Is 2.5 hours quick enough to land in Hong Kong and board a plane back to Shanghai?

I need to do a quick visa run on my multi entry visa. I've found some good flights but I land in Hong Kong at 11:00am and my flight back to Shanghai is at 13:35pm.

I've never been to Hong Kong airport so I don't know if this is possible to get from departures to arrivals.

Can anyone offer any advice
