Problems solved by technology

[0004] However, the use of cleaning water to backwash the ceramic plate requires high water quality for the backwash water, and the impurity content of the backwash water is required to be less than 50ppm, otherwise it will easily cause the blockage of the ceramic plate; Friction and the filter in the pipeline are affected by pollution and blockage, and the pressure loss is large, resulting in unstable backwash water pressure and water volume that finally enters the inner cavity of the ceramic plate, the cleani

Embodiment Construction

[0011] Such as figure 2 As shown, the water backwashing device of the cleaning system of the ceramic filter consists of water pressure regulating hand valves 4 and 6, a filter 5, a pneumatic ball valve 7, a pressure gauge 3, and stainless steel pipe fittings connecting the above components in series to the distribution valve 2 Composed, the air compressor 10 for the air source of the present invention is connected to the pipeline of the water backwashing device through the pneumatic ball valve 9, the air pressure regulating hand valve 8, the water pressure regulating hand valve 6 and the filter 5.

[0012] When the ceramic filter is running normally, close the pneumatic ball valve 7 for cleaning water control, open the air compressor 10 and the pneumatic ball valve 9 for air source control, and adjust the air pressure adjustment hand valve 8 by observing the pressure gauge 3 to obtain the best performance. The pressure and gas volume of the gas used to clean and dredge the ce...

Abstract

The invention discloses an on-line gas cleaning method for a ceramic filter. A medium for on-line cleaning is a compressed gas. The on-line gas cleaning system for the ceramic filter adopts the compressed gas as the cleaning medium, has no impurities in the cleaning process, has small resistance in the pipeline, high speed and small pressure oscillation, and has obvious cleaning effect on the ceramic plate so that the attenuation of the ceramic plate can be slower. The working efficiency of the ceramic filter can be improved by 20 to 30 percent. And everyday a mass of cleaning water can be saved.

Description

technical field [0001] The invention relates to an online cleaning method of a ceramic filter. Background technique [0002] Ceramic filter is a new type of solid-liquid separation equipment integrating electromechanical, microporous ceramics, automatic control, ultrasonic cleaning and other high-tech. It is widely used in mineral processing, chemical industry, coal, metallurgy, sewage treatment and other industries. [0003] When the ceramic filter works, microporous ceramics are used as the filter medium, such as figure 1 As shown, after passing through slurry suction zone I, vacuum drying zone II, and unloading zone III, the ceramic plate enters backwash zone IV, which is the online gas cleaning zone. The pipeline, through the pressure adjustment, enters the inner cavity of the ceramic plate from the distribution valve, cleans the micropores of the ceramic plate from the inside out, and at the same time washes down the residual minerals remaining on the surface of the ce...
