Description

Reverse filling-up pot rapidly and efficiently

Technical field

The utility model relates to the equipment that is applied to clarifying syrup in a kind of Closed Circulation in Sugar Production, especially a kind of reverse filling-up pot rapidly and efficiently.

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 non-sugared impurity 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 the very big influence of follow-up peace and quiet generation, directly influence 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 utility model provides a kind of reverse filling-up pot rapidly and efficiently, and this filling-up pot can solve the deficiency of sulfurous method cleaning technique well; Can remove impurity insolubles in the sulfurous method mixing juice again, guarantee the purpose of the good peace and quiet effect of syrup, for subsequent handling provides better good syrup.

The technical scheme that its technical problem that solves the utility model adopts is: CO ₂Inlet pipe from top to bottom enters into the distribution endless tube, adds lye and tangentially enter CO in the middle of filling-up pot ₂Gas adds lye and enter the back to dirty, CO in the middle of jar from distribution endless tube bubbling up ₂Thereby up with add lye and contact to the convection current of dirty formation backmixing.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 reverse filling-up pot rapidly and efficiently 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, last grid distributor is located at the centre of full charge device, and following 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 at down under the 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 attitude with last grid distributor.

The master who is located at predefecation juice pipe top adds Hui Chu and last 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 is along to the endless tube that distributes, with the distribution rings sealing of tube together.

The beneficial effects of the utility model are: 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 following 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 ₂The specific absorption height, 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, and it is more to generate granular calcium carbonate, thereby reaches better full charge effect.Can better remove non-sugared impurity 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.
