催化燃烧法处理?VOCs?的全过程中,给出几类安全风险:活性炭过滤—吸附—催化燃烧法中有活性炭着火的状况、催化反应炉发生爆炸难题、全部催化燃烧整治设备着火发生爆炸难题。
In the whole process of treating VOCs by catalytic combustion method, several kinds of safety risks are given: activated carbon ignition in activated carbon filtration adsorption catalytic combustion method, explosion of catalytic reaction furnace, and explosion of all catalytic combustion treatment equipment.
1.活性炭着火状况及预防措施在早期的?VOCs?含有全过程中,?因为活性碳着火点较低而吸附溫度过高,当对吸咐饱和状态的活性碳开展吸附处理时,会因为吸附箱身体溫度过高造成活性碳起火。处理该难题能够从2个层面下手:一要选用着火点高的活性碳;二是严控吸附溫度,使其远远低于活性碳着火点。因而可采用给出对策:严控吸附溫度,挑选性价比高的吸附温度感应器,尽量在活性炭过滤箱适合部位安裝2个温度感应器;在?PLC?程序编写中添加吸附溫度过热时终止吸附程序流程;一起要防范于未然,在活性炭过滤箱上边提升消防安全自来水管并相互连接烟尘警报及全自动自喷设备,防止出现意外起火。
1. Ignition status and preventive measures of activated carbon in the whole process of early VOCs containing, the adsorption temperature is too high due to the low ignition point of activated carbon. When adsorption treatment is carried out on the saturated activated carbon, the activated carbon will catch fire due to the high temperature of the adsorption box. To solve this problem, we can start from two aspects: one is to select activated carbon with high ignition point; the other is to strictly control the adsorption temperature to make it far lower than the ignition point of activated carbon. Therefore, the following countermeasures can be taken: strictly control the adsorption temperature, select the adsorption temperature sensor with high cost performance, try to install two temperature sensors in the suitable part of the activated carbon filter box; add the adsorption temperature in the "PLC" programming, and terminate the adsorption process when the adsorption temperature is too hot; take precautions together, lift the fire safety water pipe above the activated carbon filter box and connect the smoke alarm Alarm and automatic spraying equipment to prevent accidental fire.

2.催化反应炉发生爆炸难题及预防措施在处理高浓?VOCs?时,因为炉内带有很多co2,当有机废气浓度值超过有机废气双组分中绝大多数工业废气的爆炸极,就会有发生爆炸的风险。?因而,要時刻检测炉内?VOCs?浓度值,?在进到催化反应炉的废气管道边安裝浓度值稀释液设备,将高浓有机废气稀释液到爆炸极限下。?一起在催化反应炉上提升工作压力自动排气阀,在工作压力过高时全自动开启闸阀开展缓解压力排气管,防止炉内溫度工作压力过高造成发生爆炸(因有机废气在热氧化全过程中快速释放出来很多能源造成炉内火气体压力过大)。
2. Problems and preventive measures of explosion in catalytic reaction furnace when dealing with high concentration VOCs, because there is a lot of CO2 in the furnace, when the concentration of organic waste gas exceeds the explosion limit of most industrial waste gas in organic waste gas, there will be the risk of explosion. Therefore, it is necessary to detect the concentration of VOCs in the furnace at all times, and install the concentration diluent equipment beside the waste gas pipe into the catalytic reaction furnace, so as to reduce the high concentration organic waste gas diluent to the explosion limit. ? raise the working pressure of the automatic exhaust valve on the catalytic reaction furnace together, and open the gate valve automatically when the working pressure is too high to release the pressure exhaust pipe, so as to prevent the explosion caused by too high temperature and working pressure in the furnace (the fire gas pressure in the furnace is too high due to the rapid release of a lot of energy in the whole process of thermal oxidation).
3.全部催化燃烧整治设备着火发生爆炸及预防措施全部催化燃烧整治设备着火发生爆炸多产生在只能一整套吸咐设备的系统软件中,因管路壁及机器设备内集聚很多高浓工业废气细颗粒物,管路电动风阀闭会空隙过大,在吸附催化燃烧全过程中沒有终止生产制造,?生产车间旁通阀不可以关掉,全部管道是全通的,这时吸附催化燃烧极将会在高溫功效下造成全部系统软件着火发生爆炸。?对于上述所说情况应当采用给出对策:安裝高品质电动风阀,常常查验漏汽状况,单套吸咐的设备系统软件中在吸附催化燃烧全过程中应停工处理等。
3. Fire and explosion of all catalytic combustion treatment equipment and preventive measures the fire and explosion of all catalytic combustion treatment equipment mostly occurred in the system software of only one set of adsorption equipment. Due to the accumulation of a lot of high concentration industrial waste gas fine particles in the pipeline wall and mechanical equipment, the gap between the electric air valves in the pipeline was too large, and the production and manufacturing were not terminated in the whole process of adsorption catalytic combustion,? The by-pass valve of the production workshop can not be closed, and all pipelines are fully connected. At this time, the adsorption catalytic combustion pole will cause all system software to catch fire and explode under the high temperature effect. ? for the above situation, the countermeasures should be given: installing high-quality electric air valve, often checking the steam leakage condition, stopping work in the whole process of adsorption catalytic combustion in a single set of adsorption equipment system software, etc.
