Air current flow distribution on-line adjusting device and method of electrostatic-fabric integrated dust collector

Abstract

The invention relates to an air current flow distribution on-line adjusting device and a method of an electrostatic-fabric integrated dust collector and relates to an electrostatic-fabric integrated dust collector. The adjusting device comprises an inlet loudspeaker, an air current distribution board, an electric field area, an ash hopper, bag areas, net air branch chambers, lift valves, outlet smoke boxes, flow adjusting boards and an ash hopper guide plate; and the air current distribution board is arranged between an outlet of the inlet loudspeaker and the electric field area, the ash hopper is arranged at the bottom of the electric field area, the ash hopper guide plate is arranged in the ash hopper, the flow adjusting boards are arranged between the net air branch chambers and the electric field area, the bag areas are arranged in the net air branch chambers, and the lift valves are arranged above the net air branch chambers and arranged in the outlet smoke boxes. The on-line adjusting method includes performing on-line monitoring of flow of the net air branch chambers in the operating process of the electrostatic-fabric integrated dust collector; calculating relative flow deviation of the net air branch chambers; judging whether the relative flow deviation of the net air branch chambers meets requirements; and performing on-line adjusting of valve opening of the lift valve according to feedback signals of an on-line flow monitor, and balancing the flow of the net air branch chambers until the relative flow deviation of the net air branch chambers meets requirements.

Description

technical field [0001] The invention relates to an electric bag composite dust collector, in particular to an online adjustment device for air flow distribution of the electric bag composite dust collector and an online adjustment method for air flow distribution of the electric bag composite dust collector. Background technique [0002] With the country's increasingly stringent environmental protection requirements, the application of electric bag composite dust removal technology in the field of smoke and dust control has developed rapidly. This technology organically combines the advantages of electrostatic precipitator and bag dust removal technology. An electric field area is set in the front stage to collect most of the dust, giving full play to the high efficiency of the front stage electric field dust collection; a small amount of fine dust is collected in the rear stage filter bag area. Give full play to the characteristics of high filter efficiency of bag dust remo...
