High-strength heat-resistant particulate matter collection filter membrane

The utility model relates to the technical field of filter membranes, in particular to a high-strength heat-resistant particulate matter collecting filter membrane which comprises a frame, a coarse filtering membrane layer, a first fine filtering membrane layer, a waterproof filtering membrane layer, a first heat-resisting net layer, a second fine filtering membrane layer, a second supporting net layer, a third fine filtering membrane layer, a first supporting net layer, a second heat-resisting net layer and a fourth fine filtering membrane layer are sequentially arranged on the inner wall of the frame from top to bottom, and first slopes are arranged on the outer walls of the two sides of the top end of the coarse filtering membrane layer. Filter membrane hair is arranged on the outer wall of the top end of the inclined plane I; the fine filter membrane layer II and the fine filter membrane layer III are arranged in a V shape; the filtering effect is guaranteed, particulate matter collection is facilitated,
