АППАРАТАAPPARATUS

Изобретение относитс к конструктивным элементам теплообменных аппаратов.The invention relates to structural elements of heat exchangers.
По основному .авт. св. № 568834 известна опорна перегородка дл теплообменного аппарата, выполненна в виде составной решетки с разрезными зажимными втулками установленными на трубы в непосредственном контакте одна с другой и поджатыми по периферии пучка при помощи нажимных элементов, имеющих сегментную форму ij.On the main. Avt. St. No. 568834 is a known support partition for a heat exchanger, made in the form of a composite lattice with split clamping sleeves mounted on the pipes in direct contact with one another and tucked around the periphery of the beam with the help of pressure elements having a segment shape ij.
Однако известна опорна перегородка, хот и обеспечивает надежное закреппе- ние труб, однако ей присущ недостаток, а именно: в процессе сварки опорной перегородки с трубным пучком кажда теп- лообменна труба проталкиваетс в отверстие втулки, В результате поверхность труб может повреждатьс , а во-вторыл в местах контакта поверхностей втулок и труб имеющие место щелевые зазоры, вл ютс застойной зоной, иэ-за отсутстви движени теплоносител в них, вследствие ик малой величины, а такжаHowever, the support partition is known, although it provides reliable fixing of the pipes, but it has a drawback, namely: during the welding process of the support partition with the tube bundle, each heat exchange tube is pushed into the sleeve opening, as a result, the surface of the tubes can be damaged and The second, at the points of contact of the surfaces of the sleeves and pipes, the gap gaps that have taken place are a stagnant zone, and due to the absence of coolant movement in them, due to their small size, and
зоной отложени накипи и продуктов кор розии, привод щих к сокращению срока эксплуатации труС.the area of scale and corrosion products deposition, resulting in a shortened life of the pipe.
Шль изобретени - повышение надежности теплообменного аппарата, вс едет вне устранени недостатков, присущих известной опорной перегородки.The invention is an increase in the reliability of the heat exchanger, it entirely goes beyond eliminating the disadvantages inherent in the known supporting partition.
Указанна цепь достигаетс тем, что втулки снабжены выступами, расположенными по ее периметру с заданным шагом и контактирующими с наружными стенками труб с образованием зазоров дл циркул ции теплоносител .This circuit is achieved by the fact that the bushings are provided with protrusions located along its perimeter at a predetermined pitch and in contact with the outer walls of the pipes with the formation of gaps for the circulation of the heat transfer medium.
На фиг. 1 изображена опорна перегородка с укрепленными теплообменными трубами, поперечный разрез; на фиг. 2 разрез А-А на фиг. 1 ; на фиг. 3 - разрез Б-Б на фиг. 2; на фиг. 4 - вид Г на фиг. 3j на фиг. 5 - вариант выполнени вЬютупа во втулке; на фиг. 6 - разрез В-В на фиг. 5.FIG. 1 shows a support partition with reinforced heat exchange tubes, a cross section; in fig. 2, section A-A in FIG. one ; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a view of FIG. 3j in FIG. 5 shows an embodiment of a sleeve in a sleeve; in fig. 6 is a sectional view BB in FIG. five.
