In the pharmaceutical and chemical industry, it is not difficult to see small heating and low-temperature units.
For manufacturers, it is hoped that users operating small heating and low-temperature units should pay more attention to the use of equipment to avoid malfunctions caused by improper operation
.
Then, what should I do if the small heating and low-temperature unit is found to be insufficient in heat supply during operation? 1.
The user can choose to stop the cleaning.
This cleaning method is different from the traditional water-based cleaning.
The organic solvent is used to dissolve all the coking and sludge in the system in the cleaning agent, and the circulating pump is used to disperse and discharge it
.
Before cleaning, the system should be cooled first, and then all the heat-conducting oil in the system should be drained while it is hot, and then connected to the compressed air to purge it, and the residual oil in the system should be purged as much as possible
.
2.
It can be cleaned online without stopping.
This cleaning method is a cleaning method that is widely used and relatively cost-effective.
The cleaning agent is directly added to the high-level oil storage tank of the small heating and low-temperature unit in operation according to a certain proportion.
The cleaning agent will follow the heat transfer oil in the system to clean itself, mainly relying on the action of molecules to quickly penetrate the cleaning agent into the oil dirt layer, and decompose the insoluble oil dirt of macromolecules into oily structures of small molecules through special chemical action.
Therefore, under the action of the dispersant, the small molecular grease is incorporated into the heat-conducting oil, and the grease is removed with the physical action of the circulation of the heat-conducting oil.
After the system is cleaned, the old oil can be discharged and replaced with new oil
.
If the high-level oil storage tank of the small heating and low-temperature unit is often designed too short, this also leads to the rapid oxidation of the heat transfer oil in the system, resulting in insufficient heating
.
Because the heat transfer oil contacts with air at high temperature, it will accelerate its oxidation rate, and a lot of sludge will grow over time.
Once these sludges enter the system, they may become blocked, resulting in the decrease of the fluidity of the heat transfer oil in the hot plate and the temperature
.
