Welding fume purifier

Welding fume purifier

Yuehua Chaohua Welding fume purifier is used for the purification of fume and dust generated in welding, cutting, grinding and other processes, as well as the recovery of rare metals, precious materials, etc. It can purify a large number of fine metal particles suspended in the air that are harmful to human body. It is characterized by high purification efficiency, low noise, flexible use and small footprint. It is suitable for the operation places where fumes are generated such as handlebar welding, electric arc welding, carbon dioxide protection welding, MAG welding, carbon arc gas planing welding, gas fusion cutting, special welding and so on. The main parts of the equipment include: universal dust-absorbing arm, high-temperature resistant dust-absorbing hose, dust-absorbing hood (with airflow regulating valve), fire-retardant net, flame-retardant high-efficiency cartridge, casters with brakes, blower, Huali motor, and pulse solenoid valve.Look forward to your consultation. 

Prospects of production: The application of welded structures is increasing due to their advantages of light weight, low cost, stable quality, short production cycle, high efficiency and fast market response.

Welding fume purifier structure composition：

The main components include: universal dust suction arm, high temperature resistant dust suction hose, dust suction hood (with airflow regulating valve), fire retardant mesh, flame retardant high efficiency filter element, dust sinking drawer combination, casters with brakes, blower, motor and so on.

Management of smoke and dust:Welding fumes, also known as welding smoke, refers to some toxic substances that are often produced during welding operations. Such as: acetaldehyde, rosin acid, isocyanates, nitrogen oxides, sulfides, hydrocarbons, etc. Welding fume is a very complex substance. Lans has found more than 20 elements in the fume, among which the most abundant elements are Fe, Ca, Na, etc., followed by Si, Al, Mn, Ti, Cu, etc.

The main harmful substances in welding fume are Fe2O3, SiO2, MnO, HF, etc., of which the most abundant is Fe2O3, which generally accounts for 35.56% of the total amount of fume, followed by SiO2, the content of which accounts for 10-20%, and MnO, which accounts for about 5-20%.

Welding fume control technology: welding process produces a variety of pollution, hazardous, will lead to a variety of occupational diseases (such as silicosis, manganese poisoning, electro-optical ophthalmia, etc.), has become a major environmental nuisance. With the deepening of the relevant research, treatment technology is becoming more and more perfect, welding pollution has been relatively effective control. Welding process pollution is serious, the environment and welders cause very great harm, for fume control, should be from the source of pollution, governance pathways and personal protection in three aspects.

Welding fumes are managed in a number of ways, of which there are three main ones:

1、Process

(1) The use of fume-free and less fume welding process

(2) Development and use of low-dust and low-toxicity welding materials

(3) Improve the degree of mechanization and automation of welding

2. Adopt effective measures for ventilation and smoke removal and purification.

3. Personal protection

Prevent welding fumes from harming operators, prevent fumes from being directly inhaled into human lungs, welders need to wear masks, special welding stations or in closed places should also wear gas masks. Workshop is equipped with welding auxiliary device occasions, to have self-protection awareness, try to use automated welding process and mechanized devices to complete the welding work, so that operators away from the fume gathering area.

Equipment introduction: Welding smoke purifier, also known as metal welding purification equipment, also known as electric welding smoke purifier. The main products include cutting platform purifiers, metal welding and grinding workrooms, metal welding and grinding workbenches, split welding purification workbenches, central welding fume purifiers, mobile welding fume purifiers and other series of purification equipment, which are targeted at mechanical processing plants. It is a lightweight and efficient dust collector designed to deal with the smoke, dust and oil mist generated during welding operations in automobile assembly plants, maintenance plants and related industries.

Mobile welding fume purifier is especially suitable for electric arc welding, carbon dioxide shielded welding, MAG welding, carbon arc gas planing welding, gas fusion cutting, special welding and other workplaces that generate fumes. In the welding operation often produces some toxic substances. Such as: acetaldehyde, rosin acid, isocyanates, nitrogen oxides, sulfides, hydrocarbons, etc.. And in the dispersion in the air. Through the respiratory tract invaded into the human liver, lungs, cardiovascular and blood. These toxic substances are seriously devouring human health. Leading to the emergence of many occupational diseases.Mobile welding fume purifier is especially suitable for electric arc welding, carbon dioxide shielded welding, MAG welding, carbon arc gas planing welding, gas fusion cutting, special welding and other workplaces that generate fumes.

Leading to the emergence of many occupational diseases.Such as: lung cancer, asthma, eczema, bronchitis, skin allergies, respiratory tract infections, etc., or serious disruption of the central nervous system, damage to the digestive system, leading to complications and death by failure.

Equipment role: welding fume purifier is a purification device designed for industrial welding fume and light particles, lightweight and flexible, easy to operate, while widely used in chemical, electronics, metal processing, tobacco, glass, pharmaceutical, food processing, clean room, hospitals, and other industries and other places with dust, smoke pollution.

Metal in industrial welding or other processing treatment process will produce a variety of toxic and harmful gases, welding fume purifier, the nature of the gas in the smoke and processing characteristics, we will be experimental, in order to protect will not produce secondary pollution, does not affect the operation of the workshop, does not affect the life of the equipment under the premise of the use of multi-stage purification devices, the welding smoke exhaust purification treatment, not only to effectively remove the welding fume exhaust, but also degradation of the Welding smoke tar flavor and various toxic and harmful gases.

Application places: mobile welding dust purifier can be widely used in tobacco, medicine, food processing, building materials, metallurgy, chemical industry, electric power, machinery manufacturing, cast iron and other industries for dust removal, material recovery and air filtration.

Working principle: through the fan gravity effect, welding smoke exhaust gas through the universal dust suction hood sucked into the equipment inlet, the equipment inlet is equipped with a flame arrester, sparks by the flame arrester is blocked, soot gas into the settlement chamber, the use of gravity and upward airflow, first of all, the coarse particles of dust directly down to the hopper, particles of soot by the cartridge captured on the outside surface, the clean gas filtered by the cartridge purification, the center of the cartridge flow into the clean room, clean air and The clean air is further purified by activated carbon filter adsorption and then discharged through the air outlet to meet the standard.
