Title:
SYSTEM FOR AUTOMATIC GAS EXTRACTION AND DISCHARGE
Document Type and Number:
WIPO Patent Application WO/2019/019514
Kind Code:
A1
Abstract:
A system for automatic gas extraction and discharge, comprising: a gas-discharge chamber (1), a gas-extraction chamber (2) and a gas-liquid separation chamber (3); the gas-discharge chamber (1) is connected by means of a solenoid valve (11, 12) pipeline to a low temperature generator and/or a condenser; the gas-extraction chamber (2) is connected to an absorber by means of a pipeline; the gas-liquid separation chamber (3) is connected to the gas-discharge chamber (1) and the gas-extraction chamber (2) respectively by means of pipelines; the gas-liquid separation chamber (3) is internally provided with a liquid level detecting element (4). The system for automatic gas extraction and discharge enables a non-condensable gas to automatically flow into the gas-discharge chamber (1) by means of a pipeline without needing to add a siphon or an ejector device for forced introduction, and may extract the non-condensable gas inside of a water chamber of the low temperature generator as well as inside of the condenser during non-stop operation without requiring a vacuum pump, thereby greatly reducing costs and simplifying operation.
