Abstract

The foam rubber balls (1) for use in cleaning condenser or heat exchanger pipes using the processes of the firm Taprogge or Klump & Koller GmbH or according to are produced with a cavity (4) in the center if dense rubber is used or with a heavy core if the rubber is less dense.

Description

Die Erfindung betrifft zu den Kondensatoren der Dampfturbinen oder den Rohrwärmeübertragern.The Invention relates to the capacitors of steam turbines or the Rohrwärmeübertragern.

Die kann auf den Warm- und Atomkraftwerken verwendet sein.The can be used on thermal and nuclear power plants.

Es ist die Weise der Reinigung der inneren Oberfläche der kühlenden Röhren der Kondensatoren und der Wärmeübertrager von den Ablagerungen mithilfe der vollen Schwammgummikugeln nach dem Verfahren der Firmen Taprogge und Klump&Koller GmbH bekannt, s. z. B.: DE 3917520 C2 , DE 4410871 A1 , DE 102511736 A1 DE 19945282 A1 , DE 19945282 C2 , DE 29610898 U1 , DE 29610899 U1 , DE 29817221 U1 , DE 69701288 T2 , EP 0808205 , EP 0808205 B1 , EP 0906550 , EP 0906550 B1 .The way of cleaning the inner surface of the cooling tubes of the condensers and the heat exchangers is known from the deposits by means of the full sponge rubber balls according to the method of the companies Taprogge and Klump & Koller GmbH, see for example: DE 3917520 C2 . DE 4410871 A1 . DE 102511736 A1 DE 19945282 A1 . DE 19945282 C2 . DE 29610898 U1 . DE 29610899 U1 . DE 29817221 U1 . DE 69701288 T2 . EP 0808205 . EP 0808205 B1 . EP 0906550 . EP 0906550 B1 ,

In diesem Verfahren werden die Schwammgummikugeln 1 in den Strom des Umlaufwassers in einem Punkt eingeführt, dabei wird die gleichmäßige Zuordnung der Schwammgummikugeln in den Röhren des Kondensators oder des Wärmeübertragers gewährleistet, s. z. B.: DE 29610900 U1 , DE 69405520 T2 , DE 69701289 T2 , EP 0655121 , EP 0906551 , EP 0906551 B1 .In this process, the sponge rubber balls 1 introduced into the flow of circulating water in one point, while the uniform allocation of the sponge rubber balls in the tubes of the condenser or the heat exchanger is ensured, see for example: DE 29610900 U1 . DE 69405520 T2 . DE 69701289 T2 . EP 0655121 . EP 0906551 . EP 0906551 B1 ,

Es hat auch die Weise der Einführung der Schwammgummikugeln vorgeschlagen, in der sowohl gleichmäßig als auch die regulierte Zuordnung der Schwammgummikugeln in den Röhren der verschiedenen Zonen des Rohrbündels des Kondensators oder des Wärmeübertragers gewährleistet sein kann, s. Nr. 10 2006 018 996.5.It also has the way of introduction of sponge rubber balls proposed in both equally and also the regulated assignment of sponge rubber balls in the tubes the different zones of the tube bundle of the capacitor or the heat exchanger guaranteed can be, s. No. 10 2006 018 996.5.

Für beide Fällen zu den physikalische-chemischen Eigenschaften der Gummimischung, aus der die Schwammgummikugeln hergestellt werden, werden die hohen Forderungen vorgelegt.For both cases to the physico-chemical properties the rubber compound from which the sponge rubber balls are made become submitted the high demands.

Besonders ist es dann zu Recht, wenn die Schwammgummikugeln in einem Punkt eingeführt werden, da die Kugeln in diesem Fall bis zu der Rohrplatte die größere Strecke gehen sollen.Especially is it then right when the sponge rubber balls in one point be introduced because the balls in this case up to the tube plate should go the greater distance.

Für die Vergrößerung des Sortiments der Gummimischungen, die für die Herstellung der ähnlichen Schwammgummikugeln brauchbar werden, wird es vorgeschlagen, das Zentrum der Schwammgummikugel hohl oder im Gegenteil (umgekehrt) schwer zu machen.For the enlargement of the assortment of rubber compounds, those for making similar sponge rubber balls become useful, it is proposed, the center of the sponge rubber ball hollow or on the contrary (in reverse) difficult to do.

