摘　　要：提出了一种新型仿水滴形管式棒栅脱硫增效装置,并在脱硫试验台上进行了冷态试验,研究了该装置阻力与塔内气体流速、液气比和管栅间隙之间的变化规律。结果表明:仿水滴形管式棒栅脱硫增效装置的阻力随着气体流速和液气比的增大而增大,随着管栅间隙的增大而减小;在气体流速和液气比已知的情况下,可通过选取合适的管栅间隙将仿水滴形管式棒栅脱硫增效装置的阻力控制在500~800 Pa。A novel water-drop-shaped tubular rod-grid desulfurization device was proposed and a cold test was carried out on the desulfurization test bench. The variation laws of the resistance of the device with the gas velocity in the tower, the liquid-gas ratio and the gap between the pipe and grid were studied. Results show that the resistance of the water-drop-shaped tubular rod-grid desulfurization device increases with the increase of the gas velocity and the liquid-gas ratio, and decreases with the increase of the gap between the pipe and grid. Furthermore, under the fixed gas velocity and the liquid-gas ratio, the resistance of the water-drop-shaped tubular rod-grid desulfurization synergistic device can be controlled within the range of 500-800 Pa by selecting the appropriate grid gap.
