Description

Technical Field

[0001] The present invention relates to the technical field of isopentenol production, and specifically to a method for collecting residual liquid in isopentenol production. Background Art

[0002] Isoamyl alcohol is an organic compound with the chemical formula C5H12O. It belongs to the alcohol compound category and is a colorless transparent liquid with a strong aroma. It exists in many fruits and teas in nature and is commonly used as a flavor enhancer in food and beverage flavors. Industrially, isopentenol is mainly used to prepare organic compounds such as esters and ketones. It is a raw material for many pesticides, pharmaceuticals, and flavors. In addition, it can also be used as a solvent for dyes, oils, and various resins, especially nitrocellulose. Moreover, isopentenol is widely used in the refining of petrochemical products.

[0003] However, during the production of isopentenol, some chemical residual liquids are generated. Usually, manual labor is required to fill the residual liquid into a collection bottle for collection. However, long-term contact with the skin or eyes during the collection process is irritating, and inhalation or ingestion is also harmful to the human body. These residual liquids need to be properly collected and treated. Therefore, a method for collecting residual liquid in isopentenol production is provided. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for collecting residual liquid in isopentenol production, which solves the problem that long-term contact with the skin or eyes during the manual collection of isopentenol residual liquid is irritating, and inhalation or ingestion is also harmful to the human body.

[0007] b. Separating solid and liquid: The residual liquid may contain solid particles and needs to be separated. The solid particles can be separated by methods such as filtration or centrifugation to obtain a liquid phase containing a solution;

[0008] c. Separating organic substances: If the residual liquid contains other organic substances, such as organic solvents or other organic materials, the separation of organic substances needs to be carried out, which can be achieved by distillation, extraction, or other appropriate separation techniques;

[0009] d. Recovery of the target substance: In the liquid phase, the target substance (such as isoprenol) can be recovered by methods such as distillation, extraction, crystallization, etc. According to the characteristics of the target substance and the solvent selectivity, select a suitable recovery method for operation;

[0010] e. Treatment of waste liquid: There may be other components in the residual liquid after recovery, and waste liquid treatment is required.

[0037] Combined Figure 1 with Figure 2 , an embodiment provided by the present invention includes the following steps:

[0038] a. Collecting residual liquid: During the production process of isopentenol, the generated residual liquid needs to be collected. Usually, the residual liquid will flow out through the outlet of the pipeline or equipment into the collection container or collection tank;

[0039] b. Separating solid and liquid: The residual liquid may contain solid particles and needs to be separated. The solid particles can be separated by methods such as filtration or centrifugation to obtain a liquid phase containing the solution;

[0040] c. Separating organic substances: If the residual liquid contains other organic substances, such as organic solvents or other organic materials, the separation of organic substances needs to be carried out, which can be achieved by distillation, extraction or other appropriate separation techniques;

[0041] d. Recovering the target substance: In the liquid phase, the target substance (such as isopentenol) can be recovered by methods such as distillation, extraction, crystallization, etc. According to the characteristics of the target substance and the solvent selectivity, a suitable recovery method is selected for operation;

[0042] e. Treatment of waste liquid: There may be other components in the residual liquid after recycling, and waste liquid treatment is required. Appropriate methods such as neutralization, oxidation, precipitation or other treatment technologies can be used to reduce the impact on the environment;

