Intelligent brushing, sweeping and rapping device for high voltage electrostatic precipitator tail electric field

Abstract

The invention relates to an intelligent brushing, sweeping and rapping device for a high voltage electrostatic precipitator tail electric field. Wire brushes are arranged on two sides of an anode plate and are fixed on a square steel, two sides of the square steel are respectively connected with a transmission mechanism through steel wire ropes, the transmission mechanism is connected with a connecting rod which is connected with an electromagnetic clutch through a transmission chain, and the electromagnetic clutch is connected with a reducer which is connected with a motor. A dust secondary processing device is arranged between a dust cleaning chamber and an airflow outlet bin by supports. According to the intelligent brushing, sweeping and rapping device for the high voltage electrostatic precipitator tail electric field, rapping flying dusts can be reduced, compared with a traditional electric precipitator, a dust removal of a polar plate depends on the rapping, and a dust layer is peeled off from a polar plate surface to drop into a dust hopper, thereby the rapping flying dusts can be effectively avoided, and a dust emission concentration of an electric precipitator outlet device can be remarkably reduced.

Description

technical field [0001] The invention relates to a brushing device, in particular to a device for cleaning dust, in particular to an electric field intelligent brushing and vibrating device at the tail of a high-voltage electrostatic precipitator. Background technique [0002] my country has introduced increasingly stringent regulations on dust emissions from power plants and other industrial processes, creating a need for more efficient dust removal equipment. Secondly, due to the continuous rise of coal prices and the specific implementation of national energy-saving and consumption-reducing measures, a large number of discarded low-calorific value coals have been used in large quantities, causing the dust load to exceed the design capacity of the original dust removal equipment, resulting in excessive emissions. This requires new High-efficiency dust removal technology to transform the original dust collector. [0003] Electrostatic precipitator is currently the main equi...

Problems solved by technology

But there are two inherent problems of electrostatic precipitator: secondary dust and back corona

If these phenomena occur in the front-stage electric field, other electric fields will have a chance to collect again, but if they occur in the last-stage electric field, the dust can only escape with the airflow, resulting in an increase in outlet emissions
