Background

Before the strip steel is subjected to post-process treatment such as annealing, coating and the like, a degreasing section is required to be arranged for cleaning grease on the surface of the rolled strip steel. During normal production, degreasing fluid (also commonly called lye) is recycled between an alkaline washing tank and a lye circulating tank, and as the lye generally contains alkali, surfactant and other components, a large amount of foam is inevitably generated under the external conditions of air mixing, scouring and stirring, and finally the foam is accumulated in the lye circulating tank. Excessive foam can overflow from the lye circulating tank, which not only causes the loss of effective components in the lye, influences the degreasing effect, increases the production cost, but also pollutes the operation environment of the cleaning section.

In order to eliminate excessive foams in the alkali liquor, defoaming is mostly carried out by adding a defoaming agent into the alkali liquor at present, but the method not only increases the production cost, but also accelerates the blockage of a nozzle and influences degreasing production because the defoaming agent is insoluble or slightly soluble in the alkali liquor and often exists in particles with a certain size. In addition, organic silicon or polyether and other organic matters which are difficult to degrade and contained in the defoaming agent enter the alkali liquor, so that the alkali liquor pollution is caused, and the treatment difficulty of the failed alkali liquor is increased.
