废气处理设备对高浓度废气的初步处理?

来源:http://www.spormac.net/   发布时间:2018-07-09 16:34:59
工业中要用到废气处理设备,首要就是对工业中一些高浓度废气进行处理,这样可以防止废气处理体系发生爆破事故,也有一些注意事项,焊烟除尘器的小编就解说这些,期望能对您有所协助.
To use the waste gas treatment equipment in industry, the first is to deal with some high concentration waste gas in the industry, which can prevent the explosion accident of the waste gas treatment system, and also have some notices. The small editor of the welding smoke dust collector will explain these and expect to help you.
工业中要对高浓度废气进行预处理,下降排入废气处理体系的可燃物浓度,如对反应釜废气排放口设冷却或冷冻收回设备,或活性碳纤维吸附收回设备;制止高于爆破下限的可燃蒸汽和可燃气体排入废气管道体系。在废气体系规划前,要对各废气吸入点的可燃物浓度进行检测剖析,操控各废气吸入点的易燃物质的浓度低于爆破下限,并要进行正常作业状况或非正常作业状况下的可燃气体浓度检测。
In industry, high concentration waste gas should be pretreated to decrease the concentration of combustibles in the waste gas treatment system, such as the cooling or cryopreservation equipment of the exhaust gas discharge port of the reactor, or the adsorption and recovery of the activated carbon fiber, and combustible steam and combustible gas which is higher than the lower limit of blasting to be discharged into the exhaust pipe system. Before the planning of the exhaust system, the concentration of the combustibles should be detected and analyzed. The concentration of flammable substances for the control of the exhaust gas suction points is lower than the lower limit of the blasting, and the normal operation condition or the concentration of combustible gas under the abnormal operation condition should be carried out.

当某废气吸入点各种工况可能吸入的可燃物浓度超越安全浓度时,要改动工艺或设备,如弥补新风或进行慵懒化处理。对可能会发生废气浓度挨近爆破下限的废气支管道设置在线可燃气体浓度检测报警器和新风弥补设备,在线可燃气体浓度检测报警器应和新风弥补设备联锁。反应釜应尽可能选用密闭式,防止有空气(氧气)进入反应釜和废气管道,下降高浓度废气中氧气含量,当然能慵懒化(如充氮)更好。焊烟除尘器
When the concentration of the combustibles that may be inhaled in various operating conditions is beyond the safe concentration, the process or equipment should be changed, such as the new wind or the lazy treatment. The on-line combustible gas concentration detection alarm and new air compensation equipment may be set up for the exhaust gas pipeline which may be near the lower limit of the exhaust gas, and the on-line combustible gas concentration detection alarm should be interlocked with the new wind remedy equipment. The reaction kettle should be used as close as possible to prevent the air (oxygen) entering the reaction kettle and the exhaust pipe, reducing the oxygen content in the high concentration waste gas, and of course it can be lazy (such as nitrogen filling).

废气处理设备对高浓度废气进行预处理,对各车间内发生的废气进行剖析,存在忌讳物质的废气应分开处理。当废气管道内可能堆积风险物质时(如活性碳、叠氮化合物等)时应考虑对废气管道进行定时清洗。
The waste gas treatment equipment pretreated the high concentration waste gas, analyzed the waste gas in each workshop, and the waste gases of taboo substances should be treated separately. When waste gas pipelines may accumulate hazardous substances (such as activated carbon, azides, etc.), regular cleaning of exhaust pipes should be considered.
在废气管道规划、安装时须应考虑有一定的斜度,便利积液的排除,防止积液积累过多而导致废气管变形和残留的混合物过多,引起二次爆破;并对废气总管内的积液进行定时排液。废气管道在各风险点(如支管接入总管处)设泄爆板,以削减爆破气体大量回冲反应釜,发生连锁反应。
In the planning and installation of exhaust gas pipeline, it is necessary to consider a certain slope, facilitate the removal of liquid accumulation, prevent excessive accumulation of liquid and excessive mixture of waste gas pipe and residual mixture, cause two blasting. The exhaust pipe at each risk point (such as branch pipe access to the main pipe) is equipped with venting plates to reduce the large number of blow back gas reactors.
