Sulfur fumigation neutralizer and method for sulfur fumigation neutralization reaction by the same

Abstract

The invention discloses a sulfur fumigation neutralizer, which includes a juice chamber and a suction chamber. Several cane juice honeycomb ducts are arranged at an interval between the juice chamber and the suction chamber, the upper ends of the cane juice honeycomb ducts are connected to the juice chamber, the lower ends of the cane juice honeycomb ducts are connected to the suction chamber through nozzles, and the cane juice honeycomb ducts are also equipped with valves. The process using the sulfur fumigation neutralizer to carry out sulfur fumigation reaction consists of: (1) letting cane juice enter the juice chamber, and then distributing the cane juice into each cane juice honeycomb duct; and (2) jetting the cane juice to the suction chamber through the nozzles to form a stable negative pressure, then sucking sulfur dioxide gas, and mixing the cane juice and sulfur dioxide gas in the suction chamber to form a gas-liquid mixed flow. The sulfur fumigation neutralizer and the process provided by the invention can effectively improve the sulfur sucking efficiency, stabilize sulfur fumigation intensity, improve the cleaning efficiency of cane juice, reduce sulfur consumption, lower sulfur dioxide residue of sugar factory cane juice, reduce soluble calcium salt in the cane juice, lower the production cost and ensure the sulfur content of white granulated sugar, thus guaranteeing the quality of finished sugar product.

Description

technical field [0001] The patent of the present invention relates to a production equipment in the field of sugar cane sugar production, in particular to a sulfur fumigation neutralizer in a sugarcane sugar factory and a method for carrying out sulfur fumigation neutralization reaction. Background technique [0002] The cane juice sulfur fumigation neutralization in the sulfite sugar factory is one of the key technologies in the whole production process. At present, most sugar factories use a vertical pipeline cane juice sulfur fumigation neutralizer, which basically uses a multi-nozzle neutralizer. Some also use a single-nozzle neutralizer. This traditional sulfur fumigation neutralizer has many defects, such as slow neutralization reaction speed, large impact by fluctuations in squeezed volume, poor stability of sulfur fumigation strength, etc., resulting in a decrease in the sulfur dioxide content of white granulated sugar. Many other issues. [0003] In recent years, t...

AI Technical Summary

Problems solved by technology

However, the residual sulfur dioxide in the white granulated sugar produced by some sugar factories is relatively high, approaching or even exceeding the national standard, which has become a major technical problem that sugar factories urgently need to solve
