HEAT EXCHANGER FOR ATOMISING DRIER Russian patent published in 2013 - IPC F26B9/06 F26B3/12 F28D7/00 

Abstract RU 2484398 C1

FIELD: heating.

SUBSTANCE: in a heat exchanger for an atomising drier, which includes a furnace, a drier housing with an atomiser, heat exchange tubes, according to the proposed invention, the heat exchanger is made in the form of a longitudinally finned tube and a finned tube connected to it, which is located in the furnace mixing chamber; at that, when the tube leaves the furnace, it passes into the shell and tube heat exchanger, the upper part of which consists of a housing in the form of three inclined tubes (15 degrees) leaving the tube, which are changed over to horizontal tubes, on each end of which one rosette is located, and each rosette includes seven tubes of the same diameter; at that, the housing walls are heat insulated with heat insulating material, for example Penofol, and the housing has three inlet and outlet branch pipes of the heated solution and a branch pipe for the tank emptying; at that, the unit is equipped with a pressure gauge, a safety valve and a heat carrier filling valve and has an excess pressure compensation line for heat carrier filling at the operating unit, which is equipped with the valve; besides, in the unit there is a return line of the circulating circuit and an expansion tank with a branch pipe, and the drier atomiser includes a hollow housing, which consists of a cylindrical part with external thread for connection to a nozzle of a liquid supplying distributing pipeline, a conical transient part and a cylindrical part with large size of diametrical section, and with internal threaded surface, and coaxially to the housing, in its lower part there fixed is a nozzle formed with cylindrical surface with external thread interacting with cylindrical part of the housing; at that, cylindrical surface of the nozzle is changed over to a conical surface and ends with an end blind partition wall perpendicular to the housing axis, with an orifice in its centre, which is axisymmetrical to the nozzle and consists of cylindrical and conical orifice holes connected in series; at that, larger diameter of conical hole is located on the blind partition wall of the nozzle; at that, the housing and the nozzle form three internal cylindrical chambers, which are coaxial to each other, and on the nozzle, on the side opposite to liquid supply, there is an additional row of orifices, which are formed at least with three pairs of mutually perpendicular vertical channels for passage of liquid and horizontal channels, which are crossed on a conical side surface of the nozzle and form outlet holes of each of the orifices; at that, pair channels are located at a right angle to each other in longitudinal planes of the housing, and conical side surface of the nozzle is made at angle to the top, which is equal to 90°.

EFFECT: increasing efficiency and economy of the heat exchanger operation and increasing production capacity of the drier.
