Abstract
The utility model discloses a kind of fluid bed feed distributor, including feed pipe, the feed pipe rear end is provided with conical head；Described less one end of conical head is connected with feed pipe；The subregion dividing plate of some tapered sleeve shapes is provided with the conical head；The subregion dividing plate is nested arrangement successively from big to small, and with conical head towards consistent and coaxial；Some supporting plates are provided between conical head and the subregion dividing plate, between subregion dividing plate and subregion dividing plate.Fluid bed feed distributor with said structure, after carrying out subregion to import, each section charging of the substantially uniform distribution of gaseous mixture, flow and pressure differential reduce away from further everywhere on subregion dividing plate, Internal and external cycle catalyst is preferably blown afloat on subregion dividing plate, catalyst buildup degree on subregion dividing plate is reduced, extends the fluid bed repair and maintenance cycle, also further ensures the lasting Effec-tive Function of production.
Description
Technical field
It the utility model is related to a kind of feed distributor for fluid bed.
Background technology
Existing fluidized-bed bottom feeder is only carried out excessive by a smooth conical head.When nitrobenzene and hydrogen mix
Gas is closed when 0.2Mpa or so pressure is fed, most gaseous mixtures directly pass through in the middle part of distribution grid, cause marginal portion gas
Amount and air pressure deficiency, distribution plate edge portion catalyst can not be mixed gas and fully blow afloat.Catalysis has been resulted in long process
The accumulation of agent even blocks, and so as to cause distribution grid pressure difference big, the serious curtailment time between overhauls(TBO), influences production and continues efficiently to enter
OK.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of fluid bed feed distributor, and charging aperture is entered
Row subregion, reduce its flow and pressure differential.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of fluid bed feed distributor,
Including feed pipe, the feed pipe rear end is provided with conical head；Described less one end of conical head is connected with feed pipe；Institute
State the subregion dividing plate that some tapered sleeve shapes are provided with conical head；The subregion dividing plate is nested arrangement successively from big to small, and
It is consistent and coaxial with conical head direction；Set between conical head and the subregion dividing plate, between subregion dividing plate and subregion dividing plate
It is equipped with some supporting plates.
As an improvement the subregion dividing plate is not of uniform size three, charging aperture is divided into 4 together with conical head
Subregion.
As an improvement outermost layer and the subregion dividing plate in intermediate layer are the same as high；And larger one end of subregion dividing plate of innermost layer
Flushed with intermediate layer subregion dividing plate, smaller one end is less than intermediate layer subregion dividing plate.If innermost layer subregion dividing plate set and its
If the same height of his subregion dividing plate, innermost layer subregion import can be caused too small so as to cause difficult feed so that flow pressure is distributed
It is uneven.
As an improvement the supporting plate is twist arranged.The supporting plate of helical form arrangement is first to each layer subregion
Dividing plate is supported, and increases the strong point, improves intensity；Cause charging to form turbulent flow simultaneously, improve its fluid effect.
As a preferred embodiment, the diameter of the feed pipe is consistent with outermost layer subregion dividing plate small end diameter.
It is of the present utility model to be beneficial in that：Fluid bed feed distributor with said structure, by entering to import
After row subregion, the substantially uniform each section of distribution of gaseous mixture is fed, and flow and pressure differential reduce away from further everywhere on subregion dividing plate,
Internal and external cycle catalyst is preferably blown afloat on subregion dividing plate, is reduced catalyst buildup degree on subregion dividing plate, is extended fluidisation
In the bed repair and maintenance cycle, also further ensure the lasting Effec-tive Function of production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure：1 feed pipe, 2 conical heads, 3 subregion dividing plates, 4 supporting plates.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in figure 1, the utility model includes feed pipe 1, the rear end of feed pipe 1 is provided with taper and seals 2；The cone
2 less one end of shape end socket is connected with feed pipe 1；The subregion dividing plate 3 of some tapered sleeve shapes is provided with the conical head 2；Institute
Subregion dividing plate 3 is stated to be nested successively from big to small arrangement, and with conical head 2 towards consistent and coaxial；The conical head 2 with
Between subregion dividing plate 3, some supporting plates 4 are provided between subregion dividing plate 3 and subregion dividing plate 3.
Subregion dividing plate 3 is preferably not of uniform size three, and charging aperture is divided into 4 subregions together with conical head 2.
Outermost layer and the subregion dividing plate 3 in intermediate layer are the same as high；And 3 larger one end of subregion dividing plate of innermost layer and intermediate layer subregion
Dividing plate 3 flushes, and smaller one end is less than intermediate layer subregion dividing plate 3.
Supporting plate 4 is twist arranged.The supporting plate 4 of helical form arrangement is supported to each layer subregion dividing plate 3 first, is increased
Add the strong point, improve intensity；Cause charging to form turbulent flow simultaneously, improve its fluid effect.
The diameter of feed pipe 1 is consistent with the small end diameter of outermost layer subregion dividing plate 3.
Charging aperture is divided into 4 sections by three subregion being nested dividing plates 3, mixed gas is uniform in each section
Distribution, reduce in charging aperture the gap of flow and pressure everywhere so that catalyst is preferably blown afloat, and reduces catalyst
Accumulation degree.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
