The cleaning of pharmaceutical reactors is very important, mainly divided into chemical cleaning and mechanical cleaning. Below, we will look at these two cleaning methods!
First, chemical cleaning: First of all, we must know the scale components in the equipment, preferably sampling analysis. After determining the dirt composition, the test is first carried out, and the cleaning agent is selected as a cleaning agent and the test is carried out to determine that the metal of the device does not cause corrosion. Then, the cleaning liquid is circulated in the equipment by erecting a temporary circulation device on the spot to wash away the dirt.
Second, mechanical cleaning: the use of high-pressure cleaning device, 150-200MPa high-pressure water through the nozzle to wash dirt.
The two methods have their own advantages and disadvantages. The chemical cleaning has less labor, the cleaning time is short, the cleaning is thorough, but the reaction kettle may cause corrosion of the equipment; the mechanical cleaning will not cause corrosion to the equipment, and the hard dirt can be effectively cleaned, but the duration and labor High intensity. Therefore, chemical cleaning is applied to soft and thin working conditions, and mechanical cleaning is applied to hard and thick working conditions.
