Abstract
The utility model relates to a kind of spent hot waters of boiler and steam discharge recycling system, demineralized water enters the first injector by booster pump pressurization, high pressure desalination water jet deaerator exhaust enters in the first injector, deaerator exhaust mixes in injector with demineralized water, hot water after heating enters steam-water separator, in steam-water separator after water and oxygen separation, oxygen is discharged from steam-water separator top, separating liquid to the bottom of steam-water separator is discharged, draining enters in the second injector by water circulating pump, and injection is arranged the secondary steam in flash vessel surely and is entered in the second injector, draining and secondary steam enter oxygen-eliminating device recycling together.The steam discharge of injection oxygen-eliminating device carries out secondary recovery utilization and improves Heat Economy of Power Plants so that the heat of oxygen-eliminating device and working medium are recycled well, achievees the purpose that energy-saving；The water being discharged from steam-water separator bottom forms circulation loop by water circulating pump, has effectively accomplished the recycling of working medium.
Description
Technical field
The utility model relates to a kind of heat recovery technology, in particular to the spent hot water of a kind of boiler and steam discharge circulation
Recycling system.
Background technique
Energy-saving and emission-reduction have become the focal issue of current social development, and the spent hot water of heat-engine plant boiler system and steam discharge are direct
Thermal pollution can be caused to atmosphere, destroy ecological environment by being discharged into atmosphere and rivers and lakes, and cause medium-loss and working medium heat
Loss.
Summary of the invention
The utility model is to propose a kind of spent hot water of boiler aiming at the problem that waste energy utilization in heat-engine plant boiler system
Power plant is improved with steam discharge recycling system to recycle the spent hot water and steam discharge that determine in row's flash vessel and oxygen-eliminating device
Economy.
The technical solution of the utility model are as follows: a kind of spent hot water of boiler and steam discharge recycling system, including two
A injector, booster pump, water circulating pump and steam-water separator, demineralized water pressurizes by booster pump enters the first injector, and first
Injector is connect with oxygen-eliminating device, and high pressure desalination water jet deaerator exhaust enters in the first injector, and deaerator exhaust is in injection
Is mixed with demineralized water in device, the hot water after heating enters steam-water separator, in steam-water separator water with after oxygen separation, oxygen
It is discharged from steam-water separator top, the bottom discharge of separating liquid to steam-water separator, draining enters second by water circulating pump
In injector, and injection is arranged the secondary steam in flash vessel surely and is entered in the second injector, and draining and secondary steam enter together
Oxygen-eliminating device recycling.
The utility model has the beneficial effects that: spent hot water and the steam discharge recycling system of the utility model boiler
The steam discharge of system, injection oxygen-eliminating device carries out secondary recovery utilization, so that the heat of oxygen-eliminating device and working medium are recycled well,
Heat Economy of Power Plants is improved, is achieved the purpose that energy-saving；The water being discharged from steam-water separator bottom, passes through water circulating pump shape
At circulation loop, the recycling of working medium is effectively accomplished.
Detailed description of the invention
Fig. 1 is spent hot water and the steam discharge recycling system structure diagram of the utility model boiler.
Specific embodiment
The spent hot water of boiler as shown in Figure 1 and steam discharge recycling system structure diagram, demineralized water pass through desalination
Jellyfish pipe 1 enters the first injector 3 by the pressurization of booster pump 2, and the first injector 3 is connect with oxygen-eliminating device 8, and the first injector utilizes
8 steam discharge of high pressure desalination water jet oxygen-eliminating device enters in the first injector 3, and 8 steam discharge of oxygen-eliminating device mixes in injector with demineralized water,
Be heated to demineralized water, steam discharge is condensed into water, and the hot water after heating enters steam-water separator 4, in steam-water separator 4 water with
Oxygen is separated, and oxygen is discharged from 4 top of steam-water separator, and the bottom position of separating liquid to steam-water separator 4 agglomerates row
Out, circulation loop is formed by water circulating pump 5, is drained into the second injector 6 and recycles again, injection arranges flash vessel surely
Secondary steam in 7 enters in the second injector 6, and draining and secondary steam enter 8 recycling of oxygen-eliminating device together.Depending on
Spent hot water and steam discharge caused by row's flash vessel and oxygen-eliminating device and heat therein are recycled, and boiler system is improved
The thermal efficiency and Heat Economy of Power Plants of system, achieve the purpose that energy-saving.
