Separation Performance of Luwa TLT Eliminator

Abstract

Luwa TLT eliminator is a kind of the eliminators constructed by zigzag bended thin-plates. A bending angle of this eliminator is 60°, a bending number of 3, and a thickness of plate made of CPVC is about 2 mm. The each bending corner of this is round more or less, and the each bending plate has a few zigzag parts. Luwa TLT eliminators used here have two different dimensionless pitches, one is 0.64 (pitch of 24 mm) which the other is 1.07 (pitch of 40 mm) .
In this paper, separation of water droplets from air including water droplets by Luwa TLT eliminators is investigated through experiments, and obtained separation performances are considered as compared with the results predicted by theoretical analysis which has been presented by one of the authors of this paper. And furthermore resistance coefficients of these eliminators are also investigated.
The test section is the vessel made of 10 mm thick transparent acrylic sheet (same material used in the existing horizontal duct), and Luwa TLT eliminator is incased in it. Experiments have been made varying from 2.0 to 10.0 m/s in mean air velocity and varying from 0.085 to 0.95 mg/ (mm²·min.) in mass flow rates of water droplets at inlet of the test section, respectively. The water droplets have been obtained in various sizes from about 5 to 170μm.
