Description

Technical Field

[0001] The utility model relates to a device for producing aluminum oxide, in particular to a coupling device for ultrasonically enhancing the degradation of organic impurities in a sodium aluminate solution. Background Art

[0002] In the production of alumina, the organic carbon in the sodium aluminate solution mainly comes from the ore, and a small amount comes from various organic additives added during the production process. The organic matter content in imported bauxite is high and the composition is complex. When the imported bauxite is dissolved, 70-80% of the organic carbon will be converted into low molecular weight compounds such as oxalate and acetate, as well as high molecular weight humate, which seriously threatens the Bayer process of producing alumina; increases the difficulty of key operating processes such as dissolution, sedimentation, decomposition and evaporation; causes a significant increase in power consumption and alkali consumption; significantly reduces the seed decomposition rate; and causes product quality problems such as fine particle size of alumina products, excessive sodium oxide content and color of aluminum hydroxide.

[0003] Alumina manufacturers that use bauxite with high organic carbon content as raw materials have conducted a lot of research on this. The main methods include: calcination, oxidation, adsorption, ion exchange, crystallization, etc. Among the many methods, chemical oxidation is the most promising method for removing organic matter in the alumina production process because of its advantages such as simple process, clean and environmental protection, and easy industrialization. However, at present, various oxidants have problems such as low mass transfer efficiency, short contact time, and low oxidation efficiency in the process of oxidizing organic impurities. Therefore, the development of efficient and low-cost comprehensive organic impurity removal technology has scientific value and practical significance for the rational use of foreign ores and the improvement of the competitiveness of domestic alumina production. Utility Model Content

[0007] The jet device comprises a jet device motor 2 , a centrifugal pump 3 and a jet pipeline which are connected in sequence.

[0008] The jet pipeline includes a jet liquid / gas inlet pipe 1, a jet vacuum pump 4 and a jet tail pipe 5 which are connected in sequence. The jet liquid / gas inlet pipe 1 is externally connected to a liquid / gas storage tank. The jet tail pipe 5 passes through the vertical through hole at the top center of the ultrasonic reaction chamber 13 and is vertically inserted downward to the bottom of the ultrasonic reaction chamber 13. The inner diameter of the jet tail pipe 5 is much smaller than the inner diameter of the jet liquid / gas inlet pipe 1.

[0009] Preferably, the inner diameter of the jet tail pipe 5 is 1 / 5 to 1 / 15 of the inner diameter of the jet liquid / gas inlet pipe 1 .

[0010] Preferably, the impurity liquid outflow outlet 17 is provided with an electromagnetic valve 20 .

[0011] Preferably, the impurity liquid outflow outlet 17 is externally connected to the filtering device 15 , and a filtrate outlet 18 is provided at the bottom of the filtering device 15 .

[0012] Preferably, a plurality of filter plates 14 are arranged in the filter device 15 along the liquid flow direction.

[0013] The ultrasonic generator includes an ultrasonic cavity 8, a transducer 9 and an ultrasonic probe 6. A thermal insulation layer 10 is arranged at the bottom end of an ultrasonic reaction chamber 13. The ultrasonic cavity 8 is arranged at the lower end of the thermal insulation layer 10.

A horn 7 is arranged at the bottom end of the ultrasonic cavity 8. The transducer 9 is fixedly arranged at the bottom end of the horn 7. A plurality of magnetrons 12 connected in series are evenly arranged on the side wall of the ultrasonic cavity 8. An exhaust port 11 is opened on the side wall of the ultrasonic cavity 8. The exhaust port 11 passes through the gap between adjacent magnetrons 12.

[0014] The ultrasonic enhanced degradation coupling device for organic impurities in sodium aluminate solution also includes a control panel 22 , and the ultrasonic generator, the temperature sensor and the ultrasonic reaction chamber 13 are all connected to the control panel 22 by signals.

[0015] Preferably, the control panel 22 is provided with a temperature display instrument 23, an ultrasonic system control button and a jet system control button, the ultrasonic system control button is connected to the ultrasonic device, and the jet system control button is connected to the jet device.

[0016] More preferably, the ultrasound system control buttons include an ultrasound power button 26, a power display meter 24, a power adjustment knob 28 and an ultrasound operation warning light 27; the jet system control buttons include a flow display meter 25, a power button 30, a jet operation warning light 29, and a jet speed adjustment button 31.

