A multi-stage paint mist trapping device and method for trapping and separating overspray

Abstract

The invention provides a multistage paint mist trapping device and a dry paint spraying system applying the same. The paint mist trapping device is characterized in that at least two types of paint mist trapping units are arranged in the paint mist trapping device and are vertical to the air main flow direction; each paint mist trapping unit is in a full slice structure and covers the flow area of air; the external dimensions of different types of paint mist trapping units are the same; standard clamp slots are formed in the paint mist trapping device; any one type of paint mist trapping unit can be arranged in any one standard clamp slot. The multistage paint mist trapping device has the advantages that through the standardized design, the types of the paint mist trapping units in the paint mist trapping device can be adjusted according to the difference of the particle characteristics of overspray matters, so that each paint mist trapping unit in the paint mist trapping device bears load and three-dimensional paint mist trapping and accommodation space is formed in the inner space of the whole paint mist trapping device, thus greatly improving the paint mist trapping and accommodation capacities and separating effects of the paint mist trapping device.

Description

technical field [0001] The invention relates to the field of industrial coating, in particular to the field of trapping, separating and collecting sprayed overspray, in particular to a multi-stage paint mist trapping device, which is widely used in the painting of automobiles, hardware, home appliances, toys and the like. Background technique [0002] With the rapid development of China's economy, environmental pollution has become more and more serious. In most parts of our country, human pollution of air, soil and water has far exceeded the capacity of nature. In recent years, smog has occurred frequently, and water pollution and soil pollution have become more and more serious. Painting is a highly polluting and energy-intensive industry. During the coating production process, a large amount of exhaust gas, waste liquid and solid waste will be generated. In order to maintain the constant temperature and humidity conditions required for painting, a large amount of elect...

Problems solved by technology

Compared with the traditional paint mist adsorption felt, the paint mist trapping device of this layout has greatly improved the paint mist trapping capacity, but the paint mist trapping device of this structure contains many paint mist The mist collection unit, the manufacture of the paint mist collection unit is very difficult, the assembly of the paint mist collection device takes a long time, and the paint mist collection device with this structure only intercepts and adheres to the windward side of the paint mist collection unit. Almost no overspray is adhered and captured on both sides and the leeward side of the paint mist collection unit. When the paint mist collection unit reaches the limit of capture and absorption, there is still a large amount of space between the paint mist collection units. Be exploited

The existence of large air flow channels between the paint mist collection units also makes it difficult for this type of paint mist collection box to capture those small and light overspray particles