Das Auswählen der einen aus zweien Varianten der Modifikation der Technologie der Herstellung der Schwammgummikugeln hängt von den physikalische-chemischen Eigenschaften der Gummimischung ab, aus der vermutet wird, die Schwammgummikugeln zu herstellen.The Select one of two variants of the modification the technology of making sponge rubber balls hangs from the physical-chemical properties of the rubber compound which is suspected of making the sponge rubber balls.

Die Erfindung hat auf den nächsten Figuren vorgestellt:The Invention has presented on the next figures:

Die 1. Die Bildung der Höhle innen der Schwammgummikugel.The 1 , The formation of the cave in the sponge rubber ball.

Die 2. Die Bildung des kleinen schweren Kernes innen der Schwammgummikugel.The 2 , The formation of the small heavy core in the sponge rubber ball.

Auf der 1 wird der Zweck dadurch erreicht, dass nach der Herstellung der Schwammgummikugel 1 mithilfe der existierenden Technologie in das Zentrum der Kugel die dünne Sonde 2 eingeführt wird.On the 1 the purpose is achieved in that after the production of sponge rubber ball 1 using the existing technology in the center of the sphere the thin probe 2 is introduced.

Das Ende der Sonde stellt die Schlinge 3 dar.The end of the probe represents the noose 3 represents.

Zur Sonde wird der Strom kurzzeitig zugeführt.to Probe the current is supplied for a short time.

Die Schlinge erglüht und brennt in der Schwammgummikugel die kleine Höhle 4 aus.The noose burns and burns in the sponge rubber ball the small cave 4 out.

Die Parameter des Stromes, die Erwärmungzeit und die Größe der Höhle sollen experimental für jede Gummimischung ausgewählt sein, aus der vermutet wird, die Schwammgummikugeln herzustellen.The Parameters of the current, the heating time and the size The cave should be experimental for any rubber compound be selected from the suspected, the sponge rubber balls manufacture.

Auf der 2 wird der Zweck dadurch erreicht, dass die Spritze 6 in das Zentrum der Schwammgummikugel 1 nach der Herstellung der Kugel mithilfe der existierenden Technologie eingeführt wird.On the 2 the purpose is achieved by having the syringe 6 into the center of the sponge rubber ball 1 after making the ball is introduced using the existing technology.

Mithilfe der Spritze in die Schwammgummikugel wird die kleine Portion des flüssigen Polymers 7 mit dem spezifischen Gewicht mehr, als das spezifische Gewicht des Materials der Schwammgummikugel eingeführt.Using the syringe in the sponge rubber ball, the small portion of the liquid polymer 7 with the specific gravity more than the specific gravity of the material of the sponge rubber ball introduced.

Es wäre wünschenswert, dass das Polymer 7 bei der Zimmertemperatur verhärtet hat (die Polymerisation beendet).It would be desirable for the polymer 7 has hardened at room temperature (the polymerization has ended).

In diesem Fall wird die zusätzliche Wärmebehandlung schon der fertigen Kugel nicht gefordert. Solches Polymere gibt es.In In this case, the additional heat treatment already not required the finished ball. Such polymers exist it.

Die notwendige Portion des Polymers soll experimental für jede Mischung ausgewählt sein, aus der es vermutet wird, die Schwammgummikugeln herzustellen.The necessary portion of the polymer should be experimental for each Be selected mixture from which it is suspected that Make sponge rubber balls.

Andere Variante der Bildung des schwereren Kernes besteht darin, dass die Metallisch- oder Polymerkugel des kleinen Durchmessers in das Zentrum der vollen Schwammgummikugel nach ihr Herstellung eingeführt wird.Other Variant of the formation of the heavier core is that the Metallic or polymer sphere of small diameter in the center of full sponge rubber ball introduced after her manufacture becomes.

Der Durchmesser der Kugel soll experimental ausgewählt sein.The diameter of the ball should experiment tal selected.

Zur Zeit existieren die Technologien der Herstellung der hohlen Schwammgummikugeln aus der Gummimischung, zum Beispiel mithilfe des Extruders mit dem Blaskopf.to Time exist the technologies of production of hollow sponge rubber balls from the rubber compound, for example with the help of the extruder Blow head.

Für sie Herstellung kann die Technologie verwendet sein, die zum Beispiel in RU 2005 111 430 beschrieben hat.For their manufacture, the technology used, for example, in RU 2005 111 430 has described.

Für die verhältnismäßig leichten Mischungen in die Höhle (4) der hohlen Schwammgummikugel kann der schwere Kern des beschriebenen höher Typs eingeführt sein.For the relatively light mixtures in the cave ( 4 ) hollow sponge rubber ball the heavy kernel of the described higher type can be entered.
