Dongguan dust workshop system has made significant progress
Due to the improvement of related laws and regulations, the upgrading of production technology and equipment, the aging of the original dust source control and purification equipment or backward technology, a large number of switching valve jams and other reasons, most of the dust removal systems built in the early years need to be retrofitted. The focus of the transformation lies in: ① meeting the requirements of the new regulations; ② using a closed dust extraction hood with a good effect and a small amount of air suction; ③ using (or transforming the original equipment) an efficient, low-consumption, and reliable dust removal equipment; The dust point system, based on careful calculations, uses resistance devices and air volume regulators to minimize valve usage. The “Shougang” iron smelting plant's raw material dust removal system is the latest example of this transformation. The application of air volume adjustment technology in Dongguan dustproof workshop system is becoming more and more common. In the past, only the hydraulic coupler was used to change the speed of the fan. Now there are a variety of frequency converters that are suitable for motors with different specifications, so the air volume adjustment is easier to achieve. The air volume adjustment of the dust removal system is inseparable from the flow monitoring. A continuous monitoring device for the flow of dust-containing gas has been developed. It has the characteristics of non-blocking, small resistance, and convenient application. It has played a good role in the operation of the dust removal system. Ash unloading and ash conveying technologies have also made progress. The air hammer is used to replace the vibrator, which can not only remove the dust bridge in the ash hopper, but also fluidize part of the dust, and unload the ash smoothly. In some places, the traditional ash conveying machinery is replaced by pneumatic conveying or pneumatic chute, which has the advantages of reducing the installation height of the dust collector and the investment in the project; fewer moving parts, less maintenance work and high reliability; and lower power consumption. In the case where there are several dust removal equipment, and the ash needs to be unloaded to several powder silos, a device called "medium bin distribution, gentle slope slipping" also has the same advantages.
The equipment of the Dongguan dust-proof workshop has developed rapidly, and the trend of large-scale dust collectors is obvious. The performance has reached the international level, and the filter bag and the pulse valve diaphragm have not been damaged. At present, the filter material can be used in a variety of complex environments and has better performance by processing the filter material with calendering, oil repellency, water repellency, flame retardant, anti-hydrolysis, and anti-static treatment.
The Dongguan dust-proof workshop actively promotes the improvement of production processes and equipment, and strives to achieve essential harmlessness and achieve twice the result with half the effort. Second, the industrial dust-proof technology should strive to promote the improvement of product output and quality. Furthermore, it should be more convenient to operate and maintain. .
