Description
Technical field
The present invention relates to the technical field of boiler system arrangement, specially a kind of boiler supply water deaerating systems.
Background technology
In cogeneration units, when steam turbine outwardly heat supply in a manner of back pressure, the water supply oxygen content of boiler is higher, former
Boiler feedwater by boiler economizer entrance be arranged vacuum deaerating plant deoxygenation, maintain boiler inlet water temperature at 60 DEG C or so,
Vacuum dust cather need to be equipped with vacuum pump to maintain deaerating plant vacuum degree, when feedwater flow is larger or water supply oxygen content is very high,
Maintain the vacuum degree difficulty of oxygen-eliminating device larger, the reliability of system is difficult to ensure.
Invention content
In order to solve the problems, such as existing deoxygenation poor reliability, the present invention provides a kind of boiler supply water deaerating system, energy
Enough realize reliable and stable deoxygenation.
Its technical solution is such：A kind of boiler supply water deaerating system, which is characterized in that it includes heat exchanger, described
The low-temperature receiver import of heat exchanger is passed through water, the import of the low-temperature receiver outlet connection oxygen-eliminating device of the heat exchanger, the interior setting of the oxygen-eliminating device
There are heating tube, the outlet of the oxygen-eliminating device to connect the heat source import of the heat exchanger, the thermal source outlet submitting of the heat exchanger removes
Boiler feedwater after oxygen.
It is further characterized by the heating tube is steam-heating pipe；
It is provided with feed-regulating valve between the heat exchanger and the oxygen-eliminating device；
Feed pump is installed at the thermal source outlet of the heat exchanger.
After system using the present invention, using being heated in the conventional oxygen-eliminating device, heat exchanger and water tank of current technology maturation,
The low-temperature receiver import of heat exchanger, which is passed through 30 DEG C or so of water and exchanges heat to obtain 90 DEG C or so of water by heat exchanger, enters oxygen-eliminating device progress
Deoxygenation, again by heating tube to heating in oxygen-eliminating device, oxygen-eliminating device will be heated after about 120 DEG C water input heat exchanger heat
Source import, the water with 30 DEG C or so are exchanged heat to obtain the boiler feedwater after 60 DEG C or so of deoxygenation, realize reliable and stable remove
Oxygen.
Description of the drawings
Fig. 1 is principle of the invention figure.
Specific implementation mode
As shown in Figure 1, a kind of boiler supply water deaerating system comprising the low-temperature receiver import of heat exchanger 1, heat exchanger 1 is passed through about
30 DEG C of condensed water water supply, the low-temperature receiver outlet of heat exchanger 1 connect the import of oxygen-eliminating device 2 by feed-regulating valve 4, and water temperature reaches at this time
To about 90 DEG C, it is provided with steam-heating pipe 2-2 in the feed-tank 2-1 of oxygen-eliminating device 2, auxiliary deoxygenation is carried out for heating water, 120 DEG C
Outlet of the saturation deaerated water of left and right through oxygen-eliminating device 2 is sent into the heat source import of heat exchanger 1 and is changed with 30 DEG C of condensed water water supply
The thermal source outlet of heat, heat exchanger 1 sends out 60 DEG C of boiler feedwaters after deoxygenation to boiler economizer by feed pump 3.
