It is contemplated that the material of construction is not limited to corrugated cardboard, but may be any other structural form of cardboard or any other material sheet material having suitable physical and chemical properties, and that the manufacturing process is not limited to stamping, but may be any other possible forming process such as cutting, jigsaw, etc.
And according to the specific working condition characteristics, other auxiliary filter medium layers such as honeycomb paper, paint mist cotton, non-woven fabrics and the like can be matched and arranged at the air outlet of the dry paint spray booth, so that a certain composite type multilayer stamping corrugated board paint mist filter is formed, or the dry paint mist filter is combined and connected in series with a paint mist filter manufactured by other filter media to be used, so that various high-efficiency and durable composite type paint mist filters are formed, the high-efficiency capturing capability of the paint mist filter on large-scale to medium-small-scale undried paint mist particles (liquid drops) is fully exerted, the high-efficiency capturing capability of other types of filter media on small-scale undried paint mist is effectively exerted, the advantage complementation is realized, the comprehensive durability and the effective service life of the dry paint spray booth paint mist filter system are greatly and synchronously improved, the filtering precision is improved, and the consumption cost of the filter media is greatly saved, and greatly reduces the labor consumption for maintenance.
Example 2

Example 3
The partial baffle plates 124 in the multi-layer baffle plates 124 of the paint mist filter in the embodiment 1 are changed into the baffle plates 124 with larger area of the air passing channel 125 to form the paint mist filter with low wind resistance and full height, and the actual baffling effect of each layer of the baffle plates 124 is ensured to the maximum extent under the condition of obviously reducing the wind resistance, so that the paint mist filtering efficiency as high as possible is obtained.
Example 4
The paint mist filter is only provided with the 1 st to 9 th layers of baffle plates 124 in the embodiment 3, the lengths of the corner insert plate 121, the side insert plate 122, the wind pressure resistant insert plate 123 and the corrugated case body 11 of the corresponding paint mist filter are all shortened, the length and the volume of the whole paint mist filter are reduced, and the low wind resistance half-high paint mist filter is formed.
It is conceivable to add other filter media layers (such as honeycomb paper, paint mist cotton, non-woven fabric, etc.) capable of more efficiently filtering micro-scale paint mist at the air outlet of the paint mist filters in the embodiments 1 to 4, thereby forming a composite type multi-layer punched corrugated cardboard paint mist filter, so as to ensure higher saturation resistance durability and longer service life, and simultaneously, significantly improve the filtering efficiency of the micro-scale paint mist.
Or at one end of the air outlet of the paint mist filter in the embodiments 1 to 5, other types of paint mist filter standard modules (such as a honeycomb paper paint mist filter module, a paint mist cotton paint mist filter module, a DPA paint mist filter module, and the like) capable of more efficiently filtering the tiny paint mist are jointly installed in series, so that a composite type dry paint spray booth never-dried paint mist filter system is formed, and the advantages of the modules are mutually complemented, so that the whole system not only has higher saturation resistance durability and longer service life, but also the filtering efficiency of the system on the tiny paint mist is remarkably improved, the ventilation energy consumption of the system is remarkably reduced, and the environment-friendly quality of air emission is achieved.
The paint mist filter of the multilayer stamping corrugated board is particularly good at long-time trapping and removing a large amount of large-scale to medium-small-scale undried paint mist contained in an exhaust system of a dry paint spray booth, so that if the paint mist filter is used together with other filters (such as DPA paint mist cotton filters and the like) which are better at filtering the small-scale undried paint mist, the paint mist filter can be used as a primary filter of the latter, the effective service life of the latter can be prolonged exponentially, a finer integral paint mist filtering effect can be achieved, the consumption cost and the maintenance labor of filter materials are greatly reduced, and the shutdown maintenance time and the frequency of a factory production line are reduced. And because the wind resistance is greatly reduced, the energy consumption of the ventilation system of the dry paint spray booth is also obviously saved.
