Abstract
The utility model relates to a cooling system of a vacuum refining furnace. The cooling system is characterized in that the system comprises a gas guide pipe connected with a waste gas exhaust port of a vacuum chamber of the refining furnace, a cooling pipe sleeve is sheathed outside the gas guide pipe, a plurality of ventilation holes are formed in the pipe wall of the cooling pipe sleeve, the ventilation holes are connected to a cold air blower, and the output end of the gas guide pipe is connected to an exhaust chimney. After the technical scheme is adopted, waste gas which is vaporized in the gas guide pipe is re-cooled and solidified through cold air and then filtered away by a filter screen, so that the probability of exhausting the waste gas into the atmosphere is reduced and the air pollution is reduced.
Description
Technical field
The utility model belongs to the refining furnace field, is specifically related to a kind of cooling system of vacuum refining furnace.
Background technology
In field of metallurgy, RH refers to monoblock type or split type vacuum chamber, when handling molten steel, so metallurgical reaction all carries out in this vacuum chamber, the all gases that produces in the metallurgical reaction process is extracted out in the vacuum chamber by vacuum-pumping system through the hot bending pipe and is entered atmosphere, yet refining furnace itself is in order to obtain the more pure steel of high-quality, namely need to carry out desulfurization and slag absorption work, remove harmful inclusion, but also be that inclusion also might be vaporized and is discharged in the atmosphere polluted air then.
Summary of the invention
The utility model then provides a kind of cooling system of vacuum refining furnace in order to solve the technical problem of mentioning in the background technology.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of cooling system of vacuum refining furnace, it is characterized in that: native system comprises an airway that is connected with refining furnace vacuum chamber waste discharge gas port, described airway is with the cooling tube cover outward, described cooling tube casing wall is provided with some ventilating pits, described ventilating pit connects to cold blast engine, and the output terminal of described airway connects to gas shaft.
The output terminal end face of described airway is provided with one deck filtering net.
After adopting above technical scheme:, be filtered net filtration then again and fall the curing of lowering the temperature again of the waste gas that is vaporized in the airway by cold wind, then can reduce the probability that enters atmosphere, reduce the pollution of air.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of cooling system of vacuum refining furnace, comprise an airway 2 that is connected with refining furnace vacuum chamber waste discharge gas port 1, the described airway 2 outer cooling tube covers 3 that are with, described cooling pipe box 3 tube walls are provided with some ventilating pits 4, described ventilating pit 4 connects to cold blast engine, and the output terminal of described airway 2 connects to gas shaft 5.The output terminal end face of described airway 2 is provided with one deck filtering net.
After adopting above technical scheme:, be filtered net filtration then again and fall curings of lowering the temperature again of the waste gas that are vaporized in the airway 2 by cold wind, then can reduce the probability that enters atmosphere, the pollution of minimizing air.
