Abstract
Изобретение относитс к способу получени осветленного раствора гипохлорита кальци , и способствует интенсификации процесса отстаивани гипохлоритной пульпы с образованием осветленного раствора. В пульпу, полученную путем пропускани отход щего хлоргаза через известковое молоко, ввод т 0,8-2,0 мас.% диоксида титана с последующим отстаиванием полученной пульпы и отделением осветленного раствора. Врем отстаивани пульпы сокращаетс в 1,5-2,0 раза, по сравнению с известным способом. 1 табл.The invention relates to a method for producing a clarified solution of calcium hypochlorite, and contributes to the intensification of the process of settling the hypochlorite pulp with the formation of a clarified solution. 0.8-2-2 wt.% Of titanium dioxide is introduced into the pulp obtained by passing the waste chlorine gas through the milk of lime, followed by settling of the obtained pulp and separating the clarified solution. The settling time of the pulp is reduced by 1.5-2.0 times as compared with the known method. 1 tab.
Description
Изобретение относитс к способу получени осветленного ыгюхлорига раствора кальции и может быть использовано в бь товой химии, целлюлозно-бумажной и текстильной промышленности дл отбеливани бумаги, тканей и т дThis invention relates to a process for the preparation of a clarified calcium powder solution and can be used in chemical, pulp and paper and textile industries for the bleaching of paper, fabrics and other materials.
Целью изобретени вл етс интенсификаци процесса отстаивани гипохлоритной пульпы с образованием осветленного раствора.The aim of the invention is to intensify the process of settling hypochlorite pulp with the formation of a clarified solution.
Гипохлоритную пульпу получают на промышленной установке очистки отход щего хлоргаза следующим образом.Hypochlorite pulp is produced in an industrial chlorine gas waste treatment plant as follows.
70 тыс. м / ч отход щего хлоргаза, содержащего 10 г/м С12и 1,5 г/м НС1, пропускают через известковое молоко (130 кг/м СаО), подаваемое со скоростью 8,7 т/ч. Получают гнпохлоритнчю пульпу следующего состава, г/л: Са(ОС1)2 III; СаС12 170; СаСО., 40; СаО 8,6; твердые примеси 50,2; хлораты нет, рН 11.770 thousand m / h of waste chlorine gas, containing 10 g / m С12 and 1.5 g / m HC1, is passed through milk of lime (130 kg / m CaO), fed at a rate of 8.7 t / h. Get gnpohloritnchy pulp of the following composition, g / l: Ca (OC1) 2 III; CaC 170; CaCO., 40; CaO 8.6; solid impurities 50.2; chlorates no pH 11.7
В пульпу ввод т диоксид титана в виде порошка или в виде схспензип в хлоргазе , который барботирчет через извест новое молоко. После этого пульпу отстаивают и отдел ют осветленную часть.Titanium dioxide is introduced into the pulp in the form of a powder or as a suspension in chlorine gas, which is bubbled through known new milk. After that, the pulp is settled and the clarified part is separated.
Пример I. 50 мл гипохлоритной пульпы помещают в мерный цилиндр, разбавл ют вдвое водой, тщательно перемешивают и оставл ют отстаиватьс (по известному способу).Example I. 50 ml of hypochlorite pulp are placed in a measuring cylinder, diluted twice with water, mixed thoroughly and allowed to settle (by a known method).
Примеры 2 - 6. В исходную пульпу ввод т 0,6, 0,8, 1,0, 2,0 3,0 мас.% ТЮо и отстаивают . При этом фиксируют высот осветленного сло в зависимости от времени отстаивани .Examples 2 - 6. 0.6, 0.8, 1.0, 2.0 3.0 wt.% Of TUo are introduced into the initial slurry and settled. In this case, the heights of the clarified layer are fixed depending on the time of settling.
Полученные результаты по примерам 1 6 приведены в таблице.The results obtained in examples 1 to 6 are given in the table.
Из анализа результатов следует. что высота осветленного сло зависит от количества введенного диоксида титана. При количестве ТЮо менее 0,8 мае % скорость отстаивани близка к протомшу. Наибольша скорость отстаивани достигаетс при введении 2,0 мас.% ТЮ. Введение Т1О-.. в количестве более 2.0 мас.% нецелесообразслFrom the analysis of the results follows. that the height of the clarified layer depends on the amount of titanium dioxide introduced. When the amount of TiUo is less than 0.8 May%, the rate of settling is close to the protons. The highest rate of settling is achieved with the introduction of 2.0 wt.% TU. The introduction of T1O- .. in the amount of more than 2.0 wt.% Inappropriate

Таким обра юм, эффективное количество TiO в пульпе должно составл ть 0,8- 2,0 мае %Thus, the effective amount of TiO in the pulp should be 0.8-2.0% by weight.
Таким обра юм, по сравнению с швест ным предлагаемый способ получени осветленного гигюхлорш HOI о раствора позвол ет сократить врем отстаивани пульпы в 1,5 2,0 разаThus, in comparison with the previous one, the proposed method of obtaining a clarified giguichlorsh HOI o solution reduces the time required for settling the pulp by 1.5 to 2.0 times
