山东能源新矿集团华丰煤矿完成的“局部通风降温除尘净化器”创新成果获得国家实用新型专利。该装置包括一节3～6m长的铁风筒,在铁风筒的进风侧周边均匀布置若干净化喷雾头,各喷雾头的喷雾中心线与铁风筒轴线顺风流方向呈30。,在铁风筒的底部焊有凹槽,用于临时储存污水,凹槽底部安装排污管,用于污水排放。由于该装置设在局部通风机后的风筒中,喷雾能封闭风筒全断面,比在风机前安设净化喷雾降尘效果好,总粉尘浓度可降至1.3mg/m~3左右。喷雾水聚集后由排污管排出到水沟中,不会
Shandong Energy Huafeng Coal Mine Group completed the “local ventilation and cooling dust purifier ” innovation achievements of national utility model patents. The device comprises a section of 3 ~ 6m long iron duct, and a plurality of purifying spray heads are evenly arranged around the air inlet side of the iron duct. The spray center line of each spraying head and the axis of the iron duct are in the direction of the windward flow. , In the bottom of the iron duct welded groove, for the temporary storage of sewage, the bottom of the groove to install sewage pipes for sewage discharge. Since the device is arranged in the air duct behind the local ventilator, the spraying can close the whole section of the air duct, and the effect of reducing the dust is better than installing the decontamination spray in front of the air blower. The total dust concentration can be reduced to about 1.3mg / m ~ 3. After the spray water is collected, it will be discharged to the ditch by the sewage pipe, no
