Description
Technical field
The utility model relates to the fixed bed reactors field of chemical plant installations, in particular, relates to a kind of axially-located bed reacting gas redistributor.
Background technology
Along with the development of petro chemical industry and the expansion of unit scale, the diameter of reactor constantly increases.Along with the increase of reactor diameter, uniform problem just one of key issue becoming engineering development of reactor inner fluid.
Fixed bed reactors efficiency depends primarily on gas flow uniform degree in reaction zone, and the optimal design of porch gas distributor is extremely important.In the course of the work, reaction gas enters reactor from top, after inlet gas distributor, enters beds and completes reaction, then collects discharge through outlet gas collector.Fluid distrbution in bed directly affects the processes such as heat and mass in bed and chemical reaction, and the reaction gas of uneven distribution is known from experience catalyst can not evenly and be fully utilized, thus reduces the efficiency of catalyst and reactor.
As described in Figure 1, for the original fixed bed catalytic oxidation reactor of original glycol catalytic oxidation synthesizing biformyl, a large amount of circulating current and strong turbulence is there is in air intake passage outside this single conical distributor, tangential speed component is much larger than radial velocity component, cause the non-monotonic change that circumferential pressure distributes, cause to enter and produce serious bias current after single conical distributor, thus cause the skewness of reacting gas.
So be necessary to adopt rational distribution of gas technology, thus improve the uneven distribution of air-flow in major diameter fixed bed reactors, improve the utilization rate of catalyst and reactor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of equally distributed axially-located bed reacting gas redistributor that can improve gas in large diameter fixed bed reactors.
For achieving the above object, the utility model provides following technical scheme: a kind of axially-located bed reacting gas redistributor, comprise redistributor body, described redistributor intrinsic single is tapered, comprise gas cutting portion, described gas cutting portion comprises multiple conical ring cutting sheet in conical ring with one heart, and the conical ring cutting sheet described in each all runs through in radial direction connection strap, and described connection strap is fixedly connected with each taper cutting sheet.
The utility model is set to further: the interior cone angle of described conical ring cutting sheet is 55-75 °.
The utility model is set to further: the spacing between described conical ring cutting sheet is 50-250mm.
The utility model is set to further: the height of described conical ring cutting sheet is 100-500mm.
Compared with prior art, the utility model has the advantage of: add a gas redistributor at axial flow fixed bed entrance, and redistributor includes gas cutting portion, and gas cutting portion comprises multiple concentric conical ring cutting sheet, thus the redistributor be made up of the conical ring cutting sheet of different number can be selected to mate according to the axial flow fixed bed entrance of different bore, this set makes type selecting convenient, gas before entering axial flow fixed bed entrance first through the redistributor of gas, owing to being wherein provided with multiple concentric conical ring cutting sheet, so gas is in redistributor, multiple part can be cut into uniformly, change gas shaped flow stream in bed and make the VELOCITY DISTRIBUTION of radial air flow be tending towards even, improve in prior art and there is a large amount of circulating current and strong turbulence in air intake passage outside single conical distributor, tangential speed component is much larger than radial velocity component, cause the non-monotonic change that circumferential pressure distributes, cause the phenomenon entering and produce serious bias current after single conical distributor.

Detailed description of the invention
Reference Fig. 1 is axially-located bed reacting gas distributor of the prior art, can see that gas enters from feed pipe 1, then be ejected into beds 4 by after inlet gas distributor 3, the gas then after reaction flows out from discharge nozzle 2 again, enters into next operation; Flowing gas bundle 5 from inlet gas distributor 3 to beds 4 can see it being skewness in FIG, a large amount of circulating current and strong turbulence is there is in air intake passage outside the inlet gas distributor 3 of this single taper, tangential speed component is much larger than radial velocity component, cause the non-monotonic change that circumferential pressure distributes, cause to enter producing serious bias current after single conical distributor.
With reference to Fig. 2 and Fig. 3, a kind of axially-located bed reacting gas redistributor 6 embodiment of the utility model is described further.
A kind of axially-located bed reacting gas redistributor 6, comprise redistributor 6 body, described redistributor 6 intrinsic single is tapered, comprise gas cutting portion, described gas cutting portion comprises multiple conical ring cutting sheet 61 in conical ring with one heart, conical ring cutting sheet 61 described in each all runs through in radial direction connection strap 62, described connection strap 62 is fixedly connected with each taper cutting sheet, the interior cone angle of described conical ring cutting sheet 61 is 55-75 °, spacing between described conical ring cutting sheet 61 is 50-250mm, and the height of described conical ring cutting sheet 61 is 100-500mm.
Best, the spacing 100-200mm of conical ring cutting sheet 61, height 200---300mm, interior cone angle is 60--70 °.
Gas cutting portion comprises multiple concentric conical ring cutting sheet 61, thus the redistributor 6 be made up of the conical ring cutting sheet 61 of different number can be selected to mate according to the axial flow fixed bed entrance of different bore, and this set makes type selecting convenient.
Can see that gas enters from feed pipe 1, then after entering into inlet gas distributor 3 after redistributor 6 again, be ejected into beds 4, the gas then after reaction flows out from discharge nozzle 2 again, enters into next operation; Because redistributor 6 is provided with multiple concentric conical ring cutting sheet 61, so gas is in redistributor 6, multiple part can be cut into uniformly, change gas shaped flow stream in bed and make the VELOCITY DISTRIBUTION of radial air flow be tending towards even, so flowing gas bundle 5 almost can evenly and the direction of vertical catalyst bed 4 penetrate, thus reacting gas and beds 4 can evenly and fully be utilized, thus improve the efficiency of catalyst and reactor.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
