Description

Reducing graphite heat exchanger

Technical Field

The utility model relates to a graphite heat exchanger technical field especially relates to a reducing graphite heat exchanger.

Background

The graphite heat exchanger is a heat exchanger made of graphite for a heat transfer assembly, and the working principle of the graphite heat exchanger is as follows: according to the acid corrosion resistance and good heat conduction performance of graphite, a flow guide device is made of graphite, when two media pass through each other, the high-temperature medium continuously transmits heat to the graphite heat exchanger, and the low-temperature medium continuously obtains heat from the heat exchanger, so that heat exchange is realized. According to the characteristics of graphite, the graphite heat exchanger is increasingly widely applied to the industries such as cold rolling and pickling lines, chemical industry, petroleum, pesticide and the like. The traditional graphite heat exchanger can be divided into 3 types of block hole type, shell and tube type and plate type according to the structure. Block hole type: is assembled by a plurality of block-shaped graphite components with holes. Shell-and-tube type: the shell-and-tube heat exchanger plays an important role in the graphite heat exchanger and is divided into a fixed type and a floating head type according to the structure. The block-hole type and the shell-and-tube type have good and bad heat exchange performance, like the block-hole type, the block-hole type heat exchange plate has the advantages of high structural strength and safe heat exchange, and has the defects that a large number of block-hole type heat exchange blocks are needed to be spliced to form a heat exchange core body, the graphite usage amount is large, the cost is high, the interval between a cooling medium channel and a high-temperature acid liquid channel is large, and the cooling effect is not good; the shell-and-tube type graphite tube has the advantages that the graphite tube is directly contacted with a cooling medium, the heat exchange area is large, the heat exchange effect is good, the graphite usage amount is small, and the defects that the structural strength is low and the graphite tube is easy to damage are overcome.
