Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] The gas dispersing device disclosed in the embodiment of the present invention can disperse the gas more safely, preheat the gas and air, reduce the gas flow rate, make the combustion more complete, and avoid the situation of flameout and flameout.

[0022] Such as figure 1 and figure 2 As shown, a gas release device mainly includes an inner cylinder 1 and an outer cylinder 2, the inner cylinder 1 is arranged vertically, the lower end of the inner cyl...

Abstract

The invention discloses a gas diffusion device. The gas diffusion device comprises an inner cylinder and an outer cylinder surrounding the periphery of the inner cylinder. Spacing exists between the inner wall of the outer cylinder and the outer wall of the inner cylinder, and a first annular partition plate and a second annular partition plate in the circumferential direction of the inner cylinder are arranged on the outer wall of the inner cylinder at intervals in the axial direction from bottom to top. The circumferential peripheries of the first partition plate and the second partition plate are connected to the inner wall of the outer cylinder, and the first partition plate and the second partition plate are provided with through holes. A first combustion chamber is arranged at an area between the first partition plate and the second partition plate, and a second combustion chamber is arranged at the position, above the second partition plate, in the outer cylinder. The first combustion chamber is internally provided with first burners and second burners at intervals from bottom to top in the axial direction of the inner cylinder, the first burners are connected with a blast furnace gas pipe and maintained in a normally open flame state, and the second burners are in communication with the inner cylinder through branch pipes. The gas diffusion device can enable diffused gas to be reliably ignited, can preheat the gas and air, improves the sufficiency of combustion, and avoids the situations of flame lifting and flameout.

Description

technical field [0001] The invention relates to the technical field of gas release, in particular to a gas release device. Background technique [0002] Most of the gas release tower structures used by iron and steel enterprises in ironmaking are to install a gas release torch on the top of the release tower, and most of the burners are equipped with swirlers to mix gas and air through the swirler to achieve full combustion. The effect; through the actual use effect, the release ability of this combustion method is very limited, and the overall release effect is not ideal. When the amount of gas released is large, it is prone to flameout and flameout. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to improve the existing technology and provide a gas release device to solve the problem that the release tower in the current technology is prone to flameout and flameout when the amount of gas r...
