AI Technical Summary
Existing sulfur tetrafluoride gas purification equipment is unable to effectively remove a variety of impurities, resulting in limited purification effects that fail to reach the ideal level.
The system employs a two-stage dust collector, which contains a first adsorption component and a second adsorption component to remove acidic gases and low-valent sulfur and fluoride compounds, respectively. Through chemical and physical adsorption principles, the airflow proceeds from bottom to top, purifying layer by layer. Combined with the design of the diversion plate and drain valve, it ensures the layer-by-layer adsorption of impurities and the stability of the equipment.
It significantly improves the purification effect of sulfur tetrafluoride gas, ensures that the gas quality meets the standards, avoids the problem of insufficient treatment efficiency of a single adsorbent, and maintains the stability and cleanliness of the equipment.
