摘要

设计搭建了一种新型湿式喷淋除尘试验台,喷淋塔使用湿法从气态废物中去除颗粒物控制颗粒的排放,采用喷雾与填料相结合的方式,具有优于工业中使用的其它常规设备的各种其他优点。研究了气体入口流速、粉尘入口浓度、填料高度、格栅转速等操作参数对除尘效率的影响规律。在各种因素下寻找最优组合来实现高的除尘效率,较低的排放浓度和较低的压阻。探究结果表明:与传统的单层相比,除尘效率高,与其他湿式工艺设备相比,这是一个很低的功率损失除尘器。在相同操作参数下,适当降低气体在塔内平均流速有利于提高洗涤塔的除尘效率,并且入口粉尘浓度的变化对其除尘效率的影响较大,应适当降低粉尘入口浓度。
        A new type of wet spray dust removal test bench was designed.The spray tower uses the wet method to remove particulate matter from gaseous waste to control the emission of particles.The combination of spray and filler has other advantages than those used in industry.Various other advantages of the device.The effects of operating parameters such as gas inlet flow rate,dust inlet concentration,packing height and grid rotation speed on dust removal efficiency were studied.Find the optimal combination under various factors to achieve high dust removal efficiency,lower emission concentration and lower Pressure resistance.The results of the investigation show that the dust removal efficiency can be increased by more than 5% compared with the conventional single layer,which is a very low power loss dust collector compared with other wet process equipment.Under the same operating parameters,appropriately reducing the average flow velocity of the gas in the column is beneficial to improve the dust removal efficiency of the scrubber,and the change of the inlet dust concentration has little effect on the dust removal efficiency.
