(Summary description)The conveying method of the positive pressure dense phase pneumatic conveying system is to use the pressure higher than the gas to push the material through the conveying pipeline with the positive pressure, so it is often called the high pressure-low speed system. The positive pressure dense phase pneumatic conveying system has a lower material to gas ratio. The initial velocity of the positive pressure dense phase pneumatic conveying system is about 120m/min, and the final velocity is about 1200m/min higher than the initial velocity. The pressure of the delivery pipeline is generally 3kg/cm2, and the pressure at the end of the system is almost zero. The positive pressure dense phase pneumatic conveying system uses an air compressor as the power source, which is characterized by low conveying speed and little impact on material quality. At present, the use of positive pressure dense phase pneumatic conveying system has been very extensive. At the same time, for different conveying materials, different conveying methods can be selected to maximize the performance, efficiency and economic advantages. This method is generally suitable for conveying pipelines and fine-grained, granular, abrasive and non-abrasive materials over long distances, as well as other materials that are difficult to convey. Such as PVC powder, bauxite, cotton candy, milk powder, soda powder, fluorite powder, aluminum fluoride, silica gel powder, etc. The positive pressure dense phase pneumatic conveying system is mainly composed of conveying tank, conveying pipeline, pipeline intensifier and electronic control part.   Workflow of positive pressure dense phase pneumatic conveying system During the feeding process, the material is fed into the feeding trough under the action of gravity through the double butterfly valve or the expansion butterfly valve. The replaced air is released through the exhaust valve, making feeding easier. Once the transfer tank is filled (the material level shows that the material reaches 90% of the tank volume), the feed valve and the exhaust valve are closed and sealed at the same time. The air supply for the line intensifier is provided by another set of additional pipes. The main function of this pipeline is to provide air source for the supercharger on the main conveying pipeline. When the supercharger pressurizes the main pipeline, the internal check mechanism prevents the material in the conveying pipeline from entering the supercharger and auxiliary pipelines. For materials that are very difficult to transport or have a high specific gravity, the installation distance between turbochargers is short and vice versa. When the material in the conveying pipeline is nearly empty, the pressure drop in the conveying tank is zero, and the gas supply valve is immediately closed, and the remaining gas is discharged from the conveying pipeline.   The positive pressure dense phase pneumatic conveying system is characterized by lower gas flow and lower conveying pressure throughout the conveying process. The advantage of the positive pressure dense phase pneumatic conveying system is that it can realize long-distance non-clogging pipeline transportation, and can transport more types of materials, which can greatly save operating costs.
