【技术解析】最详细的环保除尘设备过滤袋物理破损分析

文章发布: 发表时间: 2017-02-20 09:53:50

这些年,环保致使各职业重视,中国目前大大都职业在运用脉冲过滤袋式除尘器,包含在建工程项目中,许多运用环保除尘设备。环保除尘设备有许多长处,体积小;过滤风速高;占地面积小;易于保护等长处。
In recent years, environmental protection has attracted the attention of various professions, and most of them are using pulse filter bag filter in china. Environmental protection dust removal equipment has many advantages, small size, high filtration speed, small footprint, easy to protect and other advantages.
可是大大都客户对环保除尘设备的运用和滤袋运用不了解,乃至是一无所知。为了能使客户在运用中防止疑问和对应问题处理处理,现将脉冲清灰滤袋运用疑问和处理办法收拾供给广大用户。
But most customers for environmental protection equipment and the use of filter bag use does not understand, and is absolutely ignorant of. In order to make the customer questions and corresponding treatment to prevent problems in the application, the pulse cleaning bag use questions and treatments of the majority of users supply up.
依据过滤袋运用时出现的疑问,以及处理办法具体列出:
According to the appearance of the filter bag use questions, and lists the specific approach:
1、过滤袋袋口部位
1, filter bag parts
(1)过滤袋袋口部位破损多在袋口向下400以内,破损痕迹多为从内向外,面层首先被压缩空气吹掉落,然后基布被吹漏,终究过滤面也被吹漏。当滤袋一侧破损后,烟气一般从阻力最小的方位经过。烟气从破损处直通净气室,烟气经过期粉尘会冲刷破损处对角,终究构成袋口环状破损,乃至袋头和袋身别离。
(1) the filter bag in the bag down parts damaged within 400, for signs of damage from the inside out, the surface layer is first compressed air blowing off, then the fabric was blown leakage, eventually filtering surface have been blown leakage. When the bag side is damaged, the flue gas from the general range of least resistance after. The smoke from the breakage through the air purifying chamber, the flue gas after dust expired will scour the damaged diagonal, eventually forming a circular bag breakage, and bag head and body bags respectively.
破损因素是压缩空气过高、喷吹管歪斜、花板变形等因素构成,调整后即可防止破损。
The damage factor is too high, the compressed air blowing pipe deflection, flower plate deformation and other factors, can be adjusted to prevent breakage.
(2)过滤袋袋口破损在凹槽方位,破损痕迹多为从外向内。凹槽处被磨断,严峻时袋头掉落。
(2) the filter bag breakage in the groove direction, for signs of damage from the outside. The groove is worn off, when the bag is falling.
破损因素是设备不妥或袋口直径小。
The damage factor is wrong or small diameter bag equipment.
(3)过滤袋袋口外侧破损在喷吹管和花板长度范围内,破损痕迹由外向内,纤维和基布均被磨损或磨断,乃至掉落。
(3) the filter bag breakage in injection pipe and lateral plate length range, signs of damage from the outside to the inside, and the fiber base cloth are wear or wear off, and fall.
破损因素是大都为设备不良,袋口小或压差过高,使滤袋脱离多孔板顶在喷吹管或除尘器盖板上,终究磨擦破损。多见于高炉煤气除尘上。
The damage factors are mostly poor equipment, low or high pressure bag, the bag from the top blowing in the porous plate or dust cover, eventually friction damage. More common in the blast furnace gas dust.
2、滤袋袋身方位
2, the bag bag body range
(1)过滤袋外侧有条状磨损
(1) the outer side of the filter bag is striped
① 假如破损痕迹由内向外,破损在袋笼竖筋上,阐明是袋笼竖筋脱焊或锈蚀,将滤袋磨断或喷吹压力过高、喷吹过于频频,使滤袋与袋笼触摸方位折叠开裂破损。替换袋笼即或调整喷吹设备可处理疑问。
If the signs of damage from the inside out, broken bag cage vertical reinforcement, vertical reinforcement bag cage is clarified desoldering or rust, will wear off the bag or injection pressure is too high, blowing too frequently, so that the bag and the bag cage touch range folding craze. Replace the bag cage or adjusting the injection device can process queries.
②假如破损痕迹由外向内,破损在袋笼竖筋上,阐明是袋笼变形致使滤袋和滤袋之间磨擦使其破损,替换袋笼即可防止破损。
If signs of damage from the outside to the inside, broken bag cage vertical reinforcement, this is causing friction between the filter bag cage deformation and the bag is damaged, replace the bag cage can prevent breakage.
