Apparatus and method for degassing
View Patent ↗An apparatus for degassing of gaseous components from at least one curable material, particularly a curable material for building a composite part, for example, a rotor blade for a wind turbine, is provided in an embodiment herein. The apparatus includes at least one degassing chamber having at least one inlet for introducing a curable material for building a composite part, the curable material containing gaseous components into the degassing chamber and at least one outlet for removing a degassed curable material from the degassing chamber and at least one mechanical splitting means adapted to mechanically split up gaseous components contained within the curable material so as to release the gaseous components from the curable material.
1. An apparatus for degassing of gaseous components from at least one curable material, the apparatus comprising:
at least one degassing chamber having at least one inlet for introducing a curable material for building a composite part, the curable material containing gaseous components, into the degassing chamber and at least one outlet for removing a degassed curable material from the degassing chamber, and
at least one mechanical splitter adapted to mechanically split up gaseous components contained within the curable material so as to release the gaseous components from the curable material,
wherein the at least one mechanical splitter comprises an atomising nozzle.
2. The apparatus according to claim 1 , wherein the nozzle is disposed at or integrated within the inlet of the degassing chamber.
3. The apparatus according to claim 1 , wherein the nozzle is directed oriented towards at least one gas outtake for removing gaseous components released from the curable material of the degassing chamber.
4. The apparatus according to claim 1 , wherein the at least one mechanical splitter further comprises a rotational stirrer adapted to mechanically split up gaseous components contained within the curable material or comprises at least one rotational stirrer adapted to mechanically split up gaseous components contained within the curable material.
5. The apparatus according to claim 4 , wherein the rotational stirrer is disposed in the region of at least one gas outtake for removing gaseous components released from the curable material from the degassing chamber.
6. The apparatus according to claim 1 , further comprising at least one surface increasing element adapted to increase the inner surface of the degassing chamber.
7. The apparatus according to claim 1 , wherein the apparatus further comprises at least one vacuum generator adapted to generate a pressure below atmospheric pressure, within the degassing chamber.
8. A method for degassing of gaseous components from a curable material for building a composite part, comprising:
degassing of the gaseous components from the curable material with the apparatus of claim 1 .
9. The apparatus of claim 1 , for degassing of gaseous components from a curable material, for building a composite part.
10. The apparatus of claim 9 , wherein the composite part comprises a rotor blade for a wind turbine.
11. The apparatus of claim 7 , wherein the at least one vacuum generator is adapted to generate a vacuum.
12. The method of claim 8 , for degassing of gaseous components from a curable material for building a rotor blade of a wind turbine.
13. An apparatus comprising:
a degassing chamber comprising an inlet for introducing a curable material containing gaseous components into the degassing chamber and comprising an outlet for removing a degassed curable material from the degassing chamber;
a pump in fluid communication with the degassing chamber and operable to generate a pressure below atmospheric pressure within the degassing chamber;
a mechanical splitter adapted to mechanically split up the gaseous components contained within the curable material; and
a moulding apparatus in fluid communication with the degassing chamber outlet for receiving the degassed curable material.
14. The apparatus of claim 13 , wherein the mechanical splitter comprises an atomizing nozzle.
15. The apparatus of claim 13 , wherein the mechanical splitter comprises a stirrer adapted to destroy a foam structure containing the gaseous components and curable material originating from the pressure below atmospheric pressure in the degassing chamber.
