[0027] In a boiler water quality detection device of this embodiment, the first delivery pipe 20 and the second delivery pipe 21 are both made of transparent materials. Optionally, the first delivery pipe 20 and the second delivery pipe 21 can be transparent tubes made of glass.

[0028] In a boiler water quality detection device of this embodiment, the driver 2 is a peristaltic pump.

[0029] In a boiler water quality detection device of this embodiment, a filter screen 15 is provided at the connection between the first delivery pipe 20 and the second delivery pipe 21. The filter screen 15 is used to filter impurities in the boiler water to reduce the influence of the impurities on the spectral detection process.

[0030] In a boiler water quality detection device of this embodiment, the heat transfer medium 1 is heat transfer oil, and the first delivery pipe 20 in the constant temperature chamber 18 is located in the heat transfer oil. The first delivery pipe 20 has a large contact area with the heat transfer medium 1, and the boiler water temperature in the first delivery pipe 20 is adjusted quickly.

The heat absorbed by the cooling plate 6 is dissipated through the radiator 4 and the fan 5, so that the temperature of the heat-conducting medium 1 is reduced, thereby reducing the temperature of the boiler water.

[0035] In a boiler water quality detection device of this embodiment, a temperature sensor 3 is arranged in the constant temperature chamber 18. The temperature sensor 3 is arranged and connected to the controller 10 or an external control room, so that an operator can judge the temperature in the constant temperature chamber 18 conveniently.

The first grating 8 and the ultraviolet receiving array 9 are respectively located on opposite sides of the first position on the second delivery pipe 21, and the ultraviolet light source 7 and the first position on the second delivery pipe 21 are respectively located on opposite sides of the first grating 8; the second grating 13 and the infrared receiving array 14 are respectively located on opposite sides of the second position on the second delivery pipe 21, and the infrared light source 12 and the second position on the second delivery pipe 21 are respectively located on opposite sides of the second grating 13.

[0039] Water quality spectral analysis uses light sources, receiving arrays, gratings and other equipment to analyze water quality components, turbidity, chromaticity and other characteristics. The working principle is as follows: the light emitted by the ultraviolet light source 7 passes through the first grating 8 and then shines on the second conveying tube 21, and the light reaches the ultraviolet receiving array 9 after passing through the second conveying tube 21; the light emitted by the infrared light source 12 passes through the second grating 13 and then shines on the second conveying tube 21, and the light reaches the infrared receiving array 14 after passing through the second conveying tube 21. The light source usually uses white light or light of a specific wavelength, which will be absorbed, scattered or transmitted after passing through the sample. The receiving array is a multi-channel photodetector that can detect light signals of multiple wavelengths at the same time. The output of the receiving array will generate corresponding spectral data based on the absorption, scattering or transmission. The grating disperses light of different wavelengths into different angles through the principles of diffraction and interference, thereby forming a spectral image. The receiving array will capture these dispersed light signals.

[0040] By using the light source, receiving array and grating, the absorption, scattering or transmission of light of different wavelengths by the sample can be obtained, and then the composition, turbidity and color characteristics of the sample can be analyzed. The above components are usually used together with a spectrometer. By measuring the optical response of the sample at different wavelengths, detailed spectral information can be obtained, thereby performing water quality analysis and monitoring.

The wireless transmission technology can use a 4G network.

[0042] In a boiler water quality detection device of this embodiment, a valve is installed at the outlet end of the second delivery pipe 21 to control the on-off of the second delivery pipe 21. Optionally, the valve can be a solenoid valve 11, which is connected to the controller 10 to realize automatic control.

[0043] The specific working process of the device is as follows: when the temperature sensor 3 detects that the temperature of the heat transfer oil in the constant temperature chamber 18 is lower than 120 degrees Celsius, it is heated by the heating rod 16, and when it is higher than 120 degrees Celsius, it is cooled by the refrigeration plate 6, and the constant temperature is controlled at 120 degrees Celsius. The temperature is relatively easy to control, and the peristaltic pump draws the boiler water into the first delivery pipe 20. The boiler water in the first delivery pipe 20 is sent to the second delivery pipe 21 through the filter 15 after the temperature is adjusted in the constant temperature chamber 18. In the spectrum detection chamber 19, the metal ions in the water are detected by the cooperation of the ultraviolet light source 7, the first grating 8 and the ultraviolet receiving array 9, and the acid substances in the water are detected by the cooperation of the infrared light source 12, the second grating 13 and the infrared receiving array 14.
