Description
技术领域technical field
本发明涉及尾气、废气的净化系统，尤其涉及一种VOCs尾气吸附—催化燃烧处理系统。The invention relates to a tail gas and waste gas purification system, in particular to a VOCs tail gas adsorption-catalytic combustion treatment system.
背景技术Background technique
表面涂装、印刷、印染、煤矿瓦斯抽放、垃圾填埋场的垃圾填埋气排放等工业过程中均会产生和排放大量含VOCs的尾气，这类尾气具有排风量大、尾气中VOCs浓度低、对环境造成污染、有害人体健康的特点，其危害不容忽视。传统的有机废气净化方法有吸附法、吸收法、冷凝法等，此类方法的共同特点是对尾气中的VOCs进行富集和回收，但这些方法存在处理效率低、易产生二次污染、受有机物种类限制的缺点。而催化燃烧技术能够将这类尾气在催化剂的作用下转化为无害的二氧化碳和水等物质，同时放出热量。但是在催化燃烧过程中需要将废气加热达到催化剂的最佳使用温度，而由于这类尾气中可燃的VOCs浓度低，燃烧所放出的热量不足以维持催化燃烧的进行，因此，需要消耗大量额外的能源。Industrial processes such as surface coating, printing, printing and dyeing, coal mine gas drainage, and landfill gas discharge from landfills will generate and discharge a large amount of exhaust gas containing VOCs. The characteristics of low concentration, pollution to the environment, and harmful to human health cannot be ignored. Traditional organic waste gas purification methods include adsorption method, absorption method, condensation method, etc. The common feature of these methods is the enrichment and recovery of VOCs in the tail gas, but these methods have low treatment efficiency, are prone to secondary pollution, and are subject to The disadvantage of limited species of organic matter. The catalytic combustion technology can convert this kind of exhaust gas into harmless carbon dioxide and water under the action of a catalyst, and release heat at the same time. However, in the process of catalytic combustion, it is necessary to heat the exhaust gas to the optimum temperature of the catalyst, and because the concentration of combustible VOCs in this type of exhaust gas is low, the heat released by combustion is not enough to maintain the progress of catalytic combustion, so a large amount of additional energy is required energy.

The solenoid valve 12 is opened at the same time, and the high-temperature airflow drawn from the high-temperature gas port in the middle of the catalytic burner 5 enters the adsorption tower 3 for desorption-regeneration process. After the low-concentration VOCs waste gas is combined, it enters the flow direction conversion catalytic combustion device for catalytic combustion, and generates carbon dioxide and water, which are then discharged harmlessly through the induced draft fan 6 .
上述实施例中，吸附塔的数量可根据实际需要多于两个，如三个、四个等，并交替进行吸附和脱附—再生过程。In the above embodiments, the number of adsorption towers can be more than two according to actual needs, such as three, four, etc., and the adsorption and desorption-regeneration processes are performed alternately.
上述实施例中，流向变换催化燃烧装置的使用方法为：进气阀16和排气阀17为一组并同步开关，进气阀18和排气阀19为一组并同步开关，控制两组进、排气阀交替使用，达到控制VOCs尾气在催化燃烧器5内周期性切换流动方向，使VOCs尾气在催化燃烧器5内往复流动、吸热和放热，实现VOCs尾气的自热催化燃烧,；当该过程达到稳定后，在催化燃烧器5内会形成中间高达400～500℃、两边接近室温的温度分布。In the above-mentioned embodiment, the use method of the flow direction conversion catalytic combustion device is as follows: the intake valve 16 and the exhaust valve 17 form a group and switch synchronously, the intake valve 18 and the exhaust valve 19 form a group and switch synchronously, and control the two groups The intake and exhaust valves are used alternately to control the VOCs tail gas to periodically switch the flow direction in the catalytic burner 5, so that the VOCs tail gas reciprocates, absorbs and releases heat in the catalytic burner 5, and realizes the self-heating catalytic combustion of the VOCs tail gas ,; when the process reaches a steady state, a temperature distribution of 400-500°C in the middle and close to room temperature on both sides will be formed in the catalytic burner 5 .
