The multi station welding smoke purifier system in the workshop is designed according to the site, and the process flow of the multi station welding smoke purifier is based on the layout of the welding positions in the workshop. Each welding position is separated by a partition into a small space of 2 meters. A conical smoke exhaust hood is installed at the top, and a 7-shaped 400mmx400mm white iron pipe is laid 3.5 meters above the welding position. The pipe hook and strand are each 12 meters long. One is fixed on the room column in the east-west direction, and the other is fixed with a door shaped bracket in the north-south direction. According to the opening of the welding position, a flexible arm with a diameter of 160mm is used to connect the smoke exhaust hood. The flexible arm is used for smoke and dust capture. A medium pressure, 10000m3/h (left and right) variable frequency centrifugal fan is connected through the pipe, and 600mm in front of the fan inlet is Set up a cross-sectional plug for adjusting the air volume, and automatically convert the motor frequency according to the adjusted air volume. The outlet pipeline of the fan is a square tube or cylinder with a diameter of 600mm. The smoke and dust generated during welding are captured by a flexible arm and enter the pipeline. After being treated by a centrifugal fan, the smoke and dust meet the standard and are discharged outside. The height of the exhaust chimney is 500mm higher than the height of the building. This solution requires minimal one-time investment and simple daily maintenance. By using a variable frequency motor, it solves the problem of high energy consumption.

?   The dust collection part of the central smoke and dust purification equipment is designed as a pneumatic gate valve control system, and can be equipped with a ton bag hook design according to customer selection, which facilitates the collection and treatment of dust. At the same time, non-standard design and installation of primary settling chambers, cyclone dust removal devices, etc. can be carried out according to requirements.

本設(shè)備在系統(tǒng)主風機的作用下， 含塵氣體從除塵器上部的進風口進入除塵器底部的氣箱內(nèi)進行含塵氣體的預(yù)處理， 然后從底部進入到上箱體的各除塵室內(nèi)； 粒度細、 密度小的塵粒進入濾塵室后，通過布朗擴散和篩濾等組合效應(yīng)，使粉塵吸附在濾料的外表面上，過濾后的干凈氣體透過濾筒進入上箱體的凈氣室由排氣管經(jīng)風機匯集至出風口排出。

Under the action of the main fan in the system, the dust containing gas enters the gas box at the bottom of the dust collector from the inlet at the top of the dust collector for pre-treatment, and then enters each dust removal chamber in the upper box from the bottom; After the dust particles with fine particle size and low density enter the dust filtering chamber, they are adsorbed on the outer surface of the filter material through a combination of Brownian diffusion and screening effects. The filtered clean gas enters the clean air chamber of the upper box through the filter cartridge and is collected by the exhaust pipe through the fan and discharged from the air outlet.

隨著過濾工況持續(xù)，積聚在濾筒外表面上的粉塵將越積越多，相應(yīng)就會增加設(shè)備的運行阻力，阻力隨濾料表面粉塵層厚度的增加而增大。為了保證系統(tǒng)的正常運行，除塵器阻力的上限應(yīng)維持在 1400～1600Pa 范圍內(nèi)，當超過此限定范圍，應(yīng)由 PLC 脈沖自動控制器通過定阻或定時發(fā)出指令進行清灰。

As the filtration process continues, more and more dust will accumulate on the outer surface of the filter cartridge, which will correspondingly increase the operating resistance of the equipment. The resistance increases with the thickness of the dust layer on the surface of the filter material. In order to ensure the normal operation of the system, the upper limit of the dust collector resistance should be maintained within the range of 1400-1600Pa. When this limit is exceeded, the PLC pulse automatic controller should issue instructions for dust cleaning through fixed resistance or timing.

該濾筒除塵器的清灰過程是脈沖控制儀控制脈沖閥的啟閉。當脈沖閥開啟時，氣包內(nèi)的壓縮空氣通過脈沖閥經(jīng)噴吹管上的小孔噴射處一股高速、高壓的引射氣流，從而形成一股相當于引射氣流體積 1～2 倍的誘導(dǎo)缺陷流，一同進入濾筒內(nèi)，使濾筒內(nèi)出現(xiàn)瞬間正壓并產(chǎn)生鼓脹和微動；沉積在濾料上的粉塵脫落，掉入灰斗內(nèi)，灰斗內(nèi)的粉塵通過卸灰閥，連續(xù)排出。如此逐序循環(huán)清灰，此清灰方式不但、還避免了噴吹清灰產(chǎn)生的粉塵二次吸附。

The cleaning process of the filter cartridge dust collector is controlled by a pulse controller to open and close the pulse valve. When the pulse valve is opened, the compressed air in the air bag is sprayed through the small hole on the spray pipe by the pulse valve, forming a high-speed and high-pressure injection airflow, thereby forming an induced defect flow equivalent to 1-2 times the volume of the injection airflow, which enters the filter cartridge together, causing instantaneous positive pressure and bulging and micro motion in the filter cartridge; The dust deposited on the filter material falls off and falls into the ash hopper. The dust in the ash hopper is continuously discharged through the ash discharge valve. This sequential cleaning method not only avoids the secondary adsorption of dust generated by blowing and cleaning, but also eliminates the need for dust removal.
