焊接烟尘治理系统排放浓度多少合适?

焊接烟尘治理系统是焊接车间工位排烟的必备除尘设备,并且和移动式焊接烟尘净化器单独净化焊烟的工作方式有非常大的区别,是针对整个焊接车间的大型焊烟处理方案。
Welding fume control system is the necessary dust removal equipment for welding workshop, and it is different from the working mode of mobile welding fume purifier to purify welding fume separately. It is a large-scale welding fume treatment scheme for the whole welding workshop.
焊接烟尘治理系统设会根据车间的实际需求工况定制除尘方案,集尘罩会根据工位大小和焊点的分部情况进行尺寸设计,以求在范围内收集焊接烟尘,为了出现防止跑烟状况,可以在集尘罩外围安装一圈防弧光帘,或者在集尘罩吸风口安装特制的档板,以增强对边缘区域焊烟的收集能力。
During the design of the welding fume control system, the dust removal scheme will be customized according to the actual demand of the workshop. The dust collecting cover will be designed according to the size of the working position and the subsection of the welding spot, so as to collect the welding dust within the maximum range. In order to prevent the smoke from escaping, a circle of arc proof curtain can be installed around the dust collecting cover, or a special baffle plate can be installed at the suction outlet of the dust collecting cover Enhance the ability of collecting welding fume in edge area.
统计车间的焊接岗位和车间长度,预估整个车间生产的焊烟数量,及有效净化需要的过滤面积,从而确定焊接烟尘治理系统主机安放的滤芯数量,风机功率选择同样来自车间工位的分布情况,无论是近主机端还是远主机端都要确保管道开口有足够风量。
车间除尘设备
According to the statistics of welding posts and workshop length in the workshop, the quantity of welding fume produced in the whole workshop and the filtering area required for effective purification are estimated, so as to determine the number of filter elements placed by the main engine of the welding fume treatment system, and the fan power selection also comes from the distribution of the workshop positions. No matter whether it is near or far from the main engine end, it is necessary to ensure that there is enough air volume at the pipe opening.
客户对焊接烟尘治理系统更关心的还是更终的焊接烟尘处理效果,因为集中除尘系统有足够的风量和滤筒,所以它的烟尘净化效果远比移动式焊接烟尘净化器效果要好,室内检测电焊烟尘浓度只有3~4mg/m3,远高于国内现行标准。
Customers are most concerned about the final treatment effect of welding fume. Because the centralized dust removal system has enough air volume and filter cartridge, its fume purification effect is far better than that of mobile welding fume purifier. The indoor detection of welding fume concentration is only 3 ~ 4mg / m3, which is far higher than the current domestic standard.
大型焊接车间除尘还要遵循环保部门对烟尘有组织排放的规定,当然焊接烟尘治理系统有15m的高空管道进行排放,可以满足有组织排放的规定。整套焊接车间除尘设备室外的焊烟排放浓度在30mg/m3之内(可在排烟管道的预留窗口进行检测),同样在规定标准水平之上,应对环保检查没有任何问题。
The dust removal of large welding workshop should follow the regulations of environmental protection department on the organized emission of smoke and dust. Of course, the welding fume control system has 15m high-altitude pipeline for discharge, which can meet the requirements of organized emission. The welding fume emission concentration outside the dust removal equipment of the whole welding workshop is within 30mg / m3 (it can be detected in the reserved window of the smoke exhaust pipe), which is also above the specified standard level, so there should be no problem in environmental protection inspection.
相信看了本文的车间除尘设备http://www.yinyehuanbao.com介绍后,对这方面也会有自己的一番认识,以后针对的等问题也能很好的解决。
