脈沖布袋除塵器整個設備包含凈氣箱、塵氣箱、灰斗、噴吹設備和支架五個部分。凈氣箱部，這部本分裝有噴吹管，凈氣部有凈氣出口，前面是檢修門，翻開檢修門時，能夠很便利地替換任何一條濾袋，塵氣部分，塵氣   設在氣箱部分上部，箱內裝有濾袋，灰斗部分，塵氣進入塵氣箱后，潔凈空氣空過濾袋去凈氣箱。塵埃將沉降到灰斗中去，且沉降方向與氣流方向一致，有利于塵埃的沉降。凈氣箱和塵氣箱之間有隔板，濾袋尺度為長1200mm，寬480mm，厚26mm的矩形扁濾袋。反吹風設備，裝在凈氣箱下面，包含氣包、脈沖閥、脈沖操控儀等。

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.

脈沖布袋除塵器試作業(yè)的好壞，直接影響其是否能投入正常運轉，如處理不妥，很可能會很快失掉功效，因而，做好設備的試作業(yè)仔細和穩(wěn)重。在新的脈沖布袋除塵器試運轉時，應特別注意查看下列各點：

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、風機的旋轉方向、轉速、軸承振蕩和溫度。

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

2、處理風量和各測試點壓力與溫度是否與設計相符。

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

3、濾袋的設備情況，在運用后是否有掉袋、松口、磨損等情況發(fā)作，投運后可目測煙囪的排放情況來判別。

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、要注意袋室結露情況是否存在，排灰體系是否疏通。避免阻塞和腐蝕發(fā)作，積灰嚴峻時會影響主機的出產。

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、清灰周期及清灰時刻的調整，這項作業(yè)是左右捕塵性能和作業(yè)情況的重要因素。清灰時刻過長，將使附著粉塵層被清落掉，成為濾袋泄漏和破損的原因。如果清灰時刻過短，濾袋上的粉塵沒有清落掉，就   過濾作業(yè)，將使阻力很快地   并逐步起來，影響其運用效果。

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.

脈沖布袋除塵器的幾項特色

Several characteristics of pulse bag filter

1、選用淹沒式脈沖閥，啟閉敏捷，本身阻力小，對于6米～8米長的濾袋，噴吹壓力僅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。清灰時濾袋外表取得的加速度遠遠大于其它類型的脈沖布袋除塵器，清灰均勻，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、過濾負荷高。因有清灰的，即使除塵器在較高的過濾風速下運轉，其阻力也不會過高，一般為1200～1500Pa，與反吹風除塵器比較，平等過濾面積，脈沖布袋除塵器有較大的處理風量。

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、查看和替換濾袋便利。濾袋的設備和換袋便利，無需綁扎。操作人員無需進入箱體內部，操作環(huán)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、設備造價低。因為過濾負荷高，處理相同煙氣量所需過濾面積小于反吹風脈沖布袋除塵器，因而設備緊湊，占地面積小。

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可編程操控器為主機的操控體系對除塵器清灰、   煙氣溫度、清灰壓力等運轉參數(shù)進行實時操控，功用，穩(wěn)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.

脈沖布袋除塵器在很久以前便已有運用，在一些發(fā)達   像是燃煤電站的運用已經有二三十年的前史，在我國布袋除塵器被廣泛的運用于煉鐵廠、煉鋼廠、鐵合金廠、耐火廠、鑄造廠、發(fā)電廠等的場所。早在20世紀80年代初燃煤電站鍋爐上嘗試運用布袋除塵器，現(xiàn)在我國布袋除塵器的研討越來越   ，清灰效果越來越顯著。并且還會有用的除掉煙氣中的粉塵。

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.
