焊煙除塵設備的基本原理

The basic principle of welding smoke dust removal equipment

　　焊煙除塵器，又稱焊煙吸塵器，是通過濾凈化方式將電焊、保護焊、氬弧焊等燒焊過程中產生的廢渣、有毒有害氣體吸收吸收和處理的設備，通過焊煙除塵器可防止氣體污染，減少有害物質對操作工人的健康侵害，防止職業病，主要是電焊塵肺等的發生。

Welding smoke dust collector, also known as welding smoke vacuum cleaner, is a device that absorbs and processes waste residue, toxic and harmful gases generated during welding, protective welding, argon arc welding, and other welding processes through filtration and purification. Through welding smoke dust collector, gas pollution can be prevented, harmful substances can be reduced to the health of operators, and occupational diseases, mainly welding pneumoconiosis, can be prevented.

Structural composition

　　主要部件包括：萬向吸塵臂、耐高溫吸塵軟管、吸塵罩（帶風量調節閥）、阻火網、阻燃高效濾芯、脈沖反吹裝置、脈沖電磁閥、壓差表、潔凈室、活性碳過濾器、沉灰抽屜組合、阻燃吸音棉、帶剎車的新韓式腳輪、風機以及電控箱等。

The main components include: universal vacuum arm, high-temperature resistant vacuum hose, vacuum hood (with air volume control valve), flame retardant mesh, flame-retardant and high-efficiency filter element, pulse backwash device, pulse solenoid valve, pressure differential gauge, clean room, activated carbon filter, ash drawer combination, flame-retardant sound absorbing cotton, new Korean style casters with brakes, fan, and electrical control box.

　　通過風機引力作用，焊煙廢氣經萬向吸塵罩吸入設備進風口，設備進風口處設有阻火器，火花經阻火器被阻留，煙塵氣體進入沉降室，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，潔凈氣體經濾芯過濾凈化后，由濾芯中心流入潔凈室，潔凈空氣又經活性碳過濾器吸附進一步凈化后經出風口達標排出。

Through the gravitational force of the fan, the welding smoke exhaust gas is sucked into the equipment inlet through the universal vacuum hood. A flame arrester is installed at the equipment inlet, and sparks are blocked by the flame arrester. The smoke and dust gas enters the settling chamber. By using gravity and upward airflow, the coarse dust is first directly lowered to the ash hopper, and 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. The clean air is further purified by the activated carbon filter and discharged after reaching the standard through the outlet.
