Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment, in particular to diphenyl dimethyl ether water-material separation equipment. Background Art
[0002] Dimethyl biphenyl ether is an odorless, tasteless white crystal, which is mainly used for the synthesis of flame retardant resins, especially the synthesis of liquid crystal polymers. At present, there is a synthesis process of dimethyl biphenyl ether, which fully reacts methanol and alkali in a reactor, and then adds diphenyl dichloride to the reactor. After the reaction is completed, water and an extraction solvent are added to the mixed solution, and the mixture is stirred fully to separate the organic phase from the aqueous phase of the mixed solution, and the aqueous phase is discharged. Water is continuously added to the organic phase for several washings. After each washing, the aqueous phase at the lower layer needs to be drained. After washing, an organic phase can be obtained, and the extraction solvent in the organic phase is recovered to obtain dimethyl biphenyl ether.
[0003] In order to better separate the water phase and the oil phase in the process of producing dimethyl biphenyl ether, the staff usually transfers the mixed solution in the reactor to the equipment for water-material separation, allows the mixed solution in the chamber of the water-material separation equipment to stand, and then discharges the water phase from the bottom of the water-material separation equipment to achieve water-material separation. Since the chamber of the mixed solution contains more mixed solution, the mixed solution needs a longer standing time, and the released water phase is usually doped with the organic phase, resulting in waste of the organic phase. In response to the above phenomenon, the inventors have invented a new type of hydrotherapy separation equipment for the production of dimethyl biphenyl ether to improve work efficiency and reduce waste of organic phase. Utility Model Content

[0007] A horizontally placed cylinder, wherein a chamber is provided in the cylinder, a feed pipe is provided on one side wall of the length direction of the cylinder, a liquid discharge pipe is provided at the bottom end of the cylinder, and a valve is installed on the wall of the liquid discharge pipe;
[0008] Partitions are provided in multiple groups, and the multiple groups of partitions are arranged at the bottom of the chamber along the length direction of the cylinder, and the height of the partitions away from the feed pipe is gradually reduced. The bottom end of the chamber is partitioned by multiple groups of partitions to form multiple groups of static chambers.
[0009] Preferably, a drainage cylinder is provided at the bottom end of the cylinder body, and the drainage cylinder is provided in multiple groups. The cylinder body of the drainage cylinder gradually shrinks from top to bottom, and the multiple groups of drainage cylinders are connected to the multiple groups of static chambers in a one-to-one state. The drainage tube is provided in multiple groups, and the drainage tube is provided at the bottom end.
[0010] Preferably, the ends of the plurality of groups of drainage tubes away from the drainage cylinder are interconnected.

[0015] Preferably, the plurality of groups of partitions are all inclined toward the direction of the feed pipe.
[0016] In summary, the utility model includes the following beneficial technical effects:
[0017] 1. The mixed solution to be extracted is transferred into the chamber through the feed pipe. The chamber is divided into multiple static chambers by multiple groups of partitions, and the height of the partitions away from the feed pipe is gradually reduced. The mixed solution first enters the static chamber close to the feed pipe, and the mixed solution in the static chamber close to the feed pipe overflows the partition and enters the next static chamber. In this process, the mixed solution in the static chamber close to the feed pipe has already shown stratification of aqueous phase and organic phase, so that most of the organic phase flows to the next static chamber, that is, the volume of the organic phase in the static chamber away from the feed pipe accounts for a large proportion. After the mixed solution in the static chamber completes stratification, the stratified aqueous phase and organic phase can be discharged from the drain pipe. This structure divides the chamber into multiple groups of static chambers to achieve the simultaneous stabilization of the mixed solution in each static chamber, thereby improving work efficiency and enhancing separation effect.
[0018] 2. By setting up a liquid drain cylinder, the cylinder body of which gradually shrinks from top to bottom, it is helpful to discharge the water phase located at the lower layer.
[0019] 3. By setting a buffer cover and forming an opening between the buffer cover and the chamber wall, the mixed solution entering from the feed port flows from the opening into the static chamber, thereby reducing the phenomenon of the mixed solution splashing into the static chamber and reducing the impact on the stratification process of the mixed solution in the static chamber.

