Purchase Hebei Boiler Bag Dust Collector/Yingke Environmental Protection Equipment for Customization

Product Details

The after-sales service of boiler dust collectors should pay attention to the following three points: 1. The dust concentration of boiler exhaust should first understand the allowable emission concentration of boiler smoke and dust by the local environmental protection bureau and the concentration of boiler exhaust, calculate the filtering area that the dust collector should have, and then choose the appropriate form and stage of the dust collector. The dust concentration of exhaust gas is an important indicator for selecting dust collectors. Different forms of dust collectors have different adaptability to the dust concentration of boiler exhaust gas. In general, when the inlet smoke concentration of the dust collector exceeds a critical value, the dust removal efficiency will significantly decrease. The dust concentration of boiler smoke is closely related to the type of coal used, the combustion method, and the conditions during the combustion process. To control the initial concentration of smoke and dust emissions to ensure dust removal efficiency, it is closely related to the selection of appropriate furnace type, the nature of operating load changes, and the type of fuel. 2. The flue gas volume of the boiler and various dust collectors are designed to handle the corresponding flue gas volume. When the dust collector is used under this dust removal flue gas volume, it can ensure the operating conditions of the dust collector. But when the actual load changes, the efficiency of the dust collector will also change accordingly. For example, the cyclone boiler dust collector in our boiler dust collector generally does not have a load adjustment device. When the actual load is below 70% of the design load, the dust removal efficiency will significantly decrease due to the decrease in its inlet flow rate. On the contrary, it will increase the resistance of the dust collector. In industrial boilers, the variation of flue gas volume is significant. When the boiler operates at high load, the amount of smoke and dust emitted will increase; When working at low loads, the amount of smoke and dust emitted will decrease. Therefore, when choosing a dust collector, factors such as smoke volume and changes should be considered. 3. It is the dispersion of boiler smoke and dust. Boiler fly ash is composed of dust particles of different sizes, and the particle size of smoke and dust is generally between 2-50 μ% 0m. The dispersion of smoke is usually expressed by the mass fraction of different particle sizes in the dust particles. Different forms of dust collectors have varying degrees of adaptability to the dispersion of dust particles. When the particle size of smoke and dust is above 10 μ% 0m, most stations choose centrifugal dust collectors for higher dust removal efficiency; When the particle size of smoke is below a few microns, choosing a wet dust collector has a higher dust removal efficiency. https://www.yingkehuanbao.com/
