[0048] figure 1 It is a flow chart of the method for setting the interval time between adding oxygen-scavenging agents to boilers provided in an embodiment of the present invention.

[0049] Such as figure 1 As shown, the method for setting the interval time for adding oxygen-scavenging agents to the boiler includes steps S110-S150:

[0050] S110. Calculate the first unit consumption of the boiler based on the current medicament dosing interval of the boiler.

[0051]In this embodiment, the method for setting the interval time for adding oxygen-scavenging agent to the boiler is used for the industrial boiler operation mode in which thermal deoxidation is mainly used and chemical deoxygenation is supplemented. Thermal deaeration refers to the use of steam to heat the boiler feed water to the saturation temperature under the pressure of the atmospheric thermal deaerator. At this time, the steam pressure on the water surface is close to the full pressure of the water surface, a...

[0081] Based on the same inventive concept as that of the method in the first embodiment, correspondingly, this embodiment also provides a device for setting the time interval for adding oxygen-scavenging agents to the boiler.

[0082] Figure 4 It is a flow chart of the device for setting the interval time of boiler oxygen-scavenging agent injection provided by the present invention.

[0083] Such as Figure 4 As shown, the shown device 4 includes: 41 first unit consumption calculation module, 42 real-time dissolved oxygen content acquisition module, 43 time adjustment module, 44 second unit consumption calculation module and 45 optimal time determination module.

[0084] Wherein, the first unit consumption calculation module is configured to calculate the first unit consumption of the boiler based on the current medicament dosing interval of the boiler, and the unit consumption is equal to the ratio of the total operating cost to the effective steam production;

[0110] The above method and device can be applied to terminal devices such as desktop computers, notebooks, palmtop computers and cloud servers.

[0111] Figure 5 It is a schematic diagram of a terminal device that can apply the above method and device provided in an embodiment of the present invention. As shown in the figure, the device 5 includes a memory 51, a processor 50, and is stored in the memory 51 and can be stored in the memory 51. The computer program 52 running on the processor 50, when the processor 50 executes the computer program 52, implements the steps of the method for setting the interval time of adding oxygen-scavenging agent to the boiler. E.g Figure 4 The functions of modules 41 to 45 are shown.

[0112] The device 5 may be a computing device such as a cloud server. The terminal device may include, but not limited to, a processor 50 and the memory 51 . Those skilled in the art can understand that, Figure 5 It is only an example of the device 5 an...

Abstract

The present invention is applicable to the field of energy technology, and provides a method and device for setting the interval time of boiler oxygen-scavenging chemical dosage, wherein, the method includes: calculating the first unit consumption of the boiler based on the current boiler dosage interval time; obtaining The real-time dissolved oxygen content obtained by detecting the boiler feed water; based on the real-time dissolved oxygen content, adjust the boiler’s current medicament delivery interval; calculate the second unit consumption of the boiler under the adjusted medicament delivery interval; based on For the first unit consumption and the second unit consumption, it is determined that the medicament dosing interval corresponding to the minimum unit consumption is the optimal medicament dosing interval. The invention provides scientific guidance for the operation of specific industrial boilers by setting a reasonable time interval for medicament delivery, improves the deaeration efficiency, reduces the steam consumption and exhaust loss of the deaerator, saves the cost of the deaerator, and thus achieves equipment safety. The effect of operation and energy saving and consumption reduction.

Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to a method and a device for setting the time interval for adding oxygen-removing agents to boilers. Background technique [0002] In the boiler feed water treatment process, oxygen removal is a very critical link. Oxygen is the main corrosive substance in the boiler water supply system. Oxygen in the water supply system should be removed quickly, otherwise it will corrode the boiler water supply system and components, and the corrosive substance iron oxide will enter the boiler, deposit or adhere to the boiler tube wall and On the heating surface, iron scale that is insoluble and poor in heat transfer is formed, and the corroded iron scale will cause pits on the inner wall of the pipeline, and the resistance coefficient will increase. When the pipeline corrosion is serious, even pipeline explosion accidents may occur. The state stipulates that steam boilers with an ev...
