High-stability graphite heat exchanger

Abstract

The invention discloses a high-stability graphite heat exchanger comprising a graphite heat exchanger body. The end of the graphite heat exchanger body is fixedly provided with a connection protectiveplate. The bottom end of the graphite heat exchanger body is fixedly provided with supporting columns. Heat transfer pipes are evenly distributed in the graphite heat exchanger body. The gap generated among every four heat transfer pipes is filled with polyurethane foam. The surface of the top end of the graphite heat exchanger body is provided with a first connection opening. According to the high-stability graphite heat exchanger, the intervals among the heat transfer pipes is effectively filled with the polyurethane foam, heat emitted by the heat transfer pipes is stored, so that energy loss caused by emission is avoided, and therefore the use performance is improved when the heat transfer pipes conduct heat exchange. Meanwhile, due to the features of the polyurethane foam, the heat transfer pipes can be protected to a certain extent, and the cracking possibility of the heat transfer pipes is lowered.

Description

technical field [0001] The invention belongs to the technical field of graphite heat exchangers, in particular to a graphite heat exchanger with high stability. Background technique [0002] Graphite heat exchangers are heat exchangers made of graphite for heat transfer components. The graphite used to manufacture heat exchangers should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. The cost of graphite heat exchangers High, large volume, it is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, such as processing benzoyl chloride, trichlorotoluene and benzophenone, and can also be used in chlor-alkali chemical industry, petroleum Chemical industry, fluoride salt, titanium dioxide, zirconium industry, chloroacetic acid, chlorinated paraffin, single crystal silicon fluorine chemical industry and other production industries. [0003] There are still so...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of graphite heat exchanger with high stability, to solve the above-mentioned background technology because graphite heat exchanger generally is when two kinds of different media pass through each other in graphite heat exchanger in use. , the high-temperature medium continuously transfers heat to the graphite heat exchanger, and the low-temperature medium continuously obtains heat from the heat exchanger, but when converting, the built-in pipe contact surface is small, and there is a large gap at the same time, resulting in poor heat transfer effect , thereby affecting work efficiency, and at the same time, when connecting with external pipelines, it is generally necessary to fix them with bolts, but there are great difficulties in later maintenance or cleaning, which greatly reduces the problem of work efficiency
