Description

Technical Field

[0001] The utility model belongs to the technical field of sugar production, and in particular relates to a data processing device for sugar production. Background Art

[0002] The entire production process of sugar production is mainly divided into four processes: juice extraction, purification, evaporation, sugar boiling and crystallization, and honey separation. In the evaporation process, the evaporation, sugar boiling and heating processes in the evaporator, sugar boiling tank and heater will produce condensed water with a large amount of heat. These condensed waters must be discharged smoothly to ensure the good heat exchange performance of the heat exchanger. These condensed waters are usually at a high temperature and can recover a large amount of heat. They can generate steam through self-evaporation and can also be used as a heat source for some heaters.

[0003] High-quality condensate can be used as boiler feed water, thus saving part of the cost of softened water and saving energy consumption for heating boilers. At present, the main source of boiler feed water is high-quality condensate and softened water obtained from the evaporation system. However, to be used as feed water for boilers and heat supply, condensate must be of high quality to meet the requirements. Because condensate is evaporated from sugarcane juice in various evaporation tanks. Due to the high and low liquid level in the evaporation tank, unstable steam pressure control, leakage of the heating pipe in the tank, etc., the condensate will contain more or less trace amounts of sugar. When condensate is fed to the boiler as feed water, it must meet the water quality standards for feed water. When the trace sugar content is too high, the boiler will continue to accumulate organic sugars and inorganic salts due to the continuous replenishment of condensate with excessive trace sugar content, the boiler's sewage discharge will increase accordingly, and the boiler's thermal efficiency will decrease accordingly. At the same time, after the trace sugar enters the boiler with the condensate, an oxidation reaction will occur to generate organic acids, thereby lowering the pH of the boiler water. In order to maintain a constant pH, more alkaline substances are needed for neutralization, and the generated organic acids will also aggravate the corrosion of the boiler. In addition, after the trace sugar is caramelized, it becomes a carbon compound, flows with the steam, and is deposited in the metal pipe wall, causing harm to the equipment.

[0004] At present, the main methods for detecting the sugar content of condensate water include gas chromatography, liquid chromatography, polarimetry, spectrophotometry, etc. However, the instruments of gas chromatography and liquid chromatography are expensive, the cost is extremely high, and they are only applicable to laboratories. The polarimetry operation is cumbersome and cannot be detected continuously. The spectrophotometry requires the use of more chemical reagents and the detection time is long. Utility Model Content

[0033] like Figure 1-3 As shown, a data processing device for sugar production includes a detection system 1; the detection system 1 includes a data processing module 11, a temperature detection module 12, a medium characteristic detection module 13, a display module 14, and a communication module 15; the temperature detection module 12 and the medium characteristic detection module 13 are respectively connected to a sample container 16 to be tested and the data processing module 11; the display module 14 and the communication module 15 are connected to the data processing module 11; the sample container 16 to be tested is a metal container; the temperature detection module 12 and the medium characteristic module transmit the detection data to the data processing module 11, the data processing module 11 processes the data, and then outputs it to the display module 14 and the communication module 15;

[0034] The dielectric property detection module 13 includes a sine signal generator 131, a voltage detection component 132 and a current detection component 133; the sine signal generator 131 is connected to the sample to be tested in the sample container 16 through an electrode sheet, and the sine signal generator 131 is used to generate a sine signal in the sample to be tested; the sine signal generator 131 is a DDS chip with an output frequency of 1KHz and a crystal frequency of 6.55MHz; the voltage detection component 132 and the current detection component 133 are respectively connected to the sample to be tested and the data processing module 11, and the power input ends of the voltage detection component 132 and the current detection component 133 are provided with an isolation transformer; the voltage detection component 132 and the current detection component 133 detect the voltage and current in the sample to be tested, and transmit the detection data to the data processing module 11.

[0035] The data processing module 11 includes a microprocessor, specifically an STM32F407 microprocessor; the microprocessor processes the voltage and current data detected by the dielectric property detection module 13, calculates the dielectric loss, conductivity and temperature of the sample to be tested through the voltage and current, and finally obtains the sugar content of the sample to be tested.

