What is the reason for the reverse wind of the roots blower conveying slaked lime?

Visiting the forum these days, I saw a small partner asking about the reverse wind problem of Roots blower conveying hydrated lime. As we all know, roots blowers, which are used in environmental protection production, are also used as pneumatic conveying systems. Xiaobian has learned a little from this knowledge, which seems to be able to answer this question, but Xiaobian's technology is very good, so he can only answer it a little. Please leave a message and correct anything wrong.
Pneumatic conveying blanking
The forum partner said: please ask a question: the air volume is 8.21 cubic meters per minute, the air pressure is 49kpa, the DN80 pipeline, the conveying capacity is 500kg, and the material is sent to the venturi through the screw. When the material is increased, the wind will turn back. Thank you!
In fact, the parameters given by the partners in the forum are insufficient. Xiaobian can only guess the reasons for the anti wind based on past experience:
1. Selection of Roots blower
The roots blower is not selected according to the requirements of pneumatic conveying, which may cause the problem of material reverse air. But generally speaking, the relevance with roots blower is not so high (when the unloading equipment is sealed very well)
2. The sealing problem of the blanking equipment will also lead to anti gas
The sealing problem of the blanking equipment may be the most critical cause of the anti gas problem. Here, the editor shares a video on guiding environmental protection to solve anti gas problems for customers
