Description

The The invention relates to an air and dirt separator for the water technology - in particular a micro bubble and Air and sludge and dirt separators for sanitary and heating technology.

in the Water - even in closed systems - are located Physically conditioned air and other gases and where there is water and gases in metal piping, find corrosion processes instead, focusing on the functionality of the components negative impact on a water treatment plant. Gases in the system water cause circulation problems and corrosion products - like entrained mud particles.

• a) Luft ist im Wasser gelöst
• b) Luft ist im Wasser in Form von Luftbläschen vorhanden.

There are two types of air in water systems

• a) Air is dissolved in the water
• b) Air is present in the water in the form of air bubbles.

To a) Water is capable - depending on Pressure and temperature - air in its individual gases oxygen, To absorb nitrogen and traces of other gases. This solution from water and gases is relatively stable. With the filling a heating system with a water volume of 100 liters at one Temperature of 10 ° C and a pressure of 2 bar are approx. 7% air in dissolved form introduced into the system. at Heating the water by 65 ° reduces the proportion of air in the water to about 3%, that means by the heating process about 4 l of gases of 100 l of water be released from the system liquid.

• – sichtbare große Luftblasen
• – wenig sichtbare bis kaum auszumachende Mikroblasen.

To b) Free air in the system water in the form of gas bubbles may be

• - visible large air bubbles
• - little visible to barely visible micro bubbles.

larger Air bubbles develop higher buoyancy forces than small bubbles and move predominantly in the upper Area of the pipeline through the system. The smaller the bubbles - Microbubbles have a diameter of 0.01 mm ... 0.2 mm - the stronger is their inclination, in the flow to remain. In certain states behave Microbubbles in the flow as the flow and sit down no longer off. Following is the removal of microbubbles with conventional facilities such as fast or automatic or Float ventilators, air pots and / or centrifugal separators not possible; these devices work well after plant maintenance during plant filling and emptying processes.

microbubbles arise in different ways, such. B. at the temperature peaks the firebox wall in a boiler, which is above the boiling point of water, with a size of about 0.05 mm ... 0.13 mm diameter. Due to the throttling effect at cross-sectional constrictions - like for valves - the fluids experience pressure drops, which extend into the vacuum area. Air bubbles are reached when the physically caused solubility limit free, flow rate <0.1 m / s. By the pressure drop will be present in the flow of air bubbles larger and shatter to microbubbles after the cross-sectional constriction by a sudden pressure rise up to the system pressure - in The literature also referred to as cavitation as in the Hohlsogbildung at the blade channel entrance of pump impellers.

Of the Gas content in liquids is due to temperature and pressure change certainly; since the values for temperature and pressure are in constantly changing a heating system, fluctuates also the physically related gas solubility limit and thus the content of free and dissolved gases. microbubble essentially contribute to free gas bubbles - like under b) - to remove in the volume flow. As mentioned above, it comes in the range of temperature peaks of the boiler fire room wall to outgassing in the form of microbubbles over the volume flow get into the heating flow. Are the micro bubbles in the boiler flow out removed from the system before it is in solution again in the pipe network go, the water is again able to return to a certain Gas quantity record. So is part of the system liquid in Pipe network in a state related to gas absorptive and takes the remaining free gases in the system. As by the Water circulation the process during operation of the system constantly repeated, the microbubble volume decreases continuously until no free gas bubbles are more contained in the liquid; Corrosion is avoided, circulatory disturbances due to eliminated by trapped air bubbles. Physically conditioned The principle works flawlessly as in the area of one- and two-family houses up to a height of about 15 m and a pressure of about 2 bar. In addition, compression degassers are to be used.

• – beim Zusetzen der Filter erfolgt Druckaufbau
• – Filterelemente müssen bereitgestellt werden, wartungsintensiv
• – Filterwechsel mittels By-pass-Strecke oder Anlagenabschaltung.

The formation of sludge in the water systems is a consequence of the reactive oxygen contained in the water; the oxygen is looking for binding partners, such as. B. in steel pipe systems of iron on the pipe wall. The result is sludge as a corrosion product that damages plant components and reduces the heat transfer to heating surfaces. Removal of the sludge is possible by filtering or sedimentation. When filtering, even with several water cycles in a circle running systems achieved quickly defined separation efficiency; However, this advantage outweighs a number of disadvantages, such as

• - When adding the filter, pressure builds up
• - Filter elements must be provided, maintenance-intensive
• - Filter change by bypass pass or shutdown.

• – kein Druckaufbau durch Zusetzen
• – keine Bereitstellung von Auswechsel-/Ersatzteilen
• – Entleerung unter Betriebsdruck ohne Unterbrechung möglich.

For the sedimentation sludge separators are used; Mud separators are usually cylindrical, cross-flow devices with a drainable drainage receptacle below the water flow - desiccant dehumidifiers, the flow of water being affected by internals, as within the housing, downward turbulence zones through which debris is swirled and at the bottom of the housing stop for emptying. Advantages of the sludge separator

• - no pressure build-up due to clogging
• - no provision of replacement / spare parts
• - Draining under operating pressure without interruption possible.

With Help of magnetism can add to the water cycle removed the magnetic flux conductive dirt particles become.

in the The following will be the prior art of air and dirt separators for water technology - especially microbubble and air and sludge and dirt separators for the sanitary and Heating technology appreciated; according to the Prior art, depending on the application, a variety of Types of air and dirt traps for water technology - in particular a micro bubble and air and sludge and dirt traps for sanitary and heating technology in use.

