脉冲布袋除尘器整个设备包含净气箱、尘气箱、灰斗、喷吹设备和支架五个部分。净气箱部，这部本分装有喷吹管，净气部有净气出口，前面是检修门，翻开检修门时，能够很便利地替换任何一条滤袋，尘气部分，尘气   设在气箱部分上部，箱内装有滤袋，灰斗部分，尘气进入尘气箱后，洁净空气空过滤袋去净气箱。尘埃将沉降到灰斗中去，且沉降方向与气流方向一致，有利于尘埃的沉降。净气箱和尘气箱之间有隔板，滤袋尺度为长1200mm，宽480mm，厚26mm的矩形扁滤袋。反吹风设备，装在净气箱下面，包含气包、脉冲阀、脉冲操控仪等。

The entire equipment of the pulse bag filter includes five parts: a clean air box, a dust air box, an ash hopper, a spraying equipment, and a bracket. The air purification box section is equipped with a spray pipe, and the air purification section has a clean air outlet. The front is the maintenance door, and when the maintenance door is opened, it can easily replace any filter bag. The dust and gas section is located in the upper part of the air box section, and the box is equipped with filter bags and an ash hopper section. After the dust and gas enter the dust and gas box, clean air passes through the filter bag and goes to the air purification box. Dust will settle into the ash hopper, and the settling direction is consistent with the airflow direction, which is conducive to the settling of dust. There is a partition between the clean air box and the dust box, and the filter bag size is a rectangular flat filter bag with a length of 1200mm, a width of 480mm, and a thickness of 26mm. Anti blowing equipment, installed under the air purification box, including air pockets, pulse valves, pulse controllers, etc.

脉冲布袋除尘器试作业的好坏，直接影响其是否能投入正常运转，如处理不妥，很可能会很快失掉功效，因而，做好设备的试作业仔细和稳重。在新的脉冲布袋除尘器试运转时，应特别注意查看下列各点：

The quality of the trial operation of the pulse bag filter directly affects whether it can be put into normal operation. If not handled properly, it is likely to quickly lose its effectiveness. Therefore, it is important to carefully and steadily carry out the trial operation of the equipment. During the trial operation of the new pulse bag filter, special attention should be paid to checking the following points:

1、风机的旋转方向、转速、轴承振荡和温度。

1. The rotation direction, speed, bearing oscillation, and temperature of the fan.

2、处理风量和各测试点压力与温度是否与设计相符。

2. Check if the air volume and pressure and temperature at each testing point match the design.

3、滤袋的设备情况，在运用后是否有掉袋、松口、磨损等情况发作，投运后可目测烟囱的排放情况来判别。

3. The equipment condition of the filter bag can be determined by visually observing the emission situation of the chimney after operation to determine whether there is any bag dropping, loosening, or wear and tear.

4、要注意袋室结露情况是否存在，排灰体系是否疏通。避免阻塞和腐蚀发作，积灰严峻时会影响主机的出产。

4. Pay attention to whether there is condensation in the bag room and whether the ash discharge system is unobstructed. Avoid blockages and corrosion, as severe dust accumulation can affect the production of the host.

5、清灰周期及清灰时刻的调整，这项作业是左右捕尘性能和作业情况的重要因素。清灰时刻过长，将使附着粉尘层被清落掉，成为滤袋泄漏和破损的原因。如果清灰时刻过短，滤袋上的粉尘没有清落掉，就   过滤作业，将使阻力很快地   并逐步起来，影响其运用效果。

5. The adjustment of the cleaning cycle and cleaning time is an important factor affecting the dust capture performance and operation situation. If the cleaning time is too long, it will cause the attached dust layer to be removed, becoming the cause of filter bag leakage and damage. If the cleaning time is too short and the dust on the filter bag is not removed, the filtering operation will quickly and gradually increase the resistance, affecting its application effect.

脉冲布袋除尘器的几项特色

Several characteristics of pulse bag filter

1、选用淹没式脉冲阀，启闭敏捷，本身阻力小，对于6米～8米长的滤袋，喷吹压力仅0.15～0.3MPa，就能取得杰出的清灰效果。

1. Using a submerged pulse valve, it has agile opening and closing, low resistance, and can achieve outstanding cleaning effect for 6-8 meter long filter bags with a spraying pressure of only 0.15-0.3 MPa.

2、清灰。清灰时滤袋外表取得的加速度远远大于其它类型的脉冲布袋除尘器，清灰均匀，效果好。

2. Clear the dust. The acceleration achieved on the surface of the filter bag during dust removal is much greater than that of other types of pulse bag dust collectors, resulting in uniform dust removal and good results.

3、过滤负荷高。因有清灰的，即使除尘器在较高的过滤风速下运转，其阻力也不会过高，一般为1200～1500Pa，与反吹风除尘器比较，平等过滤面积，脉冲布袋除尘器有较大的处理风量。

3. High filtration load. Due to the presence of dust removal, even if the dust collector operates at a higher filtering wind speed, its resistance will not be too high, generally between 1200-1500Pa. Compared with the back blowing dust collector, the pulse bag dust collector has an equal filtering area and a larger processing air volume.

4、查看和替换滤袋便利。滤袋的设备和换袋便利，无需绑扎。操作人员无需进入箱体内部，操作环境好。

4. Convenient to view and replace filter bags. The equipment and bag replacement of the filter bag are convenient, without the need for tying. Operators do not need to enter the interior of the box, and the operating environment is good.

5、设备造价低。因为过滤负荷高，处理相同烟气量所需过滤面积小于反吹风脉冲布袋除尘器，因而设备紧凑，占地面积小。

5. The equipment cost is low. Due to the high filtration load, the required filtration area for processing the same amount of flue gas is smaller than that of the reverse blowing pulse bag filter, resulting in compact equipment and small footprint.

6、   的操控技能。以PLC可编程操控器为主机的操控体系对除尘器清灰、   烟气温度、清灰压力等运转参数进行实时操控，功用，稳定。

6. Control skills. The control system with PLC programmable controller as the main host can control the real-time operation parameters of the dust collector, such as dust removal, flue gas temperature, and dust removal pressure, with stable and functional performance.

脉冲布袋除尘器在很久以前便已有运用，在一些发达   像是燃煤电站的运用已经有二三十年的前史，在我国布袋除尘器被广泛的运用于炼铁厂、炼钢厂、铁合金厂、耐火厂、铸造厂、发电厂等的场所。早在20世纪80年代初燃煤电站锅炉上尝试运用布袋除尘器，现在我国布袋除尘器的研讨越来越   ，清灰效果越来越显着。并且还会有用的除掉烟气中的粉尘。

Pulse bag filter has been in use for a long time, and has a history of 20-30 years in some developed coal-fired power plants. In China, bag filter is widely used in iron and steel plants, ferroalloy plants, refractory plants, casting plants, power plants, and other fields. As early as the early 1980s, attempts were made to use bag filters on coal-fired power plant boilers. Now, there is increasing research on bag filters in China, and the cleaning effect is becoming more and more significant. And it will also effectively remove dust from the smoke.
