Compared with the prior art, the beneficial effects of the utility model are that: the angle tube boiler with the tube frame system has the advantages that the single-drum centralized descending tube form is adopted, the drums are transversely arranged outside a hearth and are not heated, the angle tube boiler has good water storage performance, the full-sealed membrane water-cooled wall structure is adopted, smoke is completely isolated from the outside, the heat insulation performance of a boiler wall is greatly improved, the whole boiler is not provided with an independent boiler supporting steel frame, the boiler is supported by the membrane wall and the descending tube, the equipment cost is reduced, the stability is improved, the repairing difficulty is high after the membrane water-cooled wall is damaged, a plurality of soot blowing points are required to be arranged at specific positions of the hearth and a tail convection heating surface, the regular blowing is realized, the cleaning of the heating surface is ensured, and the safer and more effective operation of the boiler is ensured.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the boiler comprises a boiler barrel, 2, a downcomer, 3, a coiled convection tube bundle, 4, a first membrane wall, 5, a second membrane wall, 6, a header, 7, a first conduit, 8, a second conduit, 9 and a soot blowing point.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: an angle tube boiler with a tube frame system comprises a collecting box 6, wherein first membrane type walls 4 are fixedly connected around the outer wall of the collecting box 6, down pipes 2 are erected at four corners around the collecting box 6, a boiler barrel 1 is erected around the upper portion of the collecting box 6, the boiler barrel 1 is communicated with the down pipes 2, a first guide pipe 7 is erected around the inner portion of the collecting box 6, the angle tube boiler is provided with a pipeline system which is composed of four large-diameter down pipes 2, the first membrane type walls 4, the collecting box 6, a convection heating surface and the like and serves as a framework of the boiler, all boiler loads are borne by the angle tube boiler, a second membrane type wall 5 is fixedly sleeved on the outer wall of the first guide pipe 7, the boiler barrel 1 is communicated with the first guide pipe 7 through a second guide pipe 8, a coiled convection tube bundle 3 is erected on one side of the inner wall of the collecting box 6 through a support, the coiled convection tube bundle 3 is communicated with the first guide pipe 7, a water circulation system of the boiler adopts natural circulation for a hearth part, the convection heating surface of the flue part consisting of the coiled pipe convection tube bundle 3 adopts forced circulation, and the external boiler barrel 1 is adopted, thereby not only ensuring the safety of the boiler during operation, but also ensuring the natural flow of water in the boiler when the boiler is in emergency shutdown, the system backwater enters from the boiler barrel 1, naturally circulates through the first guide pipe 7 and the second guide pipe 8 at the hearth part and then enters the convection heating surface which is arranged in the flue and consists of the coiled pipe convection tube bundle 3, the possibility of low-temperature corrosion of the convection heating surface at the flue gas outlet is effectively reduced, a plurality of ash blowing points 9 are arranged around the coiled pipe convection tube bundle 3, the repair difficulty is higher after the membrane water wall is damaged, therefore, a plurality of ash blowing points 9 are required to be arranged at specific positions of the hearth and the tail convection heating surface for periodic blowing, so that the heating surface is ensured to be clean, and the boiler can run more safely and effectively.
