Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of water quality detection, and particularly to a pipeline-type full-spectrum water quality monitoring device. Background Art
[0002] With the continuous development of spectral technology, optical-based water quality analysis instruments have developed rapidly. Different chemical substances have different absorption intensities for light of different wavelengths, and most substances have corresponding and definite ultraviolet-visible absorption spectra. The absorption spectrum reflects the characteristics of substances, which is the basis for full-spectrum water quality detection, and then qualitative and quantitative analysis can be carried out. Currently, most optical water quality analysis instruments on the market use single wavelength or dual wavelength for measurement. When the pollutants in water are complex, the influence of interfering substances cannot be effectively excluded, and the data results are often unreliable, making the application range of such instruments narrow. The full-spectrum method measures the wavelength range from ultraviolet to visible, and can simultaneously measure multiple parameters, such as nitrate, nitrite, turbidity, chromaticity, COD, etc.
[0003] In industrial production sites, pipeline installation is often required to facilitate cooperation with the assembly line. The flow of the liquid inside the pipeline can reduce the attachment of dirt, and pipeline installation has become a new application scenario for water quality analysis instruments. In full-spectrum water quality collection, key components such as light sources and spectrometers are required. Often, the stability and reliability of spectral data become the key to measurement. Window fouling, temperature drift problems, and attenuation of light sources have always been disturbing factors. The full-spectrum method measures the absorbance in the entire wavelength range from ultraviolet to visible, almost covering all absorption bands of organic substances. In addition to measuring COD, it can also measure factors such as nitrate, nitrite, turbidity, and chromaticity.
[0004] Among them, the existing detection devices can only passively detect water quality, that is, they can only detect water bodies by collecting water bodies. For factors such as temperature drift that affect the water quality detection results, active control is required. Long-term data detection and analysis are needed, which may take years of detection time, or only through the collected water bodies and the active experimental results in the laboratory. Due to the influence of storage temperature environment and time on the static water bodies after collection, there are also relatively large errors in the inspection of water quality.
[0005] Meanwhile, as the diameter of the water supply pipe increases, the water quality mass factors of the fluid medium in the pipe are not evenly distributed. When directly using a spectrometer to detect and monitor the fluid medium in the pipe, the photosensitive sensitivity of the spectrometer will drift. For the medium with the same concentration, the absorption spectrum will drift, and there is also a lack of comprehensive judgment on the relative medium mass (water quality mass factor) on the longitudinal section of the fluid medium. Moreover, the existing pipeline water quality monitoring device adopts a full-spectrum monitoring method, which requires the same emission and reflection probe to project and collect signals in multiple spectral bands in sequence. Under the influence of the superposition of the medium flow rate, that is, the measurement result will shift in the pipeline flow direction, and the accuracy of water quality judgment obtained by this method is relatively low.
[0006] In summary, the existing water body detection methods require water body collection, and the detection error is relatively large over time. The real-time monitoring detection methods lack measures to individually control the factors in the water quality that can affect the detection results, and the detection results are greatly affected by the environment.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] The existing device for full - spectrum water quality detection of pipeline structures can only passively detect water quality, that is, it can only detect water quality by collecting water bodies or making the target water source to be detected pass through a full - spectrum water quality detector. Although certain water quality standard data can be obtained in this way, in the actual application process, due to various factors such as the distribution change of water bodies inside the pipeline temperature and the temperature drift of the detection instrument, there is contingency in the results of full - spectrum water quality detection. Therefore, in the existing full - spectrum water quality monitoring process, there is a lack of active control of factors such as temperature drift that affect the water quality detection results. It is necessary to conduct long - term data detection and analysis, which may take years of detection time, or only through the active experimental results of collecting water bodies and laboratories. Since the collected static water bodies are affected by the storage temperature environment and time, there are also large errors in the water quality inspection.
[0038] Therefore, as Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a pipeline - type full - spectrum water quality monitoring device, including a main tube body 7, a monitoring component 8 axially installed in the main tube body 7, and a chamber sleeve component 9 sleeved on the main tube body;
[0039] Among them, the main pipe body 7 is used to access the pipeline of the water quality to be detected, and both ends of the main pipe body 7 are provided with flange plates for connection; the monitoring component 8 is used to monitor the water quality entering the main pipe body 7; the cavity sleeve component 9 includes a cavity sleeve main body 91 sleeved on the main pipe body 7. One end of the cavity sleeve main body 91 is communicated with the inside of the main pipe body 7 through a slot 92 provided on the main pipe body 7, and a valve component 93 for controlling the opening and closing of the slot 92 is provided at the end of the cavity sleeve main body 91. The other end of the cavity sleeve main body 91 is provided with a connection port 94. The main function of the connection port 94 is to control the target factor of the water body to be detected in the pipeline, eliminate other influencing factors, and realize the addition of chemical reagents for measurement for the determination or conversion measurement of a single target factor into the cavity sleeve main body 91, and then selectively release them.
