What is the working principle of the welding smoke dust collector?

Today, we will introduce the working principle of welding fume collector. At present, welding fume dust collector is an effective method to purify welding fume. The core component of welding fume purification is the filter element of the main unit, which uses new nanofibers and has very good air permeability. The filter material itself has filter holes to filter dust contained in the air flowing through the filter element.

Welding fume dust collector, also known as welding fume purifier, is a device that absorbs and processes waste residue and toxic and harmful gases generated during welding processes such as electric welding, shielded welding, and argon arc welding through filtration and purification. The invention can prevent gas pollution, reduce the harm of harmful substances to the health of operators, and prevent occupational diseases, mainly welding pneumoconiosis.

The main components of the welding fume dust collector include: universal suction arm, high-temperature resistant suction hose, suction hood (with air volume control valve), flame-retardant high-efficiency filter element, pulse backflush device, pulse solenoid valve, differential pressure gauge, clean room, activated carbon filter, dust drawer combination, flame-retardant sound-absorbing cotton, new Korean casters with brakes, fans, ABB motors, electric control cabinets, etc.

Therefore, as long as the filter holes of the filter element are small enough, large particles of welding fume can be successfully treated. Large particles of dust will fall directly underneath, while small particles of dust will adhere to the surface of the filter element. Due to the long-term operation of the welding fume dust collector, the dust accumulated on the surface of the filter element will form a layer of dust and block the filter holes. This will not only reduce the air volume, but also directly affect the collection efficiency of the welding fume dust, and even cause great damage to the dust filtration.

Therefore, the filter element of the welding fume collector must be disposed of regularly. The spray device of the welding fume dust collector is equipped with a filter that can remove oil, water, dust and other impurities in the compressed air to ensure the quality of the air supply. Through regular cleaning, the normal service life of the filter element can be extended to 12 to 18 months, which can save considerable maintenance costs from a cost perspective.
