Embodiment Construction

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

[0029] like figure 1 and figure 2 As shown, the sulfur fumigation neutralization reaction tower includes a sulfur fumigation tail pipe 1, a tank body 2, a gas dispersion pipe 3, and a lime milk adding pipe 4; 2. The interior is divided into 5 reaction layers arranged up and down, and from top to bottom, it is the top reaction layer, No. 2 reaction layer, No. 3 reaction layer, No. 4 reaction layer, and bottom reaction layer; Straight juicing pipes 6, the juicing pipes 6 of each layer are staggered; the sulfur fumigation tail pipe 1 is located on the uppermost reaction layer, and the sulfur fumigation tail pipe 1 comprises the lime milk adding port arranged on it; The top and each clapboard 5 are provided with air-diffusing pipes 3, and the height of the air-diffusing pipes 3 on each clapboard 5 is higher than the height of the juice-passing pipe 6; Inside the reacti...

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 production, in particular to a sulfur-fumigated neutralization reaction tower. Background technique [0002] In the sulfite sugar production process, the neutralization reaction is the key link in the purification of the sugar juice. The principle is to add sulfur dioxide and lime milk to the sugar juice to react to form calcium sulfite to absorb non-sugar impurities and achieve the purpose of cleaning the sugar juice. [0003] The effect of neutralization reaction has an important influence on the quality and yield of white sugar by sulfite method. The current sulfite process sugar mills usually add lime milk to the tail pipe of the pipeline sulfur fumigator after sulfur fumigation of the sugar juice, and then enter a diffuser barrel for diffuse air and simple mixing. Due to the large amount of sulfur dioxide and lime milk When added to the sugar juice almost at the same time, the initial concentration...
