Abstract

Изобретение относится к теплотехнике и может быть использовано в теплообменных аппаратах, например, в производстве карбамида. В теплообменном аппарате, содержащем по крайней мере одну внутреннюю теплообменную трубу с турбулизатором, турбулизатор расположен вблизи входного отверстия теплообменной трубы и представляет собой цилиндрический корпус с отверстиями для входа и выхода сред, внутри которого по ходу движения среды последовательно расположены струеформирующая насадка и консольно закрепленная в цилиндрическом корпусе навстречу движению среды пластина-резонатор с двумя выступами, дугообразно загнутыми в противоположные стороны таким образом, что они вплотную примыкают к внутренней поверхности цилиндрического корпуса, образуя крепление пластины. Технический результат - повышение эффективности работы теплообменника.The invention relates to heat engineering and can be used in heat exchangers, for example, in the production of urea. In a heat exchanger containing at least one internal heat exchanger tube with a turbulizer, the turbulizer is located near the inlet of the heat exchange tube and is a cylindrical body with openings for the inlet and outlet of media, inside of which a jet-forming nozzle is sequentially located in the direction of movement of the medium and cantilevered in a cylindrical the housing towards the movement of the medium is a plate-resonator with two protrusions, arcuately bent in opposite directions in such a way that they closely adjoin the inner surface of the cylindrical body, forming a plate mount. The technical result is to increase the efficiency of the heat exchanger.
