Description

Technical Field

[0001] The invention relates to the technical field of exhaust steam recovery, in particular to an exhaust steam recovery device for a boiler room. Background Art

[0002] Exhaust steam refers to steam that has done work and is discharged from equipment such as steam engines and steam turbines. After driving the rotor of the equipment to rotate, this steam releases thermal potential energy and is then discharged from the exhaust port of the equipment. In the boiler room, industrial boilers, power station boilers and other equipment will generate a large amount of low-pressure steam and flash steam (i.e., exhaust steam) during operation. If it is discharged directly into the air, it will cause energy loss and waste.

[0003] Steam heat exchangers play a vital role in the exhaust steam recovery process. Conventional steam heat exchangers perform heat exchange operations through steam and cooling water circulating inside the cooling water pipe. In this process, the steam condenses into water after heat exchange, and then is smoothly discharged from the steam trap at the bottom of the heat exchanger. However, after long-term operation, the inner and outer walls of the cooling water pipe are prone to scale accumulation. This not only forms a difficult-to-remove liquid film on the surface of the pipe when the condensed water condenses, thereby hindering the heat exchange efficiency, but also the contact interface between the pipe and the exhaust steam is small, and conventional recovery equipment is not convenient for pressurizing the exhaust steam to a certain extent, resulting in poor heat recovery effect, thereby weakening the heat recovery effect.

[0004] Therefore, how to effectively deal with the scaling problem of cooling water pipes and optimize the contact interface between pipes and exhaust steam becomes the key to improving exhaust steam recovery efficiency. Summary of the invention
