You can only destroy a Ring Portal with external tools or special cheat mods. About the tools, either use a NBT editor, find the chunk, and delete the entity data, or use NBTEdit, find the location (should be easier thanks to the 3D representation of the world), select the blocks around the entity, and use the tool for deleting entities.
