Description

Technical Field

[0001] The invention relates to the technical field of open heat exchangers, in particular to a condenser deoxidation open heater. Background Art

[0002] As we all know, thermal power generators require regular demineralized water replenishment during operation to ensure proper operation. Early thermal power plants directly injected large amounts of demineralized water into the condenser to replenish the boilers. However, due to the low feed water temperature, additional heat was required to heat it, resulting in heat loss. Direct demineralized water replenishment into the condenser also resulted in high oxygen content, which can lead to equipment corrosion and severely impact the reliability of the condensate and feed water systems. Existing open-type heaters often utilize fixed, porous plate structures, which limit the contact area between steam and water and result in low deoxygenation efficiency. Furthermore, these heaters lack dynamic adjustment capabilities, making it impossible to optimize operating parameters based on operating conditions such as fluctuating steam flow and varying water quality. Traditional equipment is difficult to disassemble, resulting in lengthy downtime for maintenance and impacting production efficiency. Therefore, a solution to this technical issue is necessary. Summary of the Invention

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a condenser deoxidation open heater, which has the following beneficial effects:

[0014] The condenser deaerator open heater directly impacts the condensate in the condenser hot well through the injection holes opened on the bottom plate, thereby enhancing the bottom heat exchange. Multiple jets are formed upward through the injection holes of the four vertebral plates, which expands the contact area between steam and water and improves the dissolved oxygen efficiency. The modular design of the docking block, top cover and threaded column enables the rapid locking and disassembly of the four vertebral plates, reducing maintenance time. The oxygen content sensor is embedded in the inner wall of the steam inlet pipe and directly contacts the steam flow, reducing measurement delay and improving accuracy.

Then, the top cover 7 is pressed against the top of the center position of the cone head composed of the multiple vertebral plates 2. At this time, the personnel hold the positioning column 8, and thread the threaded column 9 on the top cover 7 with the threaded hole. Then, the positioning column 8 is loosened and the threaded column 9 is continued to be rotated so that the threaded column 9 is rotated into the threaded hole.
