Description

Применение рекуператоров или воздухоподогревателей дл  испольЗовани  тепла отход щих газов металлургических печей, а также регенеративные подогреватели, предназначенные дл  нагрева воздуха и газа, известны.The use of heat exchangers or air preheaters for using the heat of the exhaust gases of metallurgical furnaces, as well as regenerative preheaters for heating air and gas, are known.

Предлагаемый рекуператор отличаетс  от них тем, что, с целью упрощени  изготовлени  и эксплуатации, каждый его элемент выполнен из двух труб, из которых одна помещена внутри другой. В межтрубное пространство пропускаетс  воздух, а по внутренней трубе - газ, что позвол ет одновременно подогревать газ и воздух.The proposed heat exchanger differs from them in that, in order to simplify manufacture and operation, each of its elements is made of two tubes, of which one is placed inside the other. Air flows through the annular space, and gas passes through the inner pipe, which allows the gas and air to be preheated at the same time.

На фиг. 1 изображен рекуператор в продольном разрезе по А-А на фиг. 3; на фиг. 2 - то же, по Б-Б на фиг. 3; на фиг. 3 - то же, в поперечном разрезе по В-В на фиг. 1; на фиг. 4 - узел С.FIG. 1 shows a heat exchanger in longitudinal section along A-A in FIG. 3; in fig. 2 is the same according to BB in FIG. 3; in fig. 3 is the same in cross section along BB in FIG. one; in fig. 4 - node C.

Рекуператор дл  упрощени  изготовлени  и эксплуатации выполнен из элементов, представл ющих собой две трубы 1 и 2, из которых труба 2 помещена внутри трубы 1. Межтрубное пространство слулшт дл  движени  воздуха, а внутренн   труба 2 - дл  движени  газа.The recuperator, to simplify production and operation, is made of elements consisting of two pipes 1 and 2, of which pipe 2 is placed inside pipe 1. Intertubular space is for moving air, and internal pipe 2 for moving gas.

Наружные трубы 1 верхним и нижним концами присоединены к горизонтальным коробчатым ллитам 3, которые с донышком 4 образуют нижний воздушный коллектор 5, а с плитой 6 - верхний воздушный коллектор 7. Внутренние трубы 2 нижними концами соединены с горизонтальными трубами 8, образующими нижний газовый коллектор. Верхние концы внутренних труб вварены в плиту 6, раздел ющую воздушный коллектор 7 и верхний газовый коллектор 8. Отход щие после печей продукты горени  на своем пути смывают наружные поверхности труб /, по которым движетс  холодный воздух; одновременно по внутренним трубам 2 движетс  холодный газ. По мере прохождени  по трубам воздух и газ постепенно подогреваютс , после чего отвод тс  из рекуператра -по назначению.The outer pipes 1 are attached to the upper and lower ends of the horizontal box-shaped llitas 3, which with the bottom 4 form the lower air manifold 5, and with the slab 6 - the upper air manifold 7. The inner pipes 2 lower ends are connected with horizontal pipes 8 forming the lower gas manifold. The upper ends of the inner tubes are welded into the plate 6, which separates the air manifold 7 and the upper gas manifold 8. The waste products after the furnaces on their way wash the outer surfaces of the tubes / along which cold air moves; at the same time cold gas flows through the internal pipes 2. As they pass through the pipes, air and gas are gradually heated, after which they are discharged from the recuperator according to their intended purpose.

№ 86808- 2 -No. 86808-2 -

Таким образом, подогрев воздуха осуществл етс  благодар  теплопередаче стенок наружной трубы /, а подогрев газа - за счет лучеиспускани  стенок внешней трубы 1 и теплопередачи воздуха и стенок внутренней трубы 2.Thus, the air is heated due to the heat transfer of the walls of the outer pipe /, and the heating of the gas due to the radiation of the walls of the outer pipe 1 and the heat transfer of the air and the walls of the inner pipe 2.

Описываемый рекуператор может быть установлен в боровах больших и малых печей.The described heat exchanger can be installed in the hogs of large and small furnaces.

Предмет изобретени Subject invention

Рекуператор дл  одновременного подогрева воздуха и газа, устанавливаемый в боровах металлургических печей, работаюш;их на бедном газе, отличающийс  тем, что, с целью упрощени  изготовлени  и эксплуатации, элементы рекуператора выполнены в виде обогреваемых снаружи труб, в которых помещены другие трубы так, что мел трубное пространство их служит дл  движени  воздуха, а центральна  труба дл  движени  газа.A recuperator for simultaneous heating of air and gas, installed in the hogs of metallurgical furnaces, works on a lean gas, characterized in that, in order to simplify production and operation, the elements of the heat exchanger are made in the form of tubes that are heated outside; their chalk tube space serves to move air, and the central tube to move gas.
