Intelligent purification system for large-scale factory building welding smoke haze

Abstract

The invention relates to an intelligent purification system for large-scale factory building welding smoke haze. The intelligent purification system comprises an air supply device arranged in a factory building. The intelligent purification system is characterized in that the air supply device is arranged on the periphery of the lower portion of the factory building, an exhaust hood and an exhaust duct communicated with the exhaust hood are arranged at the top of the factory building, the exhaust duct penetrates a wall on the upper portion of the factory building and is connected with an induced draft fan and a dust collector, the induced draft fan and the dust collector are arranged outside the factory building, at least one smoke haze detection sensor is arranged on the exhaust hood, the air supply device comprises a shell, an intelligent motor, a fan, a filter, a jet air supply outlet A and a horizontal air supply outlet B, the intelligent motor is arranged in the shell, the jet air supply outlet A is formed in the upper portion of the shell, and the horizontal air supply outlet B is formed in the side of the shell. The intelligent purification system is simple in structure, convenient to maintain, fine in exhaust, ventilation and purification effects and fine in energy-saving effect and makes a contribution to developing the economy, protecting environments and treating haze Pm2.5, and the intelligent motor can control air supply and exhaust quantity according to practical situations.

Description

technical field [0001] The invention belongs to the technical field of ventilation equipment, in particular to an intelligent purification system for welding smoke and haze in a large factory building. Background technique [0002] Generally, a factory building over 8 meters is called a tall industrial factory building. A large amount of smoke and haze will be generated during welding in this kind of tall industrial factory building. Due to the height of the factory building, the smoke and haze are not easy to get rid of. The existing welding fume purification methods generally use local ventilation or There are two methods of comprehensive ventilation, and the economic and technical effect of local ventilation and dust removal is better. However, in many cases, due to the limitation of production process layout and operating conditions, local ventilation cannot be set, and only comprehensive ventilation can be used. Due to the large space, this traditional The traditional v...

[0002] Generally, a factory building over 8 meters is called a tall industrial factory building. A large amount of smoke and haze will be generated during welding in this kind of tall industrial factory building. Due to the height of the factory building, the smoke and haze are not easy to get rid of. The existing welding fume purification methods generally use local ventilation or There are two methods of comprehensive ventilation, and the economic and technical effect of local ventilation and dust removal is better. However, in many cases, due to the limitation of production process layout and operating conditions, local ventilation cannot be set, and only comprehensive ventilation can be used. Due to the large space, this traditional The traditional ventilation method has the disadvantages of large ventilation volume, high power consumption, and high operating costs. Moreover, the effect of ventilation and dust removal is often poor, and the smoke and dust are directly discharged into the atmosphere, causing environmental pollution.

[0003] In addition, some existing ventilation systems still have a relatively simple control process, which only relies on manual adjustment, without intelligent control, and consumes a lot of energy.
