Principle and Application of Negative Pressure Dense Phase Conveying System
The negative pressure dense phase conveying system is a conveying system that uses negative pressure to seal the material and gas together to the destination. The system is based on a negative pressure environment, I .e. a pressure below atmospheric pressure is maintained inside the conveying pipe. This allows the material and gas to be naturally sucked towards the outlet of the pipeline, and then through the sealed pipeline, the gas and material are transported to the destination together. The system uses a vacuum pump or a vacuum generator as a power source, and the working pressure is close to absolute vacuum. The negative pressure dense phase conveying system can realize multi-point to one point conveying.
In the process of negative pressure dense phase conveying, after the material is sucked into the pipeline, a dense phase flow is formed in the pipeline, that is, the material concentration is higher and the airflow velocity is lower. This flow mode helps to reduce the damage loss of materials and the wear of equipment, while improving the conveying efficiency.
Application of Negative Pressure Dense Phase Conveying
Negative pressure dense phase conveying technology has been widely used in many industries due to its advantages of high efficiency, energy saving, environmental protection and low loss, including but not limited:
1Chemical industryUsed to transport all kinds of powdered chemicals, such as aluminum oxide powder, calcium carbonate powder, silicon powder, etc. Negative pressure dense phase conveying can ensure the quality and purity of chemicals in the conveying process, reduce loss and pollution.
2, food industryIn food production, negative pressure dense phase conveying is used to transport fragile or lightweight materials, such as flour, dough, candy, nuts, chocolate beans, etc. This conveying method can protect the integrity and quality of the material and avoid crushing and pollution.
3Building materials industryIn the production of building materials, the conveying of cement, lime and other powdered materials generally adopts negative pressure dense phase conveying technology. The high-efficiency conveying system can meet the production needs of large-scale construction materials.
4Pharmaceutical industry: Negative pressure dense phase conveying system is also suitable for the pharmaceutical industry, used to transport pharmaceutical raw materials, tablets, capsules and other sensitive materials. Its hermetic and low-loss characteristics help protect the quality and purity of the drug product.
5Dairy industry: Transportation of raw materials, semi-finished products and finished products in dairy production.
6Other industries:Negative pressure dense phase transportation can also be used for the transportation of plastic raw material particles, raw materials in the new energy industry, and the treatment of toxic or difficult-to-transport materials in special industries such as nuclear energy and petrochemicals.
