For continuous reactions, how is the solid fed in?
Thread Content
I have a reaction that needs to be changed from batch production to continuous production; how can solids be processed in a continuous manner?
A storage tank is placed in the middle for intermittent feeding, to ensure that the material level in the tank remains above a fixed value; a screw conveyor (for mixing) is installed at the bottom of the tank and connected to the reaction unit. You can refer to the production process of anhydrous hydrogen fluoride to see how fluorite powder is continuously fed into the reactor.
I’ve learned about it; coincidentally, the company wants to install a similar system. Thank you
If the solid is a powder! High precision requires the use of weighing devices and feeders; if the requirements are not high, various types of quantitative feeders will suffice* (screw, belt, disc, rotary valve). . . . . . ) The physical properties of this material play a significant role! Of course, it is also possible to use an intermittent bin for repeated additions* (provided that the material allows for intermittent feeding). It’s not always possible to give a definite answer right away; only by understanding the specific circumstances, requirements, and conditions can an appropriate solution be found!
Well, if the reaction system is a non-pressurized one, then solid feed materials cannot be simply transported using conveyor belts; generally, it is necessary to turn them into a slurry and use slurry pumps or special feeding devices
Our company’s small equipment comes in the form of powder packs and material racks, with manual loading and unloading; large equipment doesn’t allow for automatic feeding. I would appreciate advice from those who are more experienced – QQ598561417
If measurement accuracy is required, a loss-weight feeder should be used
Add a weighing bin and an additional feeder; this can be achieved through interlocked control.
