Description

[0002] With increasingly stringent environmental regulations, flue gas denitrification technology has been widely used in the industrial field. Flue gas denitrification mainly uses technical means such as selective catalytic reduction (SCR) to reduce nitrogen oxides (NOx) produced during combustion to harmless nitrogen (N2) and water (H2O). In order to verify the denitrification effect, it is necessary to analyze the composition of the flue gas after denitrification. However, since the flue gas environment is usually accompanied by high temperature, high dust, high humidity and strong corrosiveness, its sampling and processing process faces the following technical difficulties:

[0003] Insufficient temperature control accuracy: The temperature of the sampling pipeline is difficult to stably control within the set range, which may cause condensation of moisture in the flue gas and form liquid to block the pipeline, thereby affecting the accuracy of the analysis results and the economic operation of the unit.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0052] like Figure 1 FIG. 1 is a schematic diagram of the structure of a flue gas denitration sampling and processing system according to an embodiment of the present disclosure. The system comprises:

[0053] The temperature control module 110 is used to adjust the temperature of the sampling pipeline, including a temperature measurement unit for collecting the temperature signal of the sampling pipeline in real time, a temperature judgment unit for judging the current temperature state based on a set threshold, and a heating control unit for driving the heating belt to adjust the temperature of the sampling pipeline through a solid-state relay;

[0054] The intelligent alarm module 120 is used to warn of abnormal temperature conditions, including a signal input unit for receiving temperature measurement values, an alarm determination unit for comparing the temperature measurement values ​​with the alarm threshold value, and an alarm output unit for sending an alarm to the operator through an audible and visual alarm or a system notification;

[0055] The condensate drainage module 130 is used for discharging condensate, and includes a dual-channel drainage system, which is composed of two independent drainage pipelines, and can realize redundant switching through a connecting pipe, and a peristaltic pump unit, which is used to discharge the condensate out of the system through the drainage pipeline;

[0056] The logic control module 140 is used to adjust the operation strategy according to the signal states of the temperature control module, the intelligent alarm module and the condensation drainage module.

[0057] Specifically, the temperature control module (110) is used to maintain the temperature of the sampling pipeline within a set range to prevent moisture in the flue gas from condensing at low temperatures and causing blockage in the sampling pipeline, while ensuring accurate sampling of flue gas components.

[0058] Specific composition and working method:

[0059] The temperature measurement unit uses a thermal resistor or thermocouple deployed in the sampling pipeline to collect temperature signals in real time to ensure that the temperature data is accurate and timely.

[0060] The temperature judgment unit compares the measured temperature signal with the preset temperature threshold to determine whether the current temperature state meets the requirements. If it is lower than the set threshold, it is judged as low temperature and heating needs to be started.

[0061] The heating control unit precisely controls the on / off status of the heating belt through the solid-state relay. The solid-state relay has the characteristics of high sensitivity and long life. It can respond quickly according to the signal of the temperature judgment unit, dynamically adjust the power of the heating belt, and maintain the stability of the pipeline temperature.

[0062] The intelligent alarm module (120) is used to monitor the temperature state of the sampling pipeline in real time, and to send out an early warning signal when the temperature is abnormal (such as lower than a set value), so as to remind the operating personnel to take timely measures to prevent pipeline blockage or data inaccuracy.

[0063] Specific composition and working method:

[0064] The signal input unit receives the temperature measurement data of the temperature control module and transmits the data to the alarm judgment unit.

[0065] The alarm determination unit compares the temperature measurement value with the preset alarm threshold value to determine whether an alarm is required. For example, when the temperature is lower than the alarm value, an alarm signal is immediately triggered.

[0066] The alarm output unit uses an audible and visual alarm device or a DCS system to send an alarm to the operator, ensuring that the alarm information is quickly conveyed. At the same time, the alarm time and temperature data are recorded for subsequent analysis and maintenance.

[0067] The condensate drainage module (130) solves the problem of continuity of flue gas condensate discharge, adopts a dual-channel design, and is equipped with an automatic switching function to ensure that the system can still operate normally even if one drainage pipeline is blocked.

[0068] Specific composition and working method:

[0069] The condenser cools the water vapor in the flue gas and condenses it into liquid, ensuring that the water is separated from the flue gas during the sampling process.

[0070] The two independent drainage pipelines of the dual-channel drainage system are each equipped with a check valve and a drainage monitoring device to detect the drainage status in real time. Once an abnormal flow in one channel is detected, the electric switching valve of the connecting pipe automatically switches to the backup channel.

[0071] The peristaltic pump unit uses a rotor to squeeze the drain hose to form a stable flow rate, discharge the condensate out of the system, and avoid pipe blockage and backflow.

[0072] The logic control module (140) is the core of the entire system and is responsible for coordinating the signal interaction between the temperature control module, the intelligent alarm module and the condensation drainage module, and improving the system efficiency by dynamically adjusting the operation strategy.

[0073] Specific composition and working method:

[0074] The logic operation unit collects real-time signals from all modules (such as temperature data, alarm signals, and drainage status) and determines whether the current system is in a normal state through logic operations. If an abnormality occurs, the corresponding processing is triggered immediately.

[0075] The dynamic strategy adjustment unit dynamically assigns priorities according to system operating conditions. For example, in an alarm state, it will prioritize starting heating or switching drainage channels, and restore the original strategy after the temperature returns to normal, ensuring coordinated operation of each module.

