Abstract

The invention discloses a stoving neutral reaction system which comprises a stoving neutralizer, a reaction barrel and a degassing barrel, wherein the reaction barrel is connected with the stoving neutralizer by virtue of a lime milk pipe, the degassing barrel is connected with the reaction barrel by virtue of a pipeline, the stoving neutralizer is provided with a first cane juice injection pipe and a SO2 injection pipe, and a first juice discharge pipe is arranged on the lower part of the degassing barrel. The system further comprises an absorption tower which is connected with the degassing barrel by virtue of a tail gas pipe, the absorption tower is further provided with a second cane juice injection pipe, a second juice discharge pipe is arranged on the lower part of the absorption tower, residual SO2 in the degassing barrel enters into the absorption tower by virtue of a tail gas pipe, and juice injected into the absorption tower is stoved, so that the tail gas is recycled. Equivalently, the system disclosed by the invention utilizes unspent SO2, so that the use level of sulfur is reduced and the cost and expenditure are saved, and moreover, the surrounding environmental pollution of SO2 gas can be reduced.

Description

technical field [0001] The invention relates to the field of sugar cane sugar production, in particular to a sulfur fumigation neutralization reaction system. Background technique [0002] Sulfurous acid sugar production mainly relies on the reaction of sulfur dioxide, lime and impurities in sugarcane juice to form flocculated particles, which react to form calcium sulfite to absorb non-sugar impurities and achieve the purpose of clarifying cane juice. The clarification efficiency of cane juice has a great influence on the quality of sugar, Scouring recovery has a crucial impact. [0003] At present, the sulfite method sugar factory usually puts milk of lime into the tailpipe of the pipeline sulfur fumigation device after sulfur fumigation, and then enters a diffuser for gas diffusion and simple mixing. Due to the large amount of sulfur dioxide (Sulfur dioxide, SO 2 ) and milk of lime are added to the sugar juice almost at the same time, the initial concentration of the re...
