[0071] a. Aft...

Embodiment 3

[0075] Such as Figure 1~Figure 4 As shown, on the basis of Embodiment 2, the liquid level control module is further optimized, and a variable frequency pump control circuit is added to the liquid level control module. The frequency conversion pump control circuit is used to control the frequency conversion juice pump 8 to be turned on or off. The method includes the following steps:

[0076] a. After sulfur fumigation and ashing, the cane juice enters the tank 1 through the sulfur fumigation neutralization reactor 2, and the liquid level rises continuously with the inflow of the cane juice, and the liquid level transmitter 6 detects the liquid in the tank 1 Level information, and convert the liquid level information into an analog current signal and transmit it to the PID regulator;

[0077] b. After the PID regulator receives the liquid level information, A / D converts the received analog current signal into a liquid level digital signal, performs difference calculation wit...

Abstract

The invention aims to provide a stoving neutralizing auxiliary reaction tower. The stoving neutralizing auxiliary reaction tower comprises a cylindrical tank body, a stoving neutralizing reactor, a tube diffuser, a juice outlet pipe, a variable frequency juice outlet pump and a liquid level control device. By using the stoving neutralizing auxiliary reaction tower, the defects of the conventional neutralizing reaction device in a sugar refinery are overcome, and the problem of incomplete chemical reaction of the cane juice subjected to stoving liming is solved. The invention also provides a method for carrying out stoving neutralizing reaction by using the stoving neutralizing auxiliary reaction tower. According to the method, the stoving neutralizing auxiliary reaction tower is reasonably utilized, so that the standing time of the cane juice subjected to stoving liming is greatly increased, the uniformity of the cane juice is improved, the reaction of neutralized juice is more complete, and remarkable effects of improving the syrup purity, reducing the color value of white sugar and turbidity and lowering the sulfur dioxide residues are achieved.

Description

technical field [0001] The invention relates to the field of sugar cane sugar production, in particular to a sulfur fumigated neutralization auxiliary reaction tower. Background technique [0002] The sulfite method of sugar production mainly relies on the reaction of sulfur dioxide, lime and impurities in sugarcane juice to form flocculated particles, and the solid-liquid separation is carried out through the settler to achieve the purpose of clarifying the sugarcane juice. have a crucial impact. [0003] At present, the sulfur fumigation neutralization reaction system used in the sulphite sugar production does not design an auxiliary reactor, only the sulfur fumigation neutralization reactor is used, the reactor volume is small, and the residence time of the sugar juice in the reactor is only a few For ten seconds, it only plays the role of preliminary mixing of materials in function. [0004] The sugar juice is sent to the neutralization juice tank after passing through...
