[0002] The preparation process of sodium hydrosulfide flake solid in the petrochemical industry mainly uses 32% sodium hydrosulfide solution as raw material. The raw material is obtained by extracting hydrogen sulfide generated by acidic steam and solvent regeneration equipment and absorbing it with 32% sodium hydroxide solution. It contains many impurities, the main impurities of which are sodium carbonate, sodium sulfide and rust.

[0003] In the prior art, liquid sodium hydrosulfide is generally transported to the interior of an evaporation box through a delivery pipe and then formed inside a crystallization box. However, the position of the delivery pipe is fixed, and the liquid sodium hydrosulfide will continue to fall at one position in the crystallization box. This will cause the liquid sodium hydrosulfide to crystallize thicker at the location where it first contacts the crystal, forming a cone-shaped crystal. The crystal then spreads to the surrounding area, resulting in uneven crystallization. Therefore, a new sodium hydrosulfide flake forming device is needed to solve the above problem. Utility Model Content

The crystallization box is mounted inside the evaporation box by the positioning assembly, and the diverter plate is driven to move back and forth laterally by the drive assembly, so that liquid sodium hydrosulfide is sprayed inside the crystallization box through the nozzle.

[0006] Preferably, the elastic hose is arranged between the evaporation device housing and the evaporation box, and the elastic hose is sleeved on the guide rod.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] See also Figure 1-Figure 5The utility model provides an embodiment: a novel sodium hydrosulfide flake device, comprising an evaporation device housing 1, and also comprising a filter device 5 installed on the evaporation device housing 1, an evaporation box 21 fixedly connected to the inside of the evaporation device housing 1, a guide rod 22 fixedly connected to the inside of the evaporation box 21, a diverter plate 23 slidably connected to the guide rod 22, an elastic hose 24 fixedly connected to the diverter plate 23, a nozzle 25 installed at the bottom of the diverter plate 23, a crystallization box 26 slidably connected to the inside of the evaporation box 21, a driving component installed on the evaporation box 21 and the evaporation device housing 1, and a positioning component installed on the evaporation box 21 and the crystallization box 26. The crystallization box 26 is installed in the inside of the evaporation box 21 by the positioning component, and the diverter plate 23 is driven by the driving component to move back and forth laterally, so that liquid sodium hydrosulfide is sprayed on the flakes through the nozzle 25. Inside the crystal box 26, the filter device 5 is activated carbon and its modified materials, which adsorb small molecular odors, or purify the gas generated by evaporation through an external spray tower. The driving component causes the diverter plate 23 to slide back and forth on the guide rod 22, so that the nozzle 25 evenly sprays the liquid sodium hydrosulfide into the crystallization box 26, thereby heating it through the evaporation box 21, causing the liquid sodium hydrosulfide to evaporate and crystallize inside the crystallization box 26 at the same time. The purified gas is purified by the filter device 5, and the sealed door on the evaporation device housing 1 can be opened. The positioning of the crystallization box 26 is released by the positioning component, and then the crystallization box 26 is directly pulled out. A heating wire is provided inside the evaporation box 21 to heat the inside of the evaporation box 21 and control the problems inside the evaporation box 21. The temperature control and heating principle of the evaporation box 21 is the existing technology, so this application will not describe it in detail.

[0021] See also Figures 1-4In this embodiment, the elastic hose 24 is arranged between the evaporation device housing 1 and the evaporation box 21, and the elastic hose 24 is sleeved on the guide rod 22. The guide rod 22 positions the elastic hose 24 while positioning the diverter plate 23, preventing the elastic hose 24 from falling and contacting the liquid sodium hydrosulfide to avoid affecting the crystallization effect. The material of the elastic hose 24 is steel-lined with tetrafluoroethylene, which is resistant to high temperatures. An overflow hole 27 is provided on the crystallization box 26, and an overflow groove 28 is provided on the crystallization box 26 at the corresponding position of the overflow hole 27. After the liquid sodium hydrosulfide in the upper crystallization box 26 is full, the overflow can overflow through the overflow groove 28 and flow to the adjacent crystallization box 26 below, so that the liquid sodium hydrosulfide is crystallized in multiple crystallization boxes 26 and evenly distributed. The evaporation box 21 is provided with a positioning frame at the corresponding position of the crystallization box 26, and the crystallization box 26 is arranged inside the evaporation box 21 through the positioning frame to prevent the crystallization box 26 from tilting and positioning the vertical position of the crystallization box 26. The driving assembly includes a driving motor 41 fixedly connected to the evaporation device housing 1, and a threaded rod 42 fixedly connected to the output end of the driving motor 41. The threaded rod 42 is rotatably connected to the evaporation device housing 1 and the evaporation box 21. The diverter plate 23 is threadedly connected to the threaded rod 42. The driving motor 41 drives the threaded rod 42 to rotate in forward and reverse rotation, so that the diverter plate 23 moves back and forth laterally. The threaded rod 42 can be replaced with a bidirectional screw rod as needed to adapt to the diverter plate 23. The specific structure and principle of the bidirectional screw rod are existing technology, so it will not be described in detail.

[0022] See also Figure 3 、 Figure 5 In this embodiment, the positioning assembly includes a block 31 fixedly connected to the evaporator 21, a sliding seat 32 slidably connected to the crystallization box 26, a clamping rod 33 rotatably connected to the sliding seat 32, and a return spring 34 fixedly connected between the sliding seat 32 and the crystallization box 26. The block 31 cooperates with the clamping rod 33 to not only stably position the crystallization box 26, but also quickly disassemble the crystallization box 26, making installation and disassembly more convenient. The block 31 is provided with an adaptive slot at the corresponding position of the clamping rod 33, and the clamping rod 33 is clamped inside the slot.

[0023] When working, the elastic hose 24 is connected to the delivery pump to deliver the liquid sodium hydrosulfide to the inside of the diverter plate 23 through the elastic hose 24 and then sprayed out through the nozzle 25. The drive motor 41 is started to drive the threaded rod 42 to rotate. The threaded rod 42 rotates to drive the diverter plate 23 to move, and the liquid sodium hydrosulfide is evenly sprayed into the crystallization box 26 through the nozzle 25. The crystallization box 26 cooperates with the heating of the evaporation box 21 to achieve evaporation. When there is a lot of liquid sodium hydrosulfide, it overflows through the overflow hole 27 and flows along the overflow groove 28 into the adjacent crystallization box 26 below. Then, it is crystallized in multiple crystallization boxes 26. The crystallization box 26 is pulled out and the crystallization box 26 drives the card rod 33 through the sliding seat 32. The card rod 33 is squeezed out of the card slot of the card block 31 and the reset spring 34 is compressed at the same time. The reset spring 34 is used to reset the sliding seat 32. After the card rod 33 is out of the card slot, the crystallization box 26 can be easily pulled out and the internal crystallization flakes can be subsequently processed.

[0024] Through the above steps, the diverter plate 23 moves back and forth while spraying the liquid sodium hydrosulfide through the nozzle 25, so that it is evenly distributed inside the crystallization box 26, so that the thickness of the crystal flakes is uniform, thereby solving the problem that the liquid sodium hydrosulfide continues to fall in one position, resulting in uneven crystal thickness.
