The structure of dilute-phase positive pressure conveying is relatively simple, primarily consisting of an air supply device, a feeding device, a conveying pipeline, a dust removal device, etc. The Roots blower is located at the front end of the system to provide pressure for the pipeline. Dilute-phase pneumatic conveying systems are divided into dilute-phase positive pressure pneumatic conveying systems and dilute-phase negative pressure pneumatic conveying systems. This article mainly introduces the dilute-phase positive pressure pneumatic conveying system

The advantages of dilute-phase pneumatic conveying lie in its fast conveying speed, small footprint, and automatic control capabilities. Furthermore, dilute-phase pneumatic conveying can avoid some issues found in traditional mechanical conveying, such as wear, material blockage, and leakage. Therefore, dilute-phase pneumatic conveying has been widely applied in many fields.

1. Friendliness towards granular materials

With strong adaptability, dilute-phase positive pressure conveying can effectively reduce particle damage and dust generated during the conveying process. This makes the system particularly suitable for conveying materials with high requirements for appearance and integrity, such as food particles and plastic raw materials.

2. Flexible arrangement and wide coverage

The flexible pipeline layout of the dilute-phase positive pressure conveying system meets the needs of enterprises for multi-point feeding and multi-point receiving, and can cover complex production environments involving multiple floors and workshops.

3. Environmentally friendly and sealed to prevent pollution

The entire process is conducted in a closed environment, preventing the leakage of materials contaminated by the outside world. The dilute-phase positive pressure conveying system effectively reduces dust spillage, protects the workshop environment, and reduces cleaning costs, meeting modern environmental protection requirements. It is suitable for granular materials with high dust content, such as chemical raw materials and cereals.

4. Stable operation and easy maintenance

The dilute-phase positive pressure system boasts a simple structure, with no mechanical components inside the pipeline. This design eliminates vibration and complex mechanical wear during operation, resulting in lower maintenance costs.

III. Application of Dilute-phase Positive Pressure Conveying in Particulate Material Conveying

1. Plastics industry: transporting plastic granules and color masterbatch, ensuring the integrity of materials, and adapting to process requirements such as injection molding and extrusion;

2. Food industry: used for conveying granular food ingredients such as grains, coffee beans, and sugar, ensuring hygiene and efficiency during the conveying process;

3. Chemical industry: transporting chemical additives and granular chemical products, adapting to the process characteristics of multiple batches and small material types;

4. Building materials industry: used for the transportation of building materials such as cement particles and quartz sand, meeting the needs of long-distance and high-efficiency transportation.

The dilute-phase positive pressure pneumatic conveying system, characterized by its high efficiency, safety, and environmental friendliness, utilizes high-speed airflow to propel material conveyance, making it an ideal choice for granular material transportation. This system has demonstrated excellent performance and reliability across multiple industries, ranging from plastics and food to chemical and building materials. It brings higher efficiency and economic benefits to enterprise production lines.
