布袋的简单介绍
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.
故障分析
布袋除尘器反吹清灰的故障主要有：反吹电磁阀不动作、压缩空气管路积水和回转机构卡涩。
更换除尘器滤袋步骤
1、确保花板上及花板墙壁均被清理过，扫除粉尘和其它残砾。
2、确保使用过的除尘滤袋/滤袋框架组件已经从花板孔处拆除并移真走(针对现换已使用滤袋的用户)。
3、确保除尘滤袋框架没有弯曲、损坏或毛刺等易损伤滤袋的暇疵
4、确保板孔内侧的洁净，以保证沟槽弹簧圈准确地与花板口密封。
5、确保滤袋框架卡口接口处牢固地安装好(针对两节及以上的龙骨)。
6、 把袖套插入花板孔中并让金属圈放在花板上。
7、 从专用包装箱中取出滤袋安装袖套。这些袖套是布管，两端均是开口，而一端缝有金属圈。
除尘布袋的安装
1、用手紧握滤袋开口一端的同时保持滤袋其余部份折起，并将折叠的滤袋部份推入袖套中以穿过花 板。在滤袋折叠部份在花板之下打开后，放开滤袋的顶部，让槽形垫弹簧圈架在花板上的袖套上。
2、让滤袋本身的重量缓缓固定位置，让金属圈从滤袋顶部抽出袖套。将袖套安装于花板孔内。
3、 以双手紧握槽形垫弹簧圈(不需把滤袋拉起)，双手把弹簧环圈往里压使之成“C”形。在保持 弹簧环圈成“C”形的同时，放置沟槽形弹簧圈隆起的一边到最近的花板孔边。一手握着已装嵌好的隆起的“C”形弹簧环圈的一边，另一只手把隆起的“C”形固定在花板边。
4、 一手固定隆起的“C”弹簧环圈的一边位置，另一只手慢慢地让弹簧环圈的另一边伸展张开。将弹簧环圈的槽恰好嵌入花板孔内。
5、 如果当弹簧环圈完全伸展开时不能够听到“啪”的声响，以一手的母指把弹簧环圈向板口内边推去，使弹簧环圈的槽恰好嵌入花板孔内边。
6、 一般情况下就该能够听到“啪”的声响，否则，便将弹簧环圈从另一位置再屈曲成“C”形。提 起弹簧环圈高于花板，然后再重复以上安装步骤。
7、将除尘滤袋框架安装到滤袋中。在安装时，一定要注意将框架缓慢的放入滤袋中，如果有阻力较大时，则须往上拉回一些，然后再轻轻放下，若依然阻力较大，则重复操作，直至能轻松放下。防止 框架边角划伤滤袋!严禁使框架撞击滤袋!
8、确保滤袋密封垫能很好地与花板孔面密封。
9、安装滤袋框架定位器或紧固部件，确定滤袋/滤袋框架密封垫在恰当的压力下工作。
Bag brief
Bag filter is a dry dust removal device, it is suitable for trapping fine, dry non-fibrous dust bag with textile filter cloth or non-woven mat made fabric filter role dusty gas filtered, and when the dust-laden gases enter the baghouse, the large particles, than the material of the dust settle due to gravity, fall into the ash hopper, the smaller the dust-containing gas through the filter, the dust retention so that the gas purification.
Failure Analysis
Bag filter cleaning cleaning failure: blowback solenoid valve does not operate, compressed air line hydrocephalus and slewing mechanism jam.
Replacement dust collector filter bag steps
1, to ensure that the the flower board and flower board walls are cleaned up, sweep away the dust and other residue gravel.
2, to ensure that the dust filter bag / filter bag frame components have been removed from the flowers at the plate hole and shift really take the user (for now change the filter bag).
3, to ensure that the dust filter bag frame is not bent, damage or burrs easy to damage the filter bag flawed
4, to ensure the cleanliness of the inside of the plate hole, in order to ensure accurate trench coil with flower board mouth sealed.
5, to ensure that the filter bag frame mount interface firmly installed (for two and above the keel).
6 cuff inserted into the tubesheet hole and let the metal ring on the flower board.
From a dedicated box to remove the filter bag installation cuff. These cuff is a cloth tube, both ends opening, while one end of the metal ring sewn.
Installation of the dust bag
Hand clenched filter bag opening at one end while keeping the rest of the folded filter bag, and folded the bag part of the push cuff through the flower board. In most of the filter bag folded open under the flower board, release the top of the filter bag, grooved pad coil holder in the the flower board of cuff on.
2, so that the weight of the filter bag itself slowly fixed position, the metal circle drawn from the bag at the top of the cuff. Cuff installed on the tubesheet hole.
3, with both hands clasped grooved pad coil (no need to pull the filter bag), his hands inside pressure of the spring ring to make it into a "C" shape. While holding spring ring into a "C" shaped, placed the trench-shaped spring ring the ridge side of the tubesheet holes to the nearest edge. Has assembled a good uplift of the "C" side of the ring-shaped spring held in one hand and the other hand to uplift the "C" shaped fixed tubesheet side.
4, the position of "C" in the side of the spring ring hand fixed ridge and the other hand slowly let the spring ring on the other side extending opening. Happens to be embedded in flowers of the spring ring groove plate hole.
5, not be able to hear a "pop" sound when spring ring fully extended to single-handedly mother refers to go while pushing spring ring to the plate in the mouth, the spring ring slot happens to be embedded in flowers plate hole edge .
6, under normal circumstances in relation to be able to hear a "pop" sound, otherwise, they put a spring ring from another location and then buckling into a "C" shape. Lift the spring ring is higher than the flower board, and then repeat the above installation steps.
7 framework installed dust filter bag filter bag. Installation, we must pay attention to the framework slowly into the filter bag, if there is greater resistance to be up pull back, and then gently put down, if still resistance, repeat the operation until it can easily put down. The filter bag to prevent the frame corners scratch! Non-the framework impact filter bag!
8, to ensure that the filter bag gasket can be well sealed with flower plate hole surface.
9, the installation the bag frame positioning or fastening member, determine the bag the / bag frame seal the mat in the appropriate pressure.
