Abstract
It the utility model is related to a kind of new gas distributor, air inlet pipe, redistribution pipe, annular spread pipe, gas injection tube and the apparatus casing communicated by being sequentially connected forms, the outer gas of equipment is entered in gas distributor by gas distributor air inlet pipe, then it is flowed into gas redistribution pipe and the passage of annular spread pipe distribution, the gas injection tube being distributed by passage lower end flows out.The utility model overcomes gas phenomenon pockety, avoids the situation for dead band occur, greatly improves the operating efficiency of distribution distributor, and the gas distributor is rational in infrastructure, makes simple.
Description
Technical field：
Chemical Engineering and field of chemical equipment are the utility model is related to, the more particularly to fluid bed in chemical reaction device is anti-
Answer device.
Background technology：
In Chemical Manufacture, many chemical reactions are carried out in a fluidized bed reactor, gas in the middle and lower part of reactor or
Bottom enters, and makes the material in reactor be in fluidized state, and the reactant in reactor is uniformly distributed, and improves the conversion of reactant
Rate.At present, for Straight, branch pipe is distributed the gas distributor that most producers use in reactor bottom, this gas point
The deficiency of cloth device is that air inlet distal end flow velocity is low, dead band phenomenon be present, fluid bed fluid effect is poor, the easy shape in fluidized-bed reactor bottom
Into caking, make the conversion efficiency of reactant reduce.For overcome the deficiencies in the prior art, the purpose of this utility model there is provided
A kind of new gas distribution apparatus, the fluid effect of reactor is can guarantee that, improve yield and quality, cut down the consumption of raw materials, and
It is simple in construction, it is easily manufactured.
The content of the invention：
The utility model provides a kind of new gas distributor, avoids occurring dead band in fluidized-bed reactor and scabs existing
As.
The technical solution of the utility model is：A kind of new gas distributor, it is characterised in that：Communicated by being sequentially connected
Air inlet pipe, redistribution pipe, annular spread pipe, gas injection tube and apparatus casing composition, the outer gas of equipment pass through gas distributor
Air inlet pipe is entered in gas distributor, is then flowed into gas redistribution pipe and the passage of annular spread pipe distribution, is passed through
The gas injection tube outflow of passage lower end distribution.
Gas inlet pipe quantity described in the utility model is 1-10.
Horizontal positioned or slant setting is managed in gas redistribution described in the utility model.
Annular spread pipe described in the utility model is annular or polygon, and the spacing between each annular spread pipe is equidistant
Be evenly arranged or each annular spread pipe between spacing it is different.
Annular spread pipe described in the utility model is connected with redistribution pipe.
There are circular orifice, a diameter of 5-30mm of orifice plate inside gas injection tube described in the utility model.
The utility model gas distributor has following several advantages compared with existing gas distributor：
1. improving the degree that is evenly distributed of gas, make the fluidisation in reactor uniform.
2. avoid occurring dead band and the phenomenon that scabs in fluidized-bed reactor.
3. rational in infrastructure, simple, convenient processing and manufacture.
Brief description of the drawings：
Utility model is described further with reference to the accompanying drawings and examples
Fig. 1 the utility model overall structure diagrams
In figure, 1, air inlet pipe 2, redistribution pipe 3, annular spread pipe 4, gas injection tube 5, equipment shell
Body
Embodiment：
With reference to accompanying drawing, the present invention will be further described;The quantity of air inlet pipe 1 can have one or more, a such as air inlet
Manage, then Inlet Position enters at device bottom center vertically into or bottom upper level；If any multiple air inlets, air inlet pipe
Leave device bottom center line in position；Redistributor 2, both can be with water also with the UNICOM of annular spread pipe 3 both with the UNICOM of air inlet pipe 1
Safety fills, and can also tilt installation；Circle distributor 3 both can be cirque structure, or polygonized structure, with dividing again
The UNICOM of stringing 2；Gas injection tube 4 is pipe, is provided with circular orifice in pipe, orifice plate diameter 5-30mm, gas injection tube 4 with
Annular spread pipe UNICOM, the outgassing direction of gas injection tube is downwards or obliquely, blows to apparatus casing wall direction, so made
Catalyst and reactant in reactor are in fluidized state, avoid gas concentration of local or dead band situation occur, are greatly improved point
Cloth efficiency.
Above example is merely to illustrate the present invention, is not intended to limit the invention, and comes for those skilled in the art
Say, the present invention there can be various modifications and variations.All any modifications within the spirit and scope of the present invention principle, made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
