焊接煙塵收集裝置，焊接廢氣收集設備濾筒除塵器是一種干式除塵裝置，它適用于捕集細小、干燥非纖維性粉塵。濾筒采用紡織的濾布或非紡織的氈制成，利用纖維織物的過濾作用對含塵氣體進行過濾，當含塵氣體進入濾筒除塵器，顆粒大、比重大的粉塵，由于重力的作用沉降下來落入灰斗，含有細小粉塵的氣體在通過濾料時，粉塵被阻留，使氣體得到凈化。

Welding smoke and dust collection device, welding exhaust gas collection device filter cartridge dust collector is a dry dust removal device, which is suitable for capturing small, dry non fibrous dust. The filter cartridge is made of textile filter cloth or non-woven felt, and uses the filtering effect of fiber fabric to filter the dusty gas. When the dusty gas enters the filter cartridge dust collector, the large and heavy particles of dust settle down and fall into the ash hopper due to gravity. When the gas containing fine dust passes through the filter material, the dust is blocked and the gas is purified.

濾筒除塵器除塵原理

Dust removal principle of filter cartridge dust collector

含塵氣體由進風口進入除塵器箱體內(nèi)，細小塵粒由于濾筒的多種效應作用，被阻止在濾筒外壁。凈化后的氣體通過濾筒經(jīng)箱體出風口排出。隨著使用時間的增長，濾筒表面吸附的粉塵逐漸增多，濾筒的透氣性減弱，除塵器阻力不斷增大。為了保證除塵器的阻力控制在限定的范圍之內(nèi)，由脈沖控制儀發(fā)出信號，循序打開脈沖電磁閥，使氣罐 內(nèi)的壓縮空氣由噴吹管各噴口噴射到對應濾筒，造成濾筒內(nèi)瞬間氣體膨脹，使積聚在濾袋外壁上的粉塵抖落，進入灰斗。

Dust containing gas enters the dust collector box through the air inlet, and small dust particles are blocked on the outer wall of the filter cartridge due to various effects of the filter cartridge. The purified gas is discharged through the outlet of the box through the filter cartridge. As the usage time increases, the amount of dust adsorbed on the surface of the filter cartridge gradually increases, the permeability of the filter cartridge weakens, and the resistance of the dust collector continues to increase. In order to ensure that the resistance of the dust collector is controlled within a limited range, a pulse control instrument sends a signal and sequentially opens the pulse solenoid valve, so that the compressed air in the gas tank is sprayed from each nozzle of the blowing pipe to the corresponding filter cartridge, causing instantaneous gas expansion inside the filter cartridge, causing the dust accumulated on the outer wall of the filter bag to shake off and enter the ash hopper.

濾筒除塵器工藝結(jié)構(gòu)

Process structure of filter cartridge dust collector

濾筒除塵器結(jié)構(gòu)主要由上部箱體、中部箱體、下部箱體（灰斗）、清灰系統(tǒng)和排灰機構(gòu)等部分組成。布袋除塵器性能的好環(huán)，除了正確選擇濾袋材料外，清灰系統(tǒng)對濾筒除塵器起著決定性的作用。

The structure of the filter cartridge dust collector mainly consists of upper box, middle box, lower box (ash hopper), ash cleaning system, and ash discharge mechanism. The performance of a bag filter is not only determined by the correct selection of filter bag materials, but also by the decisive role of the cleaning system in the filter cartridge dust collector.