[0076] Beneficial effects: The temperature control module achieves precise adjustment of the sampling pipeline temperature through dynamic heating, avoiding condensation and pipeline blockage caused by low temperature; the intelligent alarm module monitors temperature abnormalities in real time, and promptly reminds operators through sound and light alarms or system notifications, improving the system's emergency response capabilities; the dual-channel design and automatic switching function of the condensation drainage module ensure the continuity of the drainage system, and even if a certain channel fails, it will not affect the normal operation of the system; the logic control module realizes efficient linkage of each sub-module, dynamically optimizes system performance through flexible operation strategies, and improves the intelligence and reliability of the denitrification sampling process.

[0077] like Figure 2 FIG. 1 is a flow chart of a flue gas denitrification sampling and processing method according to an embodiment of the present disclosure, comprising:

[0078] S201: collecting a pipeline temperature signal through a temperature measurement unit, and triggering a heating control unit to heat the sampling pipeline based on a threshold judgment result of a temperature judgment unit to maintain the temperature within a set range;

[0079] S202: Based on the real-time temperature monitoring, the measured value is compared with the preset alarm threshold, and when the temperature is lower than the threshold, an alarm signal is generated and notified to the operator through the alarm output unit;

[0080] S203: The flue gas is condensed by a condenser, and the condensed liquid is discharged through a dual-channel drainage system. When one channel is blocked, it is switched to a backup drainage pipeline;

[0081] S204: Adjusting the operation strategy of each module according to the temperature control, abnormal alarm and condensation drainage signal.

[0082] Specifically, S201: collecting the pipeline temperature signal through the temperature measurement unit, triggering the heating control unit to heat the sampling pipeline based on the threshold judgment result of the temperature judgment unit to maintain the temperature within the set range.

[0083] The denitrification flue gas sampling pipeline needs to be maintained within a specific temperature range to prevent moisture in the flue gas from condensing due to low temperature and causing blockage in the sampling pipeline. If the temperature is lower than the set value, it will directly affect the subsequent sampling accuracy and even the feasibility of sampling.

[0084] Implementation:

[0085] The temperature measurement unit collects the temperature data in the pipeline in real time and transmits it to the temperature judgment unit. The temperature judgment unit compares the collected temperature value with the set temperature range (such as the minimum temperature and the maximum temperature). If the temperature is lower than the set value, the temperature judgment unit immediately triggers the heating control unit to control the heating belt to start heating through the solid-state relay. The heating control unit dynamically adjusts the power of the heating belt according to the temperature deviation to ensure that the temperature returns to the set range and remains stable.

[0086] S202: Based on real-time temperature monitoring, the measured value is compared with a preset alarm threshold. When the temperature is lower than the threshold, an alarm signal is generated and the operator is notified through an alarm output unit.

[0087] The flue gas sampling system may fail to control the temperature under certain abnormal conditions, such as a failure of the heating device or a sharp drop in the external ambient temperature. If it is not discovered and handled in time, the pipeline may be blocked by condensation, resulting in sampling failure. Therefore, real-time monitoring and early warning mechanisms are particularly important.

[0088] Implementation:

[0089] The data of the temperature measurement unit and the temperature control module will be synchronously transmitted to the alarm judgment unit. The alarm judgment unit compares the current temperature value with the preset alarm threshold, for example, setting a safety alarm value (such as 5°C below the set temperature). Once the temperature is lower than the threshold, the alarm output unit will trigger an audible and visual alarm or send a notification to the operator terminal through the DCS system. At the same time, the alarm time and temperature value will be recorded for subsequent problem tracking and maintenance decisions.

[0090] S203: The flue gas is condensed through a condenser, and the condensed liquid is discharged through a dual-channel drainage system. When one of the channels is blocked, it is switched to a backup drainage pipeline.

[0091] The smooth discharge of flue gas condensate is crucial to the sampling process. If the drainage pipeline is blocked, the accumulation of condensate may cause system abnormality or even shutdown. Therefore, a dual-path drainage system with redundant design can improve operational reliability.

[0092] Implementation:

[0093] The condenser condenses the water vapor in the flue gas into liquid, which is discharged through a dual-channel drainage system. The drainage channel is equipped with a flow monitoring unit and a check valve to detect the drainage flow status in real time to prevent liquid backflow or blockage. If the flow in one channel is abnormal or completely interrupted, the electric switching valve in the connecting pipe will automatically switch to the backup drainage channel. The peristaltic pump unit ensures the stability of the drainage channel pressure by squeezing the drainage hose and discharges the condensate smoothly out of the system.

[0094] S204: Adjusting the operation strategy of each module according to the temperature control, abnormal alarm and condensation drainage signal.

[0095] The flue gas sampling system needs to dynamically adjust its strategy according to the operating conditions. For example, when the temperature returns to normal, the heating should be stopped; when a drainage channel is restored to normal, the activation of the backup channel can be cancelled. The role of the logic control module is to coordinate the linkage of various modules and optimize the overall performance of the system.

[0096] Implementation:

[0097] The logic control module receives the real-time signal status of the temperature control module, intelligent alarm module and condensation drainage module, and analyzes the overall operation of the system. Through the built-in logic configuration, the priority strategy is set. For example, when the alarm signal is triggered, the heating or drainage path is started first; when the alarm is lifted, the normal mode operation is restored. The logic control module can record the operation status and adjustment history of each module to facilitate subsequent analysis and optimization of system performance.

[0098] Beneficial effects: Through the above steps, this method achieves stable control of flue gas sampling pipeline temperature, abnormal alarm, smooth discharge of condensate and dynamic adjustment of system logic. Compared with traditional technologies, this method significantly improves the reliability and automation of the denitrification sampling and processing system, effectively reduces operational risks, and provides more efficient and accurate support for environmental monitoring.
