Abstract
The utility model provides a DZL water tube and fire tube packaged boiler which has reliable support and tight sealing, comprises a chain grate on the lower part, wherein water cooling walls on both sides are arranged on the upper part of the chain grate, a boiler barrel, water cooling walls on both sides and a cover plate make up a convection smoke channel, the water cooling walls on both sides adopt membrane-wall structure of flat steels welded between arch tubes; a front arch and a rear arch respectively adopt an front arch tube and lower convection tube which are intersected to form the water tube of rear arch tube as support framework so as to form water cooling arch structure. As membrane water cooling structure is adopted, the optimum heat transfer and heat insulation seal structure is realized. The front arch and rear arch respectively adopt the water tubes of the front arch tube and the rear arch tube as support frameworks so that the work condition of fireproof material of the front arch and rear arch are improved; the arch collapse situation caused by fracture of fireproof material is prevented.
Description
Technical field
The utility model belongs to a kind of small-sized industrial boiler, relates in particular to be used for by a kind of boiler plant of steam is provided behind coal combustion and the class ature of coal fuel.
Background technology
DZL feeded water rapidly multitubular boiler is that the industry of single drum longitudinal chain grate boiler is called for short.DZL feeded water rapidly multitubular boiler is a kind of common small-sized industrial boiler, especially provides in the steam link behind coal combustion and the class ature of coal fuel in industry and life and generally uses.At present the state of the art of DZL feeded water rapidly multitubular boiler is that two side walls adopt common light pipe, exist poorly sealed close, the shortcoming that the fire-proof heat-insulating function is relatively poor.Face arch, rear arch adopt heat-insulating material to make, and lack secure support, and operating temperature is more than＞1000 ℃, and service life is short, and poor reliability is collapsed in fracture easily.
The utility model content
The purpose of this utility model provides a kind of DZL feeded water rapidly multitubular boiler reliable, that sealing is tight that supports.
In order to achieve the above object by the following technical solutions: the traveling-grate stoker that comprises the bottom, be positioned at anterior coal bunker, be arranged on face arch and rear arch in the boiler, upper boiler is provided with drum, drum connects convection tube down, and drum inside is provided with the pyrotechnics pipe, and traveling-grate stoker top is provided with two side walls, drum, two side walls, cover plate surround convection pass, and two side walls adopt the membrane wall structure of Welding flat steel between light pipe; The convection tube pipe at middle part is the cover plate made by heat-insulating material of offset supports to the inside, and the water pipe that the convection tube of arch tube and bottom intersected to form rear arched tube before face arch, rear arch adopted respectively forms the water-cooled arch structure as support frame.
Adopt above technical scheme, adopt film water cold wall structure, realized best heat transfer and adiabatic hermetically-sealed construction.Face arch, rear arch adopt the water pipe of preceding arch tube, rear arched tube as support frame respectively, have improved face arch, rear arch refractory material condition of work, have eliminated the arch that produces because of the refractory material fracture phenomenon of collapsing.

The specific embodiment
Embodiment
A kind of DZL feeded water rapidly multitubular boiler, the traveling-grate stoker 1 that comprises the bottom, be positioned at anterior coal bunker 2, be arranged on face arch 4 and rear arch 6 in the boiler, upper boiler is provided with drum 7, and drum connects convection tube 8 down, drum inside is provided with pyrotechnics pipe 9, traveling-grate stoker top is provided with two side walls 10, and drum 7, two side walls 10, cover plate 11 surround the membrane wall structure that convection pass 12, two side walls 10 adopt Welding flat steel between light pipe; Convection tube 8 pipes at middle part are the cover plate 11 made by heat-insulating material of offset supports to the inside, and face arch 4, rear arch 6 adopt the convection tube of preceding arch tube 3, bottom to intersect to form the water pipe of rear arched tube 5 as support frame respectively.Convection tube 8 and rear arched tube 5 are that same pipe constitutes.
Coal and class ature of coal fuel drop on the traveling-grate stoker through coal bunker and burn, under the effect of face arch, rear arch, fully gas fume after burning is successively by convection pass be positioned at the pyrotechnics pipe of drum inside and water or other heat transfer medium of the heat transferred inside of burning produced the steam heat medium that needs for the user.It is heat transfer and the exterior wall that constitutes fire-proof heat-insulating that two side walls mainly act on.Face arch, the main effect of rear arch are to promote burning, improve the efficient and the fuel scope of application of burning.
