Abstract
The utility model discloses high-oxygen hydrogen-rich tail gas purification equipment for sodium chlorate, which comprises a tail gas pipeline and a Roots blower connected with the tail gas pipeline, the outlet end of the Roots blower is connected with a dechlorinator, and the outlet end of the dechlorinator is sequentially connected with a first deoxygenator and a second deoxygenator. The first deaerator and the second deaerator are respectively connected with a first blow-cooling pipeline and a second blow-cooling pipeline, the outlet end of the second deaerator is sequentially connected with a first cooler and a dryer, the dryer is connected with a PSA (Pressure Swing Adsorption) system, and the PSA system is connected with a discharging pipeline. According to the sodium chlorate tail gas purification device, oxygen with high content in sodium chlorate tail gas can be subjected to multi-stage purification, the purity of hydrogen after the tail gas is purified is improved, the temperature in the deoxidation process of the first deoxidizer and the temperature in the deoxidation process of the second deoxidizer can be reduced respectively, the risk caused by heat generated in the deoxidation process to the deoxidation process is reduced, and the tail gas purification safety is guaranteed.
