In order not to affect the welding process and at the same time to effectively capture the welding fume, according to the characteristics that both heat and pollutants are generated in the welding workshop, and the density of welding fume is less than that of air, the principle of rapid rise of welding fume should be used, and the airflow structure of side blowing and top ventilation should be used. form, in order to achieve the purpose of overall dust removal.
Air supply vents are installed at a height of 5 meters on both sides of the workshop, and fresh air (outdoor fresh air) is supplied with large air volume and low wind speed. The dust-laden gas at the top enters the high-efficiency filter cartridge
Dust Collector through the exhaust port and the exhaust pipe, and the gas that meets the standard after the high-efficiency filtration of the welding fume is discharged to the outdoor or circulated indoors through the exhaust pipe.
Because the capture of smoke and dust is not directly aimed at the smoke-producing part, the dust removal system is not affected by the size of the welding workpiece or the change of the welding station; the high-efficiency filter is adopted, and the filtration accuracy fully meets the indoor emission standard, effectively improving the working area environment; It can effectively solve the problem of smoke and dust purification, and will not cause secondary pollution to the atmosphere; the required air volume is only half of the traditional mixed air supply form, and the operating energy consumption is greatly reduced; because the smoke and dust can meet the indoor emission standards after being filtered, the indoor air can be circulated, Avoid the waste of indoor cooling/heat energy caused by direct exhaust; the dust removal system is not affected by the operator's usage habits, and the operator is not disturbed by the dust removal system during the work process, improving production efficiency.
◆ Scope of application ◆
Welding workshop, the size of the welding workpiece is not fixed, the welding station is not fixed, and there are many welding methods;
◆ Working Principle ◆
The fresh air replacement purification system in the welding workshop is composed of the top suction port and return air duct, filter cartridge dust collector and fan, regulating valve, outdoor exhaust duct, air outlet and duct in the middle of the workshop, bottom air outlet and air supply duct and fresh air fan etc. composition. It is a governance method that can effectively control the spread of pollution sources.
