摘要:为了解决传统滤袋在收集黏附性粉体时发生糊袋、破损造成环境污染和资源浪费等问题,本文中自建滤筒除尘器和塑烧板除尘器实验平台,以除尘器系统阻力、粉尘排放浓度作为评价指标,评估塑烧板除尘器和滤筒除尘器收集黏附性粉体的性能。结果表明:在喷吹压力为0.4 MPa、过滤风速为0.8 m/min条件下,塑烧板除尘器收集高岭土和勃姆石粉体,设备稳定运行时的阻力值分别为155~520、 325~500 Pa,粉尘排放质量浓度为1 mg/m3,滤筒除尘器收集高岭土粉体时,30 min内系统阻力值增大至6 kPa,收集勃姆石粉体,70 min内系统未能达到稳定运行状态,粉尘排放质量浓度最大值为29 mg/m3。由此可见,在收集黏附性粉尘时塑烧板除尘器的性能更优于滤筒除尘器。

Abstract:In order to solve the traditional filter bag in the collection of adhesive powder paste bag, damage caused by environmental pollution and resource waste problem, this paper constructed an experimental platform of cartridge filter and sintered plastic filter, filter resistance, dust emission concentration as evaluation index, evaluation model to burn plate filter and filter cartridge dust collector to collect adhesion performance of powder. The results show that: under the conditions of injection pressure 0.4 MPa and filtration wind speed 0.8 m/min, Kaolin and boehmite powder are collected by the sintered plastic filter dust collector. The resistance values of the equipment are 155~520 Pa and 325~500 Pa respectively in the stable operation, and the dust emission concentration is 1 mg/m3. When the filter cartridge dust remover collects kaolin powder, the system resistance value rises to 6 kPa within 30 min. When the boehmite powder is collected, the system fails to reach a stable operation state within 70 min, and the maximum dust emission concentration is 29 mg/m3. It is concluded that the performance of plastic burning board dust collector is better than that of cartridge dust collector in collecting adhesive dust.
