Description

Technical Field

[0001] The invention relates to the technical field of soda pipelines, and in particular to a soda pipeline blocking protection device. Background Art

[0002] In a power plant, the boiler steam pipeline is an important part of the boiler steam-water system. It undertakes key tasks such as water circulation, steam generation and transportation. The boiler steam is mainly composed of water and steam. Water is heated to boiling in the boiler and continues to absorb heat and convert into steam. In this process, the water will go through preheating, evaporation, superheating and other stages, and finally form superheated steam with a certain pressure and temperature. Therefore, the safety of the steam pipeline is particularly important.

[0003] Due to the complex and large structure of the water-steam system pipeline of the ultra-supercritical unit, the small number of nitrogen filling lines cannot meet the shutdown corrosion control requirements of the water-steam system, which will increase the time it takes for the entire line to be filled with nitrogen. Once the shutdown corrosion control effect is not ideal, it will cause equipment damage and a decrease in the unit's energy conversion rate.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN117329380B discloses a corrosion protection pipeline structure for the water vapor system of an ultra-supercritical unit. The device connects the water vapor system corrosion protection device in parallel in the water vapor system pipeline, uses the inflation pipe to inflate the inside of the water washing system pipeline, and inflates the inside of the water vapor pipeline where the inflation pipe is located through the inflation and pressurization component on the pressurization unit. The inflation and pressurization component can increase the gas flow rate, thereby anti-corrosion flushing the pipeline while inflating, thereby improving the anti-corrosion effect; However, in actual production operations, under high temperature and high pressure environments, the sampling instrument may be easily damaged due to excessively high water vapor temperature during the water vapor sampling process.
