Analysis for you: the lowest wind speed of dust in the dust removal pipe in the dust treatment system project of the production workshop

07/09/2018 Browsing times: 1292 07/09/2018

为您分析生产车间粉尘处理系统工程中粉尘在除尘管道内的最小风速。 Noda Environment analyzes the minimum wind speed of dust in the dust removal pipe in the dust treatment system project of the production workshop.

、电除尘器、 湿式除尘器 、脉冲布袋除尘器, 旋风除尘器 ,废气净化塔等。 In the production workshop dust treatment system project, the equipment selection and design: it needs to be arranged according to the actual number and situation of dust dust spots in the workshop; it is necessary to choose different dust treatments according to the dust concentration and the dust particle size of the dust dust spots. The system and equipment for processing dust can be divided into mechanical dust collectors, bag dust collectors , electric dust collectors, wet dust collectors , pulse bag dust collectors, cyclone dust collectors , and exhaust gas purification towers.

Regardless of the type of dust collector equipment, various dust treatment systems generally use suction hoods to collect the dust-containing gas at each dust point into the dust collector body, and some of the dust settles and some of the slight dust is floated by the filter bag or swirling water. Various types of dust collector equipment have different purification effects and advantages and disadvantages. The dust generated in the production workshop is driven by the high-pressure fan to enter the upper dust processing equipment box through the dust removal pipe. After the processing equipment After treatment, the air outlet is discharged to achieve the purpose of dust purification. In the process that the suction hood collects the dust-containing gas into the dust collector equipment body, the dust removal pipeline needs to be transported.

The attached table below is the minimum wind speed required for dust treatment in the dust removal pipe of the production workshop. The following wind speed is the minimum wind speed. If it is lower than this, it will easily cause dust deposition. However, if the wind speed is too high, although the pipeline cost can be reduced, the equipment resistance and wear of the pipeline will increase a lot, so pay attention to the balance between the two when selecting.
