Description
Известен способ контрол содержани волокна в оборотных и сточных водах целлюлозно-бумажного производства путем измерени интенсивности света, прошедшего сквозь систему пол ризатор - контролируема среда - анализатор.There is a known method for controlling the fiber content in circulating and wastewaters of pulp and paper production by measuring the intensity of light transmitted through a polarizer-controlled medium-analyzer.
Однако при этом способе на получаемый результат вли ют неволокнистые взвеси и растворенные вещества.However, this method is influenced by non-fibrous suspensions and solutes.
Предложенный способ отличаетс от известного тем, что дополнительно измер ют интенсивность естественного света, прошедшего сквозь контролируемую среду, и сравнивают ее с интенсивностью света, прошедшего сквозь систему пол ризатор - контролируема среда - анализатор.The proposed method differs from the known one in that it additionally measures the intensity of natural light transmitted through a controlled medium and compares it with the intensity of light transmitted through a polarizer-controlled medium-analyzer system.
Предлагаемый способ позвол ет исключить вли ние неволокнистых взвесей и растворенных веществ на получаемый результат.The proposed method makes it possible to eliminate the influence of non-fibrous suspensions and solutes on the result obtained.
На чертеже показана принципиальна схема дл осуш,ествлени описываемого способа.The drawing shows a schematic diagram for drying, describing the described method.

Прозрачную емкостьThe light from the source / using mirrors 2, 3 and capacitors 4, 5 is divided into two parallel beams. One of the beams passes through the polarizer 6, the analyzer 7 and enters the (b cell 8, 9. Transparent capacity
10,по которой проходит контролируема суспензи , размещают между пол ризатором и анализатором. Сквозь нее проход т оба пучка света - пол ризованный и естественный.10, through which the controlled suspension passes, is placed between the polarizer and the analyzer. Both beams of light, polarized and natural, pass through it.
Пучки света, воздейству на фотоэлементы, вызывают возникновение фототоков, пропорциональных интенсивност м световых потоков.Light beams affecting photovoltaic cells cause photocurrents that are proportional to the intensity of light beams.
Это отношение регистрируют индикаторомThis ratio is recorded by the indicator.

Предмет изобретени Subject invention
Способ коптрол содержани волокна в оборотных и сточных водах целлюлозно-бумажного производства путем измерени интенсивности света, прошедшего сквозь систему пол ризатор - контролируема среда - анализатор , отличающийс тем, что, с целью исключени вли ни неволокнистых взвесей и растворенных веществ на получаемый результат , измер ют интенсивность естественного света, прошедшего сквозь контролируемую среду, и сравнивают ее с интенсивностью света , прошедшего сквозь систему пол ризатор - контролируема среда - анализатор.The method of Coptrol fiber content in the circulating and waste waters of pulp and paper production by measuring the intensity of light transmitted through the polarizer-controlled medium-analyzer, characterized in that, in order to eliminate the effect of non-fibrous suspensions and dissolved substances on the result, measured the intensity of natural light transmitted through a controlled medium and compares it with the intensity of light transmitted through a polarizer – controlled medium – analyzer system.
