Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problem that the existing quicklime digestion device consumes more energy, and to provide an energy-saving quicklime digestion device
The digested lime milk slurry is output from the slurry outlet, falls into the energy-saving device, and impacts the rotating impeller, which can drive the rotating impeller to rotate. The rotational kinetic energy of the rotating impeller can be used as the power source for the rotation of other rotating parts of the device, and the potential energy of the slurry It is converted into kinetic energy, which effectively reduces the energy consumption of the device and solves the technical problem of high energy consumption of the existing quicklime digestion device. Quicklime is fully digested

Abstract

The invention relates to mechanical equipment in the light calcium production process, in particular to an energy-saving quick lime slaking device. The energy-saving quick lime slaking device comprises a tank body and a stirring mechanism, a water injection opening, a feeding opening and a slurry outlet are formed in the tank body, an energy saving device is arranged below the slurry outlet and comprises a box body and a rotary impeller arranged in the box body, and the slurry outlet is communicated with the box body. Lime milk slurry subjected to a slaking reaction is output out of the slurry outlet and falls into the energy saving device to impact on the rotary impeller, the impeller can be driven to rotate, rotation of the impeller can serve as a power source for rotation of other rotating positions of the device, the potential energy of the slurry is converted into kinetic energy, energy consumption of the device is effectively reduced, and the technical problem that an existing quick lime slaking device is large in energy consumption is solved.

Description

technical field [0001] The invention relates to mechanical equipment in the production process of light calcium, in particular to an 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 for 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 quicklime digestion ...
