Abstract
The invention provides a self-heating type deaerator with a heat exchanger. The self-heating type deaerator comprises a thermal deaerator (1) and further comprises the heat exchanger (2). The heat exchanger (2) comprises a cold water inlet (21), a cold water outlet (22), a hot water inlet (23) and a hot water outlet (24). A water supplementing port (13) of the thermal deaerator is connected with the cold water outlet (22). A water outlet (14) of the thermal deaerator is connected with the hot water inlet (23). The hot water outlet (24) of the heat exchanger is connected with a boiler system. When the self-heating type deaerator with the heat exchanger is operated, high-temperature deaeration water drained from the water outlet (14) of the thermal deaerator preheats water to be deaerated through the heat exchanger (2) to increase the temperature of the water to be deaerated, the steam amount required for heating deaeration is reduced, and meanwhile the high-temperature deaeration water is cooled through the heat exchanger (2), so that the efficiency of following operation of the boiler system is improved.
Description
Technical field
The present invention relates to a kind of thermal deaerator, particularly a kind of self-heating oxygen-eliminating device with heat exchanger.
Background technology
Oxygen-eliminating device is one of key equipment of boiler and other heating systems, and it can remove the dissolved oxygen in water needed for heating system, prevents its corrosion heating equipment.Domestic common thermal deaerator mainly utilizes the pending water of Steam Heating, and oxygen in water is separated, and discharges, reach deoxygenation object with this through exhaust outlet.Visible, whether thermal deaerator smoothly deoxygenation key can be that whether heating steam amount is sufficient.Therefore this oxygen-eliminating device needs at substantial exogenous steam, and power consumption is large, and cost is high.
Summary of the invention
For the problems referred to above, the invention provides a kind of self-heating oxygen-eliminating device with heat exchanger.
Technical scheme of the present invention is: a kind of self-heating oxygen-eliminating device with heat exchanger, comprises thermal deaerator, increase heat exchanger simultaneously; Wherein thermal deaerator comprises exhaust outlet, steam inlet, water supplement port and delivery port; Heat exchanger is shell-and-tube heat exchanger, comprises cold water inlet, cooling water outlet, hot water inlet and hot water outlet; Water supplement port is connected with cooling water outlet, and delivery port is connected with hot water inlet; In addition, this exchanger heat water out can connect the heating systems such as boiler.
When the self-heating oxygen-eliminating device of described band heat exchanger runs, preheating treat that deaerated water enters thermal deaerator through thermal deaerator water supplement port, with the high-temperature steam Hybrid Heating entering oxygen-eliminating device through steam inlet, be warming up to more than 100 DEG C deoxygenations; Produce high temperature deaerated water enter heat exchanger through delivery port, carry out heat exchange with pending water, preheating treat that deaerated water enters oxygen-eliminating device deoxygenation again.
Compared with existing oxygen-eliminating device, the self-heating oxygen-eliminating device of band heat exchanger of the present invention, oxygen-eliminating device is entered after deaerated water preheating, reduce heating steam consumption, improve oxygen-eliminating device oxygen removal efficiency, high temperature deaerated water directly supplies steam generator system use after heat exchanger cooling simultaneously, reduces exhaust gas temperature, improves steam generator system efficiency.

Fig. 1 is the structural representation of the self-heating oxygen-eliminating device of described band heat exchanger.
Wherein, 1: thermal deaerator; 11: exhaust outlet; 12: steam inlet; 13: water supplement port; 14: delivery port; 2: heat exchanger; 21: cold water inlet; 22: cooling water outlet; 23: hot water inlet; 24: hot water outlet.
Detailed description of the invention
For being illustrated more clearly in the present invention, be illustrated especially exemplified by an example, but the right of application claims more than that.
A kind of self-heating oxygen-eliminating device with heat exchanger as shown in Figure 1, it comprises thermal deaerator (1), also comprises heat exchanger (2); Wherein the water supplement port (13) of thermal deaerator (1) is connected with the cooling water outlet (22) of heat exchanger (2), preheating treat that deaerated water enters thermal deaerator (1) through this; Delivery port (14) is connected with hot water inlet (23), and high temperature deaerated water flows out through this; Treat that deaerated water enters heat exchanger (2) through cold water inlet (21) and carries out heat exchange with high temperature deaerated water; In addition, this exchanger heat water out (24) connects boiler, and deaerated water directly supplies steam generator system.
In the self-heating oxygen-eliminating device running of this band heat exchanger, 20 DEG C of pending water pump into heat exchanger (2), carry out heat exchange with high temperature deaerated water and be warming up to 95 DEG C, thermal deaerator (1) is entered further through thermal deaerator water supplement port (13), high-temperature steam Hybrid Heating with entering thermal deaerator (1) through steam inlet (12), is warming up to 105 DEG C and gets final product deoxygenation; Meanwhile, 105 DEG C of high temperature deaerated water of generation then enter heat exchanger (2) by delivery port (14), further with treat that deaerated water carries out heat exchange and is cooled to 60 DEG C, directly supply steam generator system use.
The self-heating oxygen-eliminating device of this band heat exchanger shown in Fig. 1, remarkable reduction equipment, to the demand of outside high-temperature steam, improves steam generator system efficiency simultaneously.
