The number of mouth 111 is relevant with air inflow, and the setting of the number of air inlet 111 can be carried out according to air inflow.
Preferably, air inlet 111 is even number and is relatively arranged on reactor body 110, and gas is in symmetrically to enter gas
In body space 123, i.e., water conservancy diversion preheating table 120 and inwall are formed gap carries out septate heat transfer, afterwards with water conservancy diversion preheating table 120
Downwardly into distribution grid 130 with being distributed in advance in the bottom space of collecting tank 140, finally upwardly through multihole distributor
130 distribution hole 131, which is entered in the liquid phase in reactor, to be reacted, and makes the preheating of gas more uniform, and charging is more equal
It is even, make the reaction effect in reactor body 110 more preferable.
The shape of water conservancy diversion preheating table 120 is relevant 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 water conservancy diversion preheating table 120 is smaller than the size of reactor body 110, i.e.
Water conservancy diversion preheating table 120 is arranged in reactor body 110, and forms gap between the inwall 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 inwall 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 is located at the lower end of water conservancy diversion preheating table 120, and hang plate 122 is located at water conservancy diversion preheating
The upper end of plate 120, one end of the remote hang plate 122 of vertical plate 121 are connected with distribution grid 130, hang plate 122 away from vertical
One end of plate 121 is connected with the inwall of reactor body 110.In this way, make whole 100 each part of gas feed distributor it
Between connection it is more firm.Meanwhile air inlet 111 enters after the gas compartment 123, can be stopped at hang plate 122, then
Towards distribution grid 130 direction move, have a downward eddy-currents, make gas flowed in the whole gas compartment 123 after from
Enter liquid phase in the distribution hole 131 of distribution grid 130, make the pre-heat effect of gas more preferable, also, enter the later distribution of liquid phase more
Add uniformly.
In the present embodiment, the gap of water conservancy diversion preheating table 120 and the inwall of reactor body 110 is 30-50mm, and this gap is set
Putting 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 be flowed and fed at distribution hole 131.
Preferably, the height of water conservancy diversion preheating table 120 and the internal diameter ratio of reactor body 110 are (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 space-consuming of state bed reactor
It is relatively small, beneficial 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, discharging tube 150 are arranged at the tip of tapered collecting tank, are advantageous to the discharge of leakage.Preferably, the cone of tapered collecting tank
Angle α between face and horizontal plane is 3-20 °, makes 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 support beam 161 and multiple support columns 162, and the both ends of support beam 161 may be contained within tapered liquid collecting
Groove 140, one end of each support column 162 are arranged at distribution grid 130, and the other end is arranged at support beam 161.Support beam 161 and branch
The setting of dagger 162, support is played a part of to distribution grid 130, can be very good to avoid distribution grid 130 from deforming, increase distribution
The service life of plate 130.
Preferably, the distance between support 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 groove and horizontal plane is relevant, and angle α is smaller, and apart from smaller, angle α is bigger, bigger, this distance of distance
Setting can make the support effect of distribution grid 130 more preferable, and the edge of distribution grid 130 can be supported.
