Embodiment 1

[0040] Embodiment 1: A method for strengthening the neutralization reaction of sugarcane juice by hydraulic micro-oscillation.

[0041] Such as Figure 7 As shown, the method for strengthening the neutralization reaction of sugarcane juice by hydraulic micro-oscillation is a kind of clarification process applicable to cane juice or sugar solution of sulfite method, except that the same process flow as the usual sugarcane juice clarification process includes: In addition to the pre-ashing, primary heating, sulfur fumigation neutralization, secondary heating and sedimentation processes, there is also a hydraulic micro-oscillation intensified sugarcane juice neutralization reaction process between the sulfur fumigation and secondary heating processes. The hydraulic micro-oscillation The enhanced cane juice neutralization reaction process is to use the cane juice or neutralized juice that has passed through the sulfur fumigation neutralization reaction process and the diffuser box...

Embodiment 2

[0043] Embodiment 2: A kind of hydraulic micro-oscillation strengthened sugarcane juice neutralization reaction device composed of two ends of a horn-shaped tube and a small round tube.

[0044] Such as Figure 1-1 to Figure 2-3 Shown, this hydraulic micro-oscillation strengthens sugarcane juice neutralization reaction device is a tubular container 1 whose two ends are horn-shaped tubes 11, 13 and the middle is a round tube 12. The cross-sectional area of ​​the round tube is the same as that of the two ends The cross-sectional area of ​​the small end of the shaped pipe is consistent, the ratio of the cross-sectional area of ​​the small end of the trumpet-shaped pipes 11 and 13 at both ends to the cross-sectional area of ​​the large end is 0.1 to 0.3, and the diameter of the cross-sectional area of ​​the large end of the trumpet-shaped pipes at both ends is equal or not, Figure 2-1 to Figure 2-3 Flared pipe bands at both ends are equipped with flanges 14.

Embodiment 3

[0045] Embodiment 3: One end is a trumpet-shaped tube, the other end is a cylindrical tube, and the middle is a small circular tube connected to form a hydraulic micro-oscillation enhanced sugarcane juice neutralization reaction device.

[0046] Such as Figure 3-1 to Figure 3-3 As shown, the hydraulic micro-oscillation enhanced cane juice neutralization reaction device is a tube-shaped container 2 with a trumpet-shaped tube 21 at one end, a cylindrical tube 23 at the other end, and a small round tube 22 in the middle. The cross-section of the large end of the shaped pipe 21 is approximately equal to the cross-section of the cylindrical pipe 23, the ratio of the cross-sectional area of ​​the small end of the trumpet-shaped pipe 21 to the cross-sectional area of ​​the large end is 0.1~0.3, and the cross-section of the small round pipe 22 Corresponds to the cross-section of the small end of the flared tube.

Abstract

The invention relates to a method for reinforcing cane juice neutralization reaction by hydraulic micro-oscillation, which is applicable to a clarification technique of cane juice or liquid glucose by a sulfurous process. The method comprises the steps of preliming, primary heating, stoving neutralization, hydraulic micro-oscillation reinforced cane juice neutralization reaction, secondary heating and settling. The hydraulic micro-oscillation reinforced cane juice neutralization reaction is implemented in a way that: the cane juice or neutralized juice subjected to stoving neutralization reaction is pumped into a hydraulic micro-oscillation reinforced cane juice neutralization reaction device to subjected to hydraulic micro-oscillation reinforced cane juice neutralization reaction, and enters the steps of secondary heating and settling. The hydraulic micro-oscillation reinforced cane juice neutralization reaction device for implementing the method can change the size of the flow section of the cane juice or liquid glucose in the flowing process: the device is a cylindrical container or tubular container with inconsistent cross-sectional area. The method and device provided by the invention can reinforce the cane juice neutralization reaction, and enhance the purity of the clear juice by more than 1%; and the consumption of lime and sulfur is reduced by more than 20%.

Description

technical field [0001] The invention relates to a sugar making process method and device, in particular to a method and device for clarifying cane juice or sugar liquid in the sugar making process. Background technique [0002] Cane juice (sugar juice) clarification is a key link in the sugar production process. The clarification effect of cane juice (sugar juice) is related to product quality, sugar recovery rate and the amount of clarifying agent, and ultimately affects the competitiveness of sugar factories. At present, the sulfurous method clarification process commonly used in sugar factories, by adding SO 2 , lime milk and phosphoric acid, forming calcium sulfite precipitation and calcium phosphate precipitation to remove the colloid and pigment in the sugar juice, so SO 2 and Ca(OH) 2 The neutralization reaction speed and reaction degree in cane juice (sugar juice) will directly affect the clarification and decolorization effect of the mixed juice and the SO in the ...
