Abstract: Использование: для экспериментальной проверки динамической устойчивости рычажных систем. Сущность изобретения: параметрические колебания рычажной системы возбуждаются с помощью газодинамического источника возмущающей силы, имеющей периодическую составляющую. Источник состоит из выхлопной трубы с решетками для выравнивания потока газа и подключенных к ней газоподводящих каналов с соплами на входе трубы. Пульсация потока газа может быть обеспечена выбором соответствующих геометрических параметров трубы или за счет оснащения одного из каналов средствами для обеспечения импульсного режима работы сопла. Параметры рычажной системы могут регулироваться с помощью передвижных по длине ее звеньев масс, фиксируемых в любой требуемой точке звена. На свободном конце близлежащего к источнику звена рычажной системы установлена сферическая преграда. Звенья соединены между собой упругими шарнирами. Первое звено уравновешено относительно его шарнирной опоры двумя упругими связями, одна из которых выполнена в виде пружины, а в качестве второй использован датчик силы. При использовании изобретения возможно определение зон динамической устойчивости системы в зависимости от параметров возмущающей силы и геометрических и физических параметров рычажной системы. 1 ил.

Abstract: FIELD: petroleum refining industry for cleaning off-gases discharged during pouring bitumen at petroleum processing enterprises. SUBSTANCE: off-gases resulting from bitumen pouring operation are subjected to cleaning by two-step process. In the first step, off-gases are passed through hydrocarbon fraction which boils down within temperature range 220-350 C, followed by second cleaning step in which off-gases are passed through biofilter containing microorganisms and irrigated with aqueous solution of nutrient salts at 15-35 C for 1-2 min at flow velocity 0.5-1.2 ms. Nutrient liquid circulates in direction from biofilter bottom upwards, liquid flow being replenished with circulating water in the amount sufficient to maintain prescribed liquid level 0.5-0.7 m in biofilter. Gas cleaning is effected using combination of active strains of microorganisms belonging to genera Arthrobacter, Mycobacterium, Pseudomonas of filamentous iron- and sulphur-containing bacteria taken in ratio 0.7:0.15:0.1:0.05. These microorganisms effect cleaning of off-gases simultaneously from organic matter, nitric oxides, sulphur oxides, carbon oxides and hydrogen sulfide. Proposed biofilter represents hollow shell filled with plurality of wire supports coated with sectionalized fibrous layers adapted to carry bacteria. Lower part of shell additionally houses rigidly attached horizontal vessel and gas supply main in the form of perforated tube. Wire sections are 1 m high and their diameter is by 4-6 m smaller than biofilter diameter. EFFECT: higher efficiency. 5 cl, 3 dwg, 1 tbl, 13 ex
