The pneumatic conveying is a solid bulk material transportation form commonly used in the chemical industry. The efficient and stable conveying system is the necessary condition to ensure the production equipment under continuous operation.
The pneumatic conveying equipment is widely used in the power factory coal ash, cement transportation raw cement, alumina plant conveying alumina powder, powder and other powder materials. Products are widely used in the electric power, metallurgy, chemical industry, building materials, and hydropower.The pneumatic conveying has characteristics of high efficiency, energy conservation and environmental protection.In the food aspect, the gourmet powder factory is applied to transporting granular MSG, chicken essence, mushroom extract, etc. The brewery to transport rice, barley malt, etc. In pneumatic conveying has many successful application examples in many fields, mainly used for granular, powdery materials,such as fly ash, limestone, calcium carbonate powder, silica powder, PEC plastic particles, perlite, urea particles, organic silicon powder, quartz sand, cement, etc. Compared to the mechanical transmission. it has more energy consumption, particles are easily damaged. The equipment is also vulnerable to erosion. it has bigger water content and it is adhesive or is prone to produce electrostatic material in high-speed movement, unfavorable for pneumatic conveying.
The Shanghai world expo puts forward the theme of "city makes a better life". One of the important connotation is about its "green, low carbon, ecology, environmental protection". So we put forward the "intelligent garbage pneumatic conveying system. At present, Shanghai has formed the environmental air quality monitoring system composed by 46 continuous automatic monitoring stations, covering the expo park, the park around and the entire city of Shanghai, and formed the environmental air quality monitoring network with more than 30 city environmental monitoring stations of the Yangtze river region, comprehensively monitoring and timely releasing information to the public environmental air quality.The 24-hour environmental air quality forecast and 48-hour high pollution warning system have also been developed, which are easy for taking the corresponding measures when the pollution occurs under special pollution meteorological conditions.
It is understood that the expo region has a "intelligent garbage pneumatic conveying system," this is a very advanced garbage collection methods. The pneumatic garbage conveying system just begins to be used in some developed countries.The usage efficiency is not very high. Some visitors may not know this is trash on the ground. After the garbage into the facility can vacuum negative pressure collected in a storage box, avoid "run, run, drip, leak. These collection methods, in this giant city Shanghai, this is a more environmentally friendly method. It can transport the trash of the city center to the collection points, avoiding the frequent operation that the sanitation garbage truck does in the blocks and it also can reduce traffic jams, a advanced garbage collection method representing the future. After using in the world expo, the system will sum up experience, and it will be gradually popularized in some streets in Shanghai. We have reasons to believe that the "intelligent garbage pneumatic conveying system will be gradually penetrated into our lives.
