Fluidized bed gas flow is widely used in various industries, continuously pulverized, can keep the purity of the pulverized product, short smashing time, simple structure, the fluidized bed of the after-sales, easy to operate, small area, low area Noise!
Most of the dust particle diameter obtained by the airflow pulverizer is 5 μm or less, and the dust of 5 μm or less to the human body is the most harmful. Therefore, the use of gas flow crushing machine, the operator is suffering from dust The chance will increase significantly. Second, dust explosion may occur after large-scale disconnectation of dust in the air. Because, the dust particles of the unfairted dust particles in the gas flow crusher have a suitable particle size and distribution, generally less than 5 μm in the air, and the dispersion stability in the air is good, which is easy to reach the explosion limit. If there is sufficient combustion air around these particles, it is prone to dust explosion.
So how to solve this difficulty as a gas flow pulverizer that is often dealing with super fine powder? In fact, at the beginning of the design, the airflow pulverizer has taken into account its environmental performance, in addition to improving in the equipment process, effective measures have also been developed.
Filter dust removal equipment. Respiratory dust generated by the gas flow pulverizer: adopts foam dust removal, adding a wetting agent dust removal, ultrasonic atomization technology, composite filter bag dust removal, folding dust cloth bag, wide spacing electrostatic dust removal, dust removal effect. For dust explosion: It is appropriate to use wet dust removal, which can reduce the production of excessive dust leaks, which can reduce the oxygen concentration through the mask of water vapor, and can reduce the dust surface, thereby reducing the probability of dust explosion. From the price, wet dust removal should be used. Considering the overall performance of dust removal should be combined.
Protective measures. The prevention of respiratory dust is equally important in addition to dust removal equipment, and individual protection is equally important. Based on economics, domestic personal protective measures are mainly wearing masks. The core of the mask is filter material, and the respiratory dust is blocked and adhered by the diffusion and inertial settlement. In the mask, it is necessary to comply with the principle of human-computer engineering, except for the choice of non-toxic and tasteless and have certain tensile strength, it is also important to consider its dust-proof efficiency and respiratory resistance. The protection method of dust explosion includes isolation, disconnect and inhibition, which is mainly based on the essential conditions of dust explosion.System, for example, the source of the fire, control various static electricity, reduce dust concentration, and strengthen ventilation, etc.
Management measures. In order to reduce dust hazards as much as possible, in addition to using dust removal equipment and protective protection, the following management measures are required: (1) increase the humidity of the working area, strengthen ventilation gas, reserve fire extinguishing equipment, etc .; (2) due to most dust Composed of small particles below 10 μm, slightly drain during the manufacturing process, the dust will appear, result in contamination of the working area, so it should ensure the septality of the joint; (3) Configure protective supplies, operation according to the regulations Personnel also develop habits, properly wear protective supplies according to regulations; (4) Strengthen the safety education and training of workers 'dust knowledge, improve workers' understanding of dust hazards and prevention, and enhance the awareness of operators; (5) Dust equipment is maintained to ensure proper operation and use dustproof. At the same time, it is necessary to invest in funds, conduct technical transformation, improve the dust-proof efficiency of dustproof equipment and the level of operation.
The three dust removal methods used in production can achieve good dust removal effects, and can solve the problem of excessive dust, which is generally installed before work, and can effectively relieve the dust in the workshop. Big problem. If you want to know more about the airflow crusher, you can consult our customer service, give you a satisfactory answer.
