Abstract

The invention discloses a quick high-efficiency reverse carbonation tank for sugar manufacturing industry, which is characterized in that the carbonation tank is divided into three parts by an upper distribution plate and a lower distribution plate; a CO2 gas inlet tube is led into a distribution loop tube from top to bottom; a prelimed juice is subjected to principal liming and then fed into the middle of the carbonation tank in the tangential direction; a slag removal port is arranged at the bottom of the tank; CO2 gas bubbles upwards through the distribution loop tube; the limed juice moves into the middle of the carbonation tank in the tangential direction and then flows downwards, so that the CO2 bubbling upwards and the limed juice flowing downwards realize reverse operation. According to the quick high-efficiency reverse carbonation tank, the opposite flow directions of the CO2 and the limed juice realize quick high-efficiency carbonation based on favorable circulating mixed convection flows in reverse directions, ensure the sufficient and uniform reaction and achieve high CO2 absorptivity; the quick high-efficiency reverse carbonation tank has the advantages of low carbonation liquid level required, small volume, short retention time and high control stability, and can generate more calcium carbonate particles; and the overflowing phenomenon of the tank is less prone to occur. Thus, the quick high-efficiency reverse carbonation tank can achieve better carbonation effect.

Description

Reverse filling-up pot rapidly and efficiently

Technical field

The present invention relates to be applied in a kind of Closed Circulation in Sugar Production the equipment of clarifying syrup, especially a kind of rapidly and efficiently reverse filling-up pot.

Background technology

The syrup CO in present sugar refinery ₂Full charge equipment generally is to be applied to the carbonatation process sugar refining technology, compares less and be applied to sulfurous method.The sulfurous method sugar refining technology is with respect to the carbonatation process sugar refining technology, and the non-sugar impuritiess such as the colloidal impurity in the syrup, Polyphenols, iron ion are many, are difficult to remove fully, and purification effect is lower.Contain the non-sugar of a large amount of impurity in the sulfurous method mixing juice, to follow-up peace and quiet having a huge impact, directly affect quality product, and the CO of sulfurous method mixing juice ₂Full charge compares less, the CO of existing mixing juice ₂Full charge is the novel method of sulfurous method sugar refining technology.

Summary of the invention

In order to overcome the deficiency of existing sulfitation process craft and full charge equipment, the invention provides a kind of rapidly and efficiently reverse filling-up pot, this filling-up pot can solve the deficiency of sulfurous method cleaning technique well; Can remove again impurity insolubles in the sulfurous method mixing juice, guarantee the purpose of the good peace and quiet effect of syrup, for subsequent handling provides better good syrup.

The technical solution adopted for the present invention to solve the technical problems is:

CO ₂Inlet pipe enters filling-up pot, CO from top to down ₂Gas rises after the distribution of distribution endless tube, and the predefecation juice entrance tangentially adds lye toward filling-up pot after the master adds ash, and is past dirty behind cloth annular groove cloth, the CO of rising ₂Gas with add the rapidly and efficiently full charge that lye forms reverse circulation mixed convection toward dirty, full charge juice flows to full charge juice from juice outlet groove and exports out juice.

Add lye and in reverse, fully absorb CO ₂, reaction generates granular calcium carbonate, removes from the bottom slag removing hole when precipitation lime-ash that produces is shut down, and the gas of generation is discharged from the diffuser at top.

Constitutional features is: a kind of rapidly and efficiently reverse filling-up pot comprises that top is the filling-up pot of round shape, lower taper, is characterized in that: the CO that from top to bottom enters is housed in the filling-up pot cylindrical shell ₂Inlet pipe, upper grid distributor is located at the centre of full charge device, and lower grid distributor is located at the columnar bottom of filling-up pot, and the cloth annular groove is located between grid distributor and the full charge device inwall, CO ₂The distribution endless tube is located under the lower grid distributor, and the predefecation juice entrance tangentially enters into filling-up pot from the mid-way of filling-up pot, and the master adds the top that the ash place is located at the predefecation juice pipe.

The cloth annular groove is metal cylinder, is welded on the filling-up pot inwall, is on the same level position with upper grid distributor.The master who is located at predefecation juice pipe top adds Hui Chu and upper grid distributor is level attitude, is connected to the outside of filling-up pot.

CO ₂Inlet pipe is passed the outer wall of filling-up pot to the middle part, and palintrope welds together with the distribution endless tube along to the endless tube that distributes.

Described full charge juice is sugar cane juice or sugar beet juice.

The invention has the beneficial effects as follows: by grid distributor about in the of two filling-up pot is divided into three parts, CO ₂Inlet pipe from top to bottom enters into the distribution endless tube, by lower grid distributor bubbling up, adds lye and tangentially enters behind the filling-up pot mid-way toward dirty CO ₂Flow to add the opposite formation of the lye flow direction reverse, add lye and CO ₂Can well contact absorption reaction, sufficient reacting is even, CO ₂Specific absorption is high, and required full charge liquid level is low, and volume is little, is difficult for tank boil-overs, and the residence time is short, and control is stable, generates granular calcium carbonate more, thereby reaches better full charge effect.Can better remove non-sugar impuritiess such as adding colloidal impurities various in the lye, Polyphenols, iron ion, thereby reach the purpose of guaranteeing the good peace and quiet effect of syrup, for follow-up workshop section provides better good syrup, the better high-quality commerieal sugar of output.
