运用维护的通常疑问及注意事项可分为粉尘排放超支、新莆京www483net压力比速高以及滤袋的运用寿命过短等三个方面，这三个方面有显着的相关，概况如下：
The application of maintenance usually doubt and attention can be divided into dust discharge pressure overruns, environmental protection equipment and high specific speed bag using the short life of three aspects, these three aspects have significant correlation, as follows:
一、粉尘排放超支
First, excessive dust emissions
形成粉尘排放超支的根本因素
The fundamental factor of dust emission
1、 滤袋外表的初始层不行
1, the initial layer of the filter bag is not
?2、 滤袋破损
2, filter bag damage
3、 滤袋设备不良
3, filter bag equipment
分别叙说如下：
The following narrative:
1、 滤袋外表的初始层不行
1, the initial layer of the filter bag is not
在新莆京www483net的运转中假如排放超支且除尘器的运转压力比规划过低，极有也许是滤袋外表的初始粉尘缺乏，其因素也许是滤袋的过滤速度过高、滤袋的清洁周期过短。喷吹压缩空气的压力过高，粉尘的负载性下降一级。
In environmental protection equipment in operation if emissions overruns and precipitator operating pressure ratio planning is too low, is perhaps the lack of initial dust filter bag surface, the factors may be too high, the filtration rate of filter bag filter bag cleaning cycle is too short. The pressure of the compressed air is too high and the load of the dust is decreased.
在研讨标明，过高的过滤速度，粉尘的排出率会添加。过高的过滤气速，会使初始粉层破碎，以及粉尘充击滤袋而形成过度磨损，假如此刻清洁滤袋次数过高很简单倒至滤袋的织物松懈，这些都会使除尘器排放超支。
In the study indicated that the high filtration rate, dust discharge rate will be added. High filtration velocity, the initial powder layer is broken, and the dust charging bag and the formation of excessive wear, if this number is too high is very simple but clean bag to bag fabric lax, these will make dust emissions overrun.
在设定新莆京www483net脉冲清洁的周期时，以能确保除尘器作业在安稳的压力下，设定的脉冲清洁周期时刻最长为好，脉冲清洁时刻以能确保初始粉尘不掉落，设定的时刻清洁最短为好。
In the setting of environmental protection equipment pulse cleaning cycle, to ensure safe operation in the precipitator under the pressure of set pulse cleaning cycle the longest time as well, to ensure that the initial time of pulse cleaning dust does not fall, set time cleaning the shortest as well.
假如初始粉尘层缺乏，能够选用延伸清洁周期抵偿，假如运用压差操控，能够进步除尘器的进出口压力设定的安稳性。
If the initial lack of dust layer, can be used to extend the cleaning cycle compensation, if the use of differential pressure control, can improve the stability of the dust collector inlet and outlet pressure setting.
假如新莆京www483net超支排放仅仅是在清洁滤袋以后发作，则只需查看脉冲清洁的压缩空气的压力是不是过大。
If the exhaust emissions of environmental protection equipment is only after the clean filter bag, just check the pulse clean compressed air pressure is not too large.
粉尘的负载下降也许来自生产率的下降，或许是除尘器的操控体系的修理，调整形成的。处理的办法：能够选用轻负荷渐渐开端升载或许选用预覆粉尘的办法来处理。
The decline in the load of dust may come from the decline in productivity, perhaps the repair of the dust collector's control system. Approach: to choose a light load gradually began to rise or may choose to cover the dust to deal with.

2、 滤袋破损(磨损、焚毁、腐蚀)
2, filter bag damage (wear, burning, corrosion)
滤袋的运用占新莆京www483net的修理费用最大，最高可达修理费的70%以上，其根本的状况是磨损、焚毁、腐蚀等。处理的办法能够选用以下几种办法：
The use of filter bags accounted for the largest cost of environmental protection dust removal equipment, up to more than 70% of the repair costs, the fundamental situation is wear, burning, corrosion, etc.. The following measures can be adopted to deal with the problem:
(1) 磨损
(1) wear
过高的过滤气速、致使粉尘充击、磨损滤袋、也使滤袋的织物纤维张力受损、处理的办法：调整除尘器的废气流量，当预期的流量改动较大，能够添加流量自动操控体系以确保除尘器作业在安稳的气量。
High filtration velocity, resulting in dust charging, wear bag, also make the fabric tension bag deal damage, adjustment of exhaust gas flow dust collector, when the desired flow changes greatly, can add flow automatic control system to ensure the safe operation of gas in the dust collector.
