[0095] Example 1

[0096] An industrial filter cloth cleaning process, comprising the following steps:

[0097] (1) Rinse with clean water:

[0098] Put the oil-stained industrial filter cloth into the cleaning room, and use a water gun to wash the surface of the industrial filter cloth to remove large particles of oil and stains on the surface of the industrial filter cloth; the surface washing time is 20 minutes.

[0099] (2) Preparation of sludge liquid:

[0100] The active sludge was added to the salt solution, stirred at 500 r / min for 40 minutes, then kept at 30°C for 4 hours, filtered to remove large solid impurities, and the obtained filtrate was the sludge liquid; the active sludge and salt The mass ratio of solution mixing is 100g:1000mL. The salt solution is sodium dodecyl sulfate solution; the mass fraction of the sodium dodecyl sulfate solution is 1.2%.

Abstract

The invention discloses an industrial filter cloth cleaning process and relates to the technical field of industrial filter cloths. The preparation method comprises the following steps: (1) washing with clear water, (2) preparing sludge liquid, (3) carrying out sludge liquid treatment, (4) carrying out fumigation, and (5) carrying out alkali washing. When the sludge liquid is prepared, large-particle solid impurities in the sludge liquid can be removed through filtering treatment, and the sludge liquid is prevented from blocking filter holes of industrial filter cloth. The industrial filter cloth is soaked in the prepared sludge liquid, microorganisms in the sludge liquid can decompose greasy dirt on the surface of the industrial filter cloth to generate easily-dissolved substances, the adhesive force between the greasy dirt and the industrial filter cloth can be reduced, then ultrasonic treatment is conducted, the greasy dirt can be promoted to be separated from the industrial filtercloth, and especially the greasy dirt separation efficiency in filter holes of the industrial filter cloth is higher.

Description

technical field [0001] The invention belongs to the technical field of industrial filter cloths, in particular to an industrial filter cloth cleaning process. Background technique [0002] Due to the high content of oil mist in the atmosphere of the metal processing workshop, the air quality in the workshop is poor, which poses a great threat to the health of the operators. Therefore, it is necessary to purify the air in the workshop. [0003] In the prior art, the air in the workshop is generally treated by mechanical filtration and purification, and the industrial filter cloth is used for direct filtration treatment, and the oil mist particles in the air are blocked on the surface of the industrial filter cloth through inertial collision and direct blocking. However, in the After a period of filtration, due to the saturated state of oil mist particles, the filtration becomes invalid and cannot continue to be effectively filtered. Therefore, the filter cloth needs to be cle...
