Description

Technical Field

[0001] The utility model relates to the field of sugar-making equipment, in particular to a novel evaporation system for raw sugar production. Background Art

[0002] Within 8 days after the full-through washing of the evaporation pan, the steam pressure of the first-effect steam drum of the evaporation pan is normally within the range of 0.16 - 0.19 Mpa, the syrup Brix reaches the index range of 69 - 73 Bx, and the steam consumption per ton of sugar is about 1.898; after 8 days of through washing, the steam pressure of the first-effect steam drum of the evaporation pan needs to be adjusted to 0.2 - 0.22 Mpa, the syrup Brix drops to 63 - 66 Bx, which fails to meet the standard, and the steam consumption per ton of sugar is about 2.0475, with an increase in steam consumption. Therefore, the evaporation pan needs to be washed in rotation within 8 days to exert its normal evaporation efficiency. When the squeezing capacity is higher than 12000 T / D, in order to ensure that the evaporation syrup Brix meets the process requirements, the current evaporation system pipeline cannot meet the requirement of stopping the evaporation pan for through washing without reducing the squeezing capacity, and can only stop the pan for through washing when the supply of raw sugarcane is small or the squeezing capacity of sugarcane is forced to be reduced. During the actual production in the squeezing season, the washing frequency is basically once every 30 - 35 days, and the time required to completely wash 8 pans is about 8 days. Moreover, during the 8-day washing time, the squeezing capacity must be lower than 12000 tons, which seriously affects the improvement of the squeezing capacity, and the washing frequency of the evaporation pan is much lower than the normal daily washing frequency.

[0003] If the existing evaporation system needs to be washed in rotation, the daily squeezing capacity must be reduced to below 12000 T to carry out. After reducing the squeezing capacity, it is very unfavorable to the steam balance of the whole factory, and the supplementary steam system needs to be started, resulting in more steam consumption. Moreover, the serious fouling caused by the inability to wash the evaporation system in rotation normally requires reducing the pressing infiltration water to 12% (normal is 15%) and the suction filtration and water injection volume to 3% (normal is 5 - 6%) to maintain the sugarcane pressing capacity. Therefore, improving the existing evaporation system to enable the evaporation system to wash 1 evaporation pan per day while maintaining the production capacity and the evaporation syrup Brix, without reducing the pressing infiltration water and the water injection volume of the suction filter, and reducing the filter mud transmittance can improve the sugar recovery.
