The important role of pneumatic conveying in waste disposal

      With the development of science and technology, solid waste treatment technology has also greatly improved. Usually, solid waste is processed through pneumatic conveying equipment. Despite the continuous development of solid waste resource utilization, it is impossible to process and utilize solid waste at 100% speed at any time due to limitations in technology, sites, economy, and other conditions. So far, the development of pneumatic conveying equipment processing technology has been very mature. It can be said that the current pneumatic conveying equipment technology represents the overall level of China's solid waste treatment industry.
Pneumatic conveying equipment should be properly handled before disposal to avoid injury. The accumulation of solid waste is also an inevitable trend, and disposal measures need to be taken. From the current actual situation, solid waste treatment accounts for a large part of solid waste treatment. The commonly used disposal methods include ground storage, incineration, chemical treatment (including neutralization, sedimentation, solidification, etc.), and landfill.
For specific solid waste, in order to choose appropriate disposal methods, in addition to considering its own physical and chemical characteristics, pneumatic conveying equipment should also consider the site, terrain, hydrogeological conditions, and economic and social environment. factor.
As a dust removal equipment, pneumatic conveying equipment has been applied in every production stage of the concrete manufacturing industry. With the continuous development of cement production technology, many production stages can only use bagged dust for production. Manufacturing should take into account emission regulations.
The more beneficial it is to increase the working capacity of the pneumatic conveying system, the more reasonable it will obviously be. However, if the dust to air ratio is too high, it will cause blockage at the same cyclone rate, and the working pressure of the pneumatic conveyor will also increase. For pneumatic and low-pressure pneumatic conveying systems, there will be more than just pneumatic cap mechanical equipment. Allowable deep suction working pressure or exhaust pipe working pressure. Therefore, the standard value of the air to air ratio depends on the physical properties of the raw materials, such as the conveyor method and its conveyor standards.
For positive pressure pneumatic conveying systems, consideration should be given to the specifications and structure of silo pumps, the nominal diameter and length of chain conveyor pipes, the number of bends, and the amount of air applied. The ash to air ratio is naturally more constrained. The traditional mechanical equipment conveyor processing technology, which consists of bucket elevators, belt conveyors, and other conveying mechanical equipment, has many disadvantages in the processing technology of grain silo inlet and outlet bin conveyors.
Pneumatic conveying equipment belongs to dense phase high-pressure pneumatic conveying. Suitable for non fragile particles A conveyor for pneumatic conveying of granular materials. The market is used in forging, chemical plants, pharmaceuticals, and grain manufacturing industries. Pneumatic conveying equipment, gas pipes, spherical tees, turbochargers, turbocharger bends, etc. form a sealed conveying system, which can be equipped with an automatic control system electronic control system, making all systems unmanned and used in conjunction with a PLC automatic control system.
