Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of benzene processing, in particular to a benzene deep refining system in a caprolactam production process. Background Art
[0002] Benzene is a hydrocarbon, the simplest aromatic hydrocarbon. At room temperature, it is a sweet, flammable, carcinogenic, colorless, transparent liquid with a strong aromatic odor.
[0003] Since benzene is poorly soluble in water, in the production of caprolactam, the benzene is separated and mixed with water to make it float on the water, and then it is processed and collected, which can improve the safety and effect of the processing. However, in actual processing, due to the sealing of the device itself, the extraction device is difficult to move due to pressure when deep processing of benzene is carried out, and the benzene at different depths cannot be refined, which affects the processing efficiency of the device and is extremely inconvenient to use. For this reason, we propose a deep refining system for benzene in the caprolactam production process. Utility Model Content

[0005] Preferably, a fixed support plate is installed on the upper end of the fixed shell, and an extraction pipe is installed on the upper end of the fixed support plate, and the extraction pipe is used for the circulation of benzene.
[0006] Preferably, an adjustment support plate is installed on the outer side of the height flow pipe, the extraction pipeline is located in the middle of the adjustment support plate, and a fastening bolt is installed on the outer side of the adjustment support plate, and the fastening bolt is used to fix the extraction pipeline.
[0007] Preferably, a storage device is installed at one end of the extraction pipe away from the adjustment support plate, a fixed base is installed at the lower end of the storage device, and the fixed shell is located above the fixed base.

[0009] Preferably, a mobile storage box is installed at the lower end of the fixed base, and the lower end of the mobile discharge pipe is located inside the mobile storage box.
[0010] Beneficial effects:
[0011] 1. In the benzene deep refining system of the caprolactam production process, when it is necessary to process benzene of different depths, the staff moves the mobile discharge pipe downward, so that the connecting support plate drives the height circulation pipe to move downward at the same time, so that the benzene inside the device flows to the surface of the connecting support plate through the circulation effect of the height circulation pipe. At the same time, the mobile discharge pipe moves under the support of the sliding port, so that the raw materials below the device flow to the inside of the mobile discharge pipe through the circulation port and are discharged to the outside of the device. The connecting support plate is moved again to make benzene of different depths flow out through the circulation of the height circulation pipe, so that the raw materials below do not affect the degree of downward movement of the device, effectively separating benzene and other raw materials, and achieving the effect of refining benzene of different depths.

When it is necessary to process benzene of different depths, the staff can lower the mobile discharge pipe 1 by moving the mobile discharge pipe 1 downward. The connecting support plate 2 is moved so that the height circulation pipe 6 is moved downward at the same time, so that the benzene inside the device flows to the surface of the connecting support plate 2 through the circulation action of the height circulation pipe 6. At the same time, the mobile discharge pipe 1 moves under the support of the sliding port 5, so that the raw materials below the device flow to the inside of the mobile discharge pipe 1 through the circulation port 3 and are discharged to the outside of the device. The connecting support plate 2 is moved again to make benzene at different depths flow out through the circulation of the height circulation pipe 6, so that the raw materials below do not affect the degree of downward movement of the device, effectively separating benzene and other raw materials, and achieving the effect of refining benzene at different depths.
[0022] Among them, a fixed support plate 7 is installed on the upper end of the fixed shell 4, and an extraction pipe 8 is installed on the upper end of the fixed support plate 7. The extraction pipe 8 is used for the circulation of benzene. When the benzene in the device is extracted, the extraction pipe 8 is adjusted accordingly through the support of the fixed support plate 7, so that the benzene can flow stably to the outside of the device under the support of the extraction pipe 8.
[0023] Among them, an adjustment support plate 10 is installed on the outside of the height flow pipe 6, the extraction pipe 8 is located in the middle of the adjustment support plate 10, and a fastening bolt 11 is installed on the outside of the adjustment support plate 10. The fastening bolt 11 is used to fix the extraction pipe 8. When benzene of different depths needs to be processed, the extraction pipe 8 is moved downward under the support of the adjustment support plate 10, and then the fastening bolt 11 is tightened to achieve the effect of stabilizing the position of the extraction pipe 8.
[0024] Among them, a storage device 9 is installed at one end of the extraction pipe 8 away from the adjustment support plate 10, a fixed base 14 is installed at the lower end of the storage device 9, and the fixed shell 4 is located above the fixed base 14. Through the storage and extraction function of the storage device 9 for benzene, it is ensured that the benzene extracted from the fixed shell 4 can stably flow into the storage device 9 under the guidance of the extraction pipe 8, thereby ensuring the safe processing of benzene.

The support column 13 is located at the lower end of the fixed shell 4. When the connecting support plate 2 moves, the telescopic rod 12 moves simultaneously under the sliding support of the support column 13, thereby achieving the effect of stably supporting the connecting support plate 2.
[0026] Among them, a mobile storage box 15 is installed at the lower end of the fixed base 14, and the lower end of the mobile discharge pipe 1 is located inside the mobile storage box 15.

[0027] When the system is working, Figure 3 As shown, when benzene at different depths needs to be processed, the staff moves the mobile discharge pipe 1 downward, so that the connecting support plate 2 drives the height circulation pipe 6 to move downward at the same time, so that the benzene inside the device flows to the surface of the connecting support plate 2 through the circulation action of the height circulation pipe 6. At the same time, the mobile discharge pipe 1 moves under the support of the sliding port 5, so that the raw material below the device flows to the inside of the mobile discharge pipe 1 through the circulation port 3 and is discharged to the outside of the device. The connecting support plate 2 is moved again to make benzene of different depths flow out through the circulation of the height circulation pipe 6, so that the raw material below does not affect the degree of downward movement of the device, effectively separating benzene and other raw materials, and achieving the effect of refining benzene at different depths.
