Problems solved by technology

[0004] Among them, the rotary digester better solves the shortcomings of the trough-type ash machine. It has a high degree of mechanization and continuous production, but it has a large investment and is only suitable for large-scale production enterprises.
During the operation of the rotary digester, it will also cause problems such as clogging of the discharge hole, clogging of the filter screen, and difficulty in cleaning. Particles are difficult to remove effectively
In order to overcome the above shortcomings, the patent "Particl

Abstract

The invention discloses a wet digestion apparatus for wide size range lime blocks. The apparatus comprises an inlet pipe, a feed liquor distributor, a net chain machine, a slaker, a filter screen, a flush water pump and a flooding nozzle; a net chain on the net chain machine moves at a certain speed, the inlet pipe above the net chain machine delivers lime blocks onto the net chain machine, digestion water above the net chain machine flows out through the feed liquor distributor and splashes down to uniformly wet the lime blocks, lime blocks begin to be digested and disintegrated, the flush water pump pumps out digestive slurries in the slaker, digested substances of the lime blocks are swashed by the flooding nozzle arranged at the end of the net chain machine to form a slurry which flows into the slaker, the slaker is provided with stirring vanes which continue digestion of lime, and the lime slurry overflows to downstream equipment through the filter screen and an overflow pipe. The apparatus provided in the invention can digest lime blocks, basically has no requirements for the particle size of lime blocks, enables total energy consumption to be low and has the advantages of good adaptability, high reliability and a long service life.

Description

technical field [0001] The present invention relates to a wide screening lime block wet digester. Background technique [0002] Lime digester is a special equipment for digesting quicklime (calcium oxide) into lime milk or lime powder. Mainly used in chemical industry, pharmaceutical, alumina, titanium dioxide, power plant desulfurization, papermaking alkali recovery, steelmaking, soda ash manufacturing, metallurgy and other industries. [0003] Lime digestion process includes wet digestion process and dry digestion process. The devices for preparing lime slurry by wet digestion include stagnation type, paddle trough type and rotary type digester. Preparation of Powdered Ca(OH) by Dry Digestion 2 The methods are generally divided into two categories: mechanical stirring digestion, air flow disturbance stirring digestion. [0004] Among them, the rotary digester better solves the shortcomings of the trough-type ash machine. It has a high degree of mechanization and contin...
