VERTICAL STRAIGHT-TUBE COUNTERCURRENT CONDENSER Russian patent published in 2018 - IPC B01D1/06 F28B1/02 F28B9/10 F28D7/10 

FIELD: heating equipment.

SUBSTANCE: invention relates to the field of heat engineering and can be used in capacitors. Vertical straight shell-tube countercurrent condenser, in which the condensing vapor flows through the intertubular space of the condenser, and the cooling water in the pipe space is two-way both in the shell space and in the tube space, the heating surface of the first stroke in the annulus is formed from heating surface tubes (9) in vapor space (14) of this stroke, attached at their upper ends to upper tube plate (5) and the lower ends to lower tube plate (7), through these pipes the cooling water of the second course of the tube space flows, wherein the heating surface of the second annulus of the annular space is formed by heating surface tubes (10) in vapor space (15) of the second stroke, attached at their upper ends to upper tube plate (5) and the lower ends to the other lower tube plate, through these pipes the cooling water of the first course of the tube space flows, thus, said vapor spaces (14, 15) are connected by means of hole (12) between upper end (11) of partition wall (4, 50) separating the shell space and upper tube plate (5), the direction of the steam flow in vapor space (14) of the first stroke of the annular space is directed upwards, and in other vapor space (15) is directed downward, the direction of the flow of cooling water in pipes (9 and 10) of the heating surface of both strokes is countercurrent to the flow of steam flowing outside the said pipes.

EFFECT: obtaining the maximum amount of pure condensate for reuse.

11 cl, 6 dwg
