Icro-sugar online measuring system and measuring method thereof

Abstract

The invention discloses a micro-sugar online measuring system and a measuring method thereof. The online measuring system includes a pretreatment device, a photoelectric detection module and a single-chip microcomputer control module. The output end of the pretreatment device is connected to the photoelectric detection module, the output end of which is connected to the single-chip microcomputer control module. The pretreatment device comprises a mixer, a heater and a first cooler that are connected in order. The outlet of the first cooler is connected to the input end of the photoelectric detection module. The heater is a lightwave infrared heater. The system and the method provided in the invention utilizes a photoelectric detecting technique to conduct micro-sugar content online measurement, the measuring accuracy is high, and at the same time, the lightwave infrared heater is employed to heat a mixed solution of steam condensate and ammonium molybdate, the heating efficiency is high, temperature rise is very fast, and the mixed solution of steam condensate and ammonium molybdate can be heated to a reaction temperature within several seconds to tens of seconds, so that the measurement time is greatly shortened, continuous monitoring of the sugar content in the steam condensate can be guaranteed, and potential safety hazards of production can be solved.

Description

technical field [0001] The invention relates to the field of detection of sucrose content, in particular to an on-line micro-sugar content measurement system and a measurement method thereof. Background technique [0002] In the sugar evaporation section of the sugar factory, the water in the sucrose solution will be evaporated. In order to save energy, the evaporated steam is often recycled and condensed to form condensed water, which is introduced into the boiler and heated to generate steam to drive the turbine generator. Power generation is supplied to sugar factory equipment, and then the tail gas of power generation is used to evaporate the water in the sucrose solution, or the steam source required for other production in the sugar factory, so as to achieve the purpose of recycling, energy saving and emission reduction. However, these reused steam, because they are evaporated from the sucrose solution, contain a certain amount of sugar, if the sugar content exceeds th...
