device 1 is here in a particular one-piece running side wall 22 of the Housing 11 installed, wherein the degassing device 1 is provided at an angle of the side wall (see FIG. 4).
- the inner wall structure of the side wall 22 is in the two cross sections of the figures 5a and b to see, in which two mutually connectable side wall parts 22a, 22b are shown.
- nearby a vertically erected Flow partition 24a now at the same time with an im Cross-section of continuous, inwardly extending Boundary edge 24b is provided. This can be more advantageous Way during the production of the housing 11th be poured and also serves the gases above to rest in the chamber and without Liquid to escape through the degasser 8.
- more than two Inlets with associated, substantially tangential aligned inflow can be provided and can the inflows at other positions in relation to each other be provided.
- the feeds and / or the Inflow parts of it if possible different be positioned, for example, if possible also be aligned at an angle to each other.
