Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically, the utility model relates to an electric bag dust collector with over-high dust accumulation overload alarm and emergency ash discharge.

Background Art

[0002] The electric bag dust collector is an essential auxiliary equipment for thermal power plants. Its function is to remove particulate dust in the flue gas discharged from coal-fired or oil-fired boilers, thereby significantly reducing the amount of dust discharged into the atmosphere. This is an important environmental protection equipment for improving environmental pollution and air quality. During the normal operation of the electric bag dust collector, a large amount of dust will adhere to the peripheral side wall of the cloth bag. If the cloth bag is not cleaned in time, the dust removal effect of the electric bag dust collector will be seriously affected.

[0003] An existing easily ash-cleanable electric bag dust collector, with the publication number CN 219540607 U, includes a housing provided with an inlet horn and an outlet horn. Inside the housing, an electric field area and a filter bag area are arranged in series, forming a structure in which flue gas enters the electric field area and the filter bag area in sequence through the inlet horn for dust removal, and finally discharges from the outlet horn. The electric bag dust collector also includes a hopper, which is correspondingly arranged below the electric field area and the filter bag area. An anode plate is arranged in the electric field area, and a vibrating mechanism for vibrating the anode plate is provided. When the ash conveying system of this kind of electric bag dust collector operates normally, no alarm system is set. When a large amount of ash accumulates in the hopper and cannot be cleaned in time, it will lead to a decline in the operation efficiency of the dust collector and pose a safety hazard.
