Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see Figure 1~4 , in the embodiment of the present invention, a new type of heat exchange unit is mainly composed of a heat exchanger 1 and a desuperheater 6. The heat exchanger 1 is provided with a U-shaped heat exchange pipe 11, and the position above the desuperheater 6 A desuperheater steam inlet pipe 7 and a cold water inlet and outlet pipe 8 are provided, wherein high-temperature steam is sent into the desuperheater 6 from the desuperheater steam ...

Abstract

The invention discloses a novel heat exchanging unit, which is mainly composed of a heat exchanger and an attemperator. An attemperator steam inlet tube and a cold water outlet and inlet tube are arranged on the upper part of the attemperator, and a heat exchanger water inlet, a heat exchanger steam inlet, a condensate water outlet and a heat exchanger water return opening are formed in the heat exchanger. High-temperature steam is subjected to heat exchanging in the attemperator firstly, at the moment, the temperature of the high-temperature steam is decreased correspondingly, then the high-temperature steam enters the heat exchanger to be subjected to heat exchanging, at the moment, the temperature of the steam entering the heat exchanger is effectively decreased, in this way, damage toa rubber pad is avoided, and thus the requirement for temperature resistance of the rubber pad is lowered.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a novel heat exchange unit. Background technique [0002] The heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through the plates. The heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. In the case of the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third of that of the tube heat exchanger, and the heat recovery rate can be as high as 90%. [0003] The plates in the existing heat exchanger are sealed by high temperature resistant rubb...