新莆京www483net的透气散布不均，简单使高含量的含尘废气直接充击有些滤袋，简单使废气进口有些滤袋穿孔，运用周期过短。处理的办法：在除尘器进风口导管处设备进气散布导板，或者针对经常磨损部位的滤袋替换成耐磨的滤袋。
The dust removal of the environmental protection dust removal device is uneven, and the high content of dust and waste gas can be directly filled with some filter bags, so that some filter bags of the exhaust gas are perforated. Treatment method: in the dust collector inlet duct equipment inlet air distribution guide plate, or for the often worn parts of the filter bag into a wearable filter bag.
滤袋间的间隔过小，龙骨曲折等简单形成滤袋间的磨损，例如玻璃纤维之间磨损很灵敏。应调整设备结实滤袋并替换曲折的龙骨。
The interval between the filter bags is too small, and the formation of the bag is easy to wear, such as the abrasion between the glass fiber is very sensitive. The equipment should be adjusted to replace the zigzag keel.
滤袋与龙骨的直径相差联系，太小时清洁作用欠安，应进步清洁周期和进步喷吹空气的压力，太大时滤袋与龙骨的磨擦会加快磨损，较佳的配合为滤袋比龙骨的周长大10～20mm，长度应当共同，对某些滤布随温度改动较大，并且有伸长的特性时需特别注意。
The bag with the keel of the diameter difference, too clean effect not beautiful, should blow air cleaning cycle progress and progress of spray pressure, too much friction with the keel of the bag will accelerate wear, with better than for bag keel Zhou Changda 10 ~ 20mm, the length should be jointly, for some cloth with temperature changes greatly, and the elongation characteristics need special attention.
龙骨爆接处有破洞或毛刺时，或因腐蚀发作的粗糙的外表，亦会加快滤袋的磨损。
When the keel is cracked or broken, or because of the rough appearance of corrosion attack, it will also accelerate the wear of the filter bag.
滤袋与多孔板密封不严，会形成滤袋顶端反裙处磨损，选用带有弹性环的比较好。
The filter bag and the porous plate seal is not strict, can form the top of the filter bag reverse skirt to wear, the choice has the elastic ring quite good.
文氏管或脉冲管相对滤袋对齐不正，简单合滤袋上端发作机械磨擦，应调整。
The venturi tube or the pulse tube is not aligned with the filter bag, and the upper end of the filter bag is mechanically damaged.
滤袋清洁太频频会加快滤袋的磨损，应调整。
Filter bag cleaning too often will speed up the bag wear, should be adjusted.
废气中含尘超过规划标准，也会使滤袋加快磨损。
Waste gas containing dust over the planning standards, but also to accelerate the wear of the bag.
除尘器集灰斗储存的粉尘过多，也会加快滤袋的磨损。
Precipitator dust ash storage too much, will accelerate the wear of the filter bag.
上述因素均会使新莆京www483net排放超支，并且也会削减除尘器元器件的运用寿命，应注重。
All of the above factors will make the environmental protection dust removal equipment overrun, and will also reduce the life of dust collector components, should pay attention to.
(2) 焚毁
(2) burn down
形成除尘器滤袋焚毁的因素，首要是废气的温度过高所至假如除尘器长时刻处理的废气温度超过滤袋的作业条件，简单使滤袋硬性缩短，或融化发作破洞，以及废气中的火星流入，或粉尘发热，也也许使滤袋烧成孔洞，在选择滤袋时特别重要。
The formation factors of burned dust bag, the first is the temperature of the exhaust gas of high temperature exhaust gas to dust if long time processing over bag working conditions, so that the bag is simple hard shortening or melt attack holes, and the exhaust gases or dust into Mars, fever, also may make the bag firing holes, especially important in the choice of filter bag at.
假如需求将废气降温，选用冷却办法时，要注意空气的湿度、是不是富含酸碱成份，一起要尽量确保除尘器处理的废气的温度高于露点以上，并避免水滴直接进入滤袋。
If the demand will exhaust cooling, cooling way selection, should pay attention to the humidity of the air, is not rich in acid-base components, together to try to ensure that the exhaust gas dust treatment is higher than the temperature above the dew point, and avoid water directly into the bag.
