Material conveying
Thread Content
We have a powdery material that is particularly difficult to feed; it hardly circulates when added to the tank, making feeding it extremely challenging. I checked, and someone suggested drawing on the coal powder conveying and feeding systems used in the pulverized coal gasification process. Could someone give a brief introduction to this specific method? ?
We added fluidized nitrogen at the bottom of the cone to loosen the pulverized coal; moreover, an aerator filled with nitrogen was installed in the feeding pipeline, and backblowing can be carried out when bridging occurs
Common auxiliary feeding measures include: 1. Air flow flushing for fluidization, 2. Mechanical vibration, 3. Using cone angles or scrapers to prevent bridging. Additionally, the appropriateness of the cone angle of the feeding bin has a significant impact. It is mainly necessary to figure out what is causing the difficulty in material cutting; the original poster has provided too little information about the operating conditions, making it difficult to determine the cause. Is the material fed into the reactor from a silo, or is it introduced directly through pipes? If pipes are used, the pipe diameter must be large enough; otherwise, given the sticky and clumping nature of the powder, it will cause problems. Only this large diameter yields the most significant effect. My QQ number is 756182412; I specialize in the processing of powders and granules.
Are there any photos of such equipment? You can send them so I can take a look
Feel free to discuss~ What’s your QQ number?
The transportation of powders follows the same principles as those of liquids, as a pressure difference is required. Additionally, when transporting powders, it is necessary to prevent bridging and blockages, which can be avoided by installing appropriate blowing devices; attention also needs to be paid to the design of the pipelines used for powder transportation.