[0043] The collection container used in step 1 includes a collection bottle 1. A threaded bottle mouth 2 is fixedly connected to the top of the collection bottle 1. A threaded cap 6 is threadedly connected to the top of the threaded bottle mouth 2. During use, the threaded cap 6 is screwed onto the threaded bottle mouth 2. A liquid inlet pipe 10 passes through and is fixedly connected to the middle of the threaded cap 6. A first fastener 11 is fixedly connected to the bottom of the liquid inlet pipe 10. A valve 12 passes through and is fixedly connected to the bottom of the first fastener 11. An electronic switch 13 is arranged in the middle of the front side of the valve 12 to control the opening and closing of the valve 12. A water level gauge 7 passes through and is fixedly connected to the upper right part of the top of the threaded cap 6. A water level gauge 8 is arranged at the top of the water level gauge 7. The rising height of the isopentenol residual liquid in the collection bottle 1 can be viewed through the water level gauge 7 and the water level gauge 8. An alarm 9 is arranged in the middle of the rear side of the water level gauge 8. When the residual liquid rises to a certain height, it will be transmitted to the alarm 9 through the electrical connection between the water level gauge 8 and the alarm 9, causing the alarm 9 to sound. A control panel 20 is arranged behind the water level gauge 8 and the control panel 20 is fixedly connected to the threaded cap 6. When the operator hears the alarm, through the electrical connection between the control panel 20 and the electronic switch 13, the electronic switch 13 is controlled to close the valve 12 to prevent the isopentenol residual liquid from overflowing during transportation. A ring 3 is rotatably connected to the bottom outer wall of the threaded bottle mouth 2. A connecting belt 4 is fixedly connected to the right side of the outer wall of the ring 3. The other end of the connecting belt 4 is fixedly connected to a threaded sealing cap 5 and the threaded sealing cap 5 cooperates with the collection bottle 1. When it is necessary to replace the collection bottle 1, the threaded cap 6 is opened and taken out, and then the threaded sealing cap 5 is screwed onto the threaded bottle mouth 2 to seal the threaded bottle mouth 2.

[0044] Combined with 3 and Figure 4 At the upper left part of the top of the threaded cap 6, an exhaust pipe 14 passes through and is fixedly connected. The top end of the exhaust pipe 14 is threadedly connected to a second fastener 15. The other end of the second fastener 15 is threadedly connected to a filter cartridge 16. Filter meshes 17 are arranged at both the front and rear ends inside the filter cartridge 16. Activated carbon 18 is arranged in the middle inside the filter cartridge 16. A sponge layer 19 is arranged behind the front-end filter mesh 17. When gas is generated inside the collection bottle 1 with isopentenol residual liquid, the gas will be transmitted to the filter cartridge 16 through the exhaust pipe 14 and the second fastener 15, and after passing through the filter mesh 17, the activated carbon 18 and the sponge layer 19, the harmful gas will be filtered and adsorbed.

[0045] Working principle: When collecting the residual liquid, screw the threaded cap 6 onto the threaded bottle mouth 2, which will fix the water level gauge 7, the first fastener 11, the valve 12, the electronic switch 13, and the exhaust pipe 14 connected to the threaded cap 6 and insert them into the collection bottle 1. The isopentenol residual liquid is transported into the collection bottle 1 through the liquid inlet pipe 10 for collection. When the liquid inlet pipe 10 transports the isopentenol residual liquid, it will pass through the first fastener 11 and the valve 12. When gas is generated inside the collection bottle 1 due to the isopentenol residual liquid, the gas will be transmitted through the exhaust pipe 14 and the second fastener 15 to the filter cartridge 16, and harmful gases will be adsorbed through the filter screen 17, activated carbon 18, and sponge layer 19. When the isopentenol residual liquid is transported into the collection bottle 1, the rising height of the isopentenol residual liquid in the collection bottle 1 can be checked through the water level gauge 7 and the water level indicator 8. When the residual liquid rises to a certain height, it will be transmitted to the alarm 9 through the electrical connection between the water level indicator 8 and the alarm 9, causing the alarm 9 to sound. When the operator hears the alarm, through the electrical connection between the control panel 20 and the electronic switch 13, the electronic switch 13 is controlled to close the valve 12 to prevent the possibility of overflow of the isopentenol residual liquid during transportation. When the alarm 9 sounds, it indicates that the collection bottle 1 needs to be replaced. First, open and remove the threaded cap 6, and then screw the threaded seal 5 onto the threaded bottle mouth 2 to seal the threaded bottle mouth 2.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
