First, you would be better to ask in the tor-talk list, because your question is about how to configure and use Tor rather than how to improve its internals.
You can run multiple Tor instances on the same machine. It merely requires management of the config files to keep the ports separate. Privoxy and polipo or other http proxies are usually no longer needed. See https://www.torproject.org/docs/faq.html.en#TBBPolipo
Finally, why would you *not* want your website scraping requests to come from the same exit node? (Note that a new exit node is chosen approximately every 10 minutes for web connections.) If you are trying to avoid getting banned from a site that disallows periodic scraping, for example Craigslist, using multiple exit nodes (aka circuits) will soon result in the entire Tor network being banned by the target site, denying anonymous users that valuable resource.

Thanks a lot for your reply :) I know that we can add up more SocksPort into torrc file, however, my current idea is to build different tor threads. In my opinion, a complete tor threads starts from privoxy(polipo. etc.), then point 8118 to 9050 as default, then tor points 9050 to the outside networks.. What I want to do is build many threads like this, for example, I have $ ls /etc/tor
torrc torrc2 torrc3 torrc4...
torrc points to 9050, torrc2 points to 9150..etc at the same time, running different privoxies, privoxy points 8118 to 9050, then privoxy2 points 8119 to 9150, etc.... https://trac.torproject.org/projects/tor/wiki/doc/RunTwoPrivoxys I am still struggling with it.. and not quite sure whether this is applicable and is there any better solution to run multiple threads of tor.
