The utility model relates to a sealed dry quenching waste-heat recovery boiler with membrane type wall, which comprises an upright column (13), a cross beam (1), a hanger rod (2), a boiler with membrane type wall (4), a ceiling tube (5), a condenser pipe (6), an overheater (7), an evaporator (8), a coal economizer (10) and a boiler outlet (12). The boiler with the membrane type wall (4) is suspended on the cross beam (1) by the hanger rod (2), and the condenser pipe (6), the overheater (7) and the evaporator (8) are up-down sequentially disposed in the boiler with membrane type wall, further the boiler with membrane type wall is formed by a front membrane type wall, a left membrane type wall, a rear membrane type wall and a right membrane type wall. The overheater (7) and the evaporator (8) are suspended by the ceiling tube (5) which is suspended on the cross beam by the hanger rod, and the portion of the overheater (7) and the evaporator (8) which penetrates the membrane type wall is sealed by a corrugated-type expansion joint structure (15), then the upper end of the coal economizer (10) and the lower end of the boiler with membrane type wall (4) are connected with each other through the expansion joint (9) and sealed, further the lower end of the coal economizer (10) and the boiler outlet (12) are connected with each other through the expansion joint (11) and sealed. The sealed dry quenching waste-heat recovery boiler with membrane type wall has the advantages of good sealing and wearing preventive property, good heat expansion property, and stable operation.
