Inert gas protection airflow explosion explosion. The whole system has explosion-proof holes in different positions in the whole line, which minimizes the loss during the bursting and explosion caused by the internal pressure and concentration of the system. The motor and other devices used in the whole system are explosion-proof motors, and the sealing performance is better, which effectively reduces the accumulation of dust.
Safety accident is always something that people don't want to touch, but in industrial processing, they will always trigger safety accidents due to different problems, causing losses of personnel and property. For users, maximum prevention and circumvention Safety hazards should be placed in the primary position of production and processing. The popularity of the airflow pulverizer allows the industry to have a leap-type development, but the airflow pulverizer is used as a mechanical equipment, and it is inexpensive to have certain hazards, especially when pulverizing and flapping and explosive materials, if ordinary air is used as a medium, dangerous coefficient The peak will be reached. In July 2015, a company in Kunshan has happened, and the safety alarm is issued to the gas flow crusher manufacturer and the user. What to do can avoid dust explosions for ultrafine processing of flammable and explosive materials? Today we will say a special airflow pulverizer for flammable and explosive materials - nitrogen protection airflow pulverizer.
The so-called dust exploding is due to the contact of the powder particles and oxygen, and the oxidation reaction completed instantaneously under certain conditions, encounters a heat source (open fire or high temperature), and the flame is instantaneously propagated over the entire mixing Dust space, chemical reaction speed is extremely fast, and release a large amount of heat, forming high temperatures and large pressure, and the energy of the system is mechanical and radiation, which has strong destructive power. It can therefore be seen that the three conditions required for dust explosion are: oxygen, ignition sources, combustible materials, as long as one of the conditions can be prevented, it can prevent the explosion. The nitrogen protection airflow pulverizer is the purpose of safe explosion-proof using control oxygen content and eliminating point fire sources.
The explosion-proof principle of nitrogen protection airflow pulverizer is by using nitrogen as a pulverized medium, the system is protected from feed, pulverization, grading, delivery, separation, and packaging. Nitrogen protection. In a fully enclosed microphone system, the oxygen content is detected and automatically oxygenated by the oxygen analyzer, and the oxygen content in the safety standard is controlled, and the oxygen content in the mixture of dust and the nitrogen mixture will be reduced to the value of the flame cannot be propagated; the oxygen content is lowered At the same time, increase the fire temperature of dust cloud, ignite energyAnd the lower limit of the explosion, so that the dust of the dust cloud is lowered, the lighting capacity is lowered. When the volume fraction of the oxygen is at a certain limit, the dust cloud cannot explode regardless of the dust cloud concentration. This value is called the ultimate oxygen content of the dust. In practical applications, a certain safety factor is often taken to the ultimate oxygen content to give the maximum allowable oxygen content. According to different materials, nitrogen can be replaced with gas such as argon, helium, carbon dioxide. Given the system in the system and the pipeline as a metal member, the dust collector is used to use a conductive filler bag, and the whole system is well grounded to try to release the static electricity of the powder. The whole system uses explosion-proof motor, electrical appliances and explosion-proof structures to ensure safe operation.
Shandong Erfa produced nitrogen protection airflow pulverizer model MQWDB-100, MQWDB-100 equipment successfully applied to many fields, so far, the pulverized and graded equipment provided by Shandong Erp I have never happened a safety accident, product quality and performance have also been well received by users. Under the strong advocacy of the country, "green sustainable development" is the main direction of major enterprises. At the same time, it has fully implemented green manufacturing, which has long been the top priority of ALPA powder technology. ALPA Powder Science and Technology Practice Green Manufacturing Concepts, and strive to create a model of traditional manufacturing transformation and upgrading.
