一种页岩气采气用无硅消泡剂投加控量装置
By monitoring the amount of foam with a microwave sensor and combining it with a conical shell and spiral guide vane structure, the problem of controlling the amount of defoamer in shale gas production without silicon digester was solved. This enabled uniform mixing of the defoamer and produced water, improved the defoaming effect, and ensured efficient gas-liquid separation.

AI Technical Summary
Existing silicone-free defoamers are not added in precise amounts during shale gas extraction, resulting in poor defoaming effects and uneven mixing in the pipeline, which affects gas-liquid separation.
A microwave sensor is used to monitor the amount of foam, and a metering pump is used to add defoamer in controlled quantities. A conical shell and spiral guide vane structure is used to promote the mixing of defoamer and produced water. Combined with repeated depressurization and pressurization processes, efficient mixing is achieved.
This ensures thorough mixing of the defoamer with the produced water, improves the defoaming effect, and guarantees efficient gas-liquid separation.
