Description

Technical Field

[0001] This utility model relates to the field of waste ethanol solvent recovery technology, specifically a device for efficiently recovering waste ethanol solvent. Background Technology

[0002] Ethanol is a basic industrial raw material used extensively in various industries. As a basic industrial raw material, a large amount of waste ethanol is generated every day. If this waste ethanol is discharged directly, it will cause great pollution to the environment and also result in a huge waste. Therefore, it is necessary to recycle and reuse ethanol.

[0003] In the field of waste ethanol solvent recovery, the existing method of purifying and recovering waste ethanol is usually distillation. However, in actual use, although distillation can separate the components in the mixture, the separation effect of distillation may not be ideal for some mixtures with similar boiling points or forming azeotropes. In the process of ethanol evaporation and purification, other solvents will inevitably be purified along with the ethanol, resulting in poor ethanol purification effect. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that existing distillation methods can separate components in a mixture, but for mixtures with similar boiling points or forming azeotropes, the separation effect of distillation may not be ideal. Therefore, during the ethanol evaporation and purification process, other solvents will inevitably be purified along with the ethanol, resulting in poor ethanol purification.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for efficiently recovering waste ethanol solvent, characterized in that it comprises:

[0008] The recycling bin has a conveying pipe extending from its top and a PLC control terminal embedded above its front end. An inspection door is movably connected above the PLC control terminal at the front end of the recycling bin, and a sorting mechanism is installed inside the recycling bin.

[0009] The sorting mechanism includes a servo motor, which is fixedly installed on one side of the conveying pipe at the top of the recycling bin. A connecting frame is fixedly installed at the power output end of the servo motor, and a housing is fixedly installed at the axial end of the connecting frame. Filter packing is embedded inside the housing.

[0010] As a further embodiment of this utility model: a fixing cylinder is fixedly installed on the outer wall of the housing, and a locking plate is inserted into the outer wall of the fixing cylinder, and a permeable vaporization membrane is embedded inside the locking plate.

[0011] As a further improvement of this utility model: the bottom end of the recycling bin is provided with a flow hole, and a drainage pipe extends from the bottom end of the flow hole. A guide plate is fixedly installed on one side of the flow hole at the bottom end of the recycling bin.

[0012] As a further embodiment of this utility model: a discharge valve is fixedly installed at the bottom end of the fixed cylinder, and a heating vessel is fixedly installed at the bottom end of the recycling box.

[0013] As a further improvement of this utility model: a conveying shell is fixedly installed below the front end of the recycling bin, and a purification mechanism is provided inside the conveying shell.

[0014] As a further embodiment of this utility model: the purification mechanism includes a hydrophobic membrane, which is fixedly installed inside the heating vessel, and a condenser plate is embedded at the top of the heating vessel.

[0015] As a further improvement of this utility model: a through hole is provided on one side of the inside of the conveying shell corresponding to one end of the condenser plate, and an inclined plate is fixedly installed at the bottom of the inside of the conveying shell, and a control valve extends out from one side of the bottom of the conveying shell.

[0016] As a further improvement of this utility model: a filter screen is embedded above the front conveying shell of the recycling bin, and a cooling fan is embedded on the outer wall of the filter screen.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of filter packing, fixed cylinder, clamping plate and pervaporation membrane, realizes the filtration and purification of waste ethanol solvent mixture liquid through the dual combination of adsorption method and membrane filtration method. It avoids the direct heating distillation method, which causes other impurities with the same boiling point to vaporize along with it, resulting in other impurities in the ethanol and making it impossible to completely purify it.

[0019] 2. This utility model, through the design of a heating vessel, a hydrophobic membrane, a condenser plate, a filter screen, and a cooling fan, enables final distillation and purification. The hydrophobic membrane filters impurities with similar boiling points that cannot be completely vaporized, thereby further improving the purification effect of ethanol. Finally, the ethanol is liquefied and collected by the condenser plate, and the cooling fan dissipates heat from the condenser plate to avoid affecting the cooling effect.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 3This is the first embodiment of the present invention. This embodiment provides a device for efficiently recovering waste ethanol solvent, including: a recovery box 1, a conveying pipe 2 extending from the top of the recovery box 1, a PLC control terminal 3 embedded above the front end of the recovery box 1, an inspection door 4 movably connected above the PLC control terminal 3 at the front end of the recovery box 1, and a sorting mechanism 5 provided inside the recovery box 1.

[0031] The sorting mechanism 5 includes a servo motor 501, which is fixedly installed on one side of the conveying pipe 2 at the top of the recycling bin 1. A connecting frame 502 is fixedly installed at the power output end of the servo motor 501, and a housing 503 is fixedly installed at the axial end of the connecting frame 502. Filter packing 504 is embedded inside the housing 503.

[0032] Specifically, a fixing cylinder 505 is fixedly installed on the outer wall of the housing 503, and a locking plate 506 is inserted into the outer wall of the fixing cylinder 505. A pervaporation membrane 507 is embedded inside the locking plate 506.

[0033] Furthermore, by inserting the snap-fit ​​plate 506 into the reserved groove of the fixed cylinder 505, the pervaporation membrane 507 can block the fixed cylinder 505, and pressure is generated during rotation to allow ethanol and a mixture of the same size to escape.

