Foul gas exhaust system for ammonia water power generation system

Abstract

The invention discloses a foul gas exhaust system for an ammonia water power generation system. The foul gas exhaust system comprises a steam condenser, a hot well, an ammonia water working medium liquid storage tank and an absorption tank; the hot well is arranged below the steam condenser and comprises a gas phase area at the upper part and a liquid phase area at the lower part; the liquid phase area of the hot well is connected with the ammonia water working medium liquid storage tank by a liquid drainage pipeline; the gas phase area of the hot well is communicated with an absorption medium of the absorption tank by an exhaust pipeline; an exhaust valve is arranged at the top of the absorption tank; the bottom of the absorption tank is connected with the ammonia water working medium liquid storage tank by a liquid conveying pipeline. An ammonia water working medium in foul gas can be thoroughly separated, and the safety and stability of the system are ensured, foul gas can be safely thoroughly exhausted and the pollution to the environment is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of ammonia water power generation, and in particular relates to a non-condensable gas discharge system used in an ammonia water power generation system. [0002] Background technique [0003] With the in-depth utilization of medium and low temperature waste heat in production enterprises, organic working fluid power generation will be gradually promoted, and power generation with ammonia water as a working medium, which is suitable for medium and low temperature heat sources, will also be widely used. During the operation of the ammonia water generator set, some ammonia water will decompose, and other factors will lead to the existence of non-condensable gas in the system. These non-condensable gases contain a large amount of ammonia water. If they are directly discharged into the atmosphere, it will inevitably cause The loss of ammonia working medium will affect the stability and efficiency of system op...

Problems solved by technology

During the operation of the ammonia water generator set, some ammonia water will decompose and other factors will lead to the existence of non-condensable gases in the system. These non-condensable gases contain a large amount of ammonia water. If they are directly discharged into the atmosphere, it will inevitably cause The loss of ammonia working medium will affect the stability and efficiency of system operation, and will also cause environmental pollution. Therefore, it is necessary to take effective measures to recover ammonia working medium in non-condensable gas to ensure the normal operation of the system
