Description

A kind of power plant boiler water oxygen-eliminating device heat reclaim unit
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
Fig. 1 is power plant boiler water deaerator device schematic illustration in the prior art.
Fig. 2 is the principles of the present invention schematic diagram.
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.
