Selection steps of cyclone dust collector

Selection and calculation of cyclone dust collector mainly include the type and cylinder diameter and the number, general steps and methods are as follows. 1. The amount of gas that dust removal system needs to be processed. When the gas temperature is high, the dust content is large, the air volume and density change greatly, need to be converted. If the gas water vapor content is larger, should also consider the impact of water vapor. 2. Preliminary slect the type of cyclone dust collector according to the required treatment gas dust concentration, the nature of dust and conditions of use. 3. According the amount of gas containing dust to the need to deal with Q, to calculate dust collector diameter by the following formula; or according to the amount of gas required to calculate dust flow velocity inlet (generally between 12 ~ 25m / s), by the selected dust gas inlet speed and the amount of dusty gas to be treated to calculate the inlet cross-sectional area of the cyclone dust collector, then by the size ratio relationship of dust collector various parts to select the model. When the gas dust concentration is high, or require the capture of dust particle size is larger, should choose a larger diameter cyclone dust collector; When asked high degree of purification, or require the capture of dust particle size is fine, can choose a smaller diameter cyclone dust collector used in parallel. 4. If necessary, according to the given conditions to calculate the separation limit particle size of the dust collector and the dust removal efficiency expected, can also be directly selected by the cyclone performance table, or check the performance data against the calculation result. 5. Dust collector must use airtight good unloader to prevent air leakage in the lower part of the body, affecting the sharp decline in efficiency. The bottom of the dust collector to set up a dust box and hollow isolation cone, can reduce air leakage and vortex caused by the second dust, greatly improve the dust removal efficiency. 6. When the cyclone dust remover is used in parallel, should use the same type of cyclone dust collector, and must be properly designed to connect the duct so that each dust collector to deal with the same amount of gas, in order to avoid the flow of dust generated between the phenomenon, reduce efficiency. The way to completely eliminate the stream is set a separate dust box for each dust collector. 7. Cyclone dust collector in general should not be used in series. When must be used in series, should be used in different performance cyclone dust collector, and set the inefficient collector in the front.
