Core Functions Of Vacuum Degasifier In Power Industry

• Dissolved Oxygen Removal: Dissolved oxygen in boiler feed water and circulating water of power plants will cause severe corrosion of metal equipment such as boilers, pipelines, and heat exchangers, reducing equipment service life and even leading to safety accidents. The vacuum degasifier uses vacuum pressure to reduce the partial pressure of oxygen in the liquid, enabling efficient separation of dissolved oxygen. Tangshan Dachuan’s vacuum degasser can reduce the dissolved oxygen content in water to below 0.01 mg/L, meeting the strict water quality requirements of the power industry.

• Carbon Dioxide Removal: Dissolved carbon dioxide in water will lower the pH value of the water, increasing the corrosiveness of the water and causing acid corrosion to equipment. The vacuum degasifier can synchronously remove dissolved carbon dioxide while removing oxygen, adjusting the water quality to a neutral or weakly alkaline state. This effectively inhibits acid corrosion and protects the integrity of power plant equipment. The company’s mud degasser also has excellent carbon dioxide removal performance, suitable for gas removal in drilling mud during power plant foundation construction.

• Stabilization Of Working Medium Performance: By removing dissolved gases, the vacuum degasifier stabilizes the physical and chemical properties of the working medium (water, mud, etc.), avoiding gas-induced problems such as cavitation, foam generation, and heat transfer efficiency reduction. Stable working medium performance ensures the efficient operation of power generation equipment, improves power generation efficiency, and reduces energy consumption. Tangshan Dachuan’s vacuum degasifier is designed with precise vacuum control systems to ensure stable gas removal effects.

• Auxiliary Mud Treatment For Power Plant Construction: During the construction of power plant foundations, tunnels, and other projects, drilling mud is often used for wellbore stabilization. The mud degasser (a type of vacuum degasser for mud systems) can quickly remove gas from drilling mud, avoiding mud foaming and reducing the risk of wellbore collapse. This ensures the smooth progress of power plant construction projects. Tangshan Dachuan’s mud degasser can be perfectly matched with other mud treatment equipment such as shale shakers and mud cleaners, forming an integrated construction mud treatment system.

Correct Use And Maintenance Of Vacuum Degasifier In Power Industry

To ensure that the vacuum degasifier maintains high efficiency and stability during long-term use in the power industry, correct use and regular maintenance are essential. Tangshan Dachuan Machinery Co.,ltd. summarizes the following key points based on years of practical experience:

• Strictly Control Inlet Medium Parameters: Before using the vacuum degasifier, ensure that the temperature, pressure, and solid content of the inlet medium (water, mud) meet the equipment’s operating requirements. Excessively high solid content will cause clogging of the equipment’s internal components, while unstable pressure will affect the vacuum degree and gas removal effect. The company’s mud degasser is equipped with a pre-filter device to reduce the impact of solid particles on the equipment.

• Pre-Operation Inspection: Before starting the vacuum degasifier, check the integrity of the vacuum chamber, the tightness of the pipeline connection, the oil level of the vacuum pump, and the operation status of the electrical control system. Ensure all components are in normal condition before starting to avoid equipment failure affecting the operation of the power system.

• Regular Cleaning And Maintenance: After long-term use, timely clean the internal components of the vacuum degasifier (such as the gas-liquid separator, nozzle) to remove scale and dirt. Regularly inspect and replace worn parts (such as seals, bearings) to ensure the equipment maintains good vacuum performance. Tangshan Dachuan provides detailed maintenance manuals and original spare parts to help users carry out maintenance work efficiently.

• Reasonable Matching With Supporting Equipment: Ensure that the vacuum degasifier is reasonably matched with other supporting equipment (such as water pumps, filters, and monitoring instruments) in the system. Mismatched equipment will lead to low overall efficiency of the gas removal system. Tangshan Dachuan’s professional team will provide customized system matching schemes according to the user’s specific power industry application scenarios.
