除尘布袋的生产需办理工业产品生产许可证吗

　　有的买家在购买到物品以后，就会问到除尘布袋的生产需办理工业产品生产许可证吗?这个是需要的，根据你所在的地区不同。相对于的管理部门流程也是不一样的，如果你是河北泊头地区的生产厂家，可以咨询三融环保可以帮到你。今天来给大家讲述一下除尘布袋。
　　除尘器或除尘设备就是把粉尘从烟气中分离出来的设备。而布袋除尘器也称为过滤式除尘器,是一种干式高效除尘器，它是利用纤维编织物制作的袋式过滤元件来捕集含尘气体中固体颗粒物的除尘装置。其作用原理是尘粒在绕过滤布纤维时因惯性力作用与纤维碰撞而被拦截。
　　在脉冲和气箱式脉冲除尘器中，粉尘是附着在滤袋的外表面。含尘气体经过除尘器时，粉尘被捕集在滤袋的外表面，而干净气体通过滤料进入滤袋内部。滤袋内部的笼架用来支撑滤袋，防止滤袋塌陷，同时它有助于尘饼的清除和重新分布。
　　除尘布袋的面料和设计应尽量追求高效过滤、易于粉尘剥离及经久耐用效果。除尘布袋的选用至关重要，它直接影响除尘器的除尘效果，选取用除尘布袋从下列几个方面选取择:气体的温度，潮湿度和化学性，颗粒大小，含尘浓度，过滤风速，清尘方式等因素。
　　新型环保技术的除尘器布袋，尤其是一种凹凸式折叠除尘布袋。其中内框架与外框架所组合构成的截面形状为周边相对折角凹凸成型形式，除尘布袋滤料与内框架、外框架所形成的整体为径向折叠式封闭圆筒结构。本实用新型是一种结构简单、制造容易的折叠式除尘布袋。在相同的除尘处理风量的前提下，由于该折叠式除尘布袋有效增大了过滤面积，因此除尘器体积减小、节省了占地空间、节约了设备的制造投资。这种布袋除尘器具有较高的净化除尘效果和良好的清洁反冲效果，并且有利于延长除尘布袋的使用寿命。
　　滤袋的面料和设计应尽量追求高效过滤、易于粉尘剥离及经久耐用效果。
　　1.毛细纤维吸油滤袋 由预过滤层、主过滤层和丝网罩三部分组成。是专为有效地吸附液体中的油脂而设计的。过滤材料中的空隙率高达80%，大大提高了产品的使用寿命。吸油量高达滤袋自身重量的12~20倍(具体因流体和油脂特性、流速而异)
　　2.绝对精度无缝滤袋 由纯聚丙烯毛细纤维热熔喷成型。外层为加厚深层过滤材料，用以提供分层过滤; 内套大口径滤芯，用以进一步增强整体的深层过滤效果，提高容纳杂质能力。使用寿命平均为普通聚丙烯滤袋的五倍以上。最高过滤精度为3um。领环为塑料环。
　　3.丝网滤袋 供选材料有尼龙单丝网、聚酯单丝网、聚丙烯多股丝网。最高过滤精度20um 特点:绝对过滤精度、高韧性、抗破坏、无纤维游离、可反复使用。
　　布袋除尘器的布袋工作原理
　　布袋除尘器是一种干式除尘装置,它适用于捕集细小、干燥非纤维性粉尘。滤袋采用纺织的滤布或非纺织的毡制成，利用纤维织物的过滤作用对含尘气体进行过滤，当含尘气体进入布袋除尘器，颗粒大、比重大的粉尘，由于重力的作用沉降下来 ，落入灰斗，含有较细小粉尘的气体在通过滤料时，粉尘被阻留，使气体得到净化。
　　一般新滤料的除尘效率是不够高的。滤料使用一段时间后，由于筛滤、碰撞、滞留、扩散、静电等效应，滤袋表面积聚了一层粉尘，这层粉尘称为初层，在此以后的运动过程中，初层成了滤料的主要过滤层，依靠初层的作用，网孔较大的滤料也能获得较高的过滤效率。随着粉尘在滤料 表面的积聚，除尘器的效率和阻力都相应的增加，当滤料两侧的压力差很大时，会把有些已附着在滤料上的细小尘粒挤压过去，使除尘器效率下降。另外，除尘器的阻力过高会使除尘系统的风量显著下降。因此，除尘器的阻力达到一定数值后，要 及时清灰。清灰时不能破坏初层，以免效率下降。
　　布袋除尘器结构主要由上部箱体、中部箱体、下部箱体(灰斗)、清灰系统和排灰机构等部分组成。 布袋除尘器性能的好坏，除了正确选择滤袋材料外，清灰系统对布袋除尘器起着决定性的作用。为此，清灰方法是区分布袋除尘器的特性之一，也是布袋除尘器运行中重要的一环。
　　大家别再犹豫了，泊头三融环保有限公司有着多年的除尘布袋生产经验，引进国内先进生产线及检测设备，选用国内外最优质的原料，在国内处于领先水平，经过权威部门测试，性能高于国家标准。三融环保除尘布袋从生产原料源头把关，生产出让客户放心让工程安全的高品质产品。