[0034] Specifically, a flow hole 508 is provided at the bottom of the recycling box 1, and a drainage pipe 510 extends from the bottom of the flow hole 508. A guide plate 509 is fixedly installed on one side of the flow hole 508 at the bottom of the recycling box 1.

[0035] Furthermore, the guide plate 509 and the flow hole 508 facilitate the guidance of the escaping liquid into the drain pipe 510 and downwards.

[0036] Specifically, a discharge valve 6 is fixedly installed at the bottom of the fixed cylinder 505, and a heating vessel 7 is fixedly installed at the bottom of the recycling box 1.

[0037] Furthermore, the heating vessel 7 can further heat and purify the liquid. The heating vessel 7 is equipped with an electrically controlled valve and is connected to the drain water for easy discharge. After purification, the water or larger mixtures filtered out can be discharged by opening and closing the manual discharge valve 6.

[0038] In use, waste ethanol is introduced into the housing 503 of the recovery tank 1 through the conveying pipe 2. It undergoes preliminary filtration through the filter media 504, such as activated carbon. Simultaneously, under the control of the PLC control terminal 3, the servo motor 501 and the connecting frame 502 drive the housing 503, thereby rotating the fixed cylinder 505. The fixed cylinder 505 is slidably connected to the locking plate 506 and fixed with bolts, which facilitates the disassembly and assembly of the pervaporation membrane 507. It can be cleaned or maintained regularly in the future. During the rotation of the fixed cylinder 505, the waste ethanol undergoes centrifugal motion, which causes the ethanol and the mixed solution of the same size to be thrown out. The mixture is guided by the guide plate 509 into the flow hole 508, and then enters the drainage pipe 510 to be transported to the heating kettle 7 for purification. With the help of the manual discharge valve 6, the maintenance door 4 can be opened to start the discharge valve 6 after the recovery is completed, allowing the other mixed solutions filtered out inside to directly enter the heating kettle 7 and be discharged from the drain.

[0039] In summary, the bottom of the housing 503 is provided with a small through hole to facilitate the carrying of the filter packing 504 and allow waste ethanol to flow through the filter packing 504 for adsorption. It is then filtered again in conjunction with the pervaporation membrane 507. With double-layer filtration and adsorption, it can avoid distillation and purification, and prevent other liquids from being purified together due to temperature, which would affect the purification effect. At the same time, the inspection door 4 facilitates the regular maintenance or replacement of the filter packing 504 and the pervaporation membrane 507.

[0040] Example 2

[0041] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design of a device for efficiently recovering waste ethanol solvent.

[0042] Specifically, a conveying shell 8 is fixedly installed at the lower front end of the recycling bin 1, and a purification mechanism 9 is installed inside the conveying shell 8.

[0043] Furthermore, the purified ethanol is finally collected and discharged through the conveying shell 8.

[0044] Specifically, the purification mechanism 9 includes a hydrophobic membrane 901, which is fixedly installed inside the heating vessel 7, and a condenser plate 902 is embedded at the top of the heating vessel 7.

[0045] Furthermore, the ethanol heated by the heating vessel 7 vaporizes, and the gas can be filtered through the hydrophobic membrane 901 and adsorbed on the condenser plate 902. It can then be filtered and purified again through the hydrophobic membrane 901 to improve the ethanol purification effect.

[0046] Specifically, a through hole 903 is provided on one side of the inside of the conveying shell 8 corresponding to one end of the condenser plate 902, an inclined plate 904 is fixedly installed at the bottom of the inside of the conveying shell 8, and a control valve 905 extends out from one side of the bottom of the conveying shell 8.

[0047] Furthermore, the inclined condenser plate 902 facilitates the liquefaction of adsorbed ethanol gas and guides its flow into the through hole 903, where it drips into the inside of the conveying shell 8. The flow is then guided by the inclined plate 904 and finally discharged uniformly through the opening and closing of the control valve 905.

[0048] Specifically, a filter screen 906 is embedded above the front conveying shell 8 of the recycling bin 1, and a cooling fan 907 is embedded on the outer wall of the filter screen 906.

[0049] Furthermore, the recycling bin 1 is equipped with a ventilation channel, inside which is embedded a condenser plate 902 heat dissipation section. The air circulation is improved by a filter screen 906 and a cooling fan 907 at one end, which increases the heat dissipation effect and avoids dust adsorption, thus improving the heat dissipation efficiency of the lead wire.

[0050] In use, the mixed solution containing ethanol is first guided into the heating vessel 7 through the guide tube 510 for reheating, distillation and purification. The boiling point matches that of ethanol, so it becomes a gas. Water vapor, which contains other impurities, is filtered again through the hydrophobic membrane 901. Finally, the ethanol gas is adsorbed on the condenser plate 902 and liquefied. It is then guided through the through hole 903 and drips into the conveying shell 8. It is then guided and collected by the inclined plate 904 and finally discharged under the control of the control valve 905. The recovery box 1 is equipped with a ventilation channel for the hot end of the condenser plate 902, and the heat dissipation effect is improved by the filter screen 906 and the cooling fan 907.

[0051] In summary, after separating other impurities of different sizes, the other impurities of the same size are distilled by temperature, which achieves classification, filtration and purification, thereby improving the purity of ethanol. After being liquefied by the condenser plate 902, it is collected and discharged by the conveying shell 8. With the cooperation of the filter screen 906 and the cooling fan 907, the hot end of the condenser plate 902 is prevented from being overloaded, which has a certain heat dissipation effect.