为避免火星进入除尘器，使滤袋遭到烧损，也许选用预处理办法，比方：在滤袋的外表预覆一层维护层，能够选用高岭士，石灰石粉等。一起要避免未燃碳物质在除尘器二次燃烧。
In order to avoid the dust into the dust, so that the filter bag has been burned, perhaps the use of pretreatment methods, such as: the filter bag in the surface of a layer of pre maintenance layer, can choose kaolin, limestone powder, etc.. Together to avoid unburned carbon material in the dust collector two combustion.
(3) 腐蚀
(3) corrosion
腐蚀的首要因素是废气中富含酸、碱性成份，跟着这些化学物质气体的浓度改动而改动露点，假如除尘器开机或停机在露点以下时，废气中的SO2遇水形成H2SO2形成滤袋纤维变形然后失掉强度，避免的办法是选用耐酸、碱的滤袋，将除尘器进气管道、外壳保温，有条件的状况下能够给除尘器加温。
The primary factor of corrosion is rich in acid and alkaline waste composition, concentration of these chemicals with gas changes and the changes of dew point, if the dust boot or shutdown at below the dew point, the SO2 in the exhaust gas water formation H2SO2 bag fiber deformation and then avoid losing strength, the way is to choose the acid and base of the filter bag, the precipitator inlet pipe shell, thermal insulation, heating can give conditions under the condition of a dust collector.
废气中的凝露珠还会形成滤袋的阻塞，当滤袋外表的初始粉尘层因为水分的因素，干燥后会使粉尘凝聚、板强，然后致使滤袋失掉了弹性，假如在此条件下脉冲清洁滤袋将加快滤袋的损坏。
In the exhaust gas will form the gel bead bag bag when blocking, the initial appearance of dust layer because of moisture factor, after drying can make dust condensation, plate, and then the bag lost elasticity, if will speed up the bag cleaning bag under the condition of pulse damage.
选用新莆京www483net停机后再脉冲反吹清洁滤袋若干次，对维护滤袋有利。
After selecting the environmental protection dust removal equipment and then pulse cleaning bag several times, on the maintenance of the filter bag.
二、阻力过高
Two, high resistance
新莆京www483net的阻力在除尘器的规划中已经决定，但是在除尘器的运转中，假如发现除尘器的阻力在短时刻急剧添加，则表明除尘器出现疑问，应及时进行修理调整。
Environmental protection equipment resistance has decided in the collector's plan, but in the dust collector operation, if it is found that the resistance of the dust collector is added rapidly in a short time, indicates that the dust remover of doubt, should be timely repair adjustment.
阻力过大的因素能够分为两种：
Excessive resistance factors can be divided into two:
1、 新莆京www483net在体系运转后马上发作;
1, environmental protection dust removal equipment immediately after the operation of the system;
2、 新莆京www483net作业一段时刻后发作;
2, environmental protection dust removal equipment operation after a period of time;
假如是新莆京www483net的规划不妥，简单形成第一种现象的发作
If it is the planning of environmental dust removal equipment is not appropriate, the formation of a simple phenomenon
形成第二种是操作疑问和修理方面所致：首要因素是滤袋的清洁不良，滤袋阻塞，进气分配不匀，扼要如下：
The formation of the second is the operation of doubt and repair caused by: the primary factor is the poor cleaning of the filter bag, filter bag blocking, air distribution is not uniform, as follows:
(1) 清洁设备调整不良：
(1) poor cleaning equipment:
查看压缩空气的质量是不是富含油、水;
Check the quality of compressed air is not rich in oil, water;
查看供气管道是不是晓畅;
Check the gas supply pipe is not smooth;
查看脉冲电磁阀作业是不是正常，紧固螺栓是不是松动，膜片是不是损坏，电磁线圈是不是松协，阀芯是不是卡住。
View pulse solenoid valve operation is not normal, the fastening bolts are not loose, the diaphragm is not damaged, the electromagnetic coil is not loose association, the spool is not stuck.
次序操控仪的设定是不是符合要求，是不是有所改动;
The order of the instrument is set to meet the requirements, is not changed;
喷气支管、文氏管是不是设备精确。
Is it accurate to use the jet manifold and Venturi tube.
(2) 滤袋的阻塞
(2) filter bags blocking
滤袋的阻塞首要因素是过滤速度过大，粉尘过细，粉尘具有粘性，滤袋清洁不良，滤袋受损。
The primary factor is the obstruction of bag filter speed is too large, too much dust, dust sticky, bad cleaning bag, the bag is damaged.
