The specific embodiment
Referring now to accompanying drawing, cooling distributor of the present utility model is described.As shown in Figure 1, cooling distributor of the present utility model comprises distributing pipe 1 and at least one distribution plate 6.Wherein, distributing pipe 1 has outer tube 2 and inner tube 3, and inner tube 3 is arranged in outer tube 2 setting alternate with outer tube 2 at least in part, thereby forms the space of crossing for material flow between the outer wall of inner tube 3 and the inwall of outer tube 2.Particularly, each distribution plate 6 one end is provided with the first link 7 and the second link 8, and distribution plate 6 other ends are connected with nozzle 9.The first link 7 is communicated with inner tube 3, and the second link 8 is communicated with outer tube 2.In addition, the first link 7 and the second link 8 are also communicated with nozzle 9 respectively, thereby can be so that the outer tube 2 of distributing pipe 1 and inner tube 3 are communicated with nozzle 9 by the second link 8 and the first link 7 respectively.In optional embodiment, the size of inner tube 3 can be
and the size of outer tube 2 can be
In other words, in the time of in cooling distributor of the present utility model is applied to such as the device of MTP reactor, for reactor being carried out to liquid phase material and the gaseous phase materials of cooling down, can pass into respectively inner tube 3 and outer tube 2.That is, liquid phase material flows directly into inner tube 3, and gaseous phase materials flows into the pipeline forming between inner tube 3 and outer tube 2, and then liquid phase material enters distribution plate 6 through the first link 7, and gaseous phase materials enters distribution plate 6 through the second link 8.Two kinds of mixing of materials being sprayed by nozzle 9 atomizations in distribution plate 6, to carry out cooling down to reactor.It should be noted that liquid phase material and gaseous phase materials herein can be any material for MTP reactor is cooled.For example, liquid phase material can be cold Liquid Phase Methanol, water and dimethyl ether, and gaseous phase materials can be hot methyl alcohol and dimethyl ether steam.
Particularly, cooling distributor charging is divided into liquid phase material and gaseous phase materials or can be understood as the reaction temperature that cold/hot two-way charging is used for regulating MTP reactor.But because there is the incomplete phenomenon of vaporization after reaction feed, this can aggravate the coking of catalyst; While liquid touches catalyst surface and can sharply vaporize on surface, makes catalyst phase transformation aggravation reduce the intensity of catalyst, thereby reduces the conversion ratio of catalyst, causes catalyst to lose activity.Based on above reason, before charging, tackle liquid and carry out abundant atomization, make the liquid phase material that enters MTP reactor not have drop, thereby the performance that guarantees catalyst is not destroyed, and makes it reach maximum conversion ratio, therefore need the structure of the cooling distributor of this utility model to produce atomizing effect.
Therefore, with in prior art, separately gaseous phase materials and liquid phase material are passed into the cooling distributor that reactor mixes again and compare, cooling distributor of the present utility model can directly spray the material to mix, thereby can more effectively reduce the device temperature in course of reaction such as MTP reactor, and the adverse effect that in anti-locking apparatus, excess Temperature causes reaction.
In addition, owing to being distributed with 6 beds in MTP reactor, each section of beds bottom all can be provided with cooling distributor of the present utility model, thereby bed temperature is controlled in the large calorimetric that utilizes cooling distributor of the present utility model to take away reaction generation.Further, distribution plate 6 can be arranged to a plurality of, can guarantee like this material evenly ejection in MTP reactor, thereby guarantee evenly cooling.
