The waste liquid test tank 1 is connected with the reaction chamber 3 through the switching device 2. Before recycling and processing, the narcotic drugs need to be weighed and quantified, and then subjected to harmless treatment through the waste liquid treatment component 5.

[0039] Preferably, the narcotic drug processing sequence is equipped with an electric control rail 30 , and a spectrum detector 4 is installed on the electric control rail 30 .

[0040] Preferably, the waste liquid test tanks 1 are arranged into several groups, and each group of waste liquid test tanks 1 is made of transparent glass, so that the spectrometer 4 can detect the narcotic drugs therein conveniently.

[0041] Preferably, the data recorded in the present invention are all recorded through the existing patent: CN202410319027.0 - A system and method for controlling the recovery and management of anesthetic waste liquid.

[0042] The working principle and beneficial effects of the above scheme are as follows: different types of narcotic liquids are respectively put into the waste liquid test tank 1, and then weighed and recorded. First, the spectrometer detector 4 is controlled by the electric control rail 30 to detect and qualitatively detect the narcotic liquid in each waste liquid test tank 1, so as to determine that the liquid in the waste liquid test tank 1 is indeed narcotic liquid, and then the data is recorded and saved. Then, the narcotic liquid in several groups of waste liquid test tanks 1 is transported to the reaction chamber 3 in turn through the switching device 2. In order to improve the harmless treatment effect of the narcotic liquid, a catalyst needs to be added to the reaction chamber 3, and the type of catalyst needs to be set separately according to the pharmacology of the narcotic liquid, for example: hydrogen peroxide, potassium permanganate, etc. Then, the narcotic liquid after the reaction in the reaction chamber 3 is discharged into the waste liquid treatment component 5 for further treatment, and during the discharge process, it is necessary to perform quantitative weighing through the waste liquid weighing platform 4 to ensure the treatment effect.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 2 The switching device 2 includes: a first support ring 6 and a second support ring 14, the first support ring 6 and the second support ring 14 are connected by two groups of support rods 12, the first support ring 6 has a first drive disc 9 fixedly installed at the center, and the second support ring 14 has a second drive disc 15 rotatably installed at the center.

[0045] Preferably, a plurality of through holes 10 are formed on the first driving disc 9 , and the plurality of waste liquid connecting pipes 8 correspond one by one to the plurality of through holes 10 on the first driving disc 9 , and each group of waste liquid connecting pipes 8 is connected to a group of waste liquid test tanks 1 .

[0046] Preferably, the drive motor 7 is installed on the first drive disc 9 near the middle of the waste liquid test tank body 1, and the drive motor 7 moves through the first drive disc 9 and is fixedly connected to the drive rod 13, the end of the drive rod 13 away from the drive motor 7 is fixedly connected to the second drive disc 15, two groups of mounting brackets 16 are fixedly connected to the second drive disc 15, the mounting ring 18 is installed between the two groups of mounting brackets 16 through the fixing rod 29, one end of the guide tube 17 is connected to the mounting ring 18, and the other end of the guide tube 17 passes through the second drive disc 15 to be connected to the connecting pipe 11, and the reaction chamber 3 is connected to the mounting ring 18 through the docking piece 19.

[0047] Preferably, a peristaltic pump is also installed on the waste liquid connecting pipe 8.

[0048] The working principle and beneficial effects of the above scheme are as follows: when in use, firstly, the flow guide tube 17 is connected to the reaction chamber 3 through the docking piece 19, and then several groups of waste liquid connecting tubes 8 are respectively connected to different waste liquid test tank bodies 1. After the qualitative evaluation of the narcotic liquid is completed, the narcotic liquid in one group of waste liquid test tank bodies 1 is extracted by a peristaltic pump and enters the reaction chamber 3 along the connecting tube 11, the flow guide tube 17 and the docking piece 19 for treatment, and then the connecting tube 11 is disconnected from the through hole 10 corresponding to the group of waste liquid connecting tubes 8, and the driving motor 7 is started to drive the second driving disc 15 to rotate through the driving rod 13, so that the connecting tube 11 moves to the through hole 10 corresponding to the next waste liquid connecting tube 8 for docking, and the peristaltic pump is started to continue extraction. By repeating the above operation, different narcotic liquids in the waste liquid test tank body 1 can be alternately extracted into the reaction chamber 3 for reaction, which greatly improves the processing efficiency.

[0049] Among them, a group of waste liquid connecting pipes 8 need to be filled with clean water. Before each switching, the connecting hose 11 needs to be connected with the waste liquid connecting pipe 8 filled with clean water, and then the connecting pipe 11, the guide pipe 17, the docking piece 19 and the reaction chamber 3 need to be cleaned to prevent cross contamination.

[0050] Example 3

[0051] Based on any one of Examples 1-2, please refer to Figure 3 The waste liquid treatment assembly 5 includes: a treatment tank body 20, and a filter screen 21, a guide plate 22 and a support frame 26 are fixedly installed on the inner wall of the treatment tank body 20 from top to bottom.

