Abstract

The invention relates to mechanical equipment in a lime production process and particularly relates to a high-temperature energy-saving quick lime slaking device. The device comprises a tank body and a power mechanism, wherein a water inlet and a raw material injection hole are formed in the top of the tank body, a stirring mechanism is arranged in the tank body, and the power mechanism drives the stirring mechanism to rotate; and a slurry outlet is formed in one side of the bottom of the tank body, a screening machine is arranged below the slurry outlet, is connected with a grinding device and is used for separating over-burnt or under-burnt lime and water insoluble impurities in slurry output from the slurry outlet. The separated over-burnt or under-burnt lime enters the grinding device and is adequately ground, and the ground over-burnt or under-burnt lime can reenter the tank body to undergo slaking reaction or to be continuously used as a common industrial raw material.

Description

technical field [0001] The invention relates to mechanical equipment in the lime production process, in particular to a high-temperature energy-saving quicklime digestion device. Background technique [0002] Light calcium is light calcium carbonate, also known as precipitated calcium carbonate. After mixing limestone and white coal in a certain proportion, it is calcined at high temperature, digested with water, carbonized with carbon dioxide, and then centrifugally dehydrated, dried, cooled, crushed, and sieved. The mixture of limestone and white coal is calcined at high temperature to produce quicklime, that is, calcium oxide, and the quicklime is digested by water to produce slaked lime, that is, calcium hydroxide. At present, the quicklime digestion device is generally used in the industry to carry out the digestion reaction. A certain amount of quicklime and a certain amount of water are added to the quicklime digestion device, and an agitator is installed in the qui...
