[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The ionic liquid purification device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, the ionic liquid purification device provided in the embodiment of the present application includes a purification cylinder 1, and a heating separation mechanism 2 is arranged inside the purification cylinder 1. The heating separation mechanism 2 includes a liquid spray component 21, a heating component 22 and an inert gas protection component 23.

[0024] The liquid spray component 21 is arranged through the top of the purification cylinder 1, and the heating component 22 is arranged inside the purification cylinder 1. The heating component 22 includes a heating tower 221 and a reflux groove 223, wherein the heating tower 221 is a conical structure, the heating tower 221 is arranged in the purification cylinder 1, the reflux groove 223 is arranged at the bottom edge of the heating tower 221, and the liquid spray component 21 is arranged above the heating tower 221.

[0025] The inert gas protection assembly 23 includes an air jet ring 231 and an exhaust pipe 234 , wherein the air jet ring 231 is arranged outside the reflux groove 223 , and the exhaust pipe 234 is arranged through the top of the purification cylinder 1 .

[0026] The ionic liquid purification device of the present application uses a conical heating tower 221 to make the ionic liquid flow and diffuse evenly from top to bottom, so that the ionic liquid is heated more evenly. Inert gas is added through the inert gas protection component 23 to evaporate volatile impurities in the ionic liquid while reducing the mixing of impurities into the ionic liquid, so that the ionic liquid is purified more fully.

[0027] In one embodiment of the present application, Figure 2 As shown, a heating wire is arranged inside the heating tower 221, a heat insulating plate 225 is arranged at the bottom of the heating tower 221, and particle protrusions are evenly arranged on the outer surface of the heating tower 221. The spray assembly 21 sprays the ionic liquid downward from the top of the heating tower 221, and the ionic liquid flows downward evenly and dispersedly along the particle protrusions on the outer surface of the conical structure of the heating tower 221. Then, the heating wire inside the heating tower 221 is energized to heat the heating tower 221, thereby heating the ionic liquid and evaporating and separating the volatile substances in the ionic liquid.

[0028] In one embodiment of the present application, Figure 1 and Figure 2 and Figure 4 As shown, an air inlet pipe 233 is provided at the air inlet end of the jet ring 231, and an air nozzle 232 is provided on the inner side of the jet ring 231. The air nozzle 232 is inclined downward, and the outlet of the air nozzle 232 corresponds to the inside of the reflux groove 223. A reflux pipe 224 is provided at the bottom of the reflux groove 223, and a drainage needle 222 is provided at the bottom edge of the heating tower 221, which serves to drain the ionic liquid to the reflux groove 223.

[0029] Specifically, the inert gas enters the jet ring 231 through the air inlet pipe 233, and is sprayed obliquely downward into the reflux groove 223 along the jet nozzle 232. On the one hand, the inert gas drives the air in the purification cylinder 1 upward and is discharged from the exhaust pipe 234, so that the entire purification cylinder 1 is filled with inert gas protection; on the other hand, the jet nozzle 232 performs annular sweeping on the ionic liquid in the reflux groove 223, so that the ionic liquid is accelerated to flow from the reflux groove 223 to the reflux pipe 224 for discharge, thereby preventing the ionic liquid from accumulating.

[0030] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the purification cylinder 1 is a conical shell structure that can be split up and down, so that the inert gas can quickly fill the purification cylinder 1 and it is convenient to open the purification cylinder 1 later. Support legs 3 are provided at the bottom of the purification cylinder 1 to support the purification cylinder 1.

[0031] In one embodiment of the present application, Figure 3 and Figure 4 As shown, a centrifugal assembly 24 is also provided at the bottom of the purification cylinder 1. The centrifugal assembly 24 includes a centrifugal motor arranged below the heating tower 221. The power shaft 241 of the centrifugal motor is connected to the heating tower 221. A brush unit 242 is provided at the bottom of the purification cylinder 1. The brush unit 242 is electrically connected to the heating wire.

[0032] Specifically, the flow of the ionic liquid can be accelerated by energizing the centrifugal motor to drive the heating tower 221 to rotate. During the rotation of the heating tower 221, the internal heating wire is connected to the external power supply through the brush unit 242. At this time, the rotating heating tower 221 accelerates the downward flow of the ionic liquid and increases the efficiency of the ionic liquid impurity treatment.

[0033] In order to clearly explain the above embodiments, refer to Figure 1-4 The specific working principle of the ionic liquid purification device of the present application is as follows: First, the inert gas enters the jet ring 231 through the air inlet pipe 233, and the inert gas drives the air in the purification cylinder 1 upward and is discharged from the exhaust pipe 234, so that the entire purification cylinder 1 is filled with inert gas protection.

[0034] Subsequently, the spray component 21 sprays the ionic liquid downward from the top of the heating tower 221, and the ionic liquid evenly disperses and flows downward along the particle protrusions on the outer surface of the conical structure of the heating tower 221. Subsequently, the heating wire inside the heating tower 221 is energized to heat the heating tower 221, thereby heating the ionic liquid and evaporating and separating the volatile substances in the ionic liquid.

[0035] The ionic liquid flows downward along the heating tower 221 and enters the reflux groove 223 along the drainage needle 222. The air nozzle 232 performs an annular purge on the ionic liquid in the reflux groove 223, and finally the ionic liquid flows from the reflux groove 223 into the reflux pipe 224 for discharge.

[0036] In summary, the ionic liquid purification device of the embodiment of the present application uses a conical heating tower to make the ionic liquid flow and diffuse evenly from top to bottom, the heating is more evenly dispersed, and inert gas protection is added to reduce the mixing of impurities.
