[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A liquid-phase hydrogenation waste liquid purification device comprises four support frames 1, the interiors of the four support frames 1 are fixedly connected with a purification tank 2, the outer surfaces of the support frames 1 are fixedly connected with a feed pipe 3, a feeding pipe 4 and a discharge pipe 5, the feeding pipe 4 and the discharge pipe 5 are located on the same side and the feeding pipe 3 is located above the discharge pipe 5, the feeding pipe 4 is located on the other side and between the feeding pipe 3 and the discharge pipe 5, the outer surfaces of the feeding pipe 3, the feeding pipe 4 and the discharge pipe 5 are all fixedly installed with a valve 6, and further comprises:

[0029] A filtering component, which is located inside the purification tank 2 and is used to enhance the filtering effect of the liquid phase hydrogenation waste liquid;

[0030] The processing component is located inside the purification tank 2 and is used to purify the liquid-phase hydrogenation waste liquid in the purification tank 2. The valve 6 on the outer surface of the purification tank 2 is opened, and then the liquid-phase hydrogenation waste liquid is introduced into the purification tank 2 from the feed pipe 3. The valve 6 on the outer surface of the feeding pipe 4 is opened, and the purifying agent is poured into the feeding pipe 4 to be combined with the liquid-phase hydrogenation waste liquid after fine filtration. The valve 6 on the outer surface of the discharge pipe 5 is opened to allow the extracted liquid-phase hydrogenation waste liquid to flow out.

[0031] Furthermore, the filtering component includes a first filter screen 9, which is fixedly installed inside the purification tank 2 and is located below the feed pipe 3. When the liquid hydrogenation waste liquid enters the purification tank 2 and passes through the first filter screen 9, a first layer of filtering operation is performed on it.

[0032] Furthermore, a second filter screen 10 is fixedly installed inside the purification tank 2 . The second filter screen 10 is located below the first filter screen 9 and above the feeding pipe 4 . The liquid hydrogenation waste liquid after the first treatment flows to the second filter screen 10 again.

[0033] Furthermore, a plurality of annular equidistantly distributed columns 11 are fixedly connected inside the second filter screen 10 . The columns 11 are arranged in an umbrella shape and a plurality of equidistantly distributed rectangular grooves 13 are opened on the outer surface thereof. Fine filtration is performed through the plurality of rectangular grooves 13 on the columns 11 .

[0034] Furthermore, the processing component includes a power supply 7 and a thermal wire 12. The thermal wire 12 is fixedly connected to the inner wall of the purification tank 2, and the power supply 7 is fixedly installed on the outer surface of the purification tank 2. The power supply 7 is electrically connected to the thermal wire 12. The power supply 7 provides voltage to make electrons flow in the circuit to form current. The thermal wire 12, as a conductor, has a certain resistance. Resistance is the resistance of the conductor to the flow of current. When current flows through the thermal wire 12 with resistance, the electrons collide with the atoms in the thermal wire 12, converting kinetic energy into heat energy.

[0035] Furthermore, the heat conducting wire 12 is located below the second filter screen 10, and the heat energy generated by the heat conducting wire 12 will be conducted along the heat conducting wire 12 to increase its temperature, thereby heating the waste liquid to a certain temperature, so that the hydrogen, catalyst and organic impurities in the waste liquid can be fully dissolved and separated.

[0036] Furthermore, an observation port 8 is fixedly installed on the outer surface of the purification tank 2, and the purification process can be observed through the observation port 8.

[0037] Working principle: When the staff needs to use the liquid-phase hydrogenation waste liquid purification device, first open the valve 6 on the outer surface of the purification tank 2, and then introduce the liquid-phase hydrogenation waste liquid from the feed pipe 3 into the purification tank 2, so that the liquid-phase hydrogenation waste liquid enters the purification tank 2 and passes through the first filter screen 9 for the first layer of filtration to remove large particles and suspended matter. The liquid-phase hydrogenation waste liquid after the first treatment flows to the second filter screen 10 again, and is finely filtered through a plurality of rectangular grooves 13 on the column 11. The filtered liquid-phase hydrogenation waste liquid flows to the bottom of the second filter screen 10, and the valve 6 on the outer surface of the feeding pipe 4 is opened, and the purifying agent is poured into the feeding pipe 4 to combine with the finely filtered liquid-phase hydrogenation waste liquid, thereby chemically reacting with the impurities in the waste liquid. Generate easily separable compounds, and start power supply 7 at the same time. Power supply 7 provides voltage to make electrons flow in the circuit to form current. The heat conducting wire 12, as a conductor, has a certain resistance. Resistance is the barrier effect of the conductor on the flow of current. When current flows through the heat conducting wire 12 with resistance, the electrons collide with the atoms in the heat conducting wire 12, converting kinetic energy into thermal energy. The thermal energy generated by the heat conducting wire 12 will be conducted along the heat conducting wire 12 to increase its temperature, heat the waste liquid to a certain temperature, and fully dissolve and separate the hydrogen, catalyst and organic impurities in the waste liquid, thereby obtaining high-purity waste liquid. Open the valve 6 on the outer surface of the discharge pipe 5 to allow the liquid-phase hydrogenation waste liquid to flow out, and the purification process can be observed through the observation port 8.
