Device for prolonging service life of oil-containing filter cloth of continuous casting plate frame

Abstract

The invention relates to a device for prolonging the service life of oil-containing filter cloth of a continuous casting plate frame. The device comprises a continuous casting slurry regulating reservoir, a steelmaking slurry regulating reservoir, a continuous casting plate frame and a steelmaking plate frame, wherein the continuous casting slurry regulating reservoir is connected with the continuous casting plate frame through a continuous casting plate frame feeding main pipe and a continuous casting plate frame filtrate water return pipe; the steelmaking slurry regulating reservoir is connected with the steelmaking plate frame through a steelmaking plate frame feeding main pipe and a steelmaking plate frame filtrate water return main pipe; the continuous casting plate frame feeding main pipe is communicated with the steelmaking plate frame feeding main pipe through a pipeline with a feeding branch pipe valve; and the continuous casting filtrate water return pipe is communicated with the steelmaking filtrate water return pipe through the pipeline with a water return branch pipe valve. Revolving furnace dust removing sludge is treated by using the continuous casting plate frame, has the characteristics of high pH and high basicity, and can be used for cleaning oil sludge attached to the continuous casting plate frame, so that the service performance of the filtering cloth is recovered, and the service life of the filter cloth is prolonged.

Description

technical field [0001] The invention relates to a device for improving the service life of a continuous casting plate and frame oil-containing filter cloth, in particular to a device for removing oil sludge on a plate and frame filter cloth by utilizing high pH and high alkalinity sludge, and belongs to the technical field of industrial water treatment. Background technique [0002] Plate and frame filter press technology is widely used in sludge treatment projects in the iron and steel industry. Due to the difference in water quality between the continuous casting system and the steelmaking system, it is also distinguished in the sludge treatment project, using continuous casting plate frame and steelmaking steel plate respectively The frame is used to treat the sludge of the continuous casting system and the steelmaking system. During the production process of the plate and frame, due to the high oil content in the continuous casting circulating water system, after the con...

AI Technical Summary

Problems solved by technology

During the production process of the plate and frame, due to the high oil content in the continuous casting circulating water system, after the continuous casting oily sludge is treated by the continuous casting plate and frame, a large amount of oil sludge adheres to the filter cloth, causing serious blockage of the filter cloth, resulting in poor water permeability of the filter cloth , the processing capacity is reduced, and at the same time, the continuous casting plate and frame often have material leakage, and it also affects the sludge treatment effect, affects the normal sludge discharge of the continuous casting water treatment equipment, and then affects the water quality

In order to solve the oil sludge problem of the filter cloth, the processing pressure of the plate and frame can only be relieved by frequent replacement of the filter cloth, but this method cannot fundamentally solve the problem, and the cost is relatively high, and the workload of the workers is also heavy
