Despite its grandeur, Shanghai Airport does not have any arrangement for prayer rooms, whether Muslim or other faiths. Muslims, however, need to find secluded areas of the departure or check-in areas. Good to check with Airport staff where one can do this. 

Visit our Qiblah direction locator page and enter Shanghai Pudong  Airport and you will be able to get an idea of the Qiblah direction. One can also try contacting airport desks for directions.
