The invention relates to a waste steam recovery device for a steelmaking blast furnace, which comprises a tank body. A transverse baffle plate device which can float vertically is arranged inside the tank, the baffle plate device and the tank body are movably connected, a steam inlet pipe, a steam exhaust pipe and an aeration pipe are also arranged on the tank body, the steam inlet pipe and the steam exhaust pipe are arranged below the baffle plate device, the aeration pipe is arranged above the baffle plate device, the baffle plate device adopts a single layer baffle plate structure or a multi-layer baffle plate structure, the baffle plate structure having an upper layer and a lower layer is preferable, the baffle plate and the internal wall of the tank body are movably sealed, the steaminlet pipe is connected to a waste steam discharging pipeline of a waste steam emission source, the steam exhaust pipe is connected to a subsequent waste steam utilizing equipment or a steam pipe utilizing network, and the aeration pipe is directly communicated with atmosphere. The waste steam recovery device converts intermittently discharged waste steam into continuously discharged waste steam with steady pressure, thereby improving the possibility of subsequent utilization of the waste steam, and being mainly used for recycling various intermittently discharged waste steams such as steelmaking blast furnace waste steam.
Description
technical field [0001] The invention relates to a waste steam recovery device of a steelmaking blast furnace, which can be mainly used for recovery and utilization of various intermittently discharged exhaust steam such as the steelmaking blast furnace exhaust steam. Background technique [0002] The exhaust steam emission of steelmaking blast furnaces and other equipment is characterized by large-flow intermittent emissions. Since various exhaust steam recovery devices are mainly designed for continuous exhaust exhaust steam recovery, the exhaust flow needs to be relatively stable, so it is not suitable for intermittent emissions. equipment. Due to the lack of suitable recycling equipment, the exhausted steam discharged intermittently is generally discharged directly into the atmosphere through discharge pipes, resulting in waste of water resources and heat energy. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the p...
