How to operate the autoclave correctly and normatively

High pressure reactor is widely used in petroleum, chemical industry, rubber, pesticide, dye, medicine, food, used to complete the process of vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other pressure vessels It is very important to install and use the high pressure reactor correctly 1 The autoclave shall be placed indoors When multiple autoclaves are equipped, they should be placed separately Each operation room shall be provided with an outlet directly leading to the outdoor or passageway to ensure good ventilation at the equipment ground point 2 During the installation of the kettle cover, the sealing surfaces between the kettle body and the kettle cover shall be prevented from colliding with each other Carefully place the kettle cover on the kettle body according to the fixed position When tightening the main nut, it must be tightened gradually according to the angle and symmetry several times The force shall be even, and the kettle cover shall not be inclined to one side to achieve good sealing effect 3 At the connection of the positive and negative nuts, only the positive and negative nuts shall be turned, and the two arc sealing surfaces shall not be turned relative to each other When all the nut pattern connection parts are assembled, they shall be coated with lubricating oil 4 For needle valve line sealing, it is only necessary to rotate the needle slightly and press the cover tightly to achieve good sealing effect 5 Turn the rotating body on the kettle by hand to check whether it operates flexibly 6 The controller shall be placed on the operating platform, with the working environment temperature of 10-40 ℃, relative humidity less than 85%, and the surrounding medium free of conductive dust and corrosive gas 7 Check whether the movable parts and fixed contacts on the panel and rear panel are normal, open the upper cover, check whether the connector contacts are loose, and whether there is damage or corrosion caused by improper transportation and storage 8 The controller shall be reliably grounded 9 Connect all wires, including power wire, electric furnace wire between controller and kettle, motor wire, temperature sensor and tachometer wire 10 Turn on the "power" air main switch on the panel, and the digital display meter shall show 11 Set various parameters (such as upper limit alarm temperature, working temperature, etc.) on the digital display meter, then press the "heating" switch, the electric furnace is on, and the indicator light on the "heating" switch is on Adjust the "pressure regulating" knob to adjust the heating power of the electric furnace 12 Press the "mixing" switch, the mixing motor is powered on, and the indicator light on the "mixing" switch is on Slowly rotate the "speed control" knob to make the motor rotate slowly Observe whether the motor is rotating forward If there is no error, stop the machine and hang the belt, and then restart it 13 After the operation, it can be cooled naturally, cooled with water or placed over the support After the temperature drops, the pressurized gas in the kettle shall be released to reduce the pressure to normal pressure (the pressure gauge shows zero), and then the main nut shall be unscrewed symmetrically and evenly, then the main nut shall be removed, and then the kettle cover shall be carefully removed and placed on the bracket 14 After each operation, the residue on the kettle body and lid shall be removed The main seal shall be cleaned frequently and kept clean It is not allowed to wipe it with hard or rough surface.
