Catalytic combustion equipment, as a key device for treating organic waste gases, is widely used in many industries such as chemical engineering, painting, and printing. Proper use of this equipment can not only ensure that exhaust gas treatment meets standards, but also ensure stable operation of the equipment, extend its service life, and reduce operating costs. Below is a detailed introduction to the usage methods and key points of catalytic combustion equipment from multiple aspects.

一、设备启动前准备

1、 Preparation before device startup

全面检查：在启动设备前，需要对设备进行全面细致的检查。查看设备外观是否有损坏，各连接部件是否牢固，管道有无破裂、泄漏等情况。重点检查催化剂床层，确保催化剂无结块、破损或流失现象，若发现催化剂有问题，应及时处理或更换，因为催化剂的性能直接影响设备的处理效率。

Comprehensive inspection: Before starting the equipment, it is necessary to conduct a comprehensive and detailed inspection of the equipment. Check whether the appearance of the device is damaged, whether the connecting components are firm, and whether the pipelines are cracked, leaking, etc. Focus on inspecting the catalyst bed to ensure that there is no agglomeration, damage, or loss of catalyst. If any problems are found with the catalyst, they should be dealt with or replaced in a timely manner, as the performance of the catalyst directly affects the processing efficiency of the equipment.

电气系统检测：对设备的电气系统进行严格检测，包括配电箱内的电器元件是否正常，线路连接是否正确，有无短路、断路隐患。检查各仪表、传感器是否能正常工作，如温度传感器、压力传感器等，这些仪表能实时反馈设备运行状态，对安全运行至关重要。此外，还需确认接地保护是否可靠，防止触电事故发生。

Electrical system inspection: Strictly inspect the electrical system of the equipment, including whether the electrical components in the distribution box are normal, whether the circuit connections are correct, and whether there are any hidden dangers of short circuits or open circuits. Check if all instruments and sensors are working properly, such as temperature sensors, pressure sensors, etc. These instruments can provide real-time feedback on the equipment's operating status, which is crucial for safe operation. In addition, it is necessary to confirm whether the grounding protection is reliable to prevent electric shock accidents.

通风与气体置换：开启设备的通风系统，对设备内部及管道进行充分通风换气，将可能残留的可燃气体或其他有害气体排出。通风时间应根据设备和管道的容积大小合理确定，一般不少于 15 分钟，确保设备内部环境安全。通风结束后，可使用惰性气体（如氮气）对设备进行置换，进一步降低可燃气体浓度，避免点火时发生爆炸危险。

Ventilation and gas replacement: Turn on the ventilation system of the equipment, fully ventilate the interior and pipelines of the equipment, and discharge any residual flammable or other harmful gases. The ventilation time should be reasonably determined according to the volume size of the equipment and pipelines, generally not less than 15 minutes, to ensure the safety of the internal environment of the equipment. After ventilation is completed, inert gas (such as nitrogen) can be used to replace the equipment, further reducing the concentration of combustible gases and avoiding the risk of explosion during ignition.

二、设备运行操作要点

2、 Key points for equipment operation

升温与点火：启动设备的加热系统，缓慢对废气进行预热，升温速率应控制在合适范围内，一般建议不超过 5℃/min。过快升温可能导致设备部件热胀冷缩不均匀，造成损坏。当废气温度达到催化剂的起燃温度（通常在 200 - 300℃之间，具体数值因催化剂种类而异）时，启动点火装置。点火过程中，密切观察火焰情况，确保点火成功。若点火失败，应立即停止燃料供应，再次进行通风置换后，方可重新点火。

Heating and ignition: Start the heating system of the equipment and slowly preheat the exhaust gas. The heating rate should be controlled within an appropriate range, generally not exceeding 5 ℃/min. Excessive heating may cause uneven thermal expansion and contraction of equipment components, resulting in damage. When the exhaust gas temperature reaches the ignition temperature of the catalyst (usually between 200-300 ℃, the specific value varies depending on the type of catalyst), the ignition device is activated. During the ignition process, closely observe the flame situation to ensure successful ignition. If ignition fails, the fuel supply should be immediately stopped and ventilation replacement should be carried out again before re ignition.

运行参数调控：设备运行过程中，需要对多个参数进行实时调控。根据废气的浓度和流量，调节风机的转速，确保废气在设备内有合适的停留时间和流速，一般停留时间控制在 0.5 - 2 秒之间。同时，密切关注催化燃烧反应温度，通过调节燃料供应或引入冷空气等方式，将反应温度维持在设定的工作温度范围内（一般为 300 - 400℃）。若温度过高，可能烧坏催化剂和设备部件；温度过低，则会影响反应效率和净化效果。此外，还需监测设备进出口的压力，确保压力差在正常范围内，若压力差过大，可能意味着设备内部存在堵塞，应及时排查原因。

Operation parameter regulation: During the operation of the equipment, real-time regulation of multiple parameters is required. According to the concentration and flow rate of the exhaust gas, adjust the speed of the fan to ensure that the exhaust gas has a suitable residence time and flow rate inside the equipment. Generally, the residence time is controlled between 0.5-2 seconds. Meanwhile, closely monitor the catalytic combustion reaction temperature and maintain it within the set operating temperature range (usually 300-400 ℃) by adjusting the fuel supply or introducing cold air. If the temperature is too high, it may burn out the catalyst and equipment components; If the temperature is too low, it will affect the reaction efficiency and purification effect. In addition, it is necessary to monitor the pressure at the inlet and outlet of the equipment to ensure that the pressure difference is within the normal range. If the pressure difference is too large, it may indicate that there is a blockage inside the equipment, and the cause should be promptly investigated.

