DETAILED DESCRIPTION

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] The drawings will be described below in conjunction with the embodiments of the present application. Figures 1-4 The present application will be further described in detail. The present application is an electrophoresis separation reaction device for humic acid raw materials. The reaction device comprises a reaction shell 16. The inside of the reaction shell 16 is divided into a cathode chamber 1 and an anode chamber 2 by a diaphragm 6. At least a cathode part is arranged in the cathode chamber 1. At least an anode part and a sediment material flat pushing part arranged at the bottom of the anode chamber 2 are arranged in the anode chamber 2. The present application creates the cathode chamber 1 and the anode chamber 2 by the diaphragm 6 and the electrode. An alkaline environment is created in the cathode chamber 1 by an external electric field for activating humic acid. At the same time, humic acid anions migrate to the anode. The insoluble impurities are removed through the diaphragm 6. Similarly, an acid environment is created in the anode chamber 2 by an external electric field. The humic acid anions become humic acid again under the acid environment in the anode chamber 2 and flocculate and precipitate. The flocculation and precipitation are sent out through the sediment material flat pushing part arranged at the bottom of the anode chamber 2 and used as humic acid products. The soluble impurities are excluded. Thus, the high separation of humic acid is realized. The above process has the characteristics of not using dangerous chemicals, not producing harmful gas, reducing the pollution to the environment and avoiding the threat to the personal safety of the on-site operators. The continuous production and high separation degree are achieved.

[0024] Further, the cathode part is arranged at the corresponding position of the diaphragm 6. The top of the cathode chamber 1 is provided with a feeding port 9 and a cathode chamber exhaust port 13. The bottom of the cathode chamber 1 is provided with a discharge port 11. The present application enters the humic acid raw material through the feeding port 9. The cathode chamber 1 reduces hydrogen ions to hydrogen gas through the cathode part, promotes the ionization of humic acid to release humic acid anions, and discharges the hydrogen gas produced in the above process through the cathode chamber exhaust port 13. The waste liquid in the above reaction process is discharged through the discharge port 11.

[0025] Further, the cathode part comprises a negative electrode sheet 3 connected with a power supply.

[0026] Further, the cathode chamber 1 is further provided with a full mixing flow part. The full mixing flow part comprises a plurality of stirring units uniformly arranged in the cathode chamber 1. The full mixing flow part comprises a plurality of stirring units uniformly arranged in the cathode chamber 1. The stirring unit comprises a stirring motor 5 arranged at the top of the reaction shell 16. The main shaft of the stirring motor 5 is connected with a stirring shaft provided with stirring blades 17 in the cathode chamber 1. The full mixing flow part can be arranged to backmix the material and promote the reaction.

[0027] Further, the top of the cathode chamber 1 is also provided with a temperature sensor 15. By providing the temperature sensor 15, the temperature can be monitored in real time to ensure stable operation of the entire device.

[0028] Further, the anode part is arranged at a position corresponding to the diaphragm 6, the top of the anode chamber 2 is provided with a liquid inlet 10 and an anode chamber exhaust port 14, the middle of the anode chamber 2 is provided with a liquid outlet 12, and the bottom of the anode chamber 2 is provided with a humic acid product outlet 8 connected to the end of the sediment material pushing part. The anode chamber 2 oxidizes hydroxyl ions into oxygen and water through the anode part, promotes the ionization of water into hydrogen ions, and at the same time, the hydrogen ions combine with humic acid anions driven by the electric field to produce humic acid precipitation, thereby removing soluble impurities; the flocculation and precipitation produced during the reaction is the humic acid product, which can be pushed out of the humic acid product outlet 8 by the sediment material pushing part.

[0029] Further, the sediment material pushing part is a spiral discharge machine 7.

[0030] Further, the anode part includes a positive plate 4 connected to a power source.

[0031] The specific working process of the utility model is as follows: humic acid raw material slurry enters cathode chamber 1 from feed inlet 9, the material is continuously stirred under the joint action of stirring motor 5 and stirring blade 17 in cathode chamber 1, water is injected from liquid inlet 10 to keep the liquid level of anode chamber 2, negative plate 3 is connected to the negative pole of power supply, positive plate 4 is connected to the positive pole of power supply, it is suggested that a small amount of strong alkali is added in cathode chamber 1 for the first time to initiate the reaction to improve the efficiency (as the standard of a small amount of humic acid being dissolved), it is suggested that the voltage is approximately 10V / cm voltage difference, because the molecular weight of humic acid in raw materials is different, the selected voltage is also different, the voltage can be increased for large molecular weight, and vice versa for small molecular weight; hydrogen ions are reduced and converted into hydrogen gas on negative plate 3, and the hydrogen gas is discharged from cathode chamber exhaust port 13, this process will promote the ionization of humic acid molecules into hydrogen ions, thereby releasing humic acid anions, and under the action of electric field, humic acid anions are pushed to move to the positive pole, and pass through diaphragm 6 (according to relevant standards, ceramic filter membrane with aperture < 50 μm is selected as diaphragm, so that insoluble substances cannot penetrate), hydroxyl ions are oxidized into oxygen and water on positive plate 4, and the gas is discharged through anode chamber exhaust port 14, this process will make the hydrogen ions ionized by water accumulate, and at the same time, combine with the migrated humic acid anions to become humic acid, and the humic acid precipitates in an acidic environment, and is discharged from humic acid product outlet 8 by bottom screw discharge machine 7. The discharge is a swollen humic acid mud product with solid content of about 2-3%, the solid content of raw materials is different for different activities, the higher the activity, the lower the solid content, and direct drying can obtain humic acid solid with content of more than 95%; further, the temperature is monitored by temperature sensor 15, and it is suggested that the temperature is maintained below the boiling point to avoid potential danger and energy waste; it is noted that the material concentration in cathode chamber 1 can be controlled by discharging through discharge port 11 when adjusting the raw material slurry concentration, the pH value in anode chamber 2 can be controlled at 3-4, and the liquid can be discharged through liquid discharge port 12 and diluted by injecting water from liquid inlet 10. Because raw materials often contain ammonium ions and trace nitrate, a small amount of ammonia gas will be produced in cathode chamber 1 in addition to hydrogen gas, ammonia gas is easy to absorb and used in other fertilizers, and hydrogen gas can be recycled for coal liquefaction or ammonia synthesis. In addition to oxygen in anode chamber 2, carbon dioxide from carbonate decomposition will also be produced, and trace hypochlorous acid produced by anode will also oxidize humic acid to produce carbon dioxide, which can be directly discharged or recycled; the acid and alkali produced in the above process can be directly used in the traditional humic acid alkali dissolution and acid precipitation purification process; the above process has the characteristics of not using dangerous chemicals, not producing harmful gas, reducing environmental pollution and avoiding threats to the personal safety of on-site operators, and at the same time, the purpose of continuous industrial production can be realized.
