Description
Technical field
The utility model relates to generating equipment technical field, in particular to a kind of power plant boiler is returned with water oxygen-eliminating device heat
Receiving apparatus.
Background technique
It when prior art steam-electric power, needs to inject water into boiler, water is heated into steam and drives steam turbine acting,
The water being injected into boiler must get rid of salt and oxygen in water in advance, if oxygen do not remove it is clean if, meeting and boiler
Or steam turbine reaction, the normal work of boiler and steam turbine is influenced, reduces its working efficiency, while can also waste fossil fuel.
Fig. 1 is deaerating plant in the prior art, and the water for removing salinity gets off from oxygen-eliminating device top spray, heating steam from
The bottom of oxygen-eliminating device flows up, and heats to the water sprayed except supersalt, decomposites oxygen and comes, the steam after reaction
It is expelled in atmosphere from gland steam exhauster, the heating steam being discharged from gland steam exhauster still has higher temperature, and discharge causes like this
The waste of the energy, the increase of cost, and be unfavorable for protecting environment.
Summary of the invention
Purpose of the utility model is to solve the deficiencies in background technique, provide a kind of power plant boiler water deoxygenation
Device heat reclaim unit, the utility model can re-use the heating steam being expelled in atmosphere, save fossil fuel, drop
Low production cost, reduces the discharge of carbon dioxide, protects ecological environment.
A kind of power plant boiler water oxygen-eliminating device heat reclaim unit, including steam inlet pipe, oxygen-eliminating device, water inlet pipe, heat exchanger,
First drainpipe, return pipe, gland steam exhauster, valve and the second drainpipe, water inlet pipe passes through heat exchanger and is connected to oxygen-eliminating device, into vapour
Pipe, gland steam exhauster and the second drainpipe are connected to oxygen-eliminating device respectively, and return pipe is connected between gland steam exhauster and heat exchanger, on heat exchanger
It is provided with the first drainpipe, valve is arranged between the outlet of gland steam exhauster and return pipe.
The working principle and use process of the utility model:
Valve is closed, heating steam is flow to inside oxygen-eliminating device by steam inlet pipe, and the water after desalination is passed through by water inlet pipe
Heat exchanger is flow to inside oxygen-eliminating device, and from the sprinkling downwards of oxygen-eliminating device top, heating steam is to the water sprayed downwards at the top of oxygen-eliminating device
It heats up, its oxygen is decomposed away, the water after desalination deoxygenation is expelled in water tank or boiler from the second drainpipe, is removed
Steam after oxygen device internal-response is discharged along gland steam exhauster through in return line flow to heat exchanger, to the water after the desalination of water inlet pipe inside
It heats up, heats steam and be discharged after heat exchanger internal condensation by the first drainpipe, the presence of heat exchanger can be right in advance
The water after desalination inside water inlet pipe is tentatively heated up, and has been saved the usage amount of follow-up steam, has been saved the energy, has protected ring
Border makes resources.
The utility model has the beneficial effects that
The utility model structure is simple, easy to use, the presence of heat exchanger can in advance to the desalination inside water inlet pipe after
Water tentatively heated up, saved the usage amount of follow-up steam, saved the energy, reduced costs, protected environment, made to provide
Source sustainable use.
Detailed description of the invention

Specific embodiment
It please refers to shown in Fig. 2, a kind of power plant boiler water oxygen-eliminating device heat reclaim unit, including steam inlet pipe 1, oxygen-eliminating device
2, water inlet pipe 3, heat exchanger 4, the first drainpipe 5, return pipe 6, gland steam exhauster 7, valve 8 and the second drainpipe 9, water inlet pipe 3 pass through
Heat exchanger 4 is connected to oxygen-eliminating device 2, and steam inlet pipe 1, gland steam exhauster 7 and the second drainpipe 9 are connected to oxygen-eliminating device 2 respectively, and return pipe 6 connects
It connects between gland steam exhauster 7 and heat exchanger 4, the first drainpipe 5 is provided on heat exchanger 4, the discharge of gland steam exhauster 7 is arranged in valve 8
Between mouth and return pipe 6.
The working principle and use process of the present embodiment:
It please refers to shown in Fig. 2, valve 8 is closed, heating steam is flow to inside oxygen-eliminating device 2 by steam inlet pipe 1, after desalination
Water passes through heat exchanger 4 by water inlet pipe 3 and flow to inside oxygen-eliminating device 2, and from the sprinkling downwards of the top of oxygen-eliminating device 2, heating steam is to from removing
The water that the top of oxygen device 2 is sprayed downwards heats up, its oxygen is decomposed away, and the water after desalination deoxygenation is from 9 row of the second drainpipe
Heat exchange is flow to through return pipe 6 in water tank or boiler, the steam after 2 internal-response of oxygen-eliminating device is discharged along gland steam exhauster 7 out
It in device 4, heats up to the water after 3 inside desalination of water inlet pipe, heats steam after 4 internal condensation of heat exchanger by the first draining
Pipe 5 is discharged, and the presence of heat exchanger 4 in advance can tentatively heat up to the water after the desalination inside water inlet pipe 3, save subsequent
The usage amount of steam, has saved the energy, protects environment, makes resources.
