AI Technical Summary
Existing organic gas recovery systems have poor recovery rates and are not adjustable in operation. Multi-stage condensation processes are costly and require large equipment footprints, making them unsuitable for small businesses.
A combined system consisting of an induced draft fan, a buffer tank, a membrane module, a vacuum pump, a condenser, and a collection tank is adopted. Through the interconnected design of the buffer tank and the collection tank, combined with a cooler and a flow meter, the efficient recovery and recycling of organic gases can be achieved.
It improves the recovery rate of organic gases, reduces pollutant emissions, saves energy and reduces consumption, avoids additional equipment and power requirements, and is suitable for small businesses.
