Description

Technical Field

[0001] The utility model relates to the fields of environmental protection device design and environmental protection technology, and specifically refers to a slag flushing steam collection device. Background Art

[0002] During winter production, the slag water system generates a large amount of steam. Especially when there is a lack of large cooling towers and granulation tower slag treatment processes, the steam is emitted in an unorganized manner and diffuses everywhere, greatly affecting the production environment of the blast furnace tapping yard. The vision of the operating workers is greatly affected, causing serious potential safety hazards.

[0003] The steam generated during slag flushing is also extremely corrosive to the surrounding buildings and industrial pipelines of the tapping yard. It often needs to be replaced about once a year, including the color steel tiles on the outer enclosure of the steel structure in the tapping yard and the industrial pipelines, increasing the production maintenance cost.

[0004] The steam diffuses everywhere and also damages the aesthetics of the blast furnace system, greatly affecting the effect of environmental protection production, and urgent treatment is needed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is

[0006] To solve the above problems, the technical solution adopted by the utility model is as follows: The utility model is a slag flushing steam collection device, including an upper air collecting hood. A lower air collecting hood is installed on the upper air collecting hood. The upper air collecting hood and the lower air collecting hood are connected by stainless steel bolts. A hinged manhole is provided on the upper air collecting hood. A stainless steel right-angle elbow penetrates through the right side of the upper air collecting hood, and a stainless steel straight pipe is connected to the stainless steel right-angle elbow.

[0007] Further, the overall framework of the upper air collecting hood and the lower air collecting hood is composed of 12# stainless steel channel steel and 70# stainless steel angle steel.

[0008] Further, the inner cover surfaces of the upper air collecting hood and the lower air collecting hood are welded with 5-mm-thick stainless steel plates.

[0009] Further, the stainless steel bolts adopt the M12 specification.

[0010] Preferably, since the steam generated during slag flushing in the existing slag treatment production process is highly corrosive, both the elbow and the straight pipe adopt the stainless steel 316 material.

[0011] Adopting the above structure, the beneficial effects obtained by the utility model are as follows:

[0012] During the slag discharging process, steam can be collected through the slag flushing steam collection device, reducing the diffusion of steam to the furnace platform, protecting the safety of operating workers, reducing the maintenance costs of the iron-making plant and other attached steel structures, beautifying the blast furnace production environment. The device also uses stainless steel 316 material, significantly extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 FIG. is a schematic structural diagram of a slag flushing steam collection device proposed by the present utility model;

[0014] Figure 2 FIG. is a top view of a slag flushing steam collection device proposed by the present utility model;

[0015] Figure 3 FIG. is a side view of a slag flushing steam collection device proposed by the present utility model.

[0016] Among them, 1 is the lower gas collecting hood, 2 is the stainless steel bolt, 3 is the upper gas collecting hood, 4 is the stainless steel right-angle elbow, 5 is the hinged manhole, and 6 is the stainless steel straight pipe. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figures 1 to 3 shown, the present utility model is a slag flushing steam collection device, including an upper gas collecting hood 3. A lower gas collecting hood 1 is installed on the upper gas collecting hood 3. The upper gas collecting hood 3 and the lower gas collecting hood 1 are connected by stainless steel bolts 2. A hinged manhole 5 is provided on the upper gas collecting hood 3. A stainless steel right-angle elbow 4 penetrates through the right side of the upper gas collecting hood 3, and a stainless steel straight pipe 6 is communicated with the stainless steel right-angle elbow 4.

[0018] The overall frames of the upper gas collecting hood 3 and the lower gas collecting hood 1 are composed of 12# stainless steel channel steel and 70# stainless steel angle steel. The inner covering surfaces of the upper gas collecting hood 3 and the lower gas collecting hood 1 are welded with 5-mm-thick stainless steel plates. The stainless steel bolts 2 adopt the M12 specification.

[0019] During specific use: The slag flushing steam collection device is arranged directly above the slag flushing groove of the blast furnace slag discharging, and can effectively collect the steam generated during slag discharging. A movable hinged manhole 5 is provided above the upper gas collecting hood 3 to prevent the steam hood from bursting when iron explodes in the slag groove. During the slag discharging process, steam can be collected through the slag flushing steam collection device, reducing the diffusion of steam to the furnace platform, protecting the safety of operating workers, and reducing the maintenance costs of the iron-making plant and other attached steel structures.

[0020] It should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
