CN2038906U - Wet type high-temperature slaker of quick lime - Google Patents

Abstract

The utility model relates to the wet type high-temperature slaker of quick lime. The wet type high-temperature slaker of quick lime is provided with a digesting section and a dilute section. A propelling mode on the digesting section replaces a stirring mode in the prior art, which not only overcomes the disadvantages that the prior art can not completely digest spherical quick lime, which causes the clogging of running, the waste of the quick lime, etc., but also the utility model has no deslagging. The utility model has the advantages of small size, high quality, good job conditions of operators, and good dispersancy; the wet type high-temperature slaker of quick lime is easy to realize automation.

Description

Wet type high-temperature slaker of quick lime

The utility model relates to a kind of thermophilic digestion equipment of unslaked lime.

Before the utility model was made, the digestion method and the equipment of unslaked lime mainly contained dry method digestion method and equipment, wet method low-temperature digestion method and equipment thereof, wet method thermophilic digestion and equipment thereof both at home and abroad.The former is mainly lime powder factory and adopts, and both are mainly the lime treatment system employing of water the back.At present at home more employing be wet method low-temperature digestion method, this method is that block lime is placed in the bigger digestion machine, rotate on one side, add water on one side, the newborn good dispersity of stone fire that this method obtains helps the softening reaction of lime treatment of water, but because the bed drain purge of the newborn system of system is big, system complex, slagging-off is difficult to realize that reasons such as mechanize, operator work under hard conditions have the trend that progressively is eliminated.The wet method thermophilic digestion is because to have a digestive organ volume little, milk of lime dispersed better, advantage such as it is simple to make newborn system, realizes automatization easily, operator's good operation conditions and being subject to people's attention.But before the present invention made, not corresponding suitable high-temperature digester occurred.China once introduced a kind of high-temperature digester (referring to Fig. 1) of the U.S., it is applicable to powdery unslaked lime, actual motion shows, its operating performance is bad, major cause is: the thermophilic digestion section of digestive organ adopts alr mode, make be mingled with in the milk of lime can not complete digestion spherical unslaked lime, cause operation to stop up and the waste of unslaked lime.

Disadvantage at above-mentioned high-temperature digester, the utility model has designed a kind of new type high temperature digestive organ that replaces alr mode in the thermophilic digestion section with propulsion mode, not only overcome the shortcoming in the prior art, and there is not a deslagging, operator's good operation conditions, realize automatization easily, the milk of lime dispersiveness of preparation is better than above-mentioned various technology.

Now the utility model high-temperature digester technical characterictic is described below:

This digestive organ mainly is divided into digestion section and dilution section, on digestion section 11, be provided with water inlet pipe 1, unslaked lime import 2 interface 4 of bleeding, spiral propeller 3 is contained in the digestion section 11, the water and the unslaked lime of packing into is only played prograding and do not carry out any stirring, to prevent caking.The dilution section is provided with water inlet pipe 5,6,7, and stirrer 8 goes out latex dust 9, vapor pipe 10.After the slaked lime slurries that the digestion section is come out enter the dilution section, add water towards rare extremely required concentration from water inlet pipe 5,6,7.On the main shaft 12 of stirrer 8 stirring arm 13 is housed, stirring arm 13 symmetric arrangement.Agitator main shaft in spiral propeller axis in the digestion section and the dilution section is on same axis, and its rotating speed is controlled by buncher.

Now that description of drawings is as follows:

Fig. 1: the utility model high-temperature digester sectional view.

Fig. 2: China introduces U.S.'s high-temperature digester synoptic diagram.

Wherein: 1, water inlet pipe 2, unslaked lime import 3, spiral propeller 4, the interface 5 of bleeding, water inlet pipe 6, water inlet pipe 7, water inlet pipe 8, stirrer 9, go out latex dust 10, vapor pipe 11, digestion section 12, stirrer main shaft 13, stirring arm 14, emulsification lime 15, stirrer 16, lime-ash conveyor

This digester proves that through on probation digestion effect is good, and digestion rate in service is fast, do not stop up, and the milk of lime good dispersion, simple to operate, welcome by the operations staff.

Claims (3)

1, a kind of wet method high-temperature digester of unslaked lime, it is characterized in that constituting by digestion section and dilution section, digestion section is provided with water inlet pipe, unslaked lime import, the interface of bleeding, and in the digestion section spiral propeller is housed, and the dilution section is provided with water inlet pipe, goes out latex dust, stirrer is housed in the evacuated tube, dilution section.

2,, it is characterized in that the stirrer in the section of dilution is provided with the stirring arm of symmetric arrangement according to the wet method high-temperature digester of a kind of unslaked lime described in the claim 1.

3,, it is characterized in that the spiral propeller main shaft in the section of digestion and dilute the interior stirrer main shaft of section on same axis that its rotating speed is controlled by buncher according to the wet method high-temperature digester of a kind of unslaked lime described in the claim 1.
