Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of defoaming in the hydrolysis of secondary aluminum ash, in particular to a defoaming device for a hydrolysis reactor of secondary aluminum ash. Background Technique
[0002] Aluminum ash is generated in the molten aluminum processing process, mainly including primary aluminum production (electrolytic aluminum), aluminum alloy production, waste aluminum recycling and aluminum ash treatment process. Generally, according to the different metal aluminum content in aluminum ash, it can be divided into primary aluminum ash and secondary aluminum ash. The aluminum slag scraped out from the melting furnace is called primary aluminum ash, which appears grayish-white in appearance and is mainly a mixture composed of metallic aluminum and aluminum oxide. The aluminum content can reach 15% - 70%, and it is also called "white aluminum ash"; secondary aluminum ash is the waste after extracting metallic aluminum from primary aluminum ash, and its main components are aluminum oxide, aluminum nitride, metallic aluminum, salts (such as NaCl, KCl, etc.) and other components. Because it solidifies into a block, it is also called "salt cake". In 2018, the aluminum processing output in China was 58.32 million tons, and the recycled aluminum output was 6.9 million tons, generating about 1.6 million tons of secondary aluminum ash. According to the "National Hazardous Waste List" in 2021, secondary aluminum ash belongs to hazardous solid waste (HW48 non-ferrous metal smelting waste, 321-025-48 salt slag and dross generated in the electrolytic aluminum process).
[0003] However, in the existing defoaming device for the hydrolysis reactor of secondary aluminum ash, during use, in the hydrolysis process of secondary aluminum ash, there is a situation of concentrated exothermic reaction. A large amount of gas-liquid mixture is generated in the concentrated reaction stage and enters the tail gas treatment system. The concentrated release of a large amount of gas-liquid mixture is extremely likely to cause the material to overflow from the reactor, affecting the product yield and hydrolysis effect. The large number of bubbles generated in this stage can only be controlled by adjusting the stirring speed, steam supplement temperature, reserved space in the reactor, etc. Content of the Utility Model
[0004] The utility model aims to solve the problem that in the existing technology during use, in the hydrolysis process of secondary aluminum ash, there is a situation of concentrated exothermic reaction. A large amount of gas-liquid mixture is generated in the concentrated reaction stage and enters the tail gas treatment system. The concentrated release of a large amount of gas-liquid mixture is extremely likely to cause the material to overflow from the reactor, affecting the product yield and hydrolysis effect. The large number of bubbles generated in this stage can only be controlled by adjusting the stirring speed, steam supplement temperature, reserved space in the reactor, etc. For this reason, the utility model provides a defoaming device for a hydrolysis reactor of secondary aluminum ash, which can achieve the purpose of bubble elimination and accelerating the reaction process by controlling the vibration frequency and intensity of three ultrasonic vibrating rods with different frequencies.

[0007] Preferably, the surface size of the inner wall of the positioning groove is identical to the surface size of the outer wall of the positioning block.

Embodiment
[0031] Please refer to Figure 1 - Figure 6, as shown in the figure, on the basis of the first embodiment, an installation component 800 is assembled on the outer wall of the reactor 100. The installation component 800 includes a fixing sleeve 801 which is installed on the surface of the reactor 100. A positioning groove 802 is formed on the outer wall of the fixing sleeve 801. A first rubber sleeve 803 is fixedly connected to the inner wall of the fixing sleeve 801. An airbag 804 is fixedly connected to the outer wall of the fixing sleeve 801. A connecting block 805 is fixedly connected to the outer wall of the fixing sleeve 801. An air chamber 806 is formed on the inner wall of the connecting block 805. A push rod 807 is slidably connected to the inner wall of the air chamber 806. A ventilation groove 808 is formed on the inner wall of the fixing sleeve 801. An installation sleeve 809 is fixedly connected to the outer wall of the ultrasonic vibration rod 400. The air inside the air chamber 806 enters the inside of the airbag 804 through the ventilation groove 808. After the airbag 804 is inflated and expanded, it fits tightly with the groove 811, which can improve the airtightness between the installation sleeve 809 and the fixing sleeve 801. A positioning block 810 is fixedly connected to the outer wall of the installation sleeve 809. A groove 811 is formed on the bottom outer wall of the installation sleeve 809. A second rubber sleeve 812 is fixedly connected to the inner wall of the installation sleeve 809. A rotating block 813 is rotatably connected to the outer wall of the installation sleeve 809. A clamping block 814 is fixedly connected to the outer wall of the rotating block 813. A handle 815 is fixedly connected to the outer wall of the rotating block 813. Pulling the handle 815 drives the rotating block 813 to rotate on the surface of the installation sleeve 809, so that the clamping block 814 is engaged with the connecting block 805. At the same time, the first rubber sleeve 803 and the second rubber sleeve 812 will be pressed against each other. After the rubber is pressed, it will generate tension, which will thus exert a thrust on the installation sleeve 809, making the engagement between the clamping block 814 and the connecting block 805 more firm and improving the overall usability of the device.
[0032] In use, on the basis of the first embodiment, when installing the ultrasonic vibrator 400, first insert one end of the ultrasonic vibrator 400 into the inside of the fixed sleeve 801, so that the positioning block 810 on the surface of the mounting sleeve 809 enters into the positioning groove 802 on the surface of the fixed sleeve 801. At the same time, the surfaces of the first rubber sleeve 803 and the second rubber sleeve 812 are mutually attached. Then, pull the handle 815 to drive the rotating block 813 to rotate on the surface of the mounting sleeve 809, so that the locking block 814 is engaged with the connecting block 805. At the same time, the first rubber sleeve 803 and the second rubber sleeve 812 will be mutually extruded. After the rubber is extruded, it will generate tension, which will thus exert a thrust on the mounting sleeve 809, making the engagement between the locking block 814 and the connecting block 805 more firm. During the process of the locking block 814 being engaged with the connecting block 805, the locking block 814 will push the push rod 807 to move into the air chamber 806, thereby squeezing the air inside the air chamber 806, so that the air inside the air chamber 806 enters the airbag 804 through the ventilation groove 808. After the airbag 804 is inflated and expands, it fits tightly with the groove 811, which can improve the airtightness between the mounting sleeve 809 and the fixed sleeve 801, and improve the overall usability of the device.