[0040] Among them, the source of the additive can specifically include a water supply device with a settable temperature, or it can be an additive supply device that locks a single variable of factors such as COD, nitrates and nitrites, and the turbidity and chromaticity of the water body, and other factors affecting the measurement results are eliminated or reacted, and is released into the pipeline through the cavity sleeve component 9 to single-control the content of a certain factor. That is to say. In the specific process of full-spectrum monitoring of pipeline water quality, it can be realized through the cavity sleeve component 9.
[0041] For example, when detecting the COD factor, alcohol additives can be added to the cavity sleeve main body 91 through the connection port 94. The alcohol additives can react with nitrates and nitrites in the water, so as to be eliminated. Then, strong oxidants are added to the cavity sleeve main body 91 through the connection port 94. Since the strong oxidants can also eliminate the excess alcohol in the water and react with COD to measure the influence of the COD factor on the water quality, and it is an index indicating the amount of reducing substances in the water, and the acetic acid produced after the reaction of alcohol and oxidant is a reducing substance.
[0042] When it is necessary to interfere with the water quality in the main pipe body by the influencing factor of temperature, the valve component 93 closes the slot 92 to make the inside of the cavity sleeve main body 91 in a sealed state.
[0043] Specifically, the main pipe body 7 can be connected to the water supply pipeline of the water quality to be detected in a vertical installation manner, and the external water quality monitoring influencing parameter factors in the cavity sleeve main body 91 can enter the main pipe body 7 through the slot 92. Of course, the slot 92 is located on the main pipe body 7 at the inlet end of the monitoring component 8.
[0044] The column pipe body 7 can also be installed on the water supply pipeline by setting a bypass branch in the water supply pipeline of the water quality to be detected, so as to achieve the purpose of not affecting the water flow rate and pressure of the water supply pipeline.
[0045] Furthermore, the monitoring component 8 in the present invention can be an existing water quality spectral monitoring instrument. However, in order to include the outer tube body 1 and the inner sleeve group 2 installed inside the outer tube body 1, the sleeve group 2 includes a mounting bracket 21 and a plurality of inner sleeves 22. The plurality of inner sleeves 22 are coaxially sleeved and fixedly connected to the mounting bracket 21 in sequence. A medium channel 23 is formed between two adjacent inner sleeves 22. A spectral sensing module 3 is provided on the inner wall of the inner sleeve 22, and a reflective sleeve layer 4 is provided on the outer wall surface of the inner sleeve 22. The reflective sleeve layer 4 is used to reflect the light source entering the water body.
[0046] As Figure 1 shown, the left end of the outer tube body 1 is defined as the water inlet of the outer tube body 1, and the right end of the outer tube body 1 is defined as the water outlet of the outer tube body 1. The fluid medium enters the medium channel 23 of the inner sleeve group 22 from the water inlet and then flows out from the water outlet.
[0047] Furthermore, the spectral sensing module 3 in the present invention includes a spectral projection module 31 and a reflection probe module 32. The spectral projection module 3 is used to project a light source into the medium channel 23, and the reflection probe module 32 is used to collect the light source signal reflected by the reflective sleeve layer 4.
[0048] Among them, the spectral projection module 31 is specifically a pulsed xenon lamp, and the emission probe module 32 is specifically a photodiode array and an AD sampling module. By triggering the pulsed xenon lamp to flash within a unit charging time period, the photodiode array is charged, and the AD sampling module is triggered to collect the optical signal absorbed by the fluid medium during the discharge time period.
[0049] It should be further noted that the ends of the plurality of inner sleeves 22 in the present invention are all located on a certain longitudinal section of the outer tube body 1.
[0050] Further preferably, when adding additives, since it takes time for the additives to react with certain factors in the water body, in order to shorten the reaction process (that is, reduce the length of the main tube body), in the present invention, the plurality of inner sleeves 22 are arranged at equal intervals along the axial direction of the outer tube body 1. There are overlapping and non-overlapping parts in the axial direction of the sleeves of two adjacent inner sleeves 22. Then the overlapping part of two adjacent inner sleeves 22 forms a compression channel (that is, between the inner surface of the larger inner sleeve and the outer surface of the smaller inner sleeve). At this time, the sleeving method of the plurality of inner sleeves 22 has little influence on the water flow rate and water pressure.
[0051] Among them, for the specific spectral measurement section of the emission probe module 32, taking 190 - 720 nm as an example, the spectral ranges projected by the spectral projection modules 31 on multiple inner sleeves 22 are overall in a stepped manner, that is, the spectral measurement section is divided step by step. Each emission probe module 32 collects the spectral range of a set section, or the water quality quality factors of each medium channel can be divided (mainly referring to the distribution of water quality quality factors in the medium). Each medium channel mainly collects the spectrum of a specific water quality quality factor.
