How to use high pressure reactor safety?
High pressure reactor
is also popular as polymerization reactor, high pressure digestion tank, hydrothermal reaction vessel, pressure solution, digestion tank.High pressure reactor
is widely used in petroleum chemical industry, biological medicine, materials science, geology chemistry, environmental science, food science, commodity inspection,etc. -
High pressure reactor safety operation
, we need to pay attention to the following points:1.The high pressure reaction vessel
should be placed in the high-pressure operation room that meets the requirements of explosion protection. The operation room should have an outlet directly leading to the outdoor or channel, and the high pressure reactor should have reliable grounding.2.High pressure reactor
is usually sealed with conical contact through the sealing ring, and the main bolts are tightened to make them compact with each other to achieve the purpose of sealing.Therefore, the sealing cone surface must be specially taken care of to avoid all kinds of collision and resulting in its damage.3.When installing the cover, please place the high pressure reaction kettle
body first, and then install the kettle cover in a fixed position. Carefully install it on the kettle body. When tightening the main bolt, it must be tightened diagonally, force should be uniform, do not allow the kettle cover to tilt to one side, so as to achieve a good sealing effect. -
4.High pressure reactor
should be heated and pressurized before use. The test medium can be nitrogen. Oxygen or other inflammable & explosive gases are strictly prohibited.5.Temperature rise and pressure rise must be carried out slowly, and the temperature rise rate shall not be greater than 80℃/h. During pressure test, please connect the air inlet valve of the autoclave
to the cylinder with connecting pipe. The pressure boost must be carried out in several times, with 20% working pressure as the interval, and stay for 5 minutes per rising level, and stay for 30 minutes when rising to test pressure, to check the sealing condition.The experimental pressure is 100~105% working pressure.6.Fast cooling and fast heating are forbidden during the reaction process to prevent excessive temperature stress from causing cracks in the high pressure tank
body. -
