Heyuan reaction kettle PU kettle has a long service life

Description :

　　Regular attention should be paid to the working condition of the entire equipment and reducer when maintaining the stainless steel reactor. If the reducer lubricating oil is insufficient, it should be replenished immediately. The electric heating medium oil should be replaced every six months. Safety valves, pressure gauges, distillation holes, electric heating rods, electrical instruments, and other parts such as the jacket and pot cover should be regularly inspected. If there is a malfunction, they should be replaced or repaired immediately. When the equipment is not in use, it is necessary to thoroughly clean the inner and outer walls of the container with warm water, regularly scrub the pot body, keep the exterior clean and the inner pot bright, and achieve durability.

　　The broad understanding of a reaction kettle is a stainless steel container with physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance need to be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. Pressure vessels must comply with the GB150 {Steel Pressure Vessels} standard, and atmospheric pressure vessels must comply with the NB/T47003.1-2009 {Steel Welded Atmospheric Pressure Vessels} standard. The pressure requirements during the reaction process also vary in terms of the design requirements for the container. Production must strictly follow the corresponding standards for processing, testing, and trial operation. Stainless steel reaction vessels vary according to different production processes, operating conditions, etc. The design structure and parameters of reaction vessels are different, that is, the structural style of reaction vessels is different, and they belong to non-standard container equipment.

　　When using a stainless steel reactor, the refrigerant inlet valve must be closed, the remaining refrigerant in the pot and jacket must be drained, and then the material must be input. The mixer should be started, and then the steam valve and electric power supply should be turned on. After reaching the desired temperature, the steam valve and electric power supply should be turned off first. After 2-3 minutes, the mixer should be turned off. After processing is completed, the remaining condensed water in the pot and jacket should be drained, and the sticky material should be washed away as soon as possible with warm water. Then, the inner wall of the container should be thoroughly cleaned with 40 ℃ -50 ℃ alkaline water, and rinsed with clean water. Especially when there is no material (heat absorbing medium) in the stainless steel reactor pot, the steam valve and electric power supply should not be turned on. Pay special attention to the use of steam pressure. Do not exceed the rated work pressure.

　　Operating procedures for stainless steel reaction kettle:

　　Before starting the stainless steel reactor

　　1. Check whether the kettle, mixer, rotating parts, auxiliary equipment, indicating instruments, safety valves, pipelines and valves meet safety requirements.

　　2. Check if water, electricity, and gas meet safety requirements.

　　Stainless steel reactor is in operation

　　1. Before adding materials, the mixer of the reaction kettle should be turned on first. When there is no noise and it is normal, the materials should be added to the reaction kettle, and the amount of materials added should not exceed the process requirements.

　　2. Before opening the steam valve, first open the return valve, and then open the intake valve. The steam valve should be opened slowly to preheat the jacket and gradually increase the pressure. The pressure inside the jacket should not exceed the specified value.

　　3. The steam valve and cooling valve cannot be started simultaneously, and hammering and collision are not allowed when the steam pipeline is out of air.

　　4. When opening the cooling water valve, first open the return valve, and then open the inlet valve. The cooling water pressure shall not be lower than 0.1 megapascals, nor shall it be higher than 0.2 megapascals.

　　5. The water ring vacuum pump should be started before supplying water. When stopping the pump, the pump should be stopped first and then the water should be stopped, and the accumulated water in the pump should be drained.

　　6. Check the operation of the reaction kettle at any time and stop for maintenance if any abnormalities are found.

　　7. When cleaning the titanium epoxy (enamel) reaction vessel, do not use alkaline water to brush the reaction vessel, and be careful not to damage the enamel.
