It is distributed in advance with the bottom space of collecting tank 140 downwardly into distribution grid 130, finally upwardly through multihole distributor
130 distribution hole 131, which enters in the liquid phase in reactor, to be reacted, and keeps the preheating of gas more uniform, and charging is more equal
It is even, keep the reaction effect in reactor body 110 more preferable.
The shape of water conservancy diversion preheating table 120 is related with the shape of reactor body 110, it is preferable that the shape of water conservancy diversion preheating table 120
Shape is consistent with the shape of reactor body 110, and the size of the size ratio reactor body 110 of water conservancy diversion preheating table 120 is small, that is,
Water conservancy diversion preheating table 120 is arranged in reactor body 110, and forms gap between the inner wall of reactor body 110, for supplying
The circulation of gas.
In the present embodiment, reactor body 110 is column, and water conservancy diversion preheating table 120 in a ring, in certain slope weld by upper end
In the inner wall of reactor body 110, lower end is welded on distribution grid 130.In detail, water conservancy diversion preheating table 120 includes being connected with each other
Vertical plate 121 and hang plate 122, vertical plate 121 be located at the lower end of water conservancy diversion preheating table 120, hang plate 122 is located at water conservancy diversion preheating
One end of the upper end of plate 120, the separate hang plate 122 of vertical plate 121 is connect with distribution grid 130, hang plate 122 far from vertical
One end of plate 121 is connect with the inner wall of reactor body 110.In this way, make 100 each component of entire gas feed distributor it
Between connection it is more secured.Meanwhile air inlet 111 enters after the gas compartment 123, can be stopped at hang plate 122, then
Moved towards the direction of distribution grid 130, there are one downward eddy-currents, after so that gas is flowed in the entire gas compartment 123 from
Enter liquid phase in the distribution hole 131 of distribution grid 130, keep the pre-heat effect of gas more preferable, also, enters the later distribution of liquid phase more
Add uniformly.
In the present embodiment, water conservancy diversion preheating table 120 and the gap of the inner wall of reactor body 110 are 30-50mm, and this gap is set
Setting can make the heat-transfer effect of water conservancy diversion preheating table 120 more preferable, and the pre-heat effect of gas is more preferable, also, the gas in the gas compartment 123
Body flow effect is also more preferable, in intake process, can have more gas to carry out flowing and be fed from distribution hole 131.
Preferably, the internal diameter ratio of the height of water conservancy diversion preheating table 120 and reactor body 110 is (0.2-0.3)：1.Make gas
Space 123 is larger, there is sufficiently large heat exchange area, and the pre-heat effect of gas is better, also, by the occupied space of state bed reactor
It is relatively small, it is conducive to the installation of production equipment.
Fig. 4 is the enlarged drawing at IV in Fig. 1.Also referring to Fig. 1-Fig. 4, in the present embodiment, collecting tank 140 is tapered collection
Liquid bath, drain pipe 150 are set at the tip of tapered collecting tank, are conducive to the discharge of leakage.Preferably, the cone of tapered collecting tank
Angle α between face and horizontal plane is 3-20 °, keeps the collecting effect of leakage preferable, also, tapered collecting tank occupancy is relatively small
Space, facilitate the manufacture of gas feed distributor 100.
Reinforcer 160 includes supporting beam 161 and multiple support columns 162, and the both ends of supporting beam 161 may be contained within tapered liquid collecting
One end of slot 140, each support column 162 is set to distribution grid 130, and the other end is set to supporting beam 161.Supporting beam 161 and branch
The setting of dagger 162 plays the role of support to distribution grid 130, can be very good that distribution grid 130 is avoided to deform, increases distribution
The service life of plate 130.
Preferably, the distance between supporting beam 161 and distribution grid 130 are 30-50mm, the setting of this distance and tapered liquid collecting
Angle α between the conical surface of slot and horizontal plane is related, and angle α is smaller, and apart from smaller, angle α is bigger, bigger, this distance of distance
Being arranged can make the support effect of distribution grid 130 more preferable, can be supported to the edge of distribution grid 130.
