Description

Technical Field

[0001] The utility model relates to the technical field of thermal deaerators, in particular to a high-performance exhaust steam recovery device for a thermal deaerator. Background Art

[0002] Thermal deaerator (rotating film deaerator) is a new type of deaerator, which can remove dissolved oxygen and other gases in the feed water of thermal system and prevent corrosion of thermal equipment. It is an important equipment to ensure the safe operation of power plants and industrial boilers. It can be used for constant pressure, sliding pressure, negative pressure and other modes of operation. It has the characteristics of allowing high dissolved oxygen content in inlet water, low inlet water temperature, large feed water volume, etc. It is suitable for deoxygenation of water used in various power station boilers, industrial boiler feed water and thermal power plant feed water.

[0003] Thermal deaerator exhaust steam refers to the part of the steam mixture produced in the thermal deaerator process that is not effectively utilized and is discharged.

[0004] The inventors have found in their daily work that when existing thermal deaerators generate exhaust steam during operation, most of them are usually discharged directly, resulting in a large amount of exhaust steam waste. At the same time, some recovery devices use a pump body to suck the exhaust steam into the heat exchanger during recovery, and conduct the heat energy through the heat exchanger. As the exhaust steam flows through multiple processes, the heat of the exhaust steam is easily reduced, resulting in low utilization rate, and the liquid in the exhaust steam cannot be collected, which leads to the problem of low exhaust steam utilization rate of existing recovery devices and a large amount of heat waste in the middle.

By setting up a collection device, it is convenient to make high-performance utilization of exhaust steam, and the exhaust steam generated by the thermal deaerator can be recovered to the maximum extent to insulate the deaerator. At the same time, the moisture in the exhaust steam can be collected, which can effectively reduce the existing thermal deaerator. When exhaust steam is generated, it is usually directly discharged, resulting in a large amount of exhaust steam waste. At the same time, some recovery devices use a pump body to draw the exhaust steam into the heat exchanger during recovery, and conduct the heat energy through the heat exchanger, resulting in the exhaust steam When the exhaust steam flows in multiple processes, the heat of the exhaust steam is easily reduced, resulting in low utilization rate, and the liquid in the exhaust steam cannot be collected, thereby improving the overall practicality of the equipment.

Subsequently, the exhaust steam is discharged into the collection box 44 through the exhaust pipe 42, and the absorbent cotton 412 absorbs the moisture in the exhaust steam.

[0026] Specifically, a heat insulating member 413 is installed on the inner wall of the deaerator body 1, and the heat insulating member 413 can protect the heat of the conduction pipe 43 and the inner wall of the deaerator body 1, thereby improving the heat preservation effect.

[0034] Working principle: When the thermal deaerator is used, it is mainly used to remove dissolved oxygen and other gases in the feed water of the thermal system to prevent corrosion of the thermal equipment. By setting up a collecting device 4, when exhaust steam is generated in the deaerator body 1, the exhaust steam is discharged from the outlet 3, and the air inlet pipe 41 can conduct the exhaust steam to the conduction pipe 43. Since the spiral tube 1 431 and the spiral tube 2 432 are evenly entangled with the inner wall of the deaerator body 1, the heat in the exhaust steam can be evenly transmitted to the inner wall of the deaerator body 1 through the spiral tube 1 431 and the spiral tube 2 432 in the conduction pipe 43, thereby utilizing the exhaust steam to keep the deaerator body 1 warm. The thermal insulation 413 can well isolate the heat. Then the exhaust steam is discharged into the collection box 44 through the exhaust pipe 42, and the absorbent cotton 412 absorbs the moisture in the exhaust steam. When the absorbent cotton 412 absorbs too much moisture, it will drip into the collection box 46 for collection, and it can be pushed The pressing block 451 and the pressing rod 452 are movable, and the spring 453 is stressed. The pressing plate 454 is on the absorbent cotton 412. The pressing plate 454 cooperates with the support plate 411 to squeeze the absorbent cotton 412, and squeezes the moisture into the collection box 46 for collection. By setting up the collecting device 4, it is convenient to make high-performance utilization of the exhaust steam, and the exhaust steam generated by the thermal deaerator can be recovered to the maximum extent to keep the deaerator warm. At the same time, the moisture in the exhaust steam is collected, which can effectively reduce the existing thermal deaerator. When exhaust steam is generated, it is usually directly discharged, resulting in a large amount of exhaust steam waste. At the same time, some recovery devices use a pump body to draw the exhaust steam into the heat exchanger during recovery, and conduct the heat energy through the heat exchanger, resulting in the exhaust steam When the exhaust steam flows in multiple processes, the exhaust steam heat is easily reduced, resulting in low utilization rate, and the liquid in the exhaust steam cannot be collected, thereby improving the overall practicality of the equipment.
