Abstract
The utility model relates to a novel oxygen supply device for a coal-fired device. According to the oxygen supply device, oxygen supply in a hearth can be effectively balanced to guarantee more uniform oxygen supply, so that coal can be more fully combusted, and meanwhile, the effect of controlling temperature in the hearth can be realized well by adjusting rotation speed of a fire bar. The oxygen supply device comprises a fire bar which is arranged in the hearth, wherein air boxes are arranged on the two sides of the fire bar and are connected with a blower on the fire bar; an air chamber is arranged between bellow passages of the air boxes; a plurality of air scoops are arranged in the air chamber and are communicated through air ducts; one end of each of the air boxes is connected with the blower, and the other end of each of the air boxes is connected with the air duct on the middle part of the fire bar; the number of the air scoops is two or more; closed spaces are formed on the bottom surface and the four sides of the air scoops, and the upper ends of the air scoops are open and face the fire bar; a side face opening of each air scoop is communicated with the air duct; the blower is arranged at the front end or the rear end of the fire bar; an air inducing mechanism is arranged in the hearth; and an adjusting valve is arranged on the air duct.
Description
One, technical field:
The utility model relates to a kind of coal-burning device, especially relates to a kind of novel coal device oxygen supply device, and it is a kind of boiler grate oxygen supply device.
Two, background technology:
In the background technology, the oxygen supply equipment of existing fire grate has only air compartment, does not have wind scoop; The wind (oxygen) that is blown in the air blast directly gets into air compartment through bellows, cause air compartment middle part air quantity a lot, and the air quantity of both sides is less; Thereby the air capacity (oxygen) that causes rising to fire grate is inhomogeneous, make that the middle part burning is too fast prosperous excessively, and the edge burning is insufficient; The rotating speed adjustment of fire grate can not address this problem; Not only caused the waste of coal resources, imperfect combustion also can produce more waste gas, contaminated environment simultaneously.
Three, utility model content:
The utility model is in order to solve the weak point in the above-mentioned background technology; A kind of novel coal device oxygen supply device is provided; Its ability active balance burner hearth oxygen supply; Make oxygen supply average, thereby coal can be burnt more fully, also can realize well simultaneously reaching action of temperature in the control burner hearth through the rotating speed of adjustment fire grate.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of novel coal device oxygen supply device comprises the fire grate that is arranged under the burner hearth, and it is characterized in that: the fire grate both sides are provided with bellows; Bellows are connected with air blast on being arranged on fire grate; Between the bellows road of bellows is air compartment, is provided with a plurality of wind scoops in the air compartment, is communicated with through airduct between the wind scoop.
Above-mentioned bellows one end is connected with air blast, and an other end links to each other with the airduct that is arranged on the fire grate middle part.
Above-mentioned wind scoop is two or more, the bottom surface of wind scoop with form enclosure space all around, open upper end is towards fire grate.
A lateral opening of above-mentioned wind scoop is communicated with airduct.
Above-mentioned air blast is arranged on fire grate front end or rear end.
Be provided with air inducing mechanism in the above-mentioned burner hearth.
Above-mentioned airduct is provided with control valve.
Compared with prior art, the advantage and the effect that the utlity model has are following:
1, the utility model can effectively improve the thermal efficiency and coal burning efficient, and energy savings reduces pollutant emission.
2, the utility model is divided into two or more wind scoops with air compartment.The air that air blast blasts is introduced into each wind scoop, makes progress through wind scoop after the combustion again, and the air quantity in each wind scoop is tending towards average.
3, the even air in the utility model wind scoop upwards arrives the coal seam through the fire grate gap, makes the coal that is tiled on the fire grate can evenly receive oxygen, fully burning.
4, evenly receive oxygen to make the middle part of fire grate and the coal on both sides can fully receive oxygen, fully burning keeps same combustion efficiency, and burner hearth middle part and sidepiece temperature are reached unanimity, and can regulate furnace temperature through the rotating speed of adjusting road fire grate and the blow rate required of air blast.
Four, description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure, the 1-coal bunker; The 2-air compartment; 3-air compartment air door; The 4-air blast; The 5-control valve; The 6-fire grate; The 7-wind scoop; The 8-airduct; The 9-bellows; The 10-burner hearth.
Five, the specific embodiment:
The utility model burner oxygen supply equipment mainly comprises fire grate front end coal bunker, is arranged at the air compartment in the middle of the fire grate, the two or more wind scoops in the air compartment, and bellows are arranged at air blast and other attaching parts of fire grate front end or rear end.Referring to Fig. 1 and Fig. 2, comprise the fire grate 6 that is arranged under the burner hearth 10, fire grate 6 both sides are provided with bellows 9; Bellows 9 one ends are connected with air blast 4, and an other end links to each other with the airduct 8 that is arranged on fire grate 6 middle parts, and air blast 4 is arranged on fire grate 6 front ends or rear end; Be air compartment 2 between the bellows road of bellows 9, air compartment 2 has air compartment air door 3, and wind scoop 7 is set in the air compartment 2; Wind scoop 7 is two or more, the bottom surface of wind scoop 7 with form enclosure space all around, open upper end is towards fire grate 6; A lateral opening of wind scoop 7 is communicated with airduct 8, and airduct 8 is provided with control valve 5, also can be provided with air inducing mechanism in the burner hearth 10.
During real work; Fire grate 6 at the uniform velocity moves from coal bunker 1 (front end) to the back-end, and the air blast 4 that is arranged at fire grate 1 front end or rear end blasts fresh air (oxygen) in the bellows 9, and air with pressure arrives air compartment 2 through bellows 9; Through being arranged at airduct 8 entering in the air compartment 2 and being full of each wind scoop 7; Wind scoop 7 bottoms and be enclosure space all around, air can be from wind scoop 7 open upper end, and the slit through fire grate 6 arrives the coal seam and gets into burner hearth 10 burnings.
The utility model can but be not limited in burner hearth, be equipped with blower unit, be equipped with blower unit, can accelerate air at bellows, the flowing velocity in the airduct, wind scoop, accelerated combustion promotes fire box temperature rapidly.The utility model is oxygen supply effectively on average, makes middle part, coal seam and edge can both receive oxygen even, flameholding, thorough.Energy savings reduces the dusty gas discharging.
