Description
Technical Field
The invention relates to a device for adsorbing resin and adhesive in the pulping and papermaking process, and belongs to the technical field of pulping and papermaking equipment.
Background
Wood raw materials contain small amounts of nonvolatile lipophilic extractives, called wood resins, in addition to cellulose, hemicellulose and lignin. During pulping, especially during the production of mechanical pulp, these resin components are dispersed as colloidal droplets into a pulp water system with a particle size of between about 0.1 and 0.2 μm and a total colloidal resin content in the suspension of between 5 and 70mg/kg at a pulp concentration of 1%. They are used in pulp washing, screening and bleaching stages, where resin in the pulp can deposit on the surfaces of ducted pumps and augers in pulp flows; the paper making section is deposited on the blanket, the forming net, the vacuum water absorbing tank, the head box and the like. Which jeopardizes the runnability of the machine and the quality of the sheets.
The deposition of resin in pulping affects the pulping and papermaking process in two main ways. First, the deposition of resin reduces breakage of the runnability sheet of the pulp and frequent cleaning and maintenance of the equipment increases downtime. Secondly, dust is formed on the paper pulp which is deposited and shed by the resin, so that the quality of the product is affected; thirdly, the coarse cloth and the net of the pulp machine are adhered by resin, and the service life of the net blanket is reduced due to frequent alkali washing. Resin obstructions in the pulping process are mainly generated by the deposition of resin components in the pulping on the surfaces of equipment in various forms, so the control of the resin obstructions in the pulping and papermaking process is essentially the control of resin deposits.
With the development of the pulping and papermaking industry, the problem of resin precipitation is increasingly prominent, which is mainly determined by the following factors: (1) Environmental aspects show that the closed system of water is increasingly perfect, so that the water contains higher concentration of resin; (2) The increase of the secondary fiber dosage introduces more resin pollutants; (3) The increase in the speed of the paper machine increases the shear rate, thereby increasing the deposition tendency of the resin; (4) The improvement in the capacity of paper mills has led to the overload of equipment such as washers, resulting in pulp containing more resin components. In addition, the expansion of raw paper materials, the addition of papermaking aids, and the increase in mechanical pulp production, all present more complex and serious problems with resin deposition in pulping and papermaking enterprises.
At present, for the problem of resin deposition in the pulping and papermaking process, the most widely adopted is to use a resin remover and a resin dispersant to chemically remove resin in a specific pulping and papermaking process (impregnation stage after pulp bleaching and before pulping). However, the addition of various anionic-containing papermaking aids can cause the accumulation of anionic species due to the recycling of the papermaking white water and the increase in the degree of blocking. This accumulation can also have an adverse effect on the papermaking wet end chemistry: (1) affects the effectiveness of papermaking retention aids; (2) affecting the uniformity and physical strength of the paper. In the traditional technology, the resin is removed by physical and mechanical methods, such as adding a detergent to a high-pressure water gun stuck on a paper machine net or a blanket, even manually removing the resin at fixed points, and the method of removing the resin by physical and mechanical methods such as scraping, wiping, even cleaning the resin by a scraper stuck on the surface of a paper machine cylinder or a roller is simply carried out physical adsorption, so that the resin removal efficiency is low and the treatment effect is not obvious because the resin removal methods need shutdown treatment.
Therefore, no treatment method which really and completely solves the problems of resin precipitation and stickies and has low consumption and high efficiency exists up to the present. The paper industry is very desirous of an economical and efficient technique to solve the problem of resin precipitation which plagues paper production for many years.
