Abstract
The utility model relates to an internally circulating carbonator, which belongs to the technical field of chemical equipment. The utility model is characterized in that based on the traditional carbonator, a plurality of sieve plates are arranged at the upper part of the inside of the carbonator; a central circulating cylinder is arranged at the lower part inside the carbonator, and a bacterium cap at the lower part of the carbonator is sheathed in the central circulating cylinder, so the bacterium cap and the carbonator body are partitioned. A CO2 gas inlet pipe is led into the central circulating cylinder, and the carbonator with circulatory flow of external cooling type natural circulation is formed. The utility model mainly for producing sodium bicarbonate has the advantages of stable technological condition, good crystalline grain size, simple operation, long production period and high production capacity.
Description
The utility model is a kind of internal circulating carbonator, belongs to the chemical industry equipment field.
The carbonating tower of traditional mode of production sodium bicarbonate generally is that some caps are installed in tower body, at cooling of the bottom of tower body and feeding CO
2Gas.Because this type of tower is at the whole bottom of tower body crystallisation by cooling, thereby its mass-and heat-transfer is poor; Because CO
2Stirring influenced the crystallization of sodium bicarbonate; Also heterodyne of the absorptivity of this tower in addition; This output of column is low in a word.
The purpose of this utility model is to utilize absorptive character, mass-and heat-transfer performance and crystal property, the production cycle of improving carbonating tower to improve the carbonization output of column.
Internal circulating carbonator of the present utility model is at intravital middle part of tower and bottom some caps to be housed; Cooling jacket is equipped with in outer bottom at tower body; Some sieve plates are equipped with on the intravital top of tower; A central circulating barrel is equipped with in the intravital bottom of tower, with the cap of tower body bottom cover therein, separates with tower body; CO
2Gas inlet pipe feeds central circulating barrel; Central authorities' circulation of this internal circulating carbonator is a cylinder type tube.
This internal circulating carbonator is according to crystallization theory and secondary nucleation principle, and the outer cooled carbonating tower with routine is designed to external-cooling type natural circulation carbonating tower, has set up sieve plate in order to strengthen to absorb.This tower utilizes the inside and outside air content difference of central circulating barrel, causes the severe difference as impellent, carries out natural circulation, comes enhancing mass and heat transfer.Simultaneously cooling and absorbing is separated, alleviated cooling section gas violent stirring and destroyed crystalline polamer, the process of cooling degree of supersaturation is even.The stable process conditions of this tower, grain size number is good, simple to operate, the production cycle is long, throughput is big.This tower is mainly used in production sodium bicarbonate.
Figure is the diagrammatic cross-section of the utility model internal circulating carbonator.
Embodiment: (seeing figure)
Internal circulating carbonator of the present utility model is that two-layer sieve plate 2 is equipped with on the top in tower body 1, its middle part and bottom are equipped with 15 caps 3 successively, central authorities' circulating barrel 24 is the cylinder type tube, be contained in the bottom in the tower body 1, and therein with cap 3 cover of tower body 1 bottom, separate with the outer wall of tower body 1, cooling jacket 5, CO are equipped with in the outer bottom of tower body 1
2Gas inlet pipe 6 feeds central circulating barrel 4, and alkali lye import 7, steam outlet 8 and magma outlet 9 are housed respectively in the upper and lower of tower body 1 in addition.During the work of this tower, in cooling jacket 5, feed recirculated cooling water; Alkali lye is sent into CO from tower body 1 top
2Gas is sent into from the bottom, CO
2Gas carries out crystallisation by cooling from central circulating barrel 4 its outer walls of inflow and 1 of tower body after central circulating barrel 4, cap 3 and sieve plate 2 are fully absorbed by alkali lye, magma flows out from the bottom of tower body 1.
