The system’s operation cycle is too short
Thread Content
The unit I was involved in is the first of its kind in the country; it functions similarly to a vacuum distillation unit! ! The coal tar transported to the tank area reacts with a certain chemical agent in this facility, thereby removing metals such as aluminum, iron, and magnesium from the coal tar. Water is then removed through vacuum drying, and the coal tar is passed through a filter press to remove the solid residues resulting from the reaction with the chemical agent. The utilization rate of coal tar can reach around 97%. However, the residues produced by the reaction often clog the pumps, and they also accumulate inside the containers. Generally, the system needs to be purged every half month or so! It seems so troublesome; I hope everyone can offer some suggestions! Thank you!
Since it is number one in the country, it is understandable that problems arise, but there is still a long way to go before the first version reaches maturity. This requires identifying problems in the production process and continuously resolving and improving them until the equipment is finalized. It is recommended to improve the current production process by drawing on the technologies of other similar devices or of single-unit devices of the same type. It is advisable to suggest to the leadership that we go out and learn from others.
Try using a diaphragm pump and shorten the inlet pipeline. Send it back to the inlet and keep flushing.
Add a stirrer inside the container to prevent sludge from settling, and install filters at the pump inlet (several extra ones); if they get clogged, switch to another filter and have it automatically flushed to ensure smooth operation
Hello, moderator! I fully agree with your view. When it comes to selecting a pump, one should pay attention to this aspect: in situations where there is a lot of sludge, it is recommended to use pumps with large displacement such as rotary vane pumps, rotor pumps, or single-screw pumps (taking temperature into account for those with rubber stators). This way, the likelihood of blockages can be significantly reduced. I hope this can help you.
Yes, the type of pump can also be optimized based on the material conditions
