Laboratory reactor installation and use

Date of release:2018-09-10 Author: Click:

(1) installation place: the reactor should be installed in the high-pressure operating room that meets the requirements of explosion protection. When multiple reactors are equipped, they should be placed separately. The explosion protection wall should be separated between each two units.

(2) after opening the package, check whether the equipment is damaged. Install the equipment according to the equipment model and the structure diagram, and check the equipped parts according to the packing list. Heating mode if the heat conduction oil heating, please according to use to purchase the corresponding models of heat conduction oil temperature (note: the heat conduction oil are not allowed to contain water) to join, join the jacketed refueling upper open clamp and the upper part of oil level in the mouth open, through to refuel refueling mouth flow of oil to oil level, oil level screw mouth to death after, not to screw die lest produce pressure filler.

(3) installation and sealing of autoclave body and cover of autoclave reactor: Kettle body and kettle cover use gaskets or cone and circular arc line contact below, by mutual compression tighten the nuts to make them achieve good sealing effect, tighten the nut to diagonal symmetry gradually tighten the tension for many times, forcibly even, do not allow the kettle lid tilted to one side, in order to achieve good sealing effect, when tighten the nut shall not exceed the prescribed tightening torque 40 ~ 120 n. M range, to prevent wear and sealing surface is crushed or overload sealing face to be love, every time before you install the upper and lower sealing face with more soft paper or cloth to wipe clean, be careful not to cover the kettle body, kettle seal face with scars, If the sealing cover can be used for more than ten thousand times in a reasonable operation, it needs to be reprocessed and repaired to achieve good sealing performance. When removing the cauldron cover, the cauldron cover should be lifted up slowly up to prevent the sealing cover collision between the cauldron and the cauldron. If the seal is gasket seal (tetrafluorine, aluminum pad, copper pad, asbestos pad, etc.), a good seal can be achieved by tightening the main nut.

(4) the valve, pressure gauge and safety valve shall be installed by tightening the front and back nuts, so as to achieve the sealing effect. The circular sealing cover at both ends shall not be rotated relative to each other. Lubricant or oil-tempered graphite shall be applied to all screw fasteners during assembly, so as not to kill them. Use of valve: needle valve line seal, only turn the needle gently, pressure tight cover can achieve good sealing performance, do not force too much, so as not to damage the sealing cover.

(5) after the equipment is installed, a certain amount of nitrogen pressure is applied for 30 minutes to check whether there is any leakage. If any leakage is found, please use soap to find the pipeline and leak point at the pipe mouth. After finding the leakage, release the gas and tighten it.

(6) when cooling down and cooling down, water can be used for internal cooling through cooling coils. Quick cooling is prohibited to prevent excessive temperature difference stress, resulting in cracks in the coils and cauldrons. At work when the kettle temperature over 100 ℃, magnetic stirrer and the kettle cover jacket should be between cooling water, make water temperature is less than 35 ℃, in order to avoid magnetic steel demagnetization.

(7) safety device: positive arch type metal bursting disc is adopted and made of stainless steel. It is manufactured according to national standard gb567-89 technical conditions for arch metal blasting. It has been tested well when leaving the factory. If it has been exploded, it needs to be replaced. The term of replacement shall be determined by the user according to the actual situation of the user. If the explosion pressure exceeds the nominal blasting pressure of the bursting disc but is not exploded, it shall be replaced.

(8) after the reaction, first for cooling, and then the gas through the pipeline leakage within the kettle to outdoors, makes the pressure inside the kettle fell to atmospheric pressure, it is strictly prohibited to bring pressure to remove, then the main bolt, nut symmetrically to loosen, then carefully remove the kettle lid (or rising kettle lid) on the scaffold, must pay attention to the protection in the process of unloading cover sealing surface.

(9) cleaning cleaning in the kettle: after each operation, use cleaning liquid (use cleaning liquid to avoid corrosion on the main material) to remove residues of the kettle body and the sealing surface, and always clean and keep clean.
