The reaction tank is one of the main equipments of chemical companies. As a sort of carding reaction container, in addition to mastering their model selection and operation steps, how to install a stainless steel plate reaction tank is also a top priority. The actual operation and subsequent steps are all based on the entire process of the equipment. Today's electric heating sinks give everyone a detailed introduction of the issues that must be paid attention to when installing the equipment:
1. Equipment natural environment:
The autoclave should be placed in a practical operation room that meets the requirements of explosion-proof type. When several autoclaves are installed, they should be placed separately. Each explosion-proof type must be separated by a solid explosion-proof brick wall. There are entrances and exits that lead to outdoor or safe passages immediately. When flammable and explosive substances are stored, the detailed address of the equipment should be guaranteed, and natural ventilation is good.
2.Equipment cover and seal:
The kettle body and the kettle cover adopt the spherical and arc-shaped surface contact sealing method. Tighten the main anchor bolts to make them tight to each other to achieve a very good seal. When tightening the main anchor bolts, do not exceed the tightening torque of 80 ～ 120NM. The overall plan prevents the sealing surface from being damaged by extrusion and overload. The sealing surface must be maintained in multiple ways.
When the kettle lid is installed, the kettle lid is started slowly from left to right to avoid collision between the kettle body and the middle sealing surface of the kettle lid. Tighten the main nut, it must be tightened gradually and symmetrically, and the force must be symmetrical, to achieve a very good sealing effect.
3. Connection of front and back nut:
At the connection of the front and back nuts, only the front and back nuts can be rotated. The two sides of the curved surface cannot be rolled over. For all external threaded connections in the equipment, the oil or fuel must be modified with high-purity graphite to avoid biting.
4. Application of gate valve:
Needle valve adopts line sealing, only need to quietly roll over the valve needle, and close the cover, you can achieve very good actual sealing effect, prevent the application of excessive force, and avoid damage to the sealing surface.
5. Reaction tank manipulator:
The control board should be placed on the actual operating table. The working temperature of the control board is 10-40 ° C, the humidity of the air is lower than 85%, and the surrounding materials are free of conductive floating dust and corrosive vapors.
6. Inspection of fixed contacts:
Check whether the moving members and fixed contacts on the control panel and the back panel are all normal. Remove the top cover, check whether the connector is loose, and whether it is damaged or rusted due to improper transportation and storage.
7. Connecting power lines:
Connect all power lines, including power plugs, heating furnace lines between the control panel and the kettle, motor lines, and temperature sensor and speedometer power lines.
8. Safety equipment:
The use of rupture disc equipment generally does not require simple disassembly and experiments. Once the project is blasted, it must be replaced from the beginning. The rupture disc that exceeds the blasting pressure of the calibration project without engineering blasting should be removed and replaced first.
9. Avoid excessive temperature differences:
Blocks rapid cooling and rapid heating during work to prevent excessive temperature differences from forming cracks. In addition, the water jacket between the magnetic stirrer and the lid of the kettle should be passed through cooling circulating water to avoid demagnetization of the magnetic tile.
10. Application of freshly installed kettle:
For new equipment (or repaired kettle), the pressure test must be carried out before funds can be invested in all normal applications. The substance is N2 or other rare gas, and the application of flammable and explosive materials is blocked. The experimental working pressure is 1 to 1.05 times the pressure. The pressure must be developed in stages. The interval is 0.25 times the pressure, and it is held for five minutes per level , Rise to experimental working pressure and stop for 30 minutes. If the leak is found, it should be depressurized and repaired before experimenting.
11. Opening of the autoclave:
After the autoclave has finished reflecting, first carry out refrigeration, reduce the temperature and then pressurize the gas to superheated steam. Loosen the anchor bolts, carefully remove the lid of the autoclave, and prevent pressure relief and disassembly.
12. Cleaning in the kettle:
Internal and external wall cleaning After each actual operation, the residue of the kettle and all sealing surfaces should be cleaned with cleaning liquid. Hard blocks or soft objects with uneven surfaces are not allowed to be used for cleaning.
Stainless steel plate reaction tanks are widely used in chemical plants, pharmaceuticals, food and other manufacturing industries. The raw materials are 304 stainless steel plates. Superheated steam stainless steel plate reaction tanks have the characteristics of rapid heating, heat resistance, corrosion resistance, environmental sanitation, and no air pollution .
