Air flow distribution plate at inlet of electrostatic dust collector

Abstract

The invention provides an air flow distribution plate at an inlet of an electrostatic dust collector, relating to the electrostatic dust collector used in a dry method dust collection technology of a rotation furnace gas. The air flow distribution plate is provided with a through hole and arranged in a gradually expended horn mouth at the inlet of electrostatic dust collector. The air flow distribution plate is characterized in that the air flow distribution plate is of a dish shape and is spliced by at least regions; and further, the aperture ratio of the air flow distribution plate is gradually increased from the centre to the outside. The air flow distribution plate has the beneficial effects that through arranging the dish-shaped air flow distribution plate, the flow velocity and flowquantity of the air at the central region are reduced by the air flow distribution plate at the reducing nipple position of the inlet of the electrostatic dust collector, and the flow velocity and flow quantity of the air at the fringe region are increased, thereby effectively inhibiting vortex, so that the air flow entering the electrostatic dust collector is of a plunger shape and evenly distributed, thereby reducing the explosion time of the electrostatic dust collector and improving the dust-collecting effect; and the aperture ratio of the air flow distribution plate is increased from thecentre to the outside, thereby further improving flow equalizing effect.

Description

technical field [0001] The invention relates to an electrostatic precipitator used in a converter gas dry dedusting process, in particular to an inlet airflow distribution plate of the electrostatic precipitator. Background technique [0002] Converter gas dry dedusting technology has been widely used due to its advantages in energy saving, water saving and environmental protection. Among them, the electrostatic precipitator is the core of the whole dedusting system. Due to the process characteristics of converter steelmaking, gas and air will pass through the electrostatic precipitator periodically. In the alternating phase of gas and air, an explosion will occur when the mixture is within the explosion limit range. How to reduce the occurrence and scale of gas explosion in the electrostatic precipitator is the key to the safe and stable operation of the converter gas dry dedusting system. [0003] An effective way to reduce the probability of explosion venting is to cont...
