走進(jìn)一個(gè)沒有安裝多工位焊煙除塵系統(tǒng)的焊接車間，幾十個(gè)焊槍同時(shí)作業(yè)，灰色的煙霧彌漫在空氣中，工人們戴著口罩依然嗆得咳嗽。而安裝了集中式系統(tǒng)的車間，空氣清澈如洗，工人們可以摘下口罩安心作業(yè)。這一鮮明對(duì)比的背后，是一套被稱為“車間空氣指揮官”的系統(tǒng)在默默工作。

Entering a welding workshop without a multi station welding smoke and dust removal system, dozens of welding guns were operating simultaneously, and gray smoke permeated the air. The workers were still coughing despite wearing masks. In workshops equipped with centralized systems, the air is as clear as washing, and workers can take off their masks and work with peace of mind. Behind this stark contrast is a system known as the 'Workshop Air Commander' working silently.

多工位焊煙除塵設(shè)備，又稱集中式焊煙除塵器或中央焊煙凈化系統(tǒng)，是針對(duì)焊接工位較多且緊湊、同時(shí)加工多種工序及工況較復(fù)雜的車間環(huán)境治理而設(shè)計(jì)的系統(tǒng)性環(huán)保裝備。它通過中央集塵單元與分布式管道網(wǎng)絡(luò)的結(jié)合，實(shí)現(xiàn)對(duì)多工位焊接作業(yè)產(chǎn)生的煙塵、顆粒物及有害氣體的高效捕集與凈化。一臺(tái)主機(jī)可覆蓋數(shù)十至數(shù)百個(gè)焊接工位，滿足大型制造企業(yè)集中化生產(chǎn)的需求。

Multi station welding smoke dust removal equipment, also known as centralized welding smoke dust collector or central welding smoke purification system, is a systematic environmental protection equipment designed for the treatment of workshop environments with multiple and compact welding stations, multiple processes and complex working conditions. It combines a central dust collection unit with a distributed pipeline network to achieve efficient capture and purification of smoke, particulate matter, and harmful gases generated during multi station welding operations. A single host can cover dozens to hundreds of welding stations, meeting the centralized production needs of large manufacturing enterprises.

多工位焊煙除塵系統(tǒng)的工作原理基于負(fù)壓吸附與過濾分離技術(shù)。系統(tǒng)由過濾單元（除塵器）、大風(fēng)量吸塵風(fēng)機(jī)、排風(fēng)管道、電控系統(tǒng)及相關(guān)配件組成。當(dāng)系統(tǒng)啟動(dòng)后，風(fēng)機(jī)產(chǎn)生負(fù)壓，通過各工位安裝的吸氣臂或吸氣罩將焊接產(chǎn)生的煙塵吸入主管道。根據(jù)固定點(diǎn)位的不同焊接形式（點(diǎn)、線、面等），前端可采用吸氣臂、吸氣罩和房體進(jìn)行收集。含塵氣體經(jīng)主管道進(jìn)入除塵器箱體后，煙塵被濾材高效凈化——焊接煙塵中70%以上為亞微米級(jí)粉塵，濾筒除塵器標(biāo)配PTFE覆膜濾料，對(duì)0.3μm以上粉塵的捕集效率可達(dá)99.9%以上。脈沖閥控制濾材的自動(dòng)清灰功能，每隔一段時(shí)間對(duì)濾材從內(nèi)而外進(jìn)行反吹清灰，沉流式設(shè)計(jì)保證反吹過程中的顆粒物落入集灰桶集中收集。凈化后的達(dá)標(biāo)氣體經(jīng)煙筒外排。

The working principle of the multi station welding smoke dust removal system is based on negative pressure adsorption and filtration separation technology. The system consists of a filtering unit (dust collector), a high air volume suction fan, an exhaust duct, an electronic control system, and related accessories. After the system is started, the fan generates negative pressure, and the smoke and dust generated by welding are sucked into the main pipeline through the suction arms or hoods installed at each workstation. According to the different welding forms of fixed points (points, lines, surfaces, etc.), the front end can be collected using suction arms, suction hoods, and room bodies. After the dusty gas enters the dust collector box through the main pipeline, the smoke and dust are efficiently purified by the filter material - more than 70% of the welding smoke and dust are sub micron level dust. The filter cartridge dust collector is equipped with PTFE coated filter material, and the capture efficiency of dust above 0.3 μ m can reach over 99.9%. The pulse valve controls the automatic dust cleaning function of the filter material, and periodically blows back the filter material from the inside out to clean the dust. The sinking flow design ensures that particles during the back blowing process fall into the dust collection bucket for centralized collection. The purified standard gas is discharged through the chimney.

在工程實(shí)踐中，多工位焊煙除塵系統(tǒng)已廣泛應(yīng)用于汽車制造、重型機(jī)械、軌道交通、能源裝備等行業(yè)。以某汽車工廠焊接車間改造為例，原分散式除塵設(shè)備效率低、車間PM2.5濃度超標(biāo)2倍。部署一套風(fēng)量30,000m?/h的中央式除塵系統(tǒng)覆蓋12個(gè)焊接工位后，煙塵捕集率提升至98%，年運(yùn)維成本降低40%。對(duì)于9工位焊接車間，采用“枝狀管網(wǎng)布局”將主管道沿焊接生產(chǎn)線架空鋪設(shè)，各工位通過電動(dòng)風(fēng)閥聯(lián)動(dòng)控制，每個(gè)工位設(shè)置不同吸風(fēng)量（1200-2000m?/h），通過變頻器動(dòng)態(tài)調(diào)節(jié)總風(fēng)量。一個(gè)主機(jī)管住整個(gè)車間，多工位焊煙除塵設(shè)備正在讓焊接車間告別“煙霧繚繞”的歷史。

In engineering practice, multi station welding smoke and dust removal systems have been widely used in industries such as automobile manufacturing, heavy machinery, rail transit, and energy equipment. Taking the renovation of a welding workshop in a certain automobile factory as an example, the original decentralized dust removal equipment had low efficiency and the PM2.5 concentration in the workshop exceeded the standard by twice. After deploying a central dust removal system with an air volume of 30000 m 3/h to cover 12 welding stations, the smoke and dust capture rate was increased to 98%, and the annual operation and maintenance costs were reduced by 40%. For the 9-station welding workshop, a "branched pipe network layout" is adopted to lay the main pipeline overhead along the welding production line. Each station is controlled by an electric air valve linkage, and different suction air volumes (1200-2000m?/h) are set for each station. The total air volume is dynamically adjusted through a frequency converter. A single host controls the entire workshop, and multi station welding smoke and dust removal equipment is bidding farewell to the history of the welding workshop being shrouded in smoke.
