Description
Изобретение относитс к решеткам, предназначекным дл использовани в аппаратах, в которых они примен ютс дл физической или химической обработки текучих сред. Более конкретно оно касаетс средств, позвол ющих поддерживать такие решетки в первоначально установленном горизонтальном положении независимо от температуры, измен ющейс в широкоА интервале. Среди технических решений, известных в этой области техники можно выделить такие pemienHfl,. в которых технологические н конструктив1 ые функции материала решетки совмещены и решетка представл ет собой цельный узел аппарата. Таким решением в.а етс , например, решетка , выполненна из предварительно напр женных пружин, материал которых подбирают по технологическим услови м {. Такие ренгени нецелесообразны в случа х, когда решетку выполн ют из драгоценных или редких материалов. Д.л таких случаев известны решетки, в которых задачи прочности и устойчивости решают посредством отдельного опорного узла. Наиболее близкой к предлагаемому изобретению вл етс рсгиетка, выполненна из сетки, размещенной на подложке, укрепленной в рамке и выполненной из параллельных проволочных элементов, св занных с нат жным устройством (2). Однако недостатком этой peujeTKH вл етс то, что нат жение проволочных элементов подложки осуществл етс независимо от изменени свойств материалов, из которых они изготовлены . Это означает, что температурный .диапазон применени таких решеток ограничиваетс свойствами примен емых материалов, в частности пределом текучести, и модулем упругости. Целью изобретени вл етс расширение температурных пределов применени решеток за счет устранени указанного недостатка подложки . Эта цель достигаетс тем, что проволочные опорные элементы подложки выполнены в виде винтовых спиралей и витки соседних спиралей соединены между собой. На фиг. 1 дано частичное изображение пред, лагаемой решетки, поперечный разрез; на фиг. 2 - схематическое изображение части подложки. Решетка, например круглой формы, состоит из каталитической сетки J, уложенной на подложку 2, опорные элемр1 Т1..1 3 которой выпо.чмоны в виде спиралей из одной или нескольких, например двух, проволок (см. фиг. 2) и размещены в одной плоскости параллельными р дами . Витки соседних спиралей сцеплены между собой, например, способом завинчивани одиоЙ 5 спирали в другую.The invention relates to gratings intended for use in apparatus in which they are used for the physical or chemical treatment of fluids. More specifically, it relates to means allowing such grids to be maintained in the originally established horizontal position regardless of temperature, varying in the wide interval. Among the technical solutions known in this field of technology such pemienHfl, can be distinguished. in which technological and constructive functions of the lattice material are combined and the lattice is an integral unit of the apparatus. This solution is, for example, a lattice made of prestressed springs, the material of which is selected according to the technological conditions {. Such X-rays are impractical in cases where the grid is made of precious or rare materials. For such cases, lattices are known in which the problems of strength and stability are solved by means of a separate reference node. Closest to the proposed invention is a flush, made of a mesh placed on a substrate, fastened in a frame and made of parallel wire elements connected to a tensioning device (2). However, the disadvantage of this peuje TKH is that the tension of the wire elements of the substrate is carried out independently of the change in the properties of the materials of which they are made. This means that the temperature range of application of such gratings is limited by the properties of the materials used, in particular the yield strength, and the modulus of elasticity. The aim of the invention is to expand the temperature limits of the use of the gratings by eliminating the indicated substrate deficiency. This goal is achieved by the fact that the wire supporting elements of the substrate are made in the form of helical spirals and the turns of the neighboring spirals are interconnected. FIG. 1 shows a partial image of the pre, lagging lattice, cross section; in fig. 2 is a schematic representation of a portion of the substrate. The lattice, for example, of a round form, consists of a catalytic grid J laid on the substrate 2, the supporting elements T1.1.1 3 of which are formed in the form of spirals from one or several, for example two, wires (see Fig. 2) and are placed in one plane parallel rows. The coils of neighboring spirals are interlinked with each other, for example, by the method of screwing one spiral 5 into another.
Концы опорных элементой 3 приварены к сегментам внутренней рамки 4. По биссектрисе угла каждого сегмента установлена шпилька 5, котора пропущена через отверстие 6 наружного сплошного кольца 7 и снабжена нат жной гайкой 8 дл предварительного нат жени . Каталитнческа сетка 1 удерживаетс на внутренней .рамке посредством пластин 9. В других частных случа х исполнени концы опорных элементов аодложки вместо приварки к |$ сегментам могут быть зажаты, укреплены наThe ends of the support element 3 are welded to the segments of the inner frame 4. In the bisector of the angle of each segment, a stud 5 is installed, which is passed through the hole 6 of the outer continuous ring 7 and is equipped with a tension nut 8 for pre-tensioning. Catalytic mesh 1 is held on the inner frame by means of plates 9. In other particular cases of execution, the ends of the supporting elements of the AOD, instead of welding to the segments, can be clamped, fixed on
крюках, клинь х, и.т. и. Материалы элементов выбирают в зависимости от температуры и химических условий работы, а предварительное нат жение подбирают или рассчитывают по известным зависимост м.20hooks, wedge x, it. and. The materials of the elements are chosen depending on the temperature and chemical working conditions, and the preliminary tension is selected or calculated according to known dependencies
Во врем работы температурные деформации подложки компенсируютс совместно за счет упругих свойств спиралей и материа; а, из которого они наготовлены.During operation, the thermal deformations of the substrate are jointly compensated for by the elastic properties of the spirals and the material; and from which they are prepared.
Подача газов через решетку и давление в аппарате не вли ет на состо ние подложки. Эффективность изобретени выражаетс повышением надежности работы в широком температурном диапазоне. Например, дл условийThe supply of gases through the lattice and the pressure in the apparatus does not affect the state of the substrate. The effectiveness of the invention is expressed in increasing the reliability of operation over a wide temperature range. For example, for conditions
окислени аммиака при соответствующем подборе материалов модуль упругости подложки может быть близким к 10, что определ ет низкие внутренние напр жени в материале при больших значенн х температурных деформацнй .oxidation of ammonia with an appropriate selection of materials, the modulus of elasticity of the substrate can be close to 10, which determines the low internal stresses in the material at high temperature thermal deformation.
