Secondary aluminum ash denitrification treatment equipment and method

The invention provides secondary aluminum ash denitrification treatment equipment and a secondary aluminum ash denitrification treatment method. The secondary aluminum ash denitrification treatment equipment comprises a grinding device, a slurry pipeline, a gas-liquid separator and a gas collecting pipeline, the slurry pipeline is provided with a slurry inlet end and a slurry outlet end, and the slurry inlet end and the slurry outlet end are both communicated with the grinding device; the gas-liquid separator is arranged on the slurry pipeline and is used for separating gas generated by hydrolysis reaction of the secondary aluminum ash and water; and the gas collecting pipeline is communicated with the gas-liquid separator and is used for collecting gas generated by hydrolysis reaction of the secondary aluminum ash and water. According to the method, wrapping layers on the surfaces of aluminum nitride particles are stripped through the grinding effect, the hydrolysis reaction is continuously and efficiently c
