Description

Technical Field

[0001] The present application relates to the technical field of slag flushing of smelting furnaces, and in particular to a steam discharge device of a slag flushing system of a smelting furnace. Background Art

[0002] A smelting furnace refers to a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloys through operations such as slagging and refining. During the slag flushing process of the smelting furnace, a large amount of steam will be generated. The existing slag flushing system of the smelting furnace uses water to spray water vapor, condense the steam, and return the condensed water to the slag flushing pool, and then transport it to the cooling tower together with the water in the slag flushing pool for cooling, but this method consumes a lot of water for spraying water. Alternatively, a simple discharge port is used to discharge steam, but due to the small discharge port, the steam discharge speed is slow, resulting in low discharge efficiency. Since the steam contains a large amount of harmful substances, direct discharge into the atmosphere will cause pollution to the environment; and the steam is directly discharged without recycling, resulting in energy waste.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

A water outlet pipe 5 is provided at the top of the other side of the steam recovery device 1 for discharging water after recovering waste heat for subsequent use. A steam discharge tank 9 is fixed to the middle of the inner wall of the steam recovery device 1. A serpentine steam pipe 12 is provided inside the steam discharge tank 9. Sealing pipes 13 are fixedly connected to both ends of the serpentine steam pipe 12. The two sealing pipes 13 extend to the inside of the air inlet pipe 7 and the exhaust pipe 4 respectively. Therefore, hot steam can be introduced into the inside of the serpentine steam pipe 12 through the sealing pipe 13.
