延长环保除尘设备滤袋使用寿命的方法

文章发布: 发表时间: 2017-03-31 09:48:04

滤袋是决定环保除尘设备除尘功率和作业温度的要害元件,替换滤袋的费用又是环保除尘设备的首要修理费用。因而滤袋的作业寿数关系到环保除尘设备的运转状况和本钱!
The filter bag is the key element to decide the dust removal power and operating temperature of the environmental protection dust removing equipment. The work life related to environmental protection equipment operating conditions and the cost of the bag!
延伸环保除尘设备滤袋运用寿数的办法:
Extension of environmental protection equipment bag using his way:
1 选用合适的滤材
1 select the appropriate filter
选用滤材应根据气体的温度和化学特性;颗粒物大小、分量、外形、有否啄磨性以及含尘浓度、过滤速度、清灰方法、排放浓度和袋式除尘器的作业制度等因素综合思考。
The filter should be based on the temperature and chemical properties of gases; particle size, weight, shape, comprehensive consideration of working system and other factors not peck grind and dust concentration, filtration velocity, dust emission concentration method, and bag type dust collector.
通常情况下,脉冲喷吹环保除尘设备选用针刺毡;分室反吹环保除尘设备或机械振打环保除尘设备选用机织布。
Under normal circumstances, the pulse jet environmental protection dust removal equipment selection of needle felt; sub chamber back blowing environmental protection dust removal equipment or mechanical vibration environmental protection dust removal equipment selection machine.
2 规划合理的构造
2 planning reasonable structure
​滤袋的构造应满意与其般配的环保除尘设备过滤与清灰的请求,且设备便利、密封牢靠,寻求相应的过滤面积和杰出的过滤状况,易于清灰而又尽量避免磨损。与相关部件合作合理。
The bag structure request of environmental protection equipment and satisfactory filtering match with ash, and the equipment is convenient, reliable sealing and seek corresponding filtration area and excellent filtration condition, easy cleaning and avoid wear. Work with related components.
如外滤式合成纤维滤袋与结构应是松动合作,外滤式玻璃纤维滤袋应与小距离竖筋结构紧密合作;内滤式滤袋应思考和设定滤袋涨力。
Such as external filter type synthetic fiber filter bag and the structure should be loose cooperation, the external filter glass fiber filter bag should be closely linked with the structure of the small vertical ribs; internal filter bag should be considered and set up the filter bag.
3 精深的缝制技术
3 deep sewing technology
技术领先,缝制尺度契合规划请求,并按滤料品种和运用温度,预留热收缩尺度;装备齐全,缝线针距合理,无跳针、断线,缝线契合请求;配件优异,合作合理,无毛刺或开裂而
Leading technology, sewing scale fit and press media planning request, varieties and application of temperature, thermal contraction reserve scale; complete equipment, suture needle distance is reasonable, no jumping, break, suture requirements; excellent accessories, reasonable cooperation, no burr or cracks
损坏滤袋;全部滤袋无小孔、跳纱、污损等缺点,并有适当的包装,在储运途中不损坏或受潮。玻纤滤袋不该重压、储存期过长,否则将影响运用寿数。
Damage to the filter bag; all the filter bag without holes, jumping, fouling and other shortcomings, and have the appropriate packaging, storage and transportation on the road without damage or moisture. The weight of glass fiber filter bag is not, the storage period is too long, otherwise it will affect the use of life.
4 准确的运用办法
4 accurate use of methods
外滤式滤袋设备方法
External filtering bag device method
袋口与多孔板牢靠密封与固定;
Sealing and fixing of bag mouth and porous plate;
滤袋笔直悬空在多孔板下面;
The bag is directly under the porous plate;
相邻滤袋不相互磕碰;
Don't bump each other adjacent bags;
滤袋与结构合作准确,结构笔挺无毛刺。
The bag and the structure of cooperative structure accurately, straight without burr.
内滤式滤袋设备方法
Method for filtering bag filter
滤袋上端装有袋帽且经过吊挂设备悬挂在除尘器横梁上,下端与下袋牢靠密封和固定;
The upper end of the filter bag is provided with a bag cap and is hung on the dust collector crossbeam through the hanging device;
滤袋设备应调整张力到达规定值,使滤袋在过滤和反吹时不松动和掉落,并在运用第一周和第一个月后再各调整一次;
The bag filter equipment should adjust the tension to reach the specified value, so that the filter bag in the filter and back blowing is not loose and fall, and in the first week and the first month after each adjustment;
滤袋内各配件(防瘪环)合作准确,一切配件不该有毛刺或开裂。
All parts of the filter bag (anti deflated ring) cooperate accurately, all fittings should not have burr or crack.
牢靠有用清灰
Reliable and useful ash removal
滤袋在运用中,迎尘面积灰逐步增多、压差上升,应经过有用清灰,隔离粉尘,使滤袋内外的压差保持在设定的范围内。
In the application of the filter bag, the ash content of the dust rising gradually, the pressure difference increases, and should be used to remove dust, so that the pressure difference between the inside and outside of the filter bag is kept within the set range.
避免突发异常情况
Avoid unexpected situations
环保除尘设备在运转时,应避免突发异常情况,如气体温度俄然增加、或腐蚀性气体进入、或气体温度突然降低至露点以下等等,受温度、湿度、化学腐蚀性、机械磨损或冲击等因素超过滤袋的耐受力而损坏。
Environmental protection equipment in operation, should avoid unexpected abnormal situations, such as gas temperature suddenly increased, or corrosive gas or gas into, the temperature suddenly decreased to below dew point temperature, humidity, etc., chemical corrosion resistance, mechanical wear and impact damage tolerance than bag.
