Metal filter

The present invention relates to a metal filter, and more particularly, to a method for manufacturing a metal filter for purifying contaminated air that can be exhausted in various industrial fields, which can reduce the weight and improve the coupling performance between the filtering members. The present invention relates to a metal filter of a new coupling structure.

Air that can be exhausted from various industries, such as nuclear power plants, polymers, chemicals, coating lines, chemicals, hydraulics, and measuring equipment, includes pollutants such as chemicals, oils, and foreign substances. Since it is a factor of pollution, air must be purified and exhausted, and filters of various kinds and materials are used to purify the exhausted air.

The above filter can be largely classified into a synthetic resin filter and a metal filter. However, it is inconvenient to use the filters of synthetic resin because it is common to replace the filter with a new one every time after using it for one-time use, and it can be a factor of environmental pollution because the replaced filter is difficult to reuse. In some cases, the synthetic resin filter is washed and reused, but it is not efficient because only a few times it needs to be reused.

In addition, since the temperature range that can be used is limited to 80 ℃ to 250 ℃ and thermal and chemical durability is weak, a pretreatment facility such as a cooling system to prevent high temperature operation is required, and accordingly design, construction, maintenance, operating costs There is an increasing problem.

Therefore, there is a need for a material of a new filter bag that is resistant to high temperature and high pressure, and has high thermal and chemical durability. Accordingly, the use and demand of metal filters are increasing.