假如新莆京www483net运转的过滤气速超过滤袋的规划标准，则很简单致使废气中的微细粉尘卡住在滤袋纤维内部，然后发作滤袋阻塞。
If the environmental protection dust removal equipment operation of the filter gas faster than the filter bag planning standards, it is very easy to cause the waste gas in the micro dust stuck in the bag inside the fiber, and then attack the filter bag blocking.
选用覆膜滤料或在滤袋的外表预覆维护性粉层，是比较好的办法。
It is a good way to use the plastic film material or the surface of the filter bag to protect the powder layer.
关于粘性大的粉尘，则需求下降过滤气速，或增大脉冲喷吹的压力，或选用离线脉冲清洁滤袋的办法，但比较好的办法是添加过滤面积，以利下降过滤速度，延伸滤袋的运用寿命。
Dust on large viscosity, the demand decline or increase the filtration velocity, pulse pressure injection, or the use of off-line pulse cleaning bag, but a better approach is to add the filtering area, to decrease the rate of filtration, filter service life extension.
滤袋清灰不良的首要包含清灰次数频频，清灰时刻过长，清灰次数过频简单使滤袋纤维组织松懈然后添加废气中的微细粉尘阻塞滤袋，清灰时刻过长会滤袋外表的初始粉尘同时清理掉。
Bag cleaning mainly includes the bad times of cleaning frequently, cleaning time is too long, the frequency of cleaning frequency is simple so that the bag of fibrous tissue lax and then add fine dust in the exhaust gas blocking dust cleaning bag, the initial time is too long will also clean up the appearance of the bag.
假如清灰时刻过短，滤袋外表的粉尘还没彻底清洁洁净时，随即开端进行过滤，粉尘逐渐累积在滤袋的外表，然后形成滤袋的阻塞，在处理这种疑问时，能够经过几回试运转进行调整。
If the cleaning time is too short, the appearance of the dust filter bag is not completely clean, then start to filter the dust accumulated in the bag appearance, then form the filter bag in this block, when in doubt, can adjust back after several test run.
滤袋受潮的因素：除尘器壳体密封不严漏水，进入含湿空气，用于反吹清灰的压缩空气不洁净(含油、含水)、用于清灰的压缩空气太冷。
Filter bag damp factors: dust tight enclosure leakage, into the wet air, for the back blowing dust cleaning of compressed air is not clean (oil, water), used for cleaning the compressed air is too cold.
为避免滤袋受潮，在冰冷的区域，可将用于清灰的压缩空气添加保温、降温、除油、除水。在除尘器停机后再持续清灰10～20分。
In order to avoid the filter bag is damp, in the cold area, can be used for cleaning the compressed air to add insulation, cooling, degreasing, water removal. Dust removal in the machine and then continue to clear ash 10 ~ 20 minutes.
水分是滤袋阻塞的最大因素。形成富含水分的因素通常是低温发作凝露，特别在处理燃烧或高温烟气时，对这么的状况能够选用以下的办法用于避免：
Moisture is the most important factor of filter bag blockage. The formation of water rich factors are usually low temperature onset of condensation, especially in the treatment of burning or high temperature flue gas, the situation can be used for the following methods to avoid:
① 避免不妥开机;
Avoid improper boot;
② 避免在新莆京www483net阻力大时开机;
Avoid environmental dust removal equipment when the resistance is large;
在低于露点时开机：
Boot at below dew point:
在新莆京www483net停机后滤袋外表有冷凝水时从头开机，如此刻进入很多的含尘空气，加上高湿度将致使滤袋外表泥泞;
In the environmental protection dust removal equipment after the filter bag when there is condensation of water from the start, so many of the dust into the air, coupled with high humidity will cause the appearance of the filter bag muddy;
为避免这种状况，应预热除尘器进口含尘空气，或预覆粉尘层。
In order to avoid this situation, it is necessary to preheat the dust laden air from the dust collector, or to pre dust layer.
③ 在低于露点开机
Below the dew point boot
集尘器在低于露点运转，简单发作疑问，假如进气散布不均，简单形成除尘器壳体的腐蚀，因此，应避免除尘器作业在凝露点以下，有保温的设备应运用。
The dust collector below the dew point operation, simple attack of doubt, if the air distribution and simple form of corrosion, dust precipitator therefore should avoid dust collector operation in coagulation below dew point, heat preservation equipment should be used.
