Precautions when using graphite heat exchanger
Release time:
2022-07-06
Before starting, clean the debris in the graphite heat exchanger pipe to prevent the graphite holes from clogging. In order to extend the service life of the equipment, minimize the number of equipment stoppages. When the heat transfer capacity of the equipment decreases, stop the machine to check. If the graphite heat exchanger is seriously scaled, it can be cleaned by appropriate physical or chemical methods.
Precautions when using graphite cooler and graphite heat exchanger.
Before starting, clean the debris in the graphite heat exchanger pipe to prevent the graphite holes from clogging. In order to extend the service life of the equipment, minimize the number of equipment stoppages. When the heat transfer capacity of the equipment decreases, stop the machine to check. If the graphite heat exchanger is seriously scaled, it can be cleaned by appropriate physical or chemical methods. If the crystals in the pipes are clogged, they can be heated, melted and cleaned. Because graphite is a fragile material, mechanical processing is prohibited. The top and bottom of the casing are equipped with exhaust pipes, and the equipment is equipped with valves, which are connected to the exhaust pipes and do not allow the blind to fail. Before using the equipment, open the exhaust valve at the top of the housing and close it after the air in the housing is completely discharged. The non-condensable gas at the top of the shell and the condensate at the bottom of the shell should be discharged frequently during use.
The larger the particle size of the graphite substrate, the lower the packing density and the lower the mechanical strength. The larger the inter-granular pores, the more pores are exposed in the drilled holes and the porosity increases. In use, the impregnation dose is increased to meet the fineness requirement, which affects the impregnation quality and the thermal conductivity of opaque graphite. The greater the mechanical strength, the greater the density. Therefore, the selection of substrates with high bulk density stops the impregnation heat treatment, and the quality of the equipment consumed in processing is stable and safe for use.
Graphite heat exchanger impregnant filling graphite base material space. Different impregnation formulations directly affect the corrosion resistance of opaque graphite. The amount of impregnation affects the service temperature and corrosion resistance. Graphite heat exchangers and heat pipes in industrial production can scale and clog, affecting the heat exchange effect of graphite heat exchangers. In the heat exchange process, cooling water in the graphite heat exchanger appearance to form a solid scale, affecting the heat exchange effect.
Seriously, insufficient cooling water flow and depressurization will prevent production from running normally. In order to save cleaning costs, graphite heat exchanger scaling seriously affects production. Some enterprises will consider cleaning graphite heat exchanger, but do not realize that graphite heat exchanger with load will cause more and more damage to the equipment, resulting in increased failure rate.
Spiral plate graphite heat exchanger is mainly used for cleaning plate heat exchanger. In plate graphite heat exchangers, there are various types of fouling such as oil sludge/asphalt, grease, hydrocarbon deposits, etc. These fouling need to be removed. Depending on the degree of fouling of the equipment, graphite heat exchangers should be cleaned at intervals depending on their size.
If the heat exchange effect of graphite heat exchanger is unsatisfactory, it cannot meet the production requirements. In addition, graphite heat exchanger has a long service life and poor cooling water quality. So consider cleaning and find a professional cleaning company to clean it. Cleaning graphite heat exchanger, so that the equipment runs normally, restoring production and preventing danger.
