The on-line acid-base cleaning method for kinds of coarse cotton cloth is characterized by comprising alkali washing and acid washing, wherein the alkali washing is 5% alkali washing, and the acid washing is 3% acid washing.

2, kinds of felt online acid-base cleaning method, which is characterized in that it comprises the steps of step of preparing 5% caustic soda and 3% citric acid by dissolving and diluting, and the second step of cleaning pressing and secondary pressing felt by pressing spray pipe.

3. The on-line acid-base cleaning method of kinds of coarse cotton cloth according to claim 2, wherein the 5% caustic soda washing time is 20 min.

4. The on-line acid-base cleaning method of kinds of coarse cotton cloth according to claim 2, wherein the 3% citric acid washing time is 10 min.

Technical Field

The invention relates to the technical field of papermaking, in particular to an on-line acid-base cleaning method for coarse cotton cloth.

Background

The felt is in using to middle and later stages, more organic matter, the adhesion of inorganic matter impurity is in the felt, can't realize the effect of clean felt through online clean mode, often use chemical to shut down in the production and wash the felt, get rid of the pollutant of a large amount of adhesions in the felt, resume the dewatering capacity of felt, traditional felt washing is to wash the felt with 5% alkali lye, but can only remove alkali soluble thing, like starch, dry strength agent, rotten thick liquid deposit etc. to acid soluble thing, like calcium carbonate, fatty acid salt etc. and can not drop. Through the operation of alkali washing and acid washing, the service life of the coarse cotton cloth is prolonged, the maintenance frequency can be reduced, and the time efficiency of the paper machine is inevitably improved.

Disclosure of Invention

The invention aims to provide kinds of coarse cotton cloth online acid-base cleaning methods aiming at the defects and shortcomings of the prior art, the cleaning effect of the coarse cotton cloth provided by the invention is superior to that of single alkali cleaning, the service life of the coarse cotton cloth can be prolonged, the maintenance frequency can be reduced, and the time efficiency of a paper machine can be improved.

In order to achieve the purpose, the invention adopts the technical scheme that the wool cloth online acid-base cleaning method comprises alkali cleaning and acid cleaning, wherein the alkali cleaning is 5% alkali cleaning, and the acid cleaning is 3% acid cleaning.

method for cleaning coarse cotton cloth on line by acid-base method includes such steps as dissolving 5% caustic soda and 3% citric acid in , and washing -pressing coarse cotton cloth by spraying pipe.

The 5% caustic soda serial washing time is 20 min.

The 3% citric acid serial washing time is 10 min.

After the technical scheme is adopted, the invention has the beneficial effects that: the cleaning effect of the felt provided by the invention is better than that of single alkali cleaning, so that the service life of the felt can be prolonged, the maintenance times can be reduced, and the time efficiency of a paper machine can be improved.
