Referring to fig. 1, the present embodiment provides an aluminum ash hydrolysis apparatus, including a first hydrolysis tank 1, a second hydrolysis tank 2 and a third hydrolysis tank 3 which are sequentially communicated, and the first hydrolysis tank 1, the second hydrolysis tank 2 and the third hydrolysis tank 3 are sequentially communicated along the same horizontal direction. The first hydrolysis tank 1 is provided with a feed inlet 11 to feed through the feed inlet 11 and into the first hydrolysis tank 1, the second hydrolysis tank 2 and the third hydrolysis tank 3 in this order. In this embodiment, the feed inlet 11 of the first hydrolysis tank 1 is used for the addition of aluminium ash and water. Specifically, the aluminum ash is crushed by a double-roller crusher, the granularity is required to be less than or equal to 0.5cm, and the mass ratio of the reaction material to water is 1:2-1:10 as the reaction material, so that the aluminum ash can better perform hydrolysis reaction.
After entering the first hydrolysis tank 1 through the feed inlet 11, the mixture of aluminum ash and water flows to the second hydrolysis tank 2 while undergoing a preliminary hydrolysis reaction, finally flows to the third hydrolysis tank 3, and undergoes a hydrolysis reaction by taking the third hydrolysis tank 3 as a main hydrolysis tank. The first hydrolysis tank 1, the second hydrolysis tank 2 and the third hydrolysis tank 3 which are sequentially communicated are arranged, so that the mixture can flow and initially react in the process of flowing from the first hydrolysis tank 1 to the second hydrolysis tank 2 and the third hydrolysis tank 3, and the third hydrolysis tank 3 is used as a main reaction tank. Therefore, the embodiment can realize continuous feeding, and greatly improve the production efficiency.
In this embodiment, the feed inlet 11 is located at the upper part of the side wall of the first hydrolysis tank 1, so that more reaction materials can be conveniently added.

The tops of the first hydrolysis tank 1 and the second hydrolysis tank 2 are both provided with an exhaust device 6 for the discharge of ammonia gas. Because the steam channel 5 is arranged between the third hydrolysis tank 3 and the second hydrolysis tank 2, the steam in the third hydrolysis tank 3 can be introduced into the second hydrolysis tank 2, so that the reaction rate in the second hydrolysis tank 2 and the discharge of ammonia in the second hydrolysis tank 2 are quickened by utilizing the steam, the forward progress of the hydrolysis reaction is prevented from being influenced, the reaction rate is quickened, and the reaction time is shortened.
One end of the steam channel 5 is arranged at the top of the third hydrolysis tank 3 and is communicated with the interior of the third hydrolysis tank 3, the other end of the steam channel 5 passes through the top of the second hydrolysis tank 2 and extends to the inner bottom of the second hydrolysis tank 2, and a steam exhaust fan 51 is arranged in the steam channel 5. The steam exhaust fan 51 draws steam in the third hydrolysis tank 3 into the second hydrolysis tank 2 to accelerate the discharge rate of ammonia gas and the reaction rate in the second hydrolysis tank 2.
The exhaust device 6 comprises an exhaust pipe 61, the top parts of the first hydrolysis tank 1 and the second hydrolysis tank 2 are respectively provided with an exhaust pipe 61, and the exhaust pipe 61 is provided with an exhaust fan 62 so as to facilitate the discharge of gas in the first hydrolysis tank 1 and the second hydrolysis tank 2.

In the hydrolysis reaction of the embodiment, the temperature of the first hydrolysis tank 1 is lower, the reaction is more intense when the temperature is controlled to be less than or equal to 60 ℃ and the content of active substances in the aluminum ash is higher, the first hydrolysis tank 1 is controlled to be lower, the intensity of the reaction can be slowed down to a certain extent, and meanwhile, the solid-liquid ratio of the aluminum ash and water in the first hydrolysis tank 1 can be adjusted to avoid the excessive intensity of the reaction. In the case of severe reaction caused by higher content of active substances in the aluminum ash, the reaction is relieved after the primary reaction. The water added in the first hydrolysis tank 1 can be the wastewater of the recovery treatment so as to avoid resource waste. The temperature of the second hydrolysis tank 2 is controlled to be more than or equal to 80 ℃, and ammonia gas generated by the primary hydrolysis reaction can be effectively discharged due to the introduction of steam. The hydrolysis temperature of the third hydrolysis tank 3 is controlled to be more than or equal to 90 ℃ so as to accelerate the hydrolysis rate.
