Round blockGraphite heat exchangerAnd tube graphite heat exchangers are mainly used in the production industries of chlor-alkali chemical industry, petrochemical industry, fluoride salt, titanium dioxide, zirconium industry, chloroacetic acid, chlorinated paraffin, monocrystalline silicon fluoride, etc. The main differences between the two are as follows:
The round-hole type graphite heat exchanger has advanced technology. It consists of a cylindrical graphite block impregnated by a special process, a graphite head and a sealing gasket in between, and is stacked into a heat exchange body through a metal cover plate, a tie rod and a spring. It 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 the heat exchange area. , High temperature resistance, strong pressure resistance, excellent impact ability, small size, high utilization rate, easy to overhaul, 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.
Tubular graphite heat exchangers have the advantages of easy inspection of all seals, reduced pressure, large product specifications, and low prices. In the operating temperature, the limit temperature of tubular graphite heat exchangers is generally 130 degrees, while the round block The hole type graphite heat exchanger can reach 165 degrees. If there is a leak, the tubular graphite heat exchanger is mostly repaired by pipe plugging. If the pipe plugging exceeds a certain number, the heat exchange area and effect will be affected.
