Development of a new type of ammonia eliminator for swirl purifiers and study of its ammonia-eliminating mechanism

Abstract

In this paper, we presented the construction of a test platform for ammonia elimination in swirl purifiers and the development of a new type of compound high-efficiency ammonia eliminator. A combined experimental and simulation approach has been shown to provide insights into the simultaneous purification of underground dust and ammonia. Firstly, the elimination effects of six reagent A-F in a short period of time were compared to establish performance evaluation system and reagent A and B exhibited the most effective performance. Secondly, reagents A and B were prepared in a ratio of 2:1, 3:1, and 3:2 to obtain reagents a, b, and c for comparative analysis. The test results demonstrated that reagents a, b, and c were mixed within 10, 5, and 10 min, respectively; the efficiency of ammonia elimination was 80 %, 83.3 %, and 76.7 %, respectively; the steady-state duration was 410, 500, and 320 min, respectively; and the continuous operation time was 830, 970, and 710 min, respectively, demonstrated that reagent b is the most effective. In addition, reagent b improved the odor of the discharged gas. Finally, molecular dynamics simulations were used to discuss the mechanism of simultaneous purification of ammonia and dust by composite reagent was discussed. The new type of ammonia eliminator was ultimately shown to employ in conjunction with swirl purifiers for efficient ammonia elimination.
