Reaction kettle heat transfer oil heater cleaning method
The heat-conducting oil heater of the reactor has been used at high temperature for a long time. Many manufacturers rarely replace the heat-conducting oil in the equipment, so that dirt and carbon deposits are formed on the pipe wall, which not only affects the production quality but also accelerates the aging of the equipment. There are even some manufacturers' reaction kettle heat transfer oil heaters that are not cleaned for a long time, so that a large amount of carbon deposits and carbon pollution are deposited on the bends of the pipes, resulting in local overheating and gas accumulation, causing pipe cracks or fuel injection, causing fires.
Reactor heat transfer oil heater
Therefore, in order to ensure the safe operation of the reactor heat transfer oil heater, we need to conduct a series of inspections on all accessories of the reactor heat transfer oil heater before operation, and also need to clean the reactor heat transfer oil heater regularly. De Machinery has summarized the cleaning methods of the reactor heat transfer oil heater and heat transfer oil furnace in the process of many inspections and maintenance, for your reference:
1. Drain the old oil and heat the equipment to about 50 degrees. After turning it off, the compressed air is purged so that the air pressure of the old oil is recommended to be 3 to 5 kg.
2. Equipped with cleaning liquid, add cold water according to the instructions of cleaning liquid, dissolve the cleaning agent, after preparation, add it to the oil furnace, and the liquid level can reach half of the position. Remember not to pour undissolved impurities into the heat transfer oil furnace.
3. After cleaning, turn on the oil circulation pump. When the pressure is stable, turn on the heating. At this time, the exhaust valve and the fuel tank cap need to be opened. Heat it to 90 degrees and keep the water in a non-boiling state, circulate for 10 to 12 hours, and discharge the cleaning agent and sewage.
4. Rinse, pour clean water into the reactor’s heat-conducting oil heater and heat-conducting oil furnace, heat it to 80 degrees, circulate for a period of time, and then drain the waste water. Repeat this process for 2-3 times of washing.
5. Blow dry, and use air to purge the water in the equipment as much as possible. Refill with new oil. Drain and degas according to the instructions for use of the heating furnace to meet the requirements of use.
Precautions in the cleaning process of the reactor heat transfer oil heater:
1. When heating during the cleaning process, it is necessary to strictly control the heating temperature to prevent the water from vaporizing and spraying out and scalding the operator.
2. The cleaning agent has a certain corrosive effect, and the cleaning personnel should wear rubber gloves.
3. After cleaning, remember to purge the system. It is recommended to use air or nitrogen during the purging process, and oxygen must not be used.
