Background
The gas collecting hood is a device for directly collecting pollution sources by a smoke and dust gas purification system, and has the function of collecting dust and gas pollution sources and then guiding the collected dust and gas pollution sources into a special purification system to prevent the dust and gas pollution sources from diffusing into a production workshop and the atmosphere to cause pollution. The performance of the system has direct influence on the technical and economic indexes of the purification system, and also has great relation to environmental protection, occupational hazards of operators and the like. Due to the difference of the structure of the pollution source equipment and the production operation process, the forms of the gas collecting hood are also various.
The gas-collecting hood of the traditional electrolytic furnace adopts an upward drawing type and has two types of fixed gas-collecting hoods and lifting gas-collecting hoods. The fixed gas collecting hood is generally higher in installation position, generally more than 2 meters, and much smoke dust of the electrolytic furnace is dissipated; although the lifting gas collecting hood can be relatively close to an electrolytic furnace, the dust collecting effect is good, the operations of stirring the furnace, discharging the furnace, replacing an anode and the like by staff are prevented, when the staff performs the operations, the gas collecting hood must be lifted to a high position, and the dust collecting effect is poor. When the staff is close to the electrolytic furnace for operation, better environment is needed to protect the health of the staff, but the two up-drawing gas collecting hoods have obvious disadvantages. On the other hand, the flying loss of the electrolytic raw material is large, and the recovery rate of the rare earth is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems in the prior art to a certain extent and provides a novel side-drawing type electrolytic furnace smoke and dust collecting hood.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
for overcoming the technical defects that the dust collecting effect of the upper drawing type gas collecting hood of the existing electrolytic furnace is poor and the protection to the operating environment of the staff is not good, the utility model discloses a novel side drawing type smoke dust gas collecting hood of the electrolytic furnace.
A novel side-drawing type electrolytic furnace smoke and dust collecting hood comprises:
the gas collecting hood body is horn-shaped and is arranged above the side of the furnace opening of the electrolytic furnace and faces the furnace opening of the electrolytic furnace;
the air exhaust pipeline comprises a horizontal section and a vertical section which are integrally formed, and the end part of the horizontal section is connected with the narrow-mouth end of the gas collecting hood body;
the vertical pipeline, the bottom of vertical pipeline is provided with the swivel line head, the swivel line head with the end connection of vertical section, the top and the flue gas trunk line intercommunication of vertical pipeline.
Further, the gas collecting hood body is 15-25cm above the furnace mouth of the electrolytic furnace.
Furthermore, an included angle of 13-18 degrees is formed between the horizontal section of the air draft pipeline and the horizontal direction.
The beneficial effect who adopts above-mentioned scheme is, reaches better convulsions effect.
Furthermore, a flap type wind power regulating valve is installed in the air suction pipeline.
The beneficial effect who adopts above-mentioned scheme is that, rotates the flap that is located the suction line as required, adjusts the draft size or closes the pipeline completely.
Through foretell technical scheme, compare with prior art, the utility model discloses possess following advantage:
1. the gas collecting hood is close to the smoke outlet, the smoke and dust collecting efficiency is high, the flying loss of materials is reduced, and the recovery rate of the electrolytic rare earth is improved.
2. The gas-collecting hood does not affect any operation of the electrolytic furnace above the side of the electrolytic furnace, can continuously collect smoke dust, has the dust collection rate of 96.5 percent, and greatly improves the operating environment of workers.
3. The direction of the gas collecting hood can be flexibly adjusted by rotating the pipeline joint.
4. The volume of the gas-collecting hood is smaller, and the cost is saved.
