【 摘 要 】

Climate change as the global issue should be analysed from mitigating especially in the cement industrial. This industry contributes up to 6% to the global warming. Cement plants must already take over management of the cement dust arising mainly on the production. However, there are still many who are exposed to cement dust into the surrounding environment, due to the dust cement contributes to air pollutant and give impact to climate change. This research aims to study the various strategies to catch a smooth dust using fogging methods with variable water speed. In such a device, as media dust catcher is mist generated from water which is converted into mist by sprayer. The dust catcher instrument installed at the location after the end of the cement factory chimneys. Of course, in order not to complicate the technical implementation in the chimney is curved downward so it is easier to install dust extraction tool such fogging method. The tool optimal conditions occur in the water velocity 110 ml per min with an efficiency of 63.60%. In the water velocity 110 ml per min it will form a mist with the optimal amount, if the water velocity is greater than 110 ml per min will tend to form droplets, on the contrary if the water velocity is less than 110 ml per min of the amount of haze formed is not maximized.
