Ever means "always", or "for the entirety of time".
Consequently
A passion for books and the words inside them saved me from ever knowing a moment’s loneliness.
means that "A passion for books and the words inside them" are responsible for the author never "knowing a moment's loneliness".
The sentence then ends with an additional time constraint:
A passion for books and the words inside them saved me from ever knowing a moment’s loneliness during library hours.
What this caveat does is it constrains "never" to mean "whilst the library was open".
So in conclusion, the sentence as a whole means that whilst the library was open for business, "a passion for books and the words inside them" saved the author from "knowing a moment's loneliness".
