The reason for the explosion of the double-layer glass reactor

The inner container of the 50L double-layer glass reaction kettle is placed in the inner container, which can be vacuumed and stirred at a spee.
It is used for experiment, pilot test and production in chemistry, fine chemical industry, biopharmaceutical new material synthesis,et.
The product can be combined with high and low temperature fully enclosed circulator, circulating water multi-purpose vacuum pump, diaphragm vacuum pump, and low temperature coolant circulating pump to form a system devic.
The 50L double-layer glass reactor is made of high borosilicate glass, which has the characteristics of high temperature resistance, corrosion resistance, high hardness, low expansion rate and high light transmittanc.
Compared with ordinary glass, it is more like a plastic product with special propertie.
However, if we use the double-glass reactor improperly, it will inevitably cause damage to the double-glass reactor, and even crack in severe case.
Next, we'll take you through the reasons for this and how to effectively avoid i.
Violent reaction of materials will cause the reaction kettle to burs.
Some chemical reactions are exothermic reaction.
When the reaction temperature exceeds the specified temperature, the violent reaction of materials will produce a large amount of gas, which will cause the pressure in the kettle to increase sharply, thereby deforming the inner wall of the double-layer glass fa.
.Causes a large explosio.
Solution: First, pay attention to control the change of material reaction temperature during operation to prevent violent reaction caused by excessive temperature; second, install pressure relief device to automatically decompress when the pressure in the kettle increase.
Another situation is that when the two materials come into contact, a large amount of reaction heat is generate.
When the material is close to the wall of the kettle, the heat release causes the temperature difference to change sharply, causing multiple point-like burst.
Overpressure of the jacket will cause the reactor to burs.
When chemical enterprises use the steam output from the power plant to supply heat for production, the steam output from the power plant can only be used after decompressio.
Once the pressure reducing valve fails, or the safety valve of the steam buffer tank fails, the high-pressure steam output from the power plant is directly input into the jacket of the 50L double-layer glass reactor, resulting in overpressure of the jacket, and the wall of the kettle protrudes due to the external pressure, causing a large area of ​​burstin.
.Solution: add a pressure reducing valve on the basis of the existing pressure reducing device, and change the first-level pressure reduction to the second-level pressure reduction, so as to achieve double insuranc.
In addition, the working condition of the pressure reducing valve should be checked frequently, and any problems should be replaced immediatel.
Some should check whether the steam safety valve is in the correct working state, especially the spring safety valve should keep it working in a clean environment, and there should be no corrosion or jammin.
