Beschreibung
Zusammenfassung:	The utility model discloses an ultrahigh-temperature basalt composite filter bag which comprises a bag body, an air inlet area is arranged in the middle of the bottom of the bag body, a plurality of groups of air inlet pipes are arranged in the air inlet area, a porous layer is arranged above the air inlet area, a fiber felt layer is arranged above the porous layer, a sponge layer is arranged above the fiber felt layer, and a sealing cover is arranged at the top of the bag body. The sealing cover is of a circular structure, a central opening area is arranged in the middle of the sealing cover, and an annular supporting area is arranged on the edge of the sealing cover. The strength of the bag body is effectively improved, the service life of the bag body is prolonged, the composite fiber layer is formed by compounding basalt fibers, glass fibers and polyacrylonitrile fibers, the base cloth layer is formed by weaving polyurethane fibers and ceramic fibers in a mixed mode, and the five materials have good high-
