Description

Изобретение относитс  к теплотехнике и может быть использовано ал  подогрева больших объемов газа под давлением.The invention relates to heat engineering and can be used to preheat large volumes of gas under pressure.

Известны теплообменники дл  подогрева природного газа, содержащие корпус с размешенной в нем жаровой трубой с горелкой И .Heat exchangers are known for preheating natural gas, comprising a housing with a flame tube with an I burner placed therein.

Недостаток такого теплообменника заключаетс  в том, что нагрев газа происходит при контакте через стенку продуктов сгорани  и нагреваемого газа, в виду чего степень взрывоопасности недопустимо велика .The disadvantage of such a heat exchanger is that the gas is heated by contact through the wall of the combustion products and the heated gas, due to which the degree of explosive danger is unacceptably high.

Наиболее близким решением из известных к предложенному  вл етс  теплообменник , содержащий заполне1гный промежуточны теплоносителем корпус с размещенным в нем шахматнь1м пучком горизонтальных труб, подключенных к источнику нагреваемо среды, и нагреватель 2 .The closest solution known to the proposed is a heat exchanger containing a housing filled with coolant intermediate with a chessboard bundle of horizontal pipes placed in it, connected to a source of heated medium, and a heater 2.

Недостатком известного теплообменника  вл етс  то, что интенсивность теплообмена между нагреваемым газом и промежуточньпу; теплоносителем недостаточно велика , так как происходит в услови х свободной Конвекции.A disadvantage of the known heat exchanger is that the intensity of heat exchange between the heated gas and the intermediate one; the coolant is not large enough, as occurs under conditions of free convection.

Цель изобретени  - интенсификаци  теплообмена .The purpose of the invention is to intensify heat transfer.

Это достигаетс  тем, что трубы нижнего р да пучка снабжены продольными ребрами , перекрывающими в свету вертикальный зазор между трубами и напраЕ ленными в сторону смежных труб соседнего р да.This is achieved by the fact that the tubes of the lower row of the beam are provided with longitudinal ribs, covering the vertical gap between the tubes and facing toward the adjacent tubes of the adjacent row.

На чертеже изображен теплообменник, поперечный разрез.The drawing shows a heat exchanger, cross section.

Он имеет заполненный промежуточным теплоносителем корпус 1 с размещеннь1М в нем шахматным пучком 2 горизонтальных труб 3 и нагреватель 4, выполненный в виде газовьгх излучателей 5, Трубы 3 нижнего р да пучка 2 снабжены продольньтми ребрами 6.It has a housing 1 filled with an intermediate heat carrier with a staggered bundle of 2 horizontal pipes 3 and a heater 4 in the form of a gas radiator 5, the pipes 3 of the lower row of the beam 2 are equipped with longitudinal ribs 6.

Теплообменник работает следующим образом .The heat exchanger operates as follows.

Газовьте излучатели Я нагревают дно корпуса 1 теплообменника. Промежуточный теплоноситель, заполн ющий корпус. начинает кипеть. Пузырьки пара поанимаютс .Gas emitters I heat the bottom of the body 1 of the heat exchanger. Intermediate heat carrier filling the case. starts to boil. Bubbles of steam are absorbed.

вверх и оседают на нижней стороне труб 3 и продольных .ребрах 6. Лопа сь, пуэь1рьки пара отдают скрытую теплоту парообразовани  через поверхность труб 3 нагреваемому газу. Кипение происходит в уэком пространстве между дном корпуса 1 и трубами 3 пучка 2, На свободной поверхности промежуточного теплоносител  кипени  не происходит.upward and settle on the lower side of the pipes 3 and the longitudinal fringes 6. When bursting, steam pushers give up the latent heat of vaporization through the surface of the pipes 3 to the heated gas. Boiling occurs in the space between the bottom of the housing 1 and the tubes 3 of the beam 2. There is no boiling on the free surface of the intermediate heat transfer medium.

Благодар  такому вьтолнеЕ1ию теплообме ника теплоотдача трубам повышаетс , так как осуществл етс  наиболее эффективным методом - за счет пароконденсации.Due to this heat transfer efficiency, heat transfer to the pipes is increased, since it is carried out by the most efficient method - due to steam condensation.
