Description
Изобретение относитс к теплооб- менной аппаратуре и может быть использовано в энергетической промышленности .The invention relates to heat exchange apparatus and can be used in the energy industry.
Целью изобретени вл етс инфор- наци теплообмена при горизонтальном расположении аппарата.The aim of the invention is to provide heat transfer information with a horizontal arrangement of the apparatus.
На фиг.1 схематично изображен предлагаемый аппарат, на фиг. 2 - узел креплени козырька над трубой j; на фиг.З - трубна доска.с различными вариантами выполнени козырьков,1 schematically shows the proposed apparatus, FIG. 2 - visor attachment unit over pipe j; Fig. 3 shows a pipe board. With various embodiments of peaks,
Теплообменный аппарат содержит пучок теплообменных труб 1, закрепленных в трубных досках 2, раздающий коллектор 3 со встроенным в него перераспределительным устройством 4 дл газожидкостного теплоносител , подаваемого в трубы 1, выполненным в виде системы козырьков 5 с отогнутыми вниз боковыми кромками б. Трубна доска 2 со стороны раздающего коллектора 3 может быть снабжена диском 7 с отвер- сТ-и ми под трубы 1 и закрепленным на нем перераспределительным устройством |4. Козырьки 5 могут быть выполнены с выступами 8 и впадинами 9, последние из которых имеют в нижней части перфорацию 10, и могут быть .выпол- нены с различной длиной, уменьшающейс по высоте аппарата снизу вверх.The heat exchanger contains a bundle of heat exchange tubes 1 fixed in tube plates 2, distributing the collector 3 with the redistribution device 4 for the gas-liquid heat transfer fluid embedded in it, made in the form of a system of canopies 5 with the side edges bent downwards b. The pipe board 2 on the side of the distributing collector 3 can be equipped with a disk 7 with holes for pipes 1 and a redistribution device | 4 fixed on it. The peaks 5 can be made with protrusions 8 and depressions 9, the latter of which have a perforation 10 in the lower part, and can be made with different lengths, decreasing in height from the bottom upwards.
Теплообменный аппарат работает следующим образом.The heat exchanger operates as follows.
Охлаждаема среда, например нефCooling medium, such as nave
т ной газ, содержащий капли жидкости 35 вани ) равномернее, чем в случае вы (масло, конденсат или вводимый в газовый поток с помощью форсунки ингибитор гидратообразовани , например гликоль), поступает через патрубок внутрь раздающего коллектора 3. Далее газ поступает внутрь теплообменных труб 1, закрепленных в трубной доске 2, где он охлаждаетс потоком охлаждающей среды, проход щей снаружи трубного пучка, снизу вверх. Содержаща с в охлаждаемом потоке жидкость , например ингибитор гидратообразовани (гликоль), частично уно- ситс потоком газа внутрь теплообменных труб 1 в виде капель. Если скорость витани капель жидкости не позвол ет им осаждатьс на поверхности трубной доски, то жидкость частично выноситс потоком газа внутрь теплообменных труб 1 и предотвращает гидратообразование в них. Основна же масса жидкости оседает на трубной доске 2 и стекает ho ее поверхности на дно раздающего коллектора 3, пеполнени козырьков одного профил . Таким образом, за счет выполнени козырьков разного профил создаетс дополнительный эффект, улучшающий рабо40 ту теплообменника.This gas containing liquid droplets 35 is more uniform than in the case of you (oil, condensate or a hydrate formation inhibitor, such as glycol) introduced into the gas stream by means of a nozzle, then flows through the inside of the distributing collector 3 fixed in tube plate 2 where it is cooled by a flow of cooling medium passing outside the tube bundle from bottom to top. The liquid contained in the cooled stream, such as a hydrate inhibitor (glycol), is partially carried by the gas stream into the heat exchange tubes 1 in the form of droplets. If the soaring speed of the liquid droplets does not allow them to settle on the surface of the tube plate, the liquid is partially carried by the gas flow inside the heat exchange tubes 1 and prevents hydrate formation in them. The main mass of the liquid settles on the tube plate 2 and flows its surface to the bottom of the dispensing manifold 3, filling the visors of one profile. Thus, by making the visors of a different profile create an additional effect that improves the operation of the heat exchanger.
При избытке (ингибитора гидратообразовани ), неувлеченной в трубы трубного пучка, она выводитс через штуцер, размещенный в доннойWith an excess (hydrate inhibitor) not drawn into the tubes of the tube bundle, it is discharged through a fitting placed in the bottom
45 части раздающего коллектора 3.45 parts of the distributing collector 3.
Наличие на трубной доске 2 диска 7 с закрепленным на нем перераспределительным устройством 4 упрощает мон- таж и повышает надежность работы.The presence on disk 2 of a tube 7 with a fixed on it redistributive device 4 simplifies installation and increases reliability.
50 Диск 7 может быть выполнен из полиуретана или из напыленного на трубную доску 2 металла.50 The disk 7 can be made of polyurethane or of metal deposited on a tube plate 2.
