Abstract

The invention discloses a paint spraying processing device for water paint VOC gas. The paint spraying processing device for the water paint VOC gas comprises a water trough and a spraying device, an air blowing chamber is arranged above the water trough, the spraying device is arranged between the air blowing chamber and a water trough, the spraying device comprises a water screen plate and a water shower nozzle arranged on the top of the water screen plate, a water mist suction inlet is formed in the water screen plate, the water mist suction inlet is communicated to the two sides of the water screen plate, a water mist chamber is arranged on one side of the water screen plate, an atomization nozzle is arranged in the water mist chamber, an air blowing and paint spraying area is arranged on one side, departing from the water mist chamber, of the water screen plate, an air blowing screen is arranged on the top of the air blowing and paint spraying area, and the air blowing screen is arranged on the air blowing chamber. According to the paint spraying processing device for the water paint containing the VOC gas, most paint mist and VOC gas generated when water paint is sprayed are absorbed through a water screen, residual small amount of the paint mist and the VOC gas can be fully absorbed through the water mist in the water mist chamber, and the paint mist and the VOC gas generated when the water paint is sprayed can be absorbed completely, harmlessness of water paint products is guaranteed, and the safety of the products is improved.

Description

technical field [0001] The invention relates to a treatment device for organic compounds, in particular to a paint spraying treatment equipment for water-based paint VOC gas. Background technique [0002] Plastic paints are widely used in people's daily life, such as ABS, PVC, PS / HIPS, PC, PP and other engineering plastics are widely used in televisions, air conditioners, drinking fountains, mobile phones, motorcycles, electric vehicles, helmets, toys and other industries In practical application, these plastic parts need to undergo secondary processing, that is, coating to make the surface of the object more beautiful and the surface color more durable. Surface defects, plastic paint plays a decorative and protective role on plastic parts. [0003] At present, the industrial coating of plastic parts mainly uses traditional solvent-based paints. Plastic paint is sprayed on plastic parts. The utilization rate of paint varies from workpiece shape and coating process. The effe...
