Description

Technical Field

[0001] This utility model belongs to the field of waste heat power generation technology, and specifically relates to a steam waste heat and waste pressure power generation device utilizing a high-pressure deaerator. Background Technology

[0002] High-pressure deaerators are critical equipment used to remove dissolved gases (mainly oxygen and carbon dioxide) from boiler feedwater or industrial water to prevent corrosion of pipelines and equipment under high temperature and pressure conditions. They are widely used in industrial fields requiring large amounts of steam and hot water, such as thermal power plants, chemical plants, and paper mills. High-pressure deaerators generate high-temperature gases during operation. To utilize these gases, a high-temperature gas conveying mechanism is added externally to the deaerator for power generation. The high-temperature gas generates steam through heat exchange, and the steam is then compressed into high-temperature, high-pressure gas and introduced into a steam turbine to complete auxiliary power generation. However, intermittent maintenance and cleaning are required during steam generation and use. Since most of the relevant components are integrated with the high-pressure deaerator, this can lead to prolonged downtime. During these periods, the waste heat generated by the high-pressure deaerator cannot be utilized, resulting in waste and affecting actual power generation.

[0003] In summary, the intermittent shutdown of the high-pressure deaerator waste heat and pressure power generation device presents some problems during operation. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
