Description

Technical Field

[0001] The utility model relates to the field of online ammonia water detection, in particular to a full-automatic online real-time analysis system for ammonia water. Background Technique

[0002] To prevent excessive NOx generated after coal combustion in industrial boilers from polluting the environment, it is necessary to carry out denitrification treatment on the flue gas discharged from the boilers. As a mature and effective air pollution control technology, SCR (Selective Catalytic Reduction) denitrification technology has been widely applied in industrial sites such as cement plants, steel plants, and power plants. SCR is the selective catalytic reduction technology, and the catalytic reducing agent used is ammonia (NH3). In industry, most ammonia water is used as the ammonia source. Therefore, the analysis and detection of ammonia water concentration are crucial control indicators in the production process. At present, most industrial and mining enterprises adopt the method of manual acid-base titration detection: during the ammonia unloading process of ammonia water, some small samples in the ammonia water tank truck are manually collected and sent to the laboratory. Using the principle of acid-base titration reaction, by the neutralization reaction between ammonia water and hydrochloric acid or sulfuric acid, and through the amount of acid consumed in the titration during the neutralization reaction, the concentration of ammonia water is calculated. However, this method has many disadvantages: a. Time delay: Offline detection requires collecting and transporting the ammonia water sample to the laboratory for analysis, which takes a certain amount of time, resulting in a delay in the detection results and inability to obtain real-time data in a timely manner. b. High cost: Offline detection requires special laboratory equipment and personnel for analysis, with high equipment and labor costs, increasing the operating costs of enterprises. c. Low credibility of analysis data: Due to the time delay of offline detection, the concentration change of ammonia water cannot be continuously monitored, and most enterprises only take an instantaneous sample during the ammonia unloading process, which cannot comprehensively understand the real-time change situation of ammonia water concentration. d. High risk: Offline detection requires transporting the ammonia water sample, there are risks such as sample leakage and pollution. Ammonia water belongs to the second-level hazardous chemical, which is irritating and corrosive to the eyes, nose, and skin of people, and may cause harm to personnel and the environment. e. Large manual error, and the operation level of analysts is likely to have a greater impact on the results. Content of the Utility Model

[0003] The utility model discloses a full-automatic online real-time analysis system for ammonia water, which solves the problems of lagging detection of concentration data, high detection cost, leakage risk, and large detection error in the existing ammonia water concentration analysis system.

The analysis module has a first end, a second end and a third end. The sampling unit is connected to the first end of the analysis module, the cleaning unit is connected to the second end of the analysis module, the intake valve group is connected to the third end of the analysis module. The sample - retaining unit and the liquid - discharging unit are respectively connected between the sampling unit and the first end of the analysis module by three - way pipe fittings. The electric control unit is located on the first end, the second end and the third end of the analysis module, and is used to control the on - off of the first end, the second end and the third end.

[0005] In this application, real - time sampling is carried out through the sampling unit and the sample - retaining unit during the ammonia unloading process. A part of the sampled ammonia water is retained in the sampling unit, and the remaining part enters the analysis module for concentration detection, avoiding the lag of ammonia water concentration data caused by the delay of manual sampling and eliminating the risks existing in manual sampling. After the analysis module completes the detection, the ammonia water can be discharged through the liquid - discharging unit, and the analysis module is cleaned by the cleaning unit and the auxiliary cleaning of the intake valve group is used to discharge the liquid, which is beneficial to improving the accuracy of the next detection.

[0006] The following also provides several optional ways, but it is not an additional limitation to the above overall solution, but only a further supplement or optimization. Without technical or logical contradictions, each optional way can be combined with the above overall solution alone, or multiple optional ways can be combined with each other.

[0007] Optionally, the analysis module includes an analysis chamber, an analysis detection probe, an analysis flowmeter, an analysis inlet electric control valve, an analysis outlet electric control valve, and an analysis outlet check valve. The analysis detection probe is located in the analysis chamber.

The setting of the cleaning unit ensures the removal of residual ammonia water after the test is completed;

[0019] 3. Continuous real-time detection. Through continuous sampling of the sampling unit, the samples pumped into the ammonia tank at each moment are sent to the analysis module for detection, ensuring the real-time and accuracy of the analysis and eliminating the data inconsistency problem caused by intermittent sampling measurement;

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] refer to Figure 1 and Figure 2 In one embodiment of the present application, a fully automatic online real-time analysis system for aqueous ammonia is disclosed, including a sampling unit, a sample retention unit, an analysis module, a cleaning unit, a drainage unit, an intake valve group, and an electronic control unit.

[0035] Among them, the analysis module has a first end, a second end, and a third end, corresponding to the inlet and outlet of ammonia water; the inlet and outlet of the cleaning unit; the inlet and outlet of the intake valve group, and cooperate with the electronic control unit for control.

[0036] Further, the sampling unit is connected to the first end of the analysis module, and is used to extract ammonia water in the ammonia unloading pipeline and transport it to the analysis module and the sample retention unit.

[0037] In some embodiments, the sample retention unit and the liquid discharge unit are respectively connected to the sampling unit and the first end of the analysis module by three-way pipe fittings.

