Abstract
The utility model belongs to a combustion apparatus, and particularly relates to a tangential air supply combustion apparatus with an annular air bellow. The tangential air supply combustion apparatus with the annular air bellow is used for solving the problems that when a conventional air supply combustion apparatus is used, as the mixing of airflow and fuels is insufficient and the local air supply quantity is insufficient during combustion, the combustion is insufficient, and the combustion efficiency is directly affected. The tangential air supply combustion apparatus with the annular air bellow comprises the annular air bellow (1), multiple upper air supply pipes (2) and multiple low air supply pipes (3), wherein a barrel (4) is arranged in the annular air bellow (1), the multiple upper air supply pipes (2) are uniformly arranged on the upper surface of the annular air bellow (1) along the periphery of the annular air bellow (1), and the multiple low air supply pipes (3) are uniformly arranged on the inner side wall of the annular air bellow (1) along the periphery of the annular air bellow (1). The tangential air supply combustion apparatus with the annular air bellow is used for the air supply of a boiler combustion device.
Description
Technical field
A burner, the utility model is specifically related to a kind of boiler annular bellows circle of contact air-supply burner.
Background technology
Existing boiler and burner annular bellows air-supply arrangement is generally divided into upper and lower two-stage air-supply, and higher level's air-supply is blown into after cylindrical shell and fuel mix, and the burning torch of all directions is lighted a fire together, and fuel is lighted from all directions, guarantee its burning steadily.For air-supply, wind speed is larger, more abundant burn also just more complete of mixing.Subordinate's air-supply is responsible for supplementing air quantity, fresh air is endlessly added in cylindrical shell, thereby avoided the insufficient situation that affects the thermal efficiency of fuel combustion causing owing to lacking air, at present on annular bellows, lower ajutage and cylindrical shell are arranged vertically, blow everywhere and be vertically blown into cylindrical shell along airduct, this arrangement is perfect not, its reason is: in cylindrical shell axle center, locate, the air-flow that all directions are blown into meets and clashes into mutually, energy is cut down mutually, wind speed has also just reduced many, although the air-flow of cylindrical shell center is better owing to clashing into the disturbance producing, but near barrel, even the flow perturbation in centre position is all more weak, see on the whole, air-flow is abundant not with mixing of fuel, local air supply quantity not sufficient during burning, thereby cause burning abundant not, directly affect efficiency of combustion.
Utility model content
The utility model is abundant not with mixing of fuel for solving existing air-supply burner air-flow, local air supply quantity not sufficient during burning, thereby cause burning abundant not, directly affect the problem of efficiency of combustion, and then propose a kind of annular bellows circle of contact air-supply burner.
The utility model takes technical scheme to be for addressing the above problem: the utility model comprises cylindrical shell 4, described a kind of annular bellows circle of contact air-supply burner also comprises annular bellows 1, a plurality of upper ajutage 2 and a plurality of lower ajutage 3, cylindrical shell 4 is arranged on the inside of annular bellows 1, a plurality of upper ajutages 2 are arranged on the upper surface of annular bellows 1 along the circumference uniform distribution of annular bellows 1, and a plurality of lower ajutages 3 are arranged on the madial wall of annular bellows 1 along the circumference uniform distribution of annular bellows 1.
The beneficial effects of the utility model are: before using the utility model, place, cylindrical shell axle center, the air-flow that all directions are blown into meet clash into mutually, energy cuts down mutually, wind speed is lower, near barrel, even the flow perturbation in centre position is more weak.The utility model can avoid causing because of airflow collision the generation of energy attenuating, and air velocity is higher, can make fuel and air well mix, thereby make fuel combustion more abundant, and efficiency of combustion has improved 40%.
Accompanying drawing explanation
Fig. 1 is the integrally-built schematic diagram of the utility model; Fig. 2 is that the A-A of Fig. 1 is to view; Fig. 3 is that the B-B of Fig. 1 is to view.
The specific embodiment
The specific embodiment one: as Figure 1-3, a kind of annular bellows circle of contact air-supply burner of present embodiment, it comprises cylindrical shell 4, described a kind of annular bellows circle of contact air-supply burner also comprises annular bellows 1, a plurality of upper ajutage 2 and a plurality of lower ajutage 3, cylindrical shell 4 is arranged on the inside of annular bellows 1, a plurality of upper ajutages 2 are arranged on the upper surface of annular bellows 1 along the circumference uniform distribution of annular bellows 1, and a plurality of lower ajutages 3 are arranged on the madial wall of annular bellows 1 along the circumference uniform distribution of annular bellows 1.
The specific embodiment two: as Figure 1-3, described in present embodiment, ajutage 2 comprises blast pipe 2-1 and discharge pipe 2-2 on each, blast pipe 2-1 and discharge pipe 2-2 make one, the axis of blast pipe 2-1 is perpendicular to the upper surface of annular bellows 1, the angle α that the circle diameter of the axis of discharge pipe 2-2 and annular bellows 1 forms is 5 °~15 °, and the angle β that each lower axis of ajutage 3 and the circle diameter of annular bellows 1 form is 7 °~20 °.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: as Figure 1-3, described in present embodiment, the internal diameter of cylindrical shell 4 is 3640mm, the tangential circle diameter D that on a plurality of upper ajutages 2, the axis of discharge pipe 2-2 forms is 800mm, and the tangential circle diameter d that the axis of a plurality of lower ajutages 3 forms is 900mm.Other composition and annexation are identical with the specific embodiment one or two.
Operation principle
The utility model is adjusted ajutage angle, the oblique cylindrical shell that is blown into makes to blow, this arrangement can make to blow everywhere and take cylindrical shell axle center as a circle of contact of center of circle formation, the circle of contact can well disturbance air, generation is similar to the effect of cyclone, its cardinal principle is that the air-flow of all directions all flows along clockwise direction, frictional force is mutually little, speed can maintain under higher state, can not produce the situation that weakens energy because of collision, simultaneously because air velocity is higher, can drive fuel to do together High Rotation Speed, fuel and air can well mix, make fuel combustion abundant, simultaneously by upper, different angles is adjusted in lower air-supply, can make two-stage air-supply upper, in lower two aspects, form two circle of contacts that vary in size, because flow velocity between two-layer air-flow is different, can produce phase mutual interference, thereby make the more abundant of fuel combustion, improve efficiency of combustion.
