Detachable deuterated compound fixed bed reactor

The invention relates to the technical field of fixed bed reactors, and provides a detachable deuterated compound fixed bed reactor which can prevent reactants from being adhered to the surface of an inner container and improve the contact efficiency of a catalyst inner container and the reactants. The first driving motor rotates to drive the rotating shaft to rotate, the rotating shaft rotates to drive the bottom scraping plate and the side scraping plate to scrape the bottom and the side face of the inner container, reactants are prevented from being bonded to the surface of the inner container, and the contact efficiency of the catalyst inner container and the reactants is improved. According to the reactor, a first driving motor rotates to drive a rotating shaft to rotate, the rotating shaft rotates to drive a rotating disc to rotate, the rotating disc rotates to drive a push rod to reciprocate through a sliding block and a connecting rod, then a sliding plug is driven to reciprocate, the sliding plug rec