[0052] Preferably, the guide plate 22 and the filter screen 21 are used to isolate the top of the processing tank body 20 to form a liquid storage chamber 1 27 , and the support frame 26 and the bottom inner wall of the processing tank body 20 are isolated to form a liquid storage chamber 28 .

[0053] Preferably, a solenoid valve 23 is installed on the guide plate 22 , and the ultraviolet lamp 25 is installed at the top center of the support frame 26 .

[0054] Preferably, the spiral tube 24 is disposed around the outer wall of the ultraviolet lamp 25 , and one end of the spiral tube 24 is connected to the liquid storage chamber 1 27 , and the other end of the spiral tube 24 is connected to the liquid storage chamber 28 .

[0055] Preferably, the processing tank 20 is made of transparent glass.

[0056] Preferably, the spiral tube 24 is arranged around the outer wall of the ultraviolet lamp 16, and one end of the spiral tube 24 is connected to the liquid storage chamber 18, and the other end of the spiral tube 24 is connected to the liquid storage chamber 2 19. The spiral tube 24 is made of transparent glass, wherein the number of ultraviolet lamps 16 is set according to actual needs, and can be in the form of a group of spiral tubes 24 wrapped around the outer wall of each ultraviolet lamp 16, or can be in the form of multiple groups of ultraviolet lamps 16 wrapped around four groups of parallel spiral tubes 24.

[0057] The ultraviolet light emitted by the ultraviolet lamp 16 can render the narcotic liquid harmless. The specific effect of the ultraviolet light on the benzene ring structure mainly involves the following specific chemical processes:

[0058] Electronic excitation: UV light can excite the π electrons in the benzene ring, causing them to transition from the ground state molecular orbital (HOMO) to the excited state molecular orbital (LUMO), resulting in changes in the molecular orbital of the benzene ring, thereby affecting its conductivity and chemical properties37.

[0059] Photochemical reaction: Benzene ring may undergo photochemical reactions under the action of ultraviolet light, such as photolysis and photoisomerization. These reactions may cause changes in the structure of the benzene ring, such as ring-opening reaction of the benzene ring or the formation of active intermediates such as free radicals37.

[0060] Changes in molecular orbitals: In 4,4′-acetamidoazobenzene molecules that are ortho-tetrasubstituted by halogen atoms (such as F, Cl, Br, I), the plane of the benzene ring is distorted due to the steric hindrance and electrostatic repulsion of the substituents. This structural change is accompanied by changes in the molecular orbitals, which in turn affect its optical properties37.

[0061] Photoisomerization: Azobenzene and its derivatives can undergo cis-trans isomerization under UV light irradiation. This isomerization process involves the torsion of the C–N=N–C dihedral angle of the azo group connected to the benzene ring, resulting in the transformation of the molecule from a trans structure to a cis structure or vice versa37.

[0062] Energy transfer and electron transfer: UV light may also induce energy transfer or electron transfer processes, with the benzene ring acting as a donor or acceptor in the transfer of energy or electrons, which may affect the stability and reactivity of the benzene ring37.

[0063] Formation of free radicals: The action of ultraviolet light may cause the bonds between carbon atoms and hydrogen atoms on the benzene ring to break, forming free radicals, which can further participate in various chemical reactions, leading to the destruction or change of the benzene ring structure32.

[0064] Interactions in surfactant systems: In surfactant systems containing benzene ring structures, UV light may affect specific non-covalent interactions promoted by the benzene ring, such as cation-π and π-π interactions, thereby changing the aggregate structure and colloidal properties36.

[0065] These chemical processes illustrate the potential effects of UV light on the benzene ring structure, including changes in electronic states, distortions in the molecular structure, isomerization reactions, and possible free radical generation.

[0066] In summary, the anesthetic liquid can be purified after being irradiated with ultraviolet light.

[0067] The working principle and beneficial effects of the above scheme:

[0068] The treated narcotic liquid in the reaction chamber 3 is discharged into the treatment tank 20, flows through the filter screen 21 for filtration, and then accumulates on the guide plate 22. The spectrum detector 4 is controlled by the electric control rail 30 to detect and characterize the accumulated narcotic liquid on the guide plate 22, so as to ensure that the liquid therein is the treated narcotic liquid and then record and save the data. Then the solenoid valve 23 is controlled to open, and the narcotic liquid flows through the spiral tube 24. Under the irradiation of the ultraviolet lamp 25, the narcotic liquid undergoes a photochemical reaction. At this time, the most critical benzene ring in the narcotic liquid may undergo a photochemical reaction under the action of ultraviolet light, such as photolysis, photoisomerization, etc. These reactions will cause changes in the structure of the benzene ring, so that the narcotic liquid flowing into the second liquid storage chamber 28 is harmlessly treated.

[0069] When the liquid storage chamber 28 is full and needs to be discharged, the spectrum detector 4 needs to be controlled by the electric control rail 30 to move and detect the accumulated narcotic liquid in the liquid storage chamber 28 to determine whether it has been completely rendered harmless before it can be discharged.

[0070] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
