Abstract
Description
Изобретение относится к химической технологии и может быть использовано при производстве бората кальция из борсодержащих растворов. The invention relates to chemical technology and can be used in the production of calcium borate from boron-containing solutions.
Целью изобретения является увеличение срока службы фильтроткани. The aim of the invention is to increase the service life of filter cloth.
П р и м е р. Борсодежащий раствор в количестве 80 м3/мол обрабатывают прокаленной датолитовой рудой и осветляют в отстойнике. В осветленный раствор, содержащий, B2O3 1,95; CaO 0,27; SiO2 0,013; SO4 - 0,24, с рН 7,2, добавляют карбонизированный маточный раствор после осаждения из него бората кальция, содержащий, B2O3 0,24; CaO 0,17; SiO2 0,0005; SO4 - 0,17 и мела 10,6 г/л. Дозировка маточного раствора при добавлении к осветленному раствору в количестве 5 мас. составляет 4 м3/ч. После этого раствор подвергают контрольному фильтрованию на фильтр-прессе с намывкой на фильтровальной перегородке фильтрующего слоя из мела, содержащегося в карбонизированном растворе. 1 раз в смену обработанный слой мела, содержащий выпавшие на нем соединения кальция и задержанные частицы прокаленной датолитовой руды, смывают водой и направляют в отвал.PRI me R. A boron-containing solution in an amount of 80 m 3 / mol is treated with calcined datolite ore and clarified in a sump. In a clarified solution containing, B 2 O 3 1.95; CaO 0.27; SiO 2 0.013; SO 4 - 0.24, with a pH of 7.2, add carbonated mother liquor after precipitation from it of calcium borate, containing, B 2 O 3 0.24; CaO 0.17; SiO 2 0.0005; SO 4 - 0.17 and chalk 10.6 g / l. The dosage of the mother liquor when added to a clarified solution in an amount of 5 wt. is 4 m 3 / h. After that, the solution is subjected to control filtration on a filter press with washing on the filter baffle of the filter layer from chalk contained in the carbonized solution. Once per shift, the treated chalk layer containing calcium compounds deposited on it and trapped particles of calcined datolite ore is washed off with water and sent to the dump.
После фильтрования в раствор добавляют известковое молоко и осаждают борат кальция. Борат кальция отделяют от маточного раствора и последний подвергают карбонизации. After filtering, milk of lime is added to the solution and calcium borate is precipitated. Calcium borate is separated from the mother liquor and the latter is carbonized.
В таблице представлены результаты опытов по фильтрованию борсодержащих растворов. The table shows the results of experiments on filtering boron-containing solutions.
Сравнение предлагаемого способа с прототипом показывает, что срок службы фильтроткани увеличивается в 2,5 раза и сокращается расход бельтинга и капрона соответственно с 1,1 и 0,30 до 0,45 и 0,15 пог. м/т бората кальция. Comparison of the proposed method with the prototype shows that the service life of the filter cloth increases by 2.5 times and reduces the consumption of belting and kapron, respectively, from 1.1 and 0.30 to 0.45 and 0.15 linear meters. m / t calcium borate.
