Description
Technical field
The utility model relates to the technical field of boiler system arrangement, specially a kind of boiler supply water deaerating systems.
Background technique
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.
Summary of the invention
In order to solve the problems, such as existing deoxygenation poor reliability, the utility model provides a kind of boiler supply water deaerating system,
It can be realized 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 cold source import of heat exchanger is passed through water, the import of the cold source outlet connection oxygen-eliminating device of the heat exchanger, the interior setting of the oxygen-eliminating device
There is heating tube, the outlet of the oxygen-eliminating device connects the heat source import of the heat exchanger, and 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；
Feed-regulating valve is provided between the heat exchanger and the oxygen-eliminating device；
Feed pump is installed at the thermal source outlet of the heat exchanger.
After the system of the utility model, add using in the conventional oxygen-eliminating device, heat exchanger and water tank of current technology maturation
Heat enters oxygen-eliminating device by the water that heat exchanger exchanges heat to obtain 90 DEG C or so in the water that the cold source import of heat exchanger is passed through 30 DEG C or so
Deoxygenation is carried out, again by heating tube to heating in oxygen-eliminating device, about 120 DEG C of water input heat exchanger after oxygen-eliminating device will be heated
Heat source import, the water with 30 DEG C or so exchanged heat to obtain the boiler feedwater after 60 DEG C or so of deoxygenation, and realizing stabilization can
By deoxygenation.
Detailed description of the invention
Fig. 1 is the utility model principle figure.
Specific embodiment
As shown in Figure 1, a kind of boiler supply water deaerating system comprising the cold source import of heat exchanger 1, heat exchanger 1 is passed through about
30 DEG C of condensed water water supply, the cold source 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, carries out auxiliary deoxygenation for heating water, 120 DEG C
The heat source import of outlet feeding heat exchanger 1 of the saturation deaerated water of left and right through oxygen-eliminating device 2 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.
