2、Advantages of Dense phase pneumatic conveying system principle

Dense phase pneumatic conveying systemat work,Compressed air or other gases are passed through the air supply device to generate airflow, forming a certain airflow speed and pressure. Subsequently, the material is sent into the conveying pipeline through the feeding device, and under the action of the airflow, the material particles are suspended in the airflow or flow along the pipeline in groups. This gas-solid two-phase flow state enables materials to be transported to the target position along the pipeline. In the process of transportation, gas-solid separator (such as dust collector) is used to separate materials from air to ensure the quality of transported materials.，the advantage is High conveying speed, good conveying quality and high conveying efficiency.、In the process of conveying, various technological operations can be carried out at the same time, such as dry.、The conveying system is closed.，Not affected by environment, climate and other conditions, fully sealed and pollution-free transportation.、It is suitable for centralized transportation from many places to one place, with one or several feeding points, and realizes long-distance operation.、The conveying system is closed, which can prevent the materials from being affected with damp, soiled and mixed with other sundries in the conveying process, and ensure the conveying quality of the materials.，meet the needs of material transportation。

4、Structural characteristics of Dense phase pneumatic conveying system

The Dense phase pneumatic conveying system has the following structure

1. control system

The control system is the "brain" of the Dense phase pneumatic conveying system system, which is responsible for monitoring and controlling the whole system. Through the control equipment such as programmable controller, the parameters such as airflow speed, feed rate and system pressure can be accurately adjusted and controlled to ensure the stable operation of the system and meet the production requirements.

2. Feeding device

The feeding device is responsible for feeding materials evenly and stably into the conveying pipeline. It is usually installed at the beginning of the system, and uses the negative pressure or positive pressure formed by the air source device to mix materials with air in a certain proportion and send them into the pipeline. Common feeding devices include rotary valves, screw conveyors, rotary feeders, screw pumps, silo pumps and Venturi nozzles. The selection of feeding device should be considered comprehensively according to the characteristics of materials and transportation requirements.

3. Bunker system

The silo temporarily stores and releases materials. The silo is usually designed as a pyramid or conical structure to facilitate the storage and unloading of materials. The design of silo needs to consider the different problems of materials in the process of storage and unloading and the flow form of materials.

4. Conveying pipeline system

The conveying pipeline is a channel for conveying materials after mixing with airflow. It is made of wear-resistant and corrosion-resistant materials to ensure that the materials will not be polluted or damaged during transportation. The diameter, shape and length of the pipeline will be designed according to the characteristics and delivery capacity of the transported materials. In addition, the pipeline system may also include some auxiliary fittings, such as valves, elbows, expansion joints, etc., for regulating air flow and pipeline connection.

5. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Dense phase pneumatic conveying system system. It is responsible for handling the dust and waste gas generated in the transportation process to ensure that the discharge meets the requirements of environmental protection. Dust removal system usually includes dust collector, fan and discharge pipeline. According to different material characteristics and environmental protection requirements, different dust removal equipment and technical schemes can be selected.
