Abstract

The invention relates to the technical field of spray drying, and discloses a spray drying device, which comprises a drying barrel (130), a spraying structure (400) and a transmission structure (300), wherein the spraying structure (400) extends into the drying barrel (130) through the top opening of the drying barrel (130), and the spraying structure (400) is connected with the transmission structure (300), so that the spraying structure (400) moves in a horizontal direction and / or a circumferential direction under thedriving of the transmission mechanism (300). According to the spray drying device, through the technical scheme, the transmission structure can drive the spraying structure to move in the horizontal direction and / or the circumferential direction, and dry spray sprayed by the spraying structure can make full and uniform contact with a catalyst in the drying barrel, so that the drying effect on the catalyst is greatly improved, the problem that the catalyst is easy to cake after being cooled is solved, and the catalyst is convenient to store and transport.

Description

technical field [0001] The invention relates to the technical field of spray drying, in particular to a spray drying device. Background technique [0002] MTO catalyst is the abbreviation of methanol-to-olefins catalyst, that is, the catalyst used in the process of producing olefins (ethylene and propylene) with high selectivity from methanol. sexual characteristics. The MTO catalyst collected from the MTO catalyst preparation device generally has a relatively high water content and needs to be dried. [0003] However, the existing MTO catalyst drying device cannot uniformly dry the catalyst, and the drying effect is poor, resulting in easy agglomeration after cooling, which is inconvenient for storage and transportation. Contents of the invention [0004] The object of the present invention is to provide a spray drying device for the above problems, which can uniformly dry the catalyst and has a good drying effect. [0005] In order to achieve the above object, the pre...
