A treatment system for vocs process waste gas in packaging and printing industry

Abstract

The invention relates to the field of waste gas processing, in particular to a VOCs process waste gas treatment system for packaging printing industry. The system comprises a box body, a vibration mechanism, a filtering mechanism, a dust collecting mechanism, a pad plate, a gas inlet and outlet mechanism and a sliding mechanism, wherein athe vibration mechanism is arranged inside the box body; after dust-containing gas enters the inside of the box body from an inlet, a motor is connected with a power supply to realize the operation of driving thea fixing frame to rotate after the motor rotation; one side surface of the fixing frame is of a V-shaped structure; after the fixing frame rotates, the rotation of a convex post parallel to one side surface of the fixing frame is realized; further,after the convex post rotation, the circumference fluctuation of thea fixing plate is realized; the circumference fluctuation on four pistons by a connecting shaft is realized; the circumference fluctuation of thea top plate is finally realized for shaking a cloth bag; the defect of rubber pad aging and vibration plate abrasion due to conventional eccentric wheel rotation heating can be overcome.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a treatment system for waste gas of VOCs process in packaging and printing industry. Background technique [0002] It refers to organic compounds with saturated vapor pressure greater than 133.32Pa at normal temperature and boiling point below 50-260°C at normal pressure, or any organic solid or liquid that can volatilize at normal temperature and pressure. According to its chemical structure, VOC can be further divided into : Alkanes, aromatic hydrocarbons, esters, aldehydes and others. More than 300 species have been identified so far. The most common are benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate (TDI), diisocyanatotoluene, etc. [0003] However, the traditional packaging and printing industry VOCs process waste gas treatment equipment connects the gas to the inside of the filter device for filtration when treating the p...

Problems solved by technology

[0003] However, the traditional packaging and printing industry VOCs process waste gas treatment equipment connects the gas to the inside of the filter device for filtering when treating the printing industry VOCs process waste gas. When filtering, the dust in the bag is driven by clicking to drive the eccentric wheel to vibrate The plate vibrates, and the vibrating plate is beaten for a long time to make the vibrating plate heat and cause the rubber plate to age, reducing the service life of the rubber plate, and using the eccentric wheel to beat the vibrating plate for a long time will easily cause the vibration plate to be worn out.