[0023] The following is combined with Figure 1-2 The utility model is described in further detail.
[0024] The utility model embodiment discloses a diphenyl dimethyl ether water material separation device. Figure 1 and Figure 2 , including a cylinder 1, which is placed horizontally, with a chamber 11 opened inside the cylinder 1, a side wall at one end in the length direction of the cylinder 1 is connected to a feed pipe 12 communicating with the chamber 11, a bottom end of the cylinder 1 is connected to a discharge pipe 13 communicating with the chamber 11, and a valve 131 is installed on the wall of the discharge pipe 13; a plurality of groups of partitions 2 are arranged in the chamber 11, the plurality of groups of partitions 2 are arranged along the length direction of the cylinder 1 and welded to the bottom of the chamber 11, and the height of the partitions 2 away from the feed pipe 12 is gradually reduced, the bottom end of the chamber 11 is partitioned by the plurality of groups of partitions 2 to form a plurality of groups of static chambers 111, and the partitions 2 in this embodiment are optimally arranged with two groups, that is, three groups of static chambers 111 are formed in the chamber 11.
[0025] Reference Figure 1 and Figure 2 The bottom end of the cylinder body 1 is connected with a drainage cylinder 3, and the drainage cylinder 3 is provided with multiple groups. The drainage cylinder 3 in this embodiment is optimally provided with three groups, and the cylinder body 1 of the drainage cylinder 3 gradually decreases from top to bottom, and the three groups of drainage cylinders 3 are respectively connected with the three groups of static chambers 111. At the same time, there are multiple groups of drainage pipes 13. Three groups of drainage pipes 13 in this embodiment are provided, and the three groups of drainage pipes 13 are respectively connected to the bottom ends of the drainage cylinder 3. Lenses 14 are respectively provided on the side walls of the cylinder body 1 and the drainage cylinder 3 to facilitate the staff to observe the situation of the mixed solution in the chamber 11 and the drainage cylinder 3, and by setting the drainage cylinder 3 to a constricted shape, it is convenient to discharge the aqueous phase located at the lower layer of the mixed solution from the drainage cylinder 3; in this embodiment, the three groups of drainage pipes 13 are in a state of being interconnected at one end away from the drainage cylinder 3, that is, the valves 131 on the three groups of drainage cylinders 3 are opened at the same time, and the solutions in the three groups of static chambers 111 can be discharged from the chamber 11 at the same time.
[0026] Reference Figure 2A buffer cover 4 is fixedly connected to the wall of the chamber 11, and the buffer cover 4 is in a state of covering one end of the feed pipe 12 located in the chamber 11. An opening 41 is formed between the buffer cover 4 and the wall of the chamber 11. The mixed solution entering the chamber 11 from the feed port flows from the opening 41 to the static chamber 111. The buffer cover 4 has a buffering effect on the mixed solution, thereby reducing the phenomenon of the mixed solution splashing into the static chamber 111, and reducing the influence of the mixed solution in transportation on the mixed solution being stratified in the static chamber 111; and the height of the opening 41 is less than the height of the partition 2 close to the feed pipe 12, so that the mixed solution in the static chamber 111 close to the feed pipe 12 can normally overflow the partition 2, and will not affect the phenomenon of the feed pipe 12 transporting the mixed solution into the chamber 11.
[0027] Reference Figure 2 The wall of the chamber 11 provided with the feed pipe 12 is a curved surface, that is, the cross-section of the wall of the chamber 11 provided with the feed pipe 12 gradually increases from top to bottom, and the mixed solution flowing from the opening 41 to the chamber 11 follows the curved wall of the chamber 11 to enter the static chamber 111, further reducing the influence of the flowing mixed solution on the mixed solution being stratified in the static chamber 111; at the same time, the multiple groups of partitions 2 are all inclined toward the direction of the feed pipe 12, that is, the mixed solution overflowing the partition 2 follows the inclined partition 2 to enter the next group of static chambers 111, reducing the splashing phenomenon of the mixed solution, thereby accelerating the stratification effect and speed of the mixed solution in the static chamber 111.
[0028] The implementation principle of the dimethyl biphenyl ether water material separation equipment of the utility model embodiment:
[0029] The mixed solution to be layered that enters the chamber 11 from the feed pipe 12 enters the static chamber 111 along the curved wall of the chamber 11. As the mixed solution continues to increase, the mixed solution in the static chamber 111 near the feed pipe 12 overflows the partition 2, and the overflowed mixed solution enters the next static chamber 111 along the inclined partition 2. During this process, the mixed solution in the static chamber 111 near the feed pipe 12 has already shown the phenomenon of aqueous phase and organic phase stratification, so that most of the organic phase in the mixed solution flows to the next static chamber 111, that is, the volume of the organic phase in the static chamber 111 away from the feed pipe 12 accounts for a large proportion, and the bottom ends of the static chambers 111 are respectively connected to drainage tubes 3, and the drainage tubes 13 are connected to the bottom ends of the drainage tubes 3 to discharge the aqueous phase and organic phase that have been layered. By dividing the chamber 11 into multiple groups of static chambers 111, the mixed solutions in each static chamber 111 can be allowed to stand still at the same time, thereby improving the work efficiency and enhancing the separation effect.
[0030] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
