Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water quality monitoring equipment, and particularly relates to an online siliconate monitor. BACKGROUND

[0002] As a core device for industrial water quality monitoring, the online siliconate monitor is widely used in the fields of electric power, chemical industry, metallurgy, etc. By detecting the siliconate ion concentration in water samples in real time, the online siliconate monitor provides key data support for the risk assessment and process optimization of the scaling of boiler water, circulating cooling water and ultrapure water systems. The core working principle of the online siliconate monitor relies on the accurate mixing, reaction and transmission of reagents and water samples in the pipeline system. The cleanliness of the pipeline system directly affects the accuracy of the color reaction and the reliability of the detection results. However, in the long-term continuous operation process, the inner wall of the pipeline for conveying reagents and water samples inevitably leaves pollutants, which becomes a key factor restricting the detection accuracy and stability of the instrument.

[0003] At present, the main challenge faced by the pipeline system of the online siliconate monitor is that when conveying reagents containing color developing agents and masking agents and complex water quality (such as water samples containing suspended solids and colloidal silicon) for a long time, the inner wall of the pipeline is easy to adsorb and precipitate silicon scale, metal ion complexes or organic impurities, which causes the residual substances to mix into the new sample in the subsequent test, resulting in deviation of the detection results (such as false positive or concentration drift). In the prior art, the cleaning and maintenance of the inner wall of the pipeline generally adopts the manual disassembly, soaking and brushing method. This method not only needs to interrupt the monitoring process, but also consumes a lot of manpower and time cost. In addition, frequent disassembly may cause the pipeline joints to loosen and the sealing ring to age, increasing the risk of liquid leakage. Furthermore, for the online monitoring equipment with high integration degree, some pipelines are arranged compactly and have large bending degree, so that manual cleaning cannot completely remove the residues in the dead angle, further affecting the long-term operation accuracy of the instrument.

[0004] In summary, the pipeline cleaning technology of the existing online siliconate monitor has obvious defects: the manual disassembly and cleaning method is tedious and inefficient, and cannot meet the needs of continuous operation and intelligent maintenance of the equipment in the industrial field; and the lack of design of automatic cleaning mechanism causes the residual pollutants to become an important source of detection errors. Therefore, it is urgent to invent a technical solution that can automatically and efficiently clean the inner wall of the reagent and water sample conveying pipeline without disassembling the pipeline, so as to solve the problems of tedious maintenance and detection accuracy easily affected in the prior art, and improve the reliability and practicality of the online siliconate monitor.

[0047] Here, the target water source refers to a water source that can provide a water sample, which can be boiler water, chemical and petroleum industry process water, industrial wastewater, etc.

[0048] Further, at least one of the plurality of liquid storage bottles 14 is used to store a water quality sample of the target water source, and the output end of the water sample delivery pump 16 is connected to the liquid storage bottle 14 through a pipeline.

In this embodiment, the number of liquid storage bottles 14, three-way electromagnetic valves I 22 and three-way electromagnetic valves II 23 is preferably even.

Alternatively, the pipeline can be adjusted adaptively to ensure that the flushing assembly 30 and the plurality of liquid supply paths form a cleaning path in series. The specific adjustment method can be implemented according to actual conditions, and will not be described further here.

[0049] Specifically, the cabinet 10 is rotatably connected to a hatch on one side, and the hatch is fixed to a touch screen control module near one side of the cabinet 10.

The micro-sample water pump 21 is started to deliver the reagents and water samples in the multiple liquid storage bottles 14 to the inside of the reaction bottle 15 through the multiple micro-sample water pumps 21. After the water sample and the reagent react, the concentration of silicate is determined and converted by the light source analysis module 19. When it is necessary to clean the reagent and water sample remaining on the inner wall of the liquid supply hose 24, the three-way electromagnetic valve I 22 and the three-way electromagnetic valve II 23 are started to change from the working state to the cleaning state. The flushing assembly 30 and the multiple liquid supply paths form a cleaning path in a series manner. The flushing assembly 30 is operated to drive the dynamic cleaning assembly 40 to move reciprocally in the liquid supply hose 24 through the flushing assembly 30. The inner wall of the liquid supply hose 24 is cleaned by the dynamic cleaning assembly 40. The device can clean the inner wall of the liquid supply hose 24 without disassembling the liquid supply hose 24, which avoids the influence of the reagent and water sample remaining on the inner wall of the liquid supply hose 24 on the subsequent monitoring results and improves the cleaning efficiency of the inner wall of the liquid supply hose 24 and the accuracy of the water sample monitoring results.

[0052] Secondly, please refer again to Figures 2 to 5The flushing assembly 30 comprises a liquid storage box 31 and a cleaning water pump 32. The liquid storage box 31 is fixed in the first storage cavity 11, and first and second circulation openings are respectively formed at two ends of the liquid storage box 31. The cleaning water pump 32 is fixed in the detection cavity 13. A first hose 33 is assembled between the first circulation opening and an input end of the cleaning water pump 32. A second hose 34 is fixed between a three-way electromagnetic valve I 22 closest to the cleaning water pump 32 and an output end of the cleaning water pump 32.
