The coking plant is a production process that converts coal into coking coal. The coking industry is also one of the industries where air pollution is prioritized. Its unorganized dust has the double attribute of certainty and uncertainty. If improperly handled, it will cause secondary pollution. It brings certain difficulties to the control and treatment of dust. The dust generation process of the coking plant is generated from the links of material conveying, screening, crushing, loading and unloading, and transportation.

The unorganized discharge of coking enterprises has many types of pollutants, the largest smoke and dust, the most harmful, and the dust source is not fixed, contains tar, is high and has open flames, and it is difficult to treat the dust with high viscosity. Since the respirable dust with a particle size of less than 10 microns in the fine dust occupies a considerable proportion, if it is not treated and left alone, it will cause great harm to the human body and equipment. For example, when the dust containing PM2.5 is inhaled by the human body Later, deep in the human lungs, it is easy to cause various lung diseases and other diseases.
The main hazard to the equipment is that the coke dust is scattered on the rotating parts of the belt, which will accelerate the wear speed of the rotating parts, causing early damage to the machine and oil leakage. If it falls on an electrical component, it will cause component control failure, poor contact, and coverage around the motor cover and fan, which will result in poor heat dissipation of the motor, resulting in reduced motor insulation. It is important that if too much dust is used during use, it will It can cause damage to the motor and also cause explosions and other accidents.
The fugitive emission control and control independently developed by Zhengzhou Zhengfan can timely monitor fugitive emission, effectively master and scientifically analyze the data of fugitive emission distribution, concentration, change law, etc., and make governance measures tailored to local conditions based on the analysis results. Carry out intelligent and scientific governance to improve the efficiency of the management of unorganized emissions of dust.
