Description

Technical Field

[0001] This utility model belongs to the field of anhydrous lithium hydroxide processing technology, specifically relating to a device for treating condensate from anhydrous lithium hydroxide. Background Technology

[0002] Anhydrous lithium hydroxide is a white crystalline or granular powder inorganic strong base compound with the chemical formula LiOH. It belongs to the alkali metal hydroxides and has a molecular weight of approximately 23.95. It is hygroscopic in air and absorbs carbon dioxide to form lithium carbonate. It is highly corrosive and has a pungent taste. Its melting point is 450 to 471°C, its boiling point is 924°C, and its solubility in water at 20°C is 12.8 g / 100 mL. It is slightly soluble in ethanol. It is mainly used in the preparation of lithium salts, alkaline battery electrolytes, lubricating grease additives, and carbon dioxide absorbents.

[0003] Anhydrous lithium hydroxide is mainly prepared through high-temperature dehydration or chemical conversion. The dehydration method requires controlling the airflow temperature and residence time to avoid localized overheating, while the conversion method requires multi-stage impurity removal and drying. The final product must be sealed in moisture-proof packaging. One example, CN219283896U, describes a continuous drying device for producing anhydrous lithium hydroxide. This device can continuously dry lithium hydroxide monohydrate, improving the production efficiency of anhydrous lithium hydroxide. However, it does not treat the condensate and discharges it directly. Given the issue of excessively high pH values ​​in the condensate due to trace amounts of alkaline dust, this condensate cannot be directly reused. Direct discharge would have an environmental impact, and the highly corrosive nature of this condensate would also pose a risk of corrosion to the condensate transport pipelines.

[0020] As a preferred embodiment, the neutralization structure further includes: a neutralization tank 8, a neutralization outlet pipe 9, and a neutralization outlet valve 10; the neutralization tank 8 is installed on the lower wall of the transport pipe 4, the neutralization outlet pipe 9 is installed on the lower wall of the neutralization tank 8, the neutralization outlet valve 10 is installed outside the neutralization outlet pipe 9, an observation window 20 is provided on the outside of the neutralization tank 8, and a heightening support 21 is provided on the outside of the neutralization tank 8.

[0021] As a preferred embodiment, the agitation structure further includes: an agitation shaft 11, an agitation motor 12, and three agitation blades 13; the agitation shaft 11 is installed inside the neutralization tank 8 via bearings, the agitation motor 12 is installed on the upper wall of the neutralization tank 8, and the drive end of the agitation motor 12 is connected to the agitation shaft 11, and the three agitation blades 13 are respectively fixedly installed outside the agitation shaft 11.

[0022] As a preferred embodiment, the inflation structure further includes: an inflation ring pipe 14, six inflation connecting thin pipes 15, an air supply pipe 16, an air storage tank 17, two inflation check valves 18, and a booster pump 19; the six inflation connecting thin pipes 15 are respectively installed outside the neutralization tank 8, the inflation ring pipe 14 is installed outside the six inflation connecting thin pipes 15, one end of the air supply pipe 16 is installed outside the inflation ring pipe 14, and the air storage tank 17 is installed at the other end of the air supply pipe 16, the two inflation check valves 18 are respectively installed outside the air supply pipe 16, and the booster pump 19 is installed outside the air supply pipe 16.

[0023] Working Principle: When using this device, first connect an external AC power source to provide energy to the electrical equipment. Then, connect a matching controller to provide control and operating logic for the equipment. Next, the operator flushes carbon dioxide into the gas storage tank 17 to provide raw materials for the neutralization of condensate. Then, the operator connects the condensate outlet pipe 1 to the condensate-producing equipment for condensate collection. Both the condensate collection tank 2 and the neutralization tank 8 have pressure balancing valves installed on their upper walls. The collection end transport valve 5, the neutralization end transport valve 6, and the neutralization outlet valve 10 are all electrically controlled valves, which can be controlled by the matching controller.

[0024] When the operator starts the device, the condensate collection pump 3 first begins operation. Condensate flows through the condensate outlet pipe 1 into the condensate collection tank 2. The condensate collection tank 2 is equipped with a level sensor. When the condensate volume inside the condensate collection tank 2 reaches a certain level, the condensate is discharged for neutralization. During discharge, the condensate collection pump 3 stops operating, the collection end transport valve 5 and the neutralization end transport valve 6 open, and the transport pump 7 starts operating. Condensate flows through the transport pipe 4 from the condensate collection tank 2 into the neutralization tank 8. When the level sensor inside the condensate collection tank 2 detects that the condensate has been drained, the collection end transport valve 5 and the neutralization end transport valve 6 close. Next, the agitator motor 12 starts operating, driving the agitator shaft 11 and its three external agitator blades 13 to rotate. At this point, the booster pump 19 starts working, extracting carbon dioxide from the storage tank 17 and increasing the pressure of carbon dioxide gas in the gas delivery pipe 16. When the gas pressure inside the gas delivery pipe 16 exceeds the threshold of the one-way valve 18, carbon dioxide enters the inflation ring pipe 14 and, under the action of high pressure, enters the neutralization tank 8 through the six inflation connecting thin tubes 15. Simultaneously, under the action of the three agitator blades 13, the carbon dioxide gas is broken into small bubbles, allowing the carbon dioxide to fully contact the condensate, thereby lowering the pH value of the condensate. The principle is that lithium hydroxide and carbon dioxide react to form lithium carbonate precipitate and water. Because the condensate is being stirred, the lithium carbonate precipitate does not adhere to the inner wall of the neutralization tank 8. The neutralization tank 8 is equipped with a pH sensor. When the pH value approaches normal, the operator opens the neutralization outlet valve 10 through the controller, and the condensate mixed with lithium carbonate precipitate enters the prepared container for settling, finally obtaining condensate with a normal pH value and lithium carbonate precipitate. The condensate can be reused, and the lithium carbonate precipitate is collected and centrally treated.
