Introduction to Powder pneumatic conveying, Powder pneumatic conveying advantages, characteristics and principles

Powder pneumatic conveyingthat is, the technology of conveying granular materials in closed pipes by air flow.，features include Save manpower, No secondary pollution, Strong adaptability, It is convenient to realize mechanization and The conveying speed is faster，is a common Powder pneumatic conveying，has been favored by more and more customers.。

1、Brief introduction of Powder pneumatic conveying

Powder pneumatic conveyingis a concrete application of fluidization technology to transport granular materials along the direction of airflow in a closed pipeline by using the energy of airflow.，the advantage is It can send materials concentrated from several points to one place or from one place to scattered points, and realize long-distance operation.、In the conveying process, various technological operations can be carried out at the same time.、The conveying system is closed.，Can effectively prevent moisture and sundries from polluting materials, fully sealed and pollution-free transportation.、Not only can the materials from multiple feeding points be transported to the unloading point in turn, but also the materials from multiple feeding points can be transported to the unloading point at the same time, and remote operation can be realized.、The pipeline layout is flexible, and it can be arranged according to the specific terrain.，support customization。

2、Powder pneumatic conveying use

The purpose of Powder pneumatic conveying is introduced as follows:

1. Adapt to complex environment

The Powder pneumatic conveying system can adapt to various complex environments and layout requirements. Whether in high temperature, high humidity, corrosive or flammable and explosive environment, the normal operation of the system can be ensured by selecting suitable materials and taking corresponding safety measures. In addition, the Powder pneumatic conveying pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

2. Process assistance

In some production processes, Powder pneumatic conveyings are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Powder pneumatic conveying system can cooperate with other equipment to realize process operations such as mixing, grading, drying and cooling of materials, and improve production efficiency and product quality.

3. Reduce pollution

The Powder pneumatic conveying system carries out material transportation in a fully enclosed state, which effectively reduces the environmental pollution caused by dust flying and material leakage.

4. Long distance transportation

The Powder pneumatic conveying system can realize long-distance material transportation and meet the demand of long-distance material transfer. This is especially important for some large factories or cross-regional material transportation.

5. save energy and cut emissions

Although the Powder pneumatic conveying system itself needs to consume some energy, compared with other transportation modes, it usually has higher transportation efficiency and lower maintenance cost. In addition, by optimizing the system design and adopting advanced energy-saving technology, energy consumption can be further reduced and the goal of energy saving and emission reduction can be achieved.

3、Powder pneumatic conveying structure

The Powder pneumatic conveying structure is introduced as follows:

1. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Powder pneumatic conveying 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.

2. 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.

3. control system

The control system is the "brain" of the Powder pneumatic conveying 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.

4. 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.

5. Air source device

The air source device is the power core of the Powder pneumatic conveying system, which provides the airflow power needed for transportation. Common air source equipment includes roots blower, compressor, centrifugal blower and water ring vacuum pump. These devices can generate stable airflow and provide sufficient power for the transportation of materials.
