Abstract
The utility model discloses a single-cylinder longitudinal smokeless boiler, comprising a boiler body whose bottom is provided with a chain grate; a boiler cylinder is provided at the top of the burning chamber of the boiler body; a boiler arch connected with the front arch of the boiler body in a sealing way is provided in the burning chamber; an air pipe supplied air by a blowing machine is provided in the arch top of the boiler arch open end positioned at the middle of the burning chamber; nozzles for blowing air to burning chamber are uniformly distributed on the lower surface of the air pipe; smoke baffle walls are respectively provided at both sides of the boiler arch; smoke inlets are respectively formed between the front side ends of the two smoke baffle walls and the front arch of the boiler body; a smoke channel is formed between the smoke baffle walls and the corresponding boiler body side walls. The utility model without a dust removing device has small smoke exhaust resistance, implements smokeless exhaust, and reduces largely boiler operation cost, invention cost and maintenance cost.
Description
Technical field
The utility model belongs to the improvement of single drum longitudinal boiler structure, particularly single drum longitudinal less boiler.
Background technology
The flue gas flow of existing single drum longitudinal boiler all is more than three backhauls, and the fume emission resistance is big, need be used the bigger air-introduced machine of power when work the flue gas in the combustion chamber is outwards taken out, so that make the flue gas recirculation smoothness, is beneficial to the burning of coal.Though can increase the flow velocity of flue gas in the body of heater like this, the fine dusts in the combustion chamber of furnace body and do not have the black wood charcoal grain of completing combustion also to be extracted into body of heater to enter in the air, cause atmosphere pollution outward thereupon.For dedusting, need huge deduster be set at boiler tail, and this has increased the resistance of flow of flue gas in the body of heater.The method of servicing units such as air-introduced machine, deduster is installed in this employing additional, not only can not effectively address the above problem, but also has increased operating cost, cost of investment and the maintenance cost of boiler greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of single drum longitudinal less boiler, not only the fume emission resistance is little, and need not to join in addition servicing units such as deduster, air-introduced machine and just can realize smokeless emission, can greatly reduce operating cost, cost of investment and the maintenance cost of boiler.
The purpose of this utility model is achieved in that a kind of single drum longitudinal less boiler, chain fire-gate body of heater is housed bottom comprising, the top of combustion chamber of furnace body is being provided with drum, the chimney arch that links to each other with the sealing of body of heater face arch is being set in the combustion chamber, the vault that is positioned at the chimney arch open end at middle part, combustion chamber is being provided with the airduct of being blown by air blast, uniform tuyere of in the combustion chamber, drying on the lower surface of airduct, the chimney arch both sides are being provided with brick baffle respectively, form respectively between the front side end of two brick baffles and the body of heater face arch and advance mouth, form flue between brick baffle and the relative sidewall of the furnace body, the rear end of both sides flue is being communicated with back smoke box.
During the utility model work, coal is sent into the combustion chamber internal combustion by traveling-grate stoker, because the airduct by the air blast air-supply is being set in the vault of chimney arch open end, sufficient oxygen can be blowed to by tuyere uniform on the airduct lower surface in the combustion chamber, fine dusts in the combustion chamber and black wood charcoal grain just can fully burn like this, reach the effect of smokeless or low dirt discharging, the gas fume after burning chimney arch top face of upwards turning back, again by advancing in the flue that mouth enters the chimney arch both sides respectively of forming between brick baffle front side end and the body of heater face arch, through after smoke box discharge.Flue gas flow of the present utility model has only two backhauls, thereby the fume emission resistance is little, coal burning in the combustion chamber of furnace body is abundant in addition, it is minimum that the dust in flue gas equal size is dropped to, therefore do not need to install auxiliary equipment such as deduster and air-introduced machine, therefore can greatly reduce operating cost, cost of investment and the maintenance cost of boiler.

The specific embodiment
A kind of single drum longitudinal less boiler as shown in Figure 1, is equipped with the body of heater of traveling-grate stoker 1 bottom comprising, the top of combustion chamber of furnace body is being provided with drum 4, and the axis of the axis direction of drum 4 and traveling-grate stoker 1 in the same way.The chimney arch 7 that links to each other with 13 sealings of body of heater face arch is being set in the combustion chamber, as shown in Figure 1 and Figure 2, the vault that is positioned at chimney arch 7 open ends at middle part, combustion chamber is being provided with the airduct 8 of being blown by air blast, uniform tuyere of in the combustion chamber, drying on the lower surface of airduct 8, sufficient oxygen can be blowed in the combustion chamber by uniform tuyere on airduct 8 lower surfaces, fine dusts in the combustion chamber and black wood charcoal grain just can fully burn like this, can greatly reduce the discharging of fine dusts and black wood charcoal grain.As shown in Figure 2, the both sides of chimney arch 7 are being provided with respectively to form respectively between the front side end of brick baffle 12, two brick baffles 12 and the body of heater face arch 13 advances mouth 5, forms flue between brick baffle 12 and the relative sidewall of the furnace body, and the rear end of both sides flue is being communicated with back smoke box 9.Water screen tube 6 uniformly at intervals vertically is being set respectively in the inside and outside both sides of brick baffle 12 and both sides flue, is helping absorbing heat energy contained in the flue gas like this, improving the heat energy utilization rate.As shown in Figure 3, the upper end bending of water screen tube 6 is communicated with drum 4, and its lower end is being communicated with the vertical water inlet pipe 11 that is positioned at the flue bottom.Flue gas behind coal burning chimney arch 7 top face of upwards turning back, again by advancing in the flue that mouth 5 enters chimney arch 7 both sides respectively of forming between brick baffle 12 front side end and the body of heater face arch 13, pass between the water screen tube 6 of flue gas in the flue, wash away depositing dust once more,, strengthens the effect that smokeless or low dirt discharges after back smoke box 9 is discharged.
As shown in Figure 1 and Figure 2, in body of heater face arch 13, be the lateral separation uniform be provided with before arch tube 3, the upper end of preceding arch tube 3 is communicated with drum 4 respectively, its lower end respectively be arranged on body of heater face arch 13 bottoms in preceding horizontal water pipe 16 be communicated with.The front that is positioned at the body of heater rear arch of combustion chamber is the uniform rear arched tube 14 that is being provided with in lateral separation, and the upper end of rear arched tube 14 is communicated with drum 4, and its lower end is being communicated with the back horizontal water pipe 15 that is positioned at rear end, bottom, combustion chamber.