濾筒除塵器采用垂直式濾筒結(jié)構(gòu)，便于粉塵吸附及清灰；且由于在清灰時濾料的抖動較小，使濾筒的壽命大大高于濾袋，維修費用低。采用目前國際上先進的離線三狀態(tài)（過濾、清灰、靜止）清灰方式，避免了清灰時的“再吸附”現(xiàn)象，使清灰徹底可靠。設計有預收塵機構(gòu)，不但克服了粉塵直接沖刷容易磨損濾筒的缺點，而且可以大大提高除塵器入口處的粉塵濃度。對影響主要性能的關(guān)鍵元件（如脈沖閥）采用進口件，其易損件膜片的使用壽命超過100萬次。采用分列噴吹清灰技術(shù)，一個脈沖閥可同時噴吹一列，可大大地減少脈沖閥的數(shù)量。脈沖閥三狀態(tài)清灰機構(gòu)采用PLC自動控制，并兼有定時或手動二種控制方式任選。單位過濾面積占用的三維空間小，可替用戶節(jié)約大量空間資源，間接減少用戶的一次性投資成本。使用壽命長，濾筒的使用壽命可達1～3年，大大地減少了除塵器更換濾芯的次數(shù)，維護簡單，大大降低了用戶在使用過程中的維護成本。

The filter cartridge dust collector adopts a vertical filter cartridge structure, which is convenient for dust adsorption and cleaning; And due to the small shaking of the filter material during ash cleaning, the service life of the filter cartridge is much longer than that of the filter bag, resulting in low maintenance costs. Adopting the currently advanced offline three-state (filtering, cleaning, and static) cleaning method internationally, it avoids the phenomenon of "re adsorption" during cleaning and ensures complete and reliable cleaning. Designed with a pre dust collection mechanism, it not only overcomes the disadvantage of direct dust erosion and easy wear of the filter cartridge, but also greatly improves the dust concentration at the inlet of the dust collector. The key components that affect the main performance (such as pulse valves) are imported, and the service life of the vulnerable part diaphragm exceeds 1 million times. By using the split jet cleaning technology, one pulse valve can simultaneously spray one column, greatly reducing the number of pulse valves. The pulse valve three state ash cleaning mechanism adopts PLC automatic control, and there are two control modes available: timed or manual. The unit filtering area occupies a small three-dimensional space, which can save users a lot of space resources and indirectly reduce their one-time investment costs. Long service life, the service life of the filter cartridge can reach 1-3 years, greatly reducing the frequency of replacing the filter element of the dust collector, simple maintenance, and greatly reducing the maintenance cost for users during use.

脈沖濾筒除塵器應用得廣泛，固定濾袋用的多孔板（花板）設在除塵器箱體的上部，在每排濾袋的上方有一噴吹管，噴吹管上對著每一濾袋的中心開一壓氣噴射孔（嘴），噴吹管的另一端與脈沖閥、控制閥等組成的脈沖控制系統(tǒng)及壓縮空氣儲氣罐相連接，根據(jù)規(guī)定的時間或阻力值，按自動控制程序進行脈沖噴吹清灰。濾袋通常采用外率式，里面含有骨架作為支撐，粉塵被捕集而沉降在布袋的外表面。清灰時的一瞬間，當高速噴射氣流通過濾袋_時，能誘導幾倍于噴射氣量的空氣，一起吹向濾袋內(nèi)部，形成空氣波，使濾袋由上向下產(chǎn)生急劇的膨脹和沖擊振動，產(chǎn)生很強的清落粉塵的作用。脈沖周期可以調(diào)整，一般為1分鐘到幾分鐘。

Pulse filter cartridge dust collectors are widely used. The porous plate (flower plate) used to fix the filter bag is located at the upper part of the dust collector box, and there is a spray pipe above each row of filter bags. A compressed air injection hole (nozzle) is opened on the spray pipe towards the center of each filter bag. The other end of the spray pipe is connected to a pulse control system composed of pulse valves, control valves, etc. and a compressed air storage tank. According to the specified time or resistance value, pulse spray cleaning is carried out according to the automatic control program. Filter bags are usually of an external rate type, containing a skeleton as support, and dust is captured and settled on the outer surface of the cloth bag. At the moment of dust removal, when the high-speed jet airflow passes through the filter bag, it can induce several times the amount of air sprayed and blow into the inside of the filter bag together, forming air waves, causing the filter bag to rapidly expand and vibrate from top to bottom, producing a strong effect on dust removal. The pulse period can be adjusted, usually from 1 minute to a few minutes.

