What are the advantages and disadvantages of graphite heat exchanger blocks and

The round block graphite heat exchanger and the tubular graphite heat exchanger are mainly used in chlor-alkali chemical industry, petrochemical industry, fluoride salt, titanium dioxide, zirconium industry, chloroacetic acid, chlorinated paraffin, monocrystalline silicon fluorine chemical industry and other production industries. The main differences are as follows:

The circular block hole graphite heat exchanger is advanced in technology. It is composed of cylindrical graphite blocks impregnated by a special process, graphite heads and sealing gaskets in between, through metal cover plates, tie rods and springs. The heat main body has the advantages of high structural strength, strong temperature and pressure resistance, good impact resistance, high volume utilization, high heat transfer effect, long service life and easy maintenance. If there is leakage, the heat exchange block can be replaced without affecting Heat exchange area, strong temperature and pressure resistance, excellent impact ability, small size, high utilization rate, easy maintenance, can be used as graphite evaporator, graphite heater, graphite cooler, graphite condenser, reboiler, etc. , especially the effect of heater, reboiler and condenser is more ideal.

The tubular graphite heat exchanger has the advantages of easy inspection of all seals, reduced pressure, large product specifications, and low price. The limit temperature of the tubular graphite heat exchanger is generally 130 degrees. The round block hole graphite heat exchanger can reach 165 degrees. If there is leakage, the tubular graphite heat exchanger is mostly repaired by blocking the pipe. If the blocked pipe exceeds a certain number, it will affect the heat exchange area and effect.
