Method for automatically clearing syrup in conveying and storing processes

Abstract

The invention provides a method for automatically clearing syrup in conveying and storing processes. After syrup is discharged from the former procedure, the syrup is firstly heated to a temperature of 80-85 DEG C and then discharged into a syrup box on +_0.000 layer. Then, the syrup is conveyed into a syrup storage box at the top layer of a sugar boiling building through a main and auxiliary pipeline, and a high-molecular flocculant is added before the syrup enters the syrup storage box. On the +_0.000 layer, gas is absorbed and dissolved through an online pipeline air breather and pressure formed by liquid level height difference. After the syrup enters the syrup storage box at the top layer of the sugar boiling building, impurities and air bubbles in the syrup rise to the top of the syrup storage box and are discharged out, and pure syrup is discharged from the bottom of the syrup storage box. The function of automatically clearing the syrup is increased under the condition of storing the syrup by the syrup storage box. The impurities are effectively removed from the syrup, the syrup purity is improved, the syrup conversion losses are reduced, the quality of a white granulated sugar product is effectively improved, and the economical benefit of a sugar making industry is improved.

Description

technical field [0001] The patent of the present invention relates to sugar making technology, in particular to a method for automatic cleaning of syrup during transmission and storage. Background technique [0002] The development and improvement of syrup air flotation technology is one of the most important advances in modern sugar technology at home and abroad. The earliest phosphorus floating cleaning method has been applied in the 20th century, but it was still only used in sugar refineries until the end of the 1960s, and its stability and effect were not good enough. After the 1970s, due to the development of high-efficiency flocculants, the speed and efficiency of air flotation separation have been greatly improved, and a variety of new technological processes have been successfully studied for cane sugar factories and refined sugar production. Since the end of the 1970s in my country, a number of sugar factories and research units have carried out a lot of research ...

AI Technical Summary

Problems solved by technology

[0010] According to the traditional sugar making process, the crude syrup formed after the sugar liquid is concentrated by the evaporation tank is subjected to secondary sulfur fumigation and then directly pumped to the syrup storage tank on the top floor of the sugar cooking building. The syrup storage tank is only for storage, and the syrup is not used. Further cleaning and impurity removal treatment, fine particles, colloids and other impurities in the syrup seriously affect the sugar cooking effect, such as white sugar turbidity, ash content, sulfur dioxide content and other indicators are too high, the cooking process is difficult, and the sugar recovery rate is low

In order to solve the above problems, some sugar enterprises have adopted the technology of syrup floating and cleaning, but the technology of syrup floating and cleaning needs to add more auxiliary materials such as lime, phosphoric acid, calcium saccharified, flocculant, etc. Complete reaction is very unfavorable for improving the purity of syrup and will affect the recovery rate of scouring. At the same time, this technology also increases the residence time of syrup, resulting in unnecessary loss of sucrose conversion
