Have muchly no matter goal of the invention of the present utility model provides a kind of liquid phase flow, can guarantee that all beds is soaked in liquid phase, so the novel catalytic rectifying tower that can be fully used of catalyst.
The designed catalytic rectifying tower of the utility model comprises the rectifying section III, catalyst reaction section II that links to each other with the rectifying section bottom and the profit reduction and reserving section I that links to each other with the catalytic reaction pars infrasegmentalis, particularly catalyst reaction section is provided with concentric inner core and urceolus, be provided with a plurality of catalyst beds 4 in the urceolus, each bottom is provided with porous support plate 7, gripper shoe is provided with hurdle net 8, catalyst is housed on the block, each below, catalyst bed bottom is provided with dividing plate 9, be provided with multistage column plate 5 in the inner core, each column plate both sides is connected with and is respectively applied for liquid phase and advances, go out the downspout 6 in column plate district, 6 ', described downspout is connected with the annular space that is divided into by each dividing plate and inner/outer tube respectively.
The designed catalytic rectifying tower of the utility model can also comprise that being used for the downspout that liquid phase enters the column plate district is connected with the bottom of catalyst bed, and the described downspout that is used for liquid phase outflow column plate district is connected formation downstriker structure with the top of catalyst bed.
The designed catalytic rectifying tower of the utility model can also comprise that being used for the downspout that liquid phase enters the column plate district is connected with the top of catalyst bed, and the described downspout that is used for liquid phase outflow column plate district is connected formation upstriker structure with the bottom of catalyst bed.
A plurality of cover bodies 11 of the column plate 5 of catalyst reaction section described in this catalytic rectifying tower have sulculus 12 for the cylindrical shape on band top, sidewall bottom, and top has a plurality of tangential slits 13, and the top has a plurality of apertures, and the cover body outside is provided with tubaeform outer cover 15.
A plurality of cover bodies 16 of the column plate 5 of catalyst reaction section described in this catalytic rectifying tower have sulculus 12 for the cylindrical shape on band top, sidewall bottom, and the top has a plurality of apertures 17.
Rectifying section described in this catalytic rectifying tower and profit reduction and reserving section have plate column or packed tower structure.Those skilled in the art can adopt conventional means to design voluntarily by instructions for use.
The design's catalytic rectifying tower in use, because catalyst is seated in the exterior annular pipe, can be according to required loaded catalyst, adopt larger-diameter urceolus, or employing is than the urceolus of minor diameter, and the height of catalytic rectifying tower is constant, so the design's catalytic rectifying tower is not only applicable to any type of chemical reaction, and highly lower; Particularly the structure of this catalytic rectifying tower is much no matter the liquid phase flow has, and can guarantee that all beds is soaked in liquid phase, so catalyst can be fully utilized; And two kinds of novel calotte structures can make vapour, liquid two-phase experience than long time of contact, thereby have high plate efficiency.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing 1 is a downstriker catalytic rectifying tower structural representation;
Accompanying drawing 2 is a upstriker catalytic rectifying tower structural representation;
Accompanying drawing 3 is the section schematic top plan view of the catalyst reaction section of catalytic rectifying tower shown in Figure 1;
Accompanying drawing 4 is A type calotte structural representation and section schematic top plan view;
Accompanying drawing 5 is a Type B calotte structural representation;
In the accompanying drawing, the label I is the profit reduction and reserving section, and II is a catalyst reaction section, III is a rectifying section, and 4 is beds, and 5 is column plate, 6 is downspout, and 7 is porous support plate, and 8 is the hurdle net, 9 is dividing plate, and 10 is the ring pipe in the outside, and 11 is cover body, 12 is the sulculus that open the sidewall bottom, and 13 is tangential slit, and 14 is the top aperture, 15 is tubaeform outer cover (A type), and 16 is thick short shape cover body (Type B).
The catalytic rectifying tower of a kind of liquid downstriker as shown in Figure 1, wherein profit reduction and reserving section I and rectifying section III are conventional sieve-plate tower, the agent structure of catalyst reaction section is two-layer concentric cylindrical structure, be provided with a plurality of catalyst beds 4 in the urceolus, each bottom is provided with porous support plate 7, gripper shoe is provided with hurdle net 8, the hurdle is equipped with catalyst on the net, below, catalyst bed 4 bottoms is provided with dividing plate 9, be provided with multistage column plate 5 in the inner core, each column plate both sides is connected with and is respectively applied for liquid phase and advances, go out the downspout 6 in column plate district, 6 ', downspout is connected with the annular space that is divided into by each dividing plate and inner/outer tube respectively, and is used for the downspout that liquid phase enters the column plate district and is connected with the bottom of catalyst bed, is used for the downspout that liquid phase flows out the column plate district and is connected with the top of catalyst bed; Cover body 11 on column plate 5 has sulculus 12 for the cylindrical shape on band top, sidewall bottom, and side wall upper part has a plurality of tangential slits 13, and the cylinder top has a plurality of apertures 14, and the cover body outside is provided with tubaeform outer cover 15.
