Environment-friendly splashing derusting device

Abstract

The invention discloses an environment-friendly splashing derusting device mainly composed of an isolation tank, a splashing derusting device and a control device; the lower part of the isolation tank is provided with a gas inlet and a discharge outlet; the gas inlet is connected with a sandblasting machine; the bottom of the interior of the isolation tank is filled with a solvent; a baffling plate is arranged above the solvent; an exhaust pipe at the top of the isolation tank is connected with the splashing derusting device through a flange; the splashing derusting device is internally provided with a grid plate, a cloth bag dedusting device and a purifier from bottom to top; the top of the splashing derusting device is provided with an exhaust port and a pollutant detection device; a slag discharge pipe at the bottom of the splashing derusting device is connected with the isolation tank through a relief valve; the control device is connected with all single-channel switches. The device has a paint droplet, dust and VOC synchronous treatment function, can automatically monitor and regulate the treatment effect and pressure, and has the VOC treatment rate exceeding 99.5%; and the device has the advantages of simple structure and low manufacturing processing cost.

Description

technical field [0001] The invention relates to an environment-friendly splash derusting device. 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 enlarged 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...

[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 enlarged 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. It includes 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 outlet of the settlement pit, and a labyrinth paint baffle plate , the labyrinth paint baffle is arranged below the grid plate, a labyrinth paint baffle and an organic gas adsorption device are added, the treatment effect of the overall oversprayed paint particles is improved, and the emission of organic gases is reduced. The device realizes the simultaneous treatment of paint mist and VOC; the disadvantages of the device are: the complex structure of the equipment, large footprint and space, high cost of manufacturing, maintenance and management of the equipment, and when the processing device is not normal, it cannot automatically monitor and control.
