Compared to prior art, trim ring described in the utility model can compress the top layer silk screen in fixed bed hydrogenation tower,
Prevent in hydrogen peroxide production process because misoperation, the reason such as seethe of Catalytic Layer cause throwing for silk screen.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of fixed bed hydrogenation tower described in the utility model；
Fig. 2 is the top view of fixed bed hydrogenation tower described in the utility model；
Fig. 3 is the front view of trim ring described in the utility model；
Fig. 4 is the top view of trim ring described in the utility model.
Embodiment
As depicted in figs. 1 and 2, Fig. 1 is the structural representation of fixed bed hydrogenation tower described in the utility model；Fig. 2 is this reality
With the top view of the new fixed bed hydrogenation tower.The fixed bed hydrogenation tower of trim ring described in the utility model, including tower body 1, enter
Liquid pipe 2, catalyst layer 3, screen 4, liquid trap 5, silk screen 6, inert ceramic balls layer 7 and trim ring 8；The feed tube 2 is at the top of tower body 1
Insertion；The bottom of tower body 1 offers liquid outlet, and the liquid trap 5 connects with the liquid outlet；The screen 4 is arranged on collection
The top of liquid device 5；The top of screen 4 is inert ceramic balls layer 7, and the upper and lower side of the inert ceramic balls layer 7 lays one layer of silk screen respectively
6；The top of inert ceramic balls layer 7 is catalyst layer 3；A top layer silk screen 61 is laid on the catalyst layer 3, the top layer silk screen
61 be the straight barrel type of opening upwards, lays an inert ceramic balls layer 7 thereon；Top layer silk screen 61 is pressed on tower body 1 by the trim ring 8
Inwall on, in the present embodiment, the catalyst layer 3 is palladium chtalyst oxidant layer, and the silk screen 6 is steel wire.
Specifically, as shown in Figure 3 and Figure 4, Fig. 3 is the front view of trim ring described in the utility model；Fig. 4 is the utility model
The top view of the trim ring.The trim ring 8 is rigid circle body, is spliced mutually by least two sections and formed.Between each section of the trim ring 8
Connecting method have it is a variety of, can be fastened to each other by clamping, can also be fastened to each other by bolt.It is described in the present embodiment
Trim ring 8 divides for three sections.
In order to further improve antijamming capability, can be also provided with the trim ring 8 it is some lean on post 81, it is described to lean on post 81
Extended axially upward out along the edge of circle body, it is described to be close to tower body inwall by post 81.It is described to lean on post including at least three, it is described
It is evenly distributed on by post 81 on the circumference of trim ring 8.In the present embodiment, including three are leaned on post 81, are separately positioned on each section of circle
On body.
Operation principle：Inside hydrogen peroxide production process, the course of reaction in the tower stage is hydrogenated is, by alkyl-anthraquinone solution
The in the mixed solvent being made up of aromatic hydrocarbons and trioctyl phosphate is dissolved in, working solution, working solution and hydrogen is configured to and enters from top
Hydrogenation tower equipped with catalyst, anthraquinone react generation hydrogen anthraquinone under the catalytic action of catalyst with hydrogen.
In fixed bed, the main function of the porcelain ball of catalyst layer upper berth pressure makes to be compacted fix by catalyst layer, avoids it
Stir, in addition, also avoiding liquid directly washing away to catalyst.If porcelain ball stays, very big infringement can be caused to catalyst,
And the reason for causing porcelain ball to stay have it is a variety of, in the case where can easily cause toppling property of silk screen in the case that catalyst distribution is uneven
Sliding, now, the protective layer missing of porcelain ball can stay.Further, since silk screen is not paved whole, particularly edge does not press,
Porcelain ball is also resulted in leak down.In addition, silk screen can also be lifted as misoperation causes to produce excessive gas and buoyancy in course of reaction
Turn over, cause porcelain ball to stay.
And after trim ring 8 described in the utility model is installed, trim ring 8 can be being curled into through-type top layer silk screen 61
The inwall of tower body 1 is pressed on, enhances the fixing of inert ceramic balls layer 7, and vertical being played by post 81 supports what is stopped on trim ring 8
Effect, it can prevent trim ring 8 from being tilted when receiving external force to one party.
Compared to prior art, trim ring described in the utility model can prevent from hydrogenating silk screen in tower course of reaction and throw,
Porcelain ball is steadily fixed on silk screen, Catalytic Layer is compacted fix, and the fixed bed hydrogenation tower for applying the trim ring is avoided that
The situation that course of reaction porcelain ball stays occurs, and improves production efficiency.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.
