Description

Head box for anionic garbage control system of papermaking system

Technical Field

The utility model relates to the technical field of anion garbage treatment, in particular to a head box for an anion garbage control system of a papermaking system.

Background

With the large-scale high-speed development of paper machines and increasingly strict environmental requirements, the production cost is reduced due to factors such as gradual shortage of raw material resources, and the like, and the stability of a wet end system of the paper machine is adversely affected by measures such as large-scale adoption of waste paper, improvement of the closed circulation degree of white water of the paper machine, and the like. Particularly in the production of the cardboard paper with the waste paper fiber utilization rate of more than 90%, the recycling of the waste paper fiber causes serious fiber strength loss, more and more barrier substances are attached to the pulp, the whole wet end environment is more and more complicated, and the problem caused by the accumulation of anionic garbage is more and more concerned. Anionic trash refers to the collective name of all dissolved and anionic polymeric (oligomeric and polymeric) and colloidal anionic species present in the wet end of the paper machine. Due to the requirements of water saving and environmental protection, the degree of white water sealing of modern paper machines is increased more and more, and because most of the suspension and dissolved matters in the white water have anionic charges, the closed circulation of the white water can cause more and more anionic trash in the system to accumulate along with the circulation of the white water, thereby causing serious anionic trash problems. The experimental study of scholars shows that when the content of the anionic trash is more than 0.1%, the filler is greatly reduced, which can greatly affect the quality problem of paper and cause other problems to affect the production efficiency of a paper machine, for example, the change of the paper strength causes the increase of the number of broken ends of the paper machine, thereby affecting the running performance of the paper machine.

The formation of anionic trash is complicated and difficult to avoid, and the size of the anionic trash is almost less than 10 μm, so that the anionic trash is one of the problems which need to be solved urgently in the pulp and paper making at present. In anion refuse treatment process, often use the head box to separate paper pulp and anion rubbish, but when the actual separation, generally all utilize the filter screen to separate paper pulp and anion rubbish, this kind of separation mode not only can cause the slow of paper pulp outflow, and the mixture of simultaneous treatment agent and paper pulp is inhomogeneous to reduce the separation effect, and the filter screen often can take place to block up simultaneously, influences in-service use.
