Изобретение относитс к кожухотрубным теплообменникам и может быть использовано в различных отрасл х народного хоз йства .The invention relates to shell-and-tube heat exchangers and can be used in various sectors of the national economy.
Целью изобретени вл етс интенсификаци теплообмена и уменьшение металлоемкости теплообменника.The aim of the invention is to intensify heat exchange and reduce the metal intensity of the heat exchanger.
На фиг. 1 изображен пучок теплооб- менных труб предлагаемого теплообменника; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - сечение Б-Б на фиг. 1.FIG. 1 shows a bundle of heat exchange tubes of the proposed heat exchanger; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.
Кожухотрубный теплообменник содержит винтообразно закрученные теплообменные трубы 1 овального профил , закрепленные пр мыми круглыми концами в трубных досках 2 и установленные одна относительно )5 другой с касанием по максимальному размеру овала. Трубы 1 состо т из участков 3 и 4 длиной (5-7) d, имеющих противоположное направление закрутки и разделенных пр мыми участками 5 длиной (1-2)d, где d - максмене направлени закрутки труб происход т разрушение пристенного сло жидкости на трубах и выравнивание параметров потока по сечению трубного пучка. При этом осуществл етс теплообмен со средой, протекающей по трубам 1, через стенки труб. Затем теплообменивающа среда выводитс из т-сплообменника.The shell-and-tube heat exchanger contains helically twisted heat-exchange tubes 1 of the oval profile, fixed with straight round ends in tube plates 2 and installed one relative to the other 5 with a touch on the maximum size of the oval. The pipes 1 consist of sections 3 and 4 of length (5-7) d, having the opposite direction of twist and separated by straight sections 5 of length (1-2) d, where d is the max change in the direction of twisting of the pipes; and alignment of flow parameters over the cross section of the tube bundle. This involves heat exchange with the medium flowing through the pipes 1 through the walls of the pipes. The heat exchanging medium is then withdrawn from the t-heat exchanger.
При прот женности закрученных участков (5-7)d теплообмен интенсифицируетс благодар услови м течени и теплоотдачи на начальных участках по всей длине теплообменника. Нар ду с интенсификацией теплообмена снижаютс масса и металлоемкость теплообменника.With the length of the twisted sections (5-7) d, heat transfer is intensified due to the conditions of flow and heat transfer in the initial sections along the entire length of the heat exchanger. Along with the intensification of heat exchange, the mass and metal intensity of the heat exchanger are reduced.
