走進一個沒有安裝旱煙除塵器的焊接車間，刺鼻的煙味撲面而來，空氣中彌漫著灰色的煙霧，工人的口罩很快就被熏黑。焊接過程中產(chǎn)生的煙塵含有大量微細金屬顆粒和有害氣體，長期吸入會嚴重危害工人健康。旱煙除塵器正是守護焊接工人呼吸健康的“呼吸守護者”。

Walking into a welding workshop without a dry smoke dust collector installed, a pungent smoke smell hit the face, and gray smoke filled the air. The workers' masks were quickly smoked black. The smoke and dust generated during the welding process contain a large amount of fine metal particles and harmful gases, which can seriously harm the health of workers if inhaled for a long time. The dry smoke dust collector is the "respiratory guardian" that protects the respiratory health of welding workers.

旱煙除塵器，又稱焊煙凈化器或電焊煙塵凈化器，是一種專門用于收集和凈化焊接、切割、打磨等過程中產(chǎn)生的煙塵的工業(yè)環(huán)保設備。其工作原理基于多種除塵機制的協(xié)同作用。當含塵氣流進入除塵器后，首先通過導流裝置被引導至特定區(qū)域。較大的煙塵顆粒因慣性作用無法隨氣流改變方向，會撞擊到擋板上，失去動能后下落至集塵斗——這一過程稱為慣性除塵。對于較小的顆粒（通常直徑在10微米以下），則通過濾筒或濾袋的攔截作用加以捕集。

Dry smoke dust collector, also known as welding smoke purifier or welding smoke purifier, is an industrial environmental protection equipment specifically used to collect and purify the smoke and dust generated during welding, cutting, polishing and other processes. Its working principle is based on the synergistic effect of multiple dust removal mechanisms. When the dusty airflow enters the dust collector, it is first guided to a specific area through a guiding device. Larger smoke particles cannot change direction with the airflow due to inertia, and will collide with the baffle, lose kinetic energy, and fall into the dust collector - this process is called inertial dust removal. For smaller particles (usually with a diameter of less than 10 microns), they are captured by the interception effect of filter cartridges or filter bags.

以濾筒除塵器為例，含旱煙粉塵的氣體在風機引力作用下被吸入除塵器內(nèi)部。進風口處設有阻火器，可有效阻留焊接火花。煙塵氣體進入沉降室后，利用重力與上行氣流，首先將粗粒塵直接降至灰斗，微粒煙塵被濾芯捕集在外表面。潔凈氣體經(jīng)濾芯過濾凈化后，由濾芯中心流入潔凈室，潔凈空氣又經(jīng)活性碳過濾器吸附進一步凈化后經(jīng)出風口達標排放。濾筒采用聚酯、PTFE或納米纖維材料，過濾效率可高達99%以上。部分設備還設計了二級過濾——一級為大顆?；鹦堑倪^濾，二級為細小粉塵的過濾。

Taking the filter cartridge dust collector as an example, the gas containing dry smoke dust is sucked into the interior of the dust collector under the gravitational force of the fan. There is a flame arrester installed at the air inlet, which can effectively block welding sparks. After entering the settling chamber, the smoke and dust gas utilizes gravity and upward airflow to first directly lower the coarse dust into the ash hopper, while the fine smoke and dust are captured on the outer surface by the filter element. After being filtered and purified by the filter element, the clean gas flows into the clean room from the center of the filter element, and the clean air is further purified by adsorption through the activated carbon filter before being discharged through the air outlet to meet the standard. The filter cartridge is made of polyester, PTFE or nanofiber materials, and the filtration efficiency can reach over 99%. Some devices are also designed with secondary filtration - the first stage is for filtering large particles of Mars, and the second stage is for filtering small dust.

從產(chǎn)品類型來看，旱煙除塵器主要分為移動式和集中式兩大類。移動式旱煙除塵器具有可移動性，吸氣臂可360度任意旋轉(zhuǎn)，能隨時懸停并固定，可根據(jù)作業(yè)位置靈活調(diào)整。集中式旱煙除塵器則通常用于大型工廠或車間，可同時處理多個作業(yè)點產(chǎn)生的煙塵。焊接煙塵凈化機由凈化器、吸氣臂和吸氣罩組成，凈化器一般分上中下三箱體。無論是移動式還是集中式，旱煙除塵器都在用科技的力量守護著每一位焊接工人的呼吸健康。

From the perspective of product types, dry smoke dust collectors are mainly divided into two categories: mobile and centralized. The mobile dry smoke dust collector has mobility, and the suction arm can rotate 360 degrees freely, hover and fix at any time, and can be flexibly adjusted according to the working position. Centralized dry smoke dust collectors are usually used in large factories or workshops, which can simultaneously process smoke and dust generated by multiple operating points. The welding fume purifier consists of a purifier, a suction arm, and a suction hood. The purifier is generally divided into three boxes: upper, middle, and lower. Whether mobile or centralized, dry smoke dust collectors are using the power of technology to safeguard the respiratory health of every welding worker.
