In addition to selecting the right model, there are several matters needing attention in the use of high-pressure reactor

High pressure reactor is widely used in chemical, food, medicine and petrochemical production It is a pressure vessel for evaporation, synthesis, polymerization, saponification, sulfonation, chlorination, nitrification and other processes In recent years, with the rapid development of medicine, food and other industries, the demand for high-pressure reactor continues to expand It is understood that compared with imported high-pressure reactors, domestic reactors in China have problems such as late start and slow development, and the industrialization of domestic reactors has always been the focus of national attention With the continuous breakthrough of industry technology and the continuous efforts of reactor enterprises, the domestic high-pressure reactor can basically meet the market demand, the market presents a good development trend, and the competition between enterprises is increasingly fierce Some insiders said that in order to ensure the normal function of the high-pressure reactor, users must pay attention to the following major matters besides selecting the right and normal equipment The operation of high-pressure reactor requires the correct operation of high-pressure reactor to ensure the normal and stable operation of the equipment and bring more benefits to the enterprise According to the suggestions of relevant technicians, the author combs out the following major operation requirements First, the high-pressure reactor needs to meet the conditions of test pressure, use pressure and use temperature on the main vessel at the designated place, and operate according to the use instructions within the allowable conditions It is pointed out in the industry that the reaction under high pressure, in particular, has higher requirements on the experimental site Therefore, in the process of experiment, we must select the experimental site according to the requirements of the experiment Secondly, the autoclave belongs to the precision equipment, so it is necessary to protect the sealing cone to avoid the damage caused by various collisions For example, when installing the cover, the reactor body should be placed first, and then the cover should be installed on the reactor body carefully according to the fixed position When tightening the main bolt, it is necessary to tighten it symmetrically in several times according to the angle The force should be even The cover of the kettle is not allowed to incline to one side, so as to achieve good sealing effect It is not allowed to exceed the specified tightening torque, so as to prevent the sealing surface from being squeezed or accelerated wear Third, check the equipment regularly Operators shall regularly check, repair and maintain all vessels and reaction equipment of the high-pressure reaction kettle If any damage is found, it must be replaced in time Otherwise, users operate without knowledge, and the consequences are unimaginable In addition, before using the equipment, users also need to carefully check all kinds of safety devices, especially safety valves, so as to ensure the safety of the experiment Fourthly, the specific pressure gauge should be selected for the high-pressure reactor, generally the oxygen special pressure gauge If the other gas pressure gauge is chosen carelessly, it may cause unimaginable consequences The cleaning of high-pressure reactor requires that in addition to the correct operation, the high-pressure reactor also needs to be cleaned correctly Generally speaking, the cleaning requirements of high-pressure reactor are divided into three points First, fill the reaction solvent into the kettle from the exhaust valve, wash most of the residues, and then inject water into the kettle for mixing for 10 minutes, then open the kettle cover and clean the inner wall of the kettle Second, when cleaning, the cover and sampling valve must be cleaned At the same time, when there is water in the kettle, a little nitrogen should be filled Third, for the reaction kettle not used for the time being, 70% of the volume of clean anhydrous ethanol can be added into the reactor to soak, and the screw can not be tightened After the autoclave is cleaned, it can be used next time conveniently.
