Abstract
The utility model relates to the field of hot blast stoves, in particular to a dual-lambdoidal furnace arch device of a hot blast stove, which is characterized in that a lambdoidal front arch is arranged on the front end above the hot blast stove, a lambdoidal rear arch is arranged on the rear end above the hot blast stove, the front end of the hot blast stove is connected with a coal charging hopper, and a chain grate stoker is arranged on the hot blast stove. Outlet ends of the lambdoidal front arch and the lambdoidal rear arch are lambdoidal. Due to the adoption of the technical scheme, the front arch and the rear arch which have a dual-lambdoidal furnace arch combination are beneficial to enlarging of the application range of coal types; and the dual-lambdoidal furnace arch device has the advantages of being simple in structure, increasing heat utilization rate and lowering production cost.
Description
Technical field
The utility model relates to the hot-blast stove field, is that a kind of hot-blast stove has two lambdoid furnace arch devices.
Background technology
Former chain-arranged type hot-blast stove has thermal efficiency shakiness, on the low side; Difficulty all occurs in the fire of ining succession that has, and more can say that with efficient energy waste is quite serious without exerting oneself.Affect the cigarette temperature that key that fresh fuel catches fire is front arch area, and the height of cigarette temperature depends primarily on the rear arch outlet, the high-temperature flue gas flow depth enters the degree of face arch and the time of staying there.
Summary of the invention
The purpose of this utility model is to provide a kind of chain-arranged type hot-blast stove to have two lambdoid furnace arch devices, sufficient combustion, energy savings.
The utility model is achieved in that by hot-blast stove, traveling-grate stoker and upper coal bunker and forms; It is characterized in that front end is equipped with the herringbone face arch above hot-blast stove, the herringbone rear arch is equipped with in the rear end above hot-blast stove; Front end at hot-blast stove is connected with upper coal bunker, and traveling-grate stoker is arranged on hot-blast stove.
The port of export of herringbone face arch and herringbone rear arch is herringbone.
Owing to adopted technique scheme, have the front and back arch of Energy saving hearth combination, be conducive to enlarge the accommodation of coal; Simple in structure, improved heat utilization efficiency, reduced again production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, herringbone face arch; 2, herringbone rear arch; 3, hot-blast stove; 4, traveling-grate stoker; 5, upper coal bunker.
The specific embodiment
The utility model is further described below in conjunction with drawings and Examples.
In Fig. 1, front end is equipped with herringbone face arch 1 above hot-blast stove 3, and herringbone rear arch 2 is equipped with in the rear end above hot-blast stove 3; Front end at hot-blast stove 3 is connected with upper coal bunker 5, and traveling-grate stoker 4 is arranged on hot-blast stove 3.
During the hot-blast stove operation, fresh fuel is fallen on traveling-grate stoker 4 fuel beds by upper coal bunker 5, along with moving into of traveling-grate stoker 4 finished preheating in the stove.Dry before this at warm-up phase, then decompose volatile matter.Preheating is later on ignition and after-flame stage.The origin of heat that the fuel preheating stage absorbs is in two aspects: the heat radiation in the burner hearth, the heat conduction of the coal that is burning.What play a major role is the heat radiation of chimney arch.Raising first so the temperature of fuel bed is the superiors, also is dry at first.The lower-layer fuel temperature rises slowly, just can obtain drying after traveling-grate stoker 4 is walked out a segment distance, and is dry complete, begins distillation again.The thermal decomposition process of coal is distillation on the one hand, and having an effect with the air of coming in from air compartment again on the other hand generates CO, and these two kinds of gases are mixed into fuel gas, rise in the combustion chamber and burn.The high-temperature flue gas that burning produces rises to secondary furnace relaying afterflame to the greatest extent from the combustion chamber, flue gas enters cooling chamber by smoke outlet window, and flying dust obtains sedimentation.So that the hot-blast stove soot emissions meet the regulation of GB/T13271 " emission standard of air pollutants for boilers ".
