Matters needing attention when feeding the glass lined reactor

When feeding the glass lined reactor, the feeding should be carried out in strict accordance with the time, sequence, speed, variety and quantity specified in the regulations, so as to effectively prevent the violent reaction in the tank due to the wrong ratio or too fast feeding. In addition, the following protective measures need to be taken:

1. When inputting bulk materials, it is necessary to process the bulk materials into small pieces and then put them in to prevent accidents caused by the block materials stuck in the cecum at the bottom of the tank or collide with the thermometer tube during stirring. At the same time, tools and bucket lids should be prevented during operation Other foreign objects fall into the glass lined reactor to prevent the collision of tools and other metals from generating sparks;

2. When vacuum pumping liquid materials, the vacuum valve should be opened slowly to prevent static electricity; when pumping low flash point materials, the pumping tube should be inserted under the liquid surface to prevent air from entering the tank and control the pumping speed to prevent generation Safety accidents such as combustion and explosion occur when static electricity encounters air;

3. When vacuuming Raney nickel and palladium charcoal and other flammable substances in contact with air, they should be soaked in a solvent, and while pumping, use a small amount of solvent to pour the Raney nickel and palladium charcoal sticking to the barrel wall. Air flammable substances are exhausted, and the suction pipe should be inserted under the liquid surface to prevent air from entering the tank and control the suction speed to prevent static electricity from burning and explosion when exposed to air. Then use a small amount of solvent to pump and wash the feeding pipeline to prevent safety accidents such as combustion and explosion of flammable substances remaining in contact with air.

4. The volume of the material in the tank is generally the best at the jacket position.

5. Two or more people must operate during feeding or other operations. At least one person must perform the operation and the other person will review it.

In addition to dosing in accordance with the required dosing acceleration and sequence, combined with the precautions that should be taken during the five-point dosing process, can the damage to the glass lined reactor be avoided, and more importantly, it can avoid burning and burning during production. Safety accidents such as explosions.