（1）工作原理：

(1) Working principle:

含塵氣流由下部風口進入氣箱，通過導流擋板將氣流均勻分配至過濾元件，在過濾元件的作用下，煙塵被吸附在過濾元件的表面，潔凈的氣體通過出口管道排出，脈沖閥在控制儀的控制下，對過濾元件進行輪流清灰;由于過濾零件采用垂直安裝方式，可以保證良好的清灰效果。

The dusty airflow enters the air box from the lower air outlet and is evenly distributed to the filtering element through a guide baffle. Under the action of the filtering element, smoke and dust are adsorbed on the surface of the filtering element, and clean gas is discharged through the outlet pipeline. Under the control of the control instrument, the pulse valve alternately cleans the filtering element; Due to the vertical installation method of the filtering components, good dust removal effect can be ensured.

凈化器濾材的清潔通過由脈沖控制儀控制的噴吹裝置實現(xiàn)：

The cleaning of the purifier filter material is achieved through a spray device controlled by a pulse controller:

當凈化器運行一段時間以后，細微的煙塵吸附在濾材表面，使得濾材的透氣性降低。每隔一定時間由脈沖控制儀發(fā)出信號，控制電磁閥，潔凈的壓縮空氣由閥口噴出；濾材表面吸附的微塵在氣流作用下被清除，落在室體下部的集塵斗中。脈沖噴吹需0.4～0.6MPa的潔凈壓縮空氣，且運行中須保持連續(xù)且恒定不變的供氣量。

After the purifier runs for a period of time, fine smoke and dust adsorb on the surface of the filter material, reducing its breathability. At regular intervals, the pulse controller sends out signals to control the solenoid valve, and clean compressed air is sprayed out from the valve port; The fine dust adsorbed on the surface of the filter material is removed by the airflow and falls into the dust collection hopper at the bottom of the chamber. Pulse injection requires clean compressed air of 0.4-0.6 MPa and a continuous and constant gas supply during operation.

（2）濾材介紹：

(2) Introduction to filter materials:

該處理系統(tǒng)采用的濾芯為焊煙專用濾芯，為聚四氟乙烯（PTFE）聚酯濾材，該濾材是一種高科技產(chǎn)品，它的微孔結(jié)構(gòu)可在特殊條件下經(jīng)機械拉伸得到，而絲毫未改變其原有特性。微孔徑可控制在0.2-0.3μm，過濾方法屬于表面過濾。膜表面光滑又具備極佳的化學穩(wěn)定性，能抗腐蝕，耐酸堿、不老化又憎水性。在過濾時膜表面截留的煙塵很容易剝落，其通氣量能長期保持在同一水平上。由于覆膜濾材是用其光滑不粘的表面截留煙塵，利用這一特性不僅可以節(jié)約脈沖清灰系統(tǒng)的壓縮空氣量，又可避免煙塵對薄膜基布的磨損，延長了濾筒的使用壽命，同時為設備提供最低而平穩(wěn)的壓降差。覆膜式濾筒面積大、體積小、降低能量損耗，加大其流量，延長免保養(yǎng)時間，高效覆膜聚酯濾筒是焊接煙塵收集系統(tǒng)的最佳選擇。

The filter element used in this processing system is a welding smoke special filter element, made of polytetrafluoroethylene (PTFE) polyester filter material. This filter material is a high-tech product, and its microporous structure can be obtained through mechanical stretching under special conditions without changing its original characteristics. The micropore diameter can be controlled between 0.2-0.3 μ m. The filtration method belongs to surface filtration. The surface of the membrane is smooth and has excellent chemical stability, which can resist corrosion, acid and alkali, is not aging, and is hydrophobic. The smoke and dust trapped on the membrane surface during filtration are easily peeled off, and its ventilation capacity can be maintained at the same level for a long time. Due to the use of its smooth and non stick surface to retain smoke and dust, the use of this characteristic in membrane filter materials can not only save the compressed air volume of pulse cleaning systems, but also avoid the wear of the film substrate caused by smoke and dust, extend the service life of the filter cartridge, and provide the equipment with the lowest and most stable pressure drop. The membrane covered polyester filter cartridge has a large area, small volume, reduces energy loss, increases its flow rate, prolongs maintenance free time, and is the best choice for welding smoke and dust collection systems with high efficiency.

