Splashing rust removing device with active carbon

Abstract

The invention discloses a splashing rust removing device with active carbon. The splashing rust removing device is mainly composed of an insulating tank, splashing rust removers and a control device. An air inlet and a material discharging opening are formed in the lower portion of the insulating tank respectively, the air inlet is connected with a sand blasting machine, the internal bottom of the insulating tank is filled with a solvent, a baffle plate is arranged above the solvent, an air discharging pipe at the top of the insulating tank is connected with the splashing rust removers through a flange, grid plates, cloth bag dust removing devices and purifier devices are arranged in the splashing rust removers from bottom to top, an air discharging opening and a pollutant detection device are arranged at the top of the splashing rust removing device, slag discharging pipes at the bottoms of the splashing rust removers are connected with the insulating tank through safety valves, and a control device is connected with all single channel switches. The splashing rust removing device has the paint drop, dust and VOC synchronous treating function, the treating effect and pressure can be automatically monitored and adjusted, the VOC treating rate is larger than 99.5%, the device is simple in structure, and the processing cost is low.

Description

technical field [0001] The invention belongs to the environmental protection treatment technology of spray paint waste gas, in particular to a splash rust removal device with activated carbon. 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...

[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, CN201220611438.X patent discloses a spray rust removal device with activated carbon in a dry spray booth : Including settlement pit, filter cotton and grid plate, described grid plate is arranged at the entrance of described settlement pit, and described filter cotton is arranged between the entrance and the outlet of described settlement pit, also includes labyrinth type retaining paint plate, the labyrinth paint baffle is arranged under the grid plate, and a labyrinth paint baffle and an organic gas adsorption device are added to improve the treatment effect of the overall oversprayed paint particles and reduce the emission of organic gases , the device realizes simultaneous treatment of paint mist and VOC; the disadvantages of this device are: complex structure of equipment, large footprint and space, high cost of production, maintenance and management of equipment, and when the processing device is abnormal, it cannot automatically monitor and automatic switchover to boot backup
