Description

Technical Field

[0001] This utility model relates to the field of recycling equipment technology, and in particular to a resource recycling device for sodium sulfide waste alkali solution. Background Technology

[0002] Waste alkali solution is a waste liquid containing a large amount of pollutants generated during petrochemical production processes, specifically during the absorption of H2S with NaOH solution, alkali washing of oil products, and cracking of gases. Because it contains inorganic and organic sulfides such as sulfides and thiols, waste alkali solution has a foul, unpleasant odor. The reuse of sodium sulfide waste alkali solution can be achieved in various ways, the most common being evaporation and concentration: by heating and evaporating the water in the waste liquid, the sodium sulfide crystals are recovered after concentration.

[0003] Traditional sodium sulfide waste alkali liquid resource recovery devices usually directly use heating to evaporate water and recover the evaporated sodium sulfide crystals. However, in actual use, when some lighter media are evaporated and crystallized, some crystal powder will be carried away by the water vapor after evaporation, which will affect the recovery efficiency of sodium sulfide crystals. Utility Model Content

[0004] The main purpose of this utility model is to provide a resource recovery device for sodium sulfide waste alkaline solution, which aims to solve the technical problem that when some lighter media are evaporated and crystallized, the crystal powder in the water vapor after evaporation is carried away by the water vapor, thus affecting the recovery efficiency of sodium sulfide crystals.

A second flow channel is opened inside the separator and is located at the top of the partition. The mounting plate is installed inside the recycling bin. The mounting column is fixedly installed at the bottom of the mounting plate and is located between one side of the separator and the inner wall of the recycling bin. The extension is fixedly installed on the side wall of the mounting column.

[0007] Furthermore, a plurality of mounting posts and a plurality of extension members are provided.

[0008] Furthermore, the top of the recycling bin is provided with an installation groove, and the installation plate is snapped into the installation groove.

[0009] Furthermore, the mounting column has a mounting component slidably connected to its side wall, the mounting component has an inner wall with a mounting cavity, a spring is fixedly installed on the inner wall of the mounting cavity, and a snap-fit ​​component is fixedly installed on one end of the spring.

[0010] Furthermore, the mounting column has a snap-fit ​​groove on its side wall, which fits into the snap-fit ​​component. A scraper is fixedly installed at the bottom of the mounting component, and the scraper is in contact with the side wall of the mounting column.

[0011] Furthermore, an electric heating wire is fixedly installed on the side wall of the partition, and the electric heating wire is located at the bottom of the partition.

[0012] Furthermore, a mounting rod is fixedly mounted on the top of the mounting plate.

[0016] Beneficial effects:

[0017] The present invention relates to a resource recovery device for sodium sulfide waste alkaline solution, the beneficial effects of which are as follows:

[0018] 1. By setting up a partition frame, the water vapor generated during the evaporation of sodium sulfide waste alkali liquid inside the recovery box can circulate inside the recovery box through the first and second flow channels. This allows the water vapor to frequently come into contact with the mounting columns on the outside of the partition frame. Through the extension of the side wall of the mounting column, the water vapor crystallization powder can adhere to the extension, thereby enabling the recovery of lighter media and making the recovery efficiency of sodium sulfide crystals higher.

[0019] 2. By setting sliders and grooves, the movement direction of the moving frame can be limited to prevent the moving frame from rotating. By setting threaded rods, when the threaded rods rotate, they can drive the moving frame to move inside the exhaust pipe. By moving the moving frame, the position of the connecting rod at the top of the valve disc can be adjusted, thereby limiting the opening angle of the valve disc and thus adjusting the exhaust volume of the exhaust pipe.

[0033] The recycling mechanism includes a separator 6, a partition 9, a mounting plate 2, a mounting column 19, and an extension 21. The separator 6 is fixedly installed inside the recycling bin 1. The gap between the top of the separator 6 and the inner wall of the recycling bin 1 forms a first flow channel 7. The partition 9 is fixedly installed on the side wall of the separator 6. A second flow channel 8 is opened inside the separator 6 and is located at the top of the partition 9. The mounting plate 2 is installed inside the recycling bin 1. The mounting column 19 is fixedly installed at the bottom of the mounting plate 2 and is located between one side of the separator 6 and the inner wall of the recycling bin 1. The extension 21 is fixedly installed on the side wall of the mounting column 19.

