Each air guide Bottomhole pressure, and flow in each guider being connected with venthole in each airway tube.
In the present embodiment, the quantity of venthole, the shape of venthole and the venthole set on board-like distributor
Distribution situation can be determined according to business need.Such as, for large-scale reactor, distributor body can use corrugated
Cross section Design, the bed quality for carrying fluid bed.Should further be noted that the shape of venthole will be opened with guider
The shape at mouth end matches, so that guider can be connected with venthole.
Board-like distributor is a circular plate-like shape structure in the top view for board-like distributor shown in Fig. 3, this figure, and is wrapped
The venthole included is circular venthole.When reactor air inlet transmits reacting gas to board-like distributor, reacting gas leads to
Each venthole is crossed to flow in each guider being connected with venthole.In addition, board-like distributor surrounding be evenly arranged to
A few bolt hole 302, board-like distributor is fixed by these bolts hole and reactor shell.
In the present embodiment, what is no matter selected is the number of board-like distributor or pipe distributor, venthole and guider
Magnitude relation at least may have following two situations：
Situation one：Each venthole on distributor body corresponds to one guider of connection.Such as, board-like distributor
In be provided with 100 ventholes, then each venthole in 100 ventholes corresponds to one guider of connection.
Situation two：There was only venthole correspondence one guider of connection in part in all ventholes on distributor body.
Such as, 100 ventholes are provided with board-like distributor, then only have 50 outlet pore size distribution correspondences to connect in 100 ventholes
Connect a guider.It is noted herein that the distribution situation of the venthole of connection guider can be true according to business need
It is fixed, such as can be with distributor body horizontal center line as boundary, the venthole on the upside of horizontal center line corresponds to connection one
Individual guider, and the venthole on the downside of horizontal center line is not connected to guider.
According to above-described embodiment, distributor body can include pipe distributor or board-like distributor, can be according to difference
Business need choose the type of distributor body, therefore improve the application flexibility of distributor body.
In an embodiment of the invention, the guider in structural representation as shown in Figure 1 is the pipe that one end is closed
Shape structure, and it is provided with tube wall at least one through hole.
In the present embodiment, the concrete shape of tubular structure can be determined according to business need, such as can be square tube
Shape structure can also be round tube shape structure.Shape, size and the depth of cavity can be according to business in other tubular structure
It is required that determining, such as the cylindrical cavity from a diameter of 5 millimeters.
In the present embodiment, the number and shape of the through hole set on the tube wall of tubular structure can also be wanted according to business
Ask determination.It should be noted that set location of the through hole on tube wall is relevant with the quantity of through hole, and can at least exist following
Two kinds of situations：
Situation one：When the quantity of through hole is one, a through hole can be arranged on the optional position on tube wall；
Situation two：When the quantity of through hole is at least two, at least two through holes are equally distributed to be arranged on tube wall.
In addition, the perforate direction of through hole can towards the openend of guider, can also towards guider blind end.Its
The perforate direction of middle through hole towards the openend of guider be a kind of preferred perforate direction.The position of opening of through hole is to guider
The distance of openend can also be determined according to business need.
In the present embodiment, when reacting gas enters the body in guider tubular structure, the envelope of tubular structure
Closed end turns back the reacting gas of entrance, and is emitted into by the through hole on tubular structure tube wall the catalytic reaction zone of reactor.
When the blind end of tubular structure turns back the reacting gas of entrance, the energy that script can dissipate on distributor body is changed into
For the rotation function of reacting gas.Reacting gas with rotation function can maintain larger Jet Penetration Depth, make reacting gas
Bubble will not become big rapidly, keep minute bubbles high-frequency, so as to increase residence time of the reacting gas in catalytic reaction zone, reach
To the purpose for improving fluidization quality.
The guider 401 being illustrated in figure 4 in the front view of guider, figure is the circular tube shaped that a diameter c is 24 millimeters
Structure.Include the through hole that 4 diameter a are 2.5 millimeters on tube wall, and 4 through holes are evenly distributed on tube wall.Each through hole
Center line B2 and guider vertical axial center line B1 angle k be 44 °, and through hole position of opening to distributor body
Apart from b be 9 millimeters.The cavity diameter h of guider tubular structure is 5 millimeters of cylindrical cavity.
According to above-described embodiment, when entering the body in guider tubular structure due to reacting gas, tubular structure
Blind end turns back the reacting gas of entrance., can be by originally and the blind end of tubular structure is when the reacting gas of entrance is turned back
The energy dissipated on distributor body transforms into the rotation function of reacting gas, anti-in catalytic reaction zone due to entering
Gas is answered to carry rotation function, so improving residence time of the reacting gas in catalytic reaction zone.
In an embodiment of the invention, such as, guider is used for the reactor that hydrogenation of chloronitrobenzene prepares the 1wt/a of aniline
In, the Jet Penetration Depth of reacting gas wherein is increased due to having used guider in the preparation process, so that passing through distribution
The reaction gas flow of device is uniform so that reacting gas can carry out uniform violent reaction with catalyst, to reach effectively
Suppress catalyst defluidization or react the carbon distribution caused excessively.So that in crude benzol amine product after reactor is converted, nitrobenzene
Content is steady in a long-term in below 10mg/kg, so that catalyst regeneration cycle extended to 7-10 by original 3-4 months
Month.
According to above-described embodiment, due to reactor by guider after, the reaction gas with rotation function can be converted to
Body, increases the Jet Penetration Depth of reacting gas, so that uniform by the reaction gas flow of distributor so that reacting gas
Uniform violent reaction can be carried out with catalyst, to reach effectively suppression catalyst defluidization or react the carbon distribution caused excessively.
So as to extend the regeneration period of catalyst.
In an embodiment of the invention, as shown in figure 5, when distributor body be pipe distributor 501 when,
The blind end 5021 of the guider 502 towards the catalytic reaction zone top layer, by the through hole to rotate
The mode of jet transmits the reacting gas to the catalytic reaction zone.
In the present embodiment, Fig. 5 is that the low pressure drop high stability distributor that distributor body is pipe distributor is reacting
Position view in device 50, the guider being connected in figure with venthole in pipe distributor is a kind of signal.It is low in figure
Pressure drop high stability distributor need by the catalytic reaction zone in reactor according to the track L1 shown in figure in reactor
Bottom is circulated to the top of reactor.Therefore the through hole direction in the guider that will be connected with venthole on pipe distributor is needed
The top layer D1 of catalytic reaction zone, to make through hole transmit reacting gas to the top layer D1 of catalytic reaction zone in the way of rotating jet.
Reacting gas can drive catalyst to be flowed according to the track L1 shown in figure.
