Upflow reactor

Technical Field

The utility model relates to the technical field of reactors, in particular to an upflow reactor.

Background

Conventional reactor R4102 defect: the oil product cannot be uniformly distributed at each radial position of the bed after entering from the bottom.

Causes of reactor defects: the original reactor is arranged to be up-in and down-out, and the bottom inlet is only provided with a bearing disc without a corresponding distributor.

Disclosure of Invention

The utility model aims to solve the technical problems and provide an upflow reactor which can uniformly distribute feeding materials and reduce the bias flow phenomenon of a bed layer.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows:

the utility model provides an upflow reactor, the reactor bottom is provided with the feed inlet, and the interior bottom is provided with the entry disperser that is connected with the feed inlet, and the inside position department that is close to interior bottom of reactor cup joints fixedly has the catalyst supporting disk, and the reactor middle part is provided with cold hydrogen import, and the top is provided with the export collector, be provided with the discharge gate on the export collector.
