Abstract

The invention aims to provide a progressive stoving neutralization reaction device, comprising a box body, an exhaust port, a tube diffuser, a stove tail tube, a lime milk adding tube, an ash adding actuator, more than one separator and a pH control device, wherein the box body is internally divided into more than two reaction layers by the separator in the horizontal direction; and the pH control device is used for detecting the pH of mixed sugarcane juice in the box body and controlling the dosage of the lime milk according to pH information, thus keeping the pH value of the mixed sugarcane juice stable. The invention also provides a stoving neutralization reaction method, wherein pH detection and control are performed on the sugarcane juice in reaction through the pH control device, so that the pH of the sugarcane juice after reaction is kept in a predetermined range. The progressive stoving neutralization reaction device and method provided by the invention have the characteristics that the pH of the sugarcane juice is regulated and controlled in sections and the reaction efficiency of the neutralization reaction is enhanced through a stirring device, so that the pH of the sugar juice is stabilized, the cleaning efficiency is improved and the reaction time is prolonged; and therefore, the device and the method play an important role in improving the product quality and the sugar yield of a sugar refinery.

Description

technical field [0001] The invention belongs to a neutralization reaction device in the field of sugarcane sugar production by sulfite method, and in particular relates to a progressive sulfur fumigation neutralization reaction device and method. Background technique [0002] In the sulfite sugar production process, the neutralization reaction is the key link in the purification of cane juice. The principle is to add sulfur dioxide and milk of lime to the sugar cane juice to form calcium sulfite to absorb non-sugar impurities and achieve the purpose of cleaning the sugar cane 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 the current sulfite sugar factory, after the cane juice is sulfur-fumigated, milk of lime is added to the tailpipe of the pipeline sulfur fumigation device, and then enters an aeration tank for degassing and simple mixing. Due to the large amount ...
