Bag dedusting coal gas guide-in pipe sealing structure of Ouye furnace

The invention discloses a bag dedusting coal gas guide-in pipe sealing structure of an Ouye furnace. The sealing structure mainly comprises an annular plate (1), a cylindrical pipe (2), an annular plate (3), a cylindrical pipe (4), an annular plate (5), an cylindrical pipe (6), an annular plate (7), an cylindrical pipe (8), a pattern partition board (9), a padding and gland seal (10), a crude gasguide-in pipe (11) and reinforcing rib plates (12). The cylindrical pipe (2) is cylindrical. The upper portion of the cylindrical pipe (2) is assembled and welded to the annular plate (1). The annularplate (3) is manufactured in sequence. The inner diameter of the annular plate (3) is 80 mm greater than the outer diameter of a crude gas pipe. The outer circumference of the annular plate (3) is welded and connected to the lower portion of the cylindrical pipe (2). The inner circumference of the annular plate (3) is welded and connected to the upper portion of the cylindrical pipe (2). The annular plate (3), the cylindr