废气成分监测：定期对进入设备的废气成分进行检测，了解废气中有机污染物的种类和浓度变化。如果废气成分发生较大变化，如某些高浓度、难降解的有机物含量增加，可能需要调整设备的运行参数，或者对废气进行预处理，以保证设备的稳定运行和处理效果。例如，当废气中含有较多的含氯有机物时，可能会导致催化剂中毒，此时可在废气进入设备前增加水洗或碱洗等预处理工序，去除含氯物质。

Monitoring of exhaust gas composition: Regularly detect the composition of exhaust gas entering the equipment to understand the types and concentration changes of organic pollutants in the exhaust gas. If there is a significant change in the composition of the exhaust gas, such as an increase in the content of certain high concentration and difficult to degrade organic compounds, it may be necessary to adjust the operating parameters of the equipment or pre treat the exhaust gas to ensure the stable operation and treatment effect of the equipment. For example, when the exhaust gas contains a high amount of chlorinated organic compounds, it may cause catalyst poisoning. In this case, pre-treatment processes such as water washing or alkali washing can be added before the exhaust gas enters the equipment to remove chlorinated substances.

三、设备日常维护

3、 Daily maintenance of equipment

催化剂维护：催化剂是催化燃烧设备的核心部件，其性能直接关系到设备的处理效果。定期对催化剂进行检查和维护，一般每运行 1 - 2 个月，对催化剂进行一次外观检查，查看是否有积碳、烧结等现象。每隔半年至一年，对催化剂的活性进行检测，若活性下降明显，可根据情况进行再生处理。对于失活严重的催化剂，应及时更换。催化剂再生方法有热再生、化学再生等，可根据催化剂的种类和失活原因选择合适的方法。

Catalyst maintenance: Catalysts are the core components of catalytic combustion equipment, and their performance directly affects the treatment effect of the equipment. Regularly inspect and maintain the catalyst, usually every 1-2 months of operation, conduct a visual inspection of the catalyst to check for carbon deposition, sintering, and other phenomena. Every six months to one year, the activity of the catalyst should be tested. If the activity decreases significantly, regeneration treatment can be carried out according to the situation. For catalysts with severe deactivation, they should be replaced in a timely manner. The catalyst regeneration methods include thermal regeneration, chemical regeneration, etc., and the appropriate method can be selected according to the type of catalyst and the reason for deactivation.

设备清洁：定期对设备内部和外部进行清洁，去除表面的灰尘、油污和其他杂质。特别是对设备的进气口、出气口、管道等部位，要定期清理，防止积尘和杂物堵塞，影响气流分布和设备运行。设备内部的换热器、燃烧室等部件，也应定期进行清洗，保证其换热效率和燃烧效果。清洁时，可使用压缩空气、清洁剂等工具，注意避免对设备部件造成损坏。

Equipment cleaning: Regularly clean the interior and exterior of the equipment to remove dust, oil stains, and other impurities from the surface. Especially for the air inlet, outlet, pipeline and other parts of the equipment, they should be cleaned regularly to prevent dust accumulation and debris blockage, which will affect the airflow distribution and equipment operation. The internal heat exchangers, combustion chambers, and other components of the equipment should also be regularly cleaned to ensure their heat transfer efficiency and combustion effectiveness. When cleaning, compressed air, cleaning agents, and other tools can be used to avoid damaging equipment components.

易损件更换：设备运行过程中，一些易损件会逐渐磨损或老化，需要定期更换。如风机的皮带、轴承，点火装置的火花塞，阀门的密封件等。根据设备的使用情况和厂家建议，制定易损件的更换计划，及时更换磨损的部件，确保设备的正常运行。同时，在更换易损件时，要选择质量可靠的产品，保证其与设备的兼容性和匹配性。

Replacement of vulnerable parts: During the operation of the equipment, some vulnerable parts will gradually wear or age and need to be replaced regularly. Such as belts and bearings of fans, spark plugs of ignition devices, seals of valves, etc. Based on the usage of the equipment and the manufacturer's recommendations, develop a replacement plan for vulnerable parts, promptly replace worn parts, and ensure the normal operation of the equipment. At the same time, when replacing vulnerable parts, reliable products should be selected to ensure their compatibility and compatibility with the equipment.
