AI Technical Summary

Problems solved by technology

In the current sugar making system and process, the self-evaporating steam cannot be recovered in time, and the heat energy loss is relatively large; the condensed water in the evaporation tank cannot be removed in time, and the juice vapor escapes more, which cannot be recycled according to the quality of the condensed water. Self-evaporating steam generated by condensed water cannot be recovered

Abstract

The invention discloses a thermal system and a technology for evaporation, heating and sugar boiling in sugar preparation. In an evaporation system, juice gas pipes of evaporation tanks 1#-6# are communicated with each other. The juice gas pipes between the evaporation tanks are connected to tail ejectors. Juice vapor in the evaporation tank IV enters into a juice vapor valve of the evaporation tank V. Through an assistant water ring vacuum pump and the ejectors, heat of spontaneous steam and discharged incondensable gas produced by syrup production in the evaporation tank V is directly pumped and used for primary heating of the mixed juice. The thermal system and the technology have the advantages that secondary vapor fed from the evaporation tank at the tail into a condenser is reduced and even avoided; heat loss is reduced maximumly; condensate water in the evaporation tanks is discharged timely; secondary steam unloading is avoided; condensate water can be recovered according to quality; and spontaneous vapor produced from vapor condensate is recovered as much as possible.

Description

technical field [0001] The present invention relates to the technical field of sugar production, in particular to a thermal system and process for evaporating, heating and boiling sugar in the sugar industry. Background technique [0002] The energy consumption of sugar mills depends on the selection of evaporative thermal scheme, and the advantages and disadvantages of thermal scheme mainly lie in the rational use of evaporating tank juice and condensate for good removal and low-grade thermal energy recovery. In the current sugar making system and process, the self-evaporating steam cannot be recovered in time, and the heat energy loss is relatively large; the condensed water in the evaporation tank cannot be removed in time, and the juice vapor escapes a lot, so it cannot be recycled according to the quality of the condensed water. The self-evaporating steam produced by the steam condensate cannot be recovered either. SUMMARY OF THE INVENTION [0003] The technical prob...
