Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalytic combustion equipment technology, specifically a monitoring device for catalytic combustion equipment. Background Technology
[0002] Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in waste gas at relatively low temperatures, typically within the temperature range of 300℃ to 450℃. Compared to traditional thermal combustion methods, catalytic combustion requires less auxiliary fuel, consumes less energy, and requires relatively smaller equipment, thus it has been widely used in the field of industrial waste gas treatment.
[0003] However, current catalytic combustion equipment on the market has certain limitations in its design, especially in terms of external structure. Many existing devices lack effective monitoring and protection mechanisms to monitor the equipment's operation in real time, which not only affects combustion efficiency but may also lead to safety hazards. For example, without effective differential pressure monitoring, it is difficult to detect and resolve problems caused by pressure imbalances in a timely manner, thus affecting combustion efficiency and compliance with emission standards. In addition, there is insufficient real-time monitoring of smoke particles and temperature changes generated during combustion, making it impossible to provide timely warnings of potential safety risks, such as incomplete combustion or overheating.
[0004] In view of the above problems, existing catalytic combustion equipment urgently needs a monitoring device that can integrate multiple sensors (such as differential pressure sensors, smoke sensors, and temperature sensors) and monitor the internal operating status of the equipment in real time. Such a device should not only have data acquisition capabilities but also intelligent analysis capabilities to automatically adjust operating parameters and optimize combustion conditions based on the collected data. Simultaneously, it should quickly issue alarm signals when an anomaly is detected, thereby improving the safety and reliability of the entire device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5As shown, this utility model provides a technical solution: a monitoring device for a catalytic combustion device, used to monitor the catalytic combustion device 1. The catalytic combustion device 1 has a blower 102 at its bottom. The monitoring device includes a differential pressure sensor 2 installed in the catalytic combustion device 1, positioned near the air inlet of the catalytic combustion device 1. The differential pressure sensor is fixed to a preset hole in the catalytic combustion device with bolts to ensure accurate measurement of the pressure difference inside and outside the catalytic combustion device, thereby evaluating combustion efficiency. A smoke sensor 3 and a temperature sensor 4 are installed in the exhaust pipe 101 of the catalytic combustion device 1. These two sensors should be installed on the inner wall of the exhaust pipe 101 of the catalytic combustion device 1, using a flange connection to ensure the sensors are stable and well-sealed. The smoke sensor 3 is used to detect smoke particles produced by incomplete combustion, while the temperature sensor 4 monitors temperature changes during the combustion process to ensure the safety and efficiency of the combustion process. The monitoring box 5 of the catalytic combustion device is located on the outside of the catalytic combustion device for easy operation and observation. The monitoring box 5 integrates a controller 6, a power supply 7, and a signal transmitter 8, and is securely fixed to the wall using expansion screws via a wall-mounted installation method. A display screen 9 is located on one side of the monitoring box, displaying all collected data for operator viewing. Simultaneously, the signal transmitter 8 can wirelessly transmit this data to a remote monitoring center for real-time monitoring. An alarm light 10 is fixedly connected to the top to display data and issue warnings in real time. A differential pressure sensor 2 is installed inside the catalytic combustion device 1, enabling the device to monitor the internal pressure difference. When the pressure difference is large, the controller 6 can control the blower 102 to increase its operating power, quickly eliminating the pressure difference and providing early warning of potential problems. Real-time monitoring and analysis of the pressure difference effectively improves the overall performance of the equipment, extends its service life, and ensures emissions meet standards. A smoke sensor 3 and a temperature sensor 4 can detect the specific conditions inside the catalytic combustion device 1, improving the safety of equipment operation.
[0033] Please refer to the following carefully. Figure 3 A guide post 501 is fixedly connected to one side of the monitoring box 5. A heat insulation layer 502 is sleeved on the guide post 501. An iron sheet layer 503 is also provided on one side of the heat insulation layer 502. An installation hole 504 is opened inside the iron sheet layer 503. A magnet 505 is fixedly connected inside the installation hole 504. An installation hole 5031 adapted to the guide post 501 is opened on the iron sheet layer 503. A heat insulation layer 502 made of high temperature resistant aluminum silicate material is sleeved on the guide post 501. The iron sheet layer 503 is wrapped around the outside of the heat insulation layer and fixed in the installation hole 504 by the magnet 505 to enhance the heat insulation effect and facilitate disassembly and maintenance.
[0034] Please refer to the following carefully. Figure 2 and Figure 3The controller 6 is electrically connected to the alarm light 10, the display screen 9, the signal transmitter 8, and the air supply fan 102. The output terminals of the differential pressure sensor 2, the smoke sensor 3, the temperature sensor 4, and the power supply 7 are all connected to the input terminal of the controller 6. When the catalytic combustion equipment is running, the differential pressure sensor 2, the smoke sensor 3, and the temperature sensor 4 start to work, respectively collecting parameters such as the pressure difference, smoke concentration, and temperature inside the catalytic combustion equipment, and transmitting these data to the controller 6.
[0035] The controller 6 in this application is a PLC controller. The temperature sensor is model PT100, the smoke sensor is model MQ-2, and the differential pressure sensor 2 is model 1MPP2-2. All sensors are designed to be waterproof and dustproof to adapt to industrial environments. The cables of the differential pressure sensor 2, smoke sensor 3, and temperature sensor 4 are neatly routed through a dedicated cable tray, ensuring both safety and aesthetics. After receiving data from each sensor, the controller 6 (PLC controller) analyzes the data according to preset safety parameter thresholds. If any abnormality is detected (such as excessive pressure difference, excessive smoke concentration, or temperature exceeding the safe range), the controller will immediately take measures, such as adjusting the speed of the blower 102 to optimize combustion conditions (for example, increasing the speed of the blower 102 to optimize combustion conditions when the internal pressure of the catalytic combustion device 1 is too high), or activating the alarm light 10 and sending an alarm signal to the remote monitoring center. This device includes a differential pressure sensor, a smoke sensor, a temperature sensor, and its matching control unit, which can monitor various states of the catalytic combustion device 1, realizing comprehensive monitoring of the operating status of the catalytic combustion device, improving the safety and working efficiency of the equipment, and also facilitating maintenance and management.
[0036] Working Principle: A differential pressure sensor 2 is installed inside the catalytic combustion device 1, enabling it to monitor the internal pressure difference. When the detected pressure difference exceeds a set threshold, the controller 6 controls the blower 102 to increase its operating power, thereby accelerating airflow within the catalytic combustion device 1 and quickly eliminating the current pressure difference. Similarly, when the smoke concentration measured by the smoke sensor 3 is high, the controller 6 also increases the speed of the blower 102, accelerating airflow within the catalytic combustion device 1 and quickly expelling the smoke. Similarly, when the temperature measured by the temperature sensor 4 is high, the controller 6 also increases the speed of the blower 102, accelerating airflow within the catalytic combustion device 1 and facilitating rapid temperature reduction. This structure effectively improves the overall performance of the catalytic combustion device, extends its service life, and ensures emissions meet standards. The smoke sensor 3 and temperature sensor 4 allow for monitoring of the internal conditions of the catalytic combustion device 1, enhancing the safety of its operation.
[0037] It is worth noting that when using this invention, the working status of each sensor needs to be checked regularly to ensure that they are not affected by dust or other contaminants. Cleaning or replacement may be necessary. For the monitoring box 5, the working status of its internal components should be checked regularly, especially the controller 6 and power supply 7, to ensure the stable operation of the entire system. If you encounter problems that cannot be resolved or the system malfunctions, you can obtain assistance by consulting the log files or contacting technical support.