[0052] Then, there is no intersection between the spectral ranges projected by two adjacent spectral projection modules 31. By using the situation where the spectral ranges projected by two adjacent spectral projection modules 31 intersect, it is possible to analyze the spectral signals collected by the lower reflection probe module 32 to correct the accuracy of the spectral analysis of the water quality quality factors in the previous medium channel.
[0053] The spectral projection module 31 includes multiple projection heads arranged in an equally spaced annular array on the inner wall of the inner sleeve 22, and the projection heads have an acute angle with the axis of the inner sleeve 22. The acute angle exists to enable the spectral projection module 31, the reflection probe module 32, and the reflection sleeve layer 4 to complete the optical path guidance of the light source projected by the spectral projection module 31.
[0054] Furthermore, in order to form a stable medium flow on the optical path between the spectral projection module 31 and the reflection probe module 32 in the present invention, an angle flow storage rack 5 is provided in the medium channel 23. The angle flow storage rack 5 corresponds to the projection heads one by one. In terms of spatial position, the position of the angle flow storage rack 5 is in front of the spectral projection module 31 (biased towards the water inlet position defined by the outer tube body 1), and both ends (top and bottom) of the angle flow storage rack 5 are respectively connected to two adjacent inner sleeves 22. The angle formed by the connection between the angle flow storage rack 5 and the inner sleeve 22 is the same as the acute angle. The purpose is that when water flows into the medium channel 23.
[0055] Furthermore, the angle flow storage rack 5 provided by the present invention includes a curved surface body 51 facing the water inlet of the outer tube body 1. On both sides of the curved surface body 51, there are guiding side plates 52, and the two guiding side plates 52 are parallel to each other. The guiding side plates 52 extend along the axis of the inner sleeve 22.
[0056] Inside the water outlet of the outer tube body 1 far from the inner sleeve 22, there is a flow converging tube 6. The flow converging tube 6 is specifically frustum-shaped. The diameter of one end is the same as the inner diameter of the outer tube body 1. The fluid medium enters from the side with the same diameter as the outer tube body 1 and flows out from the other end (the water outlet of the outer tube body 1). In this way, due to the different diameters at both ends of the outer tube body 1, the fluid medium entering the inner sleeve group 2 will be retarded under the blocking action of the flow converging tube 6, thus ensuring that the medium in the medium channel 23 of the inner sleeve group 2 is in a relatively stable state.
[0057] Further, in order to achieve high measurement accuracy even under the influence of different flow rates, that is, considering the influence of the optical path offset caused by the water flow velocity, the relative position of the reflection probe module 32 at the optical path receiving end can be adaptively adjusted. The inner sleeve 22 of the present invention includes a first pipe body 221 and a second pipe body 222. A connecting ring 223 is provided at the end of the second pipe body 222 close to the first pipe body 221. The thickness of the connecting ring 223 is smaller than that of the second pipe body 222. An engaging groove 224 for the connecting ring 223 is provided at the end of the first pipe body 221. The connecting ring 223 is connected to the engaging groove 224 through a spring 225 sleeved in the engaging groove 224. The reflection probe module 32 is installed on the inner wall of the second pipe body 222.
[0058] Further, a flow resistance raised ring 226 is provided on the inner surface of the second pipe body 222 of the present invention, and the flow resistance raised ring is provided on the side of the reflection probe module 32 close to the water outlet of the second pipe body 222. The purpose of providing the flow resistance raised ring 266 on the second pipe body 222 is to utilize the interaction between the flow resistance raised ring 266 and the fluid medium (mainly to increase friction, but the ratio of the height to the height of the second pipe body 222 needs to be controlled on the premise of not affecting the flow stability of the fluid medium in the second pipe body 222) under the conditions of increasing flow rate and water pressure, to trigger the relative axial movement between the first pipe body 221 and the second pipe body 222, that is, to improve the "sensitivity" of the first pipe body 221 and the second pipe body 222 to the change of the flow rate of the fluid medium, and to perform adaptive adjustment actions.
[0059] Furthermore, it should be noted that in the present invention, in order to maintain the consistency of the overall structure of the inner sleeve 22 when realizing the relative axial movement between the first pipe body 221 and the second pipe body 222, that is, to maintain the stable flow of the medium in the medium channel, an equal-diameter rubber tube 227 is sleeved on the connecting ring 223, which is mainly made of silica gel material with a small surface deformation, and one end of the equal-diameter rubber tube 227 is fixedly connected to the first pipe body 221, and the other end of the equal-diameter rubber tube 227 is fixedly connected to the second pipe body 222.