(2)过滤袋袋身过滤面有渐进式磨损,多发于袋笼支持环下部方位,而上部却很少。此类破损是烟尘冲刷致使,疑问出在气流散布不均、过滤风速过高等因素构成的。
(2) the filtering surface of the filter bag body has progressive wear, which occurs in the lower part of the supporting ring of the bag cage, while the upper part is very small. This kind of damage is caused by smoke and dust, which is caused by the uneven distribution of airflow and the high filtration speed.
3、过滤袋下部破损
3, the lower part of the filter bag damage
(1)过滤袋下部外侧破损多见于滤袋底部向上300mm以内,破损多在一侧,下部最为严峻,向上逐步减轻。部分缝纫线会被磨断,没有遭到磨损的方位缝纫线强力杰出。此类破损多见于多孔板变形、多孔板距离过于严密、袋笼变形、滤袋过长等因素构成。单个有过滤袋和除尘器箱壁磨擦破损的。此类破损需严厉查看多孔板水平度,差错要一平方米小,〈1/1000,应运用制造精良的袋笼。
(1) the filter bag in the bag outside at the bottom to damage within 300mm, damage on the side, is the most severe, to gradually reduce. Part of the sewing thread will be worn off, without wearing the orientation of the sewing thread is strong. Such damage in porous plate deformation, porous plate distance too tight, too long, bag bag cage deformation and other factors constitute. A single filter bag dust collector and tank wall friction damage. This kind of damage need to strictly check the level of the porous plate, the error to a square meter small, "1/1000, should be used to make a good bag.
(2)过滤袋下部环状破损多见于过滤风速较高的除尘器或磨琢性较强的粉尘,当过滤袋一侧破损后,烟尘冲刷破损对角,跟着时间推移破损不断扩大,过滤袋破损严峻可致使滤袋环形开裂。
(2) the lower part of the filter bag dust collector in annular damage higher filtration rate or grinding dust resistance strong, when the filter bag side broken, dust erosion damaged diagonally, as time passes, damage continues to expand, can cause severe damage to the filter bag filter bag ring cracking.
(3)滤袋下部内侧磨损多见于与袋笼触摸方位,大都是袋笼和袋笼底直径相差太大,构成滤袋清灰和过滤时改换幅度过大,和袋笼磨擦破损。替换优异袋笼即可处理。
The lower part of the filter bag (3) found in the bag cage and inner wear touch range, mostly bag cage and bag cage bottom diameter is too large, a bag cleaning and filtering when the change rate is too large, and bag cage friction damage. Replace the excellent bag cage can handle.
4、过滤袋底部破损
4, the bottom of the filter bag damage
(1)过滤袋底部破损多见于外侧,破损外表有显着磨损痕迹。底部缝纫线被磨断,滤料基布被磨断,严峻时袋底破损或全体掉落。调整除尘器灰斗卸灰作业,防止粉尘堆积过高构成涡流磨损滤袋。
(1) the breakage of the bottom of the filter bag is more common in the outer side, and there are significant wear marks on the damaged surface. The bottom line is sewing wear off, filter cloth is worn off, severe damage or the bottom of the bag drop. Adjust the precipitator hopper discharging operation, to prevent excessive dust accumulation form vortex wear bag.
(2)过滤袋底部内部磨损,多见于袋笼底部过小或滤袋过长,袋笼只能制撑袋底部分。过滤袋清灰和过滤时动作过大构成滤袋底内侧磨损。
(2) at the bottom of the filter bag inside the wear in bag cage is too small or too long at the bottom of the bag, bag cage can only support system at the bottom of the bag. The filter bag cleaning and filtering Dongzuoguoda a bag bottom inner wear.
(3)过滤袋内侧破损多是袋笼外径和过滤袋内径相差过大,构成过滤袋清灰和过滤时动作过大构成滤袋内侧磨损。
(3) the filter bag is damaged inside the filter bag bag cage diameter and diameter is too large, a filter bag cleaning and filtering Dongzuoguoda composed of filter bag wear.
(4)过滤袋内侧破损方位在袋笼处,磨损处有锈蚀痕迹,多是袋笼腐蚀后便面构成有锋芒的氧化层,此时的袋笼外表和砂纸差不多,每清灰一次就会严峻磨擦过滤袋一次,终究磨损过滤袋。替换优异袋笼即可。
(4) the filter bag inside the damaged position in the bag cage, there are traces of corrosion wear, is corrosion after bag cage surface oxide layer edge, the bag cage looks and almost every cleaning sand, a severe friction filter bag, filter bag will wear. Replace excellent bag cage.
