[structure and characteristics]
In order to solve the problem that the allowable temperature of floating head tubular graphite heat exchanger is low, especially when it is used for heating, it is not ideal. The new type of hexagonal heat exchanger produced by our company adopts: single tube sealing, which is used to seal each graphite tube independently. It can expand and contract independently. It is suitable for heater and evaporator (rising film and falling film evaporation), and can withstand certain rapid cooling and heating. It can also be designed and manufactured according to the user's requirements or process conditions.
Design temperature: heating: ≤ 170 ° C
Design pressure: tube side: ≤ 0.1MPa
Shell side: ≤ 0.5MPa (can be increased to 0.7MPa according to user requirements)
Heat exchange area: 5 ~ 450m2
It is suitable for heaters and evaporators (rising film and falling film), and can withstand certain rapid cooling and heating.
(1) All seals are easy to check. If the graphite tube is damaged, it can be replaced at will;
(2) High heat transfer efficiency, corrosion resistance and long service life;
(3) It's cheap.