[0018] Ultrasound is an elastic mechanical wave with a frequency higher than 20kHz. It can cause a series of physical and chemical changes in the solution based on the cavitation effect. During the implosion and annihilation of cavitation bubbles, local high temperatures of more than 5000K can be generated, about 5×10 7 Pa local high pressure, strong shock waves and microjets with speeds up to 400 km / h, and instantaneous temperature gradients up to 10 9 K / s, and at the same time caused turbulence effect, perturbation effect, interface effect, and energy gathering effect; the utility model utilizes ultrasound to strengthen the mass transfer process of the oxidant, increases the contact area between the oxidant and the organic matter, and realizes rapid and efficient degradation of the organic matter.

[0019] When the oxidant liquid flows into the jet tube at a certain flow rate, it is subjected to high-speed impact, cavitation, strong shear crushing, high-frequency oscillation, puffing and vortex effects, and is crushed into extremely small droplets, thereby increasing the contact area between the oxidant and the organic matter; in addition, the oxidant liquid flow flowing out of the jet system has strong hydraulic shear force, tension and shear stress, which can also destroy the carbon bonds on the main chain of macromolecular organic matter, thereby achieving efficient degradation of organic matter in the sodium aluminate solution.

[0020] In summary, by coupling the ultrasound and jet combined system, a uniform and efficient acoustic cavitation process can be achieved by regulating the sound field and bubble field. At the same time, the introduction of ultrasound can also solve problems such as weak convective mixing and low concentration of active free radicals produced by oxidant decomposition. The ultrasound and jet combined system has a significant synergistic effect, and the two enhanced technologies are integrated with each other to form a more efficient, more stable and more industrially promising organic matter degradation device in sodium aluminate solution.

[0021] Beneficial effects of the utility model:

[0022] (1) The utility model solves the technical difficulties of the traditional chemical oxidation method by coupling the ultrasound and jet combined system, and can effectively enhance the degradation of organic impurities in the sodium aluminate solution. It has the advantages of high mass transfer efficiency, long contact time, simple operation, and easy industrialization.

[0023] (2) In the utility model, the ultrasonic device solves the problems of weak convection mixing and low concentration of active free radicals generated by oxidant decomposition through processes such as high-temperature pyrolysis, free radical oxidation, supercritical water oxidation and sonic mechanical effect, and enhances the attack frequency of active free radicals, thereby significantly improving the degradation rate of organic matter in sodium aluminate solution;

[0024] (3) In the utility model, since the aperture at the outlet of the jet device becomes narrower, a high-speed micro jet can be formed at the end. This process can form two low-pressure areas before and after: one is the tangential area when the jet is formed; the other is the vortex area formed when the jet enters a relatively static fluid. This low-pressure area can cause the oxidant liquid flow to be subjected to strong physical and chemical effects and transformed into extremely small micro droplets, significantly increasing the reaction rate of the oxidant and organic matter.

The raw material liquid (organic impurities in the sodium aluminate solution) undergoes ultrasonic oxidation reaction under the oxidation conditions of the oxidant, and the reaction temperature is monitored in real time by a temperature sensor. The generated gas escapes from the gas outlet 19. When the sodium aluminate solution containing organic impurities completes the reaction in the ultrasonic reaction chamber 13, the sodium aluminate solution after impurity purification flows out from the sodium aluminate solution outlet 16, and the remaining liquid and precipitated crystals flow out through the impurity liquid outlet 17.

[0031] Example 2: The coupling device for ultrasonic enhanced degradation of organic impurities in sodium aluminate solution in this example is basically the same as the coupling device for ultrasonic enhanced degradation of organic impurities in sodium aluminate solution in Example 1, except that:

[0032] The jet pipeline includes a jet liquid / gas inlet pipe 1, a jet vacuum pump 4 and a jet tail pipe 5 which are connected in sequence. The jet liquid / gas inlet pipe 1 is externally connected to a liquid / gas storage tank.

[0040] First, the transducer contains piezoelectric crystals or piezoelectric ceramic materials. When an external alternating voltage (high-frequency electrical signal) acts on these materials, they will generate mechanical vibrations, namely ultrasonic waves, due to the piezoelectric effect. These mechanical vibrations propagate outward through the surface of the transducer. Subsequently, the ultrasonic probe can amplify the particle displacement or velocity of the mechanical vibration, thereby amplifying the amplitude by multiples and reducing the resonant impedance, and finally introducing high-frequency ultrasonic waves into the ultrasonic reaction chamber.
