Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and give detailed implementation manners and specific working procedures, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the flue gas collection and purification system for a foundry ladle according to the present invention includes a collection cover 1, a fan 2, a dust collector 3, and the like. The collecting cover 1 is positioned above the ladle M, is in a cone-like shape with a sandwich structure, and is used for collecting flue gas generated in the processes of ladle repair, ladle baking, slag skimming, molten iron conveying and the like of the ladle. Specifically, the center of the trapping cover 1 is provided with a flow passage 101 which is communicated up and down, the inlet end at the bottom of the trapping cover is of a flaring structure with a downward opening, and the top of the trapping cover is an outlet end; the outer interlayer of the overflowing channel 101 is provided with an air inlet hole (namely an inlet end) on the side surface and a jet orifice (namely an outlet end) at the bottom to form a circulating air flow passage 102, the jet orifices of the circulating air flow passage 102 are arranged in the annular direction or are a plurality of nozzles arranged in the annular direction, the air flow sprayed out of the nozzles is the same as the inclination angle of a flaring structure at the bottom of the overflowing channel 101, an annular air curtain for covering a ladle is formed, and dust-containing smoke is prevented from escaping. Because the air curtain is an external expanding annular structure, the trapping cover 1 is small in size, the manufacturing cost is saved, the self weight can be reduced, and the air curtain is convenient to hoist. Normally, a support frame 4 is mounted on one side of the ladle, and a translation hoisting mechanism driven by an electric hoist is arranged on the support frame, and a lifting rope of the translation hoisting mechanism is connected with the top of the trapping cover 1. In order to simplify the work of installing the connection duct in accordance with the adjustment of the installation position of the collecting cover 1, the outlet duct of the flow passage 101 and the outlet duct of the circulating air flow passage 102 are connected to the horizontal spring duct 5. The outlet pipe of the outlet end of the flow passage 101 is connected with the inlet pipe of the fan 2, the outlet pipe of the fan 2 is connected with a first branch pipe 201 and a second branch pipe 202, wherein the first branch pipe 201 is communicated with the air inlet pipe of the inlet end of the circulating air flow passage 102, the second branch pipe 202 is connected with the inlet end of the dust remover 3, and the outlet end of the dust remover 3 is communicated with the external environment through the exhaust chimney 6.
When the device works, the fan 2 is started, the ladle smoke enters the overflowing channel 101 from the bottom flaring structure of the collecting cover 1 and then enters the fan 2 from the outlet end, wherein most of gas returns to the collecting cover 1, enters the circulating air flow channel 102 from the first branch pipe 201 at the outlet end of the fan 2, and forms an annular air curtain for covering the ladle through the annular jet orifice at the outlet end at the bottom so as to prevent the dust-containing smoke from escaping in the collecting process; the other small part of the gas at the outlet of the fan 2 enters the dust remover 3 through the second branch pipe 202, and is discharged after reaching the standard through the exhaust chimney 6 after dust removal and purification.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
