Description

Technical fields:

[0001] This utility model belongs to the field of smoke and dust treatment, and in particular relates to a smoke and dust turbulence device for silicon-manganese alloy production. Background technology:

[0002] In the production of silicon-manganese alloys, the fumes generated by the electric furnace need to be further transported to a purification system for treatment. Dust removal is the first step in fume treatment. High-efficiency dust collectors, such as bag filters or electrostatic precipitators, can effectively remove dust particles from the flue gas and reduce air pollution.

[0003] In the existing process, the exhaust fan introduces the smoke and dust into the smoke duct at high speed and then transports it to the bag filter. The particulate matter carried in the smoke and dust impacts the outer surface of the filter bag at high speed, resulting in severe wear on the outer surface of the filter bag after long-term use. This leads to a decrease in the smoke and dust filtration effect, frequent shutdowns and maintenance of the smoke and dust purification system, and the inability to continuously produce silicon-manganese alloy. Summary of the Invention:

[0004] The purpose of this utility model is to provide a dust turbulence device for the production of silicon-manganese alloys, and to overcome the shortcomings of the prior art. It effectively solves the existing problem of frequent damage to dust removal equipment caused by the high dust flow rate.

[0005] The present invention relates to a dust turbulence device for the production of silicon-manganese alloys, comprising a smoke guide pipe, a frame frame spanning across the inner cavity of the smoke guide pipe, a corrugated plate laid on the frame frame, and a plurality of air guide holes evenly formed along the length direction on both sides of the crest of the corrugated plate.

[0006] Furthermore, the opening angle of the air guide hole is inclined upward.

[0007] Furthermore, an installation port matching the frame is provided on the side wall of the smoke guide pipe, and the frame is inserted into the installation port.

[0008] Furthermore, sliding strips matching the mounting opening are installed on both sides of the inner cavity of the smoke guide tube.

[0009] Furthermore, a sealing plate matching the mounting opening is installed at the outer end of the frame.

[0010] Furthermore, a handle is installed at the outer end of the sealing plate.

[0011] Furthermore, a sealing ring is fitted onto the outer edge of the sealing plate.

[0012] The beneficial effects of this utility model are: its structure is simple and easy to install. By adding a guide corrugated plate inside the smoke duct, the flow speed of the smoke and dust is reduced, the wear on the surface of the dust collector bag is reduced, and the dust filtration effect of the bag filter is improved.

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 3 As shown, a dust turbulence device for the production of silicon-manganese alloy includes a smoke guide pipe 1, a frame 2 is arranged across the inner cavity of the smoke guide pipe 1, a corrugated plate 3 is laid on the frame 2, and a plurality of air guide holes 4 are evenly opened along the length direction on both sides of the crest of the corrugated plate 3, and the opening angle of the air guide holes 4 is inclined upward.

[0019] Specifically, by installing a guide corrugated plate 3 inside the smoke guide pipe 1, the flow direction of the smoke and dust is changed, and the flow speed of the smoke and dust is reduced.

[0020] In actual use, the high-speed flowing smoke and dust in the smoke guide pipe 1 comes into contact with the corrugated plate 3. At this time, the neatly arranged crests of the corrugated plate 3 guide the smoke and dust evenly to both sides. The smoke and dust flow along the crests to the bottom of the troughs, and then rise along the crests on the other side, and flow into the other side of the corrugated plate 3 through the air guide holes 4. This turbulence process forces the flow speed of the smoke and dust to slow down, thereby reducing the direct impact force of the particulate matter in the smoke and dust on the filter bag. The opening angle of the air guide holes 4 is inclined upward, which makes it easier for the smoke and dust to enter the air guide holes 4 when it flows back through the troughs. This allows the smoke and dust to flow more accurately into the air guide holes 4 while reducing the flow rate, thereby ensuring that the flow rate of the smoke and dust is not affected.

[0021] like Figures 1 to 3As shown, a dust turbulence device for the production of silicon-manganese alloy has an installation port 5 on the side wall of the smoke guide pipe 1 that matches the frame 2. The frame 2 is inserted into the installation port 5. Slide strips 6 that match the installation port 5 are installed on both sides of the inner cavity of the smoke guide pipe 1. A sealing plate 7 that matches the installation port 5 is installed on the outer end of the frame 2. A handle 8 is installed on the outer end of the sealing plate 7. A sealing ring is fitted on the outer edge of the sealing plate 7.

[0022] Specifically, the installation port 5 opened on the side wall of the smoke guide pipe 1 allows the turbulence device to be quickly installed and removed.

[0023] In actual use, the staff can insert the frame 2 into the installation port 5, and the slide bar 6 can further guide the sliding direction of the frame 2 to prevent deviation. When the inner end of the frame 2 is in contact with the inner wall of the flue duct 1, the sealing plate 7 installed at the outer end of the frame 2 is perfectly matched and embedded in the installation port 5, thereby preventing the flue gas from leaking out of the installation port 5. When the flue gas purification system is shut down for maintenance, the handle 8 can be pulled to quickly remove the frame 2 from the flue duct 1, thereby maintaining the corrugated plate 3.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
