Graphite heat exchangers are environmentally friendly and powerful
Release time:
2021-12-13
Graphite heat exchanger is easy to use, environmentally friendly and durable, according to the medium classification of the heat exchanger to develop a reasonable maintenance plan, measures and deadlines, and according to the development of the maintenance plan and measures to implement carefully. Calcium chloride solution is mainly circulated in the axial material holes of the graphite heat exchanger, and we know that calcium chloride solution is easy to precipitate, and when the concentration of calcium chloride solution reaches 50% with the increase of temperature, it is very easy to crystallize and block the material holes, which ultimately leads to the shutdown. Therefore, in the production must strictly control the analysis process temperature indicators to ensure the concentration of calcium chloride, to maintain safe operation, and plan for shutdown maintenance, I suggest that the calcium chloride solution in the system should be
Graphite heat exchanger is easy to use, environmentally friendly and durable, according to the medium classification of the heat exchanger to develop a reasonable maintenance plan, measures and deadlines, and according to the development of the maintenance plan and measures to implement carefully. Calcium chloride solution is mainly circulated in the axial material holes of the graphite heat exchanger, and we know that calcium chloride solution is easy to precipitate, and when the concentration of calcium chloride solution reaches 50% with the increase of temperature, it is very easy to crystallize and block the material holes, which ultimately leads to the shutdown. Therefore, in the production must strictly control the analysis process temperature indicators to ensure that the concentration of calcium chloride, to maintain safe operation, and plan downtime maintenance, I recommend that the system of calcium chloride solution should be discharged from the lowest point of the system to recover, and then add hot water to the system, the circulating water pump circulating flushing graphite heat exchanger type round block holes at least two times until the equipment is released clean water, which is maintenance after graphite heat exchanger equipment Service life is very helpful.
Graphite is used because it is acid-resistant, corrosion-resistant, excellent thermal conductivity, graphite core is made of block hole structure, vertical and horizontal isolation from each other, when the two media pass each other, the high-temperature media constantly transfer heat to the graphite heat exchanger, the low-temperature media constantly from the heat exchanger to obtain heat, and then complete the heat exchange.
Graphite heat exchanger changes the heating method of acid, so that the acid heating is uniform, shorten the heating time, reduce the steam consumption, reduce the power waste, improve the work efficiency; acid mobility increases, the strip surface has a certain scouring effect, accelerate the descaling process, compared with the direct heating of steam heating of acid heating, due to the change in the heating method, the acid of the acid superheated evaporation and condensate on the dilution of acid is obviously Weakening.
