Description
(54) СЕКЦИЯ РЕКУПЕРАТИВНОГО ВОЗДУХОПОДОГРЕВАТЕЛЯ(54) SECTION OF RECOVERATIVE AIR HEATER
1one
Изобретение относитс к теплообменной технике и может быть использовано в тепловых установках.The invention relates to heat exchange technology and can be used in thermal installations.
Известны секции рекуперативного воздухоподогревател , содержащие установленный в газоходе пучок параллельных пр мых труб, конечные участки которых закреплены в газоходе 1.Regenerative air preheater sections are known that contain a bundle of parallel straight pipes installed in the duct, the end portions of which are fixed in the duct 1.
Недостатком указанной секции вл етс низка компенсаци температурных удлинений труб, что приводит к деформации и разрушению секции в процессе эксплуатацииThe disadvantage of this section is low compensation of the temperature lengthening of the pipes, which leads to the deformation and destruction of the section during operation.
Наиболее близкой к предлагаемой вл етс секци воздухоподогревател , содержаща установленный в газоходе пучок параллельных труб, конечные участки-которых закреплены в трубных досках и соединены наклонными средними участками, причем конечные участки каждой трубы, расположены с заданным смещением относительно оси газохода 2.Closest to the proposed is the section of the heater, which contains a bundle of parallel tubes installed in the duct, the end sections of which are fixed in tube plates and connected by inclined middle sections, with the end sections of each tube located at a given offset relative to the axis of the duct 2.
Известна секци имеет надежную компенсацию температурных удлинений труб, но ее недостатком вл етс сложность изготовлени , св занна с тем, что конечные участки труб расположены не перпендикул рноThe known section has a reliable compensation for the temperature lengthening of the pipes, but its disadvantage is the complexity of manufacturing, due to the fact that the end sections of the pipes are not perpendicular
оси газохода, что усложн ет конструкцию трубных досок.the axis of the flue, which complicates the design of tube plates.
Цель изобретени - упрощение изготовлени секции.The purpose of the invention is to simplify the manufacture of the section.
Дл достижени поставленной цели конечные участки труб пучка расположены перпендикул рно относительно оси газохода, а величина их взаимного смещени в направлении оси газохода составл ет не менее половины размера трубной доски.To achieve this goal, the end sections of the beam tubes are located perpendicularly relative to the axis of the duct, and their mutual displacement in the direction of the axis of the duct is at least half the size of the tube board.
На фиг. 1 показана предлагаема секци , FIG. 1 shows the proposed section,
10 разрез; на фиг. 2 - последовательность сборки секции.10 cut; in fig. 2 - section assembly sequence.
Секци содержит установленный в газоходе 1 пучок параллельных труб 2, конечные участки 3 и 4 которых закреплены в 15 трубных досках 5 и соединены йаклонными средними участками 6, причем конечные участки 3 и 4 каждой трубы 2 расположены со взаимным смещением не менее половины размера трубной доски 5 в направлении оси газохода 1 и перпендикул рно относи ° тельно этой оси. К трубным доскам 5 присоединены подвод щие и отвод щие воздущные камеры 7 и 8.The section contains a bundle of parallel pipes 2 installed in the gas duct 1, the end sections 3 and 4 of which are fixed in 15 tube plates 5 and connected by means of the inclined middle sections 6, with the end sections 3 and 4 of each tube 2 arranged with a mutual displacement of at least half the size of the tube plate 5 in the direction of the axis of the duct 1 and perpendicularly relative to this axis. Inlet and outlet air chambers 7 and 8 are connected to the tube plates 5.
