Abstract

Изобретение относитс к промышленности строительных материалов, преимущественно к теплообменным устройствам вращающихс печей при производстве цементного клинкера, позвол ет достичь повышение эффективности теплообмена и пылеулавливани . Циклон содержит цилин- дроконический корпус 1 с течкой 2, осевую выхлопную трубу 4 и тангенциальный входной патрубок 3, нижний торец выхлопной трубы заглушен, а в боковой поверхности выполнены отверсти , расположенные по касательной к внутренней поверхности выхлопной трубы, и имеют направление, обратное циркул ции пылегазовой смеси, в течке циклона в средней части установлена конусообразна диафрагма 6, имеюща угол раскрыти а 10-60&deg;, нижн полость которой соединена с верхней полостью и выхлопной трубой циклона двум обводными трубками 7,8. Верхний конец обводной трубки 7, соедин ющий нижнюю и верхнюю полости диафрагмы, расположен по ходу материала и на рассто нии не больше одного диаметра диафрагмы над ее нижним отверстием . 3 з.п. ф-лы, 2 ил.The invention relates to the building materials industry, primarily to heat exchangers of rotary kilns in the production of cement clinker, which makes it possible to achieve an increase in the efficiency of heat exchange and dedusting. The cyclone contains a cylindrical housing 1 with a chute 2, an axial exhaust pipe 4 and a tangential inlet 3, the lower end of the exhaust pipe is plugged, and in the side surface there are holes that are tangential to the inner surface of the exhaust pipe and have a reverse circulation dust and gas mixture, in the cyclone flow in the middle part there is a cone-shaped diaphragm 6, having an opening angle of 10-60 °, the lower cavity of which is connected to the upper cavity and the exhaust pipe of the cyclone by two circumferential pipes cuttings 7.8. The upper end of the bypass tube 7 connecting the lower and upper cavities of the diaphragm is located along the material and at a distance of not more than one diameter of the diaphragm above its lower opening. 3 hp f-ly, 2 ill.

Claims

Claim

1. Heat transfer cyclone containing a cylindrical conical housing with estrus, an axial exhaust pipe with openings on the wall, and a tangential inlet pipe, characterized in that, in order to increase the efficiency of heat exchange and dust collection, the lower end of the exhaust pipe is muffled, and the estrus is made with a conical diaphragm in the middle part and is equipped with bypass tubes connecting the lower part of the estrus with the cavity of the diaphragm and the exhaust pipe.

2. The cyclone according to claim 1, characterized in that the holes in the exhaust pipe are made tangential to the inner surface of the exhaust pipe in the direction opposite to the circulation of the dust and gas mixture in the cyclone.

3. The cyclone according to claim 1, characterized in that the opening angle of the conical diaphragm is 10-60 °.

4. The cyclone according to claim 1, characterized in that the upper end of the bypass tube connecting the lower cavity of the estrus with the cavity of the diaphragm is installed along the material and at a distance of not more than the diameter of the diaphragm above its lower hole.
