Spattering rust removing device provided with corrosion-resistant layer

Abstract

The invention discloses a spattering rust removing device provided with a corrosion-resistant layer. The spattering rust removing device mainly comprises a partitioning tank, a spattering rust remover and a control device, wherein an air inlet and a discharge hole are respectively formed in the lower part of the partitioning tank; the air inlet is connected with a sand blasting machine; the bottom inside the partitioning tank is filled with a solvent; a baffle plate is arranged above the solvent; an exhaust tube at the top of the partitioning tank is connected with the spattering rust remover through a flange; a grid plate, a cloth bag dust collection device and a purifier device are arranged from bottom to top inside the spattering rust remover; an exhaust hole is formed in the top of the spattering rust remover; a pollutant detection device is arranged at the top of the spattering rust remover; a slag discharge tube at the bottom of the spattering rust remover is connected with the partitioning tank through a safety valve; the control device is connected with each single channel switch. The spattering rust removing device has a function of synchronous treatment on paint droplets, dust and VOC (volatile organic compounds), treatment effects and pressure can be automatically monitored and adjusted, the VOC treatment rate is greater than 99.5%, and the spattering rust removing device is simple in structure and low in manufacturing and processing cost.

Description

technical field [0001] The invention relates to the field of splash derusting devices provided with an anti-corrosion layer. Background technique [0002] At present, there will be a large amount of paint mist discharged during the painting production process. The main components of the paint mist are paint droplets, dust, and volatile benzene and benzene series and other organic pollutants (volatile benzene and benzene series are referred to as VOC). Cause ambient air pollution, and generally need to be treated and discharged after reaching the standard. The existing spray rust removal methods mainly include isolation method, combustion method, absorption method, condensation method, plasma low-temperature catalytic oxidation method, adsorption method, etc., the existing treatment Most of the devices occupy an increased area, are inconvenient to operate and manage, and have high manufacturing and processing costs, and the treatment effect cannot be effectively monitored; fo...

[0002] At present, there will be a large amount of paint mist discharged during the painting production process. The main components of the paint mist are paint droplets, dust, and volatile benzene and benzene series and other organic pollutants (volatile benzene and benzene series are referred to as VOC). Cause ambient air pollution, and generally need to be treated and discharged after reaching the standard. The existing spray rust removal methods mainly include isolation method, combustion method, absorption method, condensation method, plasma low-temperature catalytic oxidation method, adsorption method, etc., the existing treatment Most of the devices occupy an increased area, are inconvenient to operate and manage, and have high manufacturing and processing costs, and the treatment effect cannot be effectively monitored; for example, the CN201220611438. Rust device: including a settlement pit, filter cotton and a grid plate, the grid plate is arranged at the entrance of the settlement pit, the filter cotton is arranged between the entrance and the exit of the settlement pit, and also includes a labyrinth The paint baffle plate, the labyrinth paint baffle plate is arranged under the grid plate, the labyrinth paint baffle plate and the organic gas adsorption device are added, the treatment effect of the overall oversprayed paint particles is improved, and the organic gas is reduced The device realizes the simultaneous treatment of paint mist and VOC; the disadvantages of this device are: complex structure of equipment, large area and space, high cost of production, maintenance and management of equipment, and when the processing device is abnormal, it cannot Automatic monitoring and automatic switching start backup device
