Positive pressure dilute phase pneumatic conveying
Yinchi Environmental Protection divides the positive pressure dilute phase pneumatic conveying system into two types: medium and low pressure pneumatic conveying and high pressure conveying. The operation mode of these two types of positive pressure dilute phase pneumatic conveying systems is basically the same, with the difference being the different gas source pressure, conveying volume, conveying height, and conveying distance of the pneumatic conveying system.
Working principle of positive pressure dilute phase pneumatic conveying
The positive pressure dilute phase pneumatic conveying system uses a fan installed at the starting point of the conveying system to pass positive pressure air above atmospheric pressure into the feeder device. The material is added from the hopper and enters the feeder for quantitative feeding under the action of gravity. The material and gas are transported through the conveying pipeline to the separator or storage bin at the end point. After material and gas separation, the air is filtered and discharged into the atmosphere.

Characteristics and advantages of positive pressure dense phase pneumatic conveying system
This system is a pneumatic conveying system that uses a Roots blower as the air source and a rotating feeder as the feeding device to continuously press materials. The system has the characteristics of low conveying pressure, short conveying distance, and reliable conveying. It is suitable for dispersed conveying from one place to multiple places, playing a role in drying and grading materials; Due to the positive pressure of the system, even if there are gaps at certain connections in the components of the piping system, external air or rainwater will not invade; Materials are easily discharged from the discharge port.
1. The flexible configuration of conveying pipelines makes the production process of the factory more reasonable.
2. The conveying system is completely sealed, with less dust flying, which can meet environmental protection requirements.
3. Few moving parts, convenient maintenance and easy automation.
4. The high efficiency of bulk material transportation reduces packaging and loading and unloading transportation costs.
5. It can avoid moisture, dirt, and other impurities from being transported, ensuring the quality of transportation.
6. Multiple process operations can be achieved simultaneously during the conveying process.
7. Materials concentrated by counting points can be sent to one location or sent from one location to dispersed counting points, and remote operation can be achieved.
8. For materials with unstable chemical substances, inert gas transportation can be used.