[0036] The voltage detection component 132 includes a voltage detector 1321, a filter No. 1322, and a signal converter No. 1323. The voltage detector 1321 is connected to the sample to be tested in the sample container 16 through an electrode sheet; the filter No. 1322 is connected to the voltage detector 1321; the signal converter No. 1323 is respectively connected to the filter No. 1322 and the data processing module 11. The voltage detector 1321 detects the voltage signal of the sample to be tested, filters and removes noise through the filter No. 1322, and then converts the voltage signal into digital data through the signal converter No. 1323, and transmits it to the data processing module 11; the voltage detector 1321 is an instrument amplifier, specifically AD602, which samples and amplifies the voltage, and adds an external resistor for gain amplification;

[0037] The voltage detection component 132 includes a current detector 1331, a second filter 1332, and a second signal converter 1333.

[0038] The filter No. 1 1322 and the filter No. 2 1332 are both low-pass filters. When detecting voltage and current, they will be affected by the electronic components themselves and the external environment, resulting in noise in the voltage data. Therefore, a filter is needed to filter out the noise. Since the noise is basically high-frequency noise, a low-pass filter is used to filter out the high-frequency noise.

[0039] The signal converter No. 1 1323 and the signal converter No. 2 1333 are both A / D converters; after the voltage and current are detected, the analog signals of the voltage and current need to be converted into digital signals, so an A / D converter is selected for conversion, specifically a 12-bit ADC chip.

[0040] The temperature detection module 12 includes a temperature sensor; since the temperature of condensed water from different sources is different, and the dielectric loss data and conductivity data detected at different temperatures are also different, it is necessary to measure the temperature data of the condensed water during detection, and use a temperature sensor to measure the sample to be tested.

[0041] The communication module 15 transmits data with other instruments and equipment through serial communication. The communication module 15 enables the detection instrument to transmit, exchange and store data with other instruments and equipment. The serial communication method can be used for data downloading and system debugging, as well as communication with other equipment.

[0042] The display module 14 includes an LCD liquid crystal display for displaying data.

[0043] The working principle of this embodiment is:

[0044] Since pure sucrose is not conductive, pure sugar-containing condensed water can be regarded as a dielectric. The metal container containing the sample to be tested in this application can be equivalent to a capacitor. When the AC signal passes through the sample to be tested, its impedance has a certain corresponding relationship with the dielectric constant of the capacitor, and the dielectric constant is related to the sugar concentration of the condensed water. Therefore, the sugar concentration in the condensed water can be accurately detected based on the relationship between the dielectric loss of the capacitor and the sugar concentration.

[0045] The properties of the dielectric can be expressed by the dielectric constant, which is related to the sugar concentration. When the sugar concentration changes, the dielectric constant changes, and its capacitance value changes accordingly. Therefore, based on the capacitance characteristics, the dielectric loss can be used to detect the sugar concentration in the condensate.

[0046] In the present application, the metal container for the condensed water sample and the detection electrode are equivalent to forming two plates in an equivalent capacitor, and the condensed water is regarded as the dielectric filled between the two plates. When the sinusoidal signal generator sends out a sinusoidal signal, and the condensed water with different sugar contents has different current and voltage values ​​in the circuit. The dielectric loss value, conductivity value, equivalent resistance value and temperature value of the condensed water can be calculated through the detection circuit, and then the microprocessor performs data calculation and processing to finally obtain the corresponding condensed water sugar concentration value.

[0051] The condensed water is sent from the condensed water outlet of the evaporator into the first storage tank 21, and then the solenoid valve is opened to send a certain amount of condensed water from the first storage tank 21 into the sample container 16 to be tested, and the condensed water is tested. After the test is completed, if the sugar content of the condensed water meets the requirements for entering the furnace, the condensed water in the first storage tank 21 is sent to the second storage tank 22, and then sent to the heat exchanger 25 for heating before entering the furnace; if the sugar content of the condensed water does not meet the requirements for entering the furnace, the condensed water in the first storage tank 21 is sent to the third storage tank 23, and then sent from the third storage tank 23 to the reverse osmosis filter for sugar removal.
