Technical field
The utility model relates to a kind of defoaming device.
Background technology
Paper industry technical need has determined to need large water gaging to carry out loosen collagen fibre.Even in ancient method papermaking, also inevitably need to introduce various biomass materials so that page is more easily manufactured paper with pulp or obtained other functions, and various colloidalmaterials are introduced in the use of biomass material feedwater, affect the reusable edible performance of water.
Raw material, machinery, chemical industry medicine become the pacing factor of modern paper.Primary slurry is mainly from wood materials, and along with the raising of environmental consciousness, its use is restricted.The utilization of recycled writing paper has also been raised to unprecedented height thereupon, and in recycle, these wood fibre forms are constantly destroyed, and its intensity also weakens thereupon.Now need the interfibrous bonding strength of the auxiliary raising of a large amount of pharmaceutical chemicalss, meet people's user demand.And the introducing of difference in functionality chemical causes paper waste to be processed into a problem of an industry tackling key problem, the introduction of pharmaceutical chemicals constantly brings challenges to wastewater treatment, has also polluted the quality of recycle water simultaneously.
Involved pharmaceutical chemicals in papermaking, majority contains interfacial activity composition, for the condition that provides is provided plain boiled water foam.No matter enhance productivity or improve fiber bonding strength (improving paper strength performance), all needing to add various pharmaceutical chemicalss to achieve the goal.Wait until that from sodium stearate, the deinking agent of slurrying medicine that wet end of machine uses is as: modified starch, retention filtration adjuvant, dry/Wet Strength Resin etc.These medicines are to have an effect by the active group in polymer invariably, and these have high surface composition and remain in water, and also feedwater circulation makes troubles.Their residual activity in water, because liquid level turbulence and air produce bubble and be difficult for breaking, are taken more colloidalmaterials simultaneously out of and are separated out, and must introduce defoamer solution bubble-related issues for not affecting water circulation use.The application of defoamer has increased the content of anionic trash to system, anionic trash has consumed the cationic active ingredients adding in medicine, need to add polycation medicine more just can reach enhancing, the retention and drainage effect of needs.Then in water, produce more foams, need to add more defoamers, form vicious cycle.Therefore how to reduce the important topic that system anionic trash has become papermaking research, wherein adding the aluminum ion of high electric charge is a research direction by aluminum ion complexing action reduction anionic trash activity.But aluminum ion is conventionally taking Tai-Ace S 150, polymerize aluminum chloride as carrier, and Tai-Ace S 150 reduces system pH, and paper feeding machine causes corrosion, reduces work-ing life; Aluminum chloride activity is too strong, can cause wadding poly-, unfavorable in producing equally.
Papermaking expert also solves bubble-related issues by increase HP shower, degasifier, cell body overflow.But facts have proved that these physical methods are to foam removal effect not obvious, also not obvious to the effect of reduction defoamer consumption.Degasifier effect wherein obviously but its volume is large, processing power is limited, thereby is difficult to promote scale and uses.Studying carefully its underlying causes, is because the colloidalmaterial in medicine, system residual in water gathers at the water surface, separates out the fine solid substance in water simultaneously, causes foam to be difficult to eliminate.Therefore adopt above-mentioned coarse physics bubble removing method can not obtain effect.
