EXPERIMENTAL STUDY ON A LABORATORY-SCALE TRANSVERSE-PLATE ELECTROSTATIC PRECIPITATOR

摘要

Currently, various techniques and methods are used to enhance the collecting efficiency of electrostatic precipita-tors. In this paper, experiments of simulating flue gas purification are carried out using a laboratory-scale transverse-plate electrostatic precipitator (TPESP) system, and the dust collecting mechanism of TPESP is also discussed. The influence factors of dust collecting efficiency are examined, such as initial dust density, working voltage, effective dust collecting area and gas velocity. From the experimental results, the dust collecting efficiency of a single electric field in TPESP is 3 times more than in a traditional ESP, and TP system decreases traditional ESP volume effectively. Miniaturization of TPESP is realized, and its one-off investment is greatly reduced.
