Abstract

The utility model discloses a novel flow guide plate structure for a burner windbox, which consists of at least two windbox flow guide plates and one circular arc plate (3), wherein the first flow guide plate to the n-th flow guide plate and one circular arc plate (3) are sequentially arranged from the inner side to the outer side of the burner windbox, wherein n is an integer greater than or equal to 2, at an inlet and an outlet of the burner windbox, a ratio of the distance between the inner side wall of the burner windbox and the first flow guide plate/the distance between the first flow guide plate and the second flow guide plate/.../the distance between the (n-1)th flow guide plate and the n-th flow guide plate is 1/1/.../1/1, the flowing work condition of the air in the wind box is sufficiently utilized through the proportion setting between the flow guide plates, the flow guide plate position proportioning mode more suitable for the air flowing is created, the problem of nonuniform air quantity distribution during the 90-degree steering of the air is solved, and in addition, the circular arc plate is additionally arranged at the corner of the outer side wall of the windbox, so the air flowing resistance is reduced, and the air flowing is more stable.

Description

A kind of novel burner bellows deflector structure

Technical field

The utility model relates to a kind of novel burner bellows deflector structure, belongs to the deflector technical field.

Background technology

Two deflector spacer structures that each angle burner of traditional boiler adopts, the port of export deflector unequal approximate 1:1:2 of distance at interval, the shortcoming of this deflector spacer structure is the uniform distribution that can not better guarantee air quantity in the bellows.The Chinese patent 200920073188.7 of the applicant's application, a kind of burner wind-box deflector structure of denomination of invention discloses other part background technologies of the utility model.

The utility model content

The purpose of this utility model provides a kind of uniform distribution that solves the air quantity in the burner wind-box, and better guarantees the burner wind-box deflector structure of secondary air flow and flow velocity.

In order to achieve the above object, the technical solution of the utility model provides a kind of burner wind-box deflector structure, form by at least two bellows deflectors and an arc plate, be followed successively by to the outside from the burner wind-box inboard the 1st deflector, the 2nd deflector ... n-1 deflector, n deflector and arc plate, n is the integer more than or equal to 2, and

In the burner wind-box porch, the distance between described distance, the 1st deflector and the 2nd deflector between burner wind-box madial wall and the 1st deflector ... the distance between n-1 deflector and the n deflector and the ratio of the distance between n deflector and the burner wind-box lateral wall are 1:1: ...: 1:1;

In the burner wind-box exit, the distance between described distance, the 1st deflector and the 2nd deflector between burner wind-box madial wall and the 1st deflector ... the distance between n-arc plate 1 deflector and the n deflector and the ratio of the distance between n deflector and the burner wind-box lateral wall are 1:1: ...: 1:1.

Further, described the 1st deflector, the 2nd deflector ... the two ends of n-1 deflector and n deflector are respectively perpendicular to burner wind-box inlet face and exit face, and the middle part is that circular arc is excessive; Described arc plate 3 two ends are all tangent with the bellows lateral wall.

The utility model has made full use of air flow operating mode in bellows, creates the deflector position proportioning mode that air flows that is fit to more, has solved the problem of air air quantity maldistribution when turning to by 90 °; And by setting up one in bellows lateral wall corner air flow resistance is reduced, air flows more steady.

Description of drawings

Fig. 1 is a kind of novel burner bellows deflector structure figure.

The specific embodiment

Specify the present invention below in conjunction with embodiment.

Embodiment 1

As shown in Figure 1, be a kind of novel burner bellows deflector structure figure.Described burner wind-box deflector structure is made up of two bellows deflectors, be followed successively by the 1st deflector the 1, the 2nd deflector 2 and arc plate 3 to the outside from the burner wind-box inboard, in the porch, the ratio of the distance between distance, the 2nd deflector and the burner wind-box lateral wall between described distance, the 1st deflector 1 and the 2nd deflector 2 between burner wind-box madial wall and the 1st deflector 1 is 1:1:1;

In the exit, the ratio of the distance between distance, the 2nd deflector and the burner wind-box lateral wall between described distance, the 1st deflector and the 2nd deflector between burner wind-box madial wall and the 1st deflector is 1:1:1.

The two ends of described the 1st deflector, the 2nd deflector are respectively perpendicular to burner wind-box inlet face and exit face, and the middle part is that circular arc is excessive.

The two ends of described arc plate 3 are all tangent with the bellows lateral wall, make that like this enter this regional wind does not produce violent turbulent flow in the corner of bellows, smoothly must enter burner hearth.

Such distribution can make the distribution of air quantity in the bellows be tending towards more evenly, guarantees that the air quantity in exit distributes rationally.

The air quantity that guarantees the exit distributes rationally.

Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.

Claims

1. novel burner bellows deflector structure, it is characterized in that: form by at least two bellows deflectors and an arc plate (3), be followed successively by to the outside from the burner wind-box inboard the 1st deflector, the 2nd deflector ... the n-1 deflector, a n deflector and an arc plate (3), n is the integer more than or equal to 2