[0038] Further, the cleaning unit is connected to the second end of the analysis module, and is used to extract clean water to wash the analysis module, eliminate the residual ammonia water, and ensure the detection accuracy.

[0039] Further, the intake valve group is connected to the third end of the analysis module, and is used to assist in draining the moisture in the analysis module after cleaning by the cleaning unit.

[0040] Reference Figure 2 , in some embodiments, the analysis module includes an analysis chamber 11, an analysis detection probe 12, an analysis flowmeter 13, an analysis inlet electronic control valve 14, an analysis outlet electronic control valve 15, and an analysis outlet check valve 16.

[0041] Among them, the analysis detection probe 12 is located in the analysis chamber 11 to detect the concentration of ammonia water in the analysis chamber 11. The analysis detection probe 12 can be one of a refractive index concentration probe, a tuning fork resonance concentration probe, or a spectral concentration probe.

[0042] In some embodiments, the analysis detection probe 12 is a refractive index concentration probe.

[0043] In some embodiments, the analysis chamber 11 can adopt a pipeline type or spherical type cavity. For the convenience of discharging ammonia water and the cleaned wastewater, the first ends corresponding to the sample retention unit and the liquid discharge unit on the analysis chamber 11 are located below the analysis chamber 11, and the third end corresponding to the intake valve group is located above the analysis chamber 11.

[0044] It can be understood that the ammonia water in the ammonia unloading pipeline is extracted by the sampling unit and enters the analysis chamber 11 from below the analysis chamber 11, and the air in the analysis chamber 11 is discharged through the third end above the analysis chamber 11. With the assistance of gravity, the cleaned wastewater is discharged through the liquid discharge unit.

[0045] It should be particularly noted that when the analysis chamber 11 adopts a pipeline type cavity, the analysis chamber 11 is arranged vertically, that is, one end of the pipeline type cavity is upward and the other end is downward, which is conducive to the full discharge of ammonia water and the cleaned wastewater in the analysis chamber 11. Different from when the pipeline type cavity is placed horizontally, it is easy to have liquid residue in the analysis chamber 11, affecting the accuracy of subsequent detection.

[0046] Combined with the above embodiments, in another embodiment of the present application, the present application includes a detection state and a cleaning state. In the detection state: the sampling unit extracts ammonia water in the ammonia unloading pipeline and enters from the first end of the analysis module, and then returns to the ammonia unloading pipeline from the third section to form a complete loop to achieve the purpose of real-time detection; in the cleaning state: the cleaning unit injects clean water from the second end of the analysis module to clean the analysis module, and the wastewater after cleaning is assisted by the intake valve group connected to the third end of the analysis module and discharged from the first end of the analysis module through the drainage unit.

[0048] The analysis outlet electronic control valve 15 and the analysis outlet check valve 16 are connected to the analysis chamber 11 corresponding to the third end of the analysis module, and are used to control the ammonia water to be discharged from the analysis chamber 11 and return to the ammonia unloading pipeline.

[0049] In an embodiment of the present application, the cleaning unit includes a cleaning spray head 21, a cleaning electronic control valve 22, a cleaning flowmeter 23, a cleaning pump 24, and a cleaning filter 25 connected in sequence. External clean water is introduced by the cleaning filter 25, and after being pressurized by the cleaning pump 24, it is sprayed by the cleaning spray head 21.

[0050] Among them, the cleaning flowmeter 23 can enable the user to directly see the flow rate of the clean water in the cleaning unit, and the cleaning electronic control valve 22 can be automatically turned on and off through the electronic control unit.

[0051] To achieve a better cleaning effect, the cleaning spray head 21 is connected to and extends into the analysis chamber 11, and can directly flush the analysis detection probe 12.

[0052] Among them, the cleaning spray head 21 can be one of a conical, square, fan-shaped, or columnar flow spray head.

[0053] To ensure the cleaning effect, the cleaning spray head 21 is a columnar flow spray head.

[0054] In an embodiment of the present application, the sampling unit includes a sampling pre-filter 31, a sampling pump 32, and a sampling post-filter 33 connected in sequence. The sampling pre-filter 31 is connected to the external ammonia unloading pipeline, and the sampling post-filter 33 is connected to the sampling unit and the first end of the analysis module through a tee pipe fitting.

[0055] In the above embodiments, the sampling pump 32 can be one of a centrifugal pump, a diaphragm pump, and a magnetic pump.

[0056] In some embodiments, the sampling pump 32 is a centrifugal pump.

[0057] In the above embodiments, the sampling pre-filter 31 can be one of a mesh filter, a cartridge filter, and a disc filter.

[0058] In some embodiments, the sampling pre-filter 31 is a mesh filter.

[0059] In the above embodiments, the sampling post-filter 33 can be one of a mesh filter, a cartridge filter, and a disc filter.

[0060] In some embodiments, the sampling post-filter 33 is a cartridge filter.

[0061] In an embodiment of the present application, the sample retention unit includes a sample retention electromagnetic valve 41, a sample retention regulating valve 42, and a sample retention bottle 43 arranged in sequence. The sample retention electromagnetic valve 41 is controlled by an electronic control unit for opening and closing.

