Description
Изобретение относитс к котлостроекию и может быть использовано в дымовых трубах дл котла.The invention relates to boiler building and can be used in chimneys for a boiler.
Целью изобретени вл етс стабилизаци потока дымовых газов и снижение уровн шума.The aim of the invention is to stabilize the flue gas flow and reduce the noise level.
На фиг. 1 изображена труба, продольный разрез (разрез Б-Б на фиг. 2); на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows a pipe, a longitudinal section (section BB in FIG. 2); in fig. 2 is a section A-A in FIG. one.
Дымова труба, включающа несущий 1 и газоотвод щие стволы 2, разделенные воздущным зазором 3, снабжена перегородками 4, установленными в ее воздушном зазоре 3 верхней части, образующими замкнутую камеру 5 вокруг газоотвод щих стволов 2, причем газоотвод щие стволы 2 выполнены с отверсти ми 6, соедин ющими стволы 2 с камерой 5.A flue pipe, comprising carrier 1 and gas exhausting trunks 2, separated by an air gap 3, is provided with partitions 4 installed in its upper air gap 3, forming a closed chamber 5 around the gas exhausting trunks 2, and the gas exhausting trunks 2 are made with holes 6 connecting the trunks 2 with the camera 5.
Труба работает следующим образом.The pipe works as follows.
Уход щие газы имеют разную скорость в газоотвод щих стволах 2 при неравномерThe flue gases have different speeds in the flue 2, with uneven
ной нагрузке подключенных парогенераторов . Отверсти 6, выполненные в верхней части газоотвод щих стволов 2 и объединенные камерой 5, выравнивают давление во всех газоотвод щих стволах, в результате чего предлагаема труба по сравнению с известными обеспечивает снижение щума и стабилизацию течени в газоотвод щих стволах.Noah load connected steam generators. The openings 6, made in the upper part of the evacuation barrels 2 and connected by the chamber 5, equalize the pressure in all the evacuation barrels, as a result of which the proposed pipe, as compared to the known ones, reduces shum and stabilizes the flow in the gas venting.
Расположение отверстий в верхней части газоотвод щего ствола и соединение их с камерой позвол ет ликвидировать свист, возникающий при работе стволов с различной нагрузкой. Отверсти выравнивают давление во всех стволах, что одновременно с ликвидацией свиста стабилизирует течение в газоотвод щих стволах. Расположение отверстий, объединенных камерой в другом месте, например в нижней части трубы, приводит к ухудшению т ги, что экономически невыгодно.The arrangement of the holes in the upper part of the gas exhaust trunk and their connection with the chamber makes it possible to eliminate the whistling that occurs when the barrels operate with different loads. The holes equalize the pressure in all trunks, which simultaneously with the elimination of the whistle, stabilizes the flow in the gas exhaust trunks. The location of the holes, connected by a camera in another place, for example, at the bottom of the pipe, leads to a deterioration of traction, which is economically disadvantageous.
