Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a detection device and method for trace amounts of sugar. Background technique [0002] In the sugar production process, the steam generated by the boiler is used to evaporate the water in the sugarcane juice. In order to save energy, the steam evaporated from the sugarcane juice needs to continue to evaporate the water in other sugarcane juices. These are used again The steam from the sugarcane juice that evaporates water is condensed to form condensed water, which is required to be sent to the boiler to continue to generate steam, because the steam from the sugarcane juice will contain a small amount of sugar, when the sugar If the condensed water exceeding the standard enters the boiler, it may cause a production stoppage accident, or cause a serious safety accident. Therefore, it is necessary to detect the sugar content of the condensed water that will be sent ...

Therefore, the accuracy of manual measurement is low

It takes about 10-20 minutes to measure the sugar content of condensed water manually, and it needs to be measured every 20-30 minutes, and its measurement accuracy can only reach 30%-50%. The evaporation rate is calculated at 60-90 tons per hour. When manual measurement finds that the sugar content of the condensed water exceeds the standard, more than 5 tons of condensed water has entered the boiler. Therefore, the existing operation method is neither safe nor accurate.

Therefore, in order to ensure the safety of boiler operation, many sugar factories prefer to discharge the condensed water formed by the evaporation of sugarcane juice, but because the amount of condensed water is large and has a certain temperature (more than 50 tons per hour, the temperature is close to 100 degree), this operation also causes the sugar factory to generate a large amount of sewage discharge, and also wastes a large amount of energy
