Embodiment 1

[0026] A filter cloth cleaning agent, its raw materials are calculated by mass percentage: 6% hydrochloric acid, 5% oxalic acid, 10% sodium dodecylsulfonate, and the rest is water. To clean the construction piling mud filter cloth, the filter cloth does not need to be removed from the box-type plate and frame filter press, and the pressure in the filter press is used to fully infiltrate, decompose and internally circulate the cleaning agent on the filter cloth adhesion, and clean When the pressure is 0.4Mpa, cleaning time is 60min.

Embodiment 2

[0028] A filter cloth cleaning agent, its raw materials are calculated by mass percentage: 10% hydrochloric acid, 5% oxalic acid, 4% sodium dodecylsulfonate and 3% trisodium phosphate. To clean the filter cloth of municipal sludge and river silt, the filter cloth does not need to be removed from the box-type plate-and-frame filter press, and the pressure in the filter press is used to fully infiltrate, decompose and internally circulate the cleaning agent on the filter cloth adherents , the pressure during cleaning is 0.4Mpa, and the cleaning time is 60min.

Embodiment 3

[0030] A filter cloth cleaning agent, its raw materials are calculated by mass percentage: 6% hydrochloric acid, 5% oxalic acid, 10% sodium dodecylsulfonate, and the rest is water. To clean the filter cloth of municipal sludge and river silt, the filter cloth does not need to be removed from the box-type plate-and-frame filter press, and the pressure in the filter press is used to fully infiltrate, decompose and internally circulate the cleaning agent on the filter cloth adherents , the pressure during cleaning is 0.4Mpa, and the cleaning time is 60min.

Abstract

The invention discloses a filtering cloth detergent and a cleaning method thereof. The filtering cloth detergent comprises the following raw materials in percentage by mass: 2-15% of hydrochloric acid, 2-8% of oxalic acid, 1-15% of sodium dodecyl sulfate and the balance of water. In a mode of low-pressure internal circulation mode of a filter press, filtering cloth sticking substances are washed off with the filtering cloth detergent in an active decomposition manner, the liquid permeation rate can be increased, the service life of filtering cloth can be prolonged, the energy consumption can be reduced, and the productivity can be improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a filter cloth cleaning agent and a cleaning method thereof. Background technique [0002] With the emphasis on environmental protection, a filter press is usually used for solid-liquid separation of mud. The working principle of the filter press is to use a pressure pump to press the mud into the closed filter chamber formed by two adjacent filter plates, so that a pressure difference is formed on both sides of the filter cloth, thereby realizing solid-liquid separation. The filter press generally consists of head plate, tail plate, filter plate, hydraulic cylinder, main beam, transmission and pulling device and other parts. The hydraulic cylinder piston pushes the head plate to make the filter plate press the adjacent filter plate to form a filter chamber; the mud pump sends the mud into the filter chamber, the water permeates the filter cloth and is discharged...
