Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measurement systems and relates to an online detection device for the concentration of suspended solids in deacidification liquid, and more particularly to an online detection device for measuring the concentration of suspended inorganic solids in an anhydrous liquid-phase organic system. Background Technology
[0002] Existing instruments for measuring suspended solids concentration typically use photoelectric colorimetry. This principle states that when a beam of monochromatic parallel light passes through a colored solution, some of the light energy is absorbed by the solution. If the liquid layer thickness remains constant, the degree of light absorption is directly proportional to the concentration of the colored substance in the solution. However, photoelectric colorimetry can only measure substances with specific absorption wavelengths. For substances without obvious absorption peaks, it cannot be directly used for measurement. Secondly, photoelectric colorimetry is significantly affected by environmental factors such as temperature and humidity. These factors can cause fluctuations in light intensity and degrade the performance of the photodetector, thus affecting the accuracy of the measurement results. Based on the measurement method, instruments are divided into sample-based and online types. Sample-based instruments require a specific container to take the sample and place it into the instrument for testing, which does not meet the requirements for real-time measurement in deacidified suspensions. Online measuring instruments are mostly immersion-based, meaning the probe is immersed in the test liquid, and the measurement signal is transmitted back to the host for calculation and display. The optical detection of suspended matter uses the underwater scattering method. The detection of the concentration of suspended matter in the deacidification suspension is based on the transmittance of light by the suspended particles. This requires a portion of the light source probe to be immersed in the deacidification suspension. In order to achieve stable and accurate measurement, the measuring probe should be at a vertical angle to avoid the excitation light affecting the fluorescent photodetector. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of existing technologies by providing an online detection device for the concentration of suspended solids in deacidification liquid. This device addresses the real-time changes in the concentration of deacidified substances in the deacidification suspension when inorganic deacidified substances migrate to paper in an anhydrous fluorocarbon solvent system, and also solves the efficiency problem of deacidified substance migration to paper. This invention employs a scattering method by emitting a laser beam into the water body. When the light beam intersects with the suspended solid particles, scattering occurs. By measuring the scattering angle and scattering intensity, the concentration of suspended solid particles can be determined.

[0005] A device for detecting the concentration of suspended solids in a deacidification solution, and an online device for detecting the concentration of suspended solids in a deacidification solution, is characterized by comprising a deacidification paper clamp 1, an air jet device 2, a portable suspended solids measuring instrument 3, a probe 4, and a glass container 5; wherein the portable suspended solids measuring instrument 3 is embedded in the center of the front of the glass container 5 and is connected to the probe 4, which is placed inside the glass container 5, via a cable; the deacidification paper clamp 1 and the air jet device 2 are respectively located on the front left side of the bottom of the glass container 4, and a drain valve 6 is also located on the rear right side of the bottom of the glass container 5. The clamp fixes the deacidification paper, and the air jet device allows the paper to unfold and be fully immersed in the deacidification suspension; the portable suspended solids measuring instrument is connected to the probe via a cable.
[0006] The portable suspended matter measuring instrument 3 described above, preferably the Hach TSS Portable portable suspended matter measuring instrument, stores multiple different suspended matter calibration curves. For different applications, there is no need for constant recalibration.
[0007] The portable suspended matter measuring instrument 3 described above measures the concentration of inorganic suspended matter in organic solvents using a multi-beam alternating light method with dual-channel 90-degree scattered light through an infrared diode system.
[0008] The preferred glass container 5 is a cuboid and has no lid.
[0009] The probe 4 described above is made of polished stainless steel, which can be used in harsh environments and helps to avoid experimental errors caused by particulate matter adhering to the probe surface.
[0010] The aforementioned probe 4 includes an infrared probe, wherein the infrared receiving probe is a probe with a wavelength of 860nm.
[0011] Compared with the prior art, the beneficial effects of the technical solution of this utility model are:
[0012] This invention uses a scattering method to measure the concentration of deacidified liquid, solving the problem that organic solvents can affect the measurement of inorganic suspended matter concentration. It also reduces measurement errors caused by paper spreading in the deacidified suspension and particulate matter adhering to the probe surface. Furthermore, the instrument stores multiple different suspended matter calibration curves, making the measurement results more accurate. Attached Figure Description

[0015] Example 1
[0016] like Figure 1 As shown, an online detection device for suspended solids concentration in deacidification liquid consists of a deacidification paper clamp (1), an air jet device (2), a portable suspended solids measuring instrument (3), a probe (4), and a glass container (5). The portable suspended solids measuring instrument (3) is embedded in the center of the front of the glass container (5) and is connected to the probe (4) placed inside the glass container (5) via a cable. The deacidification paper clamp (1) and the air jet device (2) are respectively provided on the front left side of the bottom of the glass container, and a drain valve (6) is provided on the rear right side of the bottom of the glass container (5).
[0017] Example 2
[0018] The apparatus in this embodiment is the same as in embodiment 1. The required deacidified paper clamp 1 is clamped at the bottom of the glass box to ensure that the paper does not fall off. After the magnesium oxide-containing all-fluoroheptane deacidification suspension is introduced into the glass container 5, the jet device 2 is turned on so that the paper is fully immersed in the deacidification suspension while it is fixed by the deacidified paper 1. The light source probe (made of polished stainless steel) must be completely immersed in the organic phase deacidification suspension. The concentration change of magnesium oxide suspended matter in the all-fluoroheptane deacidification suspension is measured by the Hach TSS Portable suspended matter measuring instrument 3 embedded in the center of the front of the glass frame 5. After the measurement is completed, the jet device 2 is turned off and the remaining deacidification suspension is discharged through the drain valve 6.
[0019] The device was used to measure the deacidification effect of a Qing Dynasty book. The original concentration of the deacidified suspension was 3 g / L, and the concentration after deacidification was 1.7 g / L. The concentration after deacidification was further verified to be 1.62 g / L by filtration and weighing. The device is quite accurate in detecting the concentration of suspended solids after deacidification.
