Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 with figure 2 As shown, the sulfur fumigation neutralization reaction tower includes a sulfur fumigation tailpipe 1, a tank body 2, an air diffuser pipe 3, and a milk of lime addition pipe 4; the partition plate 5 in the tank body 2 is provided with 4 pieces, and the vertical tank body 2. The interior is divided into 5 reaction layers arranged up and down. From top to bottom, they are top reaction layer, No. 2 reaction layer, No. 3 reaction layer, No. 4 reaction layer, and bottom reaction layer; Straight juice passing pipes 6, the juice passing pipes 6 of each layer are distributed alternately; the sulfur smoked tail pipe 1 is located on the uppermost reaction layer, and the sulfur smoked tail pipe 1 includes the lime milk inlet arranged thereon; the tank body 2 The top and each dividing plate 5 are provided with diffuser pipes 3, and the h...

Abstract

The invention aims to provide a sulphitation and neutralization reaction tower. The sulphitation and neutralization reaction tower comprises a sulphitation tail pipe, a tank body, air dispersing pipes and a lime milk adding pipe, wherein more than one transverse partition plate is arranged in the vertical tank body, and the tank body is divided into more than two reaction layers by the partition plates. A vertical multilayer design structure is adopted, so that a sulphitation and neutralization reaction can be more balanced and controllable, and adverse effects brought by excessively high concentration of local lime milk are avoided at the greatest extent; and meanwhile, with cooperation of pH sampling and full mixing of each layer, the controllability of the pH value of each reaction layer is further strengthened. The tower is scientific and reasonable in structure collocation, and has extremely high practical value; and compared with the prior art, the tower is brand-new in design idea, and has distinguishing substantive characteristics and significant progresses.

Description

technical field [0001] The invention relates to the field of sugar cane sugar production, in particular to a sulfur fumigated neutralization reaction tower. Background technique [0002] In the sulfite sugar production process, neutralization reaction is the key link in the purification of sugar juice. The principle is to add sulfur dioxide and milk of lime to the sugar juice to form calcium sulfite to absorb non-sugar impurities and achieve the purpose of cleaning sugar juice. [0003] The effect of neutralization reaction has an important influence on the quality and sugar yield of white sugar produced by sulfite process. In current sulphite sugar factories, after sulfur fumigation, milk of lime is added to the tailpipe of the pipeline sulfur fumigation device, and then enters an air diffuser tank for degassing and simple mixing. Due to the large amount of sulfur dioxide and milk of lime Adding sugar juice almost at the same time, the initial concentration of the reaction...
