Abstract

The invention relates to the technical field of industrial flue gas filtering materials and particularly relates to a double-layer filter material and a filter bag. The double-layer filter material comprises an upper filter layer and a lower filter layer. The upper and lower filter layers are connected through a joint point. A high-temperature coating film layer is arranged on one side of the upper filter layer far away from the lower filter layer. The high-temperature coating film layer is connected to the upper filter layer through the coating layer. A filter bag is prepared from any one ofthe double-layer filter materials. The filter material is divided into an upper filter layer and a lower filter layer. According to different effects of the upper and lower layers, the filter materials are rationally selected so that the strength is increased and the use requirements under the working conditions are satisfied. The high-temperature coating film layer, the coating layer, the upper filter layer and the lower filter layer form four-stage high-efficiency filtration and satisfy the ultra-low emission requirements of dust. The double-layer filter material has a high filtration precision, high tensile strength and a long service life and is easy to promote and use.

Description

technical field [0001] The invention relates to the technical field of industrial flue gas filter materials, in particular to a double-layer filter material and a filter bag. Background technique [0002] At present, the bag filter is a device that uses a bag-shaped filter element made of fabric to capture solid particles in a dust-laden gas. It is a dry dust filter device and is suitable for capturing fine, dry, non-fibrous dust. The emergence of new filter materials and various forms of automatic dust removal methods has made this dust removal equipment with a history of more than 100 years perfect day by day, and is widely used in modern industrial dust removal. [0003] The filter material of the bag filter in the prior art has poor strength, poor filtering effect and serious chemical corrosion, which seriously affects the dust removal effect of the filter. Contents of the invention [0004] The object of the present invention is to provide a double-layer filter mater...
