Two Main Types Of Cleaning Methods For Reactors

There are two main types of cleaning methods for Reactors: mechanical cleaning and chemical cleaning.

Mechanical cleaning: A high-pressure cleaning device is used to clean the reactor wall and the surface of the stirrer with a high-pressure water stream through the nozzle.

Chemical cleaning: The first step is to know the composition of the scale sample in the Reactor Equipment, preferably by taking a sample and analysing it. After determining the composition of the dirt, do a test and choose a cleaning agent that will not cause corrosion to the equipment metal. Then set up a temporary circulating device on site to circulate the cleaning solution in the equipment to wash away the dirt.

(1) First rinse the stirring paddle and kettle walls with an appropriate amount of water and drain.
(2) Flush the reactor with solvent through the pressurised device stream.
(3) If the cleaning effect is not achieved, add an appropriate amount of solvent to the reactor to warm up and stir the reflux until the cleaning requirement is achieved.Then the solvent is released.

(4) Finally, rinse the inner wall of the reactor with a certain amount of solvent and release.

The two methods have their advantages and disadvantages, chemical cleaning with less labour, short cleaning time, cleaning thoroughly, but may cause the equipment is corroded; mechanical cleaning will not produce corrosion of equipment, the hard scale can be effectively cleaned, but long, labour-intensive. Therefore, chemical cleaning is used in the softer, thinner dirt, mechanical cleaning is used in the hard, thick dirt conditions.