采用PTFE濾料制成的特制濾筒（聚酯+覆膜），同時具有膜過濾和剛性機體過濾的特點。

A specially designed filter cartridge (polyester+membrane) made of PTFE filter material, which has the characteristics of both membrane filtration and rigid body filtration.

堅固的剛性過濾體能承受較高的工作壓力，不需任何骨架支撐，并承受一定的機械沖擊力，反吹時濾筒不變形。由于除塵器面板采用螺栓緊固易于拆裝，濾筒采用三耳吊裝，因此安裝和更換濾筒極為方便。濾筒過濾器具有以下特點：

The sturdy and rigid filter body can withstand high working pressure without any skeleton support, and can withstand certain mechanical impact forces. The filter cartridge does not deform during reverse blowing. Due to the fact that the dust collector panel is fastened with bolts and easy to disassemble, and the filter cartridge is lifted with three ears, installation and replacement of the filter cartridge are extremely convenient. The filter cartridge filter has the following characteristics:

①煙塵捕集效率高：過濾元件的除塵效率是由其本身特有的結(jié)構(gòu)和涂層來實現(xiàn)的，適用于極細和特殊煙塵，通常對0.3μm以上超細煙塵的除塵效率可達到99.5%。由于焊接、切割煙塵顆粒直徑大部分在0.2μm以上，因此特別適合金屬焊接、切割煙塵的凈化過濾。

① High smoke and dust capture efficiency: The dust removal efficiency of the filter element is achieved by its unique structure and coating, suitable for extremely fine and special smoke and dust, usually up to 0.3 μ The dust removal efficiency of ultra-fine smoke and dust above m can reach 99.5%. Due to welding and cutting, the diameter of smoke particles is mostly 0.2 μ Above m, therefore it is particularly suitable for purifying and filtering metal welding and cutting smoke and dust.

②阻力損失穩(wěn)定：由于濾筒是通過表面的PTFE涂層對煙塵進行捕捉的，其光滑的表面使煙塵很難透過與停留，過濾筒母體層中不會發(fā)生堵塞現(xiàn)象，阻力損失僅與過濾風速有關(guān)。

② Stable resistance loss: Due to the fact that the filter cartridge captures smoke and dust through a PTFE coating on its surface, its smooth surface makes it difficult for smoke and dust to pass through and stay. There is no blockage phenomenon in the mother layer of the filter cartridge, and the resistance loss is only related to the filtering wind speed.

③采用PTFE濾料制成的特制濾筒（聚酯+覆膜），具有阻燃的作用。

③ A specially made filter cartridge made of PTFE filter material (polyester+coated) has a flame retardant effect.

④清灰效果好：濾筒的剛性結(jié)構(gòu)，使得脈沖反吹氣流向空隙噴出時，濾筒無變形，表層粘附的煙塵，在瞬間即可被除去。

④ Good dust removal effect: The rigid structure of the filter cartridge allows for no deformation of the filter cartridge when the pulse back blowing air flows towards the gap, and the adhered smoke and dust on the surface can be instantly removed.

⑤使用壽命可達1～2年，大大減少了更換濾芯的次數(shù)；濾筒的無故障運行時間長，不需要經(jīng)常的維護與保養(yǎng)。

⑤ The service life can reach 1-2 years, greatly reducing the frequency of replacing the filter element; The fault free operation time of the filter cartridge is long and does not require frequent maintenance and upkeep.
