Abstract
The invention discloses an online sand blasting descaling method for an electric dust remover, which is implemented according to the following steps: 1. an open dry sand blasting process is adopted, and the inflatable suit is worn to manually remove scale in an electric field; 2. according to on-the-spot polar plate parameter of polar line, will avoid spraying the too big polar plate of damaging polar line of intensity, warp or fracture, injection angle: the polar plate adopts a plane more than 120 degrees, and the polar line spraying angle adopts non-prickle surface spraying, so that the prickle caused by direct spraying is avoided; 3. selecting a sand blasting material: garnet or copper ore sand or diamond sand or quartz sand or river sand is adopted; the granularity is 0.5mm-1 mm. The method can quickly and conveniently remove dust and dirt on the electric dust remover and ensure the normal production.
Description
Technical Field
The invention relates to an online sand blasting descaling method for an electric dust collector.
Background
Since the 150t electric field dust collector is on line in 2013, the dirt accumulated on polar plates of the polar plates is thick, the electric charges cannot be released, the electric field dust collection efficiency is greatly reduced, and the increase rate of the data of the externally-discharged peak can reach 2.5 times in about 5 years. Compared with domestic use units and manufacturing units in the same industry, no effective method for daily scale removal of polar plates of the electrostatic precipitator exists. At present, the large top cover of the electric dust collector is disassembled for a certain period of time, and the polar line is replaced; the construction period is long and the investment cost is high; in addition, in order to avoid conflict with production, construction is generally carried out in winter, and the winter construction affects the quality of sealing operation. In domestic large steel mills such as Bao steel, saddle steel, Wu steel, Shao steel and sand steel, there is no regular maintenance method for on-line descaling.
Disclosure of Invention
The invention aims to provide an online sand blasting descaling method for an electric dust remover, which can quickly and conveniently remove dust and dirt on the electric dust remover and ensure the normal production.
The technical scheme for realizing the invention is that the online sand blasting descaling method for the electric dust remover is implemented according to the following steps: 1. an open dry sand blasting process is adopted, and the inflatable suit is worn to manually remove scale in an electric field; 2. according to on-the-spot polar plate parameter of polar line, will avoid spraying the too big polar plate of damaging polar line of intensity, warp or fracture, injection angle: the polar plate adopts a plane more than 120 degrees, and the polar line spraying angle adopts non-prickle surface spraying, so that the prickle caused by direct spraying is avoided; 3. selecting a sand blasting material: garnet or copper ore sand or diamond sand or quartz sand or river sand is adopted; the granularity is 0.5mm-1 mm.
The method for removing the dust and dirt on the electric dust remover is simple and easy to implement, has good cleaning effect which can reach SA2 level, can effectively improve the working efficiency of the electric dust remover, greatly reduces the production cost of enterprises, and ensures that the production is normally and orderly carried out.
