Background

Pneumatic conveying, also known as air flow conveying, is a specific application of fluidization technology, which utilizes the energy of air flow to convey granular materials in an enclosed pipeline along the direction of the air flow. Pneumatic conveying can be roughly divided into two types, suction type and pressure type, according to the working principle. The suction-delivery type pneumatic conveying is that the air and material are sucked into the pipeline together and conveyed by the low-pressure air flow, so it is also called vacuum suction-delivery. The pressure-feed pneumatic conveying is to convey the material by pushing the material with compressed air higher than atmospheric pressure.

The negative pressure conveying is mainly realized by forming negative pressure in the running process through an air inducing device at the tail end of the conveying system, and the negative pressure and the external pressure difference become power to convey. Because of the existence of pressure difference, the outside air is sucked into the pipeline, the put materials are brought into the pipeline along with the movement of the air, after the materials reach the terminal point, the materials are separated from the air and collected, and the air is purified and then is discharged into the atmosphere or recycled.
