The current development status of pneumatic conveying
Many current research results indicate that long-distance transmission has a significant impact on the concentration of urban air pollutants. Moody et al. Cluster analysis was conducted based on the similarity of backward trajectories, and it was found that the composition of precipitation was significantly different under the influence of different airflows. It was believed that the important factor causing this difference was the origin of the airflows. Cloak, etc. The clustering analysis of the backward trajectory explains the trace gas observation results of the Metz Point Observatory on the Irish coast. After eliminating the interference of local airflow, it was found that there were significant differences in ozone concentration under different air quality conditions.

As China's economic growth slows down, our leaders' development is also directed towards energy-saving and environmental protection equipment. With the continuous development of the global economy, my demand for various resources is constantly increasing. Due to the slow economic development of the country in recent years, resource conservation and cost reduction have become necessary choices for Chinese enterprises to reduce costs and achieve profitability; Despite the global economic downturn, China's pneumatic conveying equipment industry still has a fast development speed, but there are also many problems, such as low technological content of products, poor energy-saving and environmental benefits, etc. Faced with such a global landscape, the inevitable path for China's low-carbon and energy-saving cities to develop pneumatic transportation is also the trend of pneumatic transportation.

The transportation process with a solid content of 10-30kg/m3 or a solid to gas ratio greater than 25. The working wind speed is low, and pneumatic conveying is used. Mature equipment warehouse pumps have a conveying distance of over 500m and are suitable for long-distance transportation. However, this device has many valves and many pneumatic and electrical equipment. The conveying pressure is high, and all pipelines require wear-resistant materials. Intermittent aeration tank type dense phase conveying. Add the particles in batches to the pressure tank, then exhaust and blow them away. After reaching a certain pressure in the tank, open the discharge valve and blow the granular material into the conveying pipe for transportation. Pulse conveying is the process of introducing compressed air into the lower storage tank and dispersing the material. Blow another pulse of compressed air with a frequency of 20-40min-1 into the inlet of the conveying pipe to form a row of alternating material towers and a row of small air towers, which are pushed forward under the action of air pressure.

The left side of the curve is relatively steep. If the air velocity is within this range, the pressure loss in the pipeline will increase sharply, the velocity will decrease, and the conveyed material in the pipeline will begin to block until it can no longer be conveyed. Therefore, when selecting the conveying speed w, it should be on the right side of the tangent point of the curve. From the perspective of power saving, the transmission speed within the allowable range of w should be selected, but it should be ensured that it is on the right side of the tangent point of the curve. At this point, the resistance coefficient K ≠ f (w). The transportation of various materials is slightly different. In order to save energy and reduce energy consumption, using Nt, CO gas to transport explosive materials such as powdered media can achieve economic and safe effects, but attention should be paid to low oxygen during burial. When transporting various materials, safety measures should be taken in accordance with relevant regulations.