[0034] Several mounting posts 19 and several extension pieces 21 are provided.

[0035] The top of the recycling bin 1 has an installation groove 12, the installation plate 2 is snapped into the installation groove 12, and the extension 21 is a brush.

[0036] In this embodiment, by setting up a partition frame 6, the water vapor generated during the evaporation process of the sodium sulfide waste alkali liquid inside the recovery box 1 can circulate inside the recovery box 1 through the first flow channel 7 and the second flow channel 8. This allows the water vapor to frequently come into contact with the mounting column 19 on the outside of the partition frame 6. The water vapor crystallization powder can be attached to the extension 21 on the side wall of the mounting column 19, thereby enabling the recovery of lighter media and making the recovery efficiency of sodium sulfide crystals higher. The bottom cover 11 makes it easy to remove the crystals inside the recovery box 1.

[0037] In one embodiment, a mounting member 14 is slidably connected to the side wall of the mounting post 19. The inner wall of the mounting member 14 has a mounting cavity 15. A spring 16 is fixedly installed on the inner wall of the mounting cavity 15. A snap-fit ​​member 17 is fixedly installed at one end of the spring 16. A snap-fit ​​groove 18 is opened on the side wall of the mounting post 19. The snap-fit ​​groove 18 fits with the snap-fit ​​member 17. A scraper 20 is fixedly installed at the bottom of the mounting member 14. The scraper 20 fits against the side wall of the mounting post 19.

[0038] In this example, the spring 16 can support the snap-fit ​​component 17, allowing the snap-fit ​​component 17 to snap into the snap-fit ​​groove 18, and the mounting component 14 to snap onto the side wall of the mounting post 19. At the same time, when the mounting component 14 is pushed hard, the snap-fit ​​component 17 can be disengaged from the snap-fit ​​groove 18, thereby driving the scraper 20 to scrape off the small particles adhering to the side wall of the mounting post 19, making collection convenient.

[0039] In one embodiment, an electric heating wire 10 is fixedly installed on the side wall of the partition 6, the electric heating wire 10 is located at the bottom of the partition 9, and an installation rod 5 is fixedly installed on the top of the mounting plate 2.

[0040] In this example, the electric heating wire 10 can be used to heat the sodium sulfide waste alkali liquid inside the partition rack 6 to evaporate the moisture, and the mounting rod 5 can be used to facilitate the removal of the mounting plate 2.

[0041] In one embodiment, an exhaust pipe 3 is fixedly installed on the top of the recycling bin 1. An adjustment mechanism is provided inside the exhaust pipe 3. The adjustment mechanism includes a bracket 22, a threaded rod 24, a movable frame 25, a connecting rod 26, a slider 27, a mounting shaft 29, a valve disc 30, and a limiting block 31. The bracket 22 is fixedly installed on the inner wall of the exhaust pipe 3. The threaded rod 24 is rotatably connected to the bracket 22.

The mounting shaft 29 is fixedly installed inside the exhaust pipe 3. The valve disc 30 is rotatably connected to the side wall of the mounting shaft 29. The limiting block 31 is fixedly installed on the inner wall of the exhaust pipe 3.

[0042] In this example, the moving direction of the movable frame 25 can be limited by setting the slider 27 and the groove 28 to prevent the movable frame 25 from rotating. When the threaded rod 24 rotates, it can drive the movable frame 25 to move inside the exhaust pipe 3. The position of the connecting rod 26 at the top of the valve disc 30 can be adjusted by moving the movable frame 25, thereby limiting the opening angle of the valve disc 30 and thus adjusting the exhaust volume of the exhaust pipe 3.

[0043] In one embodiment, a servo motor 23 is fixedly mounted on the top of the bracket 22, and a threaded rod 24 is fixedly mounted on the output end of the servo motor 23.

[0044] In this example, servo motor 23 can be used to control the rotation of threaded rod 24.
