Ash removal device

Technical Field

The utility model relates to the technical field of ash cleaning equipment, in particular to an ash cleaning device.

Background

Most of flue gas dust removal processes of thermal generator sets adopt electrostatic dust collectors, dust in flue gas moves towards anode plates under the action of electrostatic force and is attached to anode plates, and dust on the anode plates is generally removed through vibration and the like.

However, as the moisture and ammonia in the flue gas escape increases, dust is easy to harden on polar plate wires to form scale, so that the dust cannot be removed by vibration and other modes, and shutdown cleaning is required. During the shutdown cleaning period, the distance between the polar plates is shorter, about 0.3-0.4 m, the height of the polar plates is higher, about 15m is not supported between the polar plates, the manual force cannot enter the polar plates to carry out ash cleaning operation, the ash accumulation in partial regions of the polar plates is easy to cause the ash cleaning failure, the maintenance effect is poor, the dust removal effect of the dust remover is further reduced, and the standard discharge of the smoke pollutants of the unit is influenced.

In summary, how to improve the ash removal effect of the electrode plate during the maintenance is a problem to be solved by those skilled in the art.
