Abstract
Description
Изобретение относится к способам получения сорбентов и адсорбентов на основе пористых материалов и может быть использовано для очистки промышленных газов, а также поглотителя запахов и влаги в бытовых воздухоочистителях, как гигиенический наполнитель, например, для кошачьих туалетов и других нужд. The invention relates to methods for producing sorbents and adsorbents based on porous materials and can be used for purification of industrial gases, as well as an odor and moisture absorber in household air purifiers, as a hygienic filler, for example, for cat's toilets and other needs.
Известен способ получения адсорбентов на основе диатомитовых земель при пропитке их серой в диосульфите углерода или водным раствором сульфата железа при температуре от 100oC до 400oC (см. заявку Японии N 61-238338 B 01 J 20/10, 1986 г.).A known method of producing adsorbents based on diatomaceous earths by impregnating them with sulfur in carbon diosulfite or an aqueous solution of iron sulfate at a temperature of from 100 o C to 400 o C (see Japanese application N 61-238338 B 01
Недостатками известного способа являются узкая направленность адсорбента и экологическая опасность при его проведении. The disadvantages of this method are the narrow orientation of the adsorbent and the environmental hazard during its implementation.
Известен также способ получения сорбента, включающий дробление пористого силикатного носителя, насыщение раствором модифицирующего реагента-сульфата алюминия, сульфата железа (III), сульфата аммония, перманганата калия или их комбинации. Последующую термообработку осуществляют при температуре разложения модифицирующего реагента (см. описание к патенту РФ N 2031705, B 01 J 20/30, 20/10, 1995 г.). There is also known a method of producing a sorbent, including crushing a porous silicate carrier, saturation with a solution of a modifying reagent-aluminum sulfate, iron (III) sulfate, ammonium sulfate, potassium permanganate, or a combination thereof. Subsequent heat treatment is carried out at the decomposition temperature of the modifying reagent (see the description of the patent of the Russian Federation N 2031705, B 01
Недостатками известного способа является то, что как адсорбент он не может эффективно использоваться для очистки газов, не может поглощать запахи. The disadvantages of this method is that as an adsorbent, it cannot be used effectively for gas purification, cannot absorb odors.
Технической задачей, на решение которой направлено изобретение, является повышение эффективности адсорбционных свойств получаемого материала для очистки и поглощения запахов. The technical problem to which the invention is directed is to increase the efficiency of the adsorption properties of the obtained material for cleaning and absorbing odors.
Поставленная техническая задача достигается включающим дробление пористого силикатного носителя и термообработку, перед дроблением производят сушку для удаления избыточной влаги из носителя. В качестве пористого силикатного носителя берут диатомит. Последующую термообработку для носителя из мелкодисперсных частиц ведут при температуре достаточной для удаления потери при прокаливании (п.п.п.) и придания механической прочности грануле, которая находится в интервале 550 - 650oC.The stated technical problem is achieved by crushing the porous silicate carrier and heat treatment, before crushing, drying is performed to remove excess moisture from the carrier. As a porous silicate carrier, diatomite is taken. Subsequent heat treatment for the carrier of fine particles is carried out at a temperature sufficient to remove loss on ignition (p.p.p.) and impart mechanical strength to the granule, which is in the range of 550 - 650 o C.
Данные температурные пределы установлены экспериментально. These temperature limits are established experimentally.
Способ осуществляли следующим образом:
Примеры.The method was carried out as follows:
Examples.
Минеральное пористое силикатное сырье доставили на склад, где оно вылеживалось в течение двух недель. В течение этого времени производилась естественная сушка сырья, в результате которой влажность снизили с 33% до 20%. Далее его дробили на конусной дробилке до фракции 0-5 мм. Полученную фракцию подвергали термообработке в барабанной печи. Затем после термообработки классифицировали до товарной фракции в пределах 0,5 - 5,0 мм. Mineral porous silicate raw material was delivered to a warehouse where it was aged for two weeks. During this time, the raw materials were naturally dried, as a result of which the humidity was reduced from 33% to 20%. Then it was crushed on a cone crusher to a fraction of 0-5 mm. The obtained fraction was subjected to heat treatment in a drum furnace. Then, after heat treatment, they were classified to a commercial fraction in the range of 0.5 - 5.0 mm.
Последующие примеры 2 и 3 с диатомитом по своей сущности аналогичны примеру 1 с опокой, а их режимные параметры представлены в таблице
Полученный таким образом адсорбент имеет следующие характеристики:
Объемный вес, кг•м3 - 590 - 620
Удельная поверхность, м2•г - 150 - 200
Водопоглощение,% - 65 - 90
Прочность, МПа - 1,5 - 3,0
Истираемость,% - 0,5
Заявляемый адсорбент использовали для очистки промышленных газов на ряде Уральских заводах, где были получены хорошие результаты по улавливанию серного и сернистого ангидрида, фторосодержащих компонентов, оксида, диоксида азота и др.The following examples 2 and 3 with diatomite are essentially the same as flask example 1, and their operational parameters are presented in the table
Thus obtained adsorbent has the following characteristics:
Volumetric weight, kg • m 3 - 590 - 620
Specific surface, m 2 • g - 150 - 200
Water absorption,% - 65 - 90
Strength, MPa - 1.5 - 3.0
Abrasion,% - 0.5
The inventive adsorbent was used to purify industrial gases at a number of Ural plants, where good results were obtained on the capture of sulfuric and sulfur dioxide, fluorine-containing components, oxide, nitrogen dioxide, etc.
Полученный адсорбент использовали и как гигиенический наполнитель для кошачьих туалетов. Результат - подстилка толщиной 3-4 см, поглощает запах в течение недели. The obtained adsorbent was also used as a hygienic filler for cat's toilets. The result is a 3-4 cm thick litter that absorbs odor for a week.
