How are graphite coolers to be used?

With the continuous development of society, graphite cooler material has been applied to our life, due to the excellent performance of graphite material, graphite-based graphite heat exchanger and other graphite equipment has been developed. Graphite equipment has played an important role in the chemical industry since it was put on the market. What are the cleaning methods for graphite coolers?

What happens when a graphite heat exchanger develops a leak?

Graphite heat exchanger is one of the graphite equipments that we commonly use nowadays, and we should pay attention to some matters when installing it, because it is easy to be damaged if it is not installed correctly. Among the installation location requirements are:graphite heat exchanger should be placed on the bracket that meets the height requirements and should be reliably balanced, in addition, a purge valve should be installed to prevent parking and purging to avoid accidents.

Graphite heat exchangers are environmentally friendly and powerful

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

Where does graphite heat exchanger fouling come from?

For commonly used graphite heat exchangers, according to the scaling mechanism, scaling is generally divided into the following categories.

What are the advantages of graphite absorbers?

In terms of equipment investment, compared with the previous equipment products, graphite absorber has a substantial reduction in investment, each absorption line reduces a graphite absorption device, which can be seen that the device has a great advantage. Reduces the operating cost of graphite absorber. Absorption tower packing part of the adiabatic absorption tower, graded absorption technology in the absence of secondary absorption tower circulating water cooling program, reducing the consumption of cooling water.

Graphite heat exchanger with thermal storage and inter-wall heat exchangers

Intermediate wall heat transfer this kind of heat exchanger is also called surface graphite heat exchanger or indirect graphite heat exchanger, using graphite heat exchanger for hot and cold separation, with a solid wall to transfer the heat to the other side, which avoids mixing of the two kinds of fluids, but also achieves the purpose of heat exchange of the two kinds of fluids. Therefore, this kind of heat exchanger is widely used in chemical and petroleum industries. There are many kinds of spacer type graphite heat exchanger, among which the widely used one is shell and tube type graphite heat exchanger, which mainly consists of shell, tube plate arranged in parallel and fixed with the tube bundle, baffle plate, end cover and so on. In operation, it is assumed that the hot fluid flows through the pipe to release heat, which is transferred from the pipe wall to the outside of the pipe, while the cold fluid flows out through the pipe to take away the heat, and the two fluids exchange heat without mixing.

What should I pay attention to when using a graphite heat exchanger?

Before starting the graphite heat exchanger, clean the debris in the process pipe to prevent the graphite air holes from clogging, minimize the number of equipment stops, and prolong the service life of the equipment, and stop checking the equipment when the heat transfer is reduced. If the equipment is seriously contaminated, it can be cleaned by appropriate physical or chemical methods. If there are crystals clogged in the pipe, it can be cleaned by heating and melting. Since graphite is a brittle material, mechanical methods are strictly prohibited. The exhaust (cleaning) pipe is installed in the high (low) part of the housing. When installing, the valve should be installed, and then connect the exhaust (cleaning) pipe, it is strictly prohibited to blindly use the blind dead. Equipment first use

Graphite heat exchanger leakage causes and solutions

Everyone should be familiar with graphite, which is found in many devices and materials. Graphite heat exchanger is a kind of equipment to process graphite material, its appearance meets the market demand for graphite, but if there is a failure, it will greatly affect the characteristics of graphite. When there is a two-phase medium leakage problem, first of all, we should check whether there is a problem with the quality of graphite, and then check whether the graphite heat exchanger bonding is normal, whether there is a dissolution phenomenon , aging or deterioration, the solution: the quality of the problem needs to be replaced, the glue needs to be re-glued, balanced the impact of the force, and drained of water in advance. Graphite tube fracture may be the equipment in the operation of the feed rate

Graphite heat exchanger use to pay attention to these

Graphite heat exchanger use precautions: the use of the process is strictly prohibited over-temperature and over-pressure operation, to avoid sudden changes in temperature and pressure, the cut-off valve should be opened slowly, and gradually adjust the size. Steam heating to avoid the violent impact of steam, slowly increase the temperature during the operation of the equipment, when the temperature of the graphite parts become uniform, slowly increase the pressure until it reaches the normal working pressure, the operation of the thermal process is very important. Operation process: first pass the cold carrier (material medium), after filling the equipment pass the hot carrier (steam or hot water); stop the hot carrier (steam or hot water) should be stopped, and then cool the equipment, the cold carrier (material medium) not
