pneumatic conveyingSystem for conveying bulk materials
Pneumatic conveying system is used to transport bulk materials. Compared with traditional mechanical transportation and automobile transportation, it has higher transportation efficiency. The equipment has simple structure and is easy to maintain and manage. Therefore, pneumatic conveying has been widely used in thermal power generation, steel Smelting, cement and other industries in the handling, storage, transportation and powder engineering unit operations. In addition, with the increasingly stringent environmental protection requirements, improving industrial dust pollution will promote the sustainable development of pneumatic conveying industry.
From the appearance of pneumatic conveying system manufacturers to wide application, it has experienced the research transformation from dilute phase to dense phase, which has promoted the continuous development of pneumatic conveying. As far as the research of pneumatic conveying capacity is concerned, short-distance dense phase pneumatic conveying is still the main method, which mainly solves the problem of powder pneumatic conveying, the problem of close-distance pneumatic conveying inside or between factories, and the long-distance pneumatic conveying system, such as power plant ash removal pneumatic conveying system, due to technical limitations, it is usually realized by multi-stage relay or series system, but it is still difficult to realize long-distance pneumatic conveying in the case of limited site conditions or difficult land acquisition.
In powder production enterprises, pneumatic conveying systems are becoming more and more tense. Automation is the key to equipment, but there are still many misunderstandings about your familiarity and adaptability. The more equipment is replaced, the smaller the capacity. Why?
Imagine that the side must be more suitable for traffic than the vertical, but this is not the case. The material in the tube requires a greater air flow, because the material suspension deflection and airflow deflection in the scale tube are vertical, as long as a part of the force acts on the suspension, It will consume more energy. In a vertical pipe, the suspension deflection and airflow deflection are equal, and the pneumatic conveying equipment has a larger airflow kinetic energy. Therefore, the material is more likely to settle in the measuring tube and cause infarction, which is more conducive to the transportation of air in the vertical tube.
Increasing air volume can increase production, and to increase transport capacity, it is necessary to increase wind speed and transport volume, but the results may be bad, accordingpneumatic conveyingThe test precautions of the equipment, under the same conditions, the pipe diameter, material, conveying interval, operating conditions, wind speed, increment and conveying capacity will be greatly reduced. When the wind speed increases, the carrying capacity will increase when the air volume decreases. However, when the air volume and wind speed are close to the actual small wind speed, infarction is likely to occur. Therefore, when conveying powder particles, appropriate wind speed and air volume need to be selected, in order to obtain greater economic benefits.
