Description
Technical field
The utility model belongs to petrochemical industry and coal chemical technology, relates to a kind of gas feed distributor that is used in fluidization reaction regeneration device reactor or the regenerator.
Background technology
In the reactor or regenerator in the fluidization reaction regeneration device of petrochemical industry and coal chemical technology, if gas feed skewness in fluid bed, can cause the fluid bed bias current, gas feed can not be contacted equably with catalyst, cause phenomenons such as reacting not exclusively or burn weak effect.For avoiding the gas feed skewness, generally take to dwindle jet velocity that gas feed distributor nozzle diameter (referring to its interior diameter) improves gas feed, increase and make the equally distributed annex of gas feed and increase method such as fluidized bed layer height.The gas feed distributor of present industrial use mainly contains two types: board-like feed distributor and dendroid tubular type feed distributor.Chinese patent CN1923964A has introduced a kind of inner member that is used to improve catalytic-cracking reaction system gas-solid contact, comprises a pore size distribution plate and tube bank.Wherein the pore size distribution plate is positioned at the bottom of low linear speed reaction zone, has some holes on the distribution grid, and perforated area is greater than 30% of high linear speed reaction zone area, simultaneously less than low linear speed reaction zone area.Tube bank is made of straight tube, and the bottom of straight tube links to each other with hole on the pore size distribution plate, the shape of straight tube bottom and size respectively with the pore size distribution plate on corresponding hole identical, the straight tube maximum length in the tube bank is not more than the height that hangs down the linear speed reaction zone.CN2603690Y discloses a kind of fluidized-bed reactor gas distribution grid.It has gas distribution grid, and gas distribution grid is provided with air admission hole, blast cap of sealing welding on each air admission hole of gas distribution grid, and on blast cap, have two or more circles, square spray-hole or rectangular spray slits.In blast cap inside, air admission hole upper end is provided with the leakproof weir of a circle, square or taper.These two patents all belong to board-like feed distributor, increase to make the equally distributed annex of gas feed on distribution grid.Dendroid tubular type feed distributor is referring to the introduction of " oil Refining Technologies and engineering " 2006 the 36th the 3rd phases of volume " the gas phase flow field analyses of catalytic cracking regenerator dendroid distributor pipe of cardinal wind wearing and tearing " literary composition.
Distribution requires reactor or the regenerator in the not too strict fluidization reaction regeneration device for gas feed, adopts board-like feed distributor or dendroid tubular type feed distributor can satisfy the requirement of technology well.But for some technology, for example MTO (methanol conversion system alkene) technology require gas feed and catalyst short-time contact, reaction, thereby the fluidized bed layer height is less; Strict time of contact to the catalyst in fluid bed bed height, gas feed and the bed, can not adopt the method for increasing bed height that gas feed is evenly distributed.Simultaneously,, do not allow gas feed evenly to be distributed, otherwise can cause the erosion of high velocity air, make catalyst breakage, increase the losing quantity of catalyst catalyst with the method that improves the gas feed jet velocity because of the catalyst that uses is expensive.Gas feed distributor increases simply makes the equally distributed annex of gas feed, acts on limitedly, can not fundamentally solve gas feed problem pockety.Gas feed distributor in the fluidization reaction regeneration device in reactor or the regenerator adopts existing board-like feed distributor or dendroid tubular type feed distributor, can not satisfy the requirement of these technologies fully.
Summary of the invention
The purpose of this utility model provides a kind of gas feed distributor, can not make the equally distributed well problem of gas feed to solve methanol conversion system alkene etc. the existing gas feed distributor of process using is existing.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of gas feed distributor, it is characterized in that: it is made up of dendroid tubular type feed distributor and board-like feed distributor, board-like feed distributor is by middle dull and stereotyped, arc be connected the arc plate and form, which is provided with board-like feed distributor nozzle, the bottom that connects the arc plate is provided with support plate, board-like feed distributor is supported on the wall of equipment, dendroid tubular type feed distributor is located at the below of board-like feed distributor, it is by the person in charge, arm and branched pipe are formed, one end of arm links to each other with the person in charge, the other end is a blind end, one end of branched pipe links to each other with arm, and the other end is a blind end, and the bottom tube wall of branched pipe is provided with dendroid tubular type feed distributor nozzle.
Adopt the utility model, have following beneficial effect: the utility model is combined by existing dendroid tubular type feed distributor and board-like feed distributor.During operation, gas feed at first enters dendroid tubular type feed distributor, and the person in charge that flows through, arm, branched pipe by the ejection of dendroid tubular type feed distributor nozzle, carry out the primary distribution of gas feed.After this enter the cavity that constitutes by board-like feed distributor, support plate and equipment wall, further evenly distribute at this.Afterwards, gas feed evenly sprays through board-like feed distributor nozzle, carries out secondary distribution.After the distribution of gas feed through two feed distributors, in fluid bed, can evenly distribute well, and in the shortest time, contact fully, equably, react with catalyst.Because gas feed is through the once distribution of dendroid tubular type feed distributor, board-like feed distributor nozzle adopts lower jet velocity that the gas feed secondary is evenly distributed, and so just can not cause the serious erosion of air-flow to catalyst.In addition, must not increase the fluidized bed layer height and can reach the equally distributed purpose of gas feed.The utility model can be used for being particularly useful for the reactor of MTO technology in the reactor or regenerator in the fluidization reaction regeneration device as a kind of novel gas feed distributor.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.The drawings and specific embodiments do not limit the claimed scope of the utility model.
