Pharmaceutical Network Technical Article: Glass reactor is widely used in petroleum, chemical, pesticide, pharmaceutical, food and other industries, used to complete vulcanization, nitrification, hydrogenation, hydrocarbonization, polymerization, condensation and other processes of the pressure vessel With the development of science and technology, the development of glass reactor industry is also gradually accelerating, types and functions continue to increase, widely used
Among them, the double-glazed reactor can be stirred under normal or negative pressure conditions according to the requirements of use, and can carry out the reflux and distillation of the reaction solution, with high temperature accuracy, small error, high efficiency advantages
Industry said that double-glazed reactor in the process of work, some places are easy to be ignored by operators, need to be highly valued Specifically, there are the following aspects
First, the choice of media, including thermal and temperature-controlled media Among them, due to the layer thickness in the middle of the double-glazed reactor is small, the insulation performance is poor Therefore, in the process of using high and low temperature, the use of insulation materials to protect the kettle body insulation For the reactor body and the tube of the guide fluid need to be wrapped with insulation material, and pay attention to the thickness of the insulation layer, to ensure a better insulation effect
In the selection of temperature control medium, the user can choose different nature of the temperature control medium according to the desired reaction temperature, as the reaction heat-transmitting medium When using low or high temperatures, be careful to select the right medium
"The key is viscosity The media circulation pump with too much viscosity may not move, and the circulation effect is not good, can not achieve a satisfactory temperature control effect And the rush to replace the high-power circulating pump, easy to damage the double-glazed reactor lining, so that the reactor rupture The industry said that, in general, manufacturers will be according to their own products, supporting the corresponding heating media for users to choose
Second, the storage location Double-glazed reactor as a reaction amplification test device, the volume is usually 50 - 150L, the volume can be customized in certain cases, so the scale of the test can not be underestimated As the kettle body is made of glass, stainless steel is a stand and the foot is a caster, so the storage location needs to be carefully selected
According to some user reactions, double-glazed reactor casters, although fixed, but not strong stability Therefore, the storage of attention to choose a flat place, as far as possible flat, and keep the mechanical mixing center and reactor consistent, otherwise easy to shake unstable, safety accidents In addition, the general floor-to-ceiling ventilation kitchen can not be placed, but must be placed in a good ventilated place
Third, the double-glazed reactor is an independent response shelf, and the reserved feeding port is small, so the feeding process is more difficult
Industry recommendations, for solid reagents, the recommendation is to be added to the kettle with a solution, while liquid reagents can be pumped into the kettle through a supporting pump or oil pump
It is worth noting that the reaction material is added to the reactor through the constant pressure drop hopper or the common drop hopper, and the corresponding moving ladder is required to allow the staff to join the test material
In addition, in the process of feeding, double-layer glass reactor disposable feeding volume should not be too large, according to the temperature of the reaction, return and pressure, after evaluation to add a suitable amount of material
In addition to the above precautions, users in the ordinary use of the process, also need to time the double-layer glass reactor maintenance, to ensure the life of equipment, reduce enterprise costs.
