Abstract
A chlorine gas distributor comprises a horizontal main pipeline (1), wherein three auxiliary pipelines (2) (a long pipeline in the middle and two short pipelines on the two sides) are connected onto each of the two sides of the main pipeline; two air inlet pipes (3) are connected with the upper wall of the main pipeline; connecting flanges (4) are connected to the upper ends of the gas inlet pipes (3); gas distribution holes (5) are distributed uniformly on the pipe walls of the main pipeline and the six auxiliary pipelines; and blind plates (8) are arranged at the two ends of the main pipeline and the free ends of the six auxiliary pipelines. The chlorine gas distributor is arranged in a phosphorus trichloride reaction kettle, and two air inlet pipes are connected with a chlorine gas pipeline, so that chlorine gas can be inputted for reaction; chlorine gas flows out from the gas distribution holes and is distributed uniformly in the reaction kettle, so that the reaction process is smooth and steady, and phosphorus pentachloride is avoided generating due to partial excessive chlorine gas; and meanwhile, the amount of free phosphorus entering a phosphorus washing tower is reduced, so that the product quality is improved, partial violent reaction is avoided, and the shock of equipment is lightened.
Description
Technical field
The utility model relates to a kind of phosphorus trichloride production unit, a kind of chlorine gas distributor.
Background technology
In the present domestic phosphorus trichloride production process, logical chlorine operation still adopts primary chlorine rectilinear duct to lead to chlorine, though pipeline is not easy to stop up, but logical chlorine is inhomogeneous, cause a large amount of free phosphorus to enter and wash the phosphorus tower, free phosphorus content height influences product quality in the product; And the reaction process part is too violent, and it is very big to cause the equipment vibrations, make residual assorted the entering of big quantitative response wash the phosphorus tower, even production faults such as tower is blocked up in generation.
Summary of the invention
The utility model is intended to propose be used in a kind of phosphorus trichloride production the device of logical chlorine, and a kind of chlorine gas distributor can make that chlorine is evenly distributed in the reaction process, avoids local vigorous reaction.
This chlorine gas distributor comprises the main pipe line of a horizontal direction, the both sides of main pipe line are respectively connecting three secondary duct, secondary duct is stretched out to horizontal direction, and perpendicular with main pipe line, in three secondary duct of every side, one of intermediary is longer, two of both sides are shorter, the upper wall of main pipe line is connecting two inlet pipe, and inlet pipe is stretched out vertically upward, and respectively there is a joint flange two upper ends of carrying out tracheae.Be uniform-distribution with qi-emitting hole on the tube wall of main pipe line and six roots of sensation secondary duct, the free end of the two ends of main pipe line and six roots of sensation secondary duct respectively has a blind plate.
This chlorine gas distributor is installed in the phosphorus trichloride reactor, and two inlet pipe are connected with the Chlorination tube road by joint flange.Chlorine flows out from the main pipe line of chlorine gas distributor and the qi-emitting hole on the secondary duct, uniform distribution in reactor, make reaction process steady, it is excessive to have stopped local chlorine, avoided the generation phosphorus pentachloride, reduced a large amount of free phosphorus simultaneously and enter and wash the phosphorus tower, thereby improved product quality, avoid local vigorous reaction, reduced the vibrations of equipment.

Embodiment
As depicted in figs. 1 and 2, this chlorine gas distributor comprises the main pipe line 1 of a horizontal direction, is respectively connecting three secondary duct 2 in the both sides of main pipe line, secondary duct is stretched out to horizontal direction, and perpendicular with main pipe line, in three secondary duct of every side, one of intermediary is longer, and two of both sides are shorter.The upper wall of main pipe line is connecting two inlet pipe 3, and inlet pipe is stretched out vertically upward, and respectively there is a joint flange 4 two upper ends of carrying out tracheae.Be uniform-distribution with qi-emitting hole 5 on the tube wall of main pipe line and six roots of sensation secondary duct, the free end of the two ends of main pipe line and six roots of sensation secondary duct respectively has a blind plate 8.
As shown in Figure 2, the envelope curve of main pipe line in this chlorine gas distributor and secondary duct pipe end and the cross-sectional shape of reactor are close, make the qi-emitting hole uniform distribution in reactor on main pipe line and the secondary duct, carry out gas distribution with this chlorine gas distributor, can guarantee that gas distribution is even, thereby make reaction process steady.The use of this chlorine gas distributor is installed in the bottom of phosphorus trichloride reactor 12 with chlorine gas distributor 11 as shown in Figure 3, and two inlet pipe 3 are connected with Chlorination tube road 10 by joint flange, can import chlorine and react.When maintenance, can rely on flange that chlorine gas distributor is pulled down, keep in repair separately.
As shown in Figure 1, also can respectively there be a qi-emitting hole 9 at the center of the free-ended blind plate of the six roots of sensation secondary duct of this chlorine gas distributor.
The thinner elongation arm 6 that can in succession one section and stretch out downwards under main pipe line 1 middle part of this chlorine gas distributor, the lower ending opening of elongation arm.This elongation arm is to be used for making the yellow phosphorus of reactor bottom to obtain competent chlorine, guarantees that clear pot phosphorus reaction of the preceding end is thorough.
This chlorine gas distributor can be made of stainless steel tube and stainless steel plate, and its reference dimension is:
Main pipe line 1:DN80, wall thickness 4.0mm, long 1.4 meters;
Secondary duct 2:DN80, wall thickness 4.0mm, wherein 2 long 0.4 meter, 4 are long 0.3 meter;
Inlet pipe 3:DN80, wall thickness 4.0mm, long 0.4 meter;
Elongation arm 6:DN20, wall thickness 2.5mm, long 0.05 meter;
Flange 4:DN80, PN16, RF;
Blind plate 8: wall thickness 5.0mm;
The qi-emitting hole of 4 Φ 20mm is opened in main pipe line below, main pipe line two sides and directly over respectively open the qi-emitting hole of 10 Φ 10mm; Respectively open the qi-emitting hole of 8 Φ 12mm around long 0.3 meter the secondary duct; Respectively open the qi-emitting hole of 12 Φ 12mm around long 0.4 meter the secondary duct; Open the qi-emitting hole of Φ 12mm on the blind plate of secondary duct end.
The chlorine gas distributor of above-mentioned size is applicable to that volume is the reactor of 5M3.
