Description

Technical Field

[0001] The utility model relates to the technical field of ferric chloride crystallization, in particular to a novel ferric chloride crystallizer. Background Art

[0002] Ferric chloride is a covalent inorganic compound. It typically appears as dark brown crystals, but can also form flakes. Ferric chloride is highly hygroscopic, absorbing moisture from the air and deliquescing. Ferric chloride crystallization typically occurs through cooling or evaporation. As the solution cools, ferric chloride molecules gradually aggregate to form nuclei, which then grow into crystals.

[0003] During the crystallization process, cooling and temperature reduction treatment is required through crystallization equipment. Existing crystallization equipment mostly uses simple heat exchange boxes and heat exchange fins for cooling and heat exchange. It cannot increase the contact time and contact area between the liquid and the cold medium, resulting in low heat exchange efficiency and inability to cool and crystallize faster. Utility Model Content

[0004] The purpose of the utility model is to provide a novel ferric chloride crystallizer to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a new ferric chloride crystallizer, comprising:

[0008] Preferably, a feed flange is fixedly connected to the top of one end of the cooling box body, and a discharge flange is fixedly connected to the bottom of the end of the cooling box body away from the feed flange.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 2 As shown in Figures 3 and 4, the utility model provides a technical solution: a new type of ferric chloride crystallizer, comprising: a cooling box body 1, the cooling box body 1 is a cavity with an inlet and outlet at both ends; four partition plates 6 are provided, two of which are installed on the upper and lower inner walls of the cooling box body 1, and the upper and lower two are staggered inside the cooling box body 1, for dividing the interior of the cooling box body 1 into an S-shaped channel, triangular plates 7 are fixedly connected on both sides of the partition plate 6, heat exchange spiral tubes 9 are fixedly connected inside the triangular plates 7, and pipes connected to the heat exchange spiral tubes 9 are embedded in the interior of the partition plate 6.

[0023] It should be noted that the utility model feeds the liquid to be crystallized into one end of the cooling box 1, and places the cooling medium, such as cooling water or cold air, in the partition plate 6. Under the action of the pipeline, and the partition plate 6 and the triangular plate 7 are both good conductors of cold, so that the partition plate 6, the triangular plate 7 and the heat exchange spiral tube 9 are all in a low-temperature state. Under the separation effect of the partition plate 6, the liquid to be crystallized travels along an S-shaped route inside the cooling box 1, so that it is in full contact with the cold medium. Under the action of the low temperature, the liquid crystallizes, and then the solid-liquid mixture is discharged from one end of the cooling box 1.

[0024] See also Figure 1 、 2 As shown, a feed flange 5 is fixedly connected to the top of one end of the cooling box body 1 , and a discharge flange 4 is fixedly connected to the bottom of the end of the cooling box body 1 away from the feed flange 5 .

[0025] It should be noted that the liquid to be crystallized in the present invention is connected to the feed flange 5 through a liquid inlet pipe, so that the liquid to be crystallized enters the cooling box 1 through the feed flange 5, and under the separation effect of the partition plate 6, heat exchange is carried out inside the cooling box 1, and then a solid-liquid mixture is formed and discharged from the discharge flange 4.

[0026] See also Figure 2 、 3 As shown, the triangular plates 7 on both sides of the partition plate 6 are rotated 180° about the center of the partition plate 6 and overlap each other. The triangular plates 7 are right-angled triangle structures, and a plurality of flow limiting holes 8 are opened on the inclined surface of the triangular plates 7.

[0027] It should be noted that, in the present invention, after the liquid to be crystallized enters the triangular plate 7, the flow-limiting hole 8 allows the liquid to fully contact the heat exchange coil 9. Then, under the pressure of the liquid inlet, the liquid enters the heat exchange coil 9 on the other side from the top of the partition plate 6, thereby circulating, increasing the contact area and time between the heat exchange coil 9, the triangular plate 7, and the partition plate 6. The aperture of the flow-limiting hole 8 is larger than the aperture of the crystal.

[0028] See also Figure 1 、 4 As shown, the partition plate 6 is made of a combination of two metal plates 16, and the pipelines are guide pipe 10 and guide pipe 2 11. Guide pipe 10 and guide pipe 2 11 are embedded and installed between the two metal plates 16. Guide pipe 10 and guide pipe 2 11 are respectively connected to the two ends of the heat exchange spiral tube 9. A plurality of S-shaped heat exchange pipes 12 are connected between guide pipe 10 and guide pipe 2 11. The heat exchange pipes 12 are embedded and installed between the two metal plates 16. A heat exchange medium inlet pipe 2 and a heat exchange medium outlet pipe 3 are fixed to the top of the cooling box 1. One end of guide pipe 10 is connected to the heat exchange medium inlet pipe 2, and one end of guide pipe 2 11 is connected to the heat exchange medium outlet pipe 3.

[0029] It should be noted that the heat exchange medium of the present invention enters the heat exchange medium inlet pipe 2 and then enters the guide pipe 10, and then enters the heat exchange pipe 12 and the heat exchange spiral pipe 9 respectively through the guide pipe 10. The heat exchange pipe 12 cools the metal plate 16, so that the metal plate 16 cools the liquid. The heat exchange spiral pipe 9 is in direct contact with the liquid for heat exchange crystallization. The heat exchange medium flows through the heat exchange pipe 12 and the heat exchange spiral pipe 9 and then enters the guide pipe 2 11, and then enters the heat exchange medium discharge pipe 3 through the guide pipe 2 11 and is discharged. It is connected to the refrigeration equipment and recycled after secondary refrigeration.

[0030] See also Figure 2 As shown, a drainage hole is provided at the bottom of the partition plate 6, a sealing plug 13 is installed inside the drainage hole, a connecting rod 14 is fixedly connected to the middle of the sealing plug 13, and a sealing cover 15 is fixedly connected to one end of the connecting rod 14, and the sealing cover 15 is threadedly connected to the cooling box body 1.

[0031] It should be noted that, after the crystallization is completed, the sealing cover 15 can be rotated and separated from the cooling box body 1, and then the connecting rod 14 is pulled by the sealing cover 15, and the sealing plug 13 is separated from the partition plate 6 through the connecting rod 14. At this time, the liquid blocked by the partition plate 6 can flow toward the discharge flange 4 through the drainage hole, thereby facilitating the cleaning and washing of the interior of the cooling box body 1.
