CN203146437U - Rectifier grid - Google Patents

Abstract

The utility model relates to a rectifier grid comprises a shell, guide plates and support plates. The rectifier grid is characterized in that the guide plates are mounted on the inner wall of the shell horizontally, and the support plates are vertically mounted between the guide plates and staggered; and when fluid enters the bend tube of a blast furnace air blower tube, the fluid can pass through stably and sequentially by guiding of the guide plates, influence caused by air flow to air blower blades and energy loss of the air flow caused by turning are reduced, and meanwhile, turbulent flow caused by unevenly distributed fluid can be avoided effectively. By the aid of the rectifier grid, safe production of a blast furnace is guaranteed effectively, and yield of the blast furnace is increased effectively; and meanwhile, the appearance of the rectifier grid can be designed according to tube section shape, and the rectifier grid has the advantages of simple structure, convenience in mounting and the like.

Description

Honeycomb

Technical field:

The utility model relates to a kind of equipment that is used on the blast furnace blower inlet pipe, and is particularly a kind of be used to making air-flow honeycomb stably.

Background technique:

Along with improving constantly of ironmaking technology, the capacity of blast furnace blower is also increasing, and when the air-flow that enters blower is not steady, blower will increase to the pressure of blast furnace air-supply, form turbulent flow easily; When particularly fluid is by bend, because the factors such as variation, fluid skewness that flow to can not steadily be passed through air-flow in an orderly manner, thereby increase the interference of air-flow to blower vane, caused energy loss, reduced furnace processor.

The model utility content:

The purpose of this utility model be to provide a kind of simple in structure, can make fluid can be steadily the honeycomb by blower conduits in order.

To achieve these goals, the utility model proposes following technological scheme realizes:

Honeycomb is made up of housing, guide plate, dunnage; It is characterized in that: the guide plate level is installed on the inner walls, is vertically installed with dunnage between the guide plate, and dunnage is staggered.

The soluble technical problem of the utility model is: when fluid enters the bend of pipeline, after the guide plate guiding, can steadily pass through in an orderly manner, this has just reduced air-flow owing to turn to the energy loss brought and the flow resistance of pipeline, avoided the turbulent flow because of reason formation such as fluid skewness, flow direction variations simultaneously, to improving blast furnace production capacity and safety in production very important meaning has been arranged; The profile of honeycomb can be according to the Cross section Design of pipeline simultaneously, and guide plate also can be pressed into required shape according to the characteristics that fluid passes through, and makes air-flow fully by bend, has advantages such as simple in structure, easy for installation.

Description of drawings:

Fig. 1 is the utility model structural drawing;

Fig. 2 is the utility model scheme of installation;

Embodiment:

As shown in Figure 1, honeycomb is made up of housing 1, guide plate 2, dunnage 3; It is characterized in that: guide plate 2 levels are installed on the inwall of housing 1, are vertically installed with dunnage 3 between the guide plate 2, and dunnage 3 is staggered.

As shown in Figure 2, during enforcement, profile according to the Cross section Design honeycomb of pipeline, the characteristics of passing through according to fluid are pressed into the guide plate 2 of required form, honeycomb directly is welded on the pipeline, when fluid enters the bend of blower conduits, after guide plate 2 guiding, can steadily passes through in an orderly manner, effectively reduced air-flow owing to turn to the pressure loss brought and the flow resistance of pipeline, to improving blast furnace production capacity and safety in production very important meaning arranged; Also has advantage simple in structure, easy for installation simultaneously.

Claims (1)

1. honeycomb is made up of housing, guide plate, dunnage; It is characterized in that: the guide plate level is installed on the inner walls, is vertically installed with dunnage between the guide plate, and dunnage is staggered.
