Reaction vessel is a kind of stainless steel container, the reaction equipment widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other industries used to complete the sulfide, nitration, hydrogenation, alkylation, polymerization and condensation process, it's to participate in the reaction material mix as the premise, for heating, cooling, and liquid extraction and gas absorption process of physical change all adopt mixing plant are needed to get to the good effect.

 

(1)     Install vessel cover, it should prevent the kettle body between the vessel lid sealing surfaces to knock against each other. The vessel cover fixed position carefully on the  body, tighten the nut, it must according to the diagonal, several times symmetrically gradually tightened The strength should be uniform, do not allow the kettle lid tilted to one side, in order to achieve good sealing effect.

(2)     Positive and negative nut connection place, only allowed turn positive and negative nut, two circular seal face shall not be relatively gyration, all nuts lines connection assembly, should besmear lubricating oil.

(3)     Seal type needle valve system line, just gently turn the needle valve, compressed the sealing cover, it can achieve good sealing effect.

(4)     By hand plate fixed on the kettle of rotors, to check whether running flexible.

(5)     Controller should be flat on the operating table, the reaction vessel its working environment temperature is 10 to 40 ℃, relative humidity is less than 85%, the surrounding medium not containing conductive dust and corrosive gas.

(6)     Check the moving parts on the panel and rear panel and the fixed contact is normal, smoking on cover, check whether the connector contact is loose, if there is damage caused by transportation and storage or rust of reaction vessel.

(7)     Stainless steel reaction vessel controller should be reliable grounding

(8)     Connect all wires, including the power cord, electric wire, electrical wire between the controller and the kettle and temperature sensors and speed wire.

(9)  On the panel "power" total air switch is closed, digital display table should be displayed.

(10)  On the digital display table set various parameters (such as upper limit alarm temperature, working temperature, etc.), Then press the "heat" switch, electric furnace through, at the same time, the indicator light on "heat" switch. Adjust the "surge" knob, can adjust electric furnace heating power.

(11) Press the "mixing" switch, mixing motor electric furnace heating power, the indicator light on "stir" switch at the same time, the slow turn knob "speed", to rotate the motor slow and see if the motor is positive, hang up correctly, stop the belt, and then restart.

(12) After the operation, can be natural cooling, cold over the cooled or water in bracket. When the temperature drop, and then released in the kettle with pressurized gas, the pressure to atmospheric pressure (pressure gauge shows zero), equal main nut symmetric unscrew again, then remove the nut, and then carefully remove the vessel cover, placed in the bracket.

(13) Under the condition of high pressure reaction vessel with pressure, can't for removal and replacement of the bolts, removing the pressure should be taken before for maintenance.

(14) High pressure reaction vessel cannot use super temperature and pressure, strictly in accordance with regulations of the use, are not allowed to be contained in the reaction liquid acid.

(15) Should be sent to supervise during the process of test, in case of gas leakage, should immediately stop the test.

(16) If long time need not high pressure reaction vessel, it must clean the internal, and then blow dry, but also with nitrogen protection, to prevent internal corrosion.

(1)     First the seal cone should pay special attention to take good care of, should avoid collision damage.

(2)     When install high-pressure reaction vessel cover, it should first place the reaction kettle body, then install the vessel lid carefully on the body.

(3)     Tighten the bolts, diagonal symmetric gradually tighten for many times, the strength should be uniform, do not allow the kettle lid tilted to one side, in order to achieve good sealing effect.

(4)     When the threaded connector assembly, should daub on oil or graphite. Damage of sealing surface, and if the damage is serious, it should be replaced.

(5)     Using steam heating reaction vessel, it should undertake heating two and tightness test, test it is best to use inert gas, resolute can't use oxygen or other inflammable and explosive gas.

(6)     The high-pressure reaction vessel heating or booster shall be carried out slowly. Heating speed should not exceed 80 degrees per hour, booster in every time, with 20% of the working pressure for the level, every level, should for 5 minutes, when reach to test pressure, residence time for 30 minutes, and check the seal.

(7)     When the reaction vessel react, it can't heat and cooling speed, otherwise may produce cracks due to temperature stress, After the reaction, it should be cooling, then deflated, make the pressure drop, and then unloaded bolts, order cannot be reversed.

(8)     After operation of stainless steel reaction vessel, remove the reaction kettle body, cover kettle residue. The main sealing mouth should often clean and keep clean

(9)     For measuring instruments, we should check regularly, to keep the metering accuracy of measuring instruments.

(10) High-pressure reaction vessel  of the coating should be kept intact, if there are any damage should be repaired, can't repair should be replaced.
