Abstract
Изобретение относится к способам очистки природных и сточных вод, а также иных жидких растворов с помощью ионообменных фильтров, а именно к способам регенерации ионообменных смол (ИС), и может быть использовано в энергетике, металлургии, химической и других отраслях промышленности, применяющих обессоленную или умягченную воду в технологических процессах. Предлагается модифицированный способ регенерации ионитов в фильтрационных процессах типа "UPCARE", включающий в себя стадию зажатия слоя ионита потоком жидкой среды, направленным снизу вверх, в котором процесс зажатия осуществляют в импульсном режиме, подавая воду, по крайней мере, двумя импульсами, причем амплитуда первого импульса составляет не менее высоты зоны свободного пространства над слоем ионита при завершении рабочего цикла, а амплитуда последующего импульса - не менее амплитуды отраженной волны, возникающей после прохождения предыдущего импульса, а время между импульсами - не более времени, необходимого для прохождения отраженной волны от предыдущего импульса через слой ионита. Использование заявленного способа обеспечивает возможность более полного удаления загрязнений из слоя ионита и соответственно более высокую эффективность процесса его регенерации. Затраты времени на регенерацию при этом сокращаются в среднем на 5-7% в зависимости от природы и срока службы ионита. Затраты воды на собственные нужды сокращаются на 10-12%.The invention relates to methods for purifying natural and wastewater, as well as other liquid solutions using ion-exchange filters, and in particular to methods of regeneration of ion-exchange resins (IP), and can be used in energy, metallurgy, chemical and other industries using desalted or softened water in technological processes. A modified method for the regeneration of ion exchangers in filtration processes of the UPCARE type is proposed, which includes the stage of clamping the ion exchanger layer by a liquid flow directed from the bottom up, in which the clamping process is carried out in a pulsed mode, supplying water with at least two pulses, the amplitude of the first the pulse is not less than the height of the free space zone above the ion exchanger layer at the end of the working cycle, and the amplitude of the subsequent pulse is not less than the amplitude of the reflected wave that occurs after passing n edyduschego pulse and the time between pulses - no more than the time required for passage of the reflected wave from the preceding pulse through the resin bed. Using the claimed method provides the possibility of more complete removal of contaminants from the ion exchanger layer and, accordingly, a higher efficiency of the process of its regeneration. The time spent on regeneration is reduced by an average of 5-7%, depending on the nature and life of the ion exchanger. The cost of water for own needs is reduced by 10-12%.