By the European patent application EP 2 116 727 an air separator for a submersible pump is presented with an input side arranged rotating impeller with an at least partially directed in the axial direction outlet. For submersible pumps, it may be necessary to precede the actual pump stages with an air separator in order to separate air or gases contained in the fluid to be pumped from entering the pump stages, since if the proportion of air or gas is too high, the pump will be the liquid does not promote properly. Due to the greater mass, the fluid in the impeller air-jet is accelerated more than the air or gas present in the fluid. The fluid is moved radially further outwardly so that it exits the impeller radially further outward from the impeller than the air or gas at the axial exit, while the air exits radially further inward.

The Submersible pump application of the air separator is not necessarily true directly the application of the same in the sanitary and heating technology.

The German utility model DE 20 2007 011 594 discloses an air separator of a small type, in which flow-deflecting baffles, profiles or baffles are introduced as separate components or in connection with the flow-carrying pipeline for the enforcement of a residence time of the medium in the air separation space. The separator is very compact, but also leaves little room and thus volume and residence time for the medium, weed out air. The separated air collects in the upper part of the separator and can be discharged via a pipe socket manually by means of a vent valve or semiautomatically via a float valve.

Of the Flow resistance is due to the strong turbulence in a confined space big; depending on prevailing pressure conditions - solar systems are driven with about 6 bar pressure - the medium can hardly Separate air in peace and in the upper space of the separator itself collect and, if necessary, with the outgoing flow carried away again.

The German patent DE 693 07 870 / European registration EP 633 807 introduces a separator-separator for separating solid from liquid.

The utility model DE 202 06 564 introduces an air separator and an idling aid for solar systems without antifreeze. Idle or drain-back systems come without further heat exchanger, the heat storage itself serves as a return tank; Here, pure water is usually pumped through the collectors. In the event of sun failure, the water runs back into a reservoir to prevent frost damage to the system. When the system is shut down, air is drawn into the system through emptying, which then has to be sucked out again during operation in order to achieve the pump's output.

Between Flow and return line before one in the flow line located siphon becomes a connecting line with check valve attached as a backflow preventer, which in Dependence of the pump works and by means of a closure body in the valve got air bubbles separates.

The international patent application WO 1996/035495 presents a vortex air separator for heat transfer heating systems. The air separator consists of a hollow cylindrical housing with lateral, top inlet and outlet, a helically wound wire screen as a separation element whose center axis coincides with the central axis of the hollow cylinder, wherein the outlet is separated from the interior by a chicane, that the liquid medium always leaking over the floor area. The surface of the separation element reduces the flow rate of the water and changes its direction of flow with minimal pressure drop. Besides the wire screen, bristled and brush-like separators are also proposed. At the top, the hollow cylinder is closed by a conical cap as Luftsammeldom, which is also a carrier of a float-breather.

Of the Separator stands in the hollow cylinder in the middle on one with edge perforations provided disc, but which lies on the cylinder bottom - and not spaced from the ground - where the openings the disc can have no effect.

The utility model DE 68 01 723 presents an air separator - essentially a housing consisting of the bottom, one right and left side end wall and a top wall with a total of each wall an optional supply port, a sidewall measuring port and a sixth for the vent - mounted directly in the vicinity of the boiler can be. The outline of the interior is done by a baffle, which is mounted immediately above the bottom-side inlet and causes the supplied medium is deflected to the wall and swirled behind her. The freed air should collect above the turbulence between two storage walls below the vent port and be discharged through it.

The Vortex formation and air separation certainly depends decisively from that - in addition to the bottom inflow - between three outlets to choose from. The housing can also have a safety valve and a pipe take up to the expansion vessel.

A very similar to this appearing air separator is in the publication of the utility model DE 19 46 121 presented. Even if the geometry deviates slightly, the structure and number of connections and their use are almost exactly the same.

With the utility model DE 19 95 660 An air separator for a water central heating system is presented, whose installation is intended in the main riser of the heating system. The air separator consists of a hollow cylindrical vessel into which tangential arcs of the main riser lead. Above the vessel, a float-controlled automatic ventilator is provided, which is connected via a connecting piece with the vessel, as well as a pressure equalization vessel positioned below. Rising water in the main riser is laterally pressed into the hollow cylinder, swirling on its inner wall, rising within the vessel and leaving it over the elbow of the continuing main riser. Swirled-out air components rise above the nozzle and socket in the venting machines and blow off.

It are no baffles or plates to reinforce the Water vortex provided; a cone-shaped pronounced Vessel space above the elbow exit (and below the deaeration vessel) can save the released air shares.

The utility model DE 18 01 002 presents an air separator for the apparatus construction, which is composed of a combination of thermostat and float, both of which act on an outlet with a conical valve, which in turn can be backed by a ball valve. When used for apparatus containing hot liquids or gases other than a liquid, the thermostat closes the air outlet when a certain temperature is reached, regardless of whether this temperature is generated by the liquid or the vapors. As long as the closing temperature is not reached, the valve is open for gases and liquids. In order to prevent this for liquids, the float is also effective.

This Air separator unfolds its effect preferably in industrial Process technology in the area of large plants.

The Austrian patent AT 255 706 / German Auslegeschrift DE 12 31 869 describes an air separator, in particular for a heating system operated with a circulation pump. The air separator is characterized in that the screen is formed as provided with holes flat screen plate and arranged at an angle to the running in the longitudinal axis of the switched-circulation in the housing housing flow direction, thereby dividing the flow space into two rooms and with its free end in the also in Angle to the housing arranged air outlet nozzle protrudes. Preferably, the screen plate and the air outlet nozzle are arranged at an angle of about 45 °.

The Sieblöcher the screen plate are so small that they even the smallest, carried by the water flow bubbles safely from Separate water; but that also means that of the circulating water entrained foreign bodies - such as welding and solder balls and hemp threads - the screen plate for a short time clog with the result of an increase in the flow resistance. A measuring device is not provided. secluded Air bubbles accumulate in the upper filter chamber and leave the separator in an air collection container or to an expansion vessel.
