Ash conveying system transformation method

Abstract

The invention provides an ash conveying system transformation method, and belongs to the technical field of desulfurization, denitrification and dust removal. Comprising the following steps: S1, transforming a fluidization chute: transforming the size of the fluidization chute to be 280mm in height and 230mm in width; s2, fluidization cloth is arranged, the distance between the position of the fluidization cloth and the bottom of the fluidization chute is 92 mm, a fluidization air channel is arranged on the lower portion of the fluidization cloth, and the upper layer of the fluidization cloth is an actual effective ash discharging space; s3, a fluidization chute is installed, wherein the fluidization chute is installed at the installation inclination angle of 6 degrees; and S4, after the desulfurized waste ash falls into the fluidization chute, conveying the desulfurized waste ash into a waste ash silo under the combined action of fluidization air, gravity and suction force of dust collection air of the ash silo. After the desulfurization waste ash modified by the device falls into a new fluidization chute, the condition that a large amount of desulfurization waste ash is accumulated before does not exist, and the desulfurization waste ash can be quickly conveyed into the waste ash silo under the combined action of fluidization air, gravity and dust collection air suction of the ash silo, so that extrusion congestion is avoided, the condition that part of desulfurization ash is accumulated for a long time is reduced, the fluidization effect during ash unloading is improved, and the service life of the desulfurization waste ash is prolonged. In addition, staff maintenance is facilitated, and personal safety is improved.

Description

technical field [0001] This application relates to the technical field of desulfurization, denitrification and dust removal, and specifically relates to a method for transforming an ash conveying system. Background technique [0002] The original ash conveying chute was relatively large (4.5 meters high on the north side and 1.5 meters high on the south side). Due to the relatively small volume of the ash storage, the chute assumed part of the ash storage function in the early stage. After the chute was full of ash, the fluidized cloth at the bottom was affected The waste ash is squeezed and congested, which greatly reduces the fluidization effect during ash unloading, so that part of the desulfurized ash accumulates for a long time. When the chute shell is corroded, aged and cracked, and the waste ash is hardened by moisture after rain, the hardness is relatively high, and the manhole opening of the chute is relatively large. Small, the chute is not equipped with a construc...

[0002] The original ash conveying chute was relatively large (4.5 meters high on the north side and 1.5 meters high on the south side). Due to the relatively small volume of the ash storage, the chute assumed part of the ash storage function in the early stage. After the chute was full of ash, the fluidized cloth at the bottom was affected The waste ash is squeezed and congested, which greatly reduces the fluidization effect during ash unloading, so that part of the desulfurized ash accumulates for a long time. When the chute shell is corroded, aged and cracked, and the waste ash is hardened by moisture after rain, the hardness is relatively high, and the manhole opening of the chute is relatively large. Small, the chute is not equipped with a construction and maintenance platform, and the working height is 15 meters. It is difficult to guarantee the personal safety of the maintenance personnel. After congestion, a large amount of waste ash will be scattered on the ground, seriously affecting the environmental sanitation of the factory area