[0062] In an embodiment of the present application, the liquid discharge unit includes a liquid discharge electromagnetic valve 51, a liquid discharge check valve 52, and a liquid discharge pump 53 arranged in sequence. The liquid discharge electromagnetic valve 51 is connected to the analysis inlet electromagnetic valve 14 through a tee pipe fitting to the analysis chamber 11. The opening and closing of the liquid discharge electromagnetic valve 51 is controlled by the electronic control unit, and the liquid discharge pump 53 is controlled to start to form a negative pressure to extract the clean waste water in the analysis chamber 11.

[0063] In an embodiment of the present application, the intake valve group includes an intake electromagnetic valve 61, an intake check valve 62, and an intake filter 63 connected in sequence. The intake electromagnetic valve 61 is connected to the analysis outlet electromagnetic valve 15 through a tee pipe fitting to the analysis chamber 11, and the intake filter 63 is connected to the outside atmosphere.

[0064] It should be noted that in the present application, the pre-filter 31 of the sampling unit is connected to the ammonia unloading pipeline for extracting ammonia water from the ammonia unloading pipeline; the analysis outlet check valve 16 of the analysis module is connected to the ammonia unloading pipeline for returning the ammonia water after the detection is completed; the liquid discharge pump 53 of the liquid discharge unit is connected to the ammonia unloading pipeline for discharging the cleaned waste water into the ammonia unloading pipeline.

[0065] In an embodiment, the working steps of an automatic full-line real-time ammonia water analysis system in the present application are disclosed as follows:

[0066] 1. System self-check before detection; when the system receives an ammonia unloading request or a DCS signal, the self-check mode is started. If a component is abnormal, the system alarms and reports the relevant alarm signal to the DCS through the display controller. After the system self-check is normal, the system automatically enters the next control program.

[0067] 2. Pre-detection cleaning process: The system closes the sampling pump 32, the sample retention electromagnetic control valve 42, the analysis inlet electromagnetic control valve 14, the analysis outlet electromagnetic control valve 15, the air inlet electromagnetic control valve 61, the liquid discharge electromagnetic control valve 51, and the liquid discharge pump 53. The cleaning electromagnetic control valve 22 and the cleaning pump 24 are opened. Clear water enters the cleaning pump 24 through the cleaning filter 25, and is sprayed from the cleaning nozzle 24 to the analysis and detection probe 12 through the cleaning electromagnetic control valve 22, completing the cleaning of the analysis and detection probe 12. The cleaning duration can be preset in the display controller;

[0068] 3. Post-cleaning liquid discharge process: After the cleaning process is completed, the system closes the sampling pump 32, the sample retention electromagnetic control valve 41, the analysis inlet electromagnetic control valve 14, the analysis outlet electromagnetic control valve 15, the cleaning electromagnetic control valve 22, and the cleaning pump 24. The air inlet electromagnetic control valve 61, the liquid discharge electromagnetic control valve 51, and the liquid discharge pump 53 are opened. The cleaned liquid is discharged by the liquid discharge pump 53 through the liquid discharge electromagnetic control valve 51 and the liquid discharge check valve 52 to the ammonia unloading pipeline, completing the discharge of the cleaning liquid. The liquid discharge duration can be preset in the display controller;

[0069] 4. Sampling and analysis process during detection: The system closes the air inlet electromagnetic control valve 61, the liquid discharge electromagnetic control valve 51, the liquid discharge pump 53, the cleaning electromagnetic control valve 22, and the cleaning pump 24. The sampling pump 24, the analysis inlet electromagnetic control valve 14, and the analysis outlet electromagnetic control valve 15 are opened. The ammonia water liquid to be detected is transported by the sampling pump 24 through the sampling pre-filter 31 and the sampling post-filter 33 to the analysis module, and flows back to the ammonia unloading pipeline through the analysis inlet electromagnetic control valve 14, the analysis flowmeter 13, the analysis chamber 11, the analysis and detection probe 12, the analysis outlet electromagnetic control valve 15, and the analysis outlet check valve 16 of the analysis module. When the ammonia water to be detected flows through the analysis chamber 11, the analysis and detection probe 12 analyzes the ammonia water to be detected in real time and outputs relevant data to the display controller, and the display controller completes data storage, uploading, and display;

[0070] 5. Sample retention process during detection: While step "4" is being carried out, the system determines whether to make a sample retention request according to the preset parameters in the display controller and the detection results, and can perform abnormal sample retention or full-process sample retention according to the preset requirements. When sample retention is required, the system automatically opens the sample retention electromagnetic control valve 41, and the ammonia water to be sampled flows through the sample retention electromagnetic control valve 41 and the sample retention regulating valve 42 to the sample retention bottle 43 and is stored in the sample retention bottle 43;

[0071] 6. Post-detection cleaning process: Repeat steps "2" and "3".

[0072] In some embodiments, the above display controller and the electronic control unit in the present application are of an integrated structure.

[0073] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are embodied in the same drawing, the drawing can be regarded as also disclosing the combined examples of the various embodiments involved.

[0074] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
