Abstract
Abstract
Dust prevention and control in the tobacco industry has always been the top priority, because the discharge of tobacco dust can cause workers’ pneumoconiosis, explosions, fires and other safety hazards. This article summarizes the advantages and disadvantages of the traditional three kinds of dust collectors. The author designed a tobacco dust in-situ purification system based on the principle of throttling gas-liquid exchange. The experiment selects the three factors of the initial liquid level, inlet wind speed, and feed concentration in the system, and conducts orthogonal experiments to obtain the purification efficiency of the system under different experimental conditions. The results show that the maximum purification efficiency of the laboratory can reach 99.27%. The purification efficiency is mainly referred to between 97%∼99%. Through the actual application of the site, it can be known that under the long-term operation of the system, the emission concentration at different links and distances is still less than 2 mg/m3, which meets the national dust emission standard.
