Description

The image-taking system of graininess sicker in papermaking pulp-liquor

Technical field

This utility model relates to pulp and paper technology field, particularly relates to graininess sicker in a kind of papermaking pulp-liquor Image-taking system.

Background technology

Current pulp and paper industry is faced with a problem the most serious: how to control Stickies deposit to production Process and the harmful effect of product quality.These sickers are essentially from three aspects: one is natively to exist in paper-making fibre Lipophilic substance, such as fatty acid, resinic acid, fatty acid ester, sterol and sterol ester etc.；Two when being with regenerated papermaking, waste paper this The materials such as the coating adhesive of body introducing, printing-ink, PUR, pressure sensitive adhesive；Three is some added in pulping and papermaking processes Chemical drugs, such as reinforcing agent, sizing agent, defoamer and filler etc..

When Stickies deposit is on forming net, blocking mesh can be produced, cause drainage difficulty, increase the stop cleaning time etc. Problem；If deposited on squeezing felt-cloth and pressure roller, felt service life can be shortened, and affect page drainage；If sicker Stick to dryer surface, page broken end can be caused or form paper hole, sheet hole；If sicker remains in page, can be formed Stain, increases paper defects；If sicker is gathered in plain boiled water, become " anionic trash ", affect the use of Cationic aid Effect, hinders the circulating and recovering of plain boiled water.

Therefore, pulp and paper industry applies various methods to control the harmful effect that sicker is brought.These methods master Mechanical Method to be had and chemical method, in addition with biochemical process etc..Wherein, Mechanical Method be application sieve, remove the gred, wash, the work such as flotation Sicker granule is separated from paper making pulp by skill；Or the techniques such as application is rubbed, dispersion are to reduce sicker granule Particle diameter, thus lower the hazardness of sicker.Chemical method be in paper making pulp add dispersant, determine agent, detackifier, absorption The chemical reagent of the difference in functionalitys such as agent, to reduce the hazardness of sicker dye thing；Or directly should abluent or clean-preserving agent For the surface of pulping and papermaking equipments, as forming net, press felt, drying cylinder and dry net, etc., with remove be deposited on these equipment The sicker on surface, or stop sicker to deposit on the surface of these equipment.Biochemical process is with enzyme substituted chemistry product Some Main Ingredients and Appearance degraded or be passivated in sicker, thus weaken the hazardness of sicker.Such as, fat hydrolase is used Can degrade the fatty acid ester in sicker, the polyvinyl acetate in sicker can be hydrolyzed with biopolyester hydrolytic enzyme, and use acyl Amine enzyme can hydrolyze the polyamide hot in sicker.

Sicker in pulp and paper production can be divided into two big classes according to their particle size: size > 0.10mm or > 0.15mm for macro stickies (macrostickies), otherwise, less than this size for microstickies (microstickies).And according to sicker generating mode, can be divided into again primary stickies (primarystickies) and Secondary sicker (secondary stickies).Primary stickies refers to those glue directly brought from the raw material of pulping and paper-making Viscous thing；Secondary sicker be then scattered or dissolved gum glue thing reassemble or with other components in paper making pulp (such as paper making additives such as sizing agent, reinforcing agent, retention and drainage aid agent, defoamer) combines and is formed.Macro stickies is generally Can be with sieving and the method such as slagging-off removes, microstickies is in addition to can getting rid of a part by the method for washing, often Also need to control their hazardness with chemical method or biochemical process.

Obtaining the image of sicker granule in paper making pulp, this is significant for pulping and papermaking processes.Application image Processing system analyzes acquired image, it is provided that the many information of sicker in pulp and paper production, such as sicker Relative amount, sicker mean particle size and particle diameter distribution, the shape of sicker granule and color, etc..These letters Breath provides important foundation for the harm controlling sicker.Additionally, the image of sicker granule can also be as being prone to protect The image document deposited adds in existing numeral and writing record, increases the pulping and paper-making record of production and experimental record further Reliability and credibility.

About obtaining the image of sicker granule in paper making pulp, being most recognized method has: pulping and paper-making association of the U.S. Method T277om-07 (Macro stickies content in pulp:the " pick-up " method) of meeting (TAPPI), Method Ingede of international deinking TIA (International Association of Deinking Industry) Method 4 (Analysis of Macrostickies in Pulps), and international standard 15360-2 (Recycled Pulp-Estimation of Stickies and Plastics-Part 2:Image Analysis Method).These sides Method is by the wedge wire screen that screen slot is 0.1mm or 0.15mm by the paper pulp containing sicker, makes macro stickies granule and paper pulp Fiber separately, and the macro stickies (macro stickies) separated is filtered on the filter paper of black.Then having One layer of white coating, then the image with scanner scanning sicker is covered on the sicker of viscosity.But, this method only limits In the image of the particle diameter that can the collect macro stickies granule more than 0.1mm or 0.15mm, for particle diameter less than this size Tiny sicker granule then will be left in the basket.Additionally, this method is when scanning the image of macro stickies, first all sickers Grain changes into white, thus cannot be distinguished from the sicker granule of different colours and character.

U.S. Patent number US9280726 teaches on-line analysis device and the method for big pollutant in a kind of paper pulp/plain boiled water.Root According to this method, first the macro stickies granule in paper pulp/plain boiled water is separated, then gluing with a slurry grader Composition granule suspension is in water, and shoots the sicker particle image being suspended in water with photographing unit, finally uses computer software Analyze quantity and the total amount of sicker granule in image.But, the method is also only limited to measure in paper making pulp or plain boiled water Macro stickies.

U.S. Patent number US8160305 teaches a kind of for measuring the side that in pulp and paper slurries, particulate pollutant measures Method and device.According to this method, first, a piece of substrate is inserted in paper making pulp after certain time, takes out substrate, with one Imaging system catches the particle contamination object image being deposited in substrate, then the granule in image is counted and is measured, After add in the slurry inhibitor process pollutant.The imaging system that this method uses includes optical scanner, numeral or glue Sheet video camera or with reflecting microscope with the use of numeral or film camera.But, this method is not related to how district Divide the contaminant particle of different colours in paper making pulp.

《Real-time in-line measurement of stickies in recycled pulp》(Suvajit Das, PEERS 2014, Tacoma, Washington) literary composition teach a kind of On-line sampling system reclaim paper pulp sicker side Method and device.This method is to allow slurry sample observe pond by one, simultaneously with the image of high-speed figure camera shooting slurry sample, then Analyze slurry sampled images with special computer software, thus detect the sicker granule in pulp sample.This method needs to depend on Rely complicated computer-processing software to differentiate the foreign body in slurry sampled images to be belonging to sicker and still fall within other foreign material, and This special computer software needs through artificial " training ".U.S. Patent Application No. US20140293040 also teaches A kind of similar method and apparatus, except that, this method is that shooting is deposited on the granule observed on the window of pond Image rather than the image of slurry sample.

But, generally speaking, up to now, the most perfect method obtains the image of sicker granule.? It is complexity and the multiformity ignoring sicker granule for serious defect.Almost all of method is all or all glue Viscous composition granule is transformed into same color and scans, or obtains sicker particle image under single background.Such as, Sicker granule usually has white and black mixed in together.If only carrying out scanogram by the background of white, may be just The granule of white can be have ignored.Whereas if only with the background scans of black, the granule of black may will be ignored.
